It - was unnecessarily large. - * Added LPC214x SPI1 driver to interface with MMC on mcu123.com board. - * Added a simple SPI-based MMC/SD block driver - * NSH: Add LPC214x-specific support to NSH; NSH now mounts any SD cards in the slot. - * FAT: Fix access to unaligned 32-bit values in partion table (start sector & size) - * Fixed a problem with a un-initialized variable in the USB serial driver. - * Added USB storage NXP LPC214x configuration - * Added a test for USB storage under examples/usbstorage - * Fixed a bug in the LPC214x USB driver: It was not properly clearing a HALTed - endpoints (other than EP) on receipt of CLEAR FEATURES request. - * Added USB storage class device side driver (BBB) - * Fixed a bug in the LPC214x USB driver: It was not properly handling request buffers - larger then the endpoint's max packet (DM320 driver also fixed, untested) - * Added logic to the USB device interface: A bit is needed to force the driver to - to terminate an IN transfer with a short packet (zero-length if necessary). - * Fix an error in the NXP LPC214x USB device driver that was causing corruption of - the request queue (M320 driver also fixed, untested) - * Correct another error in the NXP LPC214x USB device driver that caused read failures - when the request buffer size was larger than maxpacket. - * Numerous corrections/extensions to the USB tracing logic included in 0.3.16 (but - not integrated until 0.3.17) - * Fixed another bug in the NXP LPC214x USB device driver: After a stalled endpoint - is resumed (view CLEAR FEATURE), we must restart the IN (outgoing) queue. - -0.3.18 2008-11-16 Gregory Nutt - * Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711 - board (STR71x testing is stalled because I have been unable to get OpenOCD to - communicate with my JTAG wiggler on Linux). - * Fix race condition workaround delay in LPC214X SPI logic. This was also the cause of the - very bad MMC/SD performance. - * Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board - * Re-built all configurations that use SDCC and Zilog toolchains to make sure they still - build (they didn't, but they do now). - * Fixed several erroneous "list empty" checks in the CAN driver. - * Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails. - There are remaining instabilities that make the port un-usable. The nature of these is - not understood; the behavior is that certain SH-1 instructions stop working as advertised. - This could be a silicon problem, some pipeline issue that is not handled properly by the - gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the - CMON debugger. At any rate, I have exhausted all of the energy that I am willing to put - into this cool old processor for the time being. - * Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE: It now - only controls the size of the stack for the IDLE thread. Added CONFIG_USERMAIN_STACKSIZE: - This is the size of stack used with the user_start() thread is created. The two stacks - no longer have to be the same. - * Add a loop device that converts a file into a block device. - * Each NSH command can now be disabled through a configuration setting. All of these - settings make the configuration of NSH potentially complex but also allow it to squeeze - into very small memory footprints. - * Added a block to character (BCH) driver. This is kind of the reverse of the loop - device; it allows you access a block device like a character device. - * Added strcasecmp() and strncasecmp() - * NSH: Added the 'dd' command - * NSH: Added the 'losetup' command - * Fixed a FAT bug: After recent changes, it would mount a (invalid) FAT file system - even if the medium is not formatted! - * Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster - value was being reset to "1" and (2) important lseek logic was omitted when the seek - position was zero. - * Fixed a bug in getopt(). It would fail if on certain combinations of terminal argument - types. - -0.3.19 2008-11-26 Gregory Nutt - * Add poll() and select() APIs (in the initial check-in, these work only with character devices) - * Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers. - * Add examples/poll for testing poll() and select() - * Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a - full buffer of read data before return. This means that getc would stall when it needed - to refill the input buffer. The old behavior (read full blocks) might be useful in other - contexts, so it is still available within the driver as a configuration option. - * Implement poll() and select() support for TCP/IP sockets - * Fixed an important bug in the TCP/IP buffering logic. When TCP/IP read-ahead is enabled - and not recv() is in-place when a TCP/IP packet is received, the packet is placed into - a read-ahead buffer. However, the old contents of the read-ahead buffer were not being - cleared and old data would contaminate the newly received buffer. - * Implemented support for connection backlog. The size of the backlog is specified by the - second argument of the standard listen() API. Hooks are provided to support poll()/select() - waiting for connections, with a subsequent call to accept() to use the backlogged connection. - * Fixed a minor bug in accept(). It should allow the address and addresslen values to be NULL - * Added first-cut definition for a framebuffer interface (and simulated framebuffer for testing - purposes only) - * Added fixed precision math support - * Added some color converson routines into what may become a real graphics library someday. - * Added a framebuffer driver for the DM320 (untested on initial check-in) - * Network: Add support for outgoing multicast addresses - * Added some rasterizers to the graphics library - -0.4.0 2008-12-06 Gregory Nutt - * Initial release of a tiny windowing system for NuttX - * Add fixed precision sin() and cos() (not well tested at initial check-in) - * Add an X11-based simulated framebuffer driver - * The simulated target now has an option (CONFIG_SIM_WALLTIME) that will let the simulation - run in more-or-less realtime. - * Added more extensive window support: frames, toolbars, etc. - * Added support for bitmap fonts - * Integrated the new font support with a font test in examples/nx - * Add documentation for NX graphics subsystem - -0.4.1 2009-02-06 Gregory Nutt - * Added board support for the ZiLog eZ80Acclaim! ez80f910200zco Development Kit. - * Fixed several compilation errors in fixed precision math library when built - against toolchains that do not support 64-bit type 'long long'. - * Fix errors in some function prototypes in dirent.h - * Add eZ80F91 EMAC driver - * Fix recvfrom() compilation error: only noted under ZDS - * Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are - still some build issues associated with that toolchain in use of arm-elf-objcopy - -- see the TODO.txt list for details) - * Fix problems with Z16F and eZ80 compilation introduced with recent changes. - -0.4.2 2009-02-28 Gregory Nutt - - * M16C: Add support for the Renesas M16C MCU and the SKP16C26 StarterKit. However, - the target cannot be built because the GNU m16c-elf-ld link fails with - the following message: - - m32c-elf-ld: BFD (GNU Binutils) 2.19 assertion fail /home/Owner/projects/nuttx/buildroot/toolchain_build_m32c/binutils-2.19/bfd/elf32-m32c.c:482 - - Where the reference line is: - - /* If the symbol is out of range for a 16-bit address, - we must have allocated a plt entry. */ - BFD_ASSERT (*plt_offset != (bfd_vma) -1); - - No workaround is known at this time. This is a show stopper for M16C. - - * eZ80Acclaim!: Fix interrupt vectors positioning; they were being positioned - wrong by 64 bytes (Kevin Franzen). - * eZ80Acclaim!: Corrected some stack handling errors during interrupt handling - context save and restore (Kevin Franzen). - * eZ80Acclaim!: Corrected vector initialization logic (Kevin Franzen). - * eZ80Acclaim!: Corrected overflow problem in the calculation of UART baud rate - divisor, the system timer divisor, and the EMAC poll timer. - * eZ80Acclaim!: Fixed GPIO pin configuration get serial output - * eZ80Acclaim!: Correct stack overflow in ostest example configuration - * eZ80Acclaim!: Fixed restoration of interrupts state on interrupt level context swith. - -0.4.3 2009-03-04 Gregory Nutt - - * z8Encore! and eZ80Acclaim!: Fixed the serial driver initialization sequence - * eZ80Acclaim!: Fixed error in vector table: Missing space set aside for the - "unused" vectors.

The - driver is basically functional and should mature prior to the 0.4.3 release. - * Implemented priority inheritance logic for POSIX semaphores. Because the pthread - mutexes are built on semaphores, they will have this property as well. - -0.4.4 2009-03-29 Gregory Nutt - - * examples/nsh: A debug option was left on that can (and does) cause - infinite loops and stack overflows. - * net/uip: Correct calculation of checksum on ICMP ping response. - * examples/dchpd: Added a tiny DHCP server example - * net/uip: Correct UDP bind behavior. It should select a valid port number - if it receives a port number of zero. - * netutils/dhcpd: correct for ZDS compiler. Fix issue with re-use of a - port number. Fixed a number of broadcast-related problems. - * eZ80Acclaim!: Add a tiny webserver configuration - * eZ80Acclaim!: Fixed an important bug in the EMAC Tx timeout logic. It was - always timing out when the load was heavy and worse, for some reason, - resetting the Tx function caused unexpected registers to be reset in - the Rcv function was well. - * Z80: Patch incorported: "[2696648] Z80: interrupt flag stored in parity bit" - (submitted by JPelletier). The is the same fix that was needed for the - eZ80 and fixed in 0.4.2. - * netutils: Added logic to support a simple wget() function - * examples/wget: Added a test for wget() (untested -- see NOTE) - * lib/strncasecmp: Fix cut'n'paste error in function name. - * NSH: Added wget command (untested -- see NOTE). - * examples/sendmail: A simple sendmail example (untested -- see NOTE) - - NOTE: Features related to wget and sendmail are not tested on the target platform - in this release and, hence, most likely have problems. I don't have the correct network - setup to perform that testing now (I'm in a hotel). - -0.4.5 2009-04-19 Gregory Nutt - - * Add an enumeration argument to the SPI chip select and status methods so - that the interface can handle more than one device. - * eZ80Acclaim!: Add a generic SPI driver for all eZ80 boards. - * Add a setmode() method to the SPI interface to handle parts with differing - mode requirements. - * include/nuttx/i2c.h: Defined a standard I2C interface - * eZ80Acclaim!: Add an I2C driver. - * eZ8Encore!: Add an I2C driver. - * Add support for the Freescale i.MX1/L architecture and a configuration for - the Freescale MX1ADS development board. - * examples/helloxx: Added a simple C++ hello world example - * include/css: Added std header files - * libxx: New C++-only directory provides support for minimal C++ applications - -0.4.6 2009-05-19 Gregory Nutt - - * Change SPI interface so that is can accommodate interfaces where the - number of bits per word is greater an 8 (such as with many 9-bit display - interfaces). -- this might have broken a few things which will need to - be retested! - * arch/arm/src/imx: Added i.MX SPI driver - * SPI: Add a method to set the number of bits per word. Also add an - alternative interface for so that (eventually) I can phase the sndblock - and recvblock methods and replace them with a single exchange method - * Build: objcopy fails with toolchains that use newer GCC and binutils. The - following arguments need to be included in the objcopy command line "-R .note - -R .note.gnu.build-id -R .comment" This has been fixed in arch/arm/src/Makefile, - but other architectures may have the same problem. Thanks to Dave Marples - for verifying this. - * configs/eagle100/ostest: Added support for the MicroMint Eagle100 board. - This board has a Luminary LM3S6918 Cortex-M3.

Bad frequency - calculation based on CSD settings, inappropriate timeouts, odd code that looks like - a bad search and replace. Also needs support for SDHC ver 2.x. New MMC/SD is - largely redesigned and probably non-functional in the first check-in. - * drivers/mmcsd: Changes verified on 4Gb Kingston microSHDC card and on a 2Gb - SanDisk microSDC card on the Eagle100 platform. - * fs/fat: With the 4Gb card, the first tests of FAT32 were (finally) performed. - Found and corrected a problem that prevented use of FAT32: It was not updating - the sector cache before checking the FAT32 FSINFO sector. - * configs/eagle100/*/Make.defs: Added configuration options that should make - it possible to build NuttX for the Eagle100 using CodeSourcery 2009q1 toolchain - and the devkitARM GNU toolchain. - * configs/mcu123-lpc214x/src: Corrected some logic in the LPC2148 SPI receive block - logic.

There are CMD0 issues with the 2Gb SanDisk SDC on this board. - * fs/fs_mount.c: Corrected error handling that could cause a deadlock on certain - mount() failures. - -0.4.8 2009-06-13 Gregory Nutt - - * lib/lib_*stream.c: Extend internal stream logic to support incoming streams. - * arch/arm/src/str71x: Serial output is now correct and timer interrupts are - working. The test at configs/olimex-strp711/ostest passes. This means that - the basic STR-P711 port is complete. - * configs/olimex-strp711/nsh: Add and verified a NuttShell (NSH) configuration - for the STR-P711. - * arch/arm/str71x/str71x_serial.c: The STR711 interrupt driven serial driver - finally works after some extradinary measures to handle missed interrupts. - NSH is fully functional on the Olimex STR-P711 board. - * example/nsh: Moved architecture specific files from NSH directory to board- - specific directories. - * config/olimex-strp711/src/up_nsh.c: Add an NSH board specific directory for - for the Olimex STR7P11 board. - * Fixed build of LM3X6918 using the CodeSourcery Windows native toolchain. There - were lots of issues with Cygwin paths and Cygwin symbolic links. These changes - may work with the devarmKIT as well, but that remains untested. - * The NXP LPC2148 and STR711 targets can now also be built using the CodeSourcery - or devkitARM Windows native toolchains. - -0.4.9 2009-06-26 Gregory Nutt - - * Add strtoll() and strtoull(); Add macros for atol() and atoll(). - * dup() and dup2() will now clone socket descriptors - * All socket descriptors are now cloned when a new task is started via - task_create(). - * Add configuration options to suppress or eliminate cloning of file - and/or socket descriptors when a new task is started by task_create(): - CONFIG_FDCLONE_DISABLE, CONFIG_FDCLONE_STDIO, CONFIG_SDCLONE_DISABLE. - * Use of C++ reserved word 'private' in C header files causes problems - for C++ that include them. - * Added 'binfmt' support to allow execution of programs in a file system, - binding to NuttX symbols. A custom format call NXFLAT is used; this - derives from http://xflat.sourceforge.net. At present is supports on - XIP execution from ROMFS file systems. Initial check-in is untested - and probably breaks many builds. - * examples/lib: Added qsort() - * examples/nxflat: Added support for symbol tables - * Correct logic that creates compiler include paths. On Cygwin, the - include paths for Cygwin-based GCC were being converted to windows - native paths. That causes many problems -- breaking dependencies - for one. - * Fixed an important bug in ROMFS. The initial XIP offset was set - incorrectly so if sector zero was read first, there was a bad read. - I don't know how it worked before. - * arch/arm/src/common/up_use_stack.c. Fixed a fatal stack setup error. - This file has been around for a long time, but I don't think it has - every been used before (i.e., prior to the NXFLAT logic) - -0.4.10 2009-08-08 Gregory Nutt - - * lib/: Added some basic regex-subset, pattern matching functions - * lib/: Greatly simplified mktime() and gmtime_r(). The Gregorian and - Julian time calculations were interesting, but not necessary in the - typical embeddd system. - * sched/: Added gettimeofday(). This implementation is simply a thin - wrapper around clock_gettimer(). - * lib/: Add gmtime(), localtime(), and strftime() - * binfmt/: Add exec(). This is just a wrapper that executes both - load_ and exec_module() in a more familiar manner. It is not consistent - with more standard exec() functions, however, because (1) it returns - and (2) it requires symbol table arguments. - * lib/: Add fileno() - * examples/ostest: Several of the tests used a big, hard-coded stack size - when creating test threads (16K stacksize). The stack size should - be controlled by the .config file or the OSTest won't work on platforms - with memory constraints. - * netutils/thttpd: An initial port of Jeff Poskanzer's THTTPD HTTP server. - See http://acme.com/software/thttpd/. - * examples/thttpd: A basic test program for THTTPD - * configs/eagle100/thttpd: A build configuration for THTTPD on the Micromint - Eagle-100 LMS6918 (Cortex-M3) board. - * configs/ntosd-dm320/thttpd: A build configuration for THTTPD on the Neuros - DM320 platform. - * lib/: Added strstr() and strpbrk(). - * net/recvfrom.c and net/accept(): Sockets now support some non-blocking - operations, specifically for (1) TCP/IP read operations when read-ahead - buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP - connection backlog is enabled. - * fs/fs_fcntl.c and net/net_vfcntl.c: Minimal support provided for fcntl(). - It can, at least, be used to mark sockets as blocking or non-blocking. - * net/net_close.c: Fix bug in close(). If reference count not set to zero - then uip_tcpfree() will assert when DEBUG is enabled. - * net/accept.c: Fix bug in accept(). The logic expected parts of the - return address structure to be initialized or it would return an error. - -0.4.11 2009-09-16 Gregory Nutt - - * fs/fs_read.c and fs/fs_write.c. read() and write() to socket is the - same as recv() and send() with flags = 0. Fixed! - * net/recvfrom.c: Fix errors in return value from non-blocking socket read. - * lib/lib_strcasecmp.c and lib/lib_strncasecmp.c. Use of post-incremented - argument to macro caused strcasecmp() and strncasecmp() to fail. - * lib/lib_strstr.c: Length of substring off by one causes false alarm - sub-string matches. - * arch/arm/src/lm3s/lm3s_ethernet.c: Fix errors in LMS6918 FIFO length - handling. (1) The incorrect size of the Ethernet header was being - subtracted on outgoing messages (4 vs 14), which caused outgoing messages to - be a little too long. (2) The size of incoming FIFO messages is 6 bytes - larger than it expected (2 for the length and 4 for the FCS). The unhandled - extra two bytes of length cause the driver to sometimes read one too many - words from the received FIFO (corrupting the next queued receive packet, - if any). - * net/net_poll.c and net/uip/uip_tcpbacklog.c. Fixed an important race condition - bug in polling for connections. The logic worked if the poll was inplace - before the connection was received; but the poll failed to awaken if the - connection was already pending in the backlog when poll() was called. - * net/net_close.c. Fixed another important TCP/IP race condition bug: If - the host closes the TCP connection just before the target calls close(), then - the close operation may hang indefinitely! - * net/net_tcppoll.c. Removed an unnecessary check for outstanding, un-ACKed - data. The NuttX socket layer keeps track of ACKs and doesn't need this check; - removing the check should improve write throughput - * Add DEBUG configuration option to enable debug console output without disabling - optimization (and vice versa) - * Changed lots of occurrences of debug macro dbg() to lldbg(). dbg() uses - stdout to output debug data. That works fine unless (1) the dbg() macro - is interrupt logic and the interrupted task has redirected stdout! Most - changes were in uIP. - * net/uip/uip_tcpinput.c. Connection reference count was not being set correctly - when a socket is created by accepting a new connection. Since the reference - count is bad, such sockets are not successfully duplicated when being passed - to new tasks. - * net/net_clone.c. Similarly, after a socket is cloned, its reference count - was not being initialized. - * lib/lib_strstr.c. Improperly incremented pointer could cause comparison - failures. - * net/. Connection reference count must always be set to zero before calling - uip_tcpfree() or it could trigger a DEBUGASSERT that verifies that the - reference count is zero before freeing a connection structure. - * net/uip/uip_listen.c. uip_accept() consulted the wrong list to find the - listener on a socket. The previous logic worked most of the time, but - occasionally picked the wrong listener. - * net/net_close.c and net/net_sockets.c. Sockets were not being closed - when a task exits. If many server tasks are created and exit without closing - sockets (such as with CGI tasks), then eventually, you will run out of sockets. - * netutils/thttpd. Basic functionality of THTTPD is complete. This includes - serving up files from a file system and executing NXFLAT-based CGI programs - and pipe the stdout back to the HTTP client. - -0.4.12 2009-10-17 Gregory Nutt - - * arch/arm/src/stm32 and configs/stm3210e-eval. Added basic support for the - STMicro STM32, Cortex-M3 MCU. The specific port is to the STMicro STM3210E-EVAL - development board based around the STM32F103ZET6 MCU. - * configs/stm3210e-eval/RIDE. Added a basic STMicro RIDE7 project that can be - used to perform basic STM32 board bring-up (due to RIDE7 size limitations, it - cannot be used for the full NuttX bring-up). - * configs/stm3210e-eval/ostest. The STM32 now passes the basic NuttX OS test - at examples/ostest. The rest should be a piece of cake. - * configs/stm3210e-eval/nsh. Added NuttShell (NSH) example. - * configs/stm3210e-eval/src/stm32102e-internal.h. Fix on-board LED GPIO definitions. - * arch/arm/src/stm32/src/stm32/stm32_dma.c. Added DMA channel support for the STM32 - * arch/arm/src/stm32/src/stm32/stm32_spi.c. Added a DMA-based SPI driver for the STM32. - * arch/arm/src/stm32/src/stm32/stm32_serial.c. Finished interrupt-driven, - USART console driver. This makes NSH work perfectly. - * Things left to do for the STM32 deferred to the 0.4.13 release: USB device driver, - LCD driver and NX bringup on the eval board's display and MicroSD support. An SPI - driver was included in the 0.4.12 release, but is not yet tested. - -0.4.13 2009-11-04 Gregory Nutt - - * include/nuttx/mtd.h. Added a simple interface definition to support some - FLASH, EEPROM, NVRAM, etc. devices. - * driver/mtd/m25px.c. Added a driver for SPI based FLASH parts M25P64 and M25P128. - * configs/stm3210e-eval/usbserial. Add a USB serial configuration for the STM32. - Depends on the STM32 USB driver. - * arch/arm/src/cortexm3/up_switchcontext.S & up_svccall.c. Made an improvement - to context switching. There are two types of context switches: interrupt - context switches and background/user context switches. This change should - improve the performance of those background/user context switches by a factor - of about two. - * arch/arm/src/stm32/: Fix several typos in the serial logic. It turns out - that these typose don't make any difference as long as you use only one - serial port and all uarts are configured the same. But the typos are bugs - waiting to happen in any other configuration. - * arch/arm/src/stm32/: You have to configure CTS/RTS function pins for USART - 2 and USART 3 even if you are not using flow control. - * arch/arm/src/stm32/stm32_usbdev.c: Added a USB device-side driver for the - STM32. NOTE: This is an early release of the USB driver. There is at least - one known issue. The examples/usbserial test only executes correctly under - certain conditions (see the full bug description in the TODO list). - * arch/arm/src/stm32/stm32_rcc.c: Fixed an error in clock initialization. - On some boards (none of mine), the HSE (high speed external clock) delay - loop times out if the optimization level is high. The STM32 then falls - back to the HSI (internal clock), and the system clock is too slow by a - factor of 11.1%. This was fixed by simply add the volatile storage class - to the timeout loop counter - * arch/arm/src/stm32/stm32_irq.c: Fixed a critical bug in the interrupt - control logic. The wrong register was being used for interrupts in a - certain range. Worked fine until you try to use an interrupt in that - range! - -4.14 2009-12-02 Gregory Nutt - - * arch/arm/src/stm32/stm32_gpio.c: Add support for configure an input GPIO - to generate an EXTI interrupt. - * config/stm3210e-eval/src/up_buttons.c: Add support for on-board buttons. - * include/nuttx/rwbuffer.h: Add generic support for read-ahead buffering - and write buffering that can be used in any block driver. - * include/nuttx/wqueue.h: Added a generic worker thread that can used to - defer processing from an interrupt to a task. - * include/nuttx/sdio.h: Defines a generic SD/SDIO interface can can be - bound to a MMC/SD driver to provide SDIO-based MMC/SD support. - * drivers/mmcsd/mmcsd_sdio.c: Provides an SDIO-based MMC/SD driver. - * arch/arm/src/stm32/stm32_sdio.c: Provides an STM32 implementation of - the SDIO interface defined in include/nuttx/sdio.h. - * fs/fs_mount.c: Correct error handling logic. If the bind() method - fails, then a reserved node is left in the tree. This causes subsequent - attempts to mount at the location to fail (reporting that the node - already exists). This is a problem for block drivers for removable - media: The bind method could fail repeatedly until media is inserted. - * arch/arm/src/stm32/chip.h & stm32_dma.c: Fixed several definitions - that can cause compilation errors when DMA2 is enabled. - * arch/arm/src/stm32/stm32_dma.c: Integrated and debugged STM32 DMA - functionality that was added in 0.4.12. - * configs/stm3210e-eval/usbstorage: Add a configuration to exercise - the STM32 with the USB mass storage device class example - (examples/usbstorage). - * configs/mcu123-lpc214x/up_usbstrg: Move LPC-specific code from - examples/usbstorage to configs/mcu123-lpc214x. - * configs/stm321e-eval/up_usbstrg: Add STM32-specific logic for the - examples/usbstorage test. - * arch/arm/src/stm32/stm32_usbdev.c: Fix bugs in STM32 USB device-side - driver: (1) Need to disconnect after reset received, (2) Status setup - to recover from stall on TX endpoint. - -5.0 2009-12-21 Gregory Nutt - - * arch/hc: Adding framework to support m68hc11/12 - * configs/demo9s12ne64: Configuration to support Freescale DEMO9S12NE64 - development board (MC9S12NE64 m68hcs12 processor). - * drivers/mtd/ftl.c: A FLASH translation layer (FTL) has been implemented. - This layer will convert a FLASH MTD interface into a block driver that - can be used with any file system. Good performance of this layer will - depend upon functioning write buffer support! - NOTE: FTL support is untested as of the initial check-in. - * Numerous minor changes for m68hc12 to eliminate compilation errors and - warnings due to the fact that it uses 16-bit integer types and for casts - between uint32 (32-bits) and an mc68hc12 pointer (16-bits). - * sys/types: Size of off_t and blkcnt_t should not depend on size of - int in the architecture; Removed non-standard type STATUS - * include/: Added header files stdint.h, stdbool.h, cxx/cstdint, and - cxx/cstdbool - * Changed ALL references to non-standard fixed-size types (like uint32, - ubyte, etc.) to standard types (like uint32_t, uint8_t, etc.) from - stdint.h. Use type bool and {true, false} from stdbool. This effected - most of the files in the system! Almost all configurations have been - re-built and many have been re-verified in order to get confidence in - these changes. - * graphics/ and examples/nx: Fix numerous build errors that have been - introduced lately. NXGL has suffered some bit-rot from not being used - in some of the most recent ports. - * The misc/pascal NuttX add-on package has been updated to use the new - standard types from stdint.h and stdbool.h and re-integrated with NuttX. - The released pascal-2.0 will be the first version that contains the - compatible changes. - * arch/arm/src/lm3s/lm3s_ethernet.c: Fixed an important bug in the LM3S - Ethernet driver: If full packet is received, the packet-too-big check - will fail because it needs to subtract 6 from the packet size (to - account for the 2-byte packet length and the 4-byte packet FCS in the - FIFO). - * net/accept.c: Fixed a bad assertion (only happens when debug is enabled). - * net/send.c net/uip/uip_tcpseqno.c: Fixed a critical error in the TCP/IP - logic. The NuttX port of uIP imcludes logic to send data ahead without - waiting for ACKs from the recipient; this greatly improves throughput. - However, the packet sequence number was not being updated correctly and, - as a result, packets were not be ACKed by the recipient and transfers - would sometimes stall. This is a very important bug fix (in fact, I - don't understand how TCP/IP worked at all without this fix???) - * include/nuttx/arch.h and arch/*/common/up_udelay.c: Change argument - of up_udelay() to type useconds_t to avoid warnings when sizeof(int) - is 16-bits. - * drivers/mmcsd/*: Add casts in constant expressions to avoid warnings - when sizeof(int) is 16-bits. - -5.1 2010-01-30 Gregory Nutt - - * arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework - to support the NXP LPC3131. - * Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131 - (LPC3131) is code complete and waiting for me to get hardware in - hand. - * arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek - - Added the basic framework needed to begin a port for the SAM3U-EK - development board. - * lib/lib_crc32.c: Add CRC32 logic by Gary S. Brown to lib/. This is - the larger (but faster) table look-up version of the CRC32 algorithm. - * configs/ea3131/tools: Added a tool to create a image suitable for - use with the LPC313x bootloader. - * configs/sam3u-3k/ostest: Completed verification of the basic NuttX - OS test for the SAM3U. - * arch/arm/src/common/up_createstack: stack was always been cleared - when it was allocated. This is a good feature for monitoring the - stack during debug, but really hurts thread start-up performance. - Clearing is now done if CONFIG_DEBUG=y only. Changes was only made - for arm, but really should be made for all architectures. - * configs/sam3u/nsh: Added NSH configuration for SAM3U - -5.2 2010-03-18 Gregory Nutt - - * arch/arm/src/sam3u/sam3u_pio.c: Fix an address calculation error - that caused ports B & C to get mapped to the PIOA base address. - This is an important bugfix! (a patch is available) - * arch/arm/src/lpc313x/lpc313x_boot.c: Fix an error in the vector - initialization was causing a memory fault. - * lib/lib_strtod.c: Add strtod() - * lpc3131/ea3131: Several bring fixes submitted by David Hewson. The - lpc3131 is almost there! Thanks David! - * arch/arm/src/arm/up_head.S: Corrected backward conditional compilation - that selects if vectors are located at 0x0000:0000 or 0xffff:f000. - This fixes the last show stopper bug in the lpc313x bring-up. - * configs/ea3131/nsh: Added a NuttShell (NSH) configuration for the - EA3131. - -5.3 2010-04-11 Gregory Nutt - - * arch/arm/src/lpc313x/lpc313x_usbdev.c: USB driver for the LPC313x - contributed by David Hewson. - * configs/ea3131/src/up_ubstrgc.c, configs/ea3131/usbserial, - configs/ea3131/usbstorage: USB storage and USB serial example support - contributed by David Hewson. - * Several important compilation error fixes in lpc313x and (dualspeed) USB - code also contributed by David Hewson. - * arch/arm/src/sam3u/sam3u_dmac.c: DMA support for the AT90SAM3U. - * arch/arm/src/sam3u/sam3u_hsmci.c: SD memory card support for AT90SAM3U - (Neither the DMA nor the HSMCI driver are functional on the initial checkin). - * drivers/usbdev: Several important fixes to the USB mass storage driver - submitted by David Hewson. - * configs/olimex-lpc2378, arch/arm/include/lpc2378, and arch/arm/src/lpc2378 - - Basic port of the NXP 2378 on the Olimex board contributed by - Rommel Marcelo. - * arch/arm/src/sam3u/sam3u_internal.h: Fixed a critical bug in the AT91SAM3U - PIO decoding. No PIOs greater than 15 could be used on any port! Obviously, - no one has been using this port. - -5.4 2010-04-23 Gregory Nutt - - * include/nuttx/lcd.h: Defines an LCD interface. - * graphics/nxglib/fb and lcd: Support LCD and framebuffer rasterizers for NX. - * configs/sam3u-ek/src/up_lcd.c: LCD driver for LCD on SAM3U-EK development - board. - * configs/sam3u-ek/nx: NX graphics configuration for the SAM3U-EK - -5.5 2010-05-09 Gregory Nutt - - * drivers/net/enc28j60.c: Microchip ENC28J60 SPI Ethernet chip driver. - (untested on original check-in). - * configs/olimex-str7p11/nettest: examples/nettest configuration using - the ENC28J60 driver on the Olimex STMicro STR-P711. - (unverified on original check-in) - * configs/olimex-str7p11/src/up_enc28j60.c: Add ENC28J60 initialization - logic. - * configs/olimex-str7p11/src/up_spi.c: Fixed some bugs; added support - for ENC28J60. - * arch/arm/src/str7x/str7x_xti.c: Add basic XTI support (external - interrupts). - * arch/arm/src/lm3s and arch/arm/include/lm3s: Add definitions for - LM3S6965 - * configs/lm3s6965-ek: Add configuration for Stellaris LM3S6965 - Evaluation Kit (including basic examples/ostest configuration) - * lib/lib_dtoa.c and lib/lib_dtoa.c: printf will not print floating - point values if you select CONFIG_LIBC_FLOATINGPOINT in your - configuration file. Contributed by Yolande Cates. NOTE: these - floating point operations have not been well tested and may not - be portable to all floating point implementations. - * configs/lm3s6965-ek/nsh: Added NuttShell (NSH) configuration for - the LM3S6965 Evaluation Kit. Includes both serial and telnet - interfaces. - * net/net_close.c: Correct a UDP reference counting error - -5.6 2010-06-05 Gregory Nutt - - * drivers/lcd/p14201.c: Driver for RiT P14201 series 128x96 4-bit OLED. - * configs/lm3s6965-ek/nx: NX graphics configuration for the LM3S6965 - Ethernet Evaluation Kit. - * graphics/: Numerous fixes to get the P14201 4-bpp grayscale display - working (there may still be some minor issues .. see the TODO list). - * arch/arm/include/lpc17xx and arch/arm/src/lpc17xxx: Began port for - NXP LPC1768. As of the 5.6 release, there is a complete set of - LPC17xx header files defining all bits in all LPC17xx registers, - but little else (I still do not have hardware in hand). - * drivers/mtd/m25px.c: Add support for M25P1 flash part (See NOTE) - * include/nuttx/i2c.h: Extended I2C interface definition to handle - multiple transfers (See NOTE). - * include/nuttx/usbdev.h: Corrected an important macro definition - needed to correctly handle USB null packet transfers (See NOTE). - * arch/arm/src/lpc313x: New drivers: I2C and SPI. Plus several - important LPC313x USB bug fixes (See NOTE). - - NOTE: Contributed by David Hewson. - -5.7 2010-06-22 Gregory Nutt - - * configs/nucleus2g: Add ostest configuration for the Nucleus 2G - LPC1768 board from 2G Engineering (http://www.2g-eng.com/) - * arch/arm/src/lpc17xx: Added basic LPC17xx boot-up logic, - interrupt handling, and GPIO configuration. - * configs/nucleus2g/ostest: Completed bring-up of LPC1768 on - the Nucleus2G board using the examples/ostest - * configs/nucleus2g/nsh: Added and verified a NuttShell (NSH) - configuration for the LPC1768 on the Nucleus2G board. - -5.8 2010-07-18 Gregory Nutt - - * configs/nucleus2g/src/up_nsh.c and up_ssp.c: Add support - for SPI-based MMC/SD cards and integrate into the NSH example. - * arch/arm/src/lm3s/lm3s_vectors.S: Correct vectors for GPIOC & D - interrupts. - * arch/arm/src/lpc17xx/lpc17_clockconfig.c: Power was not being - provided to GPIO module.

This is not expected to be a functionality configuration (at - least not yet); it was created in order to debug the on-demand paging - feature. - * configs/ntosd-dm320/*/Make.defs: Codesourcery and devkitARM toolchains - now supported for the Neuros OSD. - * configs/ntosd-dm320 and arch/arm/src/dm320: Add support for the - Neuros production OSD (changes contributed by bf.nuttx). - -5.10 2010-09-07 Gregory Nutt - - * configs/ea3131/locked: Create logic to support a two pass build - process: The first pass forces critical logic into the locked text - region, the second pass builds the NuttX executable more-or-less as - normal. - * Makefile, arch/arm/src/Makefile, configs/ea3131: Add logic to - support a two-pass final link. This logic is only in place in - the arch/arm/src/Makefile for now. - * arch/arm/src/lpc17xx/lpc17_internal.h: Add missing parentheses in - macros definitions (patch submitted by Tiago Maluta). - * Documents/NuttxPortingGuide.html, configs/README.txt, etc. - - Replaced CONFIG_EXAMPLE with CONFIG_APP_DIR (see documents for - description). This allows NuttX application code to be built - outside of the examples/ directory. - - For people who have their own configurations and/or Makefiles, - you will need to make a couple of changes: - - - Replace all occurrences of CONFIG_EXAMPLE=foobar with - CONFIG_APP_DIR=examples/foobar in all of the configuration - files. - - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with - $(CONFIG_APP_DIR) - - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) - with libapp$(LIBEXT) in your Makefiles. - - Check any other occurrences of CONFIG_EXAMPLE. - - * arch/arm/src/lpc313x/lpc313x_spi.c: Fix compilation error when - when CONFIG_DEBUG is enabled. - * arch/arm/src/lm3s and arch/arm/include/lm3s: Support for the - lm3s8962 contributed by Larry Arnold. - * configs/lm328962-ek: Support for the TI/Stellaris EKC-LM3S8962 - board (also contributed by Larry Arnold). - * arch/arm/src/lpc313x/lpc313x_boot.c: The call to lpc313x_boardinitialized() - should not be conditioned on CONFIG_ARCH_LEDs being defined! - * arch/arm/src/lpc313x/: APB0 and APB1 cannot lie in different - sections; they are too close together. - * arch/arm/src/lpc313x/lpc13x_boot.c: Resetting all of the clocking - had a side effect of wiping out the first 6 words of memory where the - interrupt vectors are located (and also not resetting the fractional - dividers). This is not usually noticeable because the IRQ vectors - are after this point, but really causes problems if you want to handle - data and prefectch aborts which are within this zeroed region. - -5.11 2010-10-01 Gregory Nutt - - * configs/ea3131/src/up_fillpage.c: Added new configuration item - CONFIG_PAGING_BINPATH. If CONFIG_PAGING_BINPATH is defined, then it - is the full path to a file on a mounted file system that contains - a binary image of the NuttX executable. Pages will be filled by - reading from offsets into this file that correspond to virtual - fault addresses. up_fillpage.c implements logic to perform page - files using the CONFIG_PAGING_BINPATH file. - * configs/mbed: Add configuration to support the mbed.org LPC1768 - board (Contributed by Dave Marples). - * sched/sem_wait.c and sem_waitirq.c: Eliminate a race condition - that can occur when a semaphore wait is interrupt by a signal. - (see email thread: https://groups.yahoo.com/neo/groups/nuttx/conversations/messages/530) - * drivers/mtd/at45db.c: Add a driver for the Atmel AT45DB161D 4Mbit - SPI FLASH part (untested on initial check-in). - * arch/arm/src/lm3s and arch/arm/include/lm3s: Corrections for the - lm3s8962 port contributed by Larry Arnold. That port is purported - to work correctly with these changes in place. - * examples/ostest/prioinherit.c: Need to reinitialize globals if - test is ran repeatedly in a loop. - * configs/ez80f910200zco: Updated to used ZDS-II 4.11.1 - -5.12 2010-10-26 Gregory Nutt - - * arch/avr: Add a place to support AVR family processors. - * arch/avr/include/avr32 and arch/avr/src/avr32: Add support for AVR32 - (all of the AVR32 is a work in progress). - * arch/avr/include/at32uc3 and arch/avr/src/at32uc3: Add support - for the AVR32 UC3A/B family of AVR32 MCUs. - * configs/avr32dev1: Add support for the Atmel AVR32DEV1 board featuring - the AT32UC3B0256 MCU. This board is produced by www.mcuzone.com. - * include/stdlib.h, lib/Makefile, lib/lib_abs.c, lib/lib_labs.c, - lib_labs.c, lib_llabs.c, lib_imaxabs.c: Add abs(), labs(), llabs(), and - imaxabs(). - * Add include/inttypes.h - * arch/hc/src/mc9s12ne64: This hcs12 port grew a few more files. But it - is still a long way from complete. - * arch/*/src/*/*_sigdeliver.c: Fixed a serious error in the signal - trampoline logic. Essentially, interrupts are re-enabled while the - signal handler executes, but the logic to re-disable the interrupts - before returning from the signal handler trampoline was missing. Under - certain circumstances, this can cause stack corruption. This was - discovered by David Hewson on an ARM9 platform, but since the code - has been leveraged, the bug has been propogated from ARM to Cortex-M3, - AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 -- almost every architecture. - The correction has been incorporated for all architectures but only - verified on a few. - -5.13 2010-11-09 Gregory Nutt - - * lib/lib_strnlen.c: Added POSIX 2008 strnlen() function. Contributed - by Michael Hrabanek. - * Fix wild, consistent naming error. For some reason, I called the at32uc3* - parts at91uc* everywhere. Fixed by changing lots of files and directories. - * configs/avr32dev1/ostest: The AVR32 port now successfully passes the - examples/ostest. We have a good AVR32 port! - * configs/avr32dev1/nsh: Added a configuration to support the NuttShell - (NSH). As of this writing, here is a problem receiving serial data (this - is, very likely, my hardware setup). - * lib/lib_open.c: Fix an error in fdopen when a valid file descriptor does - not refer to an open file. - * configs/olimex-lpc1766stk: Add support for the Olimex LPC1766-STK - development board. The OS test and NSH configurations (only) have been - verified. - -5.14 2010-11-27 Gregory Nutt - - * configs/olimex-lpc1766stk/nettest: Add examples/nettest configuration to - verify the LPC17xx Ethernet driver currently under development. - * arch/arm/src/lpc17xx/lpc17xx_ethernet.c/.h: Began development of - the LPC17xx Ethernet driver. Driver in CVS functional after 2010-11-23. - * sched/timer_settime.c: Fix an error in set-up of a one-shot POSIX timer. It - was using the repititive timer value (which is zero in the one-shot case), - always resulting in a 10Ms timer! Found and fixed by Wilton Tong. - * arch/arm/src/lpc17xx/lpc17_vector.S, stm32/stm32_vector.S, lm3s/lm3s_vector.S, - sam3u/sam3u_vector.S: Fixed a hard fault problem that can occur if certain - types of interrupts are pending at the time another interrupt returns - (SYSTICK). This has not been verified on all plaforms, but is a critical - fixed that is needed by all Cortex-M3 NuttX users. - * configs/olimex-lpc1766stk/thttpd: Add a THTTPD configuration for the - Olimex LPC2766-STK board. Verified successfully. - * net/uip/uip_tcpappsend.c: Correct an important logic bug in some uIP state - data the is used to manage retransmissions. The uIP logic was incompatible - with the retransmission logic of net/send.c in one place. The final error - was that the final packet in a sequence of packets was too large! In the - THTTPD example, this would leave some garbage at the bottom of the display - (or worse). I don't know why I haven't see this bug before??? - * net/uip/uip_tcpinput.c: The change to uip_tcpappsend.c unmasked an - additional error in the TCP sequence number handling. This sympom was that - the send() function would hang with outstanding, unacknowledged data (with - no re-transmit requests). The was due to differences in sequence number - handling in send() and in uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) - that all of the bytes were acknowledged; send.c knew that they were not. - -5.15 2010-12-12 Gregory Nutt - - * net/uip/uip_tcpaddsend.c and net/send.c: Another place where the TCP sequence - number problem "fixed" in 5.14 might occur. - * net/send.c: Check if the destination IP address is in the ARP table. If - not, then don't consider the packet sent. It won't be, an ARP packet will go - out instead. This improves behavior, for example, on the first GET request - from a browser. - * arch/arm/src/lpc17xx/lpc17_emacram.h and lpc17_allocateheap.c: The Ethernet - logic was using all of AHB SRAM Bank0 for Ethernet packet buffers (16K). An - option was added to limit the amount of SRAM used for packet buffering and to - re-use any extra Bank0 memory for heap. configs/olimex-lpc1766stk/nettest - now uses only 8K at the beginning of Bank0; the 8K at the end of Bank0 is - included in the heap - * arch/arm/src/lpc17xx/lpc17_ssp.c: Fix compilation errors when SSP1 is - selected. - * configs/olimex-lpc1766stk/nsh: Enable network and SD/MMC card support in - NSH. Networking and telnetd interface as well as SPI-based microSD are - now functional. - * examples/nsh/nsh_netinit.c: Fix NSH bug. If CONFIG_NET is selected, but - CONFIG_EXAMPLES_NSH_TELNETD is not selected, then the network is never - initialized and bad things happen if you try to ping. - * drivers/lcd: Add header files for the Phillips PCF8833 LCD controller and - for the Epson S1D15G10 LCD controller. A driver for the Nokia 6100 LCD is - coming. - * include/nuttx/spi.h and almost all other SPI files: Added an optional - cmddata() method to the SPI interface. Some devices require an additional - out-of-band bit to specify if the next word sent to the device is a command - or data. This is typical, for example, in "9-bit" displays where the 9th bit - is the CMD/DATA bit. The cmddata method provides selection of command or data. - * drivers/lcd/p14201.c: Now uses the cmddata() method of the SPI interface. - * arch/arm/src/lpc17xx/lpc17_usbdev.c: LPC17xx USB driver now appears to - to be fully functional. examples/usbstorage configuration verified (the - examples/usbserial configuration is untested). - * drivers/usbdev/usbserial.c and usbstorage.c: All USB class drivers need - to call DEV_CONNECT() when they are ready to be enumerated. That is, - (1) initially when bound to the USB driver, and (2) after a USB reset. - * drivers/lcd/nokia6100.c: A driver for the Nokia 6100 LCD. This driver - has not be verified as of the initial check-in. - * configs/olimex-lpc1766stk/nx: A NX graphics configuration for the Olimex - LPC1766-STK board using the Nokia 6100 LCD driver. This configuration has - not been verified as of the initial check-in. - * include/nuttx/spi.h: the SPI_SETBITS macro was calling the setmode method. - This is a very important bug-fix in some usages. - -5.16 2011-01-10 Gregory Nutt - - * include/nuttx/usb: Created new directory. Moved all usb-related header - files to this new directory. Created a skeleton for a new USB host header - file - * drivers/usbhost: Add USB host "registry" where connect devices can be - matched with the correct USB class driver. - * arc/arc/src/lpc17xx/lpc17_usbhost.c: Add a simple USB host driver for - the NXP lpc17xx. - * drivers/usbhost: Add generic USB device enumeration logic. - * drivers/usbhost: Add a USB host class driver for the (Bulk-Only) USB - Mass Storage Class. - -5.17 2011-01-19 Gregory Nutt - - * include/nuttx/usb: rename usb_storage.h to storage.h. - * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for low-speed devices. - * drivers/usbhost/usbhost_skeleton.c: Template for new class drivers - * include/nuttx/usb/hid.h and drivers/usbhost/usbhost_hidkbd.c: New - files for HID keyboard support. - * arch/arm/src/lpc17xx/lpc17_usbhost.c: Will now handle multiple - concurrent transfers on different endpoints (still only one TD per - endpoint). All methods are protected from re-entrancy; lots of re- - structuring in preparation for interrupt endpoint support. - * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for periodic - interrupt transfers. - * examples/hidkbd: Added a simple test for the USB host HID keyboard - class driver. - * configs/olimex-lpc1766stk/hidkbd: Added a configuration to build the - USB host HID keyboard class driver test for the LPC17xx. - * Ran the tool CppCheck (http://sourceforge.net/apps/mediawiki/cppcheck) and - fixed several errors in the code identified by the tool. - -5.18 2011-02-27 Gregory Nutt - - * Incorporate several uIP patches from http://gitweb.aeruder.net/?p=uip.git;a=summary. - - Lost SYNACK causes connection reset - - Fix missing UDP stats for sent/received packets - - Added support for Cygwin as development/test platform. - * configs/demo9s12ne64: Integrate new buildroot-1.9 m8s12x toolchain. - * 'uname -o' is used throughout the build logic in bash scripts and also in - Make.defs files in order to distinguish between Cygwin and Linux. However, - the -o option is not standard and is not supported under, for example, OS-X or - Solaris. This was solved by changing all 'uname -o' references to the more - complex: 'uname -o 2>/dev/null || echo "Other"' - * drivers/usbhost/usbhost_enumerate.c: Add logic to get the VID and PID. This - is necessary in order to support vendor-specific USB devices. - * examples/wlan, configs/olimex-lpc1766stk/wlan, drivers/usbhost/usbhost_rtl8187.c, - Add infrastructure to support RTL18187 wireless USB. - * configs/nucleus2g: backed out USB host changes... wrong board. - * Renamed arc/hc/include/mc9s12ne64 and src/mc9s12ne64 to m9s12. That name is - shorter and more general. - * The NuttX repository has been converted to SVN and can now be found here - http://svn.code.sf.net/p/nuttx/code/trunk/ - * configs/mbed/hidkbd: Added USB host support for the mbed LPC1768 board; add - a USB host HID keyboard configuraion. - * drivers/usbhost/hid_parser.c: Leverages the LUFA HID parser written by - Dean Camera. - * examples/nsh: Correct an usage of getopt(): If you stop calling getopt() - before all parameters are parsed, you can leave getopt() in a strange state. - * include/nuttx/video/fb.h: Restore missing RGB type that was accidentally removed - when Nokia 6100 support was added. - * Rename arch/pjrc-8051 to arch/8051 - * configs/ne64badge: Add a configuration for the Future Electronics Group - NE64 Badge development board (Freescale MC9S12NE64) - * Changes contributed by Uros Platise: - - Add support for the STM32F103RET6 - - configs/vsn: Support for the ISOTEL NetClamps VSN V1.2 ready2go sensor - network platform - * arch/hc, configs/ne64badge: Development is complete for the Freescale - mc9s12ne64 on the Future Electronics Group NE64 /PoE Badge board. Howeve, - this port remains untested until I figure out this BDM / Code Warrior - and paged build thing - * Added a new 'kill' command to NSH that will support sending signals to - running NuttX tasks. - -5.19 2011-03-12 Gregory Nutt - - * arch/arm/stm32/stm32_idle.c: During idle times, the STM32 now uses the - WFI instruction to sleep in a reduced power mode until the next interrupt - occurs (Contributed by Uros Platise). - * NSH: 'mem' command renamed to 'free'. Output is now more similar to the - Linux 'free' command. - * NSH: Correct a redirection bug in NSH. The following would not work; it - resulted in a hang after the 'cat /dev/fifo': - - nsh> mkfile /dev/fifo - nsh> cd /tmp # /tmp is a mounted RAM disk - nsh> cat /dev/fifo > test.txt & - nsh> echo "This is a test" > /dev/fifo - - The error was caused because (1) there was a path that resulted in stdout - being closed (the "hang") and also (2) the 'cat' command was always outputting - to stdout, not to the redirected file descriptor. Now: - - nsh> cat test.txt - This is a test - - * drivers/pipes/pipe_common.c: Driver open method was not returning an EINTR - error when it received a signal. Instead, it just re-started the wait. This - makes it impossible to kill a background pipe operation from NSH. - * include/stdint.h: Correct some errors in conditional compilation (submitted - by Johannes Hampel). - * arch/arm/lpc17xx/lpc17_idle.c: Uses the same logic as the STM32: uses the - WFI instruction to sleep in a reduced power mode until the next interrupt - occurs. - * configs/olimex-lpc1766stk: Added an LED encoded to indicate if the LPC1766 - is in sleeping. - * examples/mm: This is a simplified version of the "built-in" memory manager - test of mm/mm_test.c. It is simplified because it does not have access to - the internals of the memory manager as does mm/mm_test.c, but it has the - advantage that it runs in the actual NuttX tasking environment (the - mm/mm_test.c only runs in a PC simulation environment). - * drivers/mmcsd_sdio.c/h: Several corrections submitted by Uros Platise. - * arch/x86: Provide support for x86 architectures. Support for the i486 - architecture under QEMU is provided under arch/x86/include/i486, - arch/x86/include/qemu, arch/x86/src/i486, and arch/x86/src/qemu. - * configs/qemu-i486: "Board" support configurations for verifying the QEME - i486 port. - * arch/arm/src/stm32/stm32_spi.c: Correct base address of SPI3 (reported by - Uros Platise). - * drivers/mmcsd/mmcsd_sdio.c: Correct a loop termination condition (also - reported by Uros Platise). - * drivers/mtd/ramtron.c: Driver for SPI-based RAMTRON NVRAM devices FM25V10 - (and others). Contributed by Uros Platise. - * examples/nsh and tools/mkromfsimg.sh: Add support for platform-specific - ROMFS-based NSH start-up scripts. - * drivers/serial/uart_16550.c and include/nuttx/serial/uart_16550.h: Support - for a generic 16550 UART. - * configure/qemu-i486/nsh: QEMU NSH example. - * ../apps: The apps directory add-on was created by Uros Platise. It - supports a set of end-user applications than can be executed on top of - NSH. Think of it this way: In a buckled-up embedded application, your - end-user programs will probably have their own dedicated start-up logic. - But, during development, you might want to have you applications - available and executable from the NSH command line. This apps/ addon - (and NSH hooks) was contributed by Uros to accomplish just that. - * sched/sched_waitpid() and include/sys/wait.h: Provides a simple and - very incomplete implementation of waitpid(). waitpid() is only available - if CONFIG_SCHED_WAITPID is defined in your configuration file. - * sched/atexit.c and sched/exit.c: The atexit function is not frequently - used. In order to save a few bytes, it is now conditioned on - CONFIG_SCHED_ATEXIT. It your application is currently using atexit(), - you will need to add CONFIG_SCHED_ATEXIT to your configuration file. - * drivers/net/slip.c: Add a SLIP driver (untested on initial check-in). - * configs/olimex-lpc1766stk/slip-httpd: An example that uses SLIP to - provide a serial-port based THTTPD web server. - -6.0 2011-03-21 Gregory Nutt - - * lib/lib_fopen(): fopen() was not returning the correct errno value - when the underlying open() failed. - * include/net/uip/uip-arch.h: The uIP interface has been extended - slightly so that drivers can be concurrenly filling and sending - packet buffers. This capability was needed by the SLIP driver. - * drivers/net/slip.c: Several corrections and some re-design of - of the driver. - * apps/ChangeLog.txt: the apps/ directory now has its own ChangeLog. - * configs/vsn: - - IDLE LED blinking fix - - Added board power off function - * arch/arm/src/stm32/stm32_gpio.c and stm32_internal.h: Fixed - PullUp/Down Input Configuration. - * arch/arm/src/lpc17xx/lpc17_serial.h: Now supports Auto-RTS and - Auto-CTS modes. This is needed to support SLIP. - * drivers/net/slip.c: SLIP is now basically functional on the - LPC17xx with some caveats as described in the TODO list under - LPC17xx. - * arch/x86/include/i486/irq.h: Fix irqrestore() macro... it was not - correctly re-enabling interrupts. - * arch/x86/src: Fix numerous problems with i486/QEMU context - switching. Basically, the logic was missing the cases to handle - the differing stack frames when a priority change occurs and when - no priority change occurs. - * configs/qemu-i486/ostest and nsh: The QEMU i486 port is complete. - it now passes the OS test and supports the NuttShell (NSH). - * misc/drivers: Created a new directory to hold non-BSD licensed - drivers that may be added into NuttX via an installation script. - * drivers/usbhost/usbhost_rtl8187.c: A decision was made to - incorporate code taken from the Linux kernel. That changes the - licensing on this module to GPL. To avoid licensing contamination, - this driver was moved to misc/drivers/rtl8187x *prior* to adding - any of the GPL logic. There is an INSTALL.sh script at the location - where the GPL driver(s) can be re-installed into the NuttX source - tree. By re-installing the driver, you agree to the GPL licsensing - and all of its implications. - * Makefile, apps/Makefile, tools/configure.sh: Add logic to copy - configs///appdir to apps/.config and to simply the - application configuration logic. - * examples/nsh and apps/nshlib: Move the core NuttShell (NSH) logic - out of the exemples directory and into the apps/ directory where - it belongs. - * apps/Makefile and configs/*/appconfig: Use '=' as the delimiter - instead of '/' so that sub-directories in apps/ can be used. - * apps/vsn: Move all VSN apps to apps/vsn. - * nuttx/examples moved to apps/examples - -6.1 2011-04-11 Gregory Nutt - - * arch/arm/include/lpc17xx/irq.h and arch/arm/src/lpc17xx/lpc17_gpio*.c: - Fix several bugs in the GPIO interrupt logic. Submited by - Decio Renno. - * Initialization for the CONFIG_APPS_DIR is now supported during the - earlier, 'context' build phase. - * arch/arm/src/lpc17_gpioint.c: Finish coding of the LPC17xx GPIO - interrupt logic. - * net/netdev_unregister.c: Add capability to un-register a network - device. - * drivers/mmcsd/mmcsd_sdio.c: extra effort to correctly handle cases - without the SDcard (but one issue still exists in STM32) - * arch/arm/src/stm32/stm32_tim.*: Added basic timer support TIM1..TIM8 - with output PWMs and interrupt logic - * config/vsn/src: Added basic support for Sensor Interface (GPIO and - PWM Power Output, and the sif utility program) - * fs/: Reorgnize header so that file systems can be built outside - of the nuttx source tree - * apps/namedapp/binfs.c: Create a tiny filesystem that can be used - to show the internal named apps under /bin. - * fs/fs_opendir.c: Correct an error that occurs when a file system is - mounted in the root directory. This was discovered while mounting - the named app's /bin directory. - * lib/: Move all source files into a subdirectory of lib/ named after - the header file in which the library function is prototyped. - * sched/ and lib/pthread/: Move pthread attribute-related interfaces - from sched/ to lib/pthread where they more appropriately belong. - * sched/ and lib/semaphore/: Move some semaphore-related interfaces - from sched/ to lib/pthread where they more appropriately belong. - * syscall/: The beginnings of an optional syscall Kernel interface. - * tools/mksyscall.c: Add a tool that will auto-generate syscall proxies - and stubs from a comma-separated-value (CSV) data file. - * arch/arm/src/cortexm3/mpu.h: Add a header file describing the Cortex-M3 - MPU registers. - * Numerous modifications to the build system. Various people have reported - build problems since the re-organization and release of NuttX-6.0. I am - unable to replicate the build problems in my environment, but the changes - have be incorporated in hope of correcting the build issues in other - environments. - * drivers/i2c/st_lis331dl.c: I2C-based driver for the LIS331DL MEMS - motion sensor. Contributed by Uros Platise. - * Makefile: The NuttX build system will now supported building NuttX as two - separately linked images: (1) a kernel-mode RTOS image, and (2) a user- - mode application image that communicates to the RTOS kernel via system - calls. A lot more still must be done. - * user_initialize(): Eliminated the user_initialize() initialization hook. - It is difficult to maintain and redundant: Board level initialization - an up_initialize() provide the same kind of capability. - * arch/*/include/*/type.h: On some compilers, char defaults as unsigned. - Explicitly add signed to integer types if signed is what is required. - * arch/*: For all architectures -- Global register state save structure - (usually called g_current_regs) should be marked volatile; Added general - capability to support nested interrupts (not fully realized for all - architectures). - * sched/task_create.c: Add support for starting kernel-mode thread. - * drivers/usbdev/usbdev_serial.c: Fix reported by Sheref Younan. USB - was being reset after serial driver was closed. As a result, you could - no reopen the serial driver. - * configs/lpcxpresso-lpc1768: Add a board configuration for the Embedded - Artists LPCXpresso LPC1768 board. - -6.2 2011-05-06 Gregory Nutt - - * arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct errors in logic that maps - and IRQ number into a register bit number. - * Makefile: Fix an error introduced in the top-level Makefile in NuttX-6.1. - This error only shows up if you have a /tftpboot directory. Then the - make will fail with an obscure error about not being able to stat pass2. - * configs/lpcxpresso-lpc1768/nsh: Add an NSH configuration for the - LPCXpresso board. - * configs/*/ld.script: Removed 'sh_link not set for section .ARM.edix' for - a few of the builds. In you have this warning, it can be removed with the - following change to the ld.script file: - - + __exidx_start = ABSOLUTE(.); - .ARM.exidx : { - - __exidx_start = ABSOLUTE(.); - *(.ARM.exidx*) - - __exidx_end = ABSOLUTE(.); - } >sram - + __exidx_end = ABSOLUTE(.); - - * arch/arm/src/lpc17xx: Correct some typos/bugs in configuration of LPC17xx - UART2 and UART3. - * nuttx/clock.h: Replace all references to the global variable g_system_timer - with clock_systemtimer() (currently just a macro that that returns g_system_timer). - * lib/string/strrch.c: Would fail if the searched-for character were the first - character in the string. - * tools/version.sh and mkversion.c: Tools to manage a NuttX version number - file - * sched/clock_getutc() and lib/time/lib_time.c: Add support for 1 second UTC - interface. - * net/net_dup2.c and include/nuttx/net.h: The conditional compilation for - '#if CONFIG_NFILE_DESCRIPTOR > 0' was wrong in both of these files. It should - be '#if CONFIG_NFILE_DESCRIPTORS > 0'. This causes a dup2() failure in THTTPD - and a failure to get a CGI page. The consequence can be a very serious bug! - * configs/lpcxpresso-lpc1768/usbstorage, thttpd, and dhcpd: Add an USB storage, - THTTPD web server, and DHCP server configurations for the NXP LPCXpresso board. - * drivers/lcd/ug-9664hswag01.c and ssd1305.h: Add support for Univision UG-9664HSWAG01 - OLED with Solomon Systech SD1305 LCD controller. - * configs/lpcxpresso-lpc1668/nx: Add a NX graphics configuration for the LPCXPRESO - board. - * graphics/nxglib/nxglib_nonintersecting.c: Fix some single bit errors in - calculation of non-intersecting regions. This was causing an anomaly - in examples/nx in column 0. - * drivers/mtd/rammtd.c: Added a RAM based MTD driver. This RAM driver simulates - FLASH and is useful for testing purposes. - * arch/arm/src/arm/up_head.S: Fix backward conditional compilation. This cause - the configs/mx1ads configuration to fail to build but does not appear to affect - any other ARM9 build. - * fs/nxffs: Adding a tiny, wear-leveling FLASH file system for NuttX. This - file system is intended to be small and will have some limitations. The - implementation is incomplete on initial checkin. - * apps/examples/nxffs and configs/sim/nxffs: Add a test a a configuration that - will be used to verify NXFFS. - * fs/fat/fs_fat32.c and fs_fat32util.c: Incorpated two bugs with fixed provided - by Sheref Younan. Thanks! - * fs/nxffs: After a couple of weeks of testing and bug fixes, NXFSS appears - stable and functional. - -6.3 2011-05-15 Gregory Nutt - - * Remove clock_getutc(). It is replaces with clock_gettime(CLOCK_ACTIVETIME). - Add other RTC related changes provided by Uros Platise. - * arch/arm/src/stm32/stm32_flash.c: Add support for access to on-chip STM32 - FLASH; beginning of integration with NXFFS (Uros Platise). - * arch/mips: Added directory structure for PIC32 support - * configs/pcblogic-pic32mx: Add directory structure for PCB Logic PIC32MX board - * apps/include: Move include/apps to apps/include. A symbolic link is created at - build time - * Makefile: Removed support for Pascal pcode interpreter. Support for that - interpreter has been moved to apps/interpreter/Makefile. - * tools/mkdep.sh: Should not report an error if there are no files on the command - line. This happens normally in certain configurations. - * drivers/usbhost: Sheref Younan reported an error in the error handling when - connection to a USB device fails. In certain fail cases, the logic would try - to free the device class instance twice, the first was okay, but the second - caused a crash. - * graphics/nxbe/nxbe_colormap.c: Fix error noted by Bassem Fahmy. The function - nxbe_colormap was change to nxbe_configure... apparently "search-and-replace" - error. This error was not noticed before because most NX platforms do not use - colormapping. - * arch/rgmp and configs/rgmp. Add architecture support and build - configuration for RGMP. RGMP is a project for running GPOS and - RTOS simultaneously on multi-processor platforms. See - http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further - information about RGMP. - * lib/stdio/lib_fclose.c: Must flush all buffered data when the file is closed. - Instead, it was discarding the buffered data. - * lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER. - If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this - option may be added to force automatic, line-oriented flushing the output buffer - for putc(), fputc(), putchar(), puts(), fputs(), printf(), fprintf(), and vfprintf(). - When a newline is encountered in the output string, the output buffer will be - flushed. This (slightly) increases the NuttX footprint but supports the kind of - behavior that people expect for printf. - -6.4 2011-06-06 Gregory Nutt - - * lib/drivers/cc1101: Add initial, functional CC1101 wireless driver - (contributed by Uros Platise) - * arch/mips and configs/pcblogic-pic32mx: The MicroChip PIC32MX port is now - code complete and ready to begin testing. Unfortunately, it looks like - testing will be delayed due to tool issues (My PICkit 2 will not work the - the MPLAB debugger on PIC32; I will need to get a PICkit 3). - * drivers/net/e1000.c/h: A PCI-based E1000 Ethernet driver submitted - by Yu Qiang. - * lib/net/lib_inetaddr.c: An implementation of the inet_addr() function - submitted by Yu Qiang. - * arch/arm/src/lpc31xx and arch/arm/include/lpc31xx: Renamed from lpc313x - to make name space for other famiy members. - * arch/arm/*/lpc31xx: Added support for the LPC315x family (untested). - * sched/task_exithook.c: Functionality performed when a task exits or is - deleted has been moved to a common file task_exithook.c. Now exit() - functionality (like flushing I/O and calling registered atexit() - functions, etc.) will be performed when a task is deleted as well. - * mm/: Added support for CONFIG_MM_SMALL. Each memory allocation has a - small allocation overhead. The size of that overhead is normally - determined by the "width" of the address support by the MCU. MCUs - that support 16-bit addressability have smaller overhead than devices - that support 32-bit addressability. However, there are many MCUs - that support 32-bit addressability *but* have internal SRAM of size - less than or equal to 64K. In this case, CONFIG_MM_SMALL can be - defined so that those MCUs will also benefit from the smaller, 16- - bit-based allocation overhead. - * lib/string/lib_strndup.c: Add standard strndup() library function. - * net/getsockname.c: Added standard getsockname() to return the local - address associated with a socket. - * lib/stdio/lib_asprintf.c: Add asprintf() - * configs/olimex-lpc1766stk/ftpc: Add a configuration to support - testing of the FTP client shell. - * fd/fs_fdopen.c and net/net_checksd.c: Add support so that fdopen may - be used with socket descriptors. - * net/recvfrom.c: Fix an error found in receiving small files via FTP: - The small file is received a buffered in the readahead buffer, then the - socket is disconnected. When the app calls recvfrom, the socket is - already disconnected and the buffered data is stranded. Now, recvfrom - will continue to return success after the socket is disconnected until - the readahead buffer is drained. - * olimex-lp1766stk/ftpc/defconfig: Many configurations have the MTU - (CONFIG_NET_BUFSIZE) set to very small numbers, less then the minimum - MTU size that must be supported -- 576. This can cause problems in - some networks: CONFIG_NET_BUFSIZE should be set to at least 576 in - all defconfig files. This has only been fixed in this defconfig file. - -6.5 2011-06-21 Gregory Nutt - - * arch/avr/src/avr and arch/avr/include/avr: Adds general support for - the Atmel 8-bit AVR family. - * arch/avr/src/atmega and arch/avr/include/atmega: Adds support for the - Atmel AVR ATMega family. - * arch/avr/src/at90usb and arch/avr/include/at90usb: Adds support for the - Atmel AVR AT90USB family. - * configs/micropendous3: Adds a board configuration for the Opendous - Micropendous 3 board. This board may be populated with several different - members of the Atmel AVR AT90USB family. - * configs/amber: This is a placehold for the Atmel ATMega128 Amber Web - Server from SoC Robotics. Not much present in this directory on initial - check-in. - * configs/teensy: Adds a board configuration for the PJRC Teensy++ 2.0 board - that features an Atmel AT90USB1286 MCU. - * fs/fat: Offsets, sector numbers, etc. need to be off_t, not size_t. size_t - is intended to be the maximum size of a memory object, not a file offset. This - does not make any difference except on systems (like the AVR) where size_t - is only 16-bits. - -6.6 2011-07-11 Gregory Nutt - - * drivers/mtd/ramtron.c, net/net_checksd.c, fs/fs_fdopen.c, and include/nuttx/mii.h: - Several structural changes made to get a clean compile under the eZ80 ZDS-II - toolchain (no design changes). - * drivers/usbhost/usbhost_storage.c: Incorpated bugfixes reported by Sheref H. - Younan: (1) Read capacity logic read largest block, not the number of blocks - and was, therefore, off by one, and (2) Some devices stall of get Max LUN request - if they support only a single LUN. Logic now assumes a single LUN if the get - Max LUN request fails. - * include/nuttx/arch.h, lib/stdio/lib_libvsprintf.c, lib/stdio/lib_fputs.c: Add - a new configuration option to support extracting strings from FLASH or EEPROM - or other memories where the string data cannot be accessed by simply de-referencing - a string pointer. - * arch/sim/src/up_romgetc.c: Used to test the basic logic to access strings - without directly de-referencing a string pointer. - * arch/avr/src/avr/up_romget.c: Used to access strings that lie in the first - 64K of FLASH (But I still haven't figured out how to get strings to reside in - FLASH without using the PROGMEM attribute). - * configs/teensy/src/up_spi.c: Correct reading of SD CD and WP pins (was reading - the wrong register. AVR SPI now appears to be functional. - * arch/avr/src/at90usb/at90usb_usbdev.c: Correct USB initialization. Interrupts - were being enabled BEFORE the interrupt handler was attached. - * configs/sure-pic32mx: Add a configuration for the Sure Electronics, "Advanced USB - Storage Demo Board," Model DB-DP11215 (http://www.sureelectronics.net/goods.php?id=1168). - This board features the MicroChip PIC32MX440F512H MCU. (Untested on initial - check-in). - * configs/stm3210e-eval/nsh2: Add another NSH configuration for the STM32 with - some different properties. - * CONFIG_NSH_CONDEV: Add a configuration option to allow using a different character - device (such a a different UART) for the NSH interface. This allows, for example, - debug output to come from the console device while using another device for NSH. - There are some issues on initial check-in: NuttX doesn't have termios and the - console device has special properties that make using NSH awkward. Examples: - No CR-LF expansion, no character echoing, no command line editting. - * arch/arm/src/stm32/stm32_lowputc.c and stm32_serial.c. Correct several bugs - involving serial port configuration. These bugs are only critical if you - are trying to using multiple UARTs on STM32. - * configs/stm3210e-eval/src/up_lcd.c: Add a driver for the STM3210E-EVAL's LCD. - * configs/stm3210e-eval/nx: Add NX configuration for the STM3210E-EVAL. - * configs/nuttx/arch.h (and arch/arm/src/stm32, configs/*/src/up_buttons.c): - Standardize interfaces exported for button support and button interrupts. - * configs/stm3210e-eval/src/up_buttons.c: Add interrupting button support. - Also fixes a few errors in STM3210E-EVAL button decoding. - * configs/stm3210e-eval/buttons: Add a configuration to exercise STM3210E-EVAL - buttons. - * arch/arm/src/stm32/stm32_gpio.c: GPIO interrupt handling for pin - numbers were being aliased: 5-9 together and 10-15 together. Extended - the logic to peform decoding of GPIO interrupts and unique dispatching - for all 16 pins. - * configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext - example. This example focuses on placing text on the background while - pop-up windows occur. Text should continue to update normally with or without - the popup windows present. - * arch/arm/src/common/up_checkstack.c: ARM stack overflow checking submitted - by Hal Glenn. - * arch/arm/src/lpc17xx: Changes to compile successfully with no serial console - (also submitted by Hal Glenn). - * graphics/nxfonts/nxfonts_convert.c: Fixed a critical bug that caused - when renderer some fonts with bits-per-pixel > 8 - * graphics/nxbe/nxbe_move.c: Fixed an error in the graphics move logic (This - was a previously untested interface). Basically, there is some confusion - between use of (x,y) as a relative offset or as an absolute position. - * graphics/nxbe/nxbe_close.c: Fixed an important graphics system bug: - When a window is closed, the display was not being updated. The old - window graphic was left on the display for a time. - -6.7 2011-08-02 Gregory Nutt - - * Makefile: Added a export target that will bundle up all of the NuttX - libraries, header files, and the startup object into an export-able - tarball. - * arch/arm/src/lpc17xx/lpc17_can.h: Correct some typos in the CAN - register definitions. - * drivers/serial/serialirq.c: Correct an error that can occur if the - serial RX buffer becomes full. Data is now discarded in that case; - before, leaving data in the hardware would cause infinite interrupts - one most MCUs since you must read the data in order to clear the - interrupt. - * arch/arm/src/lpc17xx/lpc17_can.c: Added a CAN driver contributed by - Li Zhuoyi (Lzyy). - * include/stddefs.h and sys/types: Added type wchar_t. - * fs/fat/fat_fat32dirent.c: Move all FAT directory operations to this - new file; Implement VFAT long file name support. - * fs/fat/fat_fat32dirent.c: The configuration CONFIG_FAT_LCNAMES has - been around for some time but never tested until now. This setting - will mimic the NT 8.3 file name behavior: File names or extensions - may be all upper or all lower case (but not mixed). If - CONFIG_FAT_LCNAMES is not selected, all filenames are strictly upper - case. - * configs/stm3210e-eval/nsh2: Console is back on UART1; Added - examples/nx as an NSH "built-in" command as a demonstration. - * fs/fat/fs_fat32dirent.c: Fix an important bug in the directory - allocation (fat_allocatedirentry()). I looks like it could be - initializing the wrong sectors! NOTE: This function was in - fs_fat32utils.c in earlier releases. - * arch/arm/src/stm32_sdio.c: Correct an important DMA-related bug; - SDIO transfer completion events and DMA completion eventes were - not being coordinated correctly. - * configs/stm3210e-eval/nsh2: Enable FAT long file name support - * sched/sem_timedwait.c: Add the standard sem_timedwait() interface. - * graphics/nxfonts/nxfonts_getfont.c, nxfonts_bitmap.c, - Makefile.source, and include/nuttx/nxfonts.h: Support for multiple - fonts included. A new interface, nxf_getfonthandle() takes a font - ID and returns a handle that is now used at all other font interfaces - to specify which of the multiple fonts to use. - * arch/arm/src/lpc17xx/lpc17_syscon.h: Fix typo (reported by Li Zhuoyi). - * configs/stm3210e-eval/nsh2: Extended to support two new commands: - 'msconn' will connect the USB mass storage device; 'msdis' will - disconnect the USB storage device. - * tools/bdf-converter.c. This C file is used to build the bdf-converter - program. The bdf-converter program be used to convert fonts in Bitmap - Distribution Format (BDF) into fonts that can be used in the NX graphics - system. - * include/nuttx/nx: Move all NX header files from include/nuttx to - include/nuttx/nx. - * drivers/usbdev/usbdev_usbstorage.c and arch/arm/src/stm32/stm32_usbdev.c: - Correct a memory leak when the USB mass storage driver is connected and - then disconnected from the target. The write requests were not being - freed. NOTE that the unregister logic in the STM32 needed to call - stm32_reset() in order to return the write requests to the USB mass - storage driver; it is possible that a similar but could exist for other - architectures. - * graphics/nxfonts/nxfonts_*.h: Add serveral more new fonts - * arch/z80/src/eZ80/ez80_serial.c: Fix some errors in serial driver - setup for UART1 (submitted by Paul Osmialowski). - * drivers/input/tsc2007.c and include/nuttx/input/*: Add a generic NuttX - touchscreen interface. Add a driver for the TI TSC2007 touchscreen - controller. - * graphics/nxglib/lcd and fb: Add low level routines to set single pixels. - * lib/math/lib_b16atan2.c: Add a fixed precision atan2() function - * graphics/nxglib/nxglib_splitline.c: Add logic to divide a wide line into - trapezoidal components. - * graphics/nxmu/nx_drawline.c, graphics/nxsu/nx_drawline.c, - graphics/nxtk/nxtk_drawlinewindow.c, graphics/nxtk/nxtk_drawlinetoolbar.c: - Add new line drawing interfaces (untested). - -6.8 2011-08-19 Gregory Nutt - - * arch/arm/src/lpc17xx/chip.h: Fix some chip memory configuration errors - for the LPC1764, LPC1756, and LPC1754 (submitted by Li Zhuoy (Lzyy)) - * arch/arm/src/lpc17xx/lpc17_can.h: Revised CAN driver submitted by - Li Zhuoy (Lzyy). The driver now supports both CAN1 and CAN2. - * arch/arm/sim/up_lcd.c: Add a simulated LCD driver. - * configs/stm3210e-eval/nxlines: Added a configuration to build - examples/nxlines. - * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX - trapezoid drawing functions and (wide) line drawing functions. - * arch/rgmp and configs/rgmp. Yu Qiang has ported RGMP to the OMAP4430 (arm) - pandaboard and release the new RGMP 0.3 version. The main changes are: (1) - Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and - (2) Extract architecture dependent code in arch/rgmp/include and - arch/rgmp/src into corresponding x86/ and arm/ directories. - * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstick-k40: - Add a directory structure to support the port to the Kinetis KwikStik-K40. - There is no real substance in the initial check-in; only the directory - structure and skeleton files (Code complete on 8/15/11). - * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3 - directories and files to armv7-m; Change name of of all CORTEXM3 constants - to ARMV7M. This is a major namespace change needed to cleanly support the - ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M). - * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c. Fixed several - critical bugs related to signal handling initialization and for signals - the wake up tasks that are waiting to send or receive message queues. In - the first two files, errors would prevent proper allocation of signal-related - structures from interrupt handlers. In the second, there was missing - "clean-up" logic after a signal occurred, leaving the message queue in - a bad state and resulting in PANICs. All are important. (submitted by - hkwilton). - * arch/arm/src/kinetis: Added header files defining all Kinetis registers - and bit fields within all Kinetis registers. - * configs/twr-k60n512: Add support for the Kinetis K60 Tower board - (TWR-K60N512). - * drivers/can.c: Fixed a semaphore overflow problem in the CAN driver - (reported by Li Zhouy (Lzyy)). - * 8/18/2011: The basic port to the FreeScale Kinetis TWR-K60N512 board is - now functional. - * configs/twr-k60n512: Add Kinetis TWR-K60N512 NSH configuration. - * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure - and TI ADS1255 driver developed and submitted by Li Zhouy (Lzyy)). - * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c: Add logic to - multiplex usage of the GPIO pins (contributed by Uros Platise). - * configs/twr-k60n512/nsh: Added and verified a NuttShell (NSH) - configuration for the Freescale, Kinetis TWR-K60N512 board. - -6.9 2011-09-11 Gregory Nutt - - * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts. - Initially check-in is just a crude port of the STM32 SDIO driver. - Much more work is needed. - * graphics/, include/nuttx/nx: Add new NX interfaces for drawing - circles -- both circular outlines and filled circles. - * graphic/nxglib/nxglib_spitline.c: Add a "fudge factor" that eliminates - some problems for rendering nearly horizontal, wide lines. Hmm... - but I suspect this fudge factor also leads to new problems rendering - very thin, nearly horizontal lines. More tuning is needed. - * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx: (1) Add - updates to the ADS1255 driver, (2) fix errors from my last merge (sorry), - (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add - LPC17xx ADC and DAC drivers. All contributed by Li Zhuoyi (Lzyy). - * tools/mkexport.sh: Extended the script that implements the top-level - 'make export' logic. The script now also finds and bundles up all of - the architecture-specific header files as well. - * drivers/arch/arm/src/stm32/stm32_i2c.c: Add a reset to the I2C - initialization logic to prevent spurious interrupts when the I2C - interrupts are enabled (submitted by Uros Platise). - * Scripts/makefiles/documents. Several adjustments, corrections and - typo fixes so that NuttX will build correctly on FreeBSD using the - ASH shell (submitted by Kurt Lidl). - * drivers/mtd/flash_eraseall.c: Add a callable function that accepts - the path to a block driver and then erases the underlying FLASH memory - (assuming that the block driver is an MTD driver wrapped in the FTL - layer). Hmmm... this is probably not the best long term solution; - flash_eraseall() should be a user-callable function that operates - one driver interfaces; not an internal, OS function that operates - on directly on block drivers. - * drivers/bch: Fixed some important bugs in the BCH driver (noted by - Li Zhuoyi (Lzyy)). This would have effected any large reads or writes - (larger than the hardware sector size). - * arch/*/src/Makefile: Use of -print-libgcc-file-name to get path to - libgcc.a may select the wrong libgcc.a if a multilib toolchain (like - CodeSourcery) is used. This can be a serious problem and can cause - crashes on Cortex-M3 if the ARM libgcc is used, for example. The fix - is to include ARCHCPUFLAGS on the gcc command line when asking it to - -print-libgcc-file-name. - * lib/time/lib_gmtimer.c: Correct several calculations that could lead - to errors in dates. - * drivers/pm: Add the beginnings of a NuttX power management sub-system. - * arch/arm/src/stm32/stm32_irq.c: Fix a error introduced in 6.8. - Timeout calculation uses clock_settime() instead of clock_gettime(). - Pretty gross error, but actually it works with the side effect of setting - a bad time. - * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by - Li Zhuoyi (Lzyy). - * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family - submitted by Li Zhuoyi (Lzyy) - * arch/arm/src/stm32_i2c.c: Correct two issues with the STM32 I2C driver: - (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings - need some additional bits; and (2) Correct a hang that will occur on - I2C1 if FSMC is also enabled. - * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h: Add an LM-75 - temperature sensor driver. - * configs/stm3210e-eval/src/up_lm75.c: Add support for the LM-75 on the - STMicro STM3210E-EVAL board. - * sched/clock_gettime.c: Correct an error in the tv_nsec calculation - that happens only config CONFIG_RTC is enabled. - * arch/arm/src/stm32/stm32_i2c.c: Correct some bugs related to waiting - for the I2C STOP condition to be cleared. - -6.10 2011-10-06 Gregory Nutt - - * lib/stdio/lib_fopen.c: Fix an error in fopen(); the file pointer was not - being positioned at the end of the file when the "a" and "a+" modes are - used. There are other issues with the "a+" modes (see the top-level TODO - list). - * drivers/usbdev/cdc_serial.c and include/nuttx/usb/cdc.h and cdc_serial.h: - Add support for the CDC ACM serial device class. - * fs/fat/fs_fat32.c: Fix a critical bug in the write logic: It a tiny write - cross a sector boundary, then two sector writes will occur. The first part - in the first sector may be written to the wrong sector number. - * fs/fat/fs_fat32util.c: Fix a stray write into the FAT (always sector 964 on - FAT32). This bug will cause some lost chains. I'm sure this bug could - corrupt files but at present, the only thing I have seen is that before - fixing this bug, the Windows chkdsk utility would report these lost chains. - * arch/arm/src/stm32/stm32_i2c.c: Driver can now operate in a faster polled - mode (at the expense of using more cpu cycles). - * arch/arm/src/stm32/stm32_i2c.c: Add trace debug capability. Enabled with - CONFIG_I2C_TRACE. - * arch/arm/src/stm32/stm32_i2c.c: Fix another bug where I2C conflicts with FSMC - being enabled. That time at the tail end of the transaction where there is - an unfinished stop condition. - * sched/mq_timedreceive.c and sched/mq_timedsend.c: The count of threads - waiting on the message queues was not being decremented after a timeout. - This would cause the accounting logic to become out of sync and the, perhaps, - an assertion to be triggered. This is an important bug and fixes a - potential crash when using mq_timedreceived() and mq_timedsend(). - * sched/mq_sndinternal.c: Related to the above, the send logic was incrementing - the wrong counter when it waited as part of the mq_timedsend.c logic. - * fs/fat: Fix an error in the long file name logic: If the long file name - is an even multiple of 13 bytes in length, then it should not include a - NULL terminating character. Fix contributed by Kaushal Parikh. - * configs/sim/nx11: Created a separate configuration to build the NX - example using the a simulated framebuffer driver on an X11 window. This - example has been verified on Ubuntu 9.09 (it does not work on Cygwin). - * arch/sim/src/up_touchscreen.c and up_x11eventloop.c: Adds support for a - simulated NuttX touchscreen device using mouse/pointer feedback from an - x11 window. - * configs/sim/touchscreen: Adds a configuration to verify the simulated - touchscreen driver (Does not work on Cygwin). - * configs/sam3u/touchscreen: This is the configuration that I plan to use - to verify the SAM3U-EK touchscreen driver. However, as of this writing, - there is no touchscreen driver for the board. - * CONFIG_RTC_HIRES: Add an option to support either a high-resolution RTC - that completely replaces the system timer tick but may overflow and lose - time when the MCU is off and also for a low-resolution (1 sec/tick) RTC - that can run until 2106 with no overflow. But in this latter case, higher - resolution time must come from the system timer. - * CONFIG_SYSTEM_UTC: Removed support for the UTC system timer. It just - doesn't do enough to be worth the CPU cycles or the complexity. - * CONFIG_SYSTEM_TIME16: Added support for an optional 64-bit system timer. - * fs/fat/fs_fat32util.c: Add support for FAT date/time stamps; Enabled via - CONFIG_FS_FATTIME. - * arch/arm/src/sam3u/sam3u_spi.c: Add an SPI driver for the AT91SAM3U. - * drivers/input/ads7843e.c and include/nuttx/input/ads7843e.h: Add a - driver for the TI ADS7843E touchscreen controller. - * fs/nxffs/nxffs_open.c: Fix an error when a file is open for writing; since - the file will get deleted it is already exists, there must be a check if - there are other open references to the file. - * arch/arm/src/stm32/stm32_sdio.c: Fixed an error where during SDHC - initialization interrupts were not being re-enabled. Caused more subtle - errors than you would think. - * arch/arm/src/stm32/stm32_i2c.c: Fixed an error where I2C timeouts appeared - to be successful transfers. - * configs/sim/nsh2: Add another simulated NSH configuration. This one - supports X11 graphics, C++, and exercises graphic functions as built-in - commands. - -6.11 2011-11-12 Gregory Nutt - - * arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not - selected. Doing so will cause errors if other configuration dependencies - are not met. - * configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD - do not work with R61580 LCD. - * configs/pic32-starterkit: Beginning of a configuration for the Microchip - PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this - with no serial port?! - * lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it - closes a read-only file. This is because it calls flush() which will - fail on read-only files. No harm is done other that a bad value is - returned. - * arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old - libboard.a was not being cleaned. - * arch/mips/src/pic32mx/pic32mx-gpio*.c: Add GPIO support for the PIC32MX. - * configs/sure-pic32mx/src/up_leds.c and up_buttons.c: Add button and LED - support for the Sure Electronics PIC32MX board. - * configs/ea3152: Add a configuration for the Embedded Artists LPC3152 - daughter board (with the same base-board used with configs/ea3131) - * graphics/nxmu/nx_getrectangle.c, graphics/nxsu/nx_getrectangle.c, - graphics/mxtk/nx_getwindow.c, graphics/nxmu/nx_gettoobar.c: New - interfaces to read from graphics memory - * graphics/nxbe/nxbe_bitmap.c: Fix an error in the error handling that - can cause valid bitmaps to fail to render. - * include/nuttx/video/rgbcolors.h: Fix errors in some 16- and 8-bit color - conversion macros. - * tools/incdir.sh: Fix issues when g++ is used as the compiler.

This is a rare case - if the block size is large, but can be common for tiny block sizes - and results in a crash and file system corruption. - * fs/nxffs/nxffs_initialize.c: Fix an initialize error. If the FLASH - is full on power-up, NXFFS will fail to initialize correctly. - * fs/nxffs/nxffs_write.c and nxffs_pack.c: Fix an error that can occur - when attempt to write to FLASH volume that is completely full but - has no value inodes on it. - * drivers/mtd/at24xx.c: Now supports a configurable block size that - supports using "clusters" of AT24 pages as blocks. This allows bigger - block sizes and more efficient use of EEPROM when the AT24 is used to - support a file system (such as NXFFS). (Contributed by Hal Glenn). - * include/nuttx/video/rgbcolors.h: More fixes to RGB color conversion - macros. - * arch/arm/src/common/up_createstack.c and up_usestack.c: For ARM EABI - the stack must be aligned to 8-byte boundaries. This is necessary for - passing aligned floating point values under EABI. Fix contributed by - David Sidrane. - * Numerous changes and fixes to the PIC32 interrupt handing logic. The - PIC32 port is almost complete but still not ready for prime time. - -6.12 2011-12-06 Gregory Nutt - - * fs/fat/fs_fat32util.c and fs_fat32.h: Logic extended to look in up to - four partitions for a valid FAT file system. - * drivers/input/tsc2007.c: Add support for 8-bit conversions; make sure - that A/D converters are active before requesting conversions. - * drivers/mmcsd0/mmcsd_sdio.c: Increase capacity variable from size_t - to uin64_t (if available) so that SD cards with capacities greater - than 4Gb can be supported. - * fs/fat/fs_fat32dirent.c: The root directory structure is different - from other directories. When formatted by Windows, it is not initialized - at all. Some additional special handling is required to initialize the - root directory entry to interoperate correctly with windows. - * fs/fat/fs_fat32util.c: In fat_systime2fattime(void) should be - clock_gettime() and not clock_gettime(). Also, there is a place where - FAT date is used instead of FAT time.

The initial check-in is little more than a framework for the driver. - * arch/arm/src/stm32/stm32_usbdev.c: Corrected two CRITICAL errors in the USB - device-side driver: (1) Handling of data overrun condition was wrong. When - there was no further memory to accept further OUT endpoint data, the driver - would hang with infinite interrupts; (2) the logic in setting toggle bits - was not correct. However, this driver has functioned for a long time until - the particular condition that revealed the bug occurred. My impression is - that this latter bugfix also fixes some STM32 USB performance problems. - * configs/hymini-stm32v: A configuration for the HY-Mini STM32v board contributed - by Laurent Latil. These changes also include support for the STM32F103VCT6. - * arch/configs/stm3240g-eval/src/up_pwm.c: Add hooks needed to use the new - apps/examples/pwm test of the STM32 PWM driver. - * drivers/mtd/mp25x.c: Add ability to use different SPI modes and different - manufacturers codes.

The new interfaces are moved into - nuttx/net.h which already has similar logic. - * include/nuttx/usb/usb.h: Can't use 'class' as a field name in USB structures. - This upsets C++ if usb.h is included. 'class' -> 'classid' in this header - file and all places that referenced 'class' - * drivers/usbdev/usbmsc.c: Fixed some backward conditional compilation. - * sched/on_exit.c: Add support for the on_exit() function., - * sched/exit.c, task_exithook.c, task_delete.c, sched_releasetcb.c: Move - the logic that closes file descriptors sooner in the task shutdown sequence. - When drivers are closed, they may need to do things that require a fully - up-and-running task. Some things cannot be done later when the task is - crippled. - * lib/dirent: Moved readdir_r() and telldir() from lib/misc to this new - directory where they belong. - * lib/termios. Implemented tcsetattr() and tcgetattr(). - * lib/stdio/lib_fgets.c: The old fgets includes some terminal related - functionality: It handles VT-100 commands, includes a command line editor - and echo characters back to the terminal. This old, overloaded fgets() - was renamed readline() and moved to apps/system/readline. The version - of fgets() in lib/stdio was them simplified and stripped down so that it - *only* gets a string -- as its description implies. - * arch/arm/src/lpc214x/lpc214x_usbdev.c: Add corrections suggested by - David Hewson many, many months ago. - * configs/mcu123-lpc214x/composite and configs/mcu123-lpc214x/src/up_composite.c: - Add a configuration to test the USB composite device. - * configs/stm3240g-eval/Telnetd: Add a configuration for testing the - Telnet daemon. - * configs/stm3240g-eval/nsh2: This is another NSH configuration. It differs - from the original nsh configuration because it does not have an RS-232 - console (only a Telnet console) and SDIO is enabled. This configuration is - required because the STM3240G-EVAL board cannot simultaneously support - RS-232 and SDIO due to pin conflicts. - * lib/string/lib_strcasestr.c: Add strcasestr(). - * lib/stdio/lib_avsprintf.c: Add avsprintf(). - * lib/net/lib_inetntop.c: Add inet_ntop(). - * lib/net/lib_inetpton.c: Add inet_pton(). - * include/pthread.h: Correct PTHREAD_MUTEX_INITIALIZER. - * fs/fat/fs_fatfs.c: Fix an error in the FAT statfs() implementation that - was causing some block counts to be reported incorrectly (reported by - David Sidrane). - * drivers/ramlog.c: Add a character driver that can substitute - for /dev/console and or be used for logging debug output when there - is no serial port available (such as when a Telnet console is used). - * lib/stdio/lib_syslogstream: Add a stream object that will be used to - re-direct all debug output to the RAM log if CONFIG_SYSLOG and - CONFIG_RAMLOG_SYSLOG are defined. - * lib/misc/lib_dbg.c: Add an interface enabled with CONFIG_DEBUG_ENABLE that - can be used to turn debug output on and off. - -6.16 2012-03-10 Gregory Nutt - - * drivers/sensors/qencoder.c and include/nuttx/sensors/qencoder.h: Add an - implementation for a quadrature encoder upper half driver. - * arch/arm/src/stm32/stm32_qencoder.c/.h: Add a initial implementation of - a lower-half quadrature encoder driver for the STM32. On initial check-in, - this is little more than a "skeleton" file. - * Various files: CAN ISO-11783 support contributed by Gary Teravskis. - * net/recv.c and net/recvfrom.c: Correct a bug in return value: The the peer - gracefully closes the connections, needs to return zero and not ENOTCONN. - * arch/arm/src/stm32/stm32_eth.c: Fix an error in the STM32 ethernet driver. - The received buffer size must be two bytes larger to account for the two byte - checksum that is appended to the packet. Otherwise, the last two bytes of - real data in the packet will get clobbered. - * arch/arm/src/stm32f40xx_dma.c: The STM32 F4 DMA has (finally) been verified - * arch/arm/src/stm32_sdio.c: STM32 F4 SDIO DMA is now supported - * configs/stm3240g-eval/nsh/defconfig: This configuration now supports SDIO - with DMA (see configs/stm3240g-eval/README.txt for some issues). - * arch/arm/src/armv7-m/up_vectors.S and arch/arm/src/armv7-m/up_vectors.S: New, - streamlined Cortex-M exception handling (with FPU supported). Contributed byh - Mike Smith - * net/accept.c, connect.c,and net_monitor.c: Correct an error in the accept - logic. After a new connection is made via accept(), monitoring for losses - of TCP connection must be set up (just as with connect()). The new file - net_monitor.c holds the common TCP connection monitoring logic used by both - the accecpt() and connect() logic. Contributed by Max Nekludov. - * net/recvfrom.c and net/uip/uip_tcpcallback.c: Fix a leak in the TCP - read-ahead logic. This is a *critical* bug fix! - * net/uip/uip_tcpinput.c: Correct an error in the TCP stack. It was - incrementing the received sequence number BEFORE determining if the - incoming data could be handled. If the data was dropped (usually because - there is insufficient buffering space), then no ACK will be sent and the - sequence number will be wrong. The end consequence of the bad sequence - number was that the when the dropped packet was re-transmitted, it was - was ignored because its sequence number looked wrong. Fix was, obviously, - to only increment the recevied sequence number if the TCP data was - accepted. - * configs/stm3240g-eval, configs/stm32f40discovery, and arch/*/src/Makefile: - Add changes to support building with the Atollic "Lite" toolchain. - * fs/fs_select.c: Correct select(), in the case of loss of network - connection (POLLHUP), select() must report a read-ready event. This - is how the standard select() interface is supposed to work: In the case - of loss-of-connection, select() reports read-ready. The next time you - read from the socket, you detect the end-of-connection event. Change - submitted by Max Nekludov. - * arch/arm/src/armv7-m/up_fpu.S and arch/arm/src/stm32/stm32_vectors.S: Fix - lazy FPU register saving with CONFIG_ARCH_FPU is set in the configuration. - * arch/arm/src/armv7-m: Lazy saving of floating point registers on context - switches now seems to be functional. - * net/uip/uip_tcpinput.c: Fix a TCP protocol error reported by Max Nekludov. - * configs/stm3240g-eval, configs/stm32f40discovery: Add changes to support - building with the Atollic "Pro" toolchain. - * Makefile: Use the more common .hex extension for Intel hex files instead of - more precise .ihx extension. This change has ripple effects to many build- - related scripts and programs and could cause some short-term problems. - * configs/stm3240g-eval/, arch/arm/src/stm32/up_allocateheap.c: Add support - for the 16-mbit SRAM on-board the STM3240G-EVAL board. - * drivers/usbdev/cdcacm.c and include/nuttx/usbdev/cdcacm.h: The CDC/ACM - driver can now be dynamically connected and disconnected from the host - under software control. - * include/nuttx/arch.h, configs/stm3240g-eval/src/up_cxxinitialize.c, and - configs/stm3240g-eval/src/up_cxxinitialize.c: Add support for C++ static - initializers. - * net/setsockopt.c, net/getsockopt.c, net/bind.c, net/socket.c: Add more - low level, thread-independent socket interfaces for use within the OS. - Some of these are currently used by the FTP controlling terminal. More will - be used to support the NFS file system currenly underwork. - * include/nuttx/net/: Major re-organization of networking headerf files. - Moved all non-standard, NuttX-specific header files from include/net and - include/nuttx into include/nuttx/net. - * arch/mips/src/pic32mx/pic32mx_usbdev.c: The PIC32 USB driver now appears to - be fully functional. - * configs/sure-pic32mx/usbnsh and configs/sure-pic32mx/src: Add support for - NSH using only USB serial I/O to support the console. This is useful on - devices that have USB, but no serial port. - * arch/mips/src/pic32mx/pic32mx_spi.c: Add a PIC32 SPI driver. Initial - checkin is primitive, incomplete (lacks interrupt logic), and untested. - * configs/pic32-startkit/nsh: Completed verification of the PIC32 Ethernet - Starter Kit port. Added and verified the NuttShell (NSH) on the PIC32 - Ethernet Starter Kit. I can now (finally) claim to have complete the - basic port to this board. - * configs/pic32-startkit/nsh/up_usbdev, up_nsh.c, and up_usbterm.c: Verified - the USB (device) driver on the PIC32 Ethernet Starter Kit. - * arch/mips/src/pic32mx/pic32mx_ethernet.c: Verified the PIC32 Ethernet - driver on the PIC32 Starter Kit. Status: It is occasionally functional - but not stable enough for use. - * arch/arm/include/stm32, arch/arm/src/stm32: Add general support for - the STM32 F2 family.

To my knowledge this deadlock only occurs when running the - NSH command ifconfig over Telnet. In that case the function netdev_foreach - takes the network device semaphore, but so does the telnet logic causing - the deadlock. - * arch/arm/src/stm32/stm32_pm*.c: Add basic STM32 power management logic - that will eventually be used to implement low power states. - * arch/arm/src/stm32/stm32f*0xx_rcc.c: In order to use CAN2, both CAN1 and - CAN2 clocking must be enabled. - * arch/mips/src/pic32mx/picm32mx-usbdev.c: Several stall-related fixes so that - the USB device driver can used the mass storage class (which does a LOT - of stalling as part of its normal protocol). The PIC32 USB Mass Storage - device is, however, still non-functional when debug is OFF. - * include/nuttx/fs: Move all file-system related files from include/nuttx to - include/nuttx/fs. - * include/nuttx/serial: Move all serial-driver related files from include/nuttx to - include/nuttx/serial. - * include/nuttx/clock.h and sched/clock_initialize.c: Add a new OS interface - called clock_sychronize() that can be used to re-synchronize the NuttX - system time with a hardware RTC. This function is called normally at power - up but may also need to be called when recovering from certain low-power - usage states where the system time is no longer accurate. - * arch/arm/src/calypso and arch/arm/include/calypso: Support for the TI "Calypso" - phone processor. Contributed by Denis Carilki and includes the work of Denis, - Alan Carvalho de Assis, and Stefan Richter. - * configs/compal_e88 and configs/compal_e99: Support for Compal e88 and e99 phones - Contributed by Denis Carilki and includes the work of Denis, Alan Carvalho de - Assis, and Stefan Richter. - * arch/arm/src/lpc17xx: Several fixes for error that have crept in for the LPC17xx - DAC. Contributed by by Lzyy. - * graphics/nxconsole: Add a character driver that can be used as a console output - device for text output (still under development on initial check-in). - * graphics/nxmu: Fix several compilation errors that have crept into the multi- - user NX server because of lack of use. - * graphics/nxconsole: The NX text console is basically function (in multi- - user NX mode only). - * arch/arm/src/stm32/stm32_i2c.c: Correct a bug in the STM32 I2C driver. The - behavior of I2C status bits seems to be different between F1 and F4. - * configs/stm3210e-eval/nxconsole: New STM32 F1 configuration that runs the - NuttShell (NSH) within an NX window. - * graphics/nxconsole/nxcon_sem.c: Add protection from re-entrance with debug - is enabled. - * include/nuttx/ascii.h and vt100.h: Header files to centralize ASCII and - VT100 escape sequence definitions. - * graphics/nxconsole/nxcon_vt100.c: Add add framework to support VT100 escape - sequences in NxConsole. - * fs/fs_read.c: Fix read() return value for attempt to read from write-only - file or device. Was returning EBADF, should return EACCES. - * graphics/nxconsole.c: NxConsole now supports backspace and a cursor. - * Kconfig and arch/sim/Kconfig: Beginnings of support for a NuttX - configuration tool. Currently using the kconfig parser 'kconfig-frontend' - available at http://ymorin.is-a-geek.org/projects/kconfig-frontends - (version 3.3.0-1 is also available in the NuttX SVN at - trunk/misc/tools/kconfig-frontends-3.3.0-1.tar.gz). Contributed by Lzyy. - * */Kconfig: Added skeleton Kconfig files to all directories that - may need them. - * include/nuttx/math.h: Moved include/math.h to include/nuttx/math.h - because it conflicts too often with the system math.h (and people aren't - inclined to read the documentation on how to handle this). Now, if - CONFIG_ARCH_MATH_H=y is defined, the top-level makefile will copy - the redirecting math.h header file from include/nuttx/math.h to - include/math.h. So for the architectures that define CONFIG_ARCH_MATH_H=y, - include/math.h will be in place as it was before; for the architectures - that don't select CONFIG_ARCH_MATH_H, the redirecting math.h header - file will stay out-of-the-way in include/nuttx/. - * Kconfig, sched/Kconfig, lib/Kconfig, libxx/Kconfig, arch/sim/Kconfig, - drivers/Kconfig, drivers/mtd/Kconfig, drivers/input/Kconfig - drivers/analog/Kconfig, drivers/lcd/Kconfig: Updated kernel - configuration support provided by Lzyy. - * Kconfig: Many more Kconfig updates (no longer tracking in the ChangeLog) - * arch/arm/src/Makefile, arch/x86/src/Makefile, arch/avr/src/Makefile, - arch/mips/src/Makefile, arch/sim/src/Makefile, arch/hc/src/Makefile, - arch/sh/src/Makefile: The libgcc.a in newer versions of GCC now - have an dependency on an external implementation of abort(). This - required modification to the Makefiles that do the final link: Now - libgcc.a must be included within the group of libraries that are - search recursively. - * arch/arm/srm/stm32/stm32_otgfsdev.c: A USB OTG FS device-side driver - for the STM32 F4 (and maybe F2 and F1 connectivity line). - * tools/cmpconfig.c: A tool for comparing two configuration files. - * include/nuttx/usb/usbdev.h, drivers/usbdev/*, arch/*/src/*/*usb*.c: - Extend the USB device side interface so that EP0 OUT data can be passed - with OUT SETUP requests. - * include/nuttx/watchdog.h: Add the definition of a standard watchdog - driver interface. - * drivers/watchdog.c: The "upper half" watchdog timer driver. - -6.18 2012-05-19 Gregory Nutt - - * Kconfig: Continued Kconfig file updates (no longer tracking on a per-file - basis in the ChangeLog) - * arch/arm/src/stm32/stm32_iwdog.c and stm32_wwdog.c: Add the STM32 IWDG - and WWDIG watchdog timer driver. - * configs/stm3240g-eval/src/up_lcd.c: Add LCD from for the STM3240G-EVAL (the - initial check-in is just a stm3210e-eval driver with renaming). - * sched/sched_setscheduler.c: Correct successful return value (Contributed - by Richard Cochran). - * include/fcntl.h and lib/stdio: Ignore CONFIG_STDIO_LINEBUFFER is the - file was opened in binary mode. - * lib/stdio/lib_fopen.c: Correct an error in parsing open mode string. The - plus sign may not appear right after the basic mode. For example, "r+", "rb+", - and "r+b" are all valid open strings and mean the same thing. - * lib/stdio/lib_fopen.c: Correct return errno value from f_open() and - f_fdopen() if the open mode string is invalid. - * drivers/serial/serial.c: Do not disable Rx interrupts on each byte. - Rather, only disable Rx interrupts when the Rx ring buffer may be empty. - * include/nuttx/usb/audio.h: USB Audio 1.0 definitions (in progress). - * arch/arm/src/stm32/stm32fxx_dma.c: STM32 F4 DMA now supports circular - buffer mode (contributed by Mike Smith) - * arch/arm/src/stm32/stm32_serial.c: The serial driver can now support - Rx DMA into a circular buffer (contributed by Mike Smith) - * configs/pic32mx7mmb: Beginning of a configuration for the Mikroelektronka - PIC32MX7 Multimedia Board (MMB). - * net/recvfrom.c: Fix a compilation problem. Some UDP logic was conditioned - on TCP, not UDP. - * drivers/usbdev/cdcacm.c: Fix an infinite loop that occurs when the serial - device is unregisters. - * arch/arm/src/stm32/stm32_otgfs.c: The driver needs to reset the software (in - order to flush the requests) and to disable the software connection when the - device is unregistered. - * include/sys/prctl.h, sched/prctl.c, include/pthread.h: Add interfaces to - support getting and setting of the thread or task name. - * configs/ubw32: Added a configuration to support the Sparkfun UBW32 PIC32 board. - * configs/ubw32/nsh: Added an NSH configuration for the Sparkfun UBW32 PIC32 board. - * configs/ubw32/up_buttons.c: Added button support for Bit Whacker board. - * configs/stm3240g-eval/nxconsole: Added a configuration to run the NSH - shell in an NX window for the STM3240G-EVAL board. - * include/cxx/cunistd: C++ header file to make sure that everything in - unistd.h is in the std:: namespace. - * configs/sim/nxwm: Added a configuration for testing the NuttX Window Manager - (NxWM) - * fs/fs_fcntl.h: On success, always returned OK. However, some fcntl commands - require returning other values on success. - * Various files. Fix warnings about variables that were initialized by not used. - * configs/sim/*/defconfig: Changes to build a 32-bit simulation on a 32-bit - platform did not make into all of the Make.defs files. - * graphics/nxmu/nx_move.c: Wrong opcode was being used in the server message; - Also there was an error in the offset calculation. - * graphics/nxglib/fb/nxglib_moverectangle.c: Offset argument is really a - position, not an offset. - * graphics/nxtk/nxtk_drawframe.c: Framed windows are now drawn in three - colors (instead of just two). - * drivers/input/stmpe811_*: Added a driver to support the STMicro STMPE811 - IO Expander and touchscreen driver. - * configs/stm3240g-eval/nxwm: Added to configuration for testing the NxWM - window manager on the STM3240G-EVAL board. - * graphics/nxtk/nxtk_toolbarbounds.c: Added an interface to get the toolbar - bounding box. - * graphics/nxtk/nxtk_drawframe.c: Fix an error in drawing the window frame. - * NX, NxConsole: Replace CONFIG_NXCONSOLE_NOGETRUN to CONFIG_LCD_GETRUN. The - inability to read from the LCD is a property of the LCD, not of NxConsole. - Then add CONFIG_NX_WRITEONLY which is the more generic way of saying that - no NX component should try to read from the underlying graphic device (LCD - or other). - * configs/stm3240g-eval/src/up_stmpe811.c: Add board-specific support for the - the STMPE811 I/O expander on the STM3240G-EVAL board. Verfied that the - STM3240G-EVAL touchscreen is now fully functional. - * include/cxx/cfcntl: Added std:: header file. - * graphics/nxbe/nxbe_filltrapezoid.c and graphics/nxglib/fb/nxglib_filltrapezoid.c: - Fix several errors in the trapezoid fill logic. - * include/nuttx/input/touchscreen.h, configs/hymini-stm32, configs/stm3240g-evel, - * configs/sam3u-ek, configs/sim, arch/sim/src/up_touchscreen.c, and - apps/examples/touchscreen: Standardize the board-specific, touchscreen - initialization interfaces. - * drivers/input/stmpe811_base.c and configs/stm3240g-eval: The STMPE811-based - touchscreen seems to work better with edge (vs. level) interrupts - * drivers/input/stmpe811_tsc.c: Fix some status checks so that the touchscreen - interrupt handling logic does not read data if the fifo is not at the - threshold level. - * include/nuttx/wqueue.h: Add macro work_available() to determine if the - previously scheduled work has completed. - * drivers/stmpe811_tsc.c: Correct errors: (1) Since all interrupt logic is done on - the worker thread, disabling interrupts does not provide protected; Need to - disable pre-emption. (2) Fix handling of touch ID and (2) add some logic to - prevent certain kinds of data overrun. - * include/nx/nxtk.h and graphics/nx/nxtk/nxtk.h: Move setting - of configuration defaults from the internal header file to a place where - other logic can use the defaults. - * graphics/nxtk/nxtk_events.c: Fixed an important but in the logic that - translates the mouse/touchscreen position data for framed windows and toolbars. - * drivers/input/stmpe811_tsc.c, tsc2007.c, and ads7843e.c: Need to keep track of - when if positional data is valid. When the touch is released, the X/Y position - of the release must be the same as the X/Y position of the last touch (se that - the release occurs in the same window as the last touch). - * graphics/nxtk/nxtk_events.c: Fix an error in mouse/touchscreen input logic: - Was autoraising the window AFTER processing the mouse press. This raises havoc - if the result of processing the mouse click was to raise some other window! - * graphics/nxtk/nxtk_events.c: I had to disable the whole autoraise feature - for multi-user case because it does not work correctly. In a scenario where (1) there - are multiple queued touchscreen events for the same window and (2) the result of the - first input was to switch windows, then the autoraise implementation will cause the - window to revert to the previous window. Not good behavior. - * sched/sched_mergepending.c: Add task switching instrumentation. There is a case - here where instrumentation was missing. Contributed by Petri Tanskanen. - * CONFIG_STMPE811_THRESHX, CONFIG_STMPE811_THRESHX, and drivers/stmpe811_tsc.c: Add some - thresholding controls to all slow down processing of touchscreen samples. - This is a problem with NX in multi-user mode: touchscreen data gets sent - via a message and when the message queue gets full the sender blocks and - touch events are lost. Basic data overrun. The badly effects touchscreen - human factors. - * include/sched.h: Fix a typo (missing semicolon) in prototype of on_exit(); - * sched/on_exit.c and include/nuttx/sched.h: Fix some old typos that caused - compilation errors when CONFIG_SCHED_ONEXIT is defined. - * configs/stm3240g-eval/nxwm/defconfig: The default NxWM now uses the STMPE811 - touchscreen. - * include/cxx/csched: Added - * graphic/nxmu/nxmu_sendserver.c, nxmu_sendwindow.c, and nxmu_sendclient.c: - Refactor NX messaging logic in preparation for a new message control - feature. - * graphics/nxtk, graphics/nxmu, include/nuttx/nx: Add a new window communication - to support blocking and flushing of client window messages. If there are - stale, queue window messages at the time that a window is destroyed, very bad - things happen. - -6.19 2012-06-15 Gregory Nutt - - * graphics/nxconsole/nxcon_kbdin.c: If selected, the NxConsole will take - input from the NX keyboard input callback. If this option is set, then - the interface nxcon_kdbin() is enabled. That interface may be driven by - window callback functions so that keyboard input *only* goes to the top - window. If CONFIG_NXCONSOLE_NXKBDIN is not selected, then the NxConsole - will receive its input from stdin (/dev/console). This works great but - cannot be shared between different windows. Chaos will ensue if you - try to support multiple NxConsole windows without CONFIG_NXCONSOLE_NXKBDIN - * graphics/nxmu/nx_kbdin.c: Fix pointer argument. This is a error - introduced in changes leading up to the 6.18 release. This error will - cause crashes or perhaps simply not work when you try to handle window - keyboard data in multi-user mode. - * graphics/nxconsole/nxcon_kdbind.c: Fixed unmatched sem_wait and sem_post. - Fix some conditional compilation that included a few too many lines of code. - * drivers/input/stmpe811_tsc.c and stmpe811.h: Add a timeout to catch missed - pen up events. Now the STM3240G-EVAL touchscreen works very smoothly. - * configs/stm3240g-eval/nxwm/defconfig: Enable support for NxConsole keyboard - input. Increasing spacing of icons. - * configs/stm3240g-eval/nxwm/defconfig: Use a larger font for the calculator. - * include/nuttx/lcd/ssd1289.h, drivers/lcd/ssd1289.c and .h: Generic LCD - driver for LCDs based on the Solomon Systech SSD1289 LCD driver. This - of this as a template for an LCD driver that will have to be cusomized - for your particular LCD hardware. - * configs/stm32f4discovery/src/up_extmem.c and up_ssd1289.c: Add support to - STM32F4Discovery for than an external, SSD1289-based LCD. - * configs/stm32f4discovery/nxlines: Add an STM32F4Discovery configuration - to thest the SSD1289-based LCD. - * configs/stm3240g-eval/src: Add USB GPIO initialization logic needed - in board-specific boot logic. - * configs/stm32f4discovery/src: Add USB GPIO initialization logic needed - in board-specific boot logic. - * drivers/usbdev/pl2303.c and cdcacm.c: Fix the request size used for sending - packets. It was not using the maximum request size, but instead the previous - request size. As a result, packets get smaller, and smaller, and ... This - is an important USB serial fix. - * arch/arc/src/stm32_otgfsdev.c: Bug fix: Don't process TXFE if we have - already processed an XFRC interrupt. We have already done what needs - to done in that case. - * arch/arc/src/stm32_otgfsdev.c: Fixed some status settings in queuing of write - messages. Added a "hack" to work around missing TxFIFO empty interrupts. The - hack is basically to poll for space in the TxFIFO instead of of setting up - the interrupt. - * arch/arm/src/stm32/stm32f2* and chip/stm32f2*: Update all STM32 F2 file so - that they are equivalent to F4 files. This is kind of a maintenance nightmare. - * configs/stm3220g-eval/: Update existing configurations to the same level - as the corresponding STM3240G-EVAL configurations. This adds FSMC SRAM, - touchscreen, and LCD support. - * configs/stm3220g-eval/: Add a NxWM configuration for the STM3220G-EVAL. - * stmpe11*: Fix a massive naming problem. All references to STMPE11 should be - STMPE812. - * arch/arm/src/stm32/stm32_otgfsdev.c: Need to enabled USB reset interrupt - (contributed by Erik Van Der Zalm). - * sched/sleep.c: Fix the return value from sleep(). The correct behavior is - to return the number of unwaited seconds; the implementation was always - returning zero. - * sched/usleep.c and include/unistd.h: Was a void function, but should return - 0 on success. usleep() needs to check the return value from sigtimedwait(). - sigtimewait() returns the signal number that awakened it and an error (EAGAIN) - if the timeout expired (normal case). - * sched/sig_timedwait.c: Fix sigtimedwait() return value. On a timeout, it was - setting the 8-bit si_signo field to -1 and eded up reported successfully awakened - by signal 255! Now detects the timeout and errors -1 with errno == EGAIN. If - sigtimedwait() is awakened by an unblocked signal, but it is not one of the - signals in the waited-for set, it will return -1 with errno == EINTR. - * arch/arm/src/stm32_i2c.c: Fix STM32 F2 I2C. It is apparently bug-for-bug - compatible with the F4 and needs the same work-around for the missing BTF - signal that was needed for the F4. - * drivers/lcd/ssd1289.*: Fix some of the initial register settings. - * configs/stm32f4discovery/src/up_ssd1289.c: FSMC address bit 16 is used to - distinguish command and data. But FSMC address bits 0-24 correspond to ARM - address bits 1-25, se we need to set bit 17 in order generate output on - FSMC_A16. - * arch/arm/src/lm3s/lm3s_epi.h and lm3s_timer.h: LM3S header files - (contributed by Max Neklyudov). - * arch/arm/src/stm32/stm32_irq.c: Some of the interrupt priorities were - not be initialized (F2 and F4 only). Thus, the very high numbered - interrupts (like UART6) and cause nested interrupts. This leads to - some very difficult to debug crashes. Fix contributed by Mike Smith. - * arch/mips/src/pic32/pic32_head.S and pic32_config.h and - configs/pic32mx7mmb/include/board.h: Extended PIC32 device configuration - capabilities and change board.h to support unique clocking requirements - of the Mikroelektronika PIC32MX7 MMB. That board now works! - * configs/pic32mx7mmb/nsh: Added and verify a NuttShell configuration - for the Mikroelektronika PIC32MX7 MMB board. - * arch/mips/pic32/pic32mx-ethernet.c: Fix logic that guesses PHY address; - the search loop missed the PHY address needed by the Mikroelektronika - PIC32MX7 MMB board. - * configs/pic32mx7mmb/nsh: Configuration now supports a network by default. - * configs/pic32mx7mmb/src: Add support for the MMC/SD slot on board - the Mikroelektronika PIC32MX7 MMB board (not working on initial check-in). - * arch/mips/src/pic32/pic32mx-spi.c: Add support for very low-level, - register access debug output. - * configs//pic32mx7mmb/include/board.h: Reduced peripheral clock to - 4MHz to match other PIC32 configurations. - * configs/pic32mx7mmb/src/up_nsh.c: SD card needs to operate in SPI - mode 2. - * configs/pic32mx7mmb/nsh/defconfig: MMC/SD card support is now - enabled by default in the PIC32MX7 MMB board configuration. - * configs/pic32mx7mmb/nsh/defconfig: Verified the USB Mass Storage - Class (MSC) using MMC/SD card as the logical unit. Updated the default - PIC32MX7 MMB board configuration so that USB and the mass storage class - are enabled by default. - * drivers/lcd/mio283qt2.c and include/nuttx/lcd/mio283qt2.h: Add generic - support for the MIO283QT2 LCD. - * configs/pic32mx7mmb/src/up_mio283qt2.c: Add support for the MIO283QT2 - LCD on the PIC32MX7 MMB board. - * configs/pic32mx7mmb/src/up_touchscreen.c: Add an ADC-based touchscreen - driver for the PIC32MX7 MMB board. Kind of works, but needs more - verification and tuning. - * arch/mips/src/common/up_idle.c: Strange but important fix. For some still- - unknown reason, interrupts are left in an unhealthy state in the IDLE - when the work queue is enabled. This is partially because some interrupt - related logic is not built in that case. Simply disabling then re- - enabling interrupts restores the proper state. - * graphics/nxglib/lcd/nxglib_filltrapezoid.c and fb/nxglib_filltrapezoid.c: - Fix an error when the trapezoid is only 1 line high. In this case, a - divide by zero error would occur. The fix is to draw the 1 line high - trapezoid as a run. - * drivers/usbdev/pl2303.c: Fix a cut'n'paste error that snuck into - the PL2303 emulation driver several months back. - -6.20 2012-07-12 Gregory Nutt - - * configs/stm3210e-eval/src and arch/arm/src/stm32/: Add beginnings of - power management support for the STM32 and the STM3210E-EVAL board, in - particular. - * Documentation/NfsHowTo.html: Add a How-To document for the new NFS - client feature. - * arch/mips/include/pic32mx and arch/mips/src/pic32mx: Add support for the - PIC32MX1 and PIC32MX2 families. - * configs/mirtoo: Add a board configuration to support the DTX1-4000L - "Mirtoo" module from http://www.dimitech.com/ - * tools/pic32mx: All of the duplicate directories containing the same - same PIC32 tools were move to this single location. - * configs/mirtoo: The basic Mirtoo port is now functional. - * configs/mirtoo/ostest: Added support for the microchipOpen toolchain - (see http://sourceforge.net/projects/microchipopen/). - * configs/mirtoo/nsh: Added a NuttShell (NSH) configuration for - the Mirtoo module. - * configs/mirtoo/scripts: Move all Mirtoo linker scripts to a common - directory. - * arch/mips/src/pic32mx/pic32mx-gpio.c: All digital inputs were being - configured as outputs. This is a *critical* bug fix and needs to be - incorporated by any PIC32 users. - * drivers/mtd/sst25.c: Added a driver for the SST 25 SPI-based FLASH - parts. - * configs/mirtoo/src/up_nsh.c: The Mirtoo NSH configuration can now - mount the SST 25 devices so that it can be used for a FAT file system. - There are are, however, some NSH memory usage issues if this configuration - enabled now. Some tuning is still needed. - * configs/mirtoo/nxffs: Add an alternative NSH configure for the Mirtoo - module for testing the on-module SST 25 chip using the NXFFS file system. - * arch/arm/src/lpc43xx and arch/arm/include/lpc43xx: The NXP LPC43xx port - is slowly evolving in these directories. - * configs/stm3210e-eval/pm: Add a new configuration for testing STM32 power - management. - * configs/stm3210e-eval/scripts: Moved all of the duplicate ST3210-EVAL - linker scripts into one set of linker scripts at this location. - * configs/stm3210e-eval/src/up_buttons.c, up_lcd.c, and up_pm.c: New logic - for testing STM32 power management. - * configs/lincoln60: Add a configuration to support the Micromint Lincoln60 - board. - * configs/ekk-lm3s3b96: Add a configuration to support the TI/Stellaris - EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V. - * arch/arm/src/lpc43xx/chip: Created header files for *all* (really) - lpc43xx registers and all bit-fields. - * configs/lpc4330-xplorer: Added a configuration for the NXP LPC43XX - Xplorer board. This is just to facilitate testing of the LPC43xx - port but will, with any luck, become proper board support for that - board. - * arch/arm/src/lm3s/lm3s_syscontrol.c: Fix an optimization related problem - by adding a volatile qualifier to a timing loop. Oddly, the consequence - of the bug is that when debug was off, the LM3S platform too a long time - to boot. It now boots rapidly whether debug is on or off. - * arch/*/include/limits.h: Change all values in all limits.h for all - architectures to signed decimal; the hex values were not sign extending - appropriate in most uses (reported by Lorenz Meier). - * arch/arm/src/stm32/chip/stm32f103/7vc_pinmap: Fix typographical error in - two pinmap definition files. - * lib/net/lib_inetntoa.c: Fix typographical error that cause compilation - failure on platforms that do not support passing of structures as - parameters. - * arch/arm/*/lpc43xx and configs/lpc4330-xplorer and code complete and - ready for testing. Hopefully, verified LPC43xx support will appear - in NuttX-6.20. - * include/nuttx/stdarg.h: If CONFIG_ARCH_STDARG_H=y is defined, the top-level - makefile will copy the generic (GCC-only) stdarg.h header file from - include/nuttx/stdarg.h to include/stdarg.h. So for the architectures - that cannot use their GCC toolchain's stdarg.h file, they can use this - alternative by defining CONFIG_ARCH_STDARG_H=y. If CONFIG_ARCH_STDARG_H, - is not defined, then the redirecting stdarg.h header file will stay - out-of-the-way in include/nuttx/. - * configs/lpc4330-xplorer/nsh: Add an NSH configuration for the LPC4330 - Xplorer board. - -6.21 2012-08-25 Gregory Nutt - - * configs/lpc4330-xplorer/up_nsh.c: Add support for a basic SPIFI block - driver for use by NSH. Does not work! Crashes on first SPIFI write. - * configs/lpc4330-xplorer/*/defconfig: Calibrate delay loops (this is - based on the current "slow" 72MHz M4 clock and will need to be - re-calibrated when this is increased). - * configs/stm3220g-eval/include/board.h and configs/stm3240g-eval/include/board.h: - The SDIOCLK frequency in the F2 and F4 derives for PLL48CLK and not HCLK - so that the SDIOCLK input frequency should always be 48MHz. - * sched/os_internal.h, sched_setupidlefiles.c, sched_setuptaskfiles.c, and - sched_setupidlefiles.c: Detangle some conditional compilation. Allow for - a perverse configuration that has socket descriptors and streams but no file - descriptors (sure, why not?). - * sched/: Stylistic clean-up of all files. Some of these files are pretty old - and do not follow current NuttX coding standards in detail. - * fs/: More stylistic file clean-up. - * mm/: More stylistic file clean-up. - * drivers/ and drivers/serial/: More stylistic file clean-up. - * arch/arm/src/lpc43xx/lpc43_clockconfig.c: Fix PLL1 bit manipulation logic. - Critical bugfix! This would often cause the LPC43xx to fail to boot. - * arch/arm/src/lpc43xx/lpc43_rgu.c: The soft reset logic called from the - beginning of __start seems cause problems. A magic delay seems to improve - the logic some. But I suspect that real fix is to get rid of all of the - soft reset logic. This would also be a critical bugfix if I believed - that it really fixed all of the issues. - * arch/arm/src/lpc43xx/chip/lpc43_cgu.h: Fix a bit mask in the PLL1 - control register. Critical bugfix. - * arch/arm/src/lpc43xx/lpc43_clockconfig.c and configs/lpc4330-xplorer/include/board.h: - Implement PLL1 ramp-up logic; Now the LPC43xx is running at 204MHz. - * configs/lpc4330-xplorer/*/defconfig: Re-calibrated delay loops using - the 204MHz clock. The LPC43xx ripping rips! This calibration was performed - with symbols enabled and all optimization disabled. It will need to be - better recalibrated again down the road. - * arch/arm/src/stm32/stm32_exti.c: Renamed to rch/arm/src/stm32/stm32_exti_gpio.c - to make a little room in the file name space. - * arch/arm/src/stm32/stm32_exti_alarm.c: Add initial logic to attached the - RTC alarm EXTI interrupt. This is work be performed mostly by Diego Sanchez. - * include/: More stylistic file clean-up. - * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: Add - logic to configure and initialize the SPIFI device (does not yet work). - * configs/lpc4330-xplorer/include/board.h: Reduce SPI SCLK value. - * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: - Logic completely redesigned. It now creates an MTD driver to access SPIFI... - but the driver still does not work. - * arch/arm/src/stm32 and arch/arm/include/stm32: Make name of RTC ALARM interrupt - common on STM32 F1,2,4 - * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the - STM32F100x "Value Line" devices. This includes changes to stm32F10xx_rcc.c that - add the ability to run the chip off the internal oscillator. There is no open - board configuration for this part yet (the STM32VLDiscovery would be a candidate). - Contributed by Mike Smith. - * arch/arm/src/stm32: Fixed typos in conditional compilation in the CAN and DMA - and some pin configuration. This would have caused problems for STM32 F107xx. - Typos noted by Mike Smith. - * arch/arm/src/lpc43xx/lpc43_serial.c: Add support for certain RS-485 features - * lib/termios/lib_cfsetispeed.c, lib_cfsetospeed.c, lib_tcflush.c: Add - simple implementations of cfsetispeed(), cfsetospeed(), and tcflush(). - * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: - Add APIs to support setting non-standard BAUD values not supported by POSIX - termios. These are non-standard interfaces but have a precedence: There are - similar interfaces in AIX. - * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: - Sigh... removed. We don't need any more almost standard interfaces! (SVN - revision 4968 if you want the short-lived code). - * include/termios.h and lib/termios/*: Open the existing, standard termios - interfaces to permit some non-standard baud settings. The new termios definitions - still supports the POSIX standard except that it does not strictly enforce - baud rate settings, permitting some non-portable, but useful baud rate settings - (this is what the short-lived AIX-like interfaces would have accomplished as well). - * include/termios.h and lib/termios/*: Redesigned yet again (this is getting - painful. NuttX now supports the BOTHER baud setting just as Linux does. termios - Bxxx definitions are again encoded; cf[set|get][o|i]speed now deal with only the - encoded values. If the encoded baud is set to BOTHER, then the values in the (non- - standard) c_ispeed and c_ospeed baud values may be accessed directly. - * arch/arm/src/stm32/stm32_serial.c: Add minimal termios support for the STM32 - (BOTHER style baud settings only). Contributed by Mike Smith. - * configs/lpc4343-xplorer/src: Clean up SPIFI-library based build to that it - actually works. - * arch/arm/src/lpc43xx/lpc43_spifi.c: Add support for verification to writes. - Add debug option to dump buffers. Several bugfixes... almost works. - * include/termios.h, lib/termios/*, and arch/arm/src/stm32/stm32_serial.c: : - BOTHER is gone again. - * arch/arm/src/stm32/stm32_sdio.c and chip/stm32f20xx_pinmap.h: STM32 F2 SDIO - fixes from Gary Teravskis and Scott Rondestvedt. - * include/termios.h and lib/termios/*: Replace cfsetispeed and cfsetospeed with - cfsetspeed (with definitions for the input/outputs in termios.h). - * configs/stm32f4discovery/src and configs/stm32f4discovery/pm: Add a power - management configuration for the STM32F4Discovery and supporting logic. This - check-in also includes some fixes for the F4 RTC alarm logic. - * drivers/input/pga11x.c and include/nuttx/input/pga11x.h: Add support for the - TI PGA112/3/6/7 amplifier/multiplexer parts. - * configs/mirtoo/README.txt, nsh/defconfig, and nxffs/defconfig: Add support - for the PGA117 on the Mirtoo module. - * drivers/analog/pga11x.c and include/nuttx/analog/pga11x.h: These belong in - the analog subdirectories, not input. - * configs/compal_e99/src/ssd1783.c and /ssd1783.h: Drivers for the SSD1783 - LCD found in the Motorola C155 telephone. The driver is specific to the C155 - because it uses the uwire transport. Contributed by Denis Carilki and - Alan Carvalho de Assis. - * drivers/power/pm_changestate.c. Correct a case where interrupts were not - being re-enabled. Found by Diego Sanchez. - * configs/mirtoo/nxffs/defconfig: This Mirtoo NXFFS configuration now uses the - open Pinguino toolchain by default. This is necessary because the free C32 - toolchain does not support any optimization and the unoptimized NXFFS image - hits the PIC32MX2 FLASH size (128K). There is plenty of room to grow using - the Pinguino toolchain with -O2 optimization. - * configs/mirtoo/src/up_adc.c. This is just a stub for now, but this is - where Mirtoo ADC logic will eventually need to go. - * arch/mips/src/pic32mx/pic32mx-gpio.c: Now supports the PIC32MX1/2 ANSEL - IOPORT register. - * lib/string/lib_memchr.c: Add support for memchr() (contributed by Mike Smith) - * lib/string/lib_memccpy.c: Add support for memccpy() - * arch/arm/src/lpc17xx/lpc17_serial.c: Now supports ioctl commands to change - the baud using tcsetattr() (contributed by Chris Taglia). - * arch/*/src/*_serial.c: Fix ioctl method return values. These methods - should return a negated errno value; they should not set the errno - variable. - * sched/on_exit.c, sched/task_exithook.c, and include/nuttx/sched.c: Add - support for multiple registered on_exit() functions if CONFIG_SCHED_ONEXIT_MAX - is defined. - * drivers/syslog/ramlog.c: Move the RAM SYSLOG device into drivers/syslog - so that it will be in the same directory as some new SYSLOGing devices - in the works. - * include/nuttx/syslog.h and drivers/syslog/ramlog.c: The SYSLOG putc function - now has a common name that is independent of the device that provides the - SYSLOG. - * include/nuttx/syslog.h and drivers/syslog/syslog.c: This is a new, generic - SYSLOG device that can redirect debug output to any character device or file. - So you can log debug output to a file or you can put the console on /dev/ttyS0 - and the debug output on /dev/ttyS1. - * arch/arm/src/lpc43xxl/lpc43_spifi.c: Correct an addressing error in the LPC43 - SPIFI MTD driver - * drivers/syslog/syslog.c and fs/fs_syslog.c: Moved the generic syslog logic - from drivers/syslog to fs/ where is belongs. Especially after realizing that - the syslog logic is going to have to some internal FS operations in order - to realize a totally thread-independent SYSLOG interface. - * arch/arm/src/stm32/stm32*_rcc.c and .h: If CONFIG_PM is defined, add a - function called stm32_clockenable() that can be used by PM logic to re-start - the PLL after re-awakening from deep sleep modes. - * fs/fs_foreachinode.c and fs/fs_foreachmountpoint.c: Add logic to traverse - inodes and mountpoints in the NuttX pseudo-file system. - * fs/fat/fs_fat32.c: Max. filename length reported by statfs() was wrong - if FAT long file names were enabled. - * lib/stdio/lib_libvsprintf.c: Fieldwidth and justification were not - supported for the %s format. As a result, %s, %12s, and %-12s all - produced the same output. - * lib/stdio/lib_libdtoa.c: Fix several issues with presenting floating - point numbers (conversions are fine, but presentation was bad). This - is a critical bug fix if you use printf or sprintf to deal with floating - point numbers. - * lib/stdio/lib_libdtoa.c and lib_libvsprintf.c: Correct some floating - point options. - * arch/arm/lpc43xx/lpc43_usb0dev.c: Add framework for development of - an USB0, device-side driver for the LPC43XX. The initial check-in, - however, is simply for the LPC31xx driver with name changes. The - LPC31xx has the same USB IP, but will require some additional initialization - (and lots of testing) before it can be used with the LPC43xx. - * nuttx/Documentation/NuttShell.html: Added a section covering ways to - customize the behavior of NSH. - * arch/arm/src/stm32/chip/stm32f1*_pinmap.h: STM32 CAN TX/RX pins reversed; - inconsistent conditional compilation. Reported by Max Holtzberg. - * arch/arm/*/stm32: Add support for STM32 F107 "Connectivity Line" - Ethernet (contributed by Max Holtzberg). - * configs/olimex-stm32-p107: Add board support for the Olimiex STM32-P107 - board (contributed by Max Holtzberg). - * arch/arm/src/stm32/stm32f2xx_dma.c, stm32f4xx_dma.c, stm32_serial.c, and - stm32_spic.c: DMA priority was getting zeroed by STM32 F2/F4 DMA drivers - so that all DMAs ran at the lowest priority. - * configs/stm3240g-eval/include/board.h and configs/stm3220: Drop SD card - frequency from 24 to 16 MHz. Apparently 24 MHz is too fast for the board. - This (plus the change to the STM32 DMA (above) fixes SDIO DMA on the - STM3240G-EVAL (and probably STM3220G-EVAL -- untested). - * arch/arm/src/stm32/stm32f2xx_dma.c and stm32f4xx_dma.c: Backed out the - DMA priority change just above. The reduced SD card frequency was - necessary and sufficient to resolve the problem. - * drivers/serial/serial.c: open, read, write, and poll methods may now - abort return EINTR (or a short transfer size) if a signal is received - while waiting to receive or send serial data. This behavior is required - by POSIX. - * include/sys/types.h: Define NULL to be (0) if __cplusplus is defined. - (contributed by Mike Smith) - * include/ctype.h: Remove a stray semi-colon in a definitions (Thanks - Mike Smith). - * configs/.../Make.defs. Fix C++ include path set-up in Make.defs file - for all 8-bit AVR platforms (Thanks Richard Cochran). - * lib/stdio/lib_*stream.c: Revised to handle new error return values from - serial.c. - * arch/arm/src/stm32/stm32_spi.c: SPI driver can now service re- - initialization (Mike Smith). - * tools/mkconfig.c: If CONFIG_DRAM_END is not specified, this tool - will provide default definition of (CONFIG_DRAM_START + CONFIG_DRAM_SIZE) - * arch/arm/src/stm32/stm32_otgfshost.c: Renamed from stm32_usbhost.c. - This is nearly code complete and, with any luck, will be available - in NuttX-6.21. - * configs/*/defconfig: Update all defconfig files to remove syntax - that is incompatible with the mconf configuration tool. - * arch/arm/src/stm32/stm32_otgfshost.c: This driver now appears to be - functional (although more testing is necessary). - -6.22 2012-09-29 Gregory Nutt - - * include/semaphore.h, sched/sem_holders.c, and lib/semaphore/sem_init.c: - Fix some strange (and probably wrong) list handling when - CONFIG_PRIORITY_INHERITANCE and CONFIG_SEM_PREALLOCHOLDERS are defined. - This list handling was probably causing errors reported by Mike Smith - * sched/sched_waitpid.c: Fix a possible issue with logic logic that - should be brought into a critical section (suggested by Mike Smith) - * sched/sched_setuptaskfiles.c: Should be 'struct socket' not - 'struct sockets'. How did this compile before? (found by Kate) - * syscall/syscall.csv: Fix prototype for usleep() and prctl() (also - from Kate). - * arch/arm/src/lpc17xx/lpc17_ethernet.c: Conditionally elide setting PHY - speed/duplex. This does not work for certain PHYs. Still some unresolved - issues (also from Kate). - * tools/Config.mk, Makefile, configs/*/Make.defs: Add a new Makefile - fragment to de-quote certain strings from the Kconfig logic that - need to be used at path segments (Richard Cochran). - * arch/arm/src/stm32/stm32_usbotghost.c: The STM32 USB host driver only - works with debug turned on. The problem appears to be that with debug - OFF, there are more NAKs occuring in more places than before and this - reveals a variety of errors. This check in improves NAK robustness - for control transfers but does not resolve all of the issues. - * configs/stm3220g-eval/*/defconfig: Calibrated delay loop. It had - never been calibrated was way off. - * sched/sem_holder.c: Add logic to handler some priority inheritance - cases when sem_post() is called from an interrupt handler. The - logic is clearly wrong, but it is not known if this is the - cause of any known bugs. - * lib/stdio/lib_perror(): Add perror(). Contributed by Kate. - * lib/string/lib_strerror(): Add option CONFIG_LIBC_STRERROR that - is now required to enabled strerror(). Add an option - CONFIG_LIBC_STRERROR_SHORT that can be used to output shortened - strings by strerror(). - * arch/arm/src/stm32/stm32_usbotghost.c: Finally... the USB OTG FS - appears to handle NAKing correctly. - * configs/stm32f4discovery/*: Added and verifed support for USB OTG FS - host on the STM32F4Discovery board. - * configs/*/defconfig: Remove configuration documentation from config - files. It is redundant, error-prone, and difficult to maintain. - Configuration documentation is available in configs/README.txt for - common configurations and in configs/*/README.txt for board and MCU- - specific configurations. - * configs/stm3240g-eval: Add USB host support. - * sched/os_bring.c, configs/*/defconfig, tools/mkconfig.c, and others: Added - configuration variable CONFIG_USER_ENTRYPOINT that may be used to change - the default entry from user_start to some other symbol. Contributed by - Kate. NOTE: This change does introduce a minor backward incompatibility. - For example, if your application uses NSH as its start-up program, then your - build will now fail because it will be unable to find "user_start". The fix - for this link failure is to add the following to your configuration file: - CONFIG_USER_ENTRYPOINT="nsh_main". - * libs/stdio/lib_libfread.c and lib_*flush*.c: Correct a couple of - error cases where the lib semaphore was not be released on error - exits (thanks Ronen Vainish). Also, improved some error reporting: - the generic ERROR was being used instead of the specific errno - value; the errno variable was not always set correctly. - * tools/mkfsdata.pl: The uIP web server CGI image making perl script was - moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl - (Part of a larger change submitted by Max Holtzberg). - * configs/stm3240g-eval/script/ld.script: All of the identical ld.script - files for the STM3240G-EVAL were replaced by one version in this directory. - * configs/stm3240g-eval/webserver: Configuration submitted by Max Holtzberg - for testing the changes to the uIP web server (see apps/ChangeLog.txt). - * lib/stdio/lib_perror.c: Remove CONFIG_LIBC_PERROR_DEVNAME. What was I - thinking? Arbitrary streams cannot be shared by different tasks. - * tools/mksyscall.c, csvparser.c, and csvparser.h: Separate CSV parsing - logic from mksyscall.c into files where it can be shared. - * tools/mksymtab.c: Add a tool that can be used to convert a CSV file - into a NuttX-style symbol table. - * sched/work_cancel.c: Fix a bad assertion (reported by Mike Smith) - * configs/stm3210e-eval/src/up_idle.c: Correct some power management - compilation errors (reported by Diego Sanchez). - * include/nuttx/wqueue.h, sched/work*, and others: Added logic to support - a second, lower priority work queue (CONFIG_SCHED_LPWORK). - * arch/arm/src/stm32/stm32_dma.c, chip/stm32*_memorymap.h: FSMC SRAM is - only 16-bits wide and the SDIO DMA must be set up differently. - * arch/arm/src/stm32/stm32_dma.c: Back out the 16-bit DMA change. It - is incorrect. - * configs/: Make use of UART4/5 vs USART4/5 consistent in all places. - * Kconfig: Serial 2STOP setting must be integer 0/1, not a boolean. - * lib/misc/sendfile.c and include/sys/sendfile.h: Add a Linux style - sendfile() (non-standard!) - * Kconfig: Refactor serial settings (moved from chip to drivers/serial). - AVR "teensy" now builds with Kconfig (contributed by Richard Cochran). - * Kconfig: Add configuration settings for the LPC17xx - * Kconfig: Add configuration settings for the LM3S (from Richard Cochran). - * Kconfig: Verify configuration settings for the STM32. This includes - changes in the way that the external SRAM is configured: Define - CONFIG_HEAP2_SIZE (decimal) instead of CONFIG_HEAP2_END (hex). - * tools/configure.sh: Don't append the apps directory path setting - if the correct setting is already in defined in the defconfig file. - * fs/fat/fs_utils.c: Improperly constructed bool expression. This - would cause many unnecessary writes to FLASH (Thanks Ronen Vainish). - * Kconfig: Verify configuration settings for the LPC43xx. This includes - some corrections to configuration variable names and defconfig settings. - * Kconfig: Add and verify configuration settings for the LPC31xx. - * arch/arm/src/stm32/stm32_uart.h and stm32_serial.c: Add logic to - re-initialize the console UART as needed to enable DMA on the - console UART (contributed by Mike Smith). - * net/recvfrom.c, net/Kconfig, include/nuttx/net/uipopt.h: Remove delay - after receiving data. That has historical reasons to be there (it - was needed before read-ahead buffering was added), but kills performance. - (Noted by Max Holtzberg). - * configs/shenzhou: Add beginnings of a board configuration for the - Shenzhou STM32107 board (see www.armjishu.com). Very little is in - place as of this initial check-in. - * QEMU: Fixes from Richard Cochran to build QEMU with Kconfig files. - * arch/*/src/Makefile: Remove some old logic that was kicked off - when CONFIG_BOOT_RUNFROMFLASH=y. The old logic used to use - objcopy to move sections. Newer logic changes the load position - of sections in the linker script. As far as I can tell, there - is nothing in the source tree now that depends on the old way of - doing things (if I am wrong, they will need a change to the linker - script). - * configs/fire-stm32v2: Configuration for the M3 Wildfire board. I - don't know very much about this board other than is has an - STM32F103VET6 chip, LCD, touchscreen, and ENC28J60 network. Very - little is in place on the initial check-in. - * configs/shenzhou: Coding for the Shenzhou board port is complete, - but tested has been deferred until I get the right tools. - * arch/arc/include/stm32/chip.h and arch/arm/src/stm32/chip.h: - Add support for the STM32F103VET6. - * fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted - by Ronen Vainish). - * drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever - uninitialized then there would be a double release of memory - (Noted by Ronen Vainish). - * fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed - by Kate). - * arch/avr/src: Fixes from AVR32 build errors that have crept in - over the time; incorporated Kconfig for AVR3 (Richard Cochran). - * fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates - memory for sector I/O buffers used to exchange data with the - configured block driver. In some contexts, the block driver may - require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined, - then the FAT FS will use platform-provided DMA memory allocators - to allocate the block driver I/O buffers. - * CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent - in all places. - * drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and - olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number - as a parameter. Instead now passes a call table to manage - ENC28J60 GPIO interrupts. That is because GPIO interrupts are - handled in different ways by different MCUs and some do not - support IRQ numbers for GPIO interrupts. - * mm/mm_gran* and include/nuttx/gran.h: Add a simple granule- - based allocator. The intent of this allocator is to support - simple allocation of DMA I/O buffers. The initial check-in - is code complete but untested (not event built into the - mm/Makefile yet. - * configs/fire-stm32v2: The board port is basically functional. - Not all features have been verified. The ENC28J60 network - is not yet functional. - * configs/stm3240g-eval/discover: A configuration for testing - the UDP discovery utility. Contributed by Max Holtzberg. - * mm/README.txt: Add a new README file. - * include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c: - Add hooks to use common, external DMA buffer allocation - implementation. - * net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering - is enabled and (2) some data was obtained from read-ahead buffers. - Blocking is a bad idea in that case because there is no timeout! - (submitted by Max Holtzberg). - * configs/stm3240g-eval/xmlrpc: An example configuration for the - Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc. - See http://www.drdobbs.com/web-development/ - an-embeddable-lightweight-xml-rpc-server/184405364 for more info. - Contributed by Max Holtzberg. - * configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for - bugs that crept in during recent changes. (Submitted by Max - Holtzberg). - * arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave(). - It looks like sometimes the compile will re-order some instructions - inapproapriately. This end result is that interrupts will get - stuck off. - * drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI - FLASH family (W25x16, W25x32, and W25x64). The initial check-in - is basically just the SST25 driver with some name changes. - * arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c: - Back out the last change in irq.h. It is (most likely) fine the - way it was. The really interrupt related problem was in stm32_spi.c: - When SPI3 is not enabled, then the irqrestore() falls in the - else clause. - * include/nuttx/compiler.h and other files: Moved always_inline - and noinline __attributes__ here. Also replaced all occurrences - of explicit __atributes__ in other files with definitions from - this header file. - * drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is - code complete (but still untested). - * arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith. - Unified configuration logic; dynamic timeout calculations; - I2C reset logic to recover from locked devices on the bus. - * configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all - common make definitions from the various Make.defs files into - the common tools/Config.mk. Add support for a verbosity options: - Specify V=1 on the make command line in order to see the exact - commands used in the build (Contributed by Richard Cochran). - * drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is - now functional. - * configs/fire-stm32v2: Add support or the fire-stm32v3 board as - well (untested because I do not have a v3 board). - * lib/stdio/lib_sscanf.c: Add %n pseudo-format (from Kate). - * lib/stdio/lib_sscanf.c: There is an issue of handling input - when (1) no fieldwidth is provided and (2) there is no space - seperating the input values. No solutions is in place for this - case now (either space or a fieldwidth must be provided). But - at least some of the bad logic that attempted to handle this - case has been removed (noted by Kate). - * arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an - even multiple of 4, 8, or 16 bytes. - * arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues: - We cannot go into sleep mode while Ethernet is actively DMAing. - * configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support - SSD1289 LCD. Initial checkin is just a clone of the - STM32F4Discovery's FSMC-based LCD interface. The Shenzhou - will need a completely need bit-banging interface; this - initial check-in is only for the framework. - * configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is - code complete. - * configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not - have an SSD1289 controller. Its an ILI93xx. Ported the - STM3240G-EVAL ILI93xx driver to work on the Shenzhou board. - * configs/shenzhou/nxwm: Added an NxWM configuration for the - Shenzhou board. This is untested on initial check-in. It will - be used to verify the Shenzhou LCD driver (and eventually the - touchscreen driver). - * configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen - support for the Shenzhou board. The initial check-in is untested - and basically a clone of the touchscreen support for the SAM-3U. - * tools/cfgparser.c: There are some NxWidget configuration - settings that must be de-quoted. - * arch/arm/src/stm32/Kconfig: There is no SPI4. Some platforms - support SPI3 and some do not (still not clear). - * nuttx/configs/shenzhou: Various fixes to build new NxWM - configuration. - * configs/shenzhou: Oops. The Shenzhou LCD is and SSD1289, - not an ILI93xx. - * configs/shenzhou/src/up_ssd1289.c: The LCD is basically functional - on the Shenzhou board. - * graphics/nxmu: Correct some bad parameter checking that caused - failures when DEBUG was enabled. - * arch/arm/src/armv7-m/nvic.h: Add bit definitions for the AIRCR - register. - * drivers/input/ads7843.c: Need semaphore protection in logic - that samples the position. - * drivers/lcd/ssd1289.c: On some platforms we are unable to - read the device ID -- reason unknown; workaround in place. - * drivers/input/ads7843.c: Add thresholding options and an - option to swap X and Y positions. Fix some logic errors in - the SPI locking/selecting logic. - * arch/arm/src/armv7-m/up_systemreset.c: Add logic to reset - the Cortex-Mx using the AIRCR register. Contributed by Darcy - Gong. - * arch/arm/src/stm32/up_eth.c: Add logic specifically for the - DM9161 PHY. If the DM9161 failed to initialize, then use the - up_sysemreset() logic to reset the MCU. Contributed by Darcy - Gong. - * arch/arm/src/stm32/stm32_gpio.c: Add missing logic to set bit - for SPI3 remap. This fixes the XPT2046 touchscreen driver using - drivers/input/ads7843.c - * configs/shenzhou/src/up_ssd1289.c: Fix naming error in - conditional compilation. - * configs/shenzhou/nxwm/defconfig: Disable reading from the LCD. - This does not work. The hardware and the driver support the - capability, but there is some bug that causes memory corruption. - The work around for now: Just disable reading from the LCD. - * drivers/lcd/ssd1289.c: Add some logic to reduce the amount of - output when CONFIG_DEBUG_LCD is enabled. - * configs/shenzhou/nxwm/defconfig: Bug found and fixed... The - original configuration had too much stuff turned on. Reducing - stack sizes, some features, and buffer sizes made the - configuration reliable (Reading from the LCD is still disabled). - * net/uip/uip_icmpping.c: Fix problem that prevented ping from - going outside of local network. Submitted by Darcy Gong - -6.23 2012-11-05 Gregory Nutt - - * arch/arm/src/stm32/stm32_rng.c, chip/stm32_rng.h, and other files: - Implementation of /dev/random using the STM32 Random Number - Generator (RNG). - * board.h file for shenzhou, fire-stm32v2, and olimex-stm32-p107: - Add frequencies for HSE, HSI, LSE, and LSI. These are needed - by the STM32 watchdog driver. - * CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences - of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*. - * drivers/mtd/w25.c and configs/*/src/up_w25.c: Several fixes for the - W25 SPI FLASH. - * configs/*/Make.defs: All buildroot tools now use the extension - xxx-nuttx-elf- vs. xxx-elf- - * configs/shenzhou/*/Make.defs: Now uses the new buildroot 4.6.3 - EABI toolchain. - * lib/stdio/lib_libdtoa.c: Another dtoa() fix from Mike Smith. - * configs/shenzhou/src/up_adc.c: Add ADC support for the Shenzhou - board (Darcy Gong). - * configs/shenzhou/thttpd: Add a THTTPD configuration for the - Shenzhou board (Darcy Gong). - * include/termios.h and lib/termios/libcf*speed.c: The non-standard, - "hidden" c_speed cannot be type const or else static instantiations - of termios will be required to initialize it (Mike Smith). - * drivers/input/max11802.c/h, and include/nuttx/input max11802.h: Adds - support for the Maxim MAX11802 touchscreen controller (contributed by - Petteri Aimonen). - * graphics/nxtk/nxtk_events.c: Missing implementation of the blocked - method. This is a critical bugfix for graphics support (contributed - by Petteri Aimonen). - * drivers/usbdev/pl2303.c, drivers/usbdev/usbmsc.h, and - include/nuttx/usb/cdcacm.h: USB_CONFIG_ATTR_SELFPOWER vs. - USB_CONFIG_ATT_SELFPOWER (contributed by Petteri Aimonen). - * arch/arm/src/armv7-m/up_memcpy.S: An optimized memcpy() function for - the ARMv7-M family contributed by Mike Smith. - * lib/strings/lib_vikmemcpy.c: As an option, the larger but faster - implemementation of memcpy from Daniel Vik is now available (this is - from http://www.danielvik.com/2010/02/fast-memcpy-in-c.html). - * lib/strings/lib_memset.c: CONFIG_MEMSET_OPTSPEED will select a - version of memset() optimized for speed. By default, memset() is - optimized for size. - * lib/strings/lib_memset.c: CONFIG_MEMSET_64BIT will perform 64-bit - aligned memset() operations. - * arch/arm/src/stm32/stm32_adc.c: Need to put the ADC back into the - initial reset in the open/setup logic. Opening the ADC driver works - the first time, but not the second because the device is left in a - powered down state on the last close. - * configs/olimex-lpc1766stck/scripts: Replace all of the identical - ld.script files with the common one in this directory. - * configs/stm3220g-eval/scripts: Replace all of the identical - ld.script files with the common one in this directory. - * configs/hymini-stm32v/scripts: Replace all of the identical - ld.script files with the common one in this directory. - * configs/lpcxpresso-lpc1768/scripts: Replace all of the identical - ld.script files with the common one in this directory. - * binfmt/elf.c, binfmt/libelf, include/elf.h, include/nuttx/elf.h: Add - basic framework for loadable ELF module support. The initial check- - in is non-functional and is simply the framework for ELF support. - * include/nuttx/binfmt.h, nxflat.h, elf.h, and symtab.h: Moved to - include/nuttx/binfmt/. - * arch/sim/src/up_elf.c and arch/x86/src/common/up_elf.c: Add - for ELF modules. - * arch/arm/include/elf.h: Added ARM ELF header file. - * include/elf32.h: Renamed elf.h to elf32.h. - * configs/stm32f4discovery/ostest: Converted to use the new - Kconfig-based configuration system. - * configs/stm32f4discovery/elf and configs/stm32f4discovery/scripts/gnu-elf.ld - Add a configuration for testing the ARM ELF loader. - * binfmt/libelf: Can't use fstat(). NuttX does not yet support it. Damn! - * binfmt/libelf: The basic ELF module execution appears fully functional. - * configs/shenzhou/src/up_relays.c: Add support for relays from the - Shenzhou board. Contributed by Darcy Gong. - * lib/fixedmath: Moved the old lib/math to lib/fixedmath to make room for - the math library from the Rhombus OS - * lib/math: Now contains the math library from the Rhombus OS by Nick Johnson - (submitted by Darcy Gong). - * include/float.h: Add a first cut at the float.h header file. This - really should be an architecture/toolchain-specific header file. It - is only used if CONFIG_ARCH_FLOAT_H is defined. - * lib/math: Files now conform to coding standards. Separated float, - double, and long double versions of code into separate files so that - they don't draw in so much un-necessary code when doing a dumb link. - * binfmt/libelf: The ELF loader is working correctly with C++ static - constructors and destructors and all. - * Documentation/NuttXBinfmt.html: Add documentation of the binary loader. - * configs/sim/ostest: Converted to use the mconf configuration tool. - * configs/sim/cxxtest: New test that will be used to verify the uClibc++ - port (eventually). - * include/nuttx/fs/fs.h, lib/stdio/lib_libfread.c, lib_ferror.c, - lib_feof.c, and lib_clearerr.c: Add support for ferror(), feof(), - and clearerror(). ferror() support is bogus at the moment (it - is equivalent to !feof()); the others should be good. - * configs/stm32f4discovery/include/board.h: Correct timer 2-7 - base frequency (provided by Freddie Chopin). - * include/nuttx/sched.h, sched/atexit.c, and sched/task_deletehook.c: - If both atexit() and on_exit() are enabled, then implement atexit() - as just a special caseof on_exit(). This assumes that the ABI can - handle receipt of more call parameters than the receiving function - expects. That is usually the case if parameters are passed in - registers. - * libxx/libxx_cxa_atexit(): Implements __cxa_atexit() - * configs/stm32f4discovery/cxxtest: New test that will be used to - verify the uClibc++ port (eventually). The sim platform turned not - to be a good platform for testing uClibc++. The sim example will not - run because the simulator will attempt to execute the static - constructors before main() starts. BUT... NuttX is not initialized - and this results in a crash. On the STM324Discovery, I will have - better control over when the static constructors run. - * RGMP 4.0 updated from Qiany Yu. - * configs/*/Make.defs and configs/*/ld.script: Massive clean-up - and standardization of linker scripts from Freddie Chopin. - * net/netdev_ioctl.c: Add interface state flags and ioctl calls - to bring network interfaces up and down (from Darcy Gong). - * config/stm32f4discovery: Enable C++ exceptions. Now the entire - apps/examples/cxxtest works -- meaning that the uClibc++ is - complete and verified for the STM32 platform. - -6.24 2012-12-20 Gregory Nutt - - * arch/arm/src/stm32: Support for STM32F100 high density chips - added by Freddie Chopin. - * configs/stm32f100_generic: Support for generic STM32F100RC board - contributed by Freddie Chopin. - * arch/arm/src/stm32_otgfsdev.c: Partial fix from Petteri Aimonen. - * drivers/lcd/ug-2864ambag01.c and include/nuttx/lcd/ug_2864ambag01.h: - LCD driver for the Univision OLED of the same name (untested on - initial check-in). - * configs/stm32f4discovery/nxlines: Configure to use mconf/Kconfig - tool. - * configs/stm32f4discovery/src/up_ug2864ambag01.c: Board-specific - initialization for UG-2864AMBAG01 OLED connecte to STM32F4Disovery. - * libxx/libxx_stdthrow.cxx: Exception stubs from Petteri Aimonen. - * configs/stm32f4discovery/src/up_ug2864ambag01.c: Driver has been - verified on the STM32F4Discovery platform. Some tuning of the - configuration could improve the presentation. Lower resolution displays - are also more subject to the "fat, flat line bug" that I need to fix - someday. See http://www.nuttx.org/doku.php?id=wiki:graphics:nxgraphics - for a description of the fat, flat line bug. - * libc: Renamed nuttx/lib to nuttx/libc to make space for a true lib/ - directory that will be forthcoming. Also rename libraries: liblib.a -> libc.a, - libulib.a -> libuc.a, libklib.a -> libkc.a, liblibxx.a ->libcxx.a. - (I will probably, eventually rename libxx to libcxx for consistency) - * Makefile, lib/: A new, empty directory that will hold generated libraries. - This simplifies the library patch calculations and lets me get rid of some - bash logic. The change is functional, but only partially complete; - additional logic is needed in the arch/*/src/Makefile's as well. Right - now that logic generate multiple library paths, all pointing to the lib/ - directory. - * arch/*/src/Makefile: Now uses only the libraries in lib/ - Replace bash fragments that test for board/Makefile. - * Makefile.win: The beginnings of a Windows-native build. This is just - the beginning and not yet ready for prime time use. - * configs/stm32f4discovery/winbuild: This is a version of the standard - NuttX OS test, but configured to build natively on Windows. Its only - real purpose is to very the native Windows build logic. - * tools/mkdeps.bat and tools/mkdeps.c: mkdeps.bat is a failed attempt - to leverage mkdeps.sh to CMD.exe. It fails because there are certain - critical CFLAG values that cannot be passed on the CMD.exe command line - (like '='). mkdeps.c is a work in progress that will, hopefully, - replace both mkdeps.sh and mkdeps.bat. - * tools/Config.mk: Centralize the definition of the script that will be - used to generated header file include paths for the compiler. This - needs to be centralized in order to support the Windows native build. - * tools/incdir.bat: A replacement for tools/incdir.sh for use with the - the Windows native build. - * Makefile.unix: The existing top-level Makefile has been renamed - Makefile.unix. - * Makefile: This is a new top-level Makefile that just includes - either Makefile.unix or Makefile.win - * configs/stm3240g-eval/src: Qencoder fixes from Ryan Sundberg. - * arch/arm/src/stm32/stm32_qencoder.c: TIM3 bug fix from Ryan Sundberg. - * tools/mkromfsimg.sh: Correct typo in an error message (Ryan Sundberg) - * arch/*/src/Makefile: Remove tftboot install and creation of System.map - for Windows native build. The first is a necessary change, the second - just needs re-implemented. - * configs/mirtoo: Update Mirtoo pin definitions for Release 2. Provided - by Konstantin Dimitrov. - * Fixed an uninitialized variable in the file system that can cause - assertions if DEBUG on (contributed by Lorenz Meier). - * Config.mk: Defined DELIM to be either / or \, depending upon - CONFIG_WINDOWS_NATIVE. This will allow me to eliminate a lot of - conditional logic elsewhere. - * nuttx/graphics: One a mouse button is pressed, continue to report all - mouse button events to the first window that received the initial - button down event, even if the mouse attempts to drag outside the - window. From Petteri Aimonen. - * nuttx/graphics/nxmu/nx_block.c: One more fix to the NX block message - logic from Petteri Aimonen. - * include/nuttx/wqueue.h: Some basic definitions to support a user- - space work queue (someday in the future). - * graphics/nxmu: Add semaphores so buffers messages that send buffers - will block until the buffer data has been acted upon. - * graphics/nxmw: Extended the blocked messages to cover mouse movement - and redraw events. These will also cause problems if sent to a window - while it is closing. - * arch/several: Change UARTs are enabled for i.MX, LM3S, eZ80, and M16C to - match how they are enabled for other architectures. - * configs/ez80f910200kitg: Convert to use mconf configuration. - * sched/pause.c: Implements the POSIX pause() function. - * eZ80: Lots of changes to eZ80 configurations and build logic as I - struggle to get a clean Windows build (still not working). - * configs/cloudctrl: Darcy Gong's CloudController board. This is a - small network relay development board. Based on the Shenzhou IV development - board design. It is based on the STM32F107VC MCU. - * arch/arm/src/stm32_serial.c and stm32_lowputc.c: Added optional RS-485 - direction bit control. From Freddie Chopin. - * Lots of build files: ARMv7-M and MIPS32 Make.defs now include a common - Toolchain.defs file that can be used to manage toolchains in a more - configurable way. Contributed by Mike Smith - * configs/stm32f4discovery/winbuild and configs/cloudctrl: Adapted to use - Mike's Toolchain.defs. - * tools/configure.sh: Adapted to handle paths and setenv.bat files correctly - for native Windows builds. - * More of build files: AVR and AVR32 Make.defs now include a common - Toolchain.defs file that can be used to manage toolchains in a more - configurable way. Contributed by Mike Smith - * tools/incdir.sh and incdir.bat: Add -s option to generate system header - file paths. - * nuttx/arch/arm/src/arm/Toolchain.defs: Add support for more ARM toolchains - (from Mike Smith). - * arch/arm/src/stm32/stm32f40xxx_rcc.c: Enabled FLASH prefetch (from Petteri - Aimonen). - * graphics/nxtk/nxtk_filltrapwindow.c: Correct an offset problem (from - Peterri Aimonen). - * graphics/nxglib/nxglib_splitline.c: Fix error in drawing of near horizontal - lines (from Peterri Aimonen). - * sched/task_exithook.c: Missing right bracket with certain conditional - compilation (thanks James Goppert). - * arch/arm/srch/stm32/stm32_otgfshost.c: Replace timeout handling; use - system tick instead of frame counter. The frame counter gets reset to - zero at 0x3fff making it error prone. - * arch/arm/src/stm32/stm32f20xx_rcc.c and stm32f40xx_rcc.c: Added option - CONFIG_STM32_FLASH_PREFETCH. FLASH prefetch will now only be enabled - if this option is selected. - * configs/ez80f910200zco/ostest: Now uses Kconfig/mconf configuration - tool. Updated to build in native Windows environment. Other ez80f910200zco - build scripts also updated. - * configs/z8f64200100kit/ostest: Update to same level as eZ80 configurations. - * nuttx/configs/z8f64200100kit/scripts/setenv.bat: Add support for native - Windows build. - * nuttx/arch/arm/src/lpc17xx/lpc17_i2c.c: Resources not being released when - I2C is uninitialized. - * cloudctrl/src/up_chipid.c and shenzhou/src/up_chipid.c: Add functions to - get chip ID. Contributed by Darcy Gong. These should not be board-dependent, - but should be in arch/arm/src/stm32 where they can be used from any board. - * sched/work_thread.c: Fix backward conditional compilation. This might - has caused a memory leak. From Freddie Chopin. - * configs//Make.defs: Fix typo -wstrict-prototypes should be - -Wstrict-prototypes (From Denis Carilki). - * arch/arm/src/calapyso/calypso_keypad.c: Add Calypso keypad driver. From - Denis Carilki. - * z8encore000zco/ostest and z8f64200100kit/ostest: Converted to use Kconfig/ - mconf configuration tool. - * arch/arm/src/armv7-m/up_exception.S: missing curly braces for push/pop - From Freddie Chopin. - * z8encore000zco/ostest and z8f64200100kit/ostest: Can now be modified to - support the Windows native builds (see corresponding README.txt files). - * configs/z16f2800100zcog - All configurations updated to use the ZDS-II - 5.0.1 toolchain. - * configs/z16f2800100zcog - All configurations updated to use Kconfig/mconf - configuration tools. - * configs/z16f2800100zcog/ostest - Now supports a native Windows build - (other ZNEO configs may also support the native build, but this has not - been verfiied). - * include/nuttx/input/keypad.h, arch/arm/src/calypso/calypso_keypad.c, and - configs/compal_e99/nsh_highram: First cut at a standard keypad interface - definition. Contributed by Denis Carikli. - * libc/stdlib/lib_rand.c: Always add one to result congruential generators - to avoid the value zero. Suggested by Freddie Chopin. - * tools/b16.c: Fixed precision math conversion utility. - * graphics/nxglib/nxglib_splitline.c: Fix the "fat, flat line bug" - * arch/z80/src/*/Toolchain.defs: Add dummy Toolchain.defs files for the - z80 family. - * configs/z80sim/ostest: Converted to build with the Kconfig/mconf tool. - Current configuration failed to build for me (Ubuntu 12.10, SDCC 3.2.0 - pre-built for Linux) due to a glibc memory corruptionerror in SDCC. - * configs/z80sim/ostest: Default is now the Windows native build. See - configs/z80sim/README.txt for instructions to convert back to a Linux or - or Cygwin build. - * arch/z80/src/Makefile.sdccw: Renamed makefiles with extensions zdiil, - zdiiw, sdccl, and sdccw for the ZDS-II vs SDCC compilers and for the - POSIX vs Windows native builds. - * nuttx/drivers/mtd/ftl.c: Fix for the flash translation layer. Short - unaligned writes were buggy. From Petteri Aimonen. - * nuttx/libc/math/lib_round*.c: Add rounding functions to the math - library. Contributed by Petteri Aimonen. - * include/cxx/cstdlib: Add stroul(). From Petteri Aimonen. - * arch/*/include/limits.h: Change signed minimum values from, for example, - (-128) to (-127 - 1) to avoid overflows under certain conditions. From - Peterri Aimonen. - * graphics/nxtk/nxtk_subwindowmove.c: Previously it was very difficult to - do e.g. "scroll by dx, dy". When given the full window area, nxtk_subwindowmove - would clip the offset always to 0,0. It makes more sense for it to clip the - source area and not modify the offset. From Petteri Aimonen. - * graphics/nxtk/nxtk_getwindow.c: Clipping would change the offset of returned - data, and caller has no way to know what the new offset would be. This messes - up font drawing when the text is partially out of window, e.g. when scrolling. - Also from Petteri Aimonen. - * include/stdbool.h: Can now be disabled for C++ files if CONFIG_C99_BOOL8 is - defined. CONFIG_C99_BOOL8 indicates (1) that the sizeof(_Bool) is one in both - C and C++, and (2) the C compiler is C99 and supports the _Bool intrinsic - type. Requested by Freddie Chopin. - * include/stdlib/lib_rand.c: Various additional changes so that the integer - value zero can be returned. Requested by Freddie Chopin. - * arch/z80/src/Makefile.sdcc*, z80/up_mem.h: Redesign Z80 build so that it - no longer depends on Bash scripts. - * configs/z80sim/nsh and pashello: Converted to (1) use the kconfig-frontends - configuration tool, and (2) to build natively under Windows. The NSH - configuration is verified; the pashello configuration needs a more TLC. - * tools/copydir.sh: Rename tools/winlink.sh to tools/copydir.sh - * tools/link.bat, unlink.bat, and copydir.bat: Add Windows counterparts - to the link.sh, unlink.sh, and copydir.sh Bash scripts. - * configs/z80sim/pashello: Now builds correctly. - * configs/xtrs/ostest, nsh, and pashello: Converted to (1) use the kconfig- - frontends configuration tool, and (2) to build natively under Windows. - * drivers/serial/Kconfig and sched/Kconfig: Two names for same configuration: - CONFIG_LOWLEVEL_CONSOLE is bogus and CONFIG_DEV_LOWCONSOLE is in the wrong - Kconfig file. Moved to drivers/serial/Kconfig replacing CONFIG_LOWLEVEL_CONSOLE. - * arch/z80/include/z180: Add header files for z180 chips. Initial versions - are just clones of z80 header files. - * arch/z80/src/z180: Add source files for z180 chips. Initial versions - are just clones of z80 source files. - * include/nuttx/arch.h: Add address environment control interfaces (for use - with CPUs the provide MCUs and support process-like address environments). - * arch/z80/src/z180/z180_mmu.*: Add MMU support for z180 tasks. - * configs/p112: Add very basic board support and an examples/ostest - configuration for the venerable P112 board. - * sched/os_bringup.c: If CONFIG_PATH_INITIAL is defined, then the initial - environment of the task started by os_bringup() will have the PATH - environment variable defined to be that string. - * binfmt/binfmt_exepath.c: If CONFIG_BINFMT_EXEPATH is defined, then this - file will be built. It contains logic to search for regular files at - the absolutes paths found in the current PATH environment variable - setting. This is untested and not yet hooked into the binfmt exec() - logic on initial check-in - * binfmt/binfmt_loadmodule.c: load_module() will now traverse the PATH - variable to locate files from their relative path. - * include/nuttx/arch.h and arch/z80/src/z180/z180_mmu.c: Restructure the - address environment interfaces so that they will better integrate with - binfmt/. - * binfmt/libelf/*, binfmt/libnxflat/* and other files: Integrate the - address environment interfaces. If CONFIG_ADDRENV=y, then binfmt/ - will now create an address environment for new tasks (instead of - just malloc'ing the task memory). - * configs/stm32f4discovery/elf: Enable support/test of the PATH - to find executables using a relative path. - -6.25 2013-02-01 Gregory Nutt - - * graphics/: Adds 5x8 monospace font. This tiny font is useful for graph - labels and for small bitmapped display. Contributed by Petteri - Aimonen. - * configs/stm3220g-eval/nxwm: Converted to use the kconfig-frontends - configuration tool. - * configs/sim/nxwm: Converted to use the kconfig-frontends configuration - tool. - * include/pthread.h: In sys/prctl.h because it is needed by - pthread_[set|get]name_np() - * tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell. - * sched/sig_timedwait.c: Should always move the time up to the next - largest number of system ticks. The logic was rounding. Noted by - Petteri Aimonen. - * arch/arm/src/up_head.S: Fix backward conditional compilation. NOTE - there is a issue of ARM9 systems with low vectors and large memories - that will have to be addressed in the future. - * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Add logic to marshal - and serialize speical keyboard commands intermixed with normal ASCII - data (not yet hooked into anything). - * drivers/usbhost/usbhost_hidkbd.c: If CONFIG_HIDKBD_ENCODED is - defined, this driver will now use libc/misc/lib_kbdencode.c to - encode special function keys. - * configs/olimex-lpc1766stk/hidkbd: This configuration has been - converted to use the kconfig-frontends configuration tool. - * drivers/lcd/ug-2864hsweg01.c and include/nuttx/lcd/ug-2864hsweg01.h: - Driver for UG-2864HSWEG01 OLED contributed by Darcy Gong. - * configs/stm32f4discovery/src/up_ug2864hsweg01.c: Support for the - UG-2864HSWEG01 OLED for the STM32F4Discovery board. - * drivers/usbhost/usbhost_hidkbd.c: Correct a logic error in how - tasks waiting for read data are awakened. - * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Now handles keypress - events too. However, the USB HID keyboard driver has not yet been - updated to detect key release events. That is kind of tricky in - the USB HID keyboard report data. - * configs/mcu123-214x/nsh: Converted to use the kconfig-frontends - configuration tool. - * configs/zp214xpa: Add basic support for the The0.net ZP213x/4xPA - board (with the LPC2148 and the UG_2864AMBAG01). - * configs/sim/nxlines: Add an nxlines configuration for the - simulator. - * configs/zp214xpa/nxlines: Add an nxlines configuration for the - ZP213x/4xPA (with the LPC2148 and the UG_2864AMBAG01). Working - as of 2012-12-30. - * configs/olimex-lpc1766stk/wlan: Remove non-functional - configuration. - * configs/stm32f4discovery/src and nuttx/drivers/lcd/ug-2864hsweg01.c: - Updates and corrections for the UG-2864HSWEG01 from Darcy Gong. - * configs/lm326965-ek: All configurations converted to use the - kconfig-frontends configuration tool. - * configs/Kconfig: NSH_MMCSDSPIPORTNO should depend on MMCSD_SPI, - not just SPI (from Jose Pablo Carballo). - * arch/arm/src/arm/Kconfig and armv7m/Kconfig: Add an option for - buildroot toolchains: They may be EABI or OABI. - * include/nuttx/progmem and arch/arm/src/stm32/stm32_flash.c: - Fix a counting bug plus change interface to use either relative - or absolute FLASH addressing (from Freddie Chopin). - * libc/misc/Make.defs: Fix error in conditional for KBD CODEC. - * libc/Kconfig and configs/*/defconfig (several): The default - setting should be CONFIG_LIB_KBDCODEC=n - * tools/configure.c: configure.c can be used to build a work-alike - program as a replacement for configure.sh. This work-alike - program would be used in environments that do not support Bash - scripting (such as the Windows native environment). - * tools/configure.bat: configure.bat is a small Windows batch - file that can be used as a replacement for configure.sh in a - Windows native environment. configure.bat is actually just a - thin layer that executes configure.exe if it is available. If - configure.exe is not available, then configure.bat will attempt - to build it first. - * arch/arm/src/lpc17xx/lpc17_syscon.h: Correct some typos in bit - definitions (from Rommel Marcelo). - * libc/string/lib_strndup.c: strndup() should use strnlen(), not - strlen(), to determine the size of the string. - * sched/os_bringup.c: Remove support for CONFIG_BUILTIN_APP_START. - This is not really a useful feature and creates a violation of the - OS layered architecture. - * include/unistd.h, arch/arch/src/*: Implement a simple vfork(). - On initial checkin, this API is available only for ARM platforms. - * binfmt/binfmt_exec.c: exec() now sets the priority of the new task - to the same priority as the current task (instead of the arbirtrary - value of 50). - * libc/unisted/lib_execv.c and lib_execl.c: New, somewhat flawed, - implementations of execv() and execl(). - * tools/cfgdefine.c: Strips quotes from CONFIG_EXECFUNCS_SYMTAB - value. - * arch/arm/include/lm3s/chip.h: Move chip definitions into - public include area for compatibility with other architectures. - * arch/arm/src/lm3s/chip: Move register definition header files - into a new chip/ sub-directory. - * arch/arm/src/lm3s/lm3s_internal.h: Broke up into several - smaller header files. - * arch/arm/src/lm: Rename the arch/arm/src/lm3s directory to - arch/arm/src/lm so that is can support other members of the - Stellaris family. - * libc/spawn: Add file action interfaces needed by posix_spawn(). - * sched/clock_time2ticks.c: Another case where time was being - rounded down instead of up (from Mike Smith). - * libc/spawn: Implementation of posix_spawn() is complete but - untested and undocumented. - * drivers/usbdev/pl2303.c: Fix typols in the PL2303 driver - (from Max Holtzberg). - * configs/stm32f4discovery/posix_spawn: Added a configuration - that can be used for testing posix_spawn(). - * arch/arm/src/stm32: Bring F1 support for general DMA and serial - DMA in paricular up to parity with F2/F4 (from Mike Smith). - * libc/stdio/lib_libfread.c: Correct some error handling when - lib_fread() was passed a bad stream. Needed to move the - releasing of a semaphore inside of some conditional logic - (cosmetic). - * include/nuttx/sched.h, sched/task_setup.c, and sched/task_exithook.c: - Add support for remembering the parent task and sending - SIGCHLD to the parent when the task exists. - * sched/task_exithook.c: Fixed a *critical* bug. Here is - the scenario: (1) sched_lock() is called increments the lockcount - on the current TCB (i.e., the one at the head of the ready to run - list), (2) sched_mergepending is called which may change the task - at the head of the ready-to-run list, then (3) sched_unlock() is called - which decrements the lockcount on the wrong TCB. The failure case - that I saw was that pre-emption got disabled in the IDLE thread, - locking up the whole system. - * sched/sched_waitpid.c: Use SIGCHLD instead of a semaphore. This - is a much more spec-compliant implementation. However, there are - some issues with overrunning signals because NuttX does not support - queueing of signals (POSIX does not require it). I think it may - need to. - * sched/sched_waitid.c and sched_wait.c: Add support for waitid() - and wait(). See issues with waitpid() above. - * include/nuttx/fs/fs.h and fs/fs_files.c: Add a dup() method to - the struct mountpt_operations. When dup'ing a file that resides - on a mounted volume, let the file system's dup() method do the - work. - * fs/romfs/fs_romfs.c: Implemented the dup() method for the ROMFS - file system. - * fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and - fs/nfs/nfs_vfsops.c: Add hooks for dup() method (not yet - implemented). - * fs/romfs: Remove the rf_open flag. It looks good, but actually - does nothing. - * fs/fat: Remove the ff_open flag. Same story as for the ROMFS - rf_open flag. - * fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and - fs/nfs/nfs_vfsops.c: Completed implementation of the dup() methods. - There is still no good test available. - * sched/sig_timedwait.c: sigtimedwait() would return a bad signal - number if the signal was already pending when the function was - called. - * configs/ubw32/scripts: All common linker scripts moved to this - scripts sub-directory - * configs/ubw32/ostest: Configuration configured to use the - kconfig-frontends tools. - * arch/mips/src/mips32/up_vfork.c, up_vfork.h, and vfork.S: - Implement vfork() for MIPS32 (no floating point support) - * configs/ubw32/ostest: Enable the vfork() test. - * fs/binfs: Move apps/builtin/binfs.c to fs/binfs/fs_binfs.c - CONFIG_APPS_BINDIR rename CONFIG_FS_BINFS - * include/nuttx/binfmt/builtin.h: Some of the content of - apps/include/apps.h moved to include/nuttx/binfmt/builtin.h - * binfmt/libbuiltin/libbuiltin_utils.c: Move builtin - utility functions from apps/builtin/exec_builtins.c to - binfmt/libbuiltin/libbuiltin_utils.c - * binfmt/builtin.c and binfmt/libbuiltin: Add a binary "loader" - that can be used to execute builtin programs from the BINFS - file system. - * configs/sim/nsh: Convert to use kconfig-frontends configuration - tool. - * binfmt/binfmt_schedunload.c: Add logic based on SIGCHLD to - automatically unload and clean-up after running a task that - was loaded into memory. - * binfmt/libbuiltin: Extensions from Mike Smith - * sched/task_reparent.c: Add internal interface to change the - parent task. - * sched/task_posixspawn(): Move libc/spawn/lib_ps.c to - sched/task_posixspawn() now it requires internal, reparenting - interfaces - * include/nuttx/spawn(): Move libc/spawn.h to include/nuttx/spawn.h - * arch/arm/include/lpc17xx/chip.h, irq178x.h: Integrate Marcelo - Rommel's LPC1788 definitions into the base LPC17xx. - * configs/olimex-lpc1766stk/nsh: Convert configuration to use - the kconfig-frontends tools. - * sched/task_reparent.c: Simplify reparenting interface. - * arch/arm/src/[many]: More LPC1788 definitions from Rommel - Marcelo incorporated. - * configs/open1788: Board configuration for the Wave Share - Open1788 board. Still fragmentary (contributed by Rommel - Marcelo, adapted to use kconfig-frontends. - * net/send(): Add logic to work around delayed ACKs by splitting - packets (contributed by Yan T.). - * net/recvfrom(): Fix a bug. When the host closes a connection - (gracefully). recv[from]() returned success and the closure - was never detected. Hmmm.. I don't know why the network monitor - did not catch this event. This is an important bug fix. - * net/recvfrom(): Fix a introduced with the last bugfix. If - the peer does an orderly closure of the socket, report 0 not - -ENOTCONN - * configs/lm3s6965-ek/README.txt and tools/: Add an OpenOCD - configuration for the LM3S (from Jose Pablo Carballo). - * nuttx/lcd/hd4478ou.h and configs/pcblogic-pic32mx/src/up_lcd1602: - Start of support of LCD1602 alphanumeric LCD. I need a few - more parts before I can finish integrating this one. - * arch/arm/src/*/chip.h and arch/arm/include/*/chip.h: Move all - priority ranges from the src to the include chip.h header file. - * arch/arm/include/armv7-m/irq.h: Add inline functions to enable - and disable interrupts via the BASEPRI register. - * arch/arm/Kconfig: Add new option CONFIG_ARM7VM_USEBASEI - * arch/arm/src/*/*_irq.c: Set the priority of the SVCALL exception - to the highest possible value. - * arch/armv7-m/up_hardfault.c: Fail if a hardfault occurs - while CONFIG_ARM7VM_USEBASEPRI=y. - * arch/arm/src/stm32/stm32_serial.c: Add support for USART - single wire mode (Contributed by the PX4 team). - * sched/: Implement support for retaining child task status after - the child task exists. This is behavior required by POSIX. - But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and - CONFIG_SCHED_CHILD_STATUS - * Add support for keyboard encode to the keypad test (from - Denis Carikli). - * configs/olimex-lpc1766stk/nettest: Configuration converted to - use the kconfig-frontends tools. - * net/net_poll.c: Split net_poll() to create psock_poll() too. - * net/net_poll.c: Fix poll/select issure reported by Qiang: - poll_interrupt() must call net_lostconnection() when a - loss of connection is reported. Otherwise, the system will - not know that the connection has been lost. - * sched/group_create.c, group_join.c, and group_leave.c: Add - support for task groups. - * sched/group_signal.c and task_exithook.c: Send signal to all - members for the parent task group. - * include/nuttx/sched.h and sched/env_*.c: Move environment - variables into task group structure. - * sched/: Lots of file changed. Don't keep the parent task's - task ID in the child task's TCB. Instead, keep the parent - task group IN the child task's task group. - * fs/, sched/, include/nuttx/sched.h, and include/nutts/fs/fs.h: - Move file data from the TCB to the task group structure. - * libc/stdio/, sched/, include/nuttx/lib.h, and include/nutts/fs/fs.h: - Move stream data from the TCB to the task group structure. - * net/, sched/, and include/nuttx/net/net.h: Move socket data - from the TCB to the task group structure. - * sched/task_starthook.c, sched/task_start.c, and include/nuttx/sched.h: - Add a task start hook that will be called before the task main - is started. This can be used to schedule C++ constructors to run - automatically in the context of the new task. - * binfmt/binfmt_execmodule: Execute constructors as a start hook. - * sched/os_start.c: Fix ordering of group initialization. - * configs/stm32f4discovery/usbnsh: Add an NSH STM32F4Discovery - configuration that uses USB CDC/ACM for the NSH console. - * configs/stm32f4discovery/nsh: Converted to use the kconfig-frontends - tools. - * configs/*/src/up_userleds.c: Fix a error that was cloned into - all STM32 user LED code. The wrong definitions were being used - to set LEDs on or off. - * arch/*/common/up_internal.h and arch/*/common/up_initialize.c: - Serial was driver was not being built if there is no console - device. Obviously, the serial driver may be needed even in - this case. - * arch/arm/src/stm32/stm32_serial.c: If there is a serial console, - it would be ttyS0 and the others would be ttyS1-5. If there - is not serial console, was labeling them ttyS1-6; now labels them - ttyS0-5. - * fs/fs_syslog.c: Can't handle SYSLOG output to character device from - the IDLE task (because it can't block). syslog_putc now returns EOF - on failure and sets errno. Fixed some errors in error handling. - * libc/stdio/lib_syslogstream.c: Checking of return value from - syslog_putc was bogus. Switching to EOF for all errors solves - this. - * arch/arm/src/lm/chip/lm4f_memorymap.h: More LM4F changes from - Jose Pablo Carballo. - * drivers/serial/serial.c, include/nuttx/serial/serial.h, - drivers/usbdev/cdcacm.c, and drivers/pl2303.c: Add support for - removable serial devices (like USB serial). This support is enabled - by CONFIG_SERIAL_REMOVABLE. - * arch/*/src/*/Toolchain.defs: Change assignment so that we can - override CROSSDEV with a make command line argument. - * include/assert.h: Mark assertion functions as non-returning. - * arch/*/src/*/up_assert.h: Mark _up_assert() as non-returning. - * drivers/mtd/at25.c: When the AT25 device was not available the - initialization did not fail like it should. From Petteri Aimonen. - * fs/fat/fs_configfat.c: Fix some errors in FAT formatting logic - for large devices and for FAT32. From Petteri Aimonen. - * fs/fat/fs_fat32util.c: Fix an initialization error found by - Petteri Aimonen. freecount and next freecount initialization were - reversed. - * drivers/mmcsd/mmcsd_spi.c: Some SD cards will appear busy until - switched to SPI mode for first time. Having a pull-up resistor on - MISO may avoid this problem, but this patch makes it work also - without pull-up. From Petteri Aimonen. - * fs/fat/fs_fat32.c: Fix a compilation error when FAT_DMAMEMORY=y. - From Petteri Aimonen. - * arch/arm/src/stm32/chip/stm32_spi.h: STM32F4 max SPI clock freq is - 37.5 MHz. Patch from Petteri Aimonen. - * arch/arm/src/stm32/stm32_spi.c: Fixes for SPI DMA work on the - STM32F4. Includes untested additions for the F1 implementation as - well. From Petteri Aimonen. - -6.26 2013-03-15 Gregory Nutt - - * drivers/serial/serial.c: Correct some race conditions when checking - for disconnection of a removable serial device. - * sched/task_posixspawn.c, task_spawn.c, task_spawnparms.c and - spawn_internal.h: Create new interface task_spawn() that is - like posix_spawn(), but uses entry point addresses like - task_create(). - * Corrected all argv[] arguments. Should be char * const *, not - const char **. - * sched/pthread* and include/nuttx/sched: Move pthread join data - and pthread key calculation data into the "task group" structure. - * sched/atexit.c, on_exit.c, task_exithook.c and include/nuttx/sched.h: - Move atexit and on_exit data structures to task group. These - callbacks are only issued now when the final member of the task - group exits. - * sched/waitpid.c, task_exithook.c and include/nuttx/sched.h: - Move waitpid data data structures to task group. Callers of - of waitpid() are now only awakened when the final thread of the - task group exits. - * sched/mq_descreate.c, mq_open.c, mq_remove.c, group_leave.c, and - include/nuttx/sched.h: Move list of opened message queues to - the task group structures. Now all message queues opened by - members of the group are closed when the last member of the group - exits. - * includes/nuttx/sched.h and Lots of files: Change name of _TCB to - struct tcb_s so that (1) it is consitent with other NuttX naming and - so that (2) the naming can handle some upcoming changes. - * includes/nuttx/sched.h and sched/: There are three TCB structures: - struct tcb_s is a generic common version, struct task_tcb_s is a - version for tasks and kernel threads and pthread_tcb_s is a version - for pthreads. By dividing the TCB structure into these variants, - pthreads do not have to be burdened by task-specific data structures - (and vice versa). - * sched/task_exithook.c adn group_create.c: Fix an error, the - task within the task group may exit early leaving a pthread to - exit the task group last. In this case, we need to remember the - the PID of the main task in the task group and use that PID for - signalling SIGCHILD to the parent task group. - * included/nuttx/sched.h and sched/sig*.c: Numerous changes to the - signal deliver logic so that the delivery of signals to threads - within a task group will be compliant with delivery of signals - to threads within a POSIX process. - * sched/mq_recover.c and task_exithook.c: Add logic to handle the - case where a task is deleted (or pthread canceled) while it is - waiting on a message queue. task_delete() and pthread_cancel() - are dangerous interfaces. This is only one feeble recover measure - of *many* that would be needed to do this safely. - * sched/group_killchildren.c, task_recover.c, group_foreachchild.c, - sched/restart.c, sched/task_delete.c, and others: Beef up logic - to better support task deletion and pthread cancellation. Needed - to pass need OS test case for task_restart(). - * sched/include/sched.h and all timed functions in sched/: Move - timer from local variables to TCB. This is needed so that if a - task is canceled or restarted while it is waiting for a timed - event, we can gracefully recover. We can't let the timer expire - after the task has been deleted. - * arch/arm/include/stm32 and arch/arm/src/stm32: Add support for - the STM32 F3 family (still missing some things). - * configs/stm32f3discovery: This will (eventually) be support for - the STM32F3Discovery board. - * STM32 F3 and STM32F3Discovery port is complete a ready for test. - * arch/arm/src/lpc17xx: Add support for the Cortex-M4 FPU and - Mikes "common vector" logic. The LPC1788 is going to need - these things. - * arch/arm/src/stm32/stm32_spi.c: Fix SPI DMA logic that does - not work if sem_wait() is interrupt by a signal. From Petteri - Aimonen. - * drivers/input/max11802.c: MAX11802: Fix a timing bug that - corrupted coordinates. From Petteri Aimonen. - * drivers/mmcsd/mmcsd_spi.c: Use SPI locking so that MMC/SD can - exist on the same bus as other SPI devices. From Petteri - Aimonen. - * graphics/nxfonts/nxfonts_sans17x22.h: Small mod to hyphen in - sans17x22 font. The hyphen did not have any space on its sides. - This caused it to run together with other characters so that for - example "+-" would look weird. From Petteri Aimonen. - * mm/mm_mallinfo.c: Take MM semaphore in mm_mallinfo. From Petteri - Aimonen. - * configs/stm32f3discovery/nsh/defconfig: Disable SPI. It is not - used. - * drivers/mtd/sst39vf: Add a driver for the SST29VF NOR FLASH parts. - * sched/os_start.c: Add an additional call-out to support board- - specific driver initialization during the start phase: If - CONFIG_BOARD_INITIALIZE is defined, then an additioinal - initialization function called board_initialize() will be called - just after up_initialize() is called and just before the initial - application is started. - * arch/arm/src/stm32/stm32_otgfsdev.c, drivers/usbdev/usbdev_trprintf.c, - and include/nuttx/usb/usbdev_trace.h: Add logic to support decoding - of device-specific trace events to make the trace output more readable. - From Petteri Aimonen. - * arch/arm/src/stm32/stm32_otgfsdev.c: Need to manually set CNAK in - the case where we are waiting for a SETUP command with DATA. Otherwise, - the core may NAK further transactions. From Petteri Aimonen. - * arch/arm/src/stm32/stm32_otgfsdev.c: Add logic to prevent premature - to IDLE state. This change (plus the previous) was necessary to get - the CDC/ACM driver working the certain STM32 F4 hardware (but not others). - These changes appear to prevent certain race conditions that may or may - not cause USB problems. From Petteri Aimonen. - * arch/arm/include/armv6-m and arch/arm/src/armv6-m: First cut at support - for the Cortex-M0 - * configs/nutiny-nuc120, arch/arm/include/nu1xx, and arch/arm/src/nuc1xx: - Support for Nuvoton NuTiny NUC120. - * 2013-02-22: the Cortex-M0, NuvoTron NUC1xx, and NuTiny-SDK-NUC120 port - is code complete and ready for testing. - * configs/ekk-lm3s9b96/ostest and nsh: All EKK-LM3S9B96 configurations - converted to use the mconf configuration tool. - * configs/zkit-arm-1769: Add support for Zilogic System's ARM development - Kit, ZKIT-ARM-1769. From Rashid. - * configs/zkit-arm-1769/hello: Add a "Hello, World!" configuration for - the KBIT-ARM-1769 board. From Rashid. - * configs/zkit-arm-1769/thttpd: Add a THTTPD configuration for the - KBIT-ARM-1769 board. From Rashid. - * 2013-02-27: All configurations for the Cortex-M0 NuTINY-SDK-NUC120 - appear to be functional and stable. - * configs/zkit-arm-1769/nsh: Add an NSH configuration for the - KBIT-ARM-1769 board. From Rashid. - * arch/arm/src/stm32/stm32_otgfsdev.c: Fixes from Petterri Aimonen - related to corner cases that can cause infinite interrupts. - * drivers/usbdev/usbmsc_scsi.c: Change to allow the full name in the - USB descriptor but a truncated, 8-byte name in the SCSI field. - From Petteri Aimonen. - * arch/arm/src/stm32/stm32_spi.c: Need to clear error flags to prevent - corruption of subsequent transfers. Also, bit count should not be - changed while the SPI peripheral is enabled. From Petteri Aimonen. - * drivers/mmcsd/mmcsd_spi.c: When bus is shared, the speed has to be - set every time. Also SD cards require a few dummy clocks to react - into CS release. From Petteri Aimonen. - * configs/lm4f120-launchpad: In initial configuration for testing - the LM4F120 LaunchPad port. This is to support testing only and - is not yet a functional board port (as of 2013-03-01). - * arch/arm/include/lm/lm4f_irq.h and arch/arm/src/lm/chip/lm4f_vector.h: - Add interrupt vector/IRQ number definitions for the LM4F120. - * arch/arm/src/stm32f20xxx_dma.c and stm32f40xxx_dma.c: Fix a typo - in assigned base register addresses for each DMA channel. From - Yan T. - * Several build fixes from Mike Smith were incorporated. These were - mostly compilation errors introduced into the system because of the - large number of recent changes with broad scope (2013-03-04). - * configs/zkit-arm-17969/src/up_can.c: Add CAN support to the - Zilogics Technologies ZKIT-ARM-1769 board (From Rashid Fatah, (2013-03-04)). - * arch/arm/src/lpc17/lpc17*_clockconfig.c: The WaveShare Open1788 - board now boots and passes the OS test. This is the work of - Rommel Marcelo (2013-03-04). - * arch/arm/src/lm/lm_gpio.c, lm_gpio.h, and chip/lm4f_pinconfig.h - Extend GPIO logic to handle LM4F. Add LM4F pin configuration header - file (2013-03-04). - * configs/open1788: Enable LED support in all configurations. - (2013-03-04) - * configs/open1788/nsh: NSH configuration verified function. By Rommel - Marcelo (2013-03-05). - * configs/open1788/src/lpc17_nsh.c: Use the SD card interface, not SPI - to interface with SD cards (2013-03-05. - * arch/arm/src/lpc17xx/lpc17_sdcard.c and header files: Clone the STM32 - SD card interface to the LPC1788. It appears to be the same IP. - (2013-03-05) - * libc/wqueue: Work queue logic moved from sched/ to libc/wqueue. It - is not really core OS functionality and this move helps prepare for - user-space work queues. (2013-03-05) - * libc/wqueue: Implemented user-space work queues. These will not - get tested until the next time I attempt a NuttX kernel build. - (2013-03-05). - * arch/arm: Correct some bad syscall dispatching logic. This change - cannot be fully tested until there is a fielded NuttX kernel build. - (2013-03-06). - * net/net_poll.c: Correct logic that checks if the socket is - disconnected when the poll is setup. That is bad logic: Listen - sockets, for example, are not connected. In that case, the purpose of - the poll is to wait for connection events. As a result of this, - poll/select would return immediately with POLLHUP with it was used to - detect connection events. This fix for now was to check instead if - the socket is closed (meaning that it was connected at one time but - was closed by the remote peer). That excludes the listen socket which - was never connected. This does introduce a new problem, however. If - the socket was not closed, but lost the connection through an abnormal - event, then poll/select will hang. That needs to be revisited. - (2013-03-07) - * fs/fs_select.c: Was not checking if the timeout parameter was NULL - but would, instead, setup a bogus timeout based on whatever it found at - address zero. Also, improved some of the memory allocation logic so - that it will not use so much memory. (2013-03-07) - * net/net_poll.c: Handle the missing case. Now tests for not connected - AND not listening. I think that now covers all of the cases including - the missing case noted above. (2013-03-07) - * mm/: Move all memory manager globals into a structure. A reference - to this structure is now passed internally between mm APIs. This - change will (eventually) support multiple heaps and heap allocators. - (2013-03-08). - * mm/ and include/nuttx/mm.h: Implement support for multiple heaps. - (2013-03-08). - * arch/*/src: xyz_addregion() needs to call kmm_addregion, not mm_addregion. - (2013-03-08). - * sched/kmm*.c: Move this garbage kmm*.c file to mm/. until I decide what - to do with them (which is probably to just delete them). (2013-03-08). - * mm/mm_test.c and Makefile.test: Deleted the memory test. This was - a good test and helped me a lot when I wrote the memory manager, but - now it is in the way and paralyzing other efforts. So the memory unit - test was deleted. (2013-03-08) - * sched/sched_free.c: Rename sched_free() to sched_ufree(); Add - sched_kfree() to handler deferred kernel heap allocations. (2013-03-10) - * arch/: User user-accessible heap to allocate all stacks. (2013-03-10) - * arch/arm/src/sam3u: The AT91SAM3U will now support a kernel heap if - so configured. (2013-03-10) - * configs/sam3u-ek/knsh: This configuration was converted to use the - kconfigs-frontends build tool. (2013-03-10) - * configs/*/include/user_map.h and include/nuttx/userspace.h: Remove - the very kludgy user_map.h file and replace it with a header that - is expected at the beginning of the user-space blob. (2013-03-10) - * configs/sam3u-ek/kernel/up_userspace.c: This is the header for - the SAM3U-EK's user space. (2013-03-10) - * sched/os_bringup.c: In the kernel build, os_bringup() now uses the - user-space header to automatically start the user-space work queue, - if so configured. (2013-03-10) - * arch/arm/src/lpc17xx/lpc17_mpuinit.c and lpc17_userpace.c: Add - support for the MPU and kernel build for the LPC17xx family. - (2013-03-11) - * configs/open1788/kernel and knsh: Add kernel build support and - a kernel NSH configuration for the WaveShare Open1788 board. - (2013-03-11) - * configs/sam3u_ek/kernel, knsh, and scripts: Move some files around - for better supportability. (2013-03-11) - * configs/open1788/kernel, knsh, and scripts: Add a kernel mode build - configuration for the WaveShare Open1788 board. (2013-03-11) - * arch/arm/src/armv7-m/up_mpu.c: Several fixes to MPU logic. - (2013-03-12). - * arch/arm, configs/sam3u-ek, configs/open1788: Fix memory map for - kernel mode build; Some regions were overlapping. (2013-03-13). - * arch/: Rename g_heapbase to g_idle_topstack. This is the same value - however: The top of the IDLE stack is the same as the base of the - heap in the flat build. But not in the kernel build: The base of - the heap is elsewhere so the naming was wrong. (2013-03-13). - * libc/stdlib/lib_itoa.c: Implementation of itoa() contributed by - Ryan Sundberg. (2013-03-14). - -6.27 2013-04-28 Gregory Nutt - - * arch/arm/src/armv7-m/up_mpu.c: Correct MPU sub-region settings for - unaligned regions (2013-03-15). - * arch/arm/src/armv6-m/up_svcall.c: Bring up to equivalent to the - ARMv7-M version (2013-03-15). - * configs/lm4f120-launchpad/tools: Add scripts and instructions to - simplify use of OpenOCD with ICDI (from JP Carballo, 2013-03-15). - * tools/mkconfig.c: Logic that attempts to suppress buffered I/O - within the kernel is wrong. sizeof(struct file_struct) must be - the same in both kernel- and user-spaces (2013-03-16). - * arch/arm/src/common/up_pthread_start.c, libc/pthread/pthread_startup.c, - and related files: Implement switch to user-space and user-space - pthread start-up function (2013-03-16). - * arch/arm/src/common/up_signal_handler.c, libc/pthread/pthread_startup.c, - and related files: Implement switch to user-space and user-space - pthread start-up function (2013-03-16). - * arch/arm/src/common/up_signal_handler.c, libc/signal/signal_handler.c, - arch/arm/src/armv[6|7]-m/up_svcall.c, arch/arm/include/armv[6|7]-m/svcall.h, - include/nuttx/userspace.h, and sched/sig_deliver.c: Implement switch - to user-space from kernel signal delivery trampoline before calling user- - space signal handler. Return from user-space signal handler using a - system call (2013-03-16). - * arch/arm/src/armv[6|7]-m/up_schedulesigaction.c: Need make sure we are - in kernel mode before switching to kernel-mode signal handler - trampoline (2013-03-16). - * arch/arm/include/armv[6|7]-m/irq.h, and arch/arm/src/armv[6|7]-m/up_svcall.c: - Add support for nested system calls. In the current design, this can - happen only under one condition: When the kernel system call logic calls - back into user space in order to allocate user space memory. So it is - expected that the maximum nesting level will be only 2 (2013-03-17). - * libc/stdio/lib_sccanf.c: Correct an error in sscanf. If %n occurs in - the format statement after the input data stream has been fully - parsed, the %n format specifier will not be handled. Reported by - Lorenz Meier (and also earlier by Kate) (2013-03-17). - * drivers/serial/serial.c: Support for O_NONBLOCK was not supported - in the "upper half" serial driver. This is normally not an issue - because UART TX is almost always available, but it does become an - if the UART uses hardware flow control or if the a "lower half" is - something like the USB CDC/ACM driver that may need to block for - significant amounts of time (2013-03-18). - * arch/arm/src/armv7-h/ram_vectors.h, up_ramvec_*.c, arch/arm/src/*/*_irq.c, - and Make.defs: Add support for modifiable interrupt vectors in RAM - (2013-03-18). - * arch/arm/src/armv7-m/up_exception.S, sam3u/sam3u_vectors.S, and - lpc17xx/lpc17_vectors.S: In exception handling with CONFIG_NUTTX_KERNEL, - need to explicity set and clear the privilege bit in the CONTROL - register on return. I assumed this would be handled automatically - by the EXC_RETURN. Silly me (2013-03-18). - * arch/arm/src/lpc17_adc.c: Add a work-around for an ADC errata. From - Chris Taglia (2013-3-19). - * arch/arm/src/armv7-m/up_hardfault.c: If the PRIMASK is used to disable - interrupts, then additional logic is required in the hard fault handler - (2013-3-19). - * libc/ and mm/: Directories where the same sources files are used to - build different objects in the first and second pass kernel builds need - to keep those objects in separate directories so that they are not - constantly rebuilt (2013-3-19). - * fs/fat: Create an error in FAT file creation. The FAT logic was - not making a distinction between directory non-existence and file - non-existence so when it you try to create a file in a non-existent - directory, it would create a file with the name of the missing - directory. Reported by Andrew Tridgell (2013-03-30). - * Numerous files: Changed the protoypes of up_create_stack() and - up_release_stack() so that is includes a task type. Normally you - can get this type from the TCB parameter, but there are certain - conditions when the task type is not valid in the TCB when these - functions are called. Only the prototypes were changed on this - big, initial checkin. The next step will be to add logic to - allocate stacks for kernel threads from protected kernel memory - and all other task types from unprotected user memory (2013-03-20). - * arch/*/src/common/up_createstack.c, up_use_stack.c, and - up_release_stack.c: If creating or releasing the stack for a kernel - thread, use the kernel allocator so that the kernel thread stacks - are protected from user application meddling (2013-03-20). - * arch/arm/src/armv[6|7]-m/up_scall.c: Fix parameter passing for - all system call inline functions with > 3 parameters (2013-03-20) - * arch/*/src/common/up_stackframe.c and include/nuttx/arch.h: Add - and new interface to set aside memory on the stack. This will be - used at least in the kernel build to hold task arguments (2013-03-21). - * sched/sig_deliver.c: When dispatching signals to user threads, - copy the siginfo_t from the sigq to the stack. The signal queue - is allocated from kernel memory; however, the current stack is - the user's stack and the user code will be able to access the - signinfo_t data from the stack copy (2013-03-21). - * arch/arm/src/stm32: Added support for the kernel mode build - (cloned from the lpc17xx). (2013-03-21). - * configs/stme32f4discovery/kernel and scripts: Add support for - the kernel mode build on the STM32F4Discovery (2013-03-21). - * drivers/st7567.c/h and include/nuttx/lcd/st7567.h: Driver for - the ST7567 LCD Display Module from Univision Technology Inc. - contributed by Manikandan.S (2013-03-22). - * configs/zkit-arm-1769: Now supports the ST7567 LCD display - module. Added an nxhello configuration for testing (Manikandan.S, - 2013-03-22). - * configs/stm32f4discovery/kostest: Add a kernel mode version - of the OS test for the STM32F4Discovery board (2013-03-22). - * nuttx/include/nuttx, nuttx/configs/sam3u-ek, nuttx/configs/open1788, - nuttx/configs/stm32f4discovery, and nuttx/arch/arm: Complete - re-archtecting of how signals are dispatched to user-space code - in the kernel build. The original implementation was C-based - and simpler. However, the C code intermixed with SVC calls was - not properly preserving registers. The more complex, assembly - language version does not suffer from these issues. I believe - the kernel build can now be called "feature complete" - (2013-03-23). - * binfmt/binfmt_execmodule.c: Here is a place where I forget - to update the call to sched_releasetcb() to pass the thread - type as the second parameter (2013-03-23). - * arch/arm/src/lm, kinetis, lpc43, and nuc1xx: Add kernel build - support to all ARMv7-M and ARMv6-M chips. There are no - configurations in place to verify these additions! - (2013-03-24). - * arch/arm/src/lm/lm_gpio.h: Correct typos in alternate function - definitions (2013-03-24). - * arch/arm/src/lm/lm_lowputc.c and lm_serial.c: Add support for - the 7 UARTs on the LM4F120 (2013-03-24). - * configs/lm4f120-launchpad/ostest/defconfig: Fix the configured - RAM size.

The SDRAM is basically functional, but there are - failures with the SDRAM is stressed by the memory test at - apps/example/ramtest (SDRAM support and the RAM test can be configured - into the base configs/open1788/nsh configuration as described in - configs/open1788/READMT.txt (2013-3-27). - * configs/open1788/nxlines: Add a configuration to test both the - Open1788 LCD and SDRAM which is used as a framebuffer (2013-3-27). - * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: Began - implementation of the LPC17 DMA and integration into the SDCARD - driver (2013-3-29). - * arch/arm/src/lpc17xx/lpc17_gdma.c: LPC17 DMA is code complete and - under test. Does not yet work (2013-3-30). - * fs/fat/fs_fat32dirent.c and fs_fat32util.c: Several fixes to the - FAT file system from Ronen Vainish. These fixes mostly involve the - logic to extend directory clusters for the case of long file names - but also include a few important general fixes (such as for storing - 32 bit FAT values) (2013-03-31). - * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: SD card DMA - is now functional. Thre may be some issues with DMA from CPU SRAM - which is apparently disabled in sleep mode; up_idle() always enters - sleep mode (2013-03-31). - * arch/arm/src/stm32: Add architecure support for the STM32 F427/F437 - chips. Contributed by Mike Smith (2013-4-01). - * configs/zkit-arm-1769/src/up_can.c: Add support for both CAN1 - and CAN2.

But this raises a problem when the - MCU has multiple blocks for differ SPI implementations as does the - LPC17xx (and also as does other architectures like STM32 that have - USARTs that can serve as SPI interfaces as well). These were renamed - to lpc17_spiinitialize() and lpc17_sspinitialize() in this case. - Problem reported by M. Kannan (2013-4-01). - * arch/arm/src/lpc17xx/lpc17_gpdma.c and lpc17_idle.c: In sleep mode, - DMA can only be performed from peripheral SRAM. CPU SRAM is shutdown - in sleep mode. In order to simplify DMA memory allocation, the LPC17xx - IDLE will now hold off going to sleep mode if there is a DMA in progress - (2013-4-01). - * configs/open1788/src/lpc17_autoleds.c: Reversed sense of the IDLE LCD. - It is now off when the LPC17 is sleeping and on when awake.

So remove the second extension - $(NUTTX)$(EXEEXT) in two places (2013-4-7). - * arch/arm/src/lpc17xx/lpc17_gpioint.c: Disable interrupts in - lpc17_setintedge(). This logic must be atomic because it can be - re-entered before it completes enabled interrupts, sometimes - leaving the interrupts in a strange state (2013-4-7). - * arch/arm/src/lpc17_lcd.c: Rommel Marcelo got the LPC1788 - framebuffer-based LCD working. Very nice! (2013-4-08). - * arch/arm/src/lm/lm_clockconfig.c and configs/lm4f120-launchpad: - Fix handling of the RCC SYSDIV2 field when the PLL output is - 400MHz.

Basically instead of one - driver structure with an arrayof root hub port structures, there is no - one container structure with an array of driver structures, one for - each root hub port. The advantage is that each class->driver call not - passes information associated with the RHport implicitly. The klugey, - procedural alternative was to add the function address to every - interface method (which I started to do but backed above) (2013-8-13). - * arch/arm/src/sama5/sam_memories.c and .h: Extended logic so do - conversions from physical to virtual addresses (2013-8-14). - * arch/arm/src/sama5/sam_ohci.c: Add D cache contols and conversion - between physical and virtual address (2013-8-14). - * arch/arm/src/stm32/stm32_spi.c: nbits() interface extended to - control bit order as well as bit width (from Teemu Pirinen) - (2013-8-16) - * arch/arm/src/sama5/sam_ohci.c: More to be tested, but the SAMA5 - OHCI driver is now basically funtional (2013-8-16). - * include/nuttx/usb/ehci.h: EHCI header file (2013-8-17). - * arch/arm/src/stm32/stm32_i2c.c: Correct an error that crept into - the STM32 F1 I2C driver with some recent changes.

This - method is intended to get various information about the connected device, - but currently returns only the device speed. The device speed is - necessary by usbhost_enumerate in order to set a credible initial EP0 - max packetsize. High speed needs 64 bytes, low speed needs 8 bytes, - and full speed can handle almost any size (2013-8-26). - * arch/arm: Add hooks for Cortex-A8.

This - one differs from sst25.c because it supports larger SST25 parts: In - the larger parts support page write instead of byte/word writes like - the smaller parts. From Ken Pettit (2013-11-28). - * drivers/mtd/smart.c: Fixes a minor bug with SMART partition number - reporting (that would only be seen if both partition support and - multi-root directory support are enabled at the same time).

From Ken - Pettit (2013-11-28). - * fs/fs_inode.c: The inode semaphore must be re-entrant. Here is the - re-entering path that I found: (1) USB host connects to FLASH drive - and creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is - removed but /dev/sda is not destroyed because there is still a - reference on the device because of the mount, (4) umount() is called, - taking the inode semaphore, now the driver tries to destroy the block - driver by calling unregister_blockdriver(). But (5) - unregister_blockdriver() also takes the inode semaphore causing a - deadlock if the inode semaphore is not re-entrant.

NAND can report read errors because of bad ECC. Logic - in NXFFS must account for it and not just throw in the towel every - time a read fails (2013-11-30). - * drivers/mtd/mtd_nand* and arch/arm/src/sama5/sam_nand.c: NAND - accesses now work (at least with software ECC and now DMA). Still - lots of testing to be done (2013-11-30). - * fs/nxffs/nxffs_dump.c: Do not abort on a read error. Just not - the error and continue. Otherwise, we would not be able to dump - NAND FLASH (2013-11-30). - * fs/nxffs: All read error logic has been revisited and modified in - most places. If we are using NAND, then read errors probably mean - that the block that was read contains uncorrectable bit errors. In - this case, we cannot just give up and abort the operations. Rather, - we need to treat read error like normal bad blocks in order to work - with NAND (2013-12-2). - * fs/nxffs/Kconfig and nxffs_initialize.c: Make the start up scan of - the media option. It just takes to long! (2013-12-02). - * drivers/mtd/mtd_nand.c: Fix a typo in calculation of page number - (2013-12-02). - * drivers/mtd/README.txt: New README file (2013-12-04). - * arch/arm/src/lm/lm_start.c: Don't initialize .data if not running - from FLASH (2013-12-05). - * fs/fat/fs_configfat.c: Fix a typo in the FAT16 formatting logic. - Was this ever able to format a FAT16 volume? (2013-12-05). - * drivers/mtd/mtd_nand.c: Check if block number is within range at - the top of the loop not the bottom. Otherwise, we will do a bogus - transfer with the out-of-range block before we test it (2013-12-05). - -6.33 2014-01-30 Gregory Nutt - - * arch/arm/include/a1x and src/a1x: Directory structure to support - the Allwinner A10.

Also, we - don't need different scripts for the CMNVECTOR case now that the vector - table has a common name. - * arch/arm/src: armv-7/up_exception.S and xxx/xxx_vectors.S where - xxx={kinetis, lm, lpc17xx, sam34, and stm32}: Modified register usage - when saving the context on the stack: In order to handler nested - interrupts, the stack pointer must be used so that when it is - decremented, the contents on the stack are protected from the nested - interrupt handling (2013-12-23). - * arch/Kconfig: The CONFIG_ARCH_INT_DISABLEALL feature is disabled (i.e., - depends on EXPERIMENTAL). That is because the current implementation - will not work because interrupts get disabled in the interrupt handler - too, defeating the nesting of interrupts. The fix is easy: It just - needs more levels of priority of disabling interrupts vs interrupt - handling (2013-12-23). - * configs/viewtool-stm32f107/src/stm32_highpri.c: Improved debug output - (2013-12-23). - * drivers/lcd/memlcd.c and include/nuttx/lcd/memlcd.h: Support for the - Sharp Memory LCD from Librae (2013-12-23). - * configs/maple/nx and src/: Add support for a custom Sharp Memory - LCD on the Maple board.

Noted by Brian Webb (2013-12-27). - * graphics/nxmu, nxsu, and nxglib and libc/nx, nxmu, and nxglib: Massive - reshuffling of files with (hopefully) no logic changes. This - reshuffling is necessary if we ever want to build graphics applications - as kernel builds. There is still more today (NXTK and NXFONTS need to - be moved to libc as well) (2013-12-27). - * Move libc/nx, nxmu, and nxglib to a new library, libnx.

Additional typo in nx_constructwindow.c - (wnd should be hwnd). Also noted by Steve Redler IV (2014-1-7). - * configs/viewtool-stm32f107/src/stm32_touchscreen.c (and other - files): Add support for the XPT2046 touchscreen controller on - the Viewtool LCD module connected to the Viewtool STM32F103 - board (2014-1-9). - * libc/strings/lib_stpcpy.c: Add stpcpy() (2014-1-9). - * arch/arm/src/a1x/a1x_lowputc.c and a1x_serial.c: Mystery - finally solved: The A10 serial clock is the OSC24M clock. - Thanks to Alan Carvalho de Assis (2014-1-10) - * binfmt/binfmt_loadmodule.c: Fix a memory leak (2013-1-11). - * configs/stm3vldiscovery: Support for the STM32VL-Discovery board. - Contributed by Alan Carvalho de Assis (2014-1-12). - * net/net_close.c, net/Kconfig, include/nuttx/net/net.h, and - include/sys/socket.h: Add support for the SO_LINGER socket option. - Extended from logic provided by Jason Jiang. Enabled with - CONFIG_NET_SOLINGER. At this point, it has only been verified that - the changes does not seem to do any harm (2014-1-13). - * net/connect.c and net/uip/uip_callback.c: prevent tcp_connect - callback from being double freed. From Max Holtzberg (2014-1-13). - * net/Kconfig and include/nuttx/net/uip/uipopt.h: Add configuration - support for forthcoming TCP write buffering (2014-1-13). - * net/net_send_buffered.c, net_send_unbuffered.c, and - uip/uip_tcpwrbuffer.c: First set of changes to bring in Jason - Jiang's TCP write buffering logic. Still not complete but - apparently harmless if not selected. (2014-1-13). - * All of Jason Jiang's TCP write buffering logic is checked in. - Unfortunately, it does not yet work (2013-1-14). - * configs/px4fmu-v2_upstream: Configuration for testing simple - configurations on the PX4FMU v2. This version is incomplete - for the PX4 application and is not a replacement for the version - in the PX4 GIT repository. - * fs/fat/fs_fat32.c: A correction to FAT cluster allocation from - Tridge via Lorenz Meier (2014-1-14). - * net/net_clone.c: If CONFIG_NET_TCP_WRITE_BUFFERS is selected, - then the socket-related write buffering information must copied - with the other cloned socket data (2014-1-14). - * net/net_close.c: If CONFIG_NET_TCP_WRITE_BUFFERS is selected, - then it is necessary to free the write buffer callback structure - when the socket is closed (2014-1-14). - * fs/fat/fs_fat32.c: Fix some root directory logic that was - conditionally done only for FAT 32. Apparently this needs to - done for all FAT types. From Tridge via Lorenz Meier - (2014-1-14). - * arch/arm/src/armv6-m/up_doirq.c and armv7-m/up_doirq.c and all - implementations of up_maskack_irq() for all Cortex-M architectures: Do - not disable and enable the IRQ on each interrupt. Because (1) - interrupts are already disabled on interrupt entry, (2) this - interferes with controlling the IRQ interrupt setting from interrupt - handlers, and (3) up_disable_irq() does not work anyway so that this - has never done anything (2014-1-15). - * All implementations of up_disable_irq() for all Cortex-M3 and M4 - architectures: To enable an interrupt on the Cortex-M3/4 CPU, you - need to set a bit in the ISER registet on the Cortex-M3/4 CPU, you - need to set a bit in the ISER register. To disable the interrupt, you - need to set a bit in the ICER register. Existing logic was trying to - disable interrupts by clearing the bit in the ISER register. That will - not work; writing a '0' to the ISER register has no effect. That - means that up_disable_irq() was doing nothing! It turns out that that - is not really important because up_disable_irq() is not really used - for that purpose. But some spurious STM32 ADC interrupts have been - reported to me and this turned out to be the cause in that case. My - concern now that up_disable_irq() works is that there may now be - unmasked bugs that leave devices in the disabled state? Thanks to - Manuel Sthn for the tip(2014-1-15). - * libc: Move strtol(), strtoll, strtoul(), strtoull(), and strtod() from - libc/string to libc/stdlib where they belong (2014-1-16). - * configs/Kconfig: Board configuration sub-directory can now be - specified. The default need not be used. This is really only - useful when CONFIG_ARCH_BOARD_CUSTOM is selected and there is no - meaningful default sub-directory (2014-1-16). - * configs/Kconfig: Backed out the previous change for two reasons: - (1) it has a bad side effect in that the sub-directory setting - no longer tracks the board setting, and (2) you still can't - source the Kconfig file from the custom board directory (2014-1-16). - * Makefile.unix, Makefile.win, and configs/Kconfig: After thinking a - little harder, I re-implemented the backed-out custom configuration - feature. The new version does not have bad side-effect (1) (but still - has bad side-effect (2)) (2014-1-16). - * arch/x86/Kconfig and configs/qemu-i486/nsh/Make.defs and - ostest/Make.defs: Add a configuration option to select the -m32 - compiler option when building for a 32-bit target on a native 64-bit - compiler (2014-1-18). - * include/ctype.h: Typo in macro name: iscntrl, not iscontrol (2104-1-17) - * libc/unistd/lib_getopt.c: If there are no arguments (argc == 1), then - getopt() will leave the optind variable in an undefined state (2014-1-20). - * configs/olimex-stm32-p107: Fails to build if SPI3 for UEXT is not - remapped. From Max Holtzberg (2014-1-21). - * Several network related files: Changes from Max Holtzberg to improve - how network status is reported. New controls to manage carrier - detect. (2014-1-21). - * configs/16z: Add basic support for the 16z board. The 16z board is - based on the ZiLOG ZNEOZ16F2811AL20EG part. See - https://github.com/toyaga/16z for further information (2014-1-22), - * tools/Config.mk: 'cypath' must be called if we are using a Windows - native toolchain with the Cygwin 'make' to convert paths to proper - Windows paths.

From Richard Cochran (2014-1-23). - * arch/arm/src/efm32 and include/efm32: Basic support for the EFM3 - processor family from Richard Cochran (2014-1-23). - * configs/efm32-dk3650: This is Energy Micro's development kit for - the Leopard Gecko MCU, which is an ARM Cortex-M3 device. From Richard - Cochran (2014-1-23). - * arch/arm/src/armv7-m/up_memcpy.S: Assembler changes with the gcc-47 - distribution from ARM mean that we need to be explicit about branch - sizes; one or more of the wide branch opcodes results in bad table - branching. From Mike Smith (2014-1-23). - * Many files: renamed up_buttoninit() to board_button_initialize to - better conform to the naming standard. Now ONLY prototypes in - include/nuttx/arch.h (2014-1024). - * Rename up_buttons() to board_buttons() for the same reason (2014- - 1-14). - * Rename up_irqbutton() to board_button_irq() (2014-1-24). - * Rename up_ledinit() to board_led_initialize() (2014-1-24). - * Rename up_ledon() to board_led_on() and up_ledoff() to board_led_off() - (2014-1-24). - * arch/x86/src/qemu-i486/gemu_head.S: Patch from Matt Campbell - to fix 'Error: .size expression for idle_stack does not evaluate to - a constant" (2014-1-25). - * arch/arm/include/efm32, arch/arm/src/efm32, and configs/efm32-dk360: - Removed all EFM32 support. Not yet ready to be fielded (2014-1-27). - * arch/arm/src/armv7-a/arm_head.S, sama5/sam_boot.c, and several other - files: Now supports execution from NOR FLASH with .data and .bss in - SDRAM. This was not possible prior to this because .bss and .data - were initialized before SDRAM was configured. This logic is still - kind buggy. (2014-1-28). - * arch/arm/src/armv7-a/arm_head.S and arm_pghead.S: Back off to a - somewhat less efficient loop for initializing .data and .bss. The - original, efficient logic violated the ARM C ABI. It was okay when - called from boot logic, but not when called from C logic. This fixes - bugginess reported on 2014-1-28. (2014-1-29). - -7.1 2014-03-15 Gregory Nutt - - * arch/arm/src/lm/lm_serial.c: Fix cut'n'paste error that prevented - UARTS2-7 from being used with the LM4F120 Launchpad (2014-02-03). - * configs/stm32f4discovery/src: Almost everything renamed to conform - to the ever-evolving naming standard (2014-02-03). - * arch/arm/src/a1x/a1x_serial.c: Had the same cut'n'paste error - that the LM4f120 Launchpad had (2013-02-03). - * Documentation/NuttXCCodingStandard.html: Add a coding standards - document.

But there are usability issues: How do you use the - mouse with no cursor? The HID mouse currently emulates a touchscreen - driver. That would work in the long run for several reasons (see the - top-level TODO list for details) (2014-2-9). - * include/nuttx/input/mouse.h and drivers/usbhost/usbhost_hidmouse.c: - Defined a mouse interface that is very similar to a touchscreen - interface, but allows reporting of all mouse buttons. Also, unlike - touchscreen drivers, mouse drivers need to report positional data - with no button is pressed so that the mouse position can drive a - cursor (2014-2-10). - * drivers/usbhost/usbhost_hidmouse.c, include/nuttx/input/mouse.h, and - include/nuttx/usb/hid.h: Add support for a mouse wheel (2014-2-10). - * drivers/lcd/mio283qt9a.c and include/nuttx/lcd/mio283qt9a.h: Support - for the MIO283QT9A LCD.

It was using - pthreads before and these were changed to a kernel thread. The reason - for this has to do with task grouping: A pthread is a memory of the - group of the task that started it. A kernel thread is independent of - the task that started in (other than knowing it as the parent).

Critical bugfix: From time to - time (after some hours) the Ethernet receiver would lose one receive - interrupt and the IP stack never recover because there is no receive - watchdog as the transmit watchdog. From Max (2013-7-24). - * audio/pcm_decode.c: Add missing audio callback forwarding logic - (2014-7-25). - * arch/arm/armv7-a/l2cc_pl310.h: Move arch/arm/sama5/chip/sam_l2cc.h to - arch/arm/armv7-a/l2cc_pl310.h. Adjust the two corresponding Kconfig - files as well (2014-7-25). - * arch/arm/src/armv7-a/arm_l2cc_pl310.c, l2cc.h, l2cc_pl310.h, Kconfig: - Add initial support for the ARM L2CC-PL310 L2 cache (2014-7-26). - * arch/arm/src/armv7-a/cp15_cacheops.h: Rename ARMv7-A cache.h to - cp15_cache.h. Things will be broken on this commit until I get the - new cache.h in place (2014-7-26). - * arch/arm/src/armv7-a/cache.h: New cache.h file. Renames all functions - like cp15_XYZ_cache() to arch_XYZ_cache() and adds L2 cache support if - L2 cache is enabled (2014-7-26). - * arch/arm/src/sama5/*.c (many files): Change naming from cp_XYZ_cache() - to arch_XYP_cache() so that all cache operations will pick up L2 - support if it is enabled (2014-7-26). - * arch/arm/src/sama5/sam_boot.c: Enables cache early in boot-up sequence - (2014-7-26). - * arch/arm/src/armv7-a/arm_l2cc_pl310.c and l2cc.h: Minor bugfixes/ - improvements (2014-7-26) - * arch/arm/src/armv7-a/Kconfig: L2 Cache currently depends on - EXPERIMENTAL because it does not yet work properly (2014-7-26). - * include/nuttx/audio/audio.h: Move sub-sampling rate definitions from - nxplayer.h to audio.h (2014-7-17). - * audio/pcm_decode.c: PCM: First cut at fast forward by sub-sampling. - This design is overkill: It manages too many audio buffers. I think - that a cleaner design could do all sub-sampling in place without - managing additional audio buffers (2014-7-27). - * drivers/audio/audio_null.c: Was not returning buffers to the upper - level (2014-7-27) - * include/nuttx/audio/audio.h and audio/pcm_decode.c: Misc bugfixes - while integrating fast forward by sub-sampling (2014-7-27). - * audio/pcm_decode.c: Back out a change; the fix really belongs in - NxPlayer. (2014-7-27). - * arch/arm/src/lpc17xx/lpc17_adc.c and arch/arm/src/lpc17xx/lpc17_ethernet.c: - ADC updates from Max. Also fixes some syntax errors that I introduced in - the last commit (2014-7-28). - * audio/pcm_decode.c: Fix a logic error in a DEBUG assertion (2014-7-28). - * configs/sama5d4-ek/src/sam_pmic.c, dram_main.c, sama5d4-ek.h, Makefile. - Add logic to disable the faulty PMIC. This must be done with JP23 open. - It is performed only from the DRAMBOOT loader (2014-7-28). - * drivers/audio/wm8904.c: Fix some compile problems with the WM8904 driver - due to recent audio subsystem changes (2014-7-28). - * arch/arm/src/sama5/sam_timerisr.c and configs/sama5d3*/include/board*.h: - Correct system timer frequency. Input clock is MCK/2, not MCK - (2014-7-29). - * fs/fs_automount.c and include/nuttx/fs/automount.h (plus hooks in other - files): Add support for an auto-mounter that will automatically mount - and unmount a file system a media is inserted and removed (2014-7-29 . - * configs/sama5d4-ek/src/sam_automount.c: Add automounter support for - HSMCI0 and HSMCI1 (2014-7-29). - * configs/sama5d4-ek/Kconfig and src/sam_hsmci.c: Minor warning/latent - bug clean-up of auto-mounter logic (2014-7-29). - * configs/sama5d4-ek/README.txt anand src/sam_nsh.c, fs/fs_automount.c, - and include/nuttx/fs/automount.h: Cosmetic updates to comments and - README files and some naming (2014-7-29). - * configs/sama5d4-ek/nsh/defconfig and nxwm/defconfig: The SAMA5D4-EK - NSH and NxWM configurations now have the auto-mounter configured to - automatically mount the FAT file system on HSMCI0 at /mnt/sdcard - (2014-7-29). - * arch/arm/src/sama5/sam_hsmci.c: Add method to do RX transfer without - DMA. The 8-byte SCR transfer was failing silently with the DMA - transfer, leaving the SD card in single bit mode (2014-7-29). - * arch/arm/src/sama5/sam_hsmci.c: Fix a problem on card insertion/removal - callback handling. Interrupts were being disable so that the callbacks - occurred with interrupts disabled. This resulted in loss of some - interrupts and some not-so-good behaviors. The solution is to perform - all callbacks on the work thread unconditionally (2014-7-30). - * nuttx/fs/fs_automount.c: Auto-mounter: Fix state setting. Not - harmful other than it can cause a debug assertion to fire if you - manually unmount the media before removing it which is, of course, - what you are supposed to do (2014-7-30). - * arch/arm/src/sama5/sam_hsmci.c and README files: Re-enable TX DMA and - verify that DMA writes to the SD card are functional. They are so now - TX DMA is re-enabled in the driver. This might affect the SAMA5D3 - platforms where the TX DMA problem was found. The SAMA4D3 and 4 use - the same HSMCI driver. Much has change since then and it is not - surprising that DMA is now functional. However, the has not be re- - verified on the SAMA5D3 which has a different DMA controller - (2014-7-30). - * arch/arm/src/sama5/sam_dmac.c, sam_pio.c, and sam_pioirq.c: Changes - needed for a clean SAMA5D3 build after all of the recent SAMA5D4 - changes (2014-7-31). - * configs/sama5d3x-ek/nsh/defconfig: Refresh configuration (2014-7-31). - * configs/sama5d3x-ek/Kconfig, README.txt, src/sam_wm8904.c, Makefile, - sam_nsh.c, and sama5d3x-ek.h: Add support for the WM8904 audio CODEC - (2014-7-31). - * configs/sama5d3x-ek/nxplayer: Add a configuration to support the - command line NxPlayer (2014-7-31). - * audio/audio.c: More debug output (2014-7-31). - * configs/sama5d3x-ek/README.txt: REAME update (2014-7-31). - * drivers/audio/wm8904.c: Was not saving I2S interface instance - (2014-7-31). - * sched/sem_wait.c: Use set_errno() and get_errno(). Direct access - inside the OS may not be supported in the future (2014-7-31). - * drivers/audio/audio_null.c, vs1053.c, wm8904.c, include/nuttx/audio/audio.h, - libc/audio/lib_buffer.c: Change how the end of the audio stream is - detected by the leaf audio component. This used to be done by looking - for the first partial buffer. That does not work with the in-place - sub-sampling performed by the PCM decoder: That always reduces the - size of the buffer so that all buffers only partially filled by the - time they get to the leaf. Now, a flag is set in the audio buffer - flags set to indicate the final buffer in the stream (2014-7-31). - * arch/arm/src/sama5/sam_ssc.c: Needs to account for data offset in - audio buffer (2014-7-31). - * drivers/audio/wm8904.c: Can't reset the WM8904 unless we also - reinitialize all registers. Try to get a saner timeout based on - sample rate, bits-per-sample, and buffer size (2014-7-31). - * arch/arm/src/sama5/Kconfig and sam_ssc.c: SCC Frame Synch Delay and - Start Delay are now configurable (2014-8-1). - * drivers/audio/wm8904_debug.c: Add logic to dump WM8904 registers - (2014-8-1). - * drivers/audio/wm8904.c: Fix an error in write logic. I am not sure - why this fixes the problem (2014-8-1). - * include/nuttx/audio/wm8904.h (and implementers of the interface): - the WM8904 driver needs to know the frequency of the MCLK in order - to set up the FLL to generate the correct bitrate (2014-8-1). - * WM8904: Add an option to control WM8904 register dumping (2014-8-2). - * WM8904: Add logic to program the FLL to achieve the bitrate - (2014-8-1). - * arch/arm/src/sama5/sam_ssc.c: Verify that the requested bit width - is supported. Correct some alignment tests that depend upon the data - bit width (2014-8-2). - * audio/pcm_decode.c: Correct the end of audio stream handling. It was - not being detected before so that logic was not examining the WAV - header in the first buffer of the next audio file (2014-8-2). - * configs/sama5d3x-ek/nxplayer/defconfig: Update with last WM8904 - settings (2014-8-2). - * drivers/audio/wm8904.c: Disable the FFL at the end of playing - (2014-8-2). - * include/nuttx/audio/wm8904.h: Fix wm8904_dump_registers macro: - Wrong number of parameters (2014-8-2). - * arch/arm/src/sama5/sam_pck.* and all SAMA5D board header files: - Add Main clock as an option for the PCK clock source (2014-8-3). - * configs/sama5d*-ek/Kconfig and src/sam_wm8904.c: Add option to - use MAINCK as source fort he WM8904 MCLK (2015-8-3). - * include/nuttx/audio/wm8904.h, configs/sama5d3x-ek/src/sam_wm8904.cm, - and sama5d4-ek/src/sam_wm8904.c: WM8904 interface enable method now - returns the previous interrupt state (2014-8-4). - * configs/sama5d3x-ek/src/sama5d3x-ek.h and sama5d4-ek/src/sama5d4-ek.h: - Correct the WM8904 interrupt configuration, active high level. Fix - that and don't pull-up (2014-8-4). - * configs/sama5d3x-ek/src/sam_wm8904.cm, and sama5d4-ek/src/sam_wm8904.c: - Correct ordering of some WM8904initialization: Need to provide MCLK - before initializing the WM8904, not after (2014-8-4). - * drivers/audio/wm8904.c and .h: Correct calculation of bitrate (I am - not sure why this is correct). LR clock divisor is now a constant 32- - bits per frame. Conditioned out interrupt logic; it is not being used. - Also added some FLL lock interrupt/poll logic (which was subsequently - disabled) (2014-8-4). - * SAMA5D3x-EK and SAMA4D4-EK: Add/update usage documents for media - players (2014-8-4). - * drivers/audio/wm8904.c and .h: Add reset logic to put the part back - in its initial state after playing each WAV file. Base samples per - second on frame length, not bits-per-sample. Use a different frame - length for 8-bit and 16-bit data (2014-8-4). - * arch/arm/src/sama5/sam_hsmci.c: TX DMA is again disabled for the - SAMA5D3 family. Although it works with the SAMA5D4 (which has a - different DMA subsystem), it does not work with the SAMA5D3 (2014-8-5, - see also 2014-7-30). - * audio/pcm_decode.c: Handle errors in the PCM WAV file in a way that - the Nxplayer can recover gracefully: Send and Audio Complete message - (2014-8-5). - * arch/*/src/*/*_timerisr.c, up_initialize.c, and up_internal.h: Re-name - up_timerinit() to up_timer_initialize() for compatibility with new - tickless OS interface name (2014-8-6). - * arch/*/src/*/Make.def: Don't build existing timer initialization - logic if CONFIG_SCHED_TICKLESS is defined (2014-8-6). - * include/nuttx/arch.h: First cut at platform-specific interfaces - needed to support tickless OS option (2014-8-6). - * sched/Kconfig: Add a new option CONFIG_SCHED_TICKLESS to enable the - tickless OS. This is a work in progress but should be relatively - safe since the new features are only enabled by this option (Safer - but not 100% safe since it does not protect from typos and other - dumb errors) (2014-8-6). - * arch/sim/src/Makefile, up_idle.c, up_internal.h, and up_tickless.c: - Add support for a simulated interval timer support verification of - the tickless OS (2014-8-6). - * include/nuttx/arch.h: Added another tickless OS interface to get - the timer remaining on the interval timer (2014-8-6). - * include/nuttx/clock.h, sched/clock_initialize.c and clock_internal.h: - If CONFIG_SCHED_TICKLESS is defined, then the global variable - g_system_timer does not exist (2014-8-6). - * sched/Makefile: Don't build in sched_processtimer.c if - CONFIG_SCHED_TICKLESS is selected (2014-8-6). - * sched/clock_gettime.c and clock_settime.c: Use the clock_systimer() - macro, do access the g_system_timer() global directly (2014-8-6). - * sched/clock_systimer.c: Uses interval timer interfaces to get the - time if CONFIG_SCHED_TICKLESS is selected (2014-8-6). - * sched/sched_timerexpiration.c, Makefile, os_internal.h, - sched_addreadytorun.c, sched_processtimer.c, sched_unlock.c, - wd_cancel.c, wd_internal.h, and wd_start.c: Implements the - tickless OS (2014-8-7). - * Many files: Remove CONFIG_DISABLE_CLOCK. Why? This option is not - really very useful and was only selected in a few unusable, mostly - unusable configurations anyway (m9s12/ostest, kl25z/minnsh, - z180/ostest, 8051, sh1, z80, and z8). The only real loss is probably - to the kl25z/minsh configuration . And with the addition of the - tickless OS, I just wanted to make the pain go away (2014-8-7). - * Many files: Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. - This gives more options for system timers in general, but more - importantly, let's us realize higher resolution for the case of - CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new - integer overflow problems 2014-8-7). - * Many files: Change all time conversions. Yech. New timer units - in microseconds breaks all existing logic that used milliseconds - in the conversions. Something likely got broken doing this, - probably because I confused a MSEC2TICK conversion with a TICK2MSEC - conversion (2014-8-7). - * arch/sim/src/up_tickless.c and sched/sched_timerexpiration.c: The - tickless OS now appears fully functional and passes the OS test - on the simulator with no errors (2014-8-7). - * sched/mqueue: Move POSIX message queue files from sched/ to - sched/mqueue (2014-8-8). - * sched/signal: Move signal-related files from sched/ to sched/signal - (2014-8-8). - * sched/pthread: Move all pthread files from sched/ to sched/pthread - (2014-8-8). - * sched/semaphore: Move POSIX counting semaphore files from sched/ to - sched/semaphore (2014-8-8). - * sched/environ: Move environment files from sched/ to sched/environ - (2014-8-8). - * sched/group: Move group logic from sched/ to sched/group (2014-8-8). - * sched/wdog: Move watchdog functions from sched/ to sched/wdog - (2014-8-8). - * sched/irq: Move interrupt dispatch logic from sched/ to sched/irq - (2014-8-8). - * sched/clock: Move clock functions from sched/ to sched/clock - (2014-8-8). - * sched/timer: Move POSIX timer files from sched/ to sched/timer - (2014-8-8). - * sched/paging: Move page fill sources from sched/ to sched/paging - (2014-8-8). - * sched/init: Move initialization functions from sched/ to sched/init - (2014-8-8). - * sched/errno: Move errno related files from sched/ to sched/errno - (2014-8-8). - * sched/task: Move task control files from sched/ to sched/task - (2014-8-8). - * sched/: Move a few files in sched/ that did not seem to have a home to - sched/signal and sched/task (2014-8-8). - * sched/sched: Move scheduler files from sched/ to sched/sched - (2014-8-8). - * (Many files): Replace os_internal.h with sched/sched.h in files that - actually reference something in sched.h (2014-8-8). - * sched/task/exit.c: Move sched/exit.c to sched/task/exit.c (2014-8-8). - * (Many files): Remove os_internal.h it has been replace by several new - header files under sched/. There have been some sneak inclusion paths - via os_internal.h, so expect a few compilation errors for some - architectures (2014-8-8). - * Documentation/NuttxPortingGuide.html, arch/sim/src/up_tickless.c, and - include/nuttx/arch.h: Fix errors in documentation and comments related - to the Tickless OS. From Vijay Kumar (2014-9-9). - * arch/arm/src/sama5/sam_tc.c and .h: Can now handle non-constant - BOARD_MCK_FREQUENCY. Also now supports methods to attach user - interrupt handlers (2014-8-9). - * drivers/audio/audio_null.c: Fix an error in a variable name - (2014-8-9). - * arch/arm/src/sama5/sam_oneshot.c, .h, Kconfig, Make.defs, sam_tc.c, - .h, and sam_adc.c: Add support for a one-shot timer wrapper around - the low-level timer/counter logic. This also involved several changes - that rippled into the ADC driver (untested) (2014-8-9). - * arch/arm/src/sama5/sam_freerun.c, .h, Kconfig, and Make.defs: Add - support for a free-running timer wrapper around the low-level - timer/counter logic (2014-8-9). - * arch/arm/Kconfig, src/sama5/sam_tickless.c, Kconfig, Make.defs: Use - the one-shot and free-running timers to implement tickless OS support - for SAMA5 (2014-8-9). - * arch/arm/src/sama5/sam_oneshot.c and sam_tc.c: Fix several bugs in - timer/counter interrupt logic and one-shot timer logic. Comments and - debug output updated in additional files (2014-8-10). - * sched/wdog/wd_start.c: Correct a bug in Tickless OS support: logic to - detect changes in head of timer list was wrong (2014-5-10). - * sched/sched/sched_timerexperation.c, sched.h, and wdog/wd_start.c: In - tickless mode, need to stop the interval timer before inserted a new - delay into the timer list. Otherwise, the time is incorrect on the - first entry of the list (2014-8-11). - * arch/arm/src/sama5/sam_freerun.c and sam_oneshot.c: Correct bad time - conversion, 1000000 not 1000 to convert seconds to microseconds - (2014-8-11). - * sched/sched/sched_timerexpiration.c: Fix inaccurate time conversion. - Remove MSEC_PER_TICK from calculation and convert uint32_t to uin64_t - (2014-8-11). - * libc/time/lib_localtime.c, private.h, tzfile.h and several header and - make-related files: Adds support for localtime. From Max Neklyudov - (2014-8-12) - -7.5 2014-09-28 Gregory Nutt - - * clock/clock_systimespec.c and sched/clock/clock_gettime.c: When - reading the system timer, don't read a struct timespec, convert it - to a fake tick count, then back to a timespec (2014-8-15). - * sched/clock/Make.defs, clock_gettime.c, clock_settime.c, include/time.h, - nuttx/clock.h, configs/vsn/src/sif.c: Remove CLOCK_ACTIVETIME. It is non- - standard, unused, and gets in the way of maintaining clocks (2014-8-15). - * libc/time/lib_localtime.c: Modified to that the coding style is much - closer to NuttX coding style. The local header files private.h and - tzfile.h were removed and incorporated into lib_localtime.c. All - conditional compilation within lib_localtime.c that unconditionally - evaluated to FALSE was removed (2014-8-15). - * drivers/net/Kconfig and include/nuttx/arch.h: Standardize a PHY - interrupt attachment interface (2014-8-16). - * configs/Kconfig, sama5d3-xplained, sama5d3x-ek, and sama5d4-ek: - Convert existing board specific PHY interrupt interfaces to use newly - defined standard interface (2014-8-16). - * include/net/slip.h: Move SLIP prototypes from net.h to slip.h - (2014-8-16). - * include/net/net.h and net/: Fix some missing function headers - (2014-8-16). - * drivers/net/phy_notify.c, include/nuttxarch.h, net/phy.h, and - ioctl.h: Add support for an ioctl that can be used to notify an - application when there is a change in the network status signalled - by a PHY interrupt (2014-8-16). - * drivers/net/phy_notify.c, include/net/if.h, ioctl.h, netdev.h, phy.h, - and net/netdev/netdev_ioctl.c: Finishes the ioctl definition to - subscribe to PHY events. Revamp network ioctl signature to support - arguments other than struct mii_ioctl_data (2014-8-16). - * arch/arm/src/stm32/stm32_eth.c: Modified to support the change to the - network ioctl signature changes.

That guess is often wrong. A better approach would be to - call strtol() directly on the input data, using the endptr return - value to determine how many characters to skip after parsing. From - Kosma Moczek (2014-8-18). - * net/arp/arp_dump.c: Add missing configuration option to select - dumping of ARP packet headers. Move ARP dumping logic from - arp_inout.c to its own file (2014-8-18). - * net/arp/arp_out.c: Move arp_out() from arp_inout.c to its own file - (2014-8-18). - * net/arp/arp_arpin.c: Move arp_arpin() from arp_inout.c to its own file - (2014-8-18). - * net/arp/arp_ipin.c: Rename arp_inout.c to arpipin.c because that is - all that is left in the file (2014-8-18). - * net/arp/arp_format.c: Move the logic that formats an ARP packet into a - separate file where it can be re-used. (2014-8-18). - * net/arp/arp_out.c and net/pkt/pkt_send.c: Change how the IFF_NOARP - flag is handled. This should be set only when data is moved into the - buffer and cleared after tested by the ARP logic. Setting it globally - can cause packets to be sent with no valid MAC addresses (2014-8-18). - * net/arp/arp_send.c: Partial implementation of logic to send ARP - requests to assure that an IP address mapping is present in the ARP - table (2014-8-18). - * net/arp/arp_poll.c: Finished the implementation of logic to send ARP - requests. Complete, fully hooked into the networking logic, and ready - for test (but still untested) (2014-8-18). - * net/icmp/icmp_ping.c, net/socket/net_sendfile.c, sendto.c, - net/tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c: If - CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send - operations will call arp_send() before attempting the real send - operation. arp_send() will check if the IP address mapping is in - the ARP table and, if not send ARP requests periodically until it is. - This eliminates losing the first outgoing message because there is not - mapping in the ARP table (2014-8-18). - * net/arp/arp_notify.c, arp_send.c, arp_arpin.c, and arp.h: Add - signalling logic so that we do not have to wait so long with the - network responses to ARP requests quickly (2014-8-19). - * include/nuttx/lcd/ili9341.h: Add a register definition header file - for the ILI9341 LCD (2014-8-19). - * net/arp/Kconfig: ARP request logic is no longer EXPERIMENTAL - (2014-8-20). - * net/arp/arp_send.c: ARP request logic needs to do the right thing if - (1) the address is a broadcast or multicast address, and (2) if the - IP address lies outside of the network. Problem noted by Manuel Stuehn - (2014-8-20). - * configs/sam4e-ek/src/Kconfig and src/sam_ili9341.c: Add ILI9341-based - LCD driver. Fully functional (2014-8-20). - * configs/sam4e-ek/nxwm: Add an NxWM configuration for the SAM4E-EK - (2014-8-21). - * configs/viewtool-stm32f107: Refresh some configurations (2014-8-20). - * nuttx/sched/wdog: If we run out of pre-allocated watchdog times, the - logic will allocate additional timers from the heap. A reserve of - pre-allocated watchdog timers is maintained so that there will always - be timers available for interrupt handlers (2014-8-21). - * include/nuttx/wdog.h (and many affected files): wdog.h does not - contain any application interface, only internal OS interface. - Further, it is non-standard.

NuttX processes are now functional - on the Cortex-A (2014-9-11). - * arch/arm/src/armv7-a/arm_fullcontextrestore.S, arm_syscall.c, crt0.c, - and svcall.h: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. - It changed CPSR while in kernel. That will crash if the new CPSR is - user mode while executing in kernel space. Fixed by adding a - SYS_context_restore system call. There is an alternative, simpler - modification to up_fullcontextrestore() that could have been done: It - might have been possible to use the SPSR instead of the CPRSR and then - do an exception return from up_fullcontextrestore(). That would be - more efficient, but I never tried it (2014-9-12). - * binfmt/libelf/libelf_load.c: ELF: Critical bugfix..

This is - problematic, because the interrupt handler calls can_txdone of the - upper half which can enqueue new packets to send. Removed the block - altogether, because can_txdone calls can_xmit which disables - interrupts if there are no new packets to send. From Daniel Lazlo - Sitzer (2014-9-17). - * drivers/can.c: In can_txdone, waiters on the semaphore should be - informed regardless of the return value of can_xmit.

Use this value to replace some - logic committed yesterday (2014-11-15). - * configs/stm32f4discovery/netnsh/defconfig: Needs to set MAC address - (2014-11-15). - * arch/ and drivers/: Remove use of NET_LL_HDRLEN from Ethernet drivers. - Use ETH_HDRLEN instead (2014-11-15). - * net/arp/: Remove use of NET_LL_HDRLEN from net/arp logic. Use - ETH_HDRLEN instead (2014-11-15). - * net/ and include/nuttx/net: All network logic will now handle - variable length link layer protocol headers within incoming packets. - This permits use of multiple network interfaces with differing data - links. For example, ETHERNET + SLIP (2014-11-15). - * arch/arm/src/sam34/sam4s_periphclks.h: Add missing SPI0 clock - configuration macro for the SAM4S. From spasbyspas (2014-11-16). - * arch/arm/src/efm32/efm32_lowputc.c: EFM32 USART setup: Computation of - BAUD includes shift; Eliminate additional shift. From Pierre-noel - Bouteville (2014-11-16). - * net/, include/, drivers/, arch/, various files: Rename - CONFIG_NET_BUFSIZE to CONFIG_NET_ETH_MTU; Add CONFIG_NET_SLIP_MTU. - Add data structures and logic to handle different MTUs when both - Ethernet and SLIP are enabled (2014-11-16). - * net/, include/, various files: Rename CONFIG_NET_RECEIVE_WINDOW to - CONFIG_NET_ETH_TCP_RECVWNDO and CONFIG_NET_SLIP_TCP_RECVWNDO. Add - data structures and logic to handler different TCP receive windows - when both Ethernet and SLIP are enabled (2014-11-16). - * configs/sama5d4-ek/bridge: Add a simple test for the dual EMACs on - the SAMA5D4 (2014-11-17). - * arch/arm/src/sama5/sam_emacb.c: Fix several typos that will prevent - EMAC1 from initializing properly (2014-11-17). - * include/nuttx/net/ip.h and tcp.h, net/icmp/icmp_send.c and - igmp/igmp_send.c: Move IP header flags from tcp.h to ip.h and rename - IP_FLAGS vs TCPFLAGS. The problem fixed here is that there IP flags - were not available when TCP was disabled. The IP flags are used in - ICMP and IGMP (2014-11-17). - * sched/clock/clock_abstime2ticks.c: Calling mq_timedreceived() with - immediate timeout was getting stuck and not timing out. Immediate - timeout is achieved by setting absolute timeout value to past time, - for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute - time was converted to relative time using unsigned integer arithmetic - and resulted large ticks count by clock_abstime2ticks, instead of - expected negative ticks value. Change corrects clock_abstime2ticks() - to return negative ticks, if absolute time is in the past. From - Jussi Kivilinna (2014-11-19). - * fs/vfs/fs_poll.c: poll() was not waking up from signals (for example - mq_notify() events). From Jussi Kivilinna (2014-11-19). - * arch/arm/src/stm32/stm32_otghs.c, Make.defs, - configs/stm32f429i-disco/src/stm32_usb.c and Makefile: STM32 F4 OTGHS - device controller driver from Brennan Ashton (2014-11-20). - * configs/sama5d3-xplained/bridge: Add a simple test for the EMAC - and GMAC on the SAMA5D3 working together (2014-11-20). - * libnx/nxtk/nxtk_drawframe.c: Remove warnings when CONFIG_NXTK_BORDERWIDTH - is set to zero. From Pierre-Noel Bouteville (2014-11-20). - * fs/vfs/fs_poll.c: Add proper handling for sem_timedwait errnos. - From Jussi Kivilinna (2014-11-21). - * net/udp/udp_conn.c and udp.h: Extensions to UDP "connection" structure - for the case of multiple networks. In this case, assigned port numbers - only have to be unique with respect to the IP address. So, for - example, you could have multiple port 80's, one on each network - (2014-11-21). - * net/tcp/tcp_conn.c and tcp.h: Make tcp_listener static scope; it is - not used outside of tcp_conn.c (2014-11-22). - * net/udp/tcp_conn.c and tcp.h: Extensions to TCP connection structure - for the case of multiple networks. See the description of the similar - change for UDP above (2014-11-22). - * net/route/net_router.c: Refuse to perform routing table lookups for - the Broadcast IP address. From Brennan Ashton. - * net/netdev/netdev_findbyaddr.c and netdev: Add logic to netdev_findbyaddr() - to return the correct network device for the case where a broadcast - address is used. This change caused trivial ripples through other - files because additional parameters are required for netdev_findbyaddr() - when CONFIG_NET_MULTINIC. Those other file include net/netdev/netdev_rxnotify.c, - netdev_txnotify.c which, in turn, for changes to arp/arp_send.c, - icmp/icmp_ping.c, socket/net_sendfile.c, recvfrom.c, sendto.c, - tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c (2014-11-23). - * arch/arm/src/kl/chip/kl_i2c.h: I2C header file for the Freescale KL - family.

From - Alan Carvalho de Assis (2014-11-23). - -7.7 2015-01-26 Gregory Nutt - - * nuttx/drivers/eeprom and include/nuttx/eeprom/: Add support for generic - EEPROM access via a character driver. Add also the EEPROM driver itself. - From Sébastien Lorquet (2014-11-26). - * libnx/nxfonts/nxfonts_pixel-lcd-machine.h and nxfonts_pixel-unicode.h, - include/nuttx/nx/nxfonts.h, graphpics/Kconfig, and build-related files - in libnx/nxfonts: Two new fonts from Pierre-noel Bouteville (2014-11-26). - * configs/lpc4357-evb, arch/arm/src/pc43xx/chip/, configs/Kconfig, and - and other related files: A port of NuttX to the LPC4357-EVB from - Toby Duckworth. This port is a leverage of the LPC3330-Xplorer port - and still have a some misinformation from that port that needs to be - updated for the LPC4357-EVB (2014-11-26). - * arch/arm/include/stm32/chip.h, src/stm32/Kconfig, chip.h, and - chip/stm32f102_pinmap.h: Enable support for the STM32 F102. From - https://github.com/PX4/NuttX/pull/28.diff (2014-11-27). - * drivers/loop.c: Loop device should return -EINTR is interrupt by a - signal (2014-11-27). - * drivers/input/djoystick.c and include/nuttx/input/djoystick.h. Also - drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add - an interface definition and upper half driver for a discrete joystick - device (2014-11-27). - * arch/arm/src/efm32/Kconfig and efm32_serial.c: Add support for serial - termios TCGET and TCSET. For the moment, only set/get speed is - implemented. From Pierre-noel Bouteville (2014-11-27). - * drivers/wireless/ and include/nuttx/wireless/cc3000.h: A set of 11 - patches correcting issues with the CC3000 networking. All from Jussi - Kivilinna (2014-11-28). Among these: - 03/11: CC3000 driver was getting stuck at recv() when remote host - closed connection and application tried to read data from remotely - shutdown socket. This patch adds proper handling for remotely closed - socket event. - 07/11: Socket state initialization was done in 'register', while it - should be initialized in 'open' and deinitialized in 'close'. Old - way caused problems when device is closed, power-cycled and then - reopened as old socket state was left enabled. - 08/11: Select thread was getting stuck after 'close, power-cycle, - reopen', since selectsem was not properly setup and cleaned up. - 09/11: 'maxFD' was not properly reset in select worker and not checked - for before calling cc3000_select(). - 10/11: After wlan_stop()/cc3000_close(), irqsem was left with count - '-1'. Therefore on next wlan_start()/cc3000_open(), initial value - for irqsem was wrong. Additional repeated wlan_start()/wlan_stop() - decreased irqsem value further. Obviously this causes driver not to - function correctly and freeze. Patch moves initialization and - destruction of waitsem, irqsem and readysem to - cc3000_open/cc3000_close. - * include/cxx/cctype: Undefine macros defined ctype.h so that builtin - C++ implementations will be used intead. From Lorenz Meier - (2014-11-28). - * configs/stm3210e-eval/src/stm32_djoystick.c: Add a discrete Joystick - supportfor the STM3210E-EVAL (2014-11-28). - * drivers/input/djoystick.c include/nuttx/input/djoystick.h: Add a new - ioctl to get the supported joystick discrete signals (2014-11-28). - * drivers/input/ajoystick.c and include/nuttx/input/ajoystick.h. Also - drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add - an interface definition and upper half driver for an analog joystick - device. Initial check-in is only a little more of a clone of the - discrete joystick driver and is as-of-yet untested (2014-11-27). - * libc/Kconfig, misc/Make.defs, misc/lib_ioctl.c, fs/vfs/fs_ioctl.c, - include/nuttx/fs/fs.h, include/sys/ioctl.h, syscall.h, and several - files in syscall/: Add support for a variadic ioctl() function. The - ioctl() interface is a non-standard, Unix interface. NuttX has always - used the older, three-parameter version. Most contemporary systems - now, however, use a variadic form of the ioctl() function. Added an - option to insert a shim layer to adapt the three-parameter ioctl() to - use the variadic interface form. Internally, the ioctl handling is - the same three-parameter logic. The only real complexity to the shim - is in how the system calls must be handled (2014-11-29). - * arch/arm/src/stm32/stm32_i2c.c: Port Tridge's I2C noise resilience - logic from the PX4 repository (2014-11-29). - * arch/arm/src/stm32/chip/stm32l15xxx_pinmap.h: Fix a typo in the - MCO pin definition.

From Sebastien - Lorquet (2014-12-5). - * sched/mqueue: msg type should be char * not void * in mq_send, - mq_timedsend, mq_receive, and mq_timedreceive. Noted by Pierre-Noel - Bouteville (2014-12-05). - * fs/mqueue/mq_open.c and sched/mqueue/mq_msgqalloc.c: In message queue - creation return ENOSPC error if size exceeds the configured size of - pre-allocated messages; Use ENOSPC vs ENOMEM per OpenGroup.org. From - Pierre-Noel Bouteville (2014-12-6). - * Add sys/custom_file.h. Used when CUSTOM_FILE_IO is define and avoids - re-definition errors about the FILE define.

Discovered and fixed by Sebastien Lorquet after much - consternation (2014-12-8). - * libc/stdio/lib_avsprintf.c: avsprintf(): Fix a bug in usage of - va_list on x86. On x86, va_list is a pointer to a single copy on the - stack. avsprintf() calls lib_vsprintf() twice and so traverses the - va_list twice using va_start. va_start modifies that single copy on - the stack so that the second call to lib_vsprintf() fails. This appears - to be an issue with x86 only so far (2014-12-8). - * stdint.h: Don't use hex values to specify minimum values of fixed - width, signed values. Hex values are inherently unsigned and not - usable for this purpose in all contexts (2014-12-8). - * arch/arm/src/tiva/tiva_i2c.c, tiva_i2c.h, Kconfig, and Make.defs: Add - build framework and skeleton files for Tiva I2C driver.

From Sébastien Lorquet (2014-12-12). - * libc/stdio/lib_sscanf.c: Also accept %F as well as %f (2014-12-12). - * arch/arm/src/stm32/stm32_otghsdev.c: For STM32 OTG HS DEV (in FS - mode): Disable ULPI clock enable in RCC AHB1 Register. If Both ULPI - and the FS clock enable bits are set in FS mode, then the ARM never - awakens from WFI due to a chip issue. This is only an issue if you - are using the internal PHY. From Ken Pettit (2014-12-13). - * drivers/serial/serial.c: In case a thread is doing a blocking - operation (e.g. read()) on a serial device, while it is being - terminated by pthread_cancel(), then uart_close() gets called, but - the semaphore (dev->recv.sem in the above example) is still blocked. - This means that once the serial device is opened next time, data will - arrive on the serial port (and driver interrupts handled as normal), - but the received characters never arrive in the reader thread. - The problem was fixed by re-initializing the semaphores on the last - uart_close() on the device. From Harald Welte (2014-12-13). - * sched/semaphore/sem_recover.c, Make.defs, seamphore.c, - sched/wdog/wd_recover.c, Make.defs, wdog.h, sched/task/task_recover.c: - Add logic to clean up after task_delete() or pthread_cancel() if the - task happens to be waiting on a semaphore when it is cancelled - (2014-12-13). - * arch/arm/src/kl/kl_gpioirq.c, Kconfig, Make.defs, and kl_irq.c: Add - GPIO interrupt capability for the KL architecture. The patch is - almost the same as kinetis_pinirq.c, just minor modifications and - rename kl_pinirq to kl_gpioirq to make it more generic to developers. - From Alan Carvalho de Assis (2014-12-13). - * arch/sim/src/up_ajoystick.c, Kconfig, Makefile, up_idle.c, - up_internal.h, up_x11eventloop.c, up_x11framebuffer.c, - configs/sim/src/Makefile, sim_boot.c, and traveler/defconfig: Add an - X11 mouse-based simulation of an analog joystick device (2014-12-14). - * drivers/sensors/adxl345*, include/nuttx/sensors/adxl345.h and other - files: Add driver support for the ADXL345 accelerometer. From Alan - Carvalho de Assis (2014-12-16). - * configs/freedom-kl25z: Add board support for the ADXL345 accelerometer. - From Alan Carvalho de Assis (2014-12-16). - * Kconfig, include/debug.h, drivers/sensors/*, and Qencoder logic in - arch/arm/src/stm32 and various QEncoder board support files under - config/: Unify sensor debug. ADX driver was using input debug; LM75 - and QENCODE that their own custom debug. Now all use - CONFIG_DEBUG_SENSOR, sndbg() (2014-12-16). - * configs/dk-tm4c129x: Initial board support for the Tiva DK-TM4C129x - Connected Development Kit. The initial commit is just the Tiva - TM4C123G-Launchpad board support with naming changes (2014-12-16). - * include/nuttx/sched.h, sched/Kconfig, sched/init/os_start.c, - sched/pthread/pthread_create.c, sched/task/task_prctl.c, - sched/task/task_setup.c: strncpy() will not copy the terminating \0 - into the destination if the source is larger than the size of the - destination. Ensure that the last byte is always zero and let strncpy - only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names - can be observed in ps when creating a pthread while - CONFIG_TASK_NAME_SIZE is set to 8. From Daniel Willmann (2014-12-17). - * configs/*/*/defconfig: The previous change increased the task name - size allocation by one to hold a NUL terminator. This changes reduces - the configured name size by one so that no additional memory is used - (2014-12-17). - * drivers/wireless/cc3000/cc3000.c: CC3000 Fix: Data can be unaligned. - When dereferenced as an input ntosh(), a bad value is returned. - Reported by Alan Carvalho de Assis (2014-12-18). - * configs/freedom-kl25z: Update the Freedom KL25Z board CC3000 support - to use the current CC300 interfaces.

Initial commit is - basically just the STM32 Ethernet driver with modifications for a clean - compilation in the Tiva environment (2014-12-31). - * arch/arm/src/stm32/stm32_rtc.c, stm32_rcc.c, Kconfig: Add support for - the internal low speed clock (LSI) as a source of the RTC clock. Some - boards do not have the external 32khz oscillator installed, for those - boards we must fallback to the crummy internal RC clock. Turn on by - defining CONFIG_RTC_LSICLOCK. From Kevin Hester (2015-01-02). - * net/tcp/tcp_conn.c: Fix a logic error when CONFIG_NETDEV_MULTINIC is - selected: net_unlock(flags) will be called will an uninitialized - variable (2015-01-03). - * arch/arm/src/tiva/tiva_irq.c: Fix Tiva IRQ control logic; was limited - to only 64 IRQs. That is a problem for higher numbered IRQs on many - platforms (2015-01-06). - * arch/arm/src/stm32/stm32_sdio.c, drivers/mmcsd/mmcsd_sdio.c and Kconfig, - and include/nuttx/sdio.h: MMCSD SDIO: Add support for a new - SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop - to poll the card R1 status to determine when the card was ready for - the next transfer. That busy-wait can be quite long -- up to hundreds - of milliseconds. An alternative is to look the SD D0 pin which - will change state when the card is no longer busy. This change avoids - the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, - then waiting for the card to become ready without taking up CPU - cycles. This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE - and is currently only implemented for the STM32 SDIO driver. From - David Sidrane (2015-01-08). - * arch/arm/src/tiva/tiva_timerlib.c and .h: Add a timer library for - generic support of Tiva timers (2015-01-08). - * arch/arm/src/tiva/tiva_timerlow32.c: Add a driver lower half for - drivers/timer.c. Only 32-bit periodic timers are supported. This - provides userspace access to timers. - * configs/px4-v2_upstream, Kconfig, README.txt: Remove the px4-v2_upstream - configuration. Moved to misc/Obsoleted/configs. This was not the - official configuration for the PX4 board and has led to confusion by - NuttX users. The board configuration also requires some ongoing - maintenance and customization to support ongoing PX4 testing and - evaluation. It is best retained the PX4 repositories where it can be - properly maintained and not in the upstream NuttX repository - (2015-01-14). - * net/netdev/netdev_ioctl.c and include/nuttx/net/ioctl.h: Add support - for IPv6 ioctls to manipulate IP addresses (2015-01-14). - * net/icmpv6: Create a future home for ICMPv6 (2015-01-14). - * net/icmp: Remove all logic conditioned on CONFIG_NET_IPv6 - (2015-01-14). - * net/, include/nuttx/net, and a few other files: (1) Copied all ICMP - sources files to net/icmpv6 with proper renaming and removal of IPv4 - logic, (2) remove IPv6 logic from files in net/icmp, (3) copied - include/nuttx/icmp.h to icmpv6.h and removed IPv4 specific logic, (4) - removed all IPv6 logic from icmp.h, (5) IP_HDRLEN became IPv4_HDRLEN - and IPv6_HDRLEN, (6) ip_chksum() became ipv4_chksum() and - ipv6_chksum(), and (7) added partial support for ICMPv6 statistics - (2015-01-14). - * arch/, drivers/net/, include/nuttx/net, and net/devif: (1) Rename - devif_input() ipv4_input(), (2) copy net/devif/devif_input.c to - ipv6_input.c, remove all IPv4-specific logic, (3) rename - net/devif/devif_input.c to ipv4_input.c, remove all IPv6-specific - logic, and (4) xplit IPv4 header structure out as net_ipv4hdr_s from - net_iphdr_s (2015-01-15). - * arch/ and drivers/net: All Ethernet drivers: Call ipv6_input() if - IPv6 is enabled and an IPv6 packet is received (2015-01-15). - * net/devif, net/tcp, net/ucp, include/nuttx/net: Separate tcp_input() - and udp_input() into separate functions tcp_ipv4_input(), - tcp_ipv6_input(), udp_ipv4_input(), and upd_ipv6_input() than can deal - will the data offsets caused by the differing sizes of the IP header - (2015-01-15). - * net/utils/net_ipv6_maskcmp.c: Add missing implementation of - net_ipv6_maskcmp() (2015-01-15). - * Networking: Drivers can have both IPv4 and IPv6 addresses, but a - socket can only only one or the other; The socket connection - structures need to include a union of IPv4 and IPv6 addresses for - the local address binding and for the remote address connections - (2015-01-16). - * Networking: Replace all references to net_ipaddr_t with either - in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and - IPv6 simultaneously. This requires that the two types be distinct - and not conditionally typedef'ed to net_ipaddr_t (2015-01-16). - * Networking: Replace all references to the macros net_ipaddr_copy, - net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and - net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the - macro (such as net_ipv4addr_copy). The goal is to support both - IPv4 and IPv6 simultaneously. This requires that the macros be - distinct and not conditionally defined to one on or the other - (2015-01-16). - * Networking: UDP and TCP MSS depends on the IP header size (as well - as the link layer header size) and cannot be represented with a - single value (2015-01-16). - * net/neighbor: Move net/ipv6 to net/neighbor (2015-01-16). - * include/net/if.h: Add a bit to the device flags to indicate if the - device packet buffer holds an IPv4 or an IPv6 domain packet. - Set/clear the flag along with the correct offset to the application - payload data as each packet is received (2015-01-17). - * net/socket, net/tcp, net/udp: Add logic to select the domain of the - outgoing packet before sending any UDP or TCP packet. This sets the - bit to indicate the IPv4 or IPv6 domain and the correct offset to the - output going payload data (2015-01-17). - * net/socket and net/tcp: When we are ready to receive data or when we - have outgoing data ready to be sent, we need to the notify the - appropriate device driver of this condition. The notifying socket - will be configured as either PF_INET or PF_INET6 and must look up the - correct driver using the correct IP domain (2015-01-17). - * net/socket/accept.c: Fix accept() so that it returns the correct IP - address for the selected socket IP domain (2015-01-17). - * Networking: Final detangling off IPv4 and IPv6 TCP/UDP send logic. - The networking subsystem now compiles with IPv6 enabled (2015-01-18). - * arch/arm/src/tiva/tm4c_ethernet.c: When calling into the stack - from the worker thread, it is necessary to have the stack locked - (2015-01-18). - * nuttx/arch/arm/src/stm32/stm32_serial.c: Fix declaration and - definition of up_receive() and up_dma_receive() to match fields of - uart_ops_s from nuttx/include/nuttx/serial/serial.h.

From Pavel Krienko (2015-01-19). - * net/icmpv6/icmpv6_solicit.c, net/neighbor/neighbor_out.c, and other - files: Add logic to search the Neighbor Table and update the - destination address in the output Ethernet header OR to send an - ICMPv6 Neighbor Solicitation if there is no entry in the Neighbor - table for the IPv6 address (2015-01-20). - * arch/ and drivers/net: Add missing raw/packet socket support to - all Ethernet driverss (2015-01-20). - * arch/ and drivers/net: Networking: Modify all Ethernet drivers: - Do neighbor look-up on all outgoing IPv6 packs in order to properly - set the destination link layer address (2015-01-20). - * Networking: When sending ICMPv6 advertisements and solicitations, - set the NOARP bit so that we don't overwrite the destination MAC - address (2015-01-20). - * Many files: Correct name of fields in struct sockaddr_in6: sin6_port - and sin6_family, not sin_port and sin_family (2015-01-20). - * net/socket/accept.c: Correct the value returned by accept() in the - case where net_lockingwait() is called. It was returning -1 and - losing the errno value. Noted by Rony Xln (2015-01-22). - * net/: After some significant effort, ICMPv6 and TCP are both - functional when IPv6 is selected. UDP still requires testing - (2015-01-22). - * configs/dk-tm4c129x/ipv6: Add an IPv6-enabled NSH configuration - (2015-01-23) - * include/nuttx/net/icmpv6.h and net/icmpv6/icmpv6_ping.c: First cut - at ICMPv6 ping logic. It works in both directions! (2015-01-23). - * arch/arm/src/efm32/efm32_rmu.c and .h: Add support for the EFM32 - reset management unit (RMU). From Pierre-noel Bouteville - (2015-01-23). - * include/nuttx/math.h: Adds support for the expm1 functions: - http://pubs.opengroup.org/onlinepubs/009695399/functions/expm1.html. - From Brennan Ashton (2015-01-23). - * Many file: Add CONFIG_STACK_COLORATION that does the same thing as - CONFIG_DEBUG_STACK but without enabling debug. From David Sidrane - (2015-01-24). - * Remove CONFIG_DEBUG_STACK. Adding CONFIG_STACK_COLORATION makes - this configuration option pointless (2015-01-24). - * net/: Clean up network status collection for IPv6 (2015-01-24). - * arch/ and configs/: Changes to get USART 2 & 3 working on - lpc4357-evb. These changes are required to get USART 2 and 3 working - on the Embest development board. From Toby Duckworth. - -7.8 2015-02-11 Gregory Nutt - - * include/nuttx/math.h and libc/math: Add support for inverse - hyperbolic functions. From Brennan Ashton (2015-01-26). - * include/nuttx/math.h: Add math library definition for isfinite(). - From Brennan Ashton (2015-01-26). - * include/nuttx/math.h and libc/math/lib_erf*.c: Add error function - to math library. From Brennan Ashton (2015-01-26). - * include/nuttx/math.h and libc/math: Add math library defines for - nan(), copysign(), and trunc() functions. From Brennan Ashton - (2015-01-26). - * sched/wqueue/kwork_process and libc/wqueue/lib_usrthread.c: Fix - a backward calculation when determining the time to the next event. - This is a bug in the back-up, "fail safe", work queue timing so it - not as bad as it seems. From Liio Chen via the PX4 repository - (2015-01-27). - * arch/arm/src/stm32/stm32_exti_gpio.c: Disabling any of EXTI 5-9 - interrupts was disabling interrupts for all EXTI 5-9. Same issue with - EXTI 10-15. From Jussi Kivilinna (2015-01-27). - * arch/arm/src/stm32/stm32_rtcc.c and Kconfig: Recent changes to - stm32_rtcc.c do not compile with STM32L15XX configurations. From - Jussi Kivilinna (2015-01-27). - * net/local: Add initial support for local, Unix domain sockets. - Initial support is limited to SOCK_STREAM and is untested on - initial commit (2014-01-27). - * net/iob, net/tcp/tcp_callback.c, and include/nuttx/net/iob.h: There - were issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS was - enabled: There is a possibility of deadlocks in certain timing conditions. - I have not seen this with the Tiva driver that I have been users but - other people claim to see the issue on other platforms. Certainly it - is a logic error: The network should never wait for TCP read-ahead - buffering space to be available. It should drop the packets - immediately. This was fixed by duplicating most of the IOB interfaces: - The versions that waited are still present (like iob_alloc()), but now - there are non-waiting versions of the same interfaces (like - iob_tryalloc()). The TCP read-ahead logic now uses only these non- - waiting interfaces (2015-01-27). - * net/tcp/tcp_send_buffered.c and tcp_wrbuffer.c: Fix another deadlock - condition. tcp_write_buffer_alloc() calls sem_wait() with network - locked. That worked if CONFIG_NET_NOINTS was not defined because - interrupts are automatically restored when the wait happens. But - with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- - bad style and also can lead to a deadlock condition (2015-01-28). - * arch/arm/src/armv7-a/arm_memcpy.S and arch/arm/src/armv7-m/up_memcpy.S: - ARM assembly language memcpy.S's were not returning a value in R0 they - are required to do. From David Sidrane (2015-01-29). - * net/local: Extend Unix domain socket support to include support - for datagram Unix domain sockets (2015-01-29). - * net/socket/accept.c: Fix a major TCP bug introduced with commit - e71c09ce9777ff732cb60bd07fb43d85522f79d6. Some connection logic was - reordered; setting the socket as 'connected' got moved to BEFORE the point - where the check was made if the socket was already connected. The - resulting behavior was odd: Telnet would connect, but then when you - exit and reconnect, it would fail to connect. But then if try again, it - would connect okay. So the symptom was connect-fail-connect-fail-... - (2015-01-29). - * net/socket/net_poll.c, recvfrom.c, and udp/udp_callback.c: Add UDP - read-ahead support. This enables support for for poll/select on UDP - sockets and also non-blocking UDP sockets. From Macs N (2015-01-30). - * net/local/local_netpoll.c, socket/net_poll.c, and udp/udp_netpoll.c: - Separate out UDP poll logic from net_poll.c into a new udp_netpoll.c; - Create a skeleton local_netpoll (2015-01-30). - * net/socket/net_poll.c and tcp/tcp_netpoll.c: Separate TCP poll logic - out of net_poll.c and move it into the new tcp_netpoll.c (2015-01-30). - * arch/arm/src/efm32/efm32_clockconfig.c: Logic to unconditionally enable - LE clocking. Even you don't use core clock LE as source for LFA or LFB, - to read are write any register not clocked by HFPERCLK or HFCORECLK, - HFCORECLKLE should be enabled. From Pierre-noel Bouteville (2015-01-30). - * drivers/net/slip.c: SLIP interface improvements. From Macs N - (2015-01-30). - * clock_systimespec(): Fixes for compilation errors in certain - configurations. From Macs N. - * drivers/pipes/fifo.c, include/nuttx/fs/ioctl.h, and net/local/local_fifo.c: - Fix a race condition between FIFO buffer operations and the opening and - closing of FIFOs which necessary when the FIFOs are used to support - Unix domain, datagram sockets. The default policy is the deallocate - FIFO buffering when the last client closes the pipe. When when used - for datagram communications, packets left in the FIFO will be lost. - Some like UDP read-ahead is needed: The buffered data in the FIFO - needs to be retained until the reader gets a chance to re-open the - FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. - Default (0) is the legacy behavior; Unix domain datagram logic sets - the alternative policy so that the packet data persists after the FIFO - is closed (2015-01-30). - * net/local: Add configuration options so that Unix domain stream and - datagram support can be separately enabled (2015-01-31). - * fs/vfs/fs_unlink.c and include/nuttx/fs/fs.h: Add an unlink method to - both the character and block driver interface. This is important - because if the driver inode is unlinked and there are no open references - to the driver, then the driver resources will be stranded. On the unlink - call, the driver has the opportunity (1) check if there an any open - references, and if not, (2) free the driver resources (2015-01-31). - * drivers/pipes: Implement the unlink method. If the pipe/FIFO is - unlinked, it will marked the pipe/FIFO as unlinked. If/when all open - references to the driver are closed, all of the driver resources will - be freed (2015-01-31). - * arch/avr: Added architecture support for the Atmel AVR ATMega1284P - MCU. From Jedi Tek'Unum (2015-01-31). - * configs/moteino-mega: Added support for the LowPowerLab MoteinoMEGA - that is based on the Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum - (2015-01-31). - * EFM32 RTC: RTC driver using BURTC. From Pierre-Noel Bouteville - (2015-02-01). - * drivers/ramdisk.c, include/nuttx/fs/ramdisk.h, and other files: Add - logic to dispose of the driver and RAM buffer when the RAM disk has - been unlinked and all open references to the RAM disk have been - closed. Add new parameters to romdisk() to specify what should be - done with the RAM/ROM buffer -- Should it be freed or not? Changed - all calls to ramdisk() to use these new parameters (2015-02-01). - * net/icmpv6/icmpv6_neighbor.c, icmpv6_notify.c (and other files): Adds - basic logic to support verification that we have the IPv6 address in - the Neighbor Table. This feature is important because otherwise the - first packet sent to a remote peer will fail (it will be replaced - with a Neighbor Solicitation) (2015-01-02). - * net/arp/arp.h, arp_notify.c, and arp_send.c: Fixes another - CONFIG_NET_NOINTS issues. When called sem_timedwait() with the - network locked, the network stays locked while we wait which is not - what we want (without CONFIG_NET_NOINTS, interrupts are re-enabled - while we wait and all is well) (2015-02-02). - * net/icmpv6/icmpv6.h, icmpv6_neighbor.c, icmpv6_notify.c: Apply the - same fix as for ARP to the Neighbor Solicitation logic (2015-02-02). - * sched/sched/sched_timerexpiration.c, Kconfig, and include/nuttx/arch.h: - On my platform I have just 16-bit timer clocked at 32kHz. As result - oneshot timer max delay is 2s. The patch adds limit of maximum ticks - in sched_timer_start(). From Macs N (2015-02-03). - * arch/arm/src/sam34: Add support for Tickless mode of operation for - the SAM4CM platform. From Macs N (2015-02-03). - * include/nuttx/net/icmpv6.h and net/icmpv6/Kconfig: Add support for - sending ICMPv6 Router Solicitation and receiving Router advertisement. - This is a part of the ICMPv6 auto-configuration logic is still not - complete (2015-02-03). - * libnx/nxfonts/nxfonts_getfont.c and nxfonts_sans39x48.h: Fixes a - problem with one of the font files. From Pierre-noel Bouteville - (2015-02-03). - * arch/arm/src/efm32/efm32_rtc_burtc.c: Remove a misbehaving assertion. - From Pierre-noel Bouteville (2015-02-03). - * net/icmpv6: Implemented the ICMPv6 Autonomous Auto-Configuration - logic. This is an IPv6 alternative to DHCP. It obtains the IPv6 - addresses and masks using ICMPv6 Router Solicitation and - Advertisement messages (2015-02-03). - * arch/arm/src/stm32/stm32_aes.c, stm32_aes.h, and - chip/stm32l15xxx_aes.h: Add driver for STM32L162XX AES peripheral. - From Juha Niskanen (2015-02-04). - * net/icmpv6/icmpv6_radvertise.c, Kconfig, and other files: Add option - to send Router Advertisement Messages (2015-02-05). - * net/icmpv6/icmpv6_input.c, arch/arm/src/tiva/tm4c_ethernet.c, and - stm32/stm32_eth.c: Add logic to behave like a router (if so - configured): NuttX will not send the router advertisement message - in response to any router solicitation messages (2015-02-05). - * configs/stm32f4discovery/ipv6 and arch/arm/src/stm32/stm32_eth.c: Add - an IPv6 configuration for the STM32F4-Discovery board (with the - STM32-DISCO_BB base board). Verify that the STM32 Ethernet driver - works with IPv6 (2015-02-05). - * net/icmpv6/icmpv6_input.c and icmpv6_rnotify.c: With these two - changes both ICMPv6 autonomous autoconfiguration and router - functionality appear to be working with no problems (2015-02-05). - * arch/arm/src/tiva and configs/tm4c123g-launchpad: Adds support for - TM4C123G timers; integrates with the TM4C123G Launchpad. From Calvin - Maguranis (2015-02-05). - * arc/arc/src/tiva/tiva_adc.c and .h: Adds a Tiva ADC driver. From - Calvin Maguranis (2015-02-05). - * tmv4c123g-launchpad: Add Tiva ADC support to the TM4C123G-Launchpad. - From Calvin Maguranis (2015-02-05). - * arch/arm/src/stm32/stm32_spi.c: The source clock for SPI 4,5, and 6 - should be PCLK2, not PCLK1 (for F411, F427, and F429). Per David - Sidrane (2015-02-07). - * drivers/syslog/syslog_console.c, include/nuttx/syslog/syslog_console.h, - and the console device initialization logic for all architectures: Add - an option to use the syslog'ing device as the system console. This - option enables a low-level, write-only console device at /dev/console - (similar to the low-level UART console device). From Pierre-noel - Bouteville (2015-02-08). - * net/utils: Clean up and consolidate some clunky stuff in ARP and - ICMPv6 time waiting logic by adding new net_timedwait() function - (2015-4-09). - * arch/arm/src/stm32/stm32_eth.c: Add logic so that STM32 Ethernet - driver can avoid interrupt level processing and, instead, execute on - the work thread (2015-4-09). - * configs/stm32f4discovery/netnsh and ipv6: Convert all STM32F4- - Discovery configurations (with base board) to configure the Ethernet - driver to use the work queue (vs. interrupt level processing) - (2015-4-09). - * libc/unisted/lib_execl.c: Fix bad logic in counting the number of - arguments. This could never have worked. Noted by Pierre-noel - Bouteville (2015-4-09). - * arch/arm/src/sama5/sam_emacb.c: Add support for Multicast address - matching and IPv6 in the SAMA5D4 Ethernet driver (2015-02-09). - * configs/sama5d4-ek/ipv6: Add a configuration for testing IPv6 with - the SAMA5D4-EK (2015-02-09). - * arch/arm/src/armv7-a/arm_doirq.c: ARMv7-A interrupt handler should not - automatically re-enable interrupts on interrupt return. That - interferes with the driver's ability to manage interrupts (2015-02-09). - * arch/arm/src/sama5/sam_emacb.c: Add support for CONFIG_NET_NOINTS in - the SAMA5D4 Ethernet driver so that the driver can operate from the - work queue thread instead of doing everything from the interrupt level - (2015-02-09). - * SAMA5D4-EK: CONFIG_NET_NOINTS is now enabled in the nsh and ipv6 - configurations (2015-02-09). - * arch/arm/src/a1x, arm, c5471, common, dm320, imx, lpc2378, lpc31xx, - sama5, str71x, hc/src.common, sh/src/common, x86/src/common, - z16/src/common, z16f, z80/src/z8: Big, very risky change: Remove all - occurrences of up_maskack_irq() that disable and enable interrupts - with up_ack_irq() that only acknowledges the interrupts. This is only - used in interrupt decoding logic. Also remove the logic that - unconditionally re-enables interrupts with the interrupt exits. This - interferes with the drivers ability to control the interrupt state. - This is a necessary, sweeping, global change and unfortunately - to test (2015-02-09). - * mtd/ramtron.c: Table of parts is not terminated properly if - CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined. Noted by David - Sidrane (2015-02-09). - * arch/arm/src/sam34/sam_emac.c, sama5/sam_emaca.c, and sama5/sam_gmac.c: - Clone the SAMA5D4 IPv6 support to the SAM4E EMAC and SAMAd3 EMAC and - GMAC drivers (2015-02-09). - * net/: Lots of build problems introduced into multiple NIC support. - Many places where conditional logic based on CONFIG_NETDEV_MULTINIC is - confused with CONFIG_NET_MULTILINK. Lots of code changed with IPv6 - that was never compiled with MULTINIC enabled. Still some problem - with parameter passing in the MULTINIC configuration(2015-02-09). - * net/iob/Kconfig: In IOB Configuration, the default number of IOB - chains must be more than zero is UDP read-ahead is enabled (2015-02-10). - * net/tcp/tcp_conn.c and udp/udp_conn.c: Fix several build errors/warning - with IPv4 + IPv6 + multiple networks are enabled (2015-02-10). - * arch/arm/src/sam34/sam_emac.c: SAM4 Ethernet driver bow supports - operation using the high priority work queue so that packet processing - can occur outside of interrupt level processing (2015-02-10). - * SAM4E-EK: The nsh configuration now configures the Ethernet driver - for execution on the HP work thread (2015-02-10). - * arch/arm/src/lpc17xx/lpc17_ethernet.c: Add IPv6 support to the LPC17 - Ethernet driver.

It is only a wrapper - around clock_settime() and does not need a trap. gettimeofday() is - no longer treated as a core OS interface (2015-02-12). - * settimeofday(): gettimeofday has been decrecated in POSIX 2008. - settimeofday() was never part of POSIX, but I decided to add it to - libc as well just for symmetry (2015-02-12). - * drivers/sensors/mpl115a.c and include/nuttx/sensors/mpl115a.h: Add - driver for the Feescale MPL115A baramoter. From Alan Carvalho de - Assis (2015-02-12). - * configs/viewtool-stm32f107: Add support for an optional, add-on - Freescale MPL115A baramoter. From Alan Carvalho de Assis - (2015-02-12). - * sched/clock/clock_systimer.c: Fix a problem in clock_systimer64 that - occurs when (1) the 64-bit system time is enabled, and (2) the value - of CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using - the tickless mode of operation). In that case, the conversion of time - to 64-bit millisecond value in clock_systmer64() causes some bad times - to be returned. Time was converted to milliseconds, then to configured - ticks. Precision was lost in the millisecond conversion. The fix is - to first convert time to a 64-bit microsecond value, then to the - configured tick value. Noted by David Sidrane (2015-02-13). - * include/nuttx/rtc.h, arch.h, and arch/*/src/*_rtc.h: Removed all of the - old, malformed RTC interface definitions from include/nuttx/rtc.h. The - necessary prototypes have been removed, renamed, scattered to the wind, - hidden under rocks, -- whatever it takes to make it clear that there is - no RTC interface callable from application code (2015-02-13). - * include/nuttx/rtc.h and fs/ioctl.h: Begin the definition of a proper, - driver based RTC interfaces that is better suited to the architectural - goals of nuttx (2015-02-13). - * drivers/timers/timer.c and watchdog.c: Move timer-related drivers from - drivers/ to drivers/timers (2015-02-13). - * drivers/timers/rtc.c: Add an RTC upper half driver. This is the driver - that is documented in include/nutt/rtc.h (2015-02-13). - * arch/arm/src/stm32/stm32_rtcc.c and stm32_rtc.h: Break out a new internal - interface, stm32_rtc_setdatetime(). This eliminates some un-necessary - time conversions. From Freddie Chopin (2015-02-13). - * arch/arm/src/stm32/stm32_rtc_lowerhalf.c, Make.defs, and stm32_rtc.h: Add - a skeleton implementation of the RTC lower half interface at - arch/arm/src/stm32/stm32_rtc_lowerhalf.c. This is just the framework for - the RTC lower half. None of the interface methods have yet been - implemented (2015-02-13). - * net/icmpv6/icmpv6_advertise.c and icmpv6_solicit.c: Add inclusion of - nuttx/net.h to two files. Without these there can be compilation errors - in certain configurations. From Max Neklyudov (2015-02-13). - * net/net_initialize.c, sched/init/os_start.c, and a few other files: - Divide net_intiialize() into net_setup() and net_initialize() to solve - a chicken-and-egg problem. net_setup() must be called before - up_initialize() is called so that networking data structures are ready - to register new network devices. net_initialize() now does only timer - related operations and is called AFTER up_initialize() where the timers - are configured. Problem note by Max Neklyudov (2015-02-14). - * include/time.h and sys/time.h: Move struct timeval from include/time.h - to include/sys/time.h where it belongs (2015-02-15). - * arch/arm/src/stm32/stm32_rtcc.c, stm32_rtc.h, and Kconfig: Extend the - RTC interface to support reading subseconds. From Jussi Kivilinna - (2015-02-16). - * arch/arm/src/efm32/efm32_usbdev.c: EFM32 USB Device is now basically - functional with this change. From Pierre-noel Bouteville (2015-02-16). - * include/nuttx/net/ip.h: Move macros and common logic for IPv4-mapped - IPv6 addresses from files in net/ to include/nuttx/ip.h. These are - currently only used for UDP, but will need to be be used in many places - in the future (2015-02-17). - * includes/nuttx/compiler.h: Add support for the restrict keyword - (2015-02-17). - * include/netdb.h: Add a mostly-commented-out version of the standard - netdb.h header file (2015-02-17). - * arch/arm/src/tiva/: Updated files to allow for ADC triggering by the - timer. I’ve cleaned up some parts of the ADC code, too, and fleshed - out the PWM triggering ioctl. From Calvin Maguranis (2015-02-17). - * configs/tm4c123g-launchpad: Add ADC support. From Calvin Maguranis - (2015-02-17). - * fs/fat/fs_mkfatfs.c: Use DMA memory for mkfatfs when needed. This makes - mkfatfs use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is - needed to ensure mkfatfs operates with boards that use DMA for microSD. - From Andrew Tridgell via the PX4/NuttX repository (2015-02-17). - * include/nuttx/rtc.h, fs/fs.h, drivers/ramdisk.c, pipes/, and - timers/rtc.c: The inode unlink method should not be support if - operations on the root pseudo-filesystem are disabled (2015-02-18). - * include/nuttx/sched timing functions: Fix some nanosecond comparisons. - Comparisons should be greate than OR EQUAL TO 1000000000 for maximum - value of nanoseconds in struct tm. From Juha Niskanen (2015-02-20). - * tm4c123g-launchpad: Add board button interrupt logic. From Calvin - Maguranis (2015-02-20). - * "Tiva: Move GPIO prototypes out of arch/arm/include/tiva/irq.h to - arch/arm/tiva/tiva_gpio.h where they belong (2015-02-20). - * arch/arm/src/tiva: Tiva GPIO clean-up by Calvin Maguranis (2015-02-20). - * arch/arm/src/stm32/stm32_pwr.c, stm32_pwr.h, and stm32_rtcc.c: Changes - to support fully write protecting the backup domain. N.B. - stm32_pwr_enablebkp did not account for the delay from enable to the - domain being writable. The KISS solution is a up_udelay. A more - complex solution would be a negated write test with restore. From - David Sidrane (2015-02-21). - * arch/arm/src/stm32/stm32_bbsram.c, stm32_bbsram.h, Kconfig, and - Make.defs: Adds the ability to use the STM32F2 and STM32F4 Battery - Backedup SRAM in the file system. With an option to Save Panic - context to one of the files. From David Sidrane (2015-02-21). - * configs/pic32mx-starterkit: Rename from pic32-starterkit to make - room on the namespace for a pic3mz-starterkit. Update src/ directory - file naming to match current standard. Refresh configurations. Move - linker scripts to a new scripts/directory. Make sure that it builds - using the Pinquino toolchain (2015-02-21). - * arch/mips/src/mips32/Toolchain.mk: Current Pinguino toolchain uses - the prefix p32- instead of mips- (2015-02-21). - * configs/pic32mz-starterkit: Add basic board support for the PIC32MZ - (can't build yet of course because there is not yet any PIC32MZ - support) (2015-02-22). - * arch/mips/src/pic32mz and include/pic32mz: Add some PIC32MZ header - file definitions and just enough logic in the source directory so - that we can run 'make menuconfig'. Still a very long way from being - complete (2015-02-22). - * libc/time/lib/lib_sfrtime.c: Missing implementation of %C in - sfrtime() C (was being treated as %y). From Freddie Chopin - (2015-02-23). - * drivers/can.c: In the can_open function: this line - 'dev->cd_ocount = tmp;' needs to be moved a few lines down otherwise - the open count will only be incremented from 0 to 1. This causes - problems when trying to open the can bus from two different tasks. - SourceForge Patch #46 from Anonymous (2015-02-23). - * Tiva TM4c1294: Updates from Frank Sautter (2015-02-24). - * fs/aio: correct some backward tests in aio_read() and aio_write(): - Socket descriptors have higher numbers than file descriptors. In - aio_contain(), Copy u.ptr (void *) when initializing aioc and not - the case specific u.aioc_filep. From Michal Ulianko (2015-02-24). - * include/pthread.h: Fix PTHREAD_COND_INITIALIZER (2015-02-24). - * sched/clock/clock_systimespec.c: When an RTC is used clock_systimespec() - must subtract the basetime from the returned time. It needs to - return the time since power up, no the current time. Issue noted - by Max Neklyudov (2015-02-25). - * fs/vfs/fs_select.c and sched/semaphore/sem_timedwait.c: Fix places - where the errno value was being overwritten by subsequent actions so - that the returned errno value was incorrect. From Max Neklyudov - (2015-02-25). - * include/sys/select.h: Extend the fd_set type definition so that it - can handle more than 32 descriptors (if so configured). From Max - Neklyudov (2015-02-25). - * net/netdev/netdev_unregister.c: Fix a list handling error in - netdev_unregister(). From Max Neklyudov (2015-02-27). - * net/netdev/netdev_register.c: Improve the network device registration - logic. When multiple link types are used, modify how each interface - number is assigned to the device name by incrementing the device - number individually for each interface link type. From Max Neklyudov - (2015-02-27). - * include/nuttx/board.h: Remove common board function prototypes from - other files and consolidate them in this new header file (2015-02-27). - * arch/mips/src/pic32mz/: Implement support IO port interrupts - (2015-03-01). - * configs/pic32mz-starterkit/src: Add support for on-board buttons - (2015-03-01). - * include/nuttx/spi/spi.h: Add an SPIDEV_USER so that there can be - board-specific definitions of SPI devices (2015-03-01). - * arch/arm/src/stm32 and arch/arm/src/stm32: Adds architecture support - for the STM32F372 and F373 (no board support yet). Only tested on - STM32F373CC, but should work on the rest. Contributed by Marten - Svanfeldt (2015-03-01). - * arch/mips/src/pic32mz/pic32mz-spi.c and chip/pic32mz-spi.h: Add - support for a basic SPI driver for the PIC32MZ (2015-03-03). - * include/nuttx/i2c.h: Add a user provided void * argument to the - I2C callback method for the I2C slave interface. Suggested by - Nate Weibley (2015-03-03). - * crypto/, include/nuttx/crypto, and arm/src/common/up_initialize.c: - Fix issues when AES support was added for the STM32L1. From Juha - Niskanen (2015-03-04). - * arch/arm/src/stm32/stm32_spi.c and .h: Add missing SPI callback - functions to the STM32 SPI driver. From Freddie Chopin (2015-03-04). - * arch/*/src/*/*_assert.c, configs/Kconfig, and include/nuttx/board.h: - Add support for dumping board-specific information on assertion. - From David Sidrane (2015-03-04). - * drivers/spi/Kconfig: Add missing CONFIG_SPI_CALLBACK selection. Noted - by Freddie Chopin (2015-03-04). - * arch/arm/src/samv7 and include/samv7: Add basic build directories - and configuration logic for the Atmel SAMV7 family (2015-03-05). - * arch/arm/src/Makefile, armv7-m/Toolchain.defs: Make ARM build system - Cortex-M7 ready (2015-03-05). - * arch/arm/src/sam34/sam_start.c: Leverage start-up logic from STM32 - to (1) Enable the FPU and (2) perform IDLE stack coloration - (2015-03-05). - * arch/arm/src/armv7-m/up_lazyexception.S, Kconfig and severl other - files: Add support for lazy FPU state saving. Not yet verified. - (2015-03-06). - * arch/arm/Kconfig, Make.defs, sam_start.c, configs/Kconfig, - samv71-xult: Add a bare bones framework that will do nothing more than - support configuration for the Atmel SAMV71 Xplained Ultra board. Very - much a work in progress (2015-03-06). - * sched/mqueue/mq_timedsend.c: Should not check for valid time if - there is space in the message queue. Noted by Freddie Chopin - (2015-03-10). - * arch/arm/src/tiva/tiva_timerlib.c: Fix a typo in peripheral wait - logic: gptm, not gpio. From Bradley Noyes (2015-03-10). - * drivers/net/tun.c, Make.defs, include/nuttx/net/net.h, tun.h, and - net/Kconfig: Add TUN device. From Max Neklyudov (2015-03-11). - * fs/fat/fs_fat32.c: fat_unbind() was accessing 'fs->fs_sem' after - freeing the 'fs' struct. From Juha Niskanen (2015-03-11). - * fs/procfs/fs_procfsproc.c: fs_procfsproc: Fix potential NULL pointer - dereference of 'node'. From Juha Niskanen (2015-03-12). - * sched/sched/sched_waitpid.c: Do not use uninitialized boolean in - waitpid(). From Juha Niskanen (2015-03-12). - * libc/stdio/lib_ungetc.c:Fix NULL pointer dereference in ungetc(). - If 'stream' was NULL, 'stream->fs_oflags' was evaluated. From Juha - Niskanen (2015-03-12). - * arch/arm/src/stm32/stm32_i2c.c: Add missing NULL check. From Juha - Niskanen (2015-03-12). - * drivers/usbdev/usbmsc_scsi.c: Add NULL pointer check. From Juha - Niskanen (2015-03-12). - * drivers/bch/bchdev_driver.c: Avoid NULL pointer dereference when - bch->refs == 255. From Juha Niskanen (2015-03-12). - * arch/arm/src/armv7-m/mpu.h: Bad syntax in ARMv7-M MPU logic would - cause failure to write the correct value to the MPU_RASR register. - From Juha Niskanen (2015-03-12). - * net/socket/net_dupsd.c: Do not call sockfd_socket() twice. From - Juha Niskanen (2015-03-12). - * arch/arm/src/stm32/stm32_usbdev.c: Fix stale initialization - invalidating later NULL check. From Juha Niskanen (2015-03-12). - * arch/arm/src/stm32/stm32_serial.c and chip/stm32f10xxx_dma.h: Fix - RX DMA setup for UART5. From Jussi Kivilinna (2015-03-13). - * arch/arm/src/stm32/stm32_serial.c: Make input hardware flow-control - work with RX DMA. From Jussi Kivilinna (2015-03-13). - * drivers/pipes/pipe_common.c: Fix zero-lenth writes to pipes/FIFOs. - From Jussi Kivilinna (2015-03-13). - * drivers/serial/serial.c: Report correct number of bytes free in - serial buffer with FIONWRITE. From Sami Pelkonen via Jussi Kivilinna - (2015-03-13). - * drivers/mmcsd/mmcsd_spi.c: Debugging and manuals (this one - https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf - and this one https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf) - shows that ACMD23 must be preceded with CMD55 command as any other - ACMD commands. Also, after the block reading wait loop must be - inserted before writing the next block of data to the sd card. From - Dmitry Nikolaev via Jussi Kivilinna (2015-03-13). - * arch/arm/src/efm32/efm32_i2c.c: Add I2C driver. From Pierre-noel - Bouteville (2015-03-14). - * fs/mount/, include.sys/mount, syscall/: Add umount2(). umount() is - now a macro that just calls umount2() with flags = 0 (2015-03-14). - * fs/mount/fs_umount2.c, all file systems, include/nuttx/fs/fs.h: Pass - the umount2() flags to every unbind() implementation. That is where - the decision to umount or not will be made (2015-03-14). - * fs/fat/fs_fat32.c: Fix a bug in the FAT unbind() logic. There were - problems with the way certain internal list handling was implemented. - The end result is that newly opened or cloned file structures were - never being added to the list of open files. So when the unmount() - happens, it always looked like there were not open files and a crash - could ensue (2015-03-14). - * fs/fat/fs_fat32.c and fs_fat32.h: Add support for umount2(target, - MNT_FORCE) in the FAT file system (2015-03-15). - * drivers/mmcsd/mmcsd_sdio.c: Fix some bad logic when file system debug - is turned on: Arguments to syslog were missing so that garbage was - being printed (2015-03-15). - * arch/arm/src/sama5/sam_hsmci.c: Fix a bug in SAMA5 HSMCI. The - bitfield mask and shift values were reversed resulting in a trashed - value for the number of blocks in the BLOCKR register. This was - sufficient to prevent DMA writes from working (2015-03-15). - * drivers/mtd/at24xx.c, Kconfig, and include/nuttx/fs/ioctl.h: Add - support for (1) the byte-oriented read() method, (2) devices that - have extended memory regions, and (3) devices that use 8-bit - addressing (2015-03-17). - * arch/mips/src/mips32/Kconfig, Toolchain.defs, and - configs/pic32mz-starterkit/nsh/Make.defs: Changes that will permit - building of the PIC32MZ Start Kit configuration using MPLAB and the - XC32 toolchain. From David Sidrane (2015-03-17). - * arch/arm/src/stm32/stm32_rtc_lowerhalf.c: Fix some errors in the - STM32 RTC lower-half driver that cause compilation failures. From - shilo.xyz (2015-03-19). - * arch/arm/src/sama5/chip/sam_tc.h: Fix typos in timer/counter header - file. From Bob Doiron (2015-03-20). - * configs/olimexino-stm32: Board support for the Olimexino STM32 board - from David Sidrane (2015-03-20). - * PIC32MZ: Incorporated a set of patches that makes the basic NSH - configuration on the PIC32MZ Starter Kit. From Kristopher Tate - (2015-03-22). - * arch/arm/src/tiva: (1) ADC driver has been re-organized; configuration - is now handled in code instead of Kconfig to help reduce bloat and - confusion. (2) Timer changed to remove ADC coupling in Kconfig to code - and moved configuration up from arch/arm/src/tiva to - configs/tm4c123g-launchpad/src. (3) GPIO driver needed small fixes in - the configuration routines and discovered false-positive bugs in - interrupt testing: interrupts are now verified to actually be working - reliably. (4) Attempt to apply some consistency in the tiva arch/ - level's interface to the config/board/ level driver configuration. - From Calvin Maguranis (2015-03-23). - * arch/mips/src/pic32mz: Various fixes for Ethernet support. Still - not fully functional. From Kristopher Tate (2015-030-29). - * arch/arm/src/armv7-m: Add configuration option and logic to support - the D-Cache in write-through mode (2015-03-29). - * arch/arm/src/stm32/Kconfig, stm32_lse.c, stm32_lsi.c, stm32_rtc.c/.h, - stm32_rtcc.c, stm32_rtcounter.c, and stm32f*_rcc.c: The - STM32F4Discovery board doesn't come with a Low speed external - oscillator so the default LSE source for the RTC doesn't work. In - stm32_rtcc.c the up_rtc_initialize() logic doesn't work with the LSI. - The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call - that rightfully enables the lsi clock; but the next times, when the - rtc is already setup, the rtc_resume() call does NOT start the lsi - clock! The right place to put LSE/LSI initialization is inside - stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked - the possible uses of the LSI and the LSE sources: the LSI can be used - for RTC and/or the IWDG, while the LSE only for the RTC (and to output - the MCO1 pin). This change is not verifed for any other platforms. - From Leo Aloe3132 - * Rename arch_nshinitialize() to board_app_initialize() (2015-03-30). - * ./*.mk, configs/.gitignore, Makefile, boardctl.c, include/nuttx/fs/ioctl, - include/sys/boardctl.h, syscall.h, and syscall/: Add a new non- - standard OS interface called boardctl(). This is similar to a driver - IOCTL call. But this is an IOCTL call directly on the board logic. - This function will eventually replace all of the ad hoc OS interfaces - that are current used to perform application specific initialization - and application driver test configuration. It essentially formalizes - and institutionalizes these rogue interface in to at least a single - crazy call (2015-03-31). - * configs/: Modify all configurations: Make sure that - CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears. - Remove support for CONFIG_NSH_ARCHMAC. It is not used and there are - better ways to do that operation (2015-03-31). - * configs/Kconfig, boardctl.c, all touchscreen driver setup functions, - include/board.h, include/sys/boardctl.h, and - include/nuttx/input/touchscreen.h: arch_tcinitialize() and - arch_tcunitinitialize() renamed to board_tsc_setup() and - board_tsc_teardown(). These are not long called directly by - applications but only indirectly throught the crappy boardctl() OS - interface (2015-03-31). - * configs/Kconfig, boardctl.c, include/nuttx/board.h, include/sys/boardctl.h, - and several ADC files in configs//src/: Rename adc_devinit() to - board_adc_setup(). Add support to the boardctl() interface so that it - can call board_adc_setup() on behalf of an application. Make sure that - the proper features are enabled in the defconfig files that have - CONFIG_EXAMPLES_ADC=y (2015-03-31). - * configs/*/defconfig: Make sure that all defconfig files that require - external graphics intiialization also enable the correct boarctl() - settings (2015-03-31). - * include/nuttx/board.h, include/sys/boardctl.h, nuttx/configs/Kconfig and - boardctl.c, and board configurations and PWM implementations: Rename - pwm_devinit() to board_pwm_setup(). Add CONFIG_BOARDCTL_PWMTEST that - will enable calling board_pwm_setup() from boardctl(). In all - configurations that enable the apps/examples/pwm test, make sure that - boardctl() support is properly enabled (2015-03-31). - * Move include/nuttx/timer.h, rtc.h and watchdog.h to include/nuttx/timers/. - (2015-04-01). - * drivers/timer/cs2100-cp.c and include/nuttx/timers/cs2100-cp.h: Add a - very basic driver for the CS2100-CP Fractional-N Multipler chip (2015-04-02). - * configs/, graphics/, include/nuttx: More renaming: up_lcdinitialize->board_lcd_initialize, - up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize - (2015-04-04). - * include/nuttx/nx, libnx/nx, libnx/nxtk: Add a new 'capped' parameter to - nx_drawline(), nxtk_drawlinetoolbar(), and nxtk_drawlinewindow() - (2015-04-05). - * libnx/nx/nx_drawline.c, libnx/nxtk/nxtk_drawlinetoolbar.c and - nxtk_drawlinewindow.c: Implement line caps by drawing a file circle at - the each endpoint of a line with a radius equal to half of the width - of the line (2015-04-05). - * include/time.h, nuttx/time.h, libc/time/lib_dayofweek.c and - lib_gmtimer.c: Implements CONFIG_TIME_EXTENDED as we discussed - relative to providing the last 3 members of the tm struct and support - for filling them in and even using the wday in the STM32 RTC. From - David Sidrane. - * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: A side-effect - of changing serial settings via TERMIOS (such as tcsetattr) is that - serial interrupts were being left disabled. This is not a problem if - the serial configuration is changed when there are no open references - to the serial device. In that case, serial interrupts are disabled and - will not be enabled enabled until the serial device is first opened. - But it is fatal if the serial device is already opened and if there is - a task waiting to receive data. In that case, the side-effect of - disabling interrupts is fatal: That task is then left hanging with - interrupts disabled (2015-04-08) - * arch/arm/src/sama5/sam_serial.c: Backport support for flowcontrol and - termios from SAM3/4 -- UNVERIFIED. (2015-04-08). - * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: The IMR - register is read-only. This means that sam_restoreints() did not - actually re-enable UART interrupts (2015-04-08). - * sigaddset() and sigdelset(): Need to set errno if a bad signal number - is received (2015-04-09). - * sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New - signal handling functions (2015-04-09). - * Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all - exhibited bad cancellation errors near zero (<= 1E-10). This can be - easily seen e.g. with x = 1E-30, the results are all zero though they - should be extremely close to x. The cutoff values (1E-5, 1E-9) are - chosen so that the next term in the Taylor series is negligible (for - double). Functions could maybe be optimized to use only first term (x) - and a smaller cutoff, just bigger than where the cancellation occurs - (2015-04-09). - * syscall/syscall.csv: Last changes to message queue prototypes did not - make it into call gate logic (2015-04-09). - * syscall/syscall_stublookup.c: Fix some errors that crept in recently - (2015-04-09). - * libc/time/lib_localtime.c: Inconsistent configuration name: - CONFIG_LIBC_TZDIR vs CONFIG_LIBC_TZ_TZDIR. Former wins (2015-04-11). - * libc/time/lib_calendar2utc.c and lib_mktime.c: Fix an error in time - initialization when there is not RTC and the time is initialized from - a fixed configured value. The call to clock_calendar2utc() was - returning the time in units of seconds. The initialization logic, - however, was expecting to get time in units of days.

LTDC only controls the - display visibility but the DMA2D controller changes the content of the - frame buffer (buffer of the layer). - - The main features are: - - 1. DMA2D interface - Supports the nuttx pixel formats: - - FB_FMT_RGB8 - - FB_FMT_RGB24 - - FB_FMT_RGB16_565 - Dynamic layer allocation during runtime for the supported formats - - The number of allocatable layer can be configured. - Supported dma2d operation: - - blit (Copy content from source to destination layer) also works - with selectable area. - - blend (Blend two layer and copy the result to a destination layer - which canbe a third layer or one of the source layer) also works - awith selectablerea. - - fillarea (Fill a defined area of the whole layer with a specific - color) - - As a result of that the dma2d controller can't transfer data from the - core coupled memory, CCM is disabled but usable by the ccm allocator. - Currently the ccm allocator is used for allocating the layer structure - only. For the dma memory (layers frame buffer) memory is allocated from - heap 2 and 3. - - 2. LTDC interface - I have changed the api for the currently non implemented operations: - - blit (Copy content from a dma2d layer to an ltdc layer) also works with - selectable area. - - blend (Blend two dma2d layer and copy the result to a destination ltdc - layer) also works with selectable area. - - Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer - is a layer referenced by the dma2d interface. - - One of the most important questions for me was, How can i flexible use an - ltdc layer with the dma2d interface, e.g. as source layer for dma2d - operations? - Get the layer id of the related dma2d layer by a special flag when using - getlid() function of the ltdc interface and use the layer id to reference - the specific dma2d layer by the dma2d interface. - - The ltdc coupled dma2d layers are predefined and can't be dynamically - allocated of freed. They use the same frame buffer memory and the same - color lookup table. - - Changes: - - layer internal format of the clut table - - interrupt handling for register reload (vertical vblank) instead using - waiting loop - - small fixes and refactoring - From Marco Krahl (2015-04-16). - * Add support for the new DMA2D features to the STM32F429i-Disco LTDC - configuration.

This cause major problems in unlucky builds - where the USB host buffers where unaligned and abutting other data. - The cache flush and invalidate operations could be subverted by - accesses to adjacent data or could have unexpected side effects.

This happens because RX interrupt - was disabled in the setup routine. To fix this I save interrupt - configuration before UART shutdown and restore it after. From Max - Neklyudov (2015-05-21). - * arch/arm/include/lpc11xx and src/lpc11xx: Support for the LPC11xx - family (the LPC1115 MCU in particular).

Update README with OpenOCD instructions. - From Alan Carvalho de Assis (2015-05-23). - * Fix numerous typos in configuration variable names. Tracked down - by Alan Carvalho de Assis (2015-05-23). - * configs/teensy-2.0: Rename configs/teensy so that it is clearly - distinguished from teensy-lc and teensy-3.1 (2015-05-15). - * include/nuttx/mtd/mtd.h: Increase the size of the fields in the - geometry structure (again) to support larger FLASH sizes. Needed - by Sbastien Lorquet (2015-05-26). - * SAM4CM and SAMA5D Free-running timer: Logic that samples the free - running counter reads the pending interrupt status register and - can cause interrupts to be lost. So, if when the status register - is read, the logic must also handle the timer overflow event. - Found and fixed by Max Neklyudov (2015-05-26). - * arch/arm/include/kinetis and arch/arm/src/kinetis: Basic support - for the Kinetis K20 architecture. Taken from PX4. This is the - work of Jakob Odersky (2015-05-26). - * net/: Move some ICMP event lists to the device structure. That - allows for both device-specific event processing and also devices - to generate events like network down. From Max Neklyudov (2015-05-27). - * net/: Extend Macs logic to ARP and ICMPv6. Also found and fix - several IPv6-related compilation errors that have crept in. IPv6 - has been broken for awhile (2015-05-27). - * net/tcp: Fix an important TCP networking bug: 16-bit flags was - being converted to 8-bits in a few locations, causing loss of - status indications (2015-05-27). - * net/socket and net/tcp: net_startmonitor.c always returned OK. In - the case where a socket has already been closed, it correctly handled - the disconnection event but still returned OK. Returning OK caused - the callers of net_startmonitor to assume that the connection was - okay, undoing the good things that net_startmonitor did and causing - the socket to be marked as connected. This behavior was noted by - Pelle Windestam (2015-05-28). - * include/nuttx/net, net/arp, net/devif, net/icmp, net/icmpv6, - net/netdev, net/pkt, net/tcp, net/udp: Modify event list handling: - Now there are two event lists each device structure: (1) One is - for ARP and ICMP data related events, the other is for device - related events. Callback allocation/free routines no accept a - device parameter as well as a list: If the device parameter is - added, then the callback goes into both the connection-related - list AND the device event list. Thus each socket type can - received both custom data-related events as well as common - device related events (2015-05-28). - * net/socket and net/utils: setsockopt() fails when setting timeouts - to values less that an 100 msec. That is because the timeout is - limited to stops of 1 decisecond and because the conversion of - structure timeval was truncating the microsecond remainder. The - utility net_timeval2dsec now accepts and option to determine how it - handles the remainder: truncate, discarding the remainder, use the - remainder to round to the closed decisecond value, or use any non-zero - remainder to the next larger whole decisecond value. Bug discovered - by Librae (2015-05-29). - * configs/stm32f4discovery/src: Move up_cxxinitialize from - nuttx/configs/stm32f4discovery/src to apps/platform/stm32f4discovery - where it belongs (2015-05-29). - * net/sockets, net/tcp, net/udp: UDP Networking: Add support for - device event notification for UDP transfers (2015-05-29). - * net/sockets and net/tcp: TCP Networking: Add support for device event - notification for UDP transfers (2015-05-30). - * libc/Kconfig and stdio/lib_libvsprintf.c: Add an option to disable - support for long long formats in lib_vsprintf. From Alan Carvalho - de Assis (2015-05-30). - * net/net_initialize.c, net/detdev, and net/socket: The network device - list was protected by a re-entrant semaphore. With the recent change - to support network device callback, the network stack needs to access - the network device list too. Some drivers, however, run the network - stack from the interrupt level -- this is bad but a fact in the - current state. Of course, those drivers are unable to take the - semaphore and would assert. - The solution here is to eliminate the device devices semaphore - altogether. This eliminates netdev_semtake() and netdev_semgive() - and replace them with net_lock() and net_unlock() which have the - larger scope that is needed and will integrate properly with the - dinosaur interrupt driven stack (2015-05-31). - * net/socket/connect.c: In the TCP connection operation, it was trying - to setup the network monitor BEFORE the socket was successfully - connected. This, of course, has ALWAYS failed because the socket is - not yet connected and the TCP state is not yet correct for a connected - socket. However, because of other changes net_startmonitor() now - returns a failure condition that causes worse problems when trying to - connect. The fix is to move the logic that starts the network monitor - to AFTER the socket has been successfully connected (2015-05-31). - * tools/configure.c: Fix test for the existence of the apps/ directory. - Fix backward interpretation of options, -l was selecting Windows and - -w was selecting Linux. This was SourceForege Ticket #39 (2015-05-31). - * arch/include/stm32/chip.h and arch/src/stm32/Kconfig: Add basic - support for the STM32F205RG. From SourceForge Ticket 40 (anonymous, - 2015-05-31). - * arch/arm/src/lpc17xx: Review, update, and modify the Ethernet driver - so that it works better with CONFIG_NET_NOINTS=y (2015-06-01). - * configs/: Update all LPC17xx networking configurations so that they - have CONFIG_NET_NOTINTS=y selected (2015-06-01). - * /arch/arm/src/armv7-m, binfmt/libelf, configs/stm32f4discovery/scripts, - /include/nuttx/binfmt, and libxx: Add support uClibc++ exceptions. This - involves additional handling for relative relation types, additional - support for unwinding, as well as additional changes. The culmination - of a big effort from Leo Aloe3132 (2015-06-01). - * configs/olimex-lpc1766stk: Rename the thttpd configuration to thttpd-nxflat. - Add a new configuration, thttpd-binfs, that provides an example of how - to build apps/netutils/thttpd using binfs instead NXFLAT+ROMFS - (2015-06-02). - * tools/cfgdefine.c: Extend the mkconfig tool so that it can dequote a - quoted list of quoted strings. THTTPD uses such a configuration - setting to provide the list of index files (2015-06-02). - * mq_timedreceive(): move the location where the errno value is set; the - ETIMEDOUT errno setting was being overwritten by subsequent actions - before returning. Noted by Freddie Chopin (2015-06-03). - * Networking: Modify how callback structures are stored to avoid - another potential use of a stale pointer (2015-06-03). - * POSIX message queues: Move mq_setattr() and mq_getattr() from - nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support - for mq_setattr() and mq_getattr(). This is necessary in protected and - kernel builds because in those cases the message queue structure is - protected and cannot be accessed directly from user mode code (2015-06-03). - * drivers/net/tun.c: TUN driver bug fix. From Max Neklyudov (2015-06-03. - * drivers/net/Kconfig, include/nuttx/net/mii.h, and - arch/arm/src/lpc17xx/lpc17_ethernet.c: Add support for the Micrel - KSZ8041 PHY to the LPC17xx Ethernet driver (2015-06-03). - * configs/lincoln60/netnsh: Add a network enabled configuration for - the Lincoln60 board (2015-06-03). - * drivers/net/tun.c: Misc. improvements to the TUN driver, mostly related - to poll().

From Alessandro Temil (2015-07-09). - * mm/umm_heap, include/nuttx/kmalloc.h, userspace.h, mm/mm.h, and all - configurations that support protected mode: Redesigned how the user - space heap is accessed from the kernel code in protected mode. It - used to call memory management functions in user space via function - pointers in the userspace interface. That is inefficient because the - first thing that those memory management functions do is to trap back - into the kernel to get the current PID. Worse, that operation can be - fatal is certain fragile situations such as when a task is exiting. - The solution is to remove all of the memory management function calls - from the interface. Instead, the interface exports the users pace - heap structure and then kernel size implementations of those memory - management functions will operate on the userspace heap structure. - This avoids the unnecessary system calls and, more importantly, - failures do to freeing memory when a test exits (2015-07-10). - * libc/netdb: Move netdb functions from lib/net to lib/netdb.

From Paul - Alexander Patience (2015-08-17). - * include/nuttx/can.h and all CAN drivers: Add an error indication - bit to the CAN message report. This indication must then be cleared - in all existing drivers. More to come (2015-08-18). - * arch/arm/src/lpc17/lpc17_irq.c: Set NVIC vector address so that - code can execute with a bootloader or can execute from RAM. From - Pavel Pisa (2015-08-20). - * All ARMV7-M IRQ setup: Always set the NVIC vector table address - unconditionally. This is needed in cases where the code is running - with a bootload and when the code is running from RAM. It is also - needed by the logic of up_ramvec_initialize() which gets the vector - base address from the NVIC. Suggested by Pavel Pisa (2015-08-21). - * SAMV7 USBHS DCD: The device controller driver is (finally) functional - (2015-08-21). - * recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is - enabled.

From Pavel Pisa - (2015-08-21). - * sched/wdog/wd_create.c: Correct a counting error in the number - of available watchdog timers. When the number of free timers is - low, the counter could be incremented below zero (2015-08-21). - * arch/arm/src/stm32: Add OTG support for STM32F44x. From David - Sidrane (2015-08-21). - * arch/arm/src/lpc17: Actually implement options to use external - SDRAM and or SRAM for the heap. From Pavel Pisa (2015-08-21). - * gethostbyname(): correct returned address format when DNS is used. - The hostent.h_addr_list should point to raw in_addr or in6_addr - as defined in the standard. Original implementation used that - for numeric addresses but for DNS lookup returned pointer to - whole sockaddr_in or sockaddr_in6. From Pavel Pisa (2015-08-21). - * tools/mksymtab: declare g_symtab array as const to occupy RO - section (Flash).

Originally - planned to use the SPI interface, but it is just now compatible - with the SAMV71 QSPI hardware (2015-08-25). - * drivers/rwbuffer.c: Fix some logic errors. From Dmitry Nikolaev - via Juha Niskanen (2015-08-26). - * net/socket and net/tcp: Fix a problem in when there are multiple - network devices. Polls were being sent to all TCP sockets before. - This is not good because it means that packets may sometimes be - sent out on the wrong device. That is inefficient because it - will cause retransmissions and bad performance. But, worse, when - one of the devices is not Ethernet, it will have a different MSS - and, as a result, incorrect data transfers can cause crashes. - The fix is to lock into a single device once the MSS is locked - locked down (2015-08-27). - * drivers/lcd and include/nuttx/lcd: Add SSD1351 OLED controller - support. Contributed by Paul Alexander Patience (2015-08-28). - * include/nuttx/mtd/mtd.h: Move MTD ioctl command definitions from - include/nuttx/fs/fs.h to include/nuttx/mtd.h.

From Bruno Herrera (2015-08-30). - * arch/arm/src/up_internal.h and several ARM Make.defs files: In the - original implementation, !defined(CONFIG_ARMV7M_CMNVECTOR) was a - sufficient test to determine if lazy floating point register saving - was being used. But recents changes added common lazy register as - well so now that test must be (!defined(CONFIG_ARMV7M_CMNVECTOR) || - defined(CONFIG_ARMV7M_LAZYFPU)) (2015-08-31). - * arch/arm/include/sama5 and src/sama5: Add basic chip description, - configuration support and interrupt definitions for the SAMA5D2 - (2015-08-31). - * LPC43xx: Fix NVIC_SYSH_PRIORITY_STEP define. From Ilya Averyanov - (2015-09-01). - * LPC43xx: Fix missing #define in eeprom. From Ilya Averyanov - (2015-09-01). - * libc/math/lib_asin.c: The function did not convert for some input - values. Asin did not convert for values which do not belong to the - domain of the function. But aside of that the function also did not - converge for some allowed values. I achieved a conversion of the - function by reducing the DBL_EPSION and by checking if the input - value is in the domain of the function. This is a fix for the - problem but the function should always terminate after a given - number of iterations. From Stefan Kolb (2015-09-01). - * arch/arm/src/lpc43xx/lpc43_spi.c: Fix SPI driver. From Ilya - Averyanov (2015-09-02). - * arch/arm/src/lpc43xx/lpc43_ethernet.c: Add Ethernet support. From - Ilya Averyanov (2015-09-02). - * net/tcp: The logic that binds a specific network device to - a connection was faulty for the case of multiple network - devices. On bind(), the local address should be used to associate - a device with the connection (if the local address is not INADDR_ANY); - On connect(), the remote address should be used (in case the local - address is INADDR_ANY). On accept(), it does not matter but the - remote address is the one guaranteed to be available (2015-09-02). - * configs/Board.mk and configs/*/src/Makefile: Simplify configs/ - Makefiles by combining common logic into a new Board.mk Makefile - fragment. From Paul Alexander Patience (2015-09-04). - * configs/sama5d2-xult: Add a very basic configuration for the SAMAD2 - Xplained Ultra board. This configuration is incomplete and only - intended to support the initial board bring-up (2015-09-05). - * up_initialize() all architectures: Automatically initialize all - the TUN device if it is in the configuration (2015-09-06). - * Change all references from avsprintf to vasprintf.

This provides only the framework for - the shutdown function; the internal logic is not included - (2015-09-09). - * configs/nucleo-f303re: Support for the STMicro Nucleo F303RE board - from Paul Alexander Patience (2015-09-10). - * arch/arm/src/lpc43xx/lpc43_ehci.c and .h: LPC43xx EHCI driver from - Ilya Averyanov (2015-09-10). - * ARMv7-M, all "lazy" interrupt stack logic. Assembly instruction - that fetches the saved value is incorrect; replace with more - traditional push and pop. This is an important fix. Noted by - Stefan Kolb (2015-09-14). - * All ARMV7-M: Force 8-byte stack alignment when calling from assembly - to C to interrupt handling (2015-09-15). - * drivers/power/battery_gauge.c and include/nuttx/power/battery_gauge.h: - battery.c/h renamed to batter_gauge.c/.h since it really only - implements a battery fuel gauge. From Alan Carvalho de Assis (2015-09-19). - * drivers/power/battery_charger.c and include/nuttx/power/batter_charger.h: - Add a new framework to support a batter charger interface.

Those that do only - support them when DEBUG is enabled. Each driver collects an - architecture specific set of statistics and there is no mechanism in - place to view those statistics. Thus, the driver feature was mostly - useless. This change standardizes the driver statistics and puts the - definition in the common network device structure defined in netdev.h - where they can be accessed by network applications. All Ethernet - drivers that collect statistics have been adapted to use these common - statistics (2015-11-26). - * net/net_procfs.c: Add basic support for networking entries in the - procfs (2015-11-27). - * mtd/filemtd.c and smart.c: Add support for a /dev/smart loop device. - From Ken Pettit (2015-11-28). - * sched/pthread/: CRITICAL BUGFIX: Logic was wiping out the indication - that of the type of a pthread.

It is a driver a belongs in the OS. There are still - some interface related issues, however (2015-12-07). - * configs/: Update all configurations that use the Telnet daemon; those - configurations now need to separately enable the Telnet drvier - (2015-12-07). - * drivers/net/telnet.c: Now works like the loop device. A new interface - called telnet_initialize() registers a telnet session "factory" - device at /dev/telnet. Via ioctl, the factory device can create - instances of the telnet character devices at /dev/telnetN to support - Telnet sessions (2015-12-07). - * arch/arm/src/samv7: In USBHS device driver, fix check if zero length - packet is needed (2015-12-08). - * sched/pthread/: CRITICAL BUGFIX: Logic was wiping out the indication - that of the type of a pthread.

This initial implementation will only work in the - FLAT build. See the top-level TODO file for additional details - (2015-12-30). - * include/nuttx/compiler.h, include/nuttx/streams.h include/stdio.h - include/syslog.h libc/stdio/, and libc/syslog: introduce support for - Atmel toolchain in-flash strings. Atmel toolchain AVR compiler - provides a transparent in-flash object support using __flash and - __memx symbols. The former indicates to compiler that this is a flash- - based object. The later used with pointer indicates that the referenced - object may reside either in flash or in RAM. The compiler automatically - makes 32-bit pointer with flag indicating whether referenced object is - in flash or RAM and generates code to access either in run-time. Thus, - any function that accepts __memx object can transparently work with RAM - and flash objects. - For platforms with a Harvard architecture and a very small RAM like AVR - this allows to move all constant strings used in trace messages to flash - in the instruction address space, releasing resources for other things. - This change introduces IOBJ and IPTR type qualifiers. The 'I' indicates - that the object may lie in instruction space on a Harvard architecture - machine. For platforms that do not have __flash and __memx or similar - symbols IOBJ and IPTR are empty, making the types equivalent to, for - example, 'const char' and 'const char*'. For Atmel compiler these will - become 'const __flash char' and 'const __memx char*'. All printf() - functions and syslog() functions are changed so that the qualifier is - used with the format parameter.

From Hang - Xu (2016-01-25). - * drivers/ioexpander/pca9555.c: Fixed a bug in the function pca9555_setbit - which occurs if someone tries to set one of the pins 8-15. The problem is - that after the check if the pin is greater than 7 the variable addr is - incremented and used in the Call I2C_WRITEREAD. But later in the call to - the I2C_WRITE buf[0] is used as address but this address is not incremented - as it should be.

Back last December, a fix was - put in for this but the fix apparently worsens the problem; now causing - hangs. The basic problem is that the number of busy banks (NBUSYBKS) - status is not real time but is delayed. This was fixed; now when the DMA - completes and NBUSYBKS > 0, the NBUSYBK is interrupt is enabled and the - operations are deferred until NBUSYBKS is truly zero (2016-03-17). - * net/tcp/tcp_timer.c: Fix some logic when there are multiple network - interfaces. In this case, TCP timeout events can really only being - processed when the poll from the correct device is received (2016-03-20). - * sched/wqueue/kwork_signal.c: Fix logic to find an IDLE worker thread; - the test for busy was backward.

From Dave (2016-03-25). - -7.16 2016-06-01 Gregory Nutt - - * PM: Add activity domain to all PM interfaces and driver callbacks. If - CONFIG_PM_NDOMAINS == 1, then the legacy behavior is preserved. If - CONFIG_PM_NDOMAINS > 1, then multiple PM domains are supported. This - will allow separate control for certain power management groups. For - example, a network can be shut down without affect an ongoing UI (and - vice versa) (2016-03-27). - * apps/configs/vsn: Removed the VSN configuration from the main NuttX - repository. The VSN can still be found in the Obsoleted repository - (along with a full explanation in the README file there) (2016-03-29). - * arch/arm/src/armv7-m and stm32: Add support for the IAR toolchain for - the limited case of the ARMv7-M architecture and the STM32 chip. From - Aleksandr Vyhovanec (2016-04-02). - * arch/arm/src/stm32/stm32f40xxx_rtc.c: Add a custom RTC driver. From - Neil Hancock (2016-04-02). - * include/nuttx/timer/rtc.h and drivers/timers/rtc.c: Simplify the RTC - interface.

From - Kha Vo (2016-04-08). - * libc/signal and include/signal.h: Rename sigset() to signal(). - sigset() is the System V function; signal() is the obsoleted POSIX - name. These seem to be equivalent. Neither are relevant in modern - POSIX programming but the name signal() probably has the better - credentials. sigset() is now relegated to a #define in signal.h that - makes it equivalent to signal() (2016-04-10). - * configs/nucleus2g: Removed the Nucleus2G configuration. There has - not been any activity with the commercial board in a few years and it - no longer appears to be available from the 2g-eng.com website. - Since the board is commercial and no longer publicly available, it - no longer qualifies for inclusion in the open source repositories. - The code as of this data is still available in the Obsoleted - repository at configs/nucleus2g (2016-04-12). - * arch/arm/src/stm32l4: Fix the STM32L4 SPI driver. That SPI driver is - quite different. They now handle frames of arbitrary size between 4 - and 16 bits. It was broken before a new bit has to be set (RX fifo - threshold) to handle <= 8-bit transactions. If not set, the default is - 16-bit packed >=8-bit frames and the RXNE bit is never set (it is set - when 16-bits are received). weird things as always. - This also add 8-bit access routines to the data register, because a - 16-bit access to the data register when the frame size is below 9 bits - is interpreted as a packed dual frame exchange. Sebastien Lorquet - (2016-04-13). - * net/sockets/listen.c and accept.c and include/nuttx/net: Separate - out psock_listen() and psock_accept() for internal OS usage - (2016-04-14). - * fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are - no longer allocated for kernel threads. They must use SYSLOG for - output and the low-level psock interfaces for network I/O. This - saves a little memory which might be important for small footprint - configurations (2015-04-14). - * Framebuffer driver: Add a display number to each interface in order - to support multiple display devices (2015-04-14). - * drivers/wireless/nrf24l01.c: Fix backward calculation of relative - frequency.

There are know outstanding SMP issues as noted in the - Sabre-6Quad README.txt file (2016-05-22). - * configs/sabre-6quad: Add an SMP configuration; Enable procfs in all - configurations (2016-05-22). - * include/nuttx/crypto/aes.h: Modifications to the crypto API needed - for LPC43xx. From Alexander Vasiljev (2016-05-23). - * arch/arm/src/lpc43xx: Add AES support. From Alexander Vasiljev - (2016-05-24). - * configs/*/src/tiva_timer.c: Tiva boards: Fix a naming collision, - rename board-specific function from tiva_timer_initialize() to - tiva_timer_configure() to remove conflict (2016-05-23). - * arch/arm/src/sam*: Ensure that the TWIHS (i2c) hw get's its clock - set when the sequence of sam_i2cbus_initialize(), - sam_i2cbus_uninitialize(), then sam_i2cbus_initialize() or twi_reset() - is called. I found this a while back in the stm32 family, so there - may be more arch-es with this sort of bug. I suppose any driver that - has the notion of "do not set the freq if it is already set" could be - suspect. From David Sidrane (2016-05-23). - * arch/arm/src/samv7: Add the up_systemreset interface to the samv7 - arch. The approach is slightly different in that: 1) It enables - ARCH_HAVE_RESET and allows the user to set if, and for how long, to - drive External nRST signal. It also does not contain a default - board_reset, as that really should be done in the config's src if - CONFIG_BOARDCTL_RESET is defined. From David Sidrane (2016-05-23). - * arch/arm/include/lpc43xx and src/lpc43xx: Adds definitions for the - LPC4337jet100 chip. From Alexander Vasiljev (2016-05-24). - * Many files: board_app_initialize() now accepts an argument that may - be used to support initialization in different configurations - (2016-05-24). - * arch/arm/src/samv7: Remove disabling of whole USB on suspend of USBHS. - This fix removes the disabling of the whole USB peripheral on suspend - interrupt. Its enough to freeze the clock instead. When disabling the - whole peripheral, the next wakeup-interrupt comes up with an disabled - clocking. The unfreeze clock has no effect, because the master clock - is disabled. This makes all registers, including the IDR unwriteable - and the IRQ falls in an endless loop blocking the whole system. - Furthermore the disabling of the peripheral clock prevents hotplugging - or reconnecting the USB. From Frank Benkert (2015-05-25). - * drivers/lcd: Add support for PCF8574 LCD Backpack driver. This driver - supports an interface board that is based on the PCF8574 io expander - and supports the HD44780-based (or compatible) LCD modules. There - are a myriad of different vendors of such, but they are principally - the same, save wiring and minor features like jumpers for I2C - addresses. This driver supports known and unknown variants. From - Dave (ziggurat29, 2013-6-26). - * arch/arm/stm32: Add support for a custom 1-wire driver. The serial - driver already supports a 1-wire interface, but this driver uses the - same serial logic to implement a lower half driver much like the I2C - lower half driver. From Aleksandr Vyhovanec (2015-05-25). - * fs/: Add logic to detach a file structure from a file descriptor. - This is for use only within the OS. It permits an open file or driver - to be used across multiple threads (2016-05-26). - * arch/arm/src/stm32l4: Get I2C working for STM32L4. From Dave - (ziggurat29) (2016-05-25). - * fs/ and include/nuttx/fs: Add logic to detach a file structure from a - file descriptor. This is for use only within the OS. It permits an - open file or driver to be used across multiple threads. (2016-05-26). - * drivers/analog/adc.c, include/nuttx/analog/adc.h, and all ADC lower - half drivers: No longer uses global adc_receive() call. Added a new - bind() method to the ADC interface. Now the ADC upper half driver - will register its receipt-of-data callback. This change allows the - ADC lower half driver to be used with a differ ADC upper half - (2016-05-26). - * drivers/analog/ads1255.c: Must not do SPI access from interrupt - handler. Use the worker thread instead. Must also lock the SPI bus - before using it. (2015-05-26). - * drivers/: Several SPI-based drivers modified. All drivers that use - SPI must call SPI_LOCK and SPI_UNLOCK. This is not optional - (2016-05-26). - * drivers/sensors: Fix a bug in crc computation for ms583730. - Implement POSIX read (2016-05-27). - * arch/arm/src/samv7: This is a fix to a problem in the handling of the - oneshot timer. Due to a wrong assumption concerning the behavior - directly after the start of the timer/counter the function - sam_oneshot_cancel(…) calculates the wrong remaining time. The code - assumes that the counter register is zero directly after the start of - the timer, but this is not true. To start the time/counter a software - trigger is invoked, this trigger starts the timer/count and sets the - counter register to zero, but the reset of the counter register is not - performed instantly. According to the datasheet: "The counter can be - reset by a trigger. In this case, the counter value passes to zero on - the next valid edge of the selected clock." Thus the counter is set to - zero between 0 and USEC_PER_TICK microseconds after the clock was - started. - In my fix I use the freerun count value to determine if at least one - tick passed since the start of the timer and thus if the value of the - oneshot counter is correct. I also tried to use the function - up_timer_gettime(…) to achieve this but, at least if compiled with no - optimization the problem vanishes without using the value of the - function, the function call takes too long. - Another problem treated in the fix is that if the oneshot timer/counter - is canceled, we only know the remaining time with a precision of - USEC_PER_TICK microseconds. This means the calculated remaining time - is between 0 and USEC_PER_TICK microseconds too long. To fix this I - subtract one tick if the calculated remaining time is greater than one - tick and otherwise set the remaining time to zero. By doing so the - measured times are much more precise as without it. From Stefan Kolb - (2016-05-27). - * arch/arm/src/sama5: Stefan Kolb's change to the SAMV7 Oneshot Timer - should also be applied to the SAMA5 oneshot time since the drivers are - identical (2016-05-27). - * arch/arm/src/stm32l4: Add support for SPI 4 and 5 on stm32f411 chips. - From Konstantin Berezenko (2016-05-27). - * arch/arm/src/sam34: Stefan Kolb's change to the SAMV7 Oneshot Timer - should also be applied to the SAM3/4 oneshot time since the drivers - are identical (2016-05-29). - * arch/arm/src/stm32: Allow to not use all channel in a lower part of - PWM. From Pierre-noel Bouteville (2016-05-30). - * libc/math: Add a NAN test on 'x' in asin function of lib_asin.c. - Suggested by Pierre-noel Bouteville (2016-05-31). - * arch/arm/src/stm32: Fix logic in F4 RTCC driver that prevent ALARM - interrupt.

From Frank Benkert (2016-06-01). - -7.17 2016-07-25 Gregory Nutt - - * drivers/mtd/flash_eraseall.c: Removed. This is no longer used - in the OS and is simply a wrapper around the MDIOC_BULKERASE - IOCTL command. It used to be called (only) from - apps/system/flash_eraseall, but that has been removed because it - violated the OS/application interface -- by calling flash_eraseall(). - The old code can be found in the Obsoleted' repository (and a revised - version can be found at apps/fsutils/flash_eraseall) (2016-06-03). - * arch/arm/src/stm32: STM32 Timer Driver: Change calculation of per- - timer pre-scaler value.

From v01d - (phreakuencies) (2016-06-04) - * arch/arm/src/kl and lpc11xx: rename xyz_lowputc to up_putc. Remove - all references to up_lowputc, everywhere (2016-06-04). - * configs/stm32f103-minimum: Add minnsh configuration. From Alan - Carvalho de Assis (2016-06-04). - * arch/arm/src/stm32: Add the up_getc() function to STM32 in order to - support the minnsh configuration. From Alan Carvalho de Assis - (2016-06-04). - * include/sys/boardctl.h: Needs to be usable with C++ files (2016-06-05). - * tools/tesbuild.sh will now build NxWM configurations (2016-06-05). - * arch/arm/src/stm32: In PWM driver, just update duty if frequency is - not changed and PSM started. This removeis glitch or blinking when - only duty is frequently changed. From Pierre-noel Bouteville (2016-06-05). - * arch/arm/src/kinetis: Add a USB device controller driver. Derived from - the pic32mx usb driver, which uses the same usb controller. From kfazz - (2016-06). - * configs/teensy-3.x: Add USB support and a usbnsh configuration. From - kfazz (2016-06). - * arch/arm/src/stm32: Add support for the STM32F105R. From Konstantin - Berezenko (2016-06-06). - * include/signal.h: Change type of SIG_ERR, SIG_IGN, ... to - _sa_handler_t. The type void does not work with the IAR toolchain. - From Aleksandr Vyhovanec (2016-06-07). - * configs/nucleo-144: Refactored configs/nucleo-144 sub-directories to - support additional nucleo-144 board. Add support for the Nucleo-F767ZI - board. From David Sidrane (2016-06-07). - * arch/arm/src/stm32f7 and include/stm32f7: Added STM32F76xxx and - STM32F77xx families. From David Sidrane (2016-06-08). - * Refactoring configs/nucleo-144 sub-directories to support additional - nucleo-144 board. Add support for the Nucleo-F767ZI board. From David - Sidrane (2016-06-08). - * include/assert.h: Check if NDEBUG is defined. From Paul Alexander - Patience (2016-06-08). - * arch/arm/src/stm32: Fix STM32 DMA code and configuration for STM32F37X - chips. From Marten Svanfeldt (2016-06-08). - * drivers/mtd: Add a driver of IS25xP SPI flash devices. From Marten - Svanfeldt (2016-06-09). - * arch/arm/src/Kconfig and configs/teensy-3.x: Teensy clock fixes. The - High Gain bit in MCG_C1 was preventing teensy from booting except - after a programming session. The second change doesn't appear to - change any functionality, but complies with restrictions in the k20 - family reference manual on FEI -> FBE clock transiions. From kfazz - (2016-06-09). - * configs/*/include/board.h: Fix timer input clock definitions. From - David Sidrane (2016-06-09). - * Networking: In both IPv6 and IPv4 incoming logic: (1) Should check - if the packet size is large enough before trying to access the packet - length in the IP header. (2) In the comparison between the IP length - and the full packet length, need to subtract the size of the link - layer header before making the comparison or we will get false - positives (i.e., the packet is really too small) (2016-06-09) - * configs/: All configurations that have both CONFIG_NSH_LIBRARY=y and - CONFIG_NET=y must now also have CONFIG_NSH_NETINIT=y (2016-06-09). - * arch/arm/src/kinetis: Kinetis pwm support, based on kl_pwm driver. - From kfazz (2016-06-09). - * arch/srm/src/stm32: Fix compilation errors in debug mode of - stm32_pwm.c. From Konstantin Berezenko (2016-06-09). - * arch/arm/src/kinetis: Support up to 8 channels per timer. From kfazz - (2016-06-09). - * lib/: crc16: Fix error. From Paul Alexander Patience (2016-06-10). - * lib/: Add crc64 support. From Paul Alexander Patience (2016-06-10). - * arch/arm/src/kinetis: Added kl_dumpgpio functionality as - kinetis_pindump. From kfazz (2016-06-10). - * arch/arm/src/sam34: Fix some errors in AFEC header file. From - OrbitalFox (2016-06-10). - * arch/arm/include/stm32: Correct the can2 rx irq number for stm32f10xx - chips. From Konstantin Berezenko (2016-06-10). - * drivers/include/input: Button upper half driver: Add definitions - needed for compilation with the poll() interface is not disabled - (2016-06-11). - * Kconfig/, include/debug.h, and many other files: (1) Debug features - are now enabled separately from debug output. CONFIG_DEBUG is gone. - It is replaced with CONFIG_DEBUG_FEATURES. (2) The macros dbg() and - vdbg() have renamed as err() and info(), respectively. This also - applies to all of the variants as well, lldbg(), llvdbg(), XXdbg(), - XXvdbg(), XXlldbg(), and XXllvdbg(). (3) Add a new debug level, - warn() (and all variants vwarn(), llwarn(), etc.). (4) Debug - assertions can now be enabled separately from debug output. (5) You - can now enable subsystem/device driver debug output at different - output levels. For example, CONFIG_DEBUG_FS no longer enables file - system debug output. It enables general file system debug logic and - enables selection of CONFIG_DEBUG_FS_ERROR, CONFIG_DEBUG_FS_WARN, - and CONFIG_DEBUG_FS_INFO (2016-06-12). - * strtoul() and strtoull(): Fix errno settings required by function - definition. Resolved Bitbucket Issue #1. From Sebastien Lorquet - (2016-06-13) - * arch/arm/src/stm32f7: Add SPI driver. DMA not yet supported. From - David Sidrane (2016-06-14). - * configs/nucleo-144: Add test for STM32 F7 SPI. From David Sidrane - (2016-06-14). - * alert(): New debug macro: alert(). This is high priority, - unconditional output and is used to simplify and stanardize crash - error reporting(2016-06-14). - * arch/arm/src/tiva: Bug Fix in tiva_serial.c - UART5, UART6 and UART7 - were not being configured as TTYS0 for printing over serial console. - From Shirshak Sengupta (2016-06-14). - * SAMV7: SPI: SPI-Freq. 40MHz; VARSELECT; hw-features - This change adds the following improvements: - - Increase the allowed SPI-Frequency from 20 to 40 MHz. - - Correct and rename the "VARSELECT" option - This option was included in the code as "CONFIG_SPI_VARSELECT" but - nowhere defined in a Kconfig file. The change renames it to - "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation - according the datasheet of Atmel. In short, this option switches - the processor from "fixed peripheral selection" (single device) to - "variable peripheral selection" (multiple devices on the bus). - - Add a new Function to the interface to control the timing and delays - of the chip according the ChipSelect lines. This function can - control the delay between the assertion of the ChipSelect and the - first bit, between the last bit and the de-assertion of the - ChipSelect and between two ChipSelects. This is needed to tune the - transfer according the specification of the connected devices. - - Add three "hw-features" for the SAMV7, which controls the behavior - of the ChipSelect: - - force CS inactive after transfer: this forces a (short) - de-assertion of the CS after a transfer, even if more data is - available in time - - force CS active after transfer: this forces the CS to stay active - after a transfer, even if the chip runs out of data. - Btw.: this is a prerequisit to make the LASTXFER bit working at all. - - escape LASTXFER: this suppresses the LASTXFER bit at the end of the - next transfer. The "escape"-Flag is reset automatically. - From Frank Benkert (2016-06-14) - * Many CONFIG_DEBUG_* options did not have matching macros defined in - include/debug.h. Rather, there were various definitions scattered - throughout the sourse tree. These were collected together and - centralized with single macro definitions in include/debug.h - (2016-06-15) - * STM32F7: Add SPI, I2C, and ADC drivers. From Lok Tep (2016-06-15). - * err(), warn(), info(), and alert() renamed to include leading '_'. - This was done to avoid some naming collisions (2-06-16 - * STM32: Move backup domain reset to earlier in the initialization - sequence (stm32_rcc.c() in order to avoid disabling LSE during RTC - initialization. From Alan Carvalho de Assis (2016-06-16). - * SYSLOG: syslog() will now automatically redirect output to lowsyslog() - if called from an interrupt handler (2016-06-16). - * STM32: When configuring a GPIO via stm32_configgpio() the function - will first set the mode to output and then set the initial state of - the gpio later on. If you have an application with an externaly - pulled-up pin, this would lead to a glitch on the line that may be - dangerous in some applications (e.G. Reset Line for other chips, - etc). This changes sets the output state before configuring the pin - as an output. From Pascal Speck (2016-06-17). - * STM32 F7: Apply Pascal Speck's GPIO STM32 change to STM32 L4 - (2016-06-17). - * STM32 L4: Apply Pascal Speck's GPIO STM32 change to STM32 L4. - From Sebastien Lorquet (2016-06-17). - * Review all uses of *err(). These macro family should indicate only - error conditions. Convert *err() to either *info() or add ERROR:, - depending on if an error is reported (2016-06-17). - * STM32F7: Review, correct, and update I2C, SPI, and ADC drivers. From - David Sidrane (2016-06-17). - * LPC17 Ethernet: Needs to correctly ignore PHYID2 revision number - when comparing PHY IDs (2016-06-18). - * SYSLOG: Consolidate all SYSLOG logic in drivers/syslog. Add an - abstraction layer that supports: (1) redirection of SYSLOG outpout. - This is usually so that you can boot with one SYSLOG output but - transition to another SYSLOG output when the OS has initialialized, - (2) adds common serialization of interrupt output as a configuration - option. Without this configuration setting, interrupt level output - will be asynchronous. And (3) vsyslog is now a system call and is - usable with other-than-FLAT builds (2016-06-19). - * TCP Networking: While working with version 7.10 I discovered a - problem in TCP stack that could be observed on high network load. - Generally speaking, the problem is that RST flag is set in - unnecessary case, in which between loss of some TCP packet and its - proper retransmission, another packets had been successfully sent. - The scenario is as follows: NuttX did not receive ACK for some - sent packet, so it has been probably lost somewhere. But before - its retransmission starts, NuttX is correctly issuing next TCP - packets, with sequence numbers increasing properly. When the - retransmission of previously lost packet finally succeeds, tcp_input - receives the accumulated ACK value, which acknowledges also the - packets sent in the meantime (i.e. between unsuccessful sending of - lost packet and its proper retransmission). However, variable unackseq - is still set to conn->isn + conn->sent, which is truth only if no - further packets transmission occurred in the meantime. Because of - incorrect (in such specific case) unackseq value, few lines further - condition if (ackseq <= unackseq)is not met, and, as a result, we - are going to reset label. From Jakub Łągwa (2016-06-20). - * SYSLOG: Remove lowsyslog(), vlowsyslog(), and associated macros - *llinfo(), *llwarn(), and llerr(). In the redesigned syslog() logic, - these serve no purpose (2016-06-20). - * Make system: Need to build the drivers/ directory even it file - descriptors are not supported. There are things in the drivers/ - directory that are still needed (like SYSLOG logic) (2016-06-20). - * assert.h: Define static assert for C++ usage. From Paul Alexander - Patience (2016-06-21). - * arch/arm/src/stm32l4: Add ioctls to set/get bit timing in stm32l4. - Add ioctl hooks to allow future management of can id filters. From - Sebastien Lorquet (2016-06-21). - * drivers/can.c: Add support for poll. From Paul Alexander Patience - (2016-06-21). - * drivers/syslog: Extend SYSLOG logic so that we can send SYSLOG output - to a file. Not verified on initial commit (2016-06-21). - * arch/arm/src/stm32l4: Add some CAN mode IOCTL calls. These will be - useful for device autotest when the application boots. They are - redundant with the CONFIG_CAN_LOOPBACK option, which can now just be - interpreted as a default setting. From Sebastien Lorquet (2016-06-22). - * drivers/syslog: syslog_dev_flush() needs to check if the inode is a - mountpoint before calling the flush() method. Noted by David Sidrane - (2016-06-22). - * arch/arm/src/stm32f7: Adds SDMMC1 for stm32F7 74-75. From Lok Tep - (2016-06-22). - * drivers/syslog: SYSLOG character device channel will now expand LF to - CR-LF. Controllable with a configuration option (2016-06-22). - * arch/arm/src/stm32l4: Implementation of loopback IOCTLs. From - Sebastien Lorquet (2016-06-22). - * Documentation: Add SYSLOG documentation to the porting guide - (2016-06-22). - * configs/stm32f746g-disco: Removed knsh configuration it failed to - refresh (via tools/refresh.sh). I assume that it is a hand-edited - configuration and, hence, must be removed from the repository - (2016-06-23). - * arch/arm/arc/sam34: DAC bugfix: DACC_WPMR_WPKEY_MASK -> DACC_WPMR_WPKEY. - Timer bugfix: Fix ops check in TCIOC_STOP. From Wolfgang Reissnegge - (2016-06-23). - * configs/nucleo-144: Added SDMMC support to Nucleo-144. From David - Sidrane (2016-06-23). - * arch/arm/src/stm32: Port STM32L4 CAN IOCTLs to STM32. From Sebastien - Lorquet (2016-06-24). - * drivers/ioexpander: Add support for a very simple GPIO driver. It - supports only pre-conrigured input and output pins and only basic - input and output operations (2016-06-24). - * arch/arm/src/lpc43xx: Correct auto-negotiation mode in the LPC43xx - Ethernet. From Alexander Vasiljev (2016-06-24) - * arch/arm/src/samv7: TWIHS Driver improved and GPIO-Driver fixed for - Open-Drain Pins - - sam_gpioread: Now the actual line level from the pin is read back. - This is extremely important for Open-Drain Pins, which can be used - bidirectionally - - Re-Implemented twi_reset-function and enhanced it so it can be - called from inside the driver (see next point) - - Glitch-Filter: Added a configuration option to enable the twi-built- - in glitch filter - - Added a "Single Master Mode": In EMC Testing the TWI-Bus got stuck - because the TWI-Master detected a Multi-Master access (but there is - no second master). With the option "Single Master" we detect these - events and automatically trigger a twi_reset. We also do an - automatic recovery if a slave got stuck (SDA stays low). - With the above changes I²C-Bus reliability in harsh environments (eg. - EMC) is greatly improved. The small change in the GPIO-Driver was - necessary because otherwise you cannot read back the correct line - status of Open-Drain Outputs and this is needed by the twi_reset - function. From Michael Spahlinger (2016-06-24) - * arch/arm/src/stm32f7: BUGFIX:PLLs IS2 and SAI P Calculation. From - David Sidrane (2016-06-24). - * arch/arm/src/stm32f7: USB support. From Lok Tep (2016-06-27). - * configs/olimex-stm32-e407: Add support for Olimex STM32 E407 - board. From Mateusz Szafoni (2016-06-27). - * drivers/ioexpander: Shadow-Mode: The output- and configuration - registers of the IO-Expander are held in the microcontrollers memory - and only written to the IO-Expander. This reduces bus traffic and - is more error-proof than the normal read-modify-write operation. Retry - Mode: If enabled and an error occurs while writing to the IO-Expander - the current transmission is automatically repeated once. From Michael - Spahlinger (2016-06-27). - * libc/hex2bin: Move the portable library portion of apps/system/hex2bin - to nuttx/libc/hex2bin where it can be shared with the OS internals - (2016-06-27). - * configs/nucleo-144: Added USB OTG device to Nucleo-144.

From David - Sidrane (2016-06-27). - * arch/arm/src/stm32f7: Added PWR, RTC, and BBSRAM support for stm32f7. - From David Sidrane (2016-06-27). - * Build system: Fixed build of SAMV71-XULT/nsh. With the changes from - 26f7b8c the build process of the default configuration did not succeed - anymore. From Michael Spahlinger (2016-06-28). - * sched/semaphore: Need to set errno to EINVAL on errors in sem_post() - and sem_wait(). From Paul Alexander Patience (2016-06-28). - * Build system: This change fixes a build problem that only occurs when - reconfiguring from Linux to Windows or vice-versa. It is a problem - that was present but not usually experienced until two things happened: - (1) The pre_config target was added to run before the menconfig - operation and (2) the context target was added before the pre_config - target in order to set up the correct symbolic links (in the apps/platform - directory) needed by the pre_config target. - But then now if you start with a Linux system and run 'make menuconfig' - to switch to Linux, the context target will execute first and set up - POSIX style symbolic links before doing the menuconfig. Then after the - menuconfig, the make will fail on Windows if you are using a Windows - native toolchain because that native toolchain cannot follow the Cygwin- - style symbolic links. - The fix here is to also execute the clean_context AFTER executing - menuconfig. A lot more happens now: It used to be that doing 'make - menuconfig' only did the menuconfig operation. Now it does context, - pre_config, menuconfig, clean_context. Not nearly as snappy as it used - to be (2016-06-28). - * arch/arm/src/efm32, lcp43, stm32, stm32l4: disable interrupts with - NVIC_IRQ_CLEAR. From Paul Alexander Patience (2016-06-28). - * arch/arm/src/stm32f7: STMF7xxx RTC: (1) Remove proxy #defines, (2) - Ensure the LSE(ON) etal are set and remembered in a) A cold start - (RTC_MAGIC invalid) of the RTC, and b) A warm start (RTC_MAGIC valid) - of the RTC but a clock change. The change was needed because in bench - testing a merge of the latest's STM32 53ec3ca (and friends) it became - apparent that the sequence of operation is wrong in the reset of the - Backup Domain in the RCC code. PWR is required before the Backup - Domain can be futzed with. !!!This Code should be tested on STM32 and - if needed rippled to the STM32 families. From David Sidrane - (2016-06-28). - * arch/arm/src/stm32f7: Added STMF7xxx RTC. From David Sidrane - (2016-06-28). - * arch/arm/src/stm32: STM32 BBSRAM fixed (and formatted) flags. From - David Sidrane (2016-06-28). - * arch/arm/src/stm32f7: STM32F7 BBSRAM fixed (and formatted) flags. - From David Sidrane (2016-06-28). - * arch/arm/src/stm32f7: Added STM32F7 DBGMCU. From David Sidrane - (2016-06-28). - * arch/arm/src/samv7: SAMV7: CAN Message Filtering fixed: (1) stdfilters - didn't work because the filter was never enabled (wrong number of bits - to shift), and (2) Filters were never used because the configuration - register cannot be written without using the initialization mode. - Both bugs are fixed by this change. Filtering has been tested with - both standard and extended identifiers and is now working properly. - From Michael Spahlinger (2016-06-29). - * configs/Kconfig and dummy/: Add logic to support custom board - directories that include a Kconfig file. During the context phase - of the build, any Kconfig file in the custom board directory is copied - into configs/dummy, replacing the existing Kconfig file with the - target Kconfig file (2016-06-29). - * arch/arm/src/stm32l4: Port support for both RX FIFOs from STM32 CAN. - From Paul Alexander Patience (2016-06-29). - * Remove all inclusion of header files from the apps/include directory. - This caused a lot of reshuffling of logic: binfmt pcode support, - usbmonitor is now a kernel thread, TZ/Olson database moved to - libc/zoneinfo (2016-06-29). - * drivers/mtd: Several MTD FLASH drivers nullify the freed 'priv' - structure and failed to return NULL as stated in the comments. - Result, will operate on a NULL pointer later. Noted by David Sidrane - (2016-06-30). - * arch/arm/src/kinetis: Add basic support for the K64 family. I - leveraged the changes from https://github.com/jmacintyre/nuttx-k64f - and merged into the existing kinetis code with a lot of changes and - additions (like pin multiplexing definitions). (2016-07-01). - * configs/freedom-k64f: Add support for the NXP Freedom-K64F board. - This is primarily the work of Jordan Macintyre. I leveraged this - code from https://github.com/jmacintyre/nuttx-k64f but with - significant corrections (LEDs, buttons, README, etc) and extensions - and updates to match more recent BSPs (2016-07-01). - * libc/signal: Add raise() (2016-07-04). - * drivers/syslog: Add a SYSLOG character device that can be used to re- - direct output to the SYSLOG (2016-07-05). - * net/netdev: Break out internal interface psock_ioctl() (2016-07-06). - * configs/stm32f4disovery: Add can driver for stm32f4discovery. From - Matthias Renner (2016-07-06). - * configs/freedom-k64f: Increase MCU clock to 120MHz (2016-07-06). - * arch/arm/src/stm32: Add support for Tickless mode (two timer - implementation). From Max Neklyudov (2016-07-06). - * drivers/usbdev: cdcacm_unbind leaks write request objects. This - arises due to freeing the bulk IN endpoint before the loop that - frees the requests via cdcasm_freereq. That function checks the - parameters and skips the freeing if either is NULL. Freeing the bulk - IN enpoint will cause the first param to be NULL, thereby bypassing - the free operation. To fix, I moved the release of the bulk IN - endpoint until after to loop (much as was the case for the OUT and - read requests, which did not exhibit the problem). From ziggurat29 - (2016-07-07). - * arch/arm/src/stm32l4: Update usb dev/host controller drivers to - reflect new(ish) logging standards; augment device enpoint and fifo - allocation #defines to do more sanity checking, and be automatically - adaptive to size changes. Update README.txt to reflect current status - of the implementation. From ziggurat29 (2016-07-07). - * arch/arm/src/stm32f7: Fixed STM32F7 DMA stm32_dmacapable. DMA working - on SDMMC. From David Sidrane (2016-07-07). - * configs/stm32f4discovery: add configuration files for canard. From - Matthias Renner (2016-07-08). - * drivers/pipe: Add missing configuration for pipe ring buffer size. - From Frank Benkert (2016-07-08). - * STM32L4: Fix incorrect clock setup for LPTIM1. From ziggurat29 - (2016-07-08). - * nucleo-l476rg and stm32lf76vg-disco: Define timer clock frequencies on - STM32L4-based boards. From ziggurat29 (2016-07-08). - * STM32L4: Add support for tickless OS, and incidentally timers, pwm, - oneshot, free-running.... From ziggurat29 (2016-07-08). - * SAM3/4 I2C: Fix reversed logic in twi_startmessage(). From Wolfgang - Reissnegger (2016-07-09). - * VFS ioctl(). Per comments from David Sidrane, file_ioctl() should not - return succeed if the ioctl method is not supported. It probably - should return ENOTTY in that case (2016-07-09). - * libm: This change should significantly improve the performance of - single precision floating point math library functions. The vast - majority of changes have to do with preventing the compiler from - needlessly promoting floats to doubles, performing the calculation - with doubles, only to demote the result to float. These changes only - affect the math lib functions that return float. From David Alessio - (2016-07-11). - * STM32F4 Discovery: Add FPU support for ostest for the STM32F4Discovery - platform. From David Alessio (2016-07-11). - * Build system: Remove the includes/apps link to apps/include. It is - no longer used. From Sebastien Lorquet (2016-07-11). - * printf(): If there are no streams, let printf() fall back to use - syslog() for output (2016-07-11). - * Qemu-i486: Fix qemu-i486/ostest/Make.defs test for M32. From Heath - Petersen (2016-07-12). - * UART 16550: Handle when CONFIG_SERIAL_UART_ARCH_IOCTL is not enabled. - From Heath Petersen (2016-07-12). - * Kinetis Ethernet: Add support for the KSZ8081 PHY (2016-07-12). - * SST26 Driver: Before accessing the sst26 flash, the "Global Unlock" - command must me executed, which I do in the sst26 driver. BUT re- - reading the datasheet, the WREN instruction is required to enable the - execution of this command. This was not done. I have no idea how the - driver currently works except by chance. The writes should never - happen at all, the flash is half-enabled! From Sebastien Lorquet - (2016-07-12). - * Freedom K64F: Add a networking NSH configuration. (2016-07-12). - * N25Qxx Driver: Alter the notion of 'blocksize' to be equivalent to - 'flash write page size' in order to align with assumptions in the - smartfs driver (at least, maybe other things do as well). Correct a - bug that was previously masked by having blocksize=eraseblocksize - which would cause buffer overflows and delicious hardfaults. Trivial - spelling changes in comments, etc. From ziggurat29 (2016-07-12). - * STM32L476 Discovery: Update stm32l476 disco to include init code for - smartfs and nxffs for cases where those fs are included in build. - From ziggurat29 (2016-07-12). - * Kinetis Ethernet and Freedom-K64F: Freedcom-K64F PHY address was - wrong. Modified Ethernet driver to try all PHY addresses and then - only fail if the driver cannot find a usable PHY address. MDIO pin - must have an internal pull-up on the Freedom-K64F (2016-07-12). - * Kinetis Ethernet: Add support for CONFIG_NET_NOINTS (2016-07-12). - * SmartFS: Fix a 32-byte memory leak. From Ken Pettit (2016-07-12). - * Freedom-K64F: SDHC is now enabled in the nsh configuration (but does - not work)Add hooks for automounter; Change NSH configuration to use - Windows (2016-07-13). - * SAMV7 USBHS Device: This change solves a problem which causes data - loss while sending data via USB. This problem is caused by an incorrect - handling of the endpoint state in the USB driver sam_usbdevhs. This - leads under some circumstances to situations in which an DMA transfer - is setup while a previous DMA transfer is currently active. Amongst - other things I introduced the new endpoint state USBHS_EPSTATE_SENDING_DMA - for the fix. To reproduce the problem, I used a program which send as - many data as possible via a CDC/ACM device and verified the received - data on the PC. From Stefan Kolb (2016-07-13). - * STM32: Fix bug in oneshot timer. From Max Neklyudov (2016-07-13). - * STM32L4: Port foward bugfix from stm32 of oneshot timer. From - ziggurat29 (2016-07-13). - * STM32 and EFM32: I'm using syslog through ITM. In this case - syslog_channel function is call before RAM initialization in - stm32_clockconfig. But syslog channel uses a global variable that is - reset to default by the RAM initialization. From Pierre-noel - Bouteville (2016-07-14). - * LPC43xx SPIFI: If CONFIG_SPIFI_SECTOR512 undefined, lpc43_bwrite - doesn't do actual write (probably copy/paste errors). Still not sure - about current state of lpc43_spifi implementation, but for me NXFFS - works with this patch. From Vytautas Lukenskas (2016-07-14). - * SMART MTD layer: Fixes freesector logic error when sectorsPerBlk=256, - adds DEBUGASSERT for invalid geometry and additional memory debug - logic. Also fixes the dangling pointer on error bug. From Ken - Pettit (2016-07-14). - * arch/arm/src/lpc43xx: Extend LPC43xx EMC code to support SDRAM on a - dynamic memory interface. From Vytautas Lukenskas (2016-07-19). - * arch/sim/src: Add the simulated QSPI (N25Q) flash to the simulation - and modify sim up_spiflash.c to enable it to run with different MTD - drivers based on config options (currently m25p, sst26 and w25). - From Ken Pettit (2016-07-19). - * drivers/pipe: Add support to allocating different sizes for pipe and - fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo() - and pipe(), but allow control of the size of the underlying, in-memory - circular buffer . Move pipe() and mkpipe() to nuttx/libc, they are no - longer core OS interfaces. Capability currenty used only by PTY logic - to support, configurable, smaller buffers for PTYs (2016-07-19). - * include/nuttx/drivers: Move driver-related files from include/nuttx - to include/nuttx/drivers. Move driver related prototypes out of - include/nuttx/fs/fs.h and into new include/drivers/drivers.h - (2016-07-20). - * include /nuttx/lib: Move library-related files from include/nuttx to - include/nuttx/lib (2016-07-21). - * drivers/serial/serial.c: Fix a race condition noted by Stefan Kolb. - Between the test if the TX buffer is full and entering a critical - section, bytes may be removed from the TX buffer making the wait - unnecessary. The unnecessary wait is an inefficiency, but not really - a problem. But with USB CDC/ACM it can be a problem because the - entire TX buffer may be emptied when we lose the race. If that - happens that uart_putxmitchar() can hang waiting for data to be - removed from an empty TX buffer (2016-07-22). - * arch/arm/src/stm32 and stm32l4: STM32 F4/L4 RTC ALARM: were enabling - interrupts too early in the power-up sequence, BEFORE the interrupt - system was being initialized (2016-07-23). - * drivers/ioexpander: GPIO driver: Add support for receiving signals - from interrupt pins (2016-07-23). - * drivers/usbdev: USBMSC: Add locks when removing request from queue. - From Wolfgang Reissnegger (2016-07-23). - * drivers/usbdev: USBMSC: Fix reversed logic on waiting for SCSI thread - start. The scsi thread was waiting for the wrong condition. However, - this was masked by the fact that the code creating the scsi thread was - also holding usbmsc_scsi_lock(priv) while initializing data, hence - this lock synchronized the scsi thread start with init completion. - From Wolfgang Reissnegger (2016-07-23). - * arch/arm/src/sam34: SAM3/4 UDP: Fix handling of endpoint RX FIFO - banks. This fixes a race condition where the HW fills a FIFO bank - while the SW is busy, resulting in out of sequence USB packets - (2016-07-23). - * Freedom-K64F: Add PWM support. From Jordan MacIntyre (2016-07-25). - -7.18 2016-10-08 Gregory Nutt - - * drivers/serial/pty.c, serial.c, usbdev/cdcacm.c, include/nuttx/fs/ioctl.h: - Fix FIONWRITE and add FIONSPACE. All implementations of FIONWRITE - were wrong. FIONWRITE should return the number of bytes waiting in - the outgoing send queue, not the free space. Rather, FIONSPACE should - return the free space in the send queue (2016-07-25). - * lib_dumpbuffer: Now prints a large on-stack buffer first to avoid - problems when the syslog output is prefixed with time. From Pierre- - noel Bouteville (2016-07-27). - * sched/clock and sched/sched: Add standard adjtime() interface and - basic timekeeping support. Normally used with an NTP client to keep - system time in synchronizationi. From Max Neklyudov (Merged on - 20160-07-28). - * arch/arm/src/stm32: Add timekeeping support for the STM32 tickless - mode. From Max Neklyudov (Merged on 20160-07-28). - * Top-Level Makefiles. Fix a chicken-and-egg problem. In the menuconfig - target, the context dependency was executed before kconfig-mconf. - That was necessary because the link at apps/platform/board needed to - be set up before creating the apps/Kconfig file. Otherwise, the - platform Kconfig files would not be included. But this introduces - the chicken-and-egg problem in some configurations. - In particular: (1) An NX graphics configuration is used that requires - auto-generation of source files using cpp, (2) the configuration is - set for Linux, but (3) we are running under Cygwin with (4) a Windows - native toolchain. In this case, POSIX-style symbolic links are set - up but the Windows native toolchain cannot follow them. - The reason we are running 'make menuconfig' is to change from Linux - to Cygwin, but the target fails. During the context phase, NX runs - CPP to generate source files but that fails because the Windows native - toolchain cannot follow the links. Checkmate. - This was fixed by changing all of the make menuconfig (and related) - targets. They no longer depend on context being run. Instead, they - depend only on the dirlinks target. The dirlinks target only sets - up the directory links but does not try to run all of the context - setup; the compiler is never invoked; no code is autogeneraed; and - things work (2016-07-28). - * tools/refresh.sh: Recent complexities added to apps/ means that - configuration needs correct Make.defs file in place in order to - configure properly (2016-07-28). - * tools/kconfig2html.c: Update to handle absolute paths when sourcing - Kconfig files (2016-07-29). - * libc/math: This fixes the following libc/math issues: (1) asin[f l]() - use Newton’s method to converge on a solution. But Newton’s method - converges very slowly (> 500,000 iterations) for values of x close - to 1.0; and, in the case of asinl(), sometimes fails to converge - (loops forever). The attached patch uses an trig identity for - values of x > sqrt(2). The resultant functions converge in no more - than 5 iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions - are based on Chebyshev fitting to a good guess. The problem there’s a - bug in the implementation that causes the functions to blow up with x - near -3.0. This patch fixes that problem. It should be noted that - this method returns the error function erf(x) with fractional error - less than 1.2E-07 and that’s fine for the float version erff(), but - the same method is used for double and long double version which - will yield only slightly better precision. This patch doesn't address - the issue of lower precision for erf() and erfl(). (3) a faster - version of copysignf() for floats is included. From David S. Alessio - (2016-07-30). - * I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h - definitons. Add support for an attach() method that may be used when - any subset of pin interrupts occur (2016-07-31). - * PCA9555 Driver: Replace the signalling logic with a simple callback - using the new definitons of ioexpander.h. This repartitioning of - functionality is necessary because (1) the I/O expander driver is the - lower-lower part of any driver that uses GPIOs (include the GPIO - driver itself) and should not be interacting directly with the much - higher level application layer. And (2) in order to be compatible - with the GPIO driver (and any arbitrary upper half driver), the - PCA9555 should not directly signal, but should call back into the - upper half. The upper half driver that interacts directly with the - application is the appropriate place to be generating signal - (2016-07-31). - * drivers/ioexpander/skeleton.c: Add a skeleton I/O Expander driver - (based on the PCA9555 driver) (2016-07-31). - * I/O Expander Interface: Encode and extend I/O expander options to - include interrupt configuration (2016-07-31). - * drivers/ioexpander: Add an (untested) TCA64XX I/O Expander driver - leveraged from Project Ara (2016-07-31). - * I/O Expander Interface: Add argument to interrupt callback. Add a - method to detach the interrupt (2016-08-01). - * drivers/ioexpander: Add a GPIO lower-half driver that can be used to - register a GPIO character driver for accessing pins on an I/O expander - (2016-08-01). - * drivers/ioexpander: Add PCF8574 I/O Expander driver. Some cleanup - also of other expander drivers (2016-08-01). - * drivers/ioexpander: GPIO driver: Add IOCTLs to get the pin type and - to unregister a signal handler (2016-08-01). - * configs/sim: Add simulator-based test support for apps/examples/gpio - 2016-08-01). - * drivers/sensors: Add KXTJ9 Accelerometer driver from the Motorola - Moto Z MDK (2016-08-02). - * arch/arm/sim: Add a simulated I/O Expander driver (2016-08-03). - * configs/sim: Add logic to set the simulated I/O expander for testing - with apps/examples/gpio (2016-08-03). - * fs/fat: FAT performance improvement. In large files, seeking to a - position from the beginning of the file can be very time consuming. - ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted time - since we are going to seek to the same position. This fix short- - circutes fat_seek() in all cases where we attempt to seek to current - position. Suggested by Nate Weibley (2016-08-03). - * tools/sethost.sh: Add sethost.sh. This is a script that you can use - to quickly change the host platform from Linux to Windows/Cygwin. - Might save you a lot of headaches (2016-08-03). - * arch/arm/src/tiva: Add tiva PWM lower-half driver implementation. - From Young (2016-08-05). - * drivers/spi/spi_transfer.c: Add a helper function that encapsulates - and manages a sequence of SPI transfers (2016-08-05). - * drivers/spi: Add an SPI character driver that will permit access to - the SPI bus for testing purposes. This driver is a simple wrapper - around spi_transfer() (2016-08-05). - * drivers/wireless: Add MFRC522 RFID ISO14443 and Mifare transceiver - driver. From Alan Carvalho de Assis (2016-08-06). - * configs/stm32f103-minimum: Add board support to MFRC522 driver. From - Alan Carvalho de Assis (2016-08-06). - * arch/renesas: Rename arch/sh to arch/renesas (2016-08-06). - * arch/arm/src/efm32, stm32, stm32l4: STM32 and EFM32 SPI drivers - adopted an incompatible conventions somewhere along the line. The - set the number of bits to negative when calling SPI_SETBITS which had - the magical side-effect of setting LSB first order of bit - transmission. This is not only a hokey way to pass control - information but is supported by no other SPI drivers. This change - three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. - (2) It changes the implementations of SPI_SETBITS in the STM32 and - EFM32 derivers so that negated bit numbers are simply errors and it - adds the SPI_HWFEATURES method that can set the LSB bit order, and - (3) It changes all calls with negative number of bits from all - drivers: The number of bits is now always positive and SPI_HWFEATURES - is called with HWFEAT_LSBFIRST to set the bit order (2016-08-08). - * arch/arm/src/stm32: Add missing SPI2 and SPI3 support for STM32F3F3. - Add STM32F37XX DMA channel configuration. For STM32F37XX, - SYSCFG_EXTICR_PORTE defined twice. From Alan Carvalho de Assis - (2016-08-08). - * arch/arm/src/stm32: Make stm32_pwr_enablebkp thread safe. From - Max Neklyudov (2016-08-09). - * arch/arm/src/stm32: SAM3/4 GPIO: Enable peripheral clock for GPIO port - when GPIO is configured as input. The value of a GPIO input is only - sampled when the peripheral clock for the port controller the GPIO - resides in is enabled. Therefore we need to enable the clock even when - polling a GPIO. From Wolfgang Reissnegger (2016-08-09). - * arch/arm/src/tiva: Fix two bugs of tiva pwm lower-half driver - implementation. From Young (2016-08-10). - * sched/group: Explicitly initialize the group tg_exitsem with - sem_init(). The existing logic worked because the correct - initialization value is all zero, but it is better to initialize the - semaphore explicitly (2016-08-10). - * arch/arm/stm32: Fix bad pllmul values for STM32F1XX connectivity line. - STM32F1XX connectivity line supports only x4, x5, x6, x7, x8, x9 and - x6.5 values. From Michał Łyszczek (2016-08-11). - * include/nuttx/timers: Add oneshot timer lower half interface - (2016-08-11). - * arch/arm/src/stm32: Add a experimental oneshot, lower-half driver for - STM32 (2016-08-11). - * arch/arm/src/samv7: Add option to support oneshot timer without free- - running timer. Add oneshot lower half driver (2016-08-11). - * arch/arm/src/sama5: Add option to support oneshot timer without free- - running timer. Add oneshot lower half driver (2016-08-11). - * arch/arm/src/sam34: SAM4CM: Add option to support oneshot timer without - free-running timer.

Was not - correctly handling negative integral value (2016-08-11). - * configs/sim: Add a configuration useful for testing Mini Basic - (2016-08-12). - * drivers/timers: Add an upper-half, oneshot timer character driver - (2016-08-12). - * arch/sim/src: Add a simulated oneshot lowerhalf driver (2016-08-12). - * arch/arm/src/stm32: STM32F3 SPI: Fix the number of bit setting for - the F3. That and data packing work differently on the STM32F3 than - for other STM32 parts (2016-08-12). - * arch/arm/stm32 and stm32l4: Enabling SPI DMA loses other bits in CR2 - (2016-08-13). - * arch/arm/src/stm32: STM32F3 SPI: Cannot write always 16-bit value to - DR register because of how the F3 implements data packing (2016-08-13). - * Kinetis: Add support for I2C and RTC. From v01d (phreakuencies) - (2016-08-13). - * teensy 3.x i2c.

From Konstantin Berezenko (2016-08-17). - * STM32 DMA Fix: Change stm32 adc dma callback to send channel number - instead of index. From Konstantin Berezenko (2016-08-17). - * SAMA5: Add missing oneshot max_delay method (2016-08-18). - * configs/stm32bufferfly2: Add support for the Kamami stm32butterfly2 - development board with optional ETH phy. From Michał Łyszczek - (2016-08-19). - * libc/misc: Separate XorShift128 PRNG from /dev/urandom and make it - generally available (2016-08-20). - * sched/sched_cpuload_oneshot: Use the oneshot timer with optional - entropy to measure cPU load if so configured (2016-08-20). - * drivers/usbhost/usbhost_composite.c: An an EXPERIMENTAL prototype of - how USB host support for composite devices might be implemented. This - feature is EXPERIMENTAL because (1) it is untested and (2) has some - know design issues that must be addressed before it can be of use - (2016-08-28). - * CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From Beat - Küng (2016-08-23). - * tools/mkfsdata.pl was still generating the old-style apps/include - inclusion paths (2016-08-23). - * drivers/sensors: Add drvier for the LIS3MDL 3 axis magnetometer.

From - Young (2016-09-26). - * LPC43xx Serial: There are some small problems in LPC43xx RS485 mode - configuration. In particular: (1) UART0,2,3 do not have DTR pins - (different from UART1), so, Kconfig needs to be adjusted. (2) - lpc43_uart.c in RS485 mode only configures DIR pin, but doesn't enable - pin output for UART0,2,3. (3) should be option to reverse DIR control - pin output polarity. (4) lpc43xx/chip/lpc43_uart.h doesn't have USART3 - definitions. NOTE: I didn't modified and didn't tested USART1, as it - has different hardware. From Vytautas Lukenskas. From Vytautas - Lukenskas (2016-09-30). - * STM32 Ethernet: Correct typo in conditional logic. From Neil Hancock - (2016-10-01). - * sched/pthread and task: When a pthread is started, there is a small - bit of logic that will run on the thread of execution of the new - pthread. In the case where the new pthread has a lower priority than - the parent thread, then this could cause both the parent thread and - the new pthread to be blocked at the priority of the lower priority - pthread (assuming that CONFIG_PRIORITY_INHERITANCE is not selected). - This change temporarily boosts the priority of the new pthread to at - least the priority of the new pthread to at least the priority of the - parent thread. When that bit of logic has executed on the thread of - execution of the new pthread, it will then drop to the correct - priority (if necessary) before calling into the new pthread's entry - point (2016-10-01). - * configs/stm32f103-minimum: Add stm32_bringup support and userled - example to STM32F103 Minimum board.

I will be making the FPGA code for - this available soon (within a week I would say). The board support on - this is pretty thin, but it seems like maybe a good idea to get the base - RISC-V stuff in since there are people interested in it. From Ken - Pettit (2016-10-16). - * C library: Add a dummy setlocale() function to avoid drawing the - function from newlib (2016-10-17). - * libc/wchar: Add wcslen, wmemchr, wmemcmp, wmemcpy and wmemset to NuttX. - From Alan Carvalho de Assis (2016-10-17). - * syscalls: Add setlocale to libc.csv (2016-10-17). - * libc/locale: Add clocale header file (2016-10-18). - * libc/wchar: Add functions btowc, mbrtowc, mbtowc, wcscmp, wcscoll, - wmemmove.

With CONFIG_LIBC_LOCALE - defined setlocale will act as if MB string is not supported and return - "C" for POSIX. C and "". From David Sidrane (2016-10-19). - * Xtensa ESP32: Add vectors for interrupt levels 2-6 (2016-10-20). - * strtof(): Add strtof() as simply a copy of strtod with types and - limits changed (2016-10-20). - * arch/arm/src/stm32v7: Register the watchdog device at the configured - device path CONFIG_WATCHDOG_DEVPATH vs. hard-coded /dev/wdt. From Frank - Benkert (2016-10-21). - * configs/*/defconfig: The buttons example was changed to archbuttons.

The should help performance with MCUs with 32-bit - FPU support with some additional code size (2016-10-22). - * Remove support for software prioritization of interrupts (2016-10-23). - * drivers/net/tun.c: Fix bug in TUN interface driver. From Max - Nekludov (2016-10-24). - * arch/arm/src/stm32: A new implementation of the STM32 F4 I2C bottom - half. The commin I2C as this did not handled correctly in the current - implementation (see also https://github.com/PX4/NuttX/issues/54). The - changes almost exclusively affect the ISR. From Max Kriegleder - (2016-10-24). - * arch/arm/src/stm32l4: Fix I2C devices RCC registers. From Sebastien - Lorquet (2016-10-25). - * arch/arm/src/stm32l4: Enable and renames for 32l4 UARTs 4 and 5. - From Sebastien Lorquet (2016-10-25). - * configs/stm32f103-minimum: Fix Timers 2 to 7 clock frequencies. - From Alan Carvalho de Assis (2016-10-25). - * arch/arm/src/stm32: Initial implemention of the STM32 F37xx SDADC - module. There are also changes to ADC, DAC modules. SDADC has only been - tested in DMA mode and does not support external TIMER triggers. This - is a work in progress. From Marc Rechté (2016-10-25). - * Add logic to attach peripheral interrupt sources to CPU interrupts - (2016-10-25). - * CHxN channels are always outputs. From Sebastien Lorquet - (2016-10-26). - * sched/semaphore: Within the OS, when a thread obtains a semaphore - count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is - enabled. If a count is available, then sem_wait() calls - sem_addholder(), otherwise it waited for the semaphore and called - sem_addholder() when it eventually received the count. - - This caused a problem when the thread calling sem_wait() was very - low priority. When it received the count, there may be higher - priority threads "hogging" the CPU that prevent the lower priority - task from running and, as a result, the sem_addholder() may be - elayed indefinitely. - - The fix was to have sem_post() call sem_addholder() just before - restarting the thread waiting for the semaphore count. - - This problem was noted by Benix Vincent who also suggested the - solution (2016-10-26). - * configs/stm32f103-minimum: Add RGB LED support on STM32F103 Minimum - board. From Alan Carvalho de Assis (2016-10-26). - * arch/arm/src/stm32f7: stm32_i2c.c Dejavu. Fixes a bug previously - found in the F4.

Board support for testing Misoc LM32 with Qemu. - From Ramtin Amin (2016-11-01). - * arch/arm/src/stm32: I think, that Size is (highest address+1 - Base - address). Base address has been removed and if address+count >= size - we are outside of the Flash. From David Sidrane (2016-11-01). - * sched/semaphore, sched/phread/, libc/semaphore, libc/pthread: Add - pthread_mutexattr_get/set_protocol and non-standard sem_get/set_protocol. - These may use to enable or disable priority inheritance on a single - semaphore (2016-11-02). - * arch/arm/src/stm32: Fix ADC compilation error when DMA isn't enabled. - From Paul A. Patience (2016-11-02). - * drivers/ and drivers/spi: Fix Kconfig warning. This commit moves the - ARCH_HAVE_SPI options outside the check for SPI. Those options don't - depend on SPI, and Kconfig files in arch/ enable them even if SPI - isn't enabled. Source the driver's Kconfig in drivers/Kconfig only - if support for the driver is enabled prevents us from defining these - ARCH_HAVE options in the driver's Kconfig. We should probably remove - the other checks in drivers/Kconfig and check if the drivers are - enabled only in their Kconfig. From Paul A. Patience (2016-11-02). - * Move protoypes for the non-standard include/semaphore.h file to the - non-standard include/nuttx/semaphore.h with the other non-standard - semaphore interfaces (2016-11-02). - * include/semaphores.h: Provide macros for sem_setprotocol() and - sem_getprotocol() if priority inheritance is not enabled. More - SEM_PRIO_* definitions to include/nuttx/semaphore.h (2016-11-02). - * drivers/serial.c: Make sure that priority inheritance is not - enabled for the signaling semaphores used in the serial driver - (2016-11-03). - * arch/arm/src/stm32f7: Fix to SPI-Master driver. Without this the - chip select decoding feature will not work properly. From Michael - Spahlinger (2016-11-03). - * drivers/, net/, fs/, sched, arch/, graphics/, libnx,: Disable - priority inheritance on all semaphores used for signaling (2016-11-03). - * sched/semaphore: Handle a case of missing proxy for sem_setprotocol. - Reorder so that (1) this error is avoided, and (2) >No proxy is needed - if priority inheritance is not enabled (2016-11-03). - * config/*/defconfgs: More fallout from name change of - apps/examples/buttons to archbuttons (2016-11-03). - * configs/nucleo_f303re: Various fixes to get the adc configuration - building again after PR. Refresh all configurations (2016-11-03). - * arch/misoc/src/common: Add interrupting Misoc serial driver.

This commit fixes - compilation errors on MPU support for ARMv7-R. From Heesub Shin - (2016-11-06). - * arch/arm/src/armv7-r: Fix invalid drbar handling. In ARMv7-R, - [31:5] bits of DRBAR is physical base address and other bits are - reserved and SBZ. Thus, there is no point in passing other than the - base address. From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Remove the redundant update on SCTLR. - mpu_control() is invoking cp15_wrsctlr() around SCTLR update - redundantly. From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Add new Kconfig entries for d/i-cache. - Unlike in ARMv7-A/M, Kconfig entries for data and instruction caches - are currently missing in ARMv7-R. This commit adds those missing - Kconfig entries. Actual implmenetation for those functions will be - added in the subsequent patches. From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Add cache handling functions. This commit - adds functions for enabling and disabling d/i-caches which were - missing for ARMv7-R. From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Fix typo in mpu support. s/ARMV7M/ARMV7R/g. - From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Fix CPSR corruption after exception handling. - A sporadic hang with consequent crash was observed when booting. It - seemed to be caused by the corrupted or wrong CPSR restored on return - from exception. NuttX restores the context using code like this: - - msr spsr, r1 - - GCC translates this to: - - msr spsr_fc, r1 - - As a result, not all SPSR fields are updated on exception return. - This should be: - - msr spsr_fsxc, r1 - - On some evaluation boards, spsr_svc may have totally invalid value at - power-on-reset. As it is not initialized at boot, the code above may - result in the corruption of cpsr and thus unexpected behavior. - - From Heesub Shin (2016-11-06). - * arch/arm/src/armv7-r: Fix to restore the Thumb flag in CPSR. Thumb - flag in CPSR is not restored back when the context switch occurs while - executing thumb instruction. From Heesub Shin (2016-11-06). - * sched/wqueue: When queuing new LP work, don't signal any threads - if they are all busy. From Heesub Shin (2016-11-06). - * sched/wqueue: Signal sent from work_signal() may interrupt the low - priority worker thread that is already running. For example, the worker - thread that is waiting for a semaphore could be woken up by the signal - and break any synchronization assumption as a result. It also does not - make any sense to send signal if it is already running and busy. This - commit fixes it. From Heesub Shin (2016-11-06). - * arch/arm/src/stm32f7: STM32F7 SD/MMC driver depends on - CONFIG_SDIO_DMA which is only defined in stm32/Kconfig. Changed to - CONFIG_STM32F7_SDMMC_DMA and defined in stm32f7/Kconfig (2016-11-07). - * arch/arm/src/stm32: Add PWM driver support for STMF37xx. The - changes have been tested successfuly for TIM4 and TIM17 (different - IPs). From Marc Rechté (2016-11-07). - * sched/semaphore: sem_trywait() no longer modifies the errno value - UNLESS an error occurs. This allows these functions to be used - internally without clobbering the errno value. From Freddie Chopin - (2016-11-09). - * arch/arm/src/stm32l4: Change the way to configure quadrature encoder - prescalers. From Sebastien Lorquet (2016-11-09). - * libc/unisted: Patch brings strtol() and related functions more - conformant with POSIX. Corner cases like strtol(-2147483648, NULL, 10) - now pass clang -fsanitize=integer without warnings. From Juha Niskanen - (2016-11-10). - * drivers/sensors and configs/stm32f103-minimum: Add Vishay VEML6070 - driver and support for STM32F103-Minimum board. From From Alan - Carvalho de Assis(2016-11-13). - * Misoc LM32: Corrects a bug that never occured in qemu on simulation or - real fpga. The error was that the r1 register was being modified out of - context switching and not restoring it. From Ramtin Amin (2016-11-14) - * arch/arm/src/samv71: A problem occurred with the SAMV7 USBDEVHS driver - if the USB cable is unplugged while a large amount of data is send over - an IN endpoint using DMA. If the USB cable is plugged in again after a - few seconds it is not possible to send data over this IN endpoint again, - all other endpoints work as expected. - - The problem occurs because if the USB cable is unplugged while an DMA - transfer is in flight the transfer is canceled but the register - SAM_USBHS_DEVDMACTRL is left in an undefined state. The problem was - fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a - known state. Additionally all pending interrupts are cleared. - - From Stefan Kolb (2016-11-14). - * configs/esp32-core: ESP32 Core v2: Add configuration to supporting - linking NuttX for execution out of IRAM (2016-11-14). - * libc/unistd: sleep() was returning remaining nanoseconds (kind of), - instead the remaining seconds. From Eunbong Song (2016-11-15). - * sched/irq: Fixes for the SMP case: (1) Change order for SMP case in - enter_critical_section: (1) Disable local interrupts BEFORE taking - spinlock and (2) If SMP is enabled, if any interrupt handler calls - enter_critical_section(), it should take the spinlock. (2016-11-15). - * arch/xtensa: Add EXPERIMENTAL hooks to support lazy Xtensa co- - processor state restore in the future (2016-11-16). - * Add some experimental changes to enter/leave_critical_section to - deal with the case where interrupts are disabled only on the local - CPU (2016-11-16). - * sched/irq: Add logic to handled nested calls to - enter_critical_section() from interrupts handlers (with SMP) - (2016-11-16). - * drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call. - This calls directly from the timer driver into application code. That - is non-standard, non-portable, and cannot be supported (2016-11-17). - *drivers/timer: Add timer driver hooks to support signal notification - of timer expiration. Commented out because invasive interface changes - would also be required to complete the implementation (2016-11-17). - * arch/arm/src/armv7-m: Fix double allocation of MPU region in mmu.h - (2016-11-17). - * timer driver: Use signal to notify of timer expiration. Add generic - argument so that there can be additional usage. From Sebastien Lorquet - (2016-11-17). - * All timer lower half drivers. Port Sebastien's changes to all all - other implementations of the timer lower half. Many changes and - untested. Expect some problems. (2016-11-17). - * sched/irq: irq_csection() has a bad assumption in the SMP case. It - assumed that the state of certain variables. That was true on entry - into the interrupt handler, but might change to the execution of logic - within the interrupt handler (2016-11-18). - * config/ nucleo-l476rg: Add support for timers to nucleo l476. From - Sebastien Lorquet (2016-11-18). - * drivers/net: Add option to use low-priority work queue to all drivers - in drivers/net. Not yet added to all architecture-specific network - drivers (2016-11-18). - * sched/wdog: Most interrupt handling logic interacts with tasks via - standard mechanism such as sem_post, sigqueue, mq_send, etc. These all - call enter_critical_section and are assumed to be safe in the SMP case. - - But certain logic interacts with tasks in different ways. The only one - that comes to mind are wdogs. There is a tasking interface that to - manipulate wdogs, and a different interface in the timer interrupt - handling logic to manage wdog expirations. - - In the normal case, this is fine. Since the tasking level code calls - enter_critical_section, interrupts are disabled an no conflicts can - occur. But that may not be the case in the SMP case. Most - architectures do not permit disabling interrupts on other CPUs so - enter_critical_section must work differently: Locks are required to - protect code. - - So this change adds locking (via enter_critical section) to wdog - expiration logic for the case if the SMP configuration - (2016-11-18). - * SAM3/4: Add delay between setting and clearing the endpoint RESET bit - in sam_ep_resume(). We need to add a delay between setting and - clearing the endpoint reset bit in SAM_UDP_RSTEP. Without the delay the - USB controller will (may?) not reset the endpoint. If the endpoint is - not being reset, the Data Toggle (DTGLE) bit will not to be cleared - which will cause the next transaction to fail if DTGLE is 1. If that - happens the host will time-out and reset the bus. Adding this delay - may also fix the USBMSC_STALL_RACEWAR in usbmsc_scsi.c, however this - has not been verified yet. From Wolfgang Reißnegger (2016-11-18). - * SAM3/4: Remove unused 'halted' flag in UDP driver. From Wolfgang - Reißnegger (2016-11-18). - * SAM3/4: Remove 'stalled' flag in UDP driver. The flag is not necessary. - The state of the endpoint can be determined using 'epstate' instead. - From Wolfgang Reißnegger (2016-11-18). - * USBMSC: Fix length of mode6 sense reply packet. From Wolfgang - Reißnegger (2016-11-18). - * configs/dk-tm4c129x: Typo fix. From Wolfgang Reißnegger (2016-11-18). - * Typo fix in sam_udp.c. From Wolfgang Reißnegger (2016-11-18). - * STM32: STM32F303xB and STM32F303xC chips have 4 ADCs. From Paul A. - Patience (2016-11-19). - * vfork(): Fix a race condition in the SMP case. Existing logic - depended on the fact that the child would not run until waitpid was - called because the child had the same priority as the parent. BUT - in the SMP case that is not true... the child may run immediately on - a different CPU (2016-11-19). - * arch/: Add option to use low-priority work queue to all Ethernet - drivers in arch that support CONFIG_NET_NOINTS (2016-11-19). - * sched/clock: Correct calculation for the case of Tickless mode with - a 32-bit timer. In that case, the calculation was returning - millisecond accuracy. That is not good when the timer accuracy is < 1 - msec. From Rajan Gill (2016-11-19). - * sched/task: task_restart() test not supported on SMP systems. This is - not fully implemented (2016-11-19). - * This commit adds a new internal interfaces and fixes a problem with - three APIs in the SMP configuration. The new internal interface is - sched_cpu_pause(tcb). This function will pause a CPU if the task - associated with 'tcb' is running on that CPU. This allows a different - CPU to modify that OS data stuctures associated with the CPU. When the - other CPU is resumed, those modifications can safely take place. The - three fixes are to handle cases in the SMP configuration where one CPU - does need to make modifications to TCB and data structures on a task - that could be running running on another CPU. Those three cases are - task_delete(), task_restart(), and execution of signal handles. In - all three cases the solutions is basically the same: (1) Call - sched_cpu_pause(tcb) to pause the CPU on which the task is running, - (2) perform the necessary operations, then (3) call up_cpu_resume() to - restart the paused CPU (2016-11-20). - * task_restart: Make sure new task starts with pre-emption disabled and - not in a critical section (2016-11-21). - * Fix a typo in a spinlock macro (2016-11-21). - * Spinlocks: Added capability to provide architecture-specific memory - barriers. This was for i.MX6 but does not help with the SMP problems. - It is still a good feature (2016-11-21). - * Remove a assertion condition that appears to rarely cause false-alarm - assertions. Teported by Petteri Aimonen (2016-11-21). - * The examples/qencoder app was trying to init the encoder by a direct - call into the board, cheating in a local header to declare the normally - unavailable function prototype. From Sebastien Lorquet (2016-11-22). - * configs: All QE encoder files. Last change made timer hard-coded to 3. - Make configurable (2016-11-22). - * configs: Remove all traces of the no-longer existent ARCHBUTTONS - example. Remove all button configurations that depended on the - obsoleted ARCHBUTTON example (2016-11-22). - * nucleo-l476rg: Add better selection of timer (2016-11-22). - * implementation of dumpgpio for stm32l4, was required for pwm debug. - From Sebastien Lorquet (2016-11-22). - * SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting - for g_cpu_irqlock and CPU0 is waitin for g_cpu_paused (2016-11-22). - * Misoc: Add timer driver.

Add SCU register definitions - (2016-11-26). - * i.MX6: Add some controls to enable SMP cache coherency in SMP mode - (2016-11-26). - * ARMv7-A: Fix some SCU SMP logic (2016-11-26). - * ARMv7-A/i.MX6: Modify handling of the SMP cache coherency - configuration so that it is identical to the steps from the TRM. - Makes no differenct, however (2016-11-27). - * The Smoothie project needs to compile C++ inside config/boardname/src/ - to use with High Priority Interruption, then I modified the board - configs Makefile to support it. It works fine for the first time - compilation, but if we execute "touch config/boardname/src/Pin.cxx" - and execute "make" it will not detect that Pin.cxx was modified. I - think there is some other place I should modify, but I didn't find - it. From Alan Carvalho de Assis (2016-11-27). - * ARMv7-A/i.MX6 SMP: Move SMP coherent cache setup to earlier in - initialization of CPUn, n>0 (2016-11-27). - * ARMv7 GIC: SGIs are non-maskable but go through the same path as other, - maskable interrupts. Added logic to serialize SGI processing when - necessary (2016-11-27). - * sched_note: Extend OS instrumentation to include some SMP events - (2016-11-27). - * sched_note: Add spinlock instrumentation; In SMP configurations, - select to log only notes from certain CPUs (2016-11-28). - * Misoc LM3: Add Misoc Ethernet driver. Integrate network support into - configs/misoc/hello. Remove configs/misoc/include/generated directory. - I suppose the intent now is that this is a symbolic link? DANGER! - This means that you cannot compile this code with first generating - these files a providing a symbolic link to this location! From Ramtin - Amin (2016-11-28). - * Add tools/showsize.sh (2016-11-28). - * configs/misoc: Add a sample directory containing generated sources. - This is really only useful for performing test builds. You really - must generate the Misoc architecture for a real-life build. From - Ramtin Amin (2016-11-28). - * sched_note: Permit spinlock and critical section notes in in-memory - buffer iff sched_not_get() interfaces is disabled (2016-11-28). - * STM32 DAC: Fix shift value whenever there are is a DAC2 and, hence, - up to three interfaces.

From Sebastien Lorquet (2016-12-01). - * boardctl: Add new boardctl() command ,BOARDIOC_NX_START, to start the - NX server as a kernel thread (2016-12-01). - * GPDMA driver for the LPC43xx. The GPDMA block is basically the same - as the LPC17xx. Only the clock configuration is different and LPC43xx - has four different DMA request sources, where LPC17xx has only two. - From Alan Carvalho de Assis (2016-12-01). - * Remove RGMP and RGMP drivers (2016-12-02). - * i.MX6: Add an untested SPI driver taken directly from the i.MX1 port - (2016-12-02). - * Eliminate CONFIG_NO_NOINTS.

From Gong Darcy - (2016-12-04). - * SAMA5 does not build when executing from SDRAM before board - frequencies are not constant. Rather, the bootloader configures the - clocking and we must derive the clocking from the MCK left by the - bootloader. This means lots more computations. This is untested on - initial commit because I don't have a good PWM test setup right now - (2016-12-04). - * Olimex-LPC1766-STK: Enable procfs in NSH configuration.

From David Sidrane (2016-12-05). - * Remove BOARDIOC_CAN_INITIALIZE. CAN initialization is now done in the - board initialization logic just like every other device driver - (2016-12-06). - * STM32F7: Allow the config to override the clock edge setting. From - David Sidrane (2016-12-06). - * For Cortex-A9, should also set ACTLR.FW in SMP mode to enble TLB and - cache broadcasts.

From Pierre-Noel Bouteville - (2016-12-10). - * task_delete() now obeys all cancellation point semantics (2016-12-10). - * Add task_setcancelstate(), task_setcanceltype(), and task_testcancel(). - These are non-standard interfaces analogous to the correponding pthread_ - interfaces that provide cancellation controls for tasks (2016-12-10). - * i.MX6 interrupt handling: Additional logic needed to handle nested - interrupts when an interrupt stack is used (2016-12-13). - * SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to - CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node - acknowledges the message sent. This will also occur if the device is - not connected to the can-bus. The CAN-Standard declares, that the Chip - has to retry a given message as long as it is not sent successfully (or - it is not cancelled by the application). Every time the chip tries to - resend the message an Acknowledge-Error-Interrupt is generated. At high - baud rates this can lead in extremely high CPU load just for handling - the interrupts (and possibly the error handling in the application). To - prevent this Interrupt-Flooding we disable the ACKE once it is seen as - long we didn't transfer at least one message successfully. From Frank - Benkert (2016-12-13). - * i.MX6: Remove non-cached, inter-cpu memory region. Not a useful - concept (2016-12-13). - * minnsh Configurations: Remove minnsh configurations and support logic: - up_getc() and lowinstream. This was an interesting exercise to see - just how small you could get NuttX, but otherwise it was not useful: - (1) the NSH code violated the OS interface layer by callup up_getc and - up_putc directly, and (2) while waiting for character input, NSH would - call up_getc() which would hog all of the CPU. Not a reasonable - solution other than as a proof of concept (2016-12-13). - * Calypso Boards: Remove all Calypso board configurations (2016-12-13). - * Calypso: Remove Calypso architecture support and support for Calypso - SERCOMM driver (2016-12-13). - * ESP32 core v2: Two changes (1) flushes the UART TX buffer in the esp32 - serial shutdown routine. The ROM bootloader does not flush the FIFO - before handing over to user code, so some of this output is not - currently seen when the UART is reconfigured in early stages of - startup. And changes the openocd config file's default flash voltage - from 1.8V to 3.3V. This is not necessary right now, but may save some - hard-to-debug moments down the track (3.3V-only flash running at 1.8V - often half-works and does weird things...). From Angus Gratton - (2016-12-14). - * Xtensa ESP32: Add missing ENTRY() and RET() macros in C callable - assembly language. At one time I though the that the ESP32 support the - CALL0 ABI.

Fix errors APP CPU startup (2016-12-20). - * fs/procfs: Fix procfs status for SMP case (2016-12-20). - * Xtensa ESP32: Clock frequency is different if running from IRAM or is - booting from FLASH. This is a booltloader issue (2016-12-20). - * Xtensa ESP32: Basic port is function in both single CPU and dual CPU - SMP configurations. There is an NSH configuration for each CPU - configuration (2016-12-21). - * STM32 F4: Merge in support for the Olimex STM32 P407 board (2016-12-21). - * Xtensa ESP32: Add an OS test to verify the port (2016-12-22). - * Xtensa ESP32: Corrects a problem with dispatching to signal handlers: - Cannot vector directly to the signal handling function as in other ABIs - under the Xtensa Window ABI. In that case, we need to go through a - tiny hook when performs the correct window call (call4) otherwise - registers will be scrambled in the signal handler (2016-12-22). - * SAMV7 CAN: Make delete_filter functions more robust. From Frank - Benkert (2016-12-23). - * Xtensa ESP32: Add stack checking logic (2016-12-23). - * sched note: record ID enumeration now results on constant values; ID - values do not change with configuration.

From David Sidrane - (2016-12-24). - * termios.h: Fix CRTSCTS define to include input and output flow. - From Lorenz Meier (2016-12-26). - * SMP: Enforce this rule: Tasks which are normally restored when - sched_unlock() is called must remain pending (1) if we are in a - critical section, i.e., g_cpu_irqlock is locked , or (2) other CPUs - still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In - those cases, the release of the pending tasks must be deferred until - those conditions are met (2016-12-26). - -7.20 2017-03-08 Gregory Nutt - - * i.MX6 SMP/NSH configuration: Enable examples/smp test (2016-12-27). - * SMP: There were certain conditions that we must avoid by preventing the - release of the pending tasks while withn a critical section. But this - logic was incomplete; there was no logic to prevent other CPUs from - adding new, running tasks while on CPU is in a critical section. This - commit corrects this. This is matching logic in sched_addreadytorun to - avoid starting new tasks within the critical section (unless the CPU is - the holder of the lock). The holder of the IRQ lock must be permitted - to do whatever it needs to do (2016-12-27). - * i.MX6: Fix clearing GPT status register. From Masayuki Ishikawa - (2016-12-28). - * SMP: Make checks for CPU lock set more robust. There are certains - conditions early in initialization on during interrupt handling where - things need to be done a little differently (2016-12-28). - * sched_cpulocked: Avoid use of spinlock. That has been reported to - cause a deadlock (2016-12-28). - * SMP: Fix a gap where we may try to make modifications to the task lists - without being in a critical sections. That permits concurrent access to - the tasks lists and many subtle problems. This fix just remains in the - critical section throughout the operation (and possible until the task - is restore in the event of a context switch). Makes a big difference in - stability (2016-12-28). - * SMP: Move sharable function to common file as irq_cpu_locked(). Use - irq_cpu_locked() in sched_unlock(). Use irq_cpu_locked() in - sched_removereadytorun() and sched_setpriority(). Use irq_cpu_locked() - in sched_mergepending() (2016-12-29). - * Add configuration support for builds with Ubuntu under Windows 10 - (2017-01-01). - * Add support for Tom Thumb small mono-space font. From Alan Carvalho de - Assis (2017-01-03). - * Alternative way to encode font spacing for Tom Thumb font (2017-01-04). - * Graphics: Initial separation of font cache from graphics/nxterm. Now in - libnx/nxfronts where it can be shared with other grapics applications - (2017-01-05). - * Font cache: Fix a reference counting issue: count not be initialized - when font cache created. Fix initialization of a semaphore. Enforce - mutually exclusive access to the font cache Replace fixed-size array - with variable size link list. Font cache in libnx needs to use - context-specific memory allocators (2017-01-06). - * Add debug assertion in libdtoa to catch attempts to use floating point - output formats from within an interrupt handler. That will cause - assertions or crashes downstream because __dtoa will attempt to allocate - memory. From Pierre-noel Bouteville (2017-01-06). - * procfs: Correct to snprintf-related errors in fs_procfsproc.c. - Resolves issue #24 (2017-01-07). - * STM32F429i Discovery: Add support for NxWM on STM32F429i-Disco board. - From Alan Carvalho de Assis (2017-01-07). - * STM32F429i-DISCO: Enable keyboard input in nxwm configuration - (2017-01-07). - * STM32F429i-DISCO: Change NxWM cursor character from 137 (graphics - block) to 95 (underscore). NxWM is configured to use a 7-bit character - set so 137 is not a valid character code (2017-01-07). - * NX server: Correct message queue names. Should not be at /dev, but - rather relative to /var/mqueue (2017-01-08). - * NxWM configurations. If using a 7-bit character set, then the cursor - character cannot be 137 (graphic block). Use 95 (underscore) instead - (2017-01-08). - * packed_struct replaced by begin_packed_struct and end_packed_struct. - From Aleksandr Vyhovanec (2017-01-09). - * sched_note: Fix spinlock instrumentation. From Masayuki Ishikawa - (2017-01-12). - * SMP: Fix an error in critical section logic when performing a context - switch from an interrupt handler. The g_cpu_irqset bit was not being - set for the CPU so other CPUs did not know about the critical section - (2017-01-13). - * Kinetis: Added support for CHIP_MK60FN1M0VLQ12 chip. From Maciej - Skrzypek (2017-01-13). - * Kinetis: Fixed wrong MCG VDIV calculation on new NXP K60. From Maciej - Skrzypek (2017-01-13). - * Kinetis Serial: Fixed compile error when UART5 is selected.

From Maciej Skrzypek - (2017-01-13). - * Kinetis: New K60 has no Flex memory. From Maciej Skrzypek (2017-01-13). - * In all implementations of _exit(), use enter_critical_section() vs. - disabling local interrupts (2017-01-13). - * i.MX6: Corrects behavior of last SMP patch with i.MX6 (2017-01-13). - * SMP Signals: Fix some SMP signal delivery logic. Was not handling some - critical sections correctly and was missing logic to signal tasks - running on other CPUs (2017-01-14). - * STM32F103 Minimum: Add support for nRF24 on STM32F103-Minimum board. - From Alan Carvalho de Assis (2017-01-15). - * Kinetis: Add support for K64/K66 RTC lower half driver. From Neil - Hancock (2017-01-17). - * Networking: Fixed some issues that prevented ipv6 to work with ipv4 - enabled. From Pascal Speck (2017-01-18). - * STM32 Oneshot: Fix logic so that it can support multiple oneshot timers - (2017-01-18). - * STM32L4: Port fix for multiple oneshot timers from STM32. Also fixes a - few issues with original STM32 implementation (2017-01-18). - * SAM3/4: Add support for ATSAM4S4C. From Wolfgang Reißnegger (2017-01-18). - * Math library: Leverage optimized ARM functions from BSD license ARM file - (2017-01-19). - * Math library optimatizations for FPU only apply to ARMv8 which is not - yet supported (2017-01-20). - * Move optimized ARM memcpy functions from arch/arm/src/ to - libc/machine/. This is necessary for the PROTECTED and KERNEL build - modes. Otherwise, memcpy() will be built in to kernel space and not - accessible to applications (2017-01-20). - * libc: Fix ARMv7-A/R memcpy assembly (2017-01-20). - * ARM memcpy(): Use DWord vs. HWord offset. ARM 32-bit instructions must - be aligned to DWord boundaries and this gives us more range in the jump - tables (2017-01-20). - * Fix a compile error: in sched_cpuload.c:Line136, the variables ts and - secs are not defined if CONFIG_CPULOAD_ONESHOT_ENTROPY = 0. However, - these variables are used regardless of CONFIG_CPULOAD_ONESHOT_ENTROPY at - lines~180:onwards. From Rajan Gill (2017-01-22). - * CPU load: Correct computation of the nominal period to use when the - source is a oneshot timer (2017-01-22). - * Kernel Modules: Module initializer may now return a symbol table - (2017-01-22). - * Modules: Extend the module interface so that we can access symbols - exported by the module (2017-01-22). - * Shared Libraries: In the FLAT build mode, kernel modules may be used to - provide minimal shared library functionality (2017-01-22). - * Shared libraries: Add a non-standard dllfnc.h function to set the - symbol table (2017-01-23). - * Olimex-stm32-p407: Add a NSH protected build configuration; Enable - procfs/ in all configurations (2017-01-23). - * SMP: Fix timer related issues: Round robin and sporadic scheduling - were only being performed for tasks running on the CPU that processes - the system timer interrupt. Similary, CPU load measurements were only - be processed for running on the CPU that receives the sampling interrupt - (2017-01-23). - * STM32 F7: Added missing ARCH_HAVE_RESET for F7.

Remove PINCONFIG_DIGITAL. From Alan Carvalho de Assis - (2017-01-26). - * sched/modules: Add support for dependencies between modules (2017-01-27). - * Back out use on inline functions to access 16-bit registers. The inline - functions were a work-around for misbehaving compiler years and years - ago. The mon standard macro-ized version should work just fine - (2017-01-27). - * Olimex STM32 P407: Add support for on-board microSD slot. Does not - work... Currently all commands to the SD card timeout (2017-01-28). - * libc/modlib: Add build a configuration logic for a shared module - library (2017-01-29). - * Module names are not needed in libc/modlib when the module library is - used only for shared library support (2017-01-29). - * Shared Libs: Implement module based shared libraries for the PROTECTED - mode build (2017-01-29). - * Typos withim mtd/ with Macronix MX25L. In NuttX/drivers/mtd/Make.defs - letters X between M and 25 are missing. Noted by Oleg Evseev - (2017-01-x30x). - * SAME70-Xplained: Clone some recent SAMV71-XULT changes (2017-01-30). - * Add capabilities() method to SDIO interface. Remove - CONFIG_SDIO_WIDTH_D1_ONLY. That should not be a global propertie, but - rather a capability/limitation of single slot when there may be multiple - slots (2017-01-31). - * Removed dmasupported() method from the SDIO interface. That is now a - bit in the capability set (2017-01-31). - * STM32F7 SDMMC: Add support for single bit operation on SDMMC2 - (2017-01-31). - * STM32F103-Minimum: Fix a compile error. - CONFIG_STM32_TICKLESS_ONESHOT_TIMER is only defined in TICKLESS mode. - Somebody has been hand editing .config files (2017-01-31). - * Timer logic: Add private function prototypes to eliminate a warning; - Functions should not be inline because the may recurse (2017-01-31). - * STM32F7 SDMMC: Make sure that all SDMMC configuration variables begin - with STM32F7_; Eliminate CONFIG_SDMMC1/2_DMA altogether.

From Marc Rechté (2017-02-06). - * SDIO interface: Handle all possible DMA combinations in all SDIO drivers - (2017-02-07). - * up_timer_initialize() is named incorrectly. The prefix should be the - architecture name, not up_ since it is private to the architecture. - up_timerisr() is similarly misnamed and should also be private since it - is used only with the xyz_timerisr.c files (2017-02-07). - * MCG defines are based on the MCG feature configuration. We define the - bits as a common set of names. This means that an index may be added to - a name i.e. LOCK is LOCK0 as that is the superset name. From David - Sidrane (2017-02-07). - * Fixes illdefined BOARD_FR_DIV with BOARD_FRDIV from MCG. Original - BOARD_FR_DIV was never used - that is a good thing because the value ws - defined shifted and the code also shifted it. From David Sidrane - (2017-02-07). - * Added MCG settings that are defiend on the K64 SoC. Added - BOARD_MCG_C2_FCFTRIM and BOARD_MCG_C2_LOCRE0 to configure the MCG_C2 - register cleanup of some comments. From David Sidrane (2017-02-07). - * Better granualarity and errno checking of the board's MCG settings. - Allow for complete MCG_C2 definition from the boart.h file. Moved - #ifdef out of code by setting default values. Allow for individule bit - setting in MCG_C2 for BOARD_EXTCLOCK_MCG_C2, BOARD_MCG_C2_FCFTRIM, - BOARD_MCG_C2_LOCRE0.

Returning immediately in - the case of a NAK makes the Mass Storage Class driver unreliable. - The retry/timeout logic is necessary.

If if a NAK is received - with no data, then no longer returns the NAK error immediately but - retries until data is received or a timeout occurs. Initial testing - indicates that this fixes the issues the MSC.

Remove all traces of - CONFIG_EXAMPLES_USBTERM* and all of the illegal device support - (2017-03-09). - * Save elapsed time before handling I2C in stm32_i2c_sem_waitstop(). - This patch follows the same logic as in previous fix to - stm32_i2c_sem_waitdone(). It is possible that a context switch - occurs after I2C registers are read but before elapsed time is saved - in stm32_i2c_sem_waitstop(). It is then possible that the registers - were read only once with "elapsed time" equal 0. When scheduler - resumes this thread it is quite possible that now "elapsed time" will - be well above timeout threshold. In that case the function returns - and reports a timeout, even though the registers were not read - "recently". Fix this by inverting the order of operations in the loop - - save elapsed time before reading registers. This way a context - switch anywhere in the loop will not cause an erroneous "timeout" - error. From Freddie Chopin (2017-03-10). - * pthreads: Fix pthread_mutexattr_init(). It was not initializing the - protocol field when priority inheritance is enabled (2017-03-10). - * Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is - only a single, hard-allocated holder structure. This is problem - because in sem_wait() the holder is released, but needs to remain in - the holder container until sem_restorebaseprio() is called. The call - to sem_restorebaseprio() must be one of the last things the - sem_wait() does because it can cause the task to be suspended. If in - sem_wait(), a new task gets the semaphore count then it will fail to - allocate the holder and will not participate in priority - inheritance. This fix is to add two hard-allocated holders in the - sem_t structure: One of the old holder and one for the new holder - (2017-03-10). - * STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to - similar STM32 I2C drivers.

Convert obsolete dbg() macros to current info(), warn(), - err() macros (2017-03-15). - * sem_holder: Fixes improper restoration of base_priority in the case - of CONFIG_SEM_PREALLOCHOLDERS=0. The call to - sem_restorebaseprio_task context switches in the - sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to - releasing the holder. So the running task is left as a holder as is - the started task. Leaving both slots filled thus failing to perform - the boost/or restoration on the correct tcb. This PR fixes this by - releasing the running task slot prior to reprioritization that can - lead to the context switch. To faclitate this, the interface to - sem_restorebaseprio needed to take the tcb from the holder prior to - the holder being freed. In the failure case where sched_verifytcb - fails it added the overhead of looking up the holder. There is also - the additional thunking on the foreach to get from holer to - holder->tcb. An alternate approach could be to leve the interface - the same and allocate a holder on the stack of sem_restoreholderprioB - copy the sem's holder to it, free it as is done in this pr and and - then pass that address sem_restoreholderprio as the holder. It could - then get the holder's tcb but we would keep the same sem_findholder - in sched_verifytcb. From David Sidrane (2017-03-15). - * ARM: Remove redundant interrupt stack coloring.

Erase a sector from the second bank cause the bit 4 of SNB - being set but never unsed, so trying to erase a sector from the first - bank was acually eraseing a sector from the second bank. From José - Roberto de Souza (2017-03-22). - * STM32: Make up_progmem thread safe. Writing to a flash sector while - starting the erase of other sector have a undefined behavior so lets - add a semaphore and syncronize access to Flash registers. But for - the semaphore to work it needs to be initialized so each board needs - call stm32_flash_initialize() on initialization, so to avoid runtime - problems it is only using semaphore and making it thread safe if - initialized, after all boards starts to call stm32_flash_initialize() - we can remove the boolean and the check. From José Roberto de Souza - (2017-03-22). - * STM32: Add workaround for flash data cache corruption on - read-while-write. This is a known hardware issue on some STM32 see - the errata of your model and if you make use of both memory banks you - should enable it. From José Roberto de Souza (2017-03-22). - * Clicker2-STM32: Add framework for MRF24J40 support. Untested and - still some missing logic (2017-03-22). - * STM32 Flash fixes.

From Aleksandr - Vyhovanec (2017-03-24). - * I needed to use DS3231, I remember that in past it worked ok, but now - for stm32f4xx is used another driver (chip - specific, stm32f40xxx_i2c.c) and DS3231 driver doesn't work. After - investigating a problem I found that I2C driver (isr routine) has a - few places there it sends stop bit even if not all messages are - managed. So, e.g., removing stm32_i2c_sendstop (#1744) and adding - stm32_i2c_sendstart after data reading helps to make DS3231 working. - From Alexander Oryshchenko; verified by David Sidrane (2017-03-24). - * wireless/ieee802154: Adds IOCTL definitions for accessing PHY - layer.

Add pthread_mutex_consistent() to - recover from this situation (2017-03-26). - * pthread: Fix return value of pthread_give/takesemaphore(). Add - option to pthread_takesemaphore to ignore EINTR or not (2017-03-26). - * pthreads: Partial implementation of final part of robust mutexes: - Keep list of all mutexes held by a thread in a list in the TCB - (2017-03-26). - * when pthread exits or is cancelled, mutexes held by thread are marked - inconsistent and the highest priority thread waiting for the mutex is - awakened (2017-03-26). - * pthreads: Add a configuration option to disable robust mutexes and - revert to the traditional unsafe mutexes (2017-03-26). - * pthread mutexes: Add option to support both unsafe and robust - mutexes via pthread_mutexattr_get/setrobust() (2017-03-26). - * pthread mutexes: Finish logic to support configuration mutex - robustness (2017-03-27). - * Rename CONFIG_MUTEX_TYPES to CONFIG_PTHREAD_MUTEX_TYPES (2017-03-27). - * Make sure that CONFIG_PTHREAD_MUTEX_ROBUST=y is selected every - configuration that enabled pthreads (2017-03-27). - * Add syscall support for pthread_mutex_consistent() (2017-03-27). - * Include wcstold in C++ cwchar header file. From Alan Carvalho de - Assis (2017-03-27). - * AT86RF23x: Clean-up, standardize lower half interface.

From Martin - Lederhilger (2017-03-28). - * realloc(): When realloc() has to fall back to calling malloc(), size - including overhead was being provided to malloc(), causing a slightly - larger allocation than needed. Noted by initialkjc@yahoo.com - (2017-03-28). - * Fix PTHREAD_MUTEX_INITIALIZER which was not updated with last mutex - changes. From Jussi Kivilinna (2017-03-28). - * STM32 F7: Add stm32 RNG support. This is copied from stm32l4. - Tested on STM32F746ZG board. From Juha Niskanen (2017-03-29). - * STM32 RNG: Fix semaphore initial value and disable priority - inheritance. From Juha Niskanen (2017-03-29). - * Fix an assertion noted by Jussi Kivilinna. This was a consequence of - the recent robust mutex changes. If robust mutexes are selected, - then each mutex that a thread takes is retained in a list in threads - TCB. If the thread exits and that list is not empty, then we know - that the thread exitted while holding mutexes. And, in that case, - each will be marked as inconsistent and the any waiter for the thread - is awakened. For the case of pthread_mutex_trywait(), the mutex was - not being added to the list! while not usually a fatal error, this - was caught by an assertion when pthread_mutex_unlock() was called: - It tried to remove the mutex from the TCB list and it was not there - when, of course, it shoule be. The fix was to add - pthread_mutex_trytake() which does sem_trywait() and if successful, - does correctly add the mutext to the TCB list. This should - eliminated the assertion (2017-03-29). - * 6LoWPAN: IEEE802.15.4 MAC driver will need a special form of the - network device structure to manage fragmentation of the large packet - into frames (2017-03-29). - * wireless/ieee802154: Adds MAC character driver structure. - Nonfunctional.

From Anthony Merlino (2017-03-29). - * net/local: connect: Fix warning with gcc-arm-none-eabi-5-2016q1. - Using compiler from gcc-arm-none-eabi-5-2016q1 toolchain: - - gcc version 5.3.1 20160307 (release) [ARM/embedded-5-branch revision 234589] (GNU Tools for ARM Embedded Processors) - - gives error: - - local/local_connect.c:188:7: error: '_local_semtake' is static but used in inline function 'local_stream_connect' which is not static [-Werror] - - this is due to compiler enforcing ISO/IEC 9899:1999 6.7.4.3: "An - inline definition of a function with external linkage shall not - contain a definition of a modifiable object with static storage - duration, and shall not contain a reference to an identifier with - internal linkage." Fix by making inlined caller to have internal - linkage as well. From Juha Niskanen (2017-03-30). - * Add entropy pool and strong random number generator. Entropy pool - gathers environmental noise from device drivers, user-space, etc., - and returns good random numbers, suitable for cryptographic use. - Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm - for CSPRNG output. Patch also adds /dev/urandom support for using - entropy pool RNG and new 'getrandom' system call for getting - randomness without file-descriptor usage (thus avoiding - file-descriptor exhaustion attacks). The 'getrandom' interface is - similar as 'getentropy' and 'getrandom' available on OpenBSD and - Linux respectively. From Jussi Kivilinna (2017-03-30). - * Change STM32 tickless to use only one timer. From Konstantin - Berezenko (2017-03-30). - * drivers/sensors: Add driver for ST HTS221 humidity sensor.

Tested - with earlier version of NuttX; with current version checked that it - compiles. Via Juha Niskane (2017-03-31). - * Add user-space networking stack API (usrsock). User-space networking - stack API allows user-space daemon to provide TCP/IP stack - implementation for NuttX network. Main use for this is to allow use - and seamless integration of HW-provided TCP/IP stacks to NuttX. For - example, user-space daemon can translate /dev/usrsock API requests to - HW TCP/IP API requests while rest of the user-space can access - standard socket API, with socket descriptors that can be used with - NuttX system calls.

From Jussi Kivilinna (2017-04-06). - * STM32F7: Default CONFIG_STM32F7_DMACAPABLE to 'n'. STM32F7 does not - have CCM RAM but DTCM, so this option does not need to enabled. DTCM - RAM is DMA-able through CPU AHBS bus. From Jussi Kivilinna - (2017-04-06). - * STM32F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi - Kivilinna (2017-04-06). - * STM32F7: Add warning for RXDMA + IFLOWCONTROL combination. - Combination of RXDMA + IFLOWCONTROL does not work as one might - expect. Since RXDMA uses circular DMA-buffer, DMA will always keep - reading new data from USART peripheral even if DMA buffer underruns. - Thus this combination only does following: RTS is asserted on USART - setup and deasserted on shutdown and does not perform actual RTS - flow-control. Data loss can be demonstrated by doing long up_mdelay - inside irq critical section and feeding data to RXDMA+IFLOWCONTROL - UART. From Jussi Kivilinna (2017-04-06). - * sim/sixlowpan: Now supports apps/examples/udpblaster too (2017-04-06). - * SAMV7: Watchdog: Fix Forbidden Window Value. According the Datasheet - the WDD Value is the lower bound of a so called Forbidden Window and - to disable this we have to set the WDD Value greater than or equal to - the WDV Value. This seems to be a bug in the datasheet. It looks - like we have to set it to a greater value than the WDV to really - disable this Thing. When triggering the Watchdog faster than the - (very slow) clock source of the Watchdog fires, this Forbidden Window - Feature resets the System if WDD equals to WDV. This Changeset - disables the Forbidden Window by setting the WDD Value to the Maximum - (0xfff) Value possible. From Frank Benkert (2017-04-06). - * RTC: Add interface for check if RTC time has been set. New interface - allows checking if RTC time has been set. This allows to application - to detect if RTC has valid time (after reset) or should application - attempt to get real time by other means (for example, by launching - ntpclient or GPS).

From Juha Niskanen - (2017-05-11). - * mtd: Fix some unallocated and NULL pointer issues. rwb->wrflush and - rwb->wrmaxblocks in rwbuffer could get unallocated values from - ftl_initialize() in some configurations. Also fixes related assert: - - up_assert: Assertion failed at file:rwbuffer.c line: 643 - - that can happen with the following configuration: - - CONFIG_FTL_WRITEBUFFER=y - CONFIG_DRVR_WRITEBUFFER=y - # CONFIG_FS_WRITABLE is not set - - These problems are caused by CONFIG variable differences between the - buffer layers. TODO: This is not a perfect solution. readahead - support has similar issues. From Juha Niskanen (2017-05-11). - * STM32L4: port stm32l4_serial_get_uart function from STM32F7. From - Juha Niskanen (2017-05-12). - * syslog: Avoid flushing syslog_stream buffer, if possible, until - lib_vsprintf() completely parses the format. This assures that the - flush will flush the entire output, even data that may potentially - follow the linefeed. And, in that case, it cannot be interleaved - with other devug output. Suggested by Jussi Kivilinna (2017-05-12). - * syslog: There is yet another place where the output can get split. - That is in syslog_dev_write(): It will break up the stream to insert - a CR before the LF. This can that can be avoid be generating the - CR-LF sequence in the buffer and then detecting and ignoring valid - CR-LF sequences, rather than expecting syslog_dev_write() to insert - the CR in this case. I don't like the idea that syslog_dev_write() - still scans the entire output buffer to expand CR-LF sequence. This - seems really wasteful, especially in this case where we can be sure - that the is no CR or LF without a matching LF or CR. Bu, I think, - the existing behavior in syslog_dev_write() must be retained because - it is needed in other contexts (2017-05-12). - * Bitbucket Issue 47: Some of last syslog changes needed to be - condition on #ifdef CONFIG_SYSLOG_BUFFER in order to be built without - syslog buffering enabled (2017-05-12). - * Move CAN subsystem to its own directory and put device drivers - there.

From Gwenhael - Goavec-Merou (2017-05-13). - * Kconfig/deconfigs: Add CONFIG_ARCH_TOOLCHAIN_GNU to indicate that - the toolchain is based on GNU gcc/as/ld.

From Juha Niskanen (2017-05-15). - * drivers: rename newly introduced up_i2creset to I2C_RESET. From - Juha Niskanen (2017-05-15). - * TCP: An RST received during the 3-way handshake requires a little - more clean-up (2017-05-15). - * STM32 CAN: I had the problem that the transmit FIFO size (= actual - elements in FIFO) was slowly increasing over time, and was full after - a few hours. The reason was that the code hit the line - "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so - can_xmit thinks it has sent the packet to the hardware, but actually - has not. Therefore the transmit interrupt never happens which would - call can_txdone, and so the size of the FIFO size does not decrease. - The reason why the code actually hit the mentioned line above, is - because stm32can_txready uses a different (incomplete) condition than - stm32can_send to determine if the mailbox can be used for sending, - and thus can_xmit forwards the packet to stm32can_send. - stm32can_txready considered mailboxes OK for sending if the mailbox - was empty, but did not consider that mailboxes may not yet be used if - the request completed bit is set - stm32can_txinterrupt has to - process these mailboxes first. Note that I have also modified - stm32can_txinterrupt - I removed the if condition, because the CAN - controller retries to send the packet until it succeeds. Also if the - condition would not evaluate to true, can_txdone would not be called - and the FIFO size would not decrease also. From Lederhilger Martin - (2017-05-16). - * drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY - for DIOC_GETPRIV command. It should returns OK if DIOC_GETPRIV - command succeeds. From EunBong Song (2017-05-16). - * There can be a failure in IOB allocation to some asynchronous - behavior caused by the use of sem_post(). Consider this scenario: - (1) Task A holds an IOB.  There are no further IOBs.  The value of - semcount is zero. Task B calls iob_alloc().  Since there are not - IOBs, it calls sem_wait().  The value of semcount is now -1. (2) - Task A frees the IOB.  iob_free() adds the IOB to the free list and - calls sem_post() this makes Task B ready to run and sets semcount to - zero NOT 1.  There is one IOB in the free list and semcount is zero. - When Task B wakes up it would increment the sem_count back to the - correct value. (3) But an interrupt or another task runs occurs - before Task B executes.  The interrupt or other tak takes the IOB off - of the free list and decrements the semcount.  But since semcount is - then < 0, this causes the assertion because that is an invalid state - in the interrupt handler. So I think that the root cause is that - there the asynchrony between incrementing the semcount. This change - separates the list of IOBs: Currently there is only a free list of - IOBs. The problem, I believe, is because of asynchronies due - sem_post() post cause the semcount and the list content to become out - of sync. This change adds a new 'committed' list: When there is a - task waiting for an IOB, it will go into the committed list rather - than the free list before the semaphore is posted. On the waiting - side, when awakened from the semaphore wait, it will expect to find - its IOB in the committed list, rather than free list. In this way, - the content of the free list and the value of the semaphore count - always remain in sync (2017-05-16). - * stm32_serial: Fix freezing serial port. Serial interrupt - enable/disable functions do not disable interrupts and can freeze - device when serial interrupt is received while execution is at those - functions. Trivially triggered with two or more threads write to - regular syslog stream and to emergency stream. In this case, freeze - happens because of mismatch of priv->ie (TXEIE == 0) and actually - enabled interrupts in USART registers (TXEIE == 1), which leads to - unhandled TXE interrupt and causes interrupt storm for USART.

Basically, the delay - that was added during the integration of the CDC/ACM host driver was - interfering with streaming audio. That delay was put there to - prevent build endpoints from hogging the system bandwidth. So what - do we do? Do we hog the bandwidth or do we insert arbitrarity - delays.

From David Sidrane (2017-06-02). - * Kinetis: usbdev clean up ensuring proper use of HW. Remove magic - numbers from code, documented the use of undocumented bits. Remove - comments and code that were not appropriate for this hardware. - Removed ifdef that's that were always compiled and removed code - blocks that were never compiled. Ensure proper access order to - hardware. Per the reference manual: disable endpoints prior to - configuring buffer descriptor, then enable endpoints Reorganize - interrupt processing order to offload data after processing errors. - Reorganize initialization so that there is a clear initialization - phase, reset phase for both the hardware and software structures. By - breaking the initialization into smaller pieces, the reset interrupt - only resets the resources within the controller that should be reset. - Rework suspend and resume logic so they perform properly. Made attach - and detach functions optional. As they do not make sense for a bus - powered device. Ensured the calls to up_usbinitialize - up_usbuninitialize do not violate the USB spec. From David Sidrane - (2017-06-02). - * WIP: wireless/ieee802154: More work on association/beacon-enabled - networks. From Anthony Merlino (2017-06-02). - * We developed a huge Changeset over a year ago to make USB Composite - configuration dynamical and be able to instanciate the CDCACM - multiple times inside this device. We use this feature to switch - between one in normal and up to three CDCACMs in maintenance boot. - The control path starts in boardctl.c where the configuration for the - device is constructed. There are still a few issues which I'll ask - you to have a look at before this beast can be merged. (1) To be - able to construct the data dynamically I have changed some - USB-Structs to be packed. Maybe there are additional structs to - change (just for completeness – not for current functionality). (2) - I've added the Macro COMPILE_TIME_ASSERTION two times (in - usbmsc_desc.c and in cdcacm_desc.c) to stay private. Maybe you’ll - find a better place. It’s used to check the size of the structs - against the assumptions. (3) I've changed the interface for some - USB-Functions to receive also the dynamic configuration. Maybe this - can be done more elegant. (4) The original NuttX (without the patch) - seems to have problems with a Composite device holding a CDCACM and - an MSC. The USB SET CONFIGURATION request does not to work at all. - This makes the test fail under Windows and under Linux. Applying this - patch doesn’t change anything – because it only changes the - configuration – not the behavior. Maybe you’ll have a look at - this problem before applying the patch.

The standard C++ ABI that - most platforms follow defines __guard to be 64 bits. The existing - implementation of libxx_cxa_guard.cxx follows this. However, the - 32-bit ARM C++ ABI defines it as 32 bits instead, and changes the - meaning slightly so only the lowest bit is used. This matters because - GCC creates guard symbols without regards to what libxx_cxa_guard.cxx - says. So on ARM, gcc allocates 4 bytes, but __cxa_guard_release - writes 8 bytes, zeroing out another unlucky variable nearby. Fix it - by special-casing 32-bit ARM in libxx_cxa_guard.

With - this change, the endpoints which are the 'points' of the star will - forward all traffic to the coordinator. The coordinator is assumed - to be the 'hub' of the star. This function also implements IPv6 - forwarding. That forwarding implementation is minimal, just enough - to support the forwarding requirements of the star hub node - (2017-06-28). - * Clicker2-STM32 + net/: Add configurations to support the endpoint - and hub roles in a star topology. Fix various things that broke when - IPv6 forwarding was enabled (2017-06-29). - * 6LowPan: Change how the destination node address is handled in the - star endpoint configuration. When the star endpoint sent the IPv6 - destination address, the HC06 compression logic elided the address -- - meaning that it could be reconstructed by the recipient based on the - receiver's assigned short address. However, when intercepted by the - hub, the uncompressed address does not know the short address of the - recipient and instead uses the short address of the hub. This means - two things: (1) it looks like the hub address is the destination - address, and (2) the uncompressed UDP packet has a bad checksum. - This change assures that the destination IPv6 address is not elided - in the case of the star endpoint configuration (2017-06-30). - * 6LoWPAN: Fix a misconception about HC06 16-bit IPv6 address - compression (2017-06-30). - * 6LoWPAN fix compile issue in star hub configuration (2017-06-30). - * This change backs out the 'misconception' fix of - 76e6dba2e4bfab9515bef2866c5c59fd2a2f0fa0 and reimplements it in a way - that actually seems to work (2017-06-30). - * ieee802154: Random fixes to get beacon-enabled networking more - stable.

Last of the conversions of defconfig files to - compressed format (2017-07-09). - * ieee802154: Improves internal timer logic to handle work serially. - Before, the MAC timer used a watchdog to schedule work with the high - priority worker queue. However, since everything in the MAC is - supposed to be serialized through the use of the high priority work - queue, but the timer uses a watchdog, there are some unintended - consequences. To simplify, we now use the delayed work feature of the - work queue. From Anthony Merlino (2017-07-09). - * Update configure.sh, configure.bat, configure.c: With compressed - format, part of the installation requires that we run 'make - olddefconfig' to restore the uncompressed defconfig format. Also, - while I was at it, I also added options to select host platform on - configure command line (2017-07-10). - * tools/refresh.sh: Now runs make savedefconfig before copying the new - defconfig file in place; Also, added a new option --defaults. Since - the number of defaults that you now have to answer is so large, the - option lets you just accept the default values. So it works just - like --slilent but still prompts you for the decision to save or - discard the new defconfig file (2017-07-10). - * tools/tesbuild.sh: Fix missing $ before variable name (2017-07-10). - * configs/clicker2-stm32: Adds support for per-function-call stack - checking.

From Jeff - (2017-07-28). - * We discovered a problem with the samv7 mcan driver which results, - under some circumstances, in a very high CPU load. The problem - occurs, and is easily reproducible, if the device is connected to a - CAN network with a wrongly configured CAN speed (baud rate). In our - tests we set the CAN speed of the device to 1000000 and the speed of - the other CAN nodes to 500000. The device is restarted and sends a - CANopen "bootup message" to the CAN network. This results in huge - amount of errors messages on the CAN bus, probably because of the CAN - feature for acknowledging error messages. The error messages can’t - be read by the device because of the misconfigured CAN speed, instead - the CAN chip reports lots of errors, which are reported to the - application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled). - The CAN errors are reported from the CAN chip via interrupts and thus - the interrupt load is very high in this scenario. To fix the problem - the driver now disables each RX error interrupt after it is occurred. - The RX error interrupts are turned back on if at least one CAN - message is received successfully. From Stefan Kolb (2017-07-28). - * tcdrain implementation based on a new term ioctl. From Sebastien - Lorquet (2017-07-28). - * Spirit Network Driver: Create build directories, Add radio - initialization, interrupt handling logic, packet transmissin and - reception logic.

From Titus von Boxberg (2017-07-29). - * STM32_RCC_DCKCFGR2 has nothing to do with PLLI2S; PLLI2S is not - dependent on LTDC, instead on SAICLK1/2 generated from PLLI2S. From - Titus von Boxberg (2017-07-29). - * To use an external oscillator module (not just a crystal) with the - STM32F4, one needs to enable the HSEBYP bit in the RCC_CR register. - This change allows an integrator to define STM32_RCC_CR_HSEBYP in - their board.h file if they want this configuration. From Jeff - (2017-07-30). - * 6LoWPAN PktRadio: Some initial changes to support raw packet radios - without IEEE 802.15.4 with 6LoWPAN. Add missing MetaData-related - prototypes and initialization logic. Perform a major renaming to - make room in the 6LoWPAN name space for packet radios. Replace - metadata input parameter type from struct ieee802154_data_ind_s to - void*. This permits radios with different MAC metadata to interact - with 6LoWPAN. Includes many changes to handle variable length radio - addresses. No longer just short and exteneded; any length.Remove - explicit type struct ieee802154_frame_meta_s from derive interface - methods.

MAX_PATH may already be defined - in included system files. From Jeff (2017-08-04). - * Spirit1 network drvier: Increase number of retries if there is no - acknowledgement; Add interrupt handling for the case where the max - number of retries expires.

From Masayuki - Ishikawa (2017-08-07). - * Spirit bugfixes: Was hanging occasionally because there was no - mechanism to restart the poll timer if poll was not performed because - Spirit ws busy. Fixed by not checking if Spirit is busy. The TX - poll can be performed asynchronouly while spirit is busy; any - outgoing data will queued until Spirit is ready. Fixed handling of a - timeout condition. Failure to transmition to the TX state would fail - (timeout) if in a race condition Spirit already committed to the RX - state. The driver needs to recover the state properly and avoid - debug assertions in this event (2017-08-07). - * STM32 USB: I'm working on bringing up USB full-speed support on - STM32F405.  My board does not include a USB power switch, VBus - sensing, over current detection, or ID pin. This commit add a - config STM32_OTGFS_VBUS_ CONTROL which lets us selectively disable - VBus sensing and control.  I also sneaked in a change to disable the - configgpio call for the ID pin, which is only used in OTG mode which - isn't supported yet.  The only pins that need to be initialized - should be OTGFS_DP and OTGFS_DM. These changes let a USB mouse - enumerate on my platform if it's plugged in on power-up.  Plugging, - unplugging, clicking, or moving the mouse cause NSH to stop - responding.  Because I'm using the ramlog, I don't have useful debug - messaging yet, so there's a lot more work I have to do to - troubleshoot it or get my JTAG debugging set up, but these patches - shouldn't hurt anything.  I'm hoping my issue is something simple I - overlooked in configuration. From Jeff (2017-08-07). - * I discovered while working on the SAMV7 mcan driver that the - implementation of the CAN error handling is suboptimal. In the - current implementation the many errors are implemented as pending - errors. But those errors are not pending, the errors occurred and - are gone directly afterwards. This commit changes the described - behavior and simplifies the handling of CAN errors. From Stefan Kolb - (2017-08-07). - * IPv6: Remove comparisons to the address with all ones set.

From Masayuki Ishikawa (2017-08-09). - * Update NSH documentation to show new usage for addroute and delroute - (2017-08-10). - * cwchar: Use CONFIG_LIBC_WCHAR to only export the wc/mb functions. - When a build does not want to use wide or multibyte char - CONFIG_LIBC_WCHAR is not set. Therefore we should to only export the - wc/mb functions when defined. Regardless of the stat of - CONFIG_LIBC_WCHAR the non mb/wc definitions such as mbstate_t, - wint_t, wctype_t need to be exported. From David Sidrane - (2017-08-10). - * inet_ntop: Was printing negative values for fields >127 - (2017-08-11). - * procfs: Add support for routing tables at proc/net/route - (2017-08-11). - * Unify GCC/Clang config. From Goran Mekić (2017-08-12). - * procfs routing table: Don't print the IPv4 routing table header if - the table is empty. Fix a couple of places where CONFIG_NET_IPv4 was - used wehre IPv6 was intended (not noticed now because I am testing - with both enabled) (2017-08-12). - * C++: Compilation with recent C++ compiler needs an overloaded delete - operator that includes a size_t size argument (2017-08-12). - * ARM: The older ARM7 and ARM9 configurations were determining CFLAGS - based on the GCC version 4.x.x or not. That needx to be extended for - 5.x.x and 6.x.x which also behave like 4.x.x (2017-08-12). - * STM32F7: Some STM32F7 builds failed in build testing due to undefined - STM32_SRAM1_BASE. I think that is because stm32_allocateheap.c was - not including chip/stm32_memorymap.h (2017-08-13). - * Fix ESP32 gpio enable reg and default UART pin. Modify default uart - pin for ESP-WROOM-32. Fix gpio enable reg. From Sungki Kim - (2017-08-13). - * stm32/stm32f0: Fix some funny shifts in DAC header files.

Updated - comment to proper refernce manual for STM32F7 not STM32F4. Added - stm32_dmacapable input paramaters documentation. From David Sidrane - (2017-08-17). - * STM32 F7: DMA add dcache alignment check in stm32_dmacapable. In the - case dcache write-buffed mode is used (not write-through) buffer - alignment is required for DMA transfers because a) - arch_invalidate_dcache could lose buffered writes data and b) - arch_flush_dcache could corrupt adjacent memory if the maddr and the - mend+1, the next next address are not on ARMV7M_DCACHE_LINESIZE - boundaries. From David Sidrane (2017-08-17). - * STM32 F7: SDMMC remove widebus limitation on DMA. There is no - documantation for the STM32F7 that limits DMA on 1 bit vrs 4 bit - mode. From David Sidrane (2017-08-17). - * dcache write-buffed mode is used (not write-through) buffer alignment - is required for DMA transfers because a) arch_invalidate_dcache could - lose buffered writes data and b) arch_flush_dcache could corrupt - adjacent memory if the buffer and the bufflen, are not on - ARMV7M_DCACHE_LINESIZE boundaries. From David Sidrane (2017-08-17). - * STM32 F7: SDMMC add dcache alignment check in dma{recv|send}setup. - In the case where CONFIG_SDIO_PREFLIGHT is not used. - * drivers/sensors: Add support to HC-SR04 distance sensor. From Alan - Carvalho de Assis (2017-08-17). - * PF_IEEE802154 address family: With this commit PF_IEEE802154 address - family is basically functional. More testing is needed, of course: - Finishes up socket interfaces connect() sendto(), recvfrom(), and - bind() logic. Special initialization, device lookup, driver poll, - and frame input logic. Add configs/sim configuration for testing - (2017-08-19). - * STM32 COMP: add default INM configuration and some missing - COMP1,3,5,7 code. From Mateusz Szafoni (2017-08-20). - * 6LoWPAN/PF_IEEE802154: Created radiodev.h and renamed various - structures to provide a better separation between 6LoWPAN networking - and PF_IEEE802154 address family (2017-08-20). - * STM32 DAC: fix some configuration logic. When STM32_NDAC is greather - than 1, then second channel is always DAC1OUT2. From Mateusz Szafoni - (2017-08-20). - * PF_IEEE802154 address family: IEEE 802.15.4 network device: Make - same changes as per loopback device so that it will build with - PF_IEEE802154 but without 6LoWPAN. More fixes to device registration - and to IEEE 802.15.4 loopback driver for PF_IEEE802154 without - 6LoWPAN. Changes to conditional compilation so that PF_IEEE802154 - can build without 6LoWPAN (2017-08-20). - * drivers/net/tun.c: Currently cannot support TAP mode unless Ethenet - is enabled (2017-08-20). - * PktRadio loopback driver: Fix compile problem by removing - inappropriate const storage class (2017-08-20). - * Networking: Remove driver based backlog support. This affects the - entire network, but is used by only one driver. The only supported - RX backlog is now via common read-ahead buffering (2017-08-21). - * PF_IEEE802154 socket family: (1) Improve some backlog counting - logic; add more assertions to catch cases where the backlog count - might deviate from the actual backlog. (2) Add a maximum backlog - option. This will prevent overrun of the RX frame queue if many - frames are received from the radio, but no application is receiving - the queued data. (3) On input, there may be a list of frames - provided, not just one. When closed() and connection is freed, also - need to free any frames remaining in the RX queue (2017-08-21). - * Network procfs: Add support for network procfs statistics when - nothing is enabled but PF_IEEE802154 (2017-08-21). - * STM32 DAC: Add support for HRTIM triggering. Separate dma buffer - configuration for channels. From Mateusz Szafoni (2017-08-21). - * ENCX24J600: Fix some warnings.

From Pekka Ervasti - (2017-08-22). - * STM32L4 COMP: Bind to upper half comp driver. From Pekka Ervasti - (2017-08-22). - * STM32L4 ADC: correct EXTSEL macros. From Juha Niskanen - (2017-08-22). - * drivers/lcd: ssd1306: (1) Separate lcd_dev_s setup to separate - object. g_oleddev takes 1 KiB because framebuffer and was allocated - to .data section because of lcd_dev_s function pointer setup. Move - lcd_dev_s setup out, so that g_oleddev goes to .bss and avoid wasting - ROM. (2) Fix memory corruption caused by ssd1306_getrun(). - ssd1306_getrun was writing one extra byte (with value 0) past target - buffer when pixlen is multiple of 8. When pixlen was not multiple of - 8, last byte of buffer was fully cleared, instead of modifying only - the (pixlen % 8) bits of last byte. (3) Add support for board power - control. ThingseeOne has regulator for controlling display power - on/off. Patch adds support for board based power control to SSD1306 - driver. (4) Add DD-12864WO-4A/SSD1309 support to SSD1306 driver. - From Jussi Kivilinna (2017-08-22). - * Network procfs: procfs/net_procfs_route.c building error occur if - CONFIG_NET_ROUTE is enabled.

From Juha Niskanen - (2017-08-25). - * STM32L4 DAC: report transfer as completed in DMA callback. Without - this even O_NONBLOCK writes block the calling task if DAC was using - DMA. From Juha Niskanen (2017-08-25). - * STM32L4 COMP: comparators share RCC enable bit with SYSCFG. From - Juha Niskanen (2017-08-25). - * power: add driver for TI bq2429x battery charger. TODO: Untested. - Does not have poll() support. From Juha Niskanen (2017-08-25). - * 6LoWPAN: The original, Contiki-based design used only a single - buffer for reassemblying larger packets. This could be a problem - issue for hub configurations which really need the capability - concurrently reassemble multiple incoming streams concurrently. - These was also a design issue in that the reassembly buffer could be - corrupted by outgoing packets. The design was extended to support - multiple reassembly buffers, each associated with the reassembly tag - and source address. This assures that there can be be no corruption - of the reassembly once it has started (2017-08-26). - * Simulator: Adds necessary functionality to build Simulator under ARM - Linux. Tested only on Raspberry3. Currently setjmp/longjmp do not - save/restore floating point registers. From Nickolay Semyonov - (2017-08-26). - * fs: FS_AUTOMOUNTER should depend on SCHED_LPWORK.

Frpm Juha - Niskanen (2017-08-28). - * STM32L4 ADC: implement peripheral. From Juha Niskanen (2017-08-28). - * work_queue() must cancel existing work prior to queuing new work, - otherwise the work queue list structure can become corrupted. - Problem noted by Pascal Speck (2017-08-28). - * STM32 HRTIM: Add DMA configuration. From Mateusz Szafoni - (2017-08-28). - * Networking: Move TCP specific files from inet/ to tcp/. There is - another TCP-specific logic in inet/ that should be moved sometime, - but those are more entangled (2017-08-29). - * Networking: TCP disconnection callbacks are not retained in a list. - This will support multiple callbacks per lower-level TCP connection - structure. That is necessary for the cae where a socket is dup'ed - and shares the same lower-level connection structure. NOTE: There - still needs to be a call to tcp_start_monitor() when the socket is - dup'ed (2017-08-29). - * Networking: Start the network monitor for a socket when a TCP socket - is dup'ed (2017-08-29). - * Networking: A placeholder for some missing logic in the previous - change related to monitoring network status for dup'ed sockets. If - one of the dup'ed socket's is closed, then network monitor resources - associated with that one socket must be recovered. Also, in the - event that socket is being used on one thread, but then closed on - another, any threads waiting for events from the socket should be - informed of the closure. That latter requirement is not implemented - because current data structures do not support it (2017-08-29). - * Networking: Clean up some naming that has bothered me for a long - time... There are no interrupts and no interrupt handlers in the - network. There are events and event handler (there used to be - interrupt logic in there years ago but that is long, long gone) - (2017-08-29). - * configs: update STM32L4 configs for ADC changes. From Juha Niskanen - (2017-08-30). - * configs: update STM32L4 configs for ADC changes. From Juha Niskanen - (2017-08-30). - * Porting Guide: Add usage tip for reading CAN messages from the CAN - driver without losing message (2017-08-30). - * Networking: socket dup() conditional operation was missing the test - for the condition (2017-08-30). - * ARMv7-M syscall logic: Clear bit 0 in PC settings. Bit 0 is the - thumb mode indication and should not be set in the PC. This extra - bit has not caused problems in the past, but seeing it set in the PC - is unnerving (2017-08-30). - * Networking: Fix a race condition. The accept() operation is - performed with the network locked. However, the network is unlocked - BEFORE the connected state is set. Therefore, a context switch may - occur and the socket may no longer be connected when it is marked so. - Noted by Pascal Speck (2017-08-31). - * Work queue: In a recent change for a problem noted by Pascal Speck, - it was noted (again by Pascal Speck) that the cancellation of - existing work and replacement with new work must be atomic. Thanks, - Pascal (2017-08-31). - * LPC43xx: Modify up_allocate_(k)heap() to support PROTECTED mode. - From Alan Carvalho de Assis (2017-08-31). - * STM32 Timer: Add the set counter function for stm32 timers.

From - Juha Niskanen (2017-08-29). - * STM32L4 DAC: Fix naming so that DAC1 and DAC2 always refer to - channels 1 and 2. User should not be bothered by details like how - many IP blocks there are. As no current STM32L4 has second DAC block - (channel 3), remove support for such hypothetical hardware. DMA - channels corrected. From Juha Niskanen (2017-09-01). - * configs/nucleo-l496zg: add DAC and missing TIM frequencies. From - Juha Niskanen (2017-09-01). - * Networking: net_timedwait() and net_lockedwait() no longer return - errors via errno but returned negated errno values like other - internal OS functions (2017-09-01). - * Networking: Fix net_lock returning ERROR when instead of real error - code on failure. From Jussi Kivilinna (2017-09-01). - * net/local: Fix server lc_waitsem overflow. From Jussi Kivilinna - (2017-09-01). - * drivers/bch: Add poll support. From Jussi Kivilinna (2017-09-01). - * STM32 F7: do not enable read-modify-write on DTCM. "AN 4667 - - STM32F7 Series system architecture and performance" recommends to - disable read-modify-write on DTCM: "If the DTCM-RAM is used as data - location and the variables used are byte or/and halfword types, since - there is no ECC management in this RAM on the STM32F7 Series, it is - recommended to disable the read-modify-write of the DTCM-RAM in the - DTCM interface (inthe DTCMCR register) to increase the performance." - From Jussi Kivilinna (2017-09-01). - * Networking: IGMP: Remove special support for interrupt level - processing (there is none) and fix some timer cancellation logic. In - many files, correct comments. There is no interrupt level processing - in the networking layer (2017-09-02). - * stm32_dac.c: fix compilation when DMA disabled for channel. From - Mateusz Szafoni (2017-09-02). - * Extend the RTC framework with an alarm read ioctl (RTC_RD_ALARM). - Through it consumer could get configuration settings about previously - scheduled hardware alarms (active status, hours, minutes, seconds). - From Boris Astardzhiev (2017-09-03). - * STM32 F7: Port Boris Astardzhiev's RTC change for STM32L4 to STM32F7 - (2017-09-03). - * STM32: Port Boris Astardzhiev's RTC change for STM32L4 to STM32 - (2017-09-03). - * Kinetis: Unverified implementation of the alarm read function. - Pretty simple because the Kinetis RTC is just a 1Hz counter - (2017-09-03). - * STM32 HRTIM: add burst mode configuration, rename some definitions. - From Mateusz Szafoni (2017-09-03). - * Update net_timedwait() and net_lockedwait() call sites to handle - negated errno in return value.

From Oleg Evseev - (2017-09-08). - * Update/fix last commit: On some STM32's, the CSR regiser is 18 vs. 16 - bits wide. Need to use 32-bit register accesses (2017-09-08). - * 6LoWPAN: I believe, based on RFC review, that with the last multicast - change, the NuttX 6LoWPAN is now compliant with RFC 6282 (2017-09-08). - * arch/arm/Kconfig: Add more classic ARM11 architecture selections - (2017-09-09). - * 6LoWPAN/Radio: Rename radio property sp_pktlen to sp_framelen. Add - 6LoWPAN utility to get the max frame length (not yet hooked in) - (2017-09-10). - * 6LoWPAN: Remove the option to disable fragmentation support. Two - reasons: (1) First fragementation is always required because IPv6 - requires an MTU of 1280 bytes. The is no application use case that can - work without fragmentation support. And (2) it greatly reduces the - complexity of the code (2017-09-10). - * net/sixlowpan: Remove CONFIG_NET_6LOWPAN_FRAMELEN.

Prior to this - change, routing tables were only support in RAM and had to be - initialized with explicit logic to add the necessary routes to the - routing table. With this change, routes may be defined in the - pre-initialized, read-only routing table provided by the board-specific - logic - - This would be particularly useful, for example, in the case where - there is only a single network adaptor and you want all output packets - to go to the single adaptor in all cases. So for that behavior you - could add a read-only routing table to the board-specific long that - contains a single entry, the default route: 0.0.0.0/0 (2017-09-28). - * fs/vfs: file_seek() is an internal OS interface and should not errors - via the errno (2017-09-28). - * fs/vfs: file_read() is an internal OS interface and should not errors - via the errno (2017-09-28). - * fs/vfs: file_write() and file_pwrite() are internal OS interfaces and - should not report errors via the errno (2017-09-28). - * STM32L4 FLASH, DFSDM: option bytes, JEXTSEL bits, ADC1 output to DFSDM - chips change - - STM32L4 FLASH: add function for modifying device option bytes - - STM32L4 DFSDM: add JEXTSEL bits, ADC1 output to DFSDM chips change - ST's documentation hints that ADC output can be routed to DFSDM on - some STM32L4X3 chips, but I got confirmation from tech support that - this is just a documentation error so remove this from Kconfig - From Juha Niskanen (2017-09-29). - * This commit adds support for routing tables in files in a file - system. This might be useful for customized, per-unit routing tables. - There are two issues with it however: - 1. Reading from file system on a per packet basis could be slow. I - think it probably should have a small, in-memory cache of most - frequently used routes for good problem. - 2. Currently the delroute logic is disabled due to a problem with - the design. NuttX does not currently support truncate(). - Therefore, it is not possible to delete entries from the routing - table file. - In this current implementation, that leaves the last entry intact at - the end of the file. An alternative design might include a tag on - each record to indicate if the record is valid or not. That would - work but would add complexity to the other routing table functions - (2017-09-29). - * net/route: Add support for an in-memory routing table cache in order - to improve performance when the routing table is retained in a file. - The cache holds the most recently used routing table entries and so can - eliminate some file access. Flush the in-memory cache when any entry is - deleted from the routing table. When a router matching an IP address is - found, add the routing table entry to the cache (2017-09-29). - * fs/vfs: null check for path on open and buf on write. Null path - check is depend on CONFIG_DEBUG_FEATURES and CONFIG_DEBUG_ASSERTIONS, - added null checking so it's always performed Added null checking on buf - for write(). From Xiao Qin (2017-09-29). - * net/route: File read/write logic should be able to handle short reads - and writes (2017-09-29). - * drivers/syslog: syslog internal functions should not set the errno - variable: ramlog_putc(), syslog_dev_putc(), syslog_dev_write(), - syslog_force() (2017-09-29). - * net/sockets: psock_sendto() is an internal OS interface an should not - set the errno variable (2017-09-29). - * net/sockets: psock_send() is an internal OS interface an should not - set the errno variable (2017-09-29). - * psock_send() no longer sets errno, so send() must now set it - (2017-09-30). - * net/: Versions of psock_send() and pock_sendto() should not set - errno.

From Mateusz Szafoni (2017-10-01). - * tools/configure.c: Duplicate new functionaity added to configure.sh - (2017-10-01). - * tools/configure.sh: Another fix for the script. The last change only - worked for Windows Cygwin; for Linux, it needed to remove some - additional things from the defconfig file (2017-10-01). - * configs/z80sim: convert other configurations to default to Linux - (2017-10-01). - * tools/: configure.sh and configure.c should redirect stdout to - /dev/null but should not suppress stderr output (2017-10-01). - * stdnoreturn.h: Add definitions for the C11 noreturn keyword. Also - Remove C++11 dependency.

From - Alan Carvalho de Assis (2017-10-02). - * syscall/: The non-standard interface exec() is now enshrined as a - official NuttX API. I really dislike doing this but I think that this - is probably the only want to load programs in the protected mode. It is - currently used by some example code under apps/ that generate their own - symbol tables for linking. Other file execution APIs relay on a symbol - table provided by the OS. In the protected mode, the OS cannot provide - any meaning symbol table for execution of code in the user-space blob so - that is they exec() is really needed in that build case. And, finally, - the interface is completely useless and will not be supported in the - KERNEL build mode where the contrary is true: An application process - cannot provide any meaning symbolic information for use in linking a - different process (2017-10-03). - * STM32L4 RTC, PM: small fixes to subseconds handling, ADC - power-management hooks - - STM32L4 ADC: add PM hooks from Motorola MDK - - STM32L4 RTC: add up_rtc_getdatetime_with_subseconds - - STM32 RTC: workaround for potential subseconds race condition. In - all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed - to lock the values in the higher-order calendar shadow registers - until RTC_DR is read. However many old chips have in their errata - this silicon bug (at least F401xB/C, F42xx, F43xx, L15xxE, L15xVD - and likely others): "When reading the calendar registers with - BYPSHAD=0, the RTC_TR and RTC_DR registers may not be locked after - reading the RTC_SSR register. This happens if the read operation is - initiated one APB clock period before the shadow registers are - updated. This can result in a non-consistency of the three - registers. Similarly, RTC_DR register can be updated after reading - the RTC_TR register instead of being locked." - - STM32L4 RTC: correct RTC_SSR and RTC_TR read ordering. In all - recent STM32 chips reading either RTC_SSR or RTC_TR is supposed to - lock the values in the higher-order calendar shadow registers until - RTC_DR is read. Change the register read ordering to match this and - don't keep a workaround for a hypothetical race condition (not in - any L4 errata, lets for once assume ST's silicon works as it is - documented...) - - STM32L4 PM: remove useless #ifdefs and old non-L4 STM32 code - From Juha Niskanen (2017-10-03). - * sched/semaphore: Rename sem_reset() to nxsem_reset() so that it is - clear this is an internal OS function (2017-10-03). - * sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it - is clear this is an internal OS function (2017-10-03). - * libc/semaphore: Add nxsem_init() which is identical to sem_init() - except that it never modifies the errno variable. Changed all - references to sem_init in the OS to nxsem_init() (2017-10-03). - * sched/semaphore: Rename all internal private functions from sem_xyz - to nxsem_xyz. The sem_ prefix is (will be) reserved only for the - application semaphore interfaces (2017-10-03). - * libc/semaphore: Add nxsem_getvalue() which is identical to - sem_getvalue() except that it never modifies the errno variable. - Changed all references to sem_getvalue in the OS to nxsem_getvalue() - (2017-10-03). - * libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and - nxsem_setprotocola which are identical to sem_getprotocol() and - set_setprotocol() except that they never modifies the errno variable. - Changed all references to sem_setprotocol in the OS to - nxsem_setprotocol(). sem_getprotocol() was not used in the OS - (2017-10-03). - * sched/semaphore: Add nxsem_destroy() which is identical to - sem_destroy() except that it never modifies the errno variable. Changed - all references to sem_destroy() in the OS to nxsem_destroy() (2017-10-03). - * sched/semaphore: Add nxsem_post() which is identical to sem_post() - except that it never modifies the errno variable. Changed all - references to sem_post in the OS to nxsem_post() (2017-10-03). - * sched/semaphore: Add the function nxsem_wait(). This is a new - internal OS interface. It is functionally equivalent to sem_wait() - except that (1) it is not a cancellation point, and (2) it does not set - the per-thread errno value on return. In all OS functions (not - libraries), change sem_wait() to nxsem_wait(). This will prevent the OS - from creating bogus cancellation points and from modifying the per-task - errno variable. This commit also backs out most of commit - b4747286b19d3b15193b2a5e8a0fe48fa0a8638c. That change was added because - sem_wait() would sometimes cause cancellation points inappropriately. - But with these recent changes, nxsem_wait() is used instead and it is - not a cancellation point (2017-10-04). - * sched/semaphore: sem_timedwait() is a cancellation point and, hence, - cannot be called from within the OS. Created nxsem_timedwait() that is - equivalent but does not modify the errno and does not cause - cancellation. All calls to sem_timedwait() change to calls to - nxsem_timedwait() in the OS (2017-10-05). - * sched/semaphore: sem_trywait() modifies the errno value and, hence, - should not be used within the OS. Use nxsem_trywait() instead - (2017-10-05). - * This change renames all internal, private NuttX signal-related - functions to use the prefix nxsig_ so that they cannot be confused with - application interfaces that begin, primarily, with sig_. This is - analogous to similar renaming that was done previously for semaphores - (2017-10-05). - * drivers/input/cypress_mbr3108: Add missing variable for nxsem_wait - return value. From Jussi Kivilinna (2017-10-06). - * fs/vfs and net/socket: fcntl() is not return success fail for - F_SETFL. Reported by Jussi Kivilinna (2017-10-06). - * This commit adds internal versions of the signal interfaces: - - sigtimedwait() -> nxsig_timedwait() - - sigwaitinfo() -> nxsig_waitinfo() - - nanosleep() -> nxsig_nanosleep() - Replace all usage of sigwaitinfo(), sigtimedwait(), and nanosleep() - with the OS internal counterparts nxsig_waitinfo(), nxsig_timedwait(), - and nxsig_nanosleep(). The internal OS versions differ from the - standard application interfaces in that they do not create - cancellation points and they do not modify the application's errno - variable (2017-10-06). - * Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These - differ from the standard sleep() and usleep() in that (1) they don't - cause cancellation points, and (2) don't set the errno variable (if - applicable). All calls to sleep() and usleep() changed to calls to - nxsig_sleep() and nxsig_usleep() (2017-10-06). - * drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C - library. But there is a problem. The specification of tcdrain() - requires that it be a cancellation point. In order to do this, tcdrain - was moved from the C library into the OS and the addition cancellation - point hooks were added. In non-FLAT builds, access via system calls is - also now supported (2017-10-06). - * net/Kconfig: Remove improper use of comma in syntax (2017-10-06). - * mm/: Heap semaphore logic needs to use nxsem_* interfaces when - available, but the standard semaphores only when implementing a - user-space heap. Not this does introduce and issue: the memory - management functions them become cancellation points because of the use - of sem_wait (2017-10-07). - * syscall/: Fix some backward conditional compilation (2017-10-07). - * sched/signal: Add nxsig_kill() which is functionally equivalent to - kill() except that it does not modify the errno variable. Replace all - usage kill() in the OS proper with nxsig_kill() (2017-10-07). - * graphics/vnc/server: Fix an error in the VNC server introduced with - recent big set of changes (2017-10-07). - * sched/signal: Add nxsig_queue() which is functionally equivalent to - sigqueue() except that it does not modify the errno variable. Replace - all calls to sigqueue() in the OS proper with calls to nxsig_queue() to - avoid accessing the errno variable (2017-10-07). - * sched/signal: Add internal OS interface nxsig_procmask(). This - internal interface is equivalent to the standard sigprocmask() used by - applications except that it does not modify the errno value. Also fixes - a problem in that the original sigprocmask() was not setting the errno. - Replace all calls to sigprocmask() in the OS proper with calls to - nxsig_procmask(). (2017-10-07). - * sama5d4-ek: Remove a really old defconfig example file that is so far - out of date that it can only be misleading (2017-10-07). - * Fix some build problems after recent separation of internal OS from - application interfaces. The build problem only occurs in the PROTECTED - and KERNEL builds where separate libraries are built for the - applications and for use within the OS. In these cases, the correct - interfaces must be used. This commit fixes a few of these, so I can get - through build testing, but there are many more that need fixin' - (2017-10-08). - * SDCC Fixes: Change some prototypes and some assumptions about the - size of unsigned int to get to a clean SDCC compile (2017-10-08). - * Fix some problems in the previous commits: Forgot to update sigset() - after change to prototype. Also there was a stray semicolon in the - change signal() (2017-10-08). - * libc/stdio: Build the lib_noflush() and lib_snoflush() stubs even if - CONFIG_FILE_DESCRIPTORS=0. They may still be needed (2017-10-08). - * configs/z80sim: Fix a naming problem. Also, don't try to build the - serial driver if CONFIG_NFILE_DESCRIPTOR=0 (2017-10-08). - * libc and libnx: When the libraries are built into two libraries, a - user space library and a OS space library (as in the PROTECTED and - KERNEL build). Then the user space library must not use the OS internal - interfaces; similarly, the OS must avoid using the userspace interfaces - so that it does not muck the errno value or create spurious cancellation - points (2017-10-08). - * Misc STM32 Fixes - - stm32_hrtim.c: fix burst mode prescaler update - - stm32f334-disco: add flash mode support for powerled driver + - cosmetics - From Mateusz Szafoni (2017-10-08). - * powerled.h: Add fault field to state structure.

This includes several register definition header files - (some from Alan Carvalho de Assis), basic interrupt handling logic, - boot-up files, GPIO support, build and configuration logic, basic board - support at configs/pizero (2017-10-09). - * sched/mqueue: Add internal function nxmq_send() and nxmq_timedsend() - that are equivalent to mq_send() and mq_timedsend() except that they do - not create cancellation points and do to not modify the errno variable. - Change all calls to mq_send() and mq_timedsend() in the OS to calls to - nxmq_send() and nxmq_timedsend(), making appropriate changes for - differences in return values (2017-10-10). - * sched/mqueue: Add nxmq_receive() and mxmq_timedreceive() which are - functionally equivalent to the standard mq_receive and mq_timedreceive() - except that (1) they do not create cancellation points, and (2) the do - not modify the application's errno variable. Change all calls to - mq_receive() and mq_timedreceive() in the OS to calls to nxmq_receive() - and nxmq_timedreceive(), making appropriate changes for differences in - return values (2017-10-10). - * Fix a few places where there was a semicolon following the 'if' - condition, making the following logic unconditional (2017-10-10). - * The INA219 is a combined voltage and current sensor that can measure - up to 26 volts and a current that depends on an external shunt - resistor. Connection happens via i2c/smbus and the chip features a - power supply rail that is independent from the measured voltage, so it - can measure low voltages. - - This commit adds a driver for this chip. Right now it measures bus - voltage and current, and does not use the internal calibrated current - reading, nor the available power measurement. From Sebastien Lorquet - (2017-10-10). - * configs/clicker2-stm32: Adds SD card, automount, and syslog file - support and fixes a few minor issues - - Moves defines for xbee from clicker2-stm32.h to stm32_xbee.h - - Adds support for uSD click boards and automount support - - Fixes minor guard clause - - Bring-up automounter before MMCSD - - MRF24J40 interrupt should only fire on falling edge. - - Adds file syslog support for logging to file on SD card - From Anthony Merlino (2017-10-11). - * Z80: Makefile fix for use with current SDCC (2017-10-11). - * fs/vfs: Change the return value of internal function fs_getfilep(). - It no longer sets the errno variable but, rather, returns errors in the - same manner as other internal OS functions (2017-10-11). - * Adds OS internal functions nx_send(), ns_recv(), and nx_recvfrom() - which are functionally equivalent to send(), recv(), and recvfrom() - except that they do not set the errno variable and do not cause - cancellation points (2017-10-11). - * Adds OS internal function nx_write() which is functionally equivalent - to write() except that it does not set the errno variable and do not - cause cancellation points (2017-10-11). - * sched/task: task_exithook.c fails to link if signals are disabled - because was unconditionally trying to send the SIGCHLD signal to the - parent in certain configurations. Noted by Jeongchan Kim (2017-10-11). - * arch/arm/src/samv7: Correct an error in RX DMA setup. From Manish - Kumar Sharma (2017-10-11). - * net/socket: psock_send/psock_sendto: remove assert check for null - psock and buf input pointers. Removes check as 'psock == NULL' - altogether because that checked for later in psock_send and - psock_sendto. Change null check for 'buf' so that it is handled same as - in recvfrom.c (return -EINVAL instead of assert). From Jussi Kivilinna - (2017-10-11). - * fs/vfs: Add new internal OS interface nx_read(). nx_read() is - functionally equivalent to read() except that it does not modify the - errno variable and it is not a cancellation point. Changed all - references to read() in the OS to nx_read() (2017-10-11). - * sched/signal: Add logic to wake up a thread that is waiting on a - signal if it is canceled (2017-10-12). - * nxsig_timedwait: Add logic to suppress the wait if there is a pending - cancellation (2017-10-12). - * stm32 SPI: Add missing include required when CONFIG_SPI_CALLBACK is - enabled. From Anthony Merlino (2017-10-12). - * STM32L4 RTC fixes: - - STM32L4 RTC: init mode was never exited because nested locking in - rtc_synchwait() disabled backup domain access - - STM32L4 RTC: Use backup register magic value instead of INITS - bit. The INITS (bit 4) of RTC_ISR register cannot be used to - reliably detect backup domain reset. This is because we can operate - our device without ever initializing the year field in the RTC - calendar if our application does not care about correct date being - set. Hardware also clears the bit when RTC date is set back to year - 2000. - - STM32L4 RTC: put back the SSR race condition workaround. ST has - confirmed that the issue has not been fixed, and that it applies to - STM32L4 too (was not in errata sheets due to documentation bug) See - discussion: https://community.st.com/thread/43710-issue-with-rtc-maximum-time-resolution - - STM32F4, STM32L4, STM32F7 RTC: add more CONFIG_RTC_NALARMS > 1 to - reduce code size - - STM32L4: rename stm32l4_rtcc.c to stm32l4_rtc.c to better match - STM32F7 - - STM32, STM32L4, STM32F7 RTC: stray comment and typos in - chip/stm32_rtcc.h - - STM32L4 RTC: change maximum alarm time from 24h to one month - From Juha Niskanen (2017-10-13). - * TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a situation - where a NULL pointer may be dereferenced. In this configuration, the - TCP connection's 'semi-permanent' callback, s_sndcb was nullified in - tcp_close_disconnect. However, other logic in tcp_lost_connection() - attempt to use that callback reference after it was nullifed. Fixed in - tcp_lost_connectino() by adding a NULL pointer change before the - access. This was reported by Dmitriy Linikov in Bitbucket Issue 72 - (2017-10-13). - * stm32f7 BBSRAM: stm32_bbsram: avoid assert in stm32_bbsram_savepanic. - If panic happens before stm32_bbsram is initialized, - stm32_bbsram_savepanic caused additional assert panic. Function has null - pointer check, so drop DEBUGASSERT. From Jussi Kivilinna (2017-10-13). - * FS FAT: Fix hard-fault when listing contents of FAT root. From Jussi - Kivilinna (2017-10-13). - * configs/stm32f4discovery: Add a USB MSC configuration. From Alan - Carvalho de Assis (2017-10-13). - * 6LoWPAN: Correct a bug in handling uncompressed frames (IPv6 - dispatch) (2017-10-13). - * 6LoWPAN: Fix a whole in the logic of the previous commit. It turns - out that g_uncomp_hdrlen has other usages so it cannot be modified as I - was doing. Instead, I needed to add a separate localt variable, - protosize, to keep track of the two usages of g_uncomp_hdrlen - (2017-10-13). - * configs/: The nx and nxtext examples no longer supports single user - mode (2017-10-14). - * The lcdrw example has been removed because it violates the portable OS - interface (2017-10-14). - * All configurations that use NXIMAGE or NXHELLO must select - NX_MULTIUSER. All configurations that use examples/nxterm must enable - CONFIG_LIB_BOARDCTL (2017-10-14). - * configs/stm32f103-minimum: Add support for LM75 in the - stm32f103-minimum board. From Alan Carvalho de Assis (2017-10-14). - * configs/: All configurations that use NXLINES must select - NX_MULTIUSER. All configurations that use the NX server need to have - larger POSIX messages (2017-10-14). - * boardctl(): Remove the BOARDIOC_GRAPHICS_SETUP command (2017-10-15). - * Initial ADC support for the STM32F33XX - - stm32_adc.h: add JEXTSEL definitions and hrtim trigger configuration - - stm32_adc.c: move STM32F33 ADC logic to a separate file - From Mateusz Szafoni (2017-10-15). - * configs/sim: Update touchscreen driver initialization to use only - multiple-user NX server logic (2017-10-15). - * configs/sim: Convert the traveler configuration so that it uses the - framebuffer driver (2017-10-16). - * task_delete(): Do not permit user applications to delete kernel - threads (2017-10-16). - * kthread_create(): Rename kernel_thread() to kthread_create() for - better naming consistency with task_create() and kthread_delete() - (2017-10-16). - * All other STM32: SHIFTR_SUBFS_MASK was correct in STM32F0 only - - STM32L1: use correct EXTI line definitions (2017-10-17). - * STM32 RTC fixes: - - RTC: canceling an alarm marks it as inactive - - STM32L4, STM32F4, STM32F7 RTC: fix reading alarm value that is - more than 24h in future - - STM32F0 RTC: fix backup register count in stm32_rtcc.h - From Juha Niskanen (2017-10-17) - * BCM2708: Add system timer register definitions and a partial - implementation of the tickless mode timer (2017-10-17). - * BCM2708: Add support for AUX interrupts. Add some build configuration - and support logic for low-level serial output (2017-10-17). - * drivers/usbdev: Correct input flow control logic when watermarks are - not enabled. Problem noedt by and change based on suggestion by Juha - Niskanen (2017-10-18). - * BCM2708: Add hooks to support both Mini- and PL011 UARTs (2017-10-18). - * BCM2708: Fleshes out GPIO interrupt logic (2017-10-18). - * fs/vfs: Fix after recent changes. write() was return negative values - in errno. Noted by Jussi Kivilinna (2017-10-18). - * drivers/usbdev: Move test for NULL pointer before the pointer is - deferences. Noted by Juha Niskanen (2017-10-18). - * net/: Fix some build issues noted when both IPv4 and IPv6 are - enabled. From Anthony Merlino (2017-10-18). - * photon: Support SPI1 and SPI3. From Anthony Merlino (2017-10-18). - * BCM2708: Allow pass parameters with AUX interrupts; Add mini-UART - break capability. BCM2708: Add Mini-UART logic. Still missing UART - configuration logic (2017-10-18). - * Alexey T, Bitbuck Issue 73: Lower part of STM32 CAN driver - arch/arm/src/stm32/stm32_can.c uses all three hw tx mailboxes and clears - TXFP bit in the CAN_MCR register (it means transmission order is defined - by identifier and mailbox number). - - This creates situation when order frames are put in upper part of CAN - driver (via can_write) and order frames are sent on bus can be - different (and I experience this in wild). Since CAN driver API - pretends to be "file like" I expect data to be read from fd the same - order it is written. So I consider described behaviour to be a bug. - - I propose either to set TXFP bit in the CAN_MCR register (FIFO - transmit order) or to use only one mailbox (2017-10-19). - * The timer frequencies (BOARD_TIMx_FREQUENCY) are incorrectly defined - in configs/stm3240g-eval/include/board.h. Since the APB prescalers are - set to divide by 4 and 2 respectively, the frequencies should be - "2xAPBx" as said in the comment.  The correct frequencies are already - defined but as STM32_APBx_TIMx_CLKIN. From Mattias Edlund (2017-10-19). - * drivers/ioexpander: The IRQ subsystem now supports passing a void * - parameter to IRQ handlers. Use that method to support multiple pc9555 - devices, by passing a pointer to the device to the board defined irq - handler. Now the CONFIG_ for multiple PCA devices just allocates device - structures dynamically instead of statically when not enabled. - - The same interrupt handler is entered with the device structure - parameter in all situations, multiple or single PCA. One should still - be careful if multiple PCA devices share the same IRQ. From Sebastien - Lorquet (2017-10-19). - * libc/match: Use of exp() vs expf() in logf() caused function to be - slow. From Alan Carvalho de Assis (2017-10-19). - * drivrs/mtd/filemtd.c: add block device MTD interface. Block MTD - interface allows using block device directly as MTD instead of having to - use file-system in between. NOTE that this provides the opposite - capability of FTL which will let you use an MTD interface directly as a - block device. From Jussi Kivilinna (2017-10-19). - * There was a reference counting problem in the TPC logic of - net_clone(). net_clone() which is the common logic underlying dup() and - dup2() for sockets. When net_clone() calls net_start_monitor() and - net_start_monitor() returns a failure (because the underlying TCP - connection) then net_clone() must back out the reference count on the - structure. Problem noted by Pascal Speck and this implementation of the - solution is based on his suggestion (2017-10-19). - * There was a possible recursion that could eventually overflow the - stack. The error occurred when closing the socket with inet_close() - while a socket callback was still queued. When the socket callback was - executed by devif_conn_event(), this resulted in a call to - psock_send_eventhandler() with TCP_CLOSE flag set which then called - tcp_lost_connection(). tcp_shutdown_monitor() then called - tcp_callback() again, which again called psock_send_eventhandler(), and - so on.... Noted by Pascal Speck. Solution is also similar to a - solution proposed by Pascal Speck (2017-10-19). - * nucleo-f334r8/adc: change serial console to USART2 (STLINK COM). From - Mateusz Szafoni (2017-10-19). - * stm32f33xxx_adc.c: fix some warnings and compilation error when extsel - not in use. From Mateusz Szafoni (2017-10-19). - * net/tcp: Same change to tcp_send_buffered.c probably also applies to - tcp_send_unbuffered.c (2017-10-19). - * net/tcp: Same change to tcp_send_buffered.c probably also applies to - tcp_sendfile.c (2017-10-19). - * tcp_lost_connection() is called from two places in tcp_sendfile.c - (2017-10-19). - * net/tcp: Same change to tcp_send_buffered.c probably also applies to - sixlowpan_tcpsend.c and inet_recvfrom.c (2017-10-19). - * drivers/sensor: Add driver for the APDS-9960 gesture sensor. From - Alan Carvalho de Assis (2017-10-20). - * include/nuttx/sensors/ioctl: deduplicate SNIOC_CFGR. From Jussi - Kivilinna (2017-10-20). - * drivers/sensors/hts221: power-on sensor for loading calibration data. - From Jussi Kivilinna (2017-10-20). - * arch/arm/src/stm32f7/i2c: fix I2C_M_NORESTART handling. From Jussi - Kivilinna (2017-10-20). - * drivers/sensors/apds9960.c: Use work_queue to read/process data when - receive an IRQ. From Alan Carvalho de Assis (2017-10-20). - * STM32L1, STM32L4 RTC: add periodic interrupts, update L1 RTC - implementation - - STM32L4 RTC: add support experimental CONFIG_RTC_PERIODIC - - STM32 RTC: separate STM32L1 RTC into a separate file - STM32L1 RTC is very close to F4 or L4 versions, with two alarms and - periodic wakeup support so backported L4 peripheral to L1. - - RTC: Add periodic alarms to upper and lower halves - From Juha Niskanen (2017-10-20). - * stm32_adc.c: clear pending interrupts. From Mateusz Szafoni - (2017-10-20). - * drivers/bch: The character driver to block device access now supports - an IOCTL to get the geomtry of the underlying block device (2017-10-20). - * fs/fat: Remove mkfatfs from the OS. This is a user-space application - and belongs in apps, not in the OS (2017-10-20). - * configs/nucleo-f334r8: add logic for zero latency high priority - interrupts example. From Mateusz Szafoni (2017-10-22). - * Misc STM32 chagnes - - STM32 HRTIM: Fix warnings related with RCC - - STM32F33xxx ADC: Add some publicly visable interfaces and some - code to support injected channels - - STM32F33xxx DMA: Add public interface to handle with DMA interrupts - From Mateusz Szafoni (2017-10-22). - * stm32f103-minimum: Add an ADPS-9960 example configuration. From Alan - Carvalho de Assis (2017-10-23). - * net/icmp: This change adds support for semi-standard IPPROTO_ICMP - AF_INET datagram sockets. This replaces the old ad hoc, nonstandard way - of implementing ping with a more standard, socket interface (2017-10-23). - * net/inet: Add check for protocol before handing out TCP and UDP - sockets (2017-10-23). - * arch/arm/common/up_checkstack: fix assert panic when both TLS and - interrupt stack are enable. From Jussi Kivilinna (2017-10-23). - * net/icmp: Correct some comments, typings, spacing problems from last - big ICMP socket change (2017-10-23). - * configs/: All defconfig filess that include - CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and - deselect CONFIG_DISABLE_POLL (2017-10-24). - * net/icmpv6: This commit adds support for semi-standard IPPROTO_ICMP6 - sockets. This is a replacement for the non-standard ICMPv6 ping support - that violated the portable POSIX OS interface (2017-10-24). - * mm/mm-heap: memalign: fix heap corruption caused by using unaligned - chuck size. Unaligned nodes generated by memalign later cause heap - corruptions when nodes are shrink further (for example, 24 bytes -> 8 - bytes, when alignment is 16 bytes). From Jussi Kivilinna (2017-10-24). - * lm3s8962: NX configuration needs CONFIG_NXSTART_EXTERNINIT=y - (2017-10-24). - * sched/: move POSIX thread specific data from pthread TCB to common - TCB structure. This change allows using - pthread_getspecific/pthread_setspecific from main thread. Patch also - enables using pthread data with config option CONFIG_DISABLE_PTHREAD=y. - From Jussi Kivilinna (2017-10-25). - * net/local: fix typo in config macro name. From Juha Niskanen - (2017-10-25). - * Olimex stm32-h407 serial support for the on-board UEXT connector - (fixed style & defconfig). Add USART6 for UEXT connector. Add - nsh_uext configuration and README update. From Jan Pobříslo (2017-10-26). - * configs/nucleo-l496zg/nsh: enable I2C4 bus with i2ctool. From Jussi - Kivilinna (2017-10-26). - * arch/arm/stm32f7: i2c: restore bus frequency after I2C reset. Copy - frequency restoration fix from STM32L4 I2C driver to STM32F7 I2C - driver. From Jussi Kivilinna (2017-10-26). - * arch/stm32l4: port STM32F7 I2C driver to STM32L4. STM32L4 I2C driver - is in work-in-progress state (plentiful of TODOs and #warnings) and lags - many features found in more up-to-date STM32 I2C drivers. The peripheral - on STM32F7 and STM32L4 are identical except for L4's 'wakeup from stop - mode' flag and STM32F7's I2C driver is in more 'ready to use' state. - - Commit ports the STM32F7 I2C driver to STM32L4. The I2C clock - configuration is kept the same as before (I2CCLK = PCLK1 80 Mhz) - instead of switching to STM32F7 arch default that is I2CCLK=HSI. - Further work would be to add configuration option for choosing I2C - clock source instead of current hard-coded default. From Jussi - Kivilinna (2017-10-26). - * drivers/sensors/lis2dh: fixes for self-test. From Jussi Kivilinna - (2017-10-26). - * include/nuttx/fs/: Move prototype of foreach_mountpoint out of - include/nuttx/fs/fs.h to fs/mount/mount.h (2017-10-26). - * fs/mount: Implements procfs /proc/fs/blocks and /proc/fs/usage files, - replacing the NSH df command. Also implements procfs /proc/fs/mount - file, replacing the NSH mount command when there are no arguments - (2017-10-26). - * Correct a problem that was causing an apparent directory to be - reported as a file instead of a directory by opendir. This happened - after adding these three new procfs entries: fs/block, fs/mount, and - fs/usage. Of course, there is no directory fs in this case, only three - files that have fs/ in their relative pathnames. The logic was - detecting that fs was the name of the enty to report, but it was then - declaring that fs was a file (because fs/block is of type file). This - was fixed by adding a check for matching lenghts. i.e., if strlen(fs) - != strlen(fs/block), then report fs as a directory instead of a file - (2017-10-26). - * fs/procfs: Missing some conditional logic for cases where mountpoint - procfd entries excluded (2017-10-27). - * drivers/can/mcp2515.c: Fix the MCP2515 Bit Rate Prescale - calculation. Fix BRP for SET_BITTIMING ioctl as well. From Alan - Carvalho de Assis (2017-10-27). - * sensors/lis2dh: Fix use of obsolete dbg macro. From Jussi Kivilinna - (2017-10-27). - * nucleo-f334r8: Add highpri example configuration. From Mateusz - Szafoni (2017-10-28). - * STM32 F33xx: Add ADC DMA support to STM32F33 configuration. From - Mateusz Szafoni (2017-10-28). - * drivers/net: Remove the old, unfinished Crystal LAN driver. I don't - even have the hardware that it goes with anymore (2017-10-28). - * configs/mx1ads: This commit removes board support for the mx1ads - board. That board support was never completed and I no longer even have - the hardware. The unfinished board support is still available in the - Obsoleted repository if anyone would ever like to resurrect it - (2017-10-28). - * STM32 ADC: Added support for ADC's IO_ENABLE_TEMPER_VOLT_CH ioctl on - STM32F10XX and STM32F20XX. From Dmitriy Linikov (2017-10-30). - * STM32 F2: Fixed build for STM32F20XX platforms when - CONFIG_STM32_DMACAPABLE is enabled. From Dmitriy Linikov (2017-10-30). - * fs/userfs: This completes coding of the UserFS client and of the - UserFS feature in general. This feature is being merged to main now - because I believe it is innocuous. It is, however, untesed. The next - step will be to develop a test case to verify the feature. Uses Unix - domain local sockets instead of message queues. Easier to transfer big - data in local sockets than message queues (2017-10-30). - * Fix DEBUGASSERT() issues with nxhello on lc823450-xgevk - - sched/task: Remove DEBUGASSERT in task_exitstatus() and - task_groupexit() - - graphics: Change DEBUGASSERT condition in nx_runinstance() - From Masayuki Ishikawa (2017-10-31). - * Fix GPIO operation of STMPE811 driver. - 1. STMPE811_GPIO_DIR was defined for register name and later was - redefined to be the pin direction mask for `stmpe811_gpioconfig`. I - decided to change register name to be STMPE811_GPIO_DIR_REG, and keep - pin direction mask STMPE811_GPIO_DIR, so that any external code that - already use this driver will be unchanged. - 2. The STMPE811 register GPIO_DIR uses bit value 1 for output and 0 - for input, but `stmpe811_gpioconfig` set the opposite. - 3. The call to `stmpe811_gpiowrite` from inside of - `stmpe811_gpioconfig` leaded to deadlock. - From Dmitriy Linikov (2017-10-31). - * sim/userfs: Add a configuration for testing the UserFS using - apps/examples/userfs (2017-10-31). - * Fixes a memory leak that is caused because the client message queue is - not unlinked after the client disconnects from the NX server. From - Masayuki Ishikawa (2017-10-31). - * drivers/wireless/ieee80211: Fix typos and spelling errors as needed - for Photon build. From Anthony Merlino (2017-11-01). - * net/icmpv6: Add some header file necessary for correct build. From - Anthony Merlinoo (2017-11-01). - * libc/userfs: Correct return value from dispatchers. Should return - zero on success, not the number of bytes sent (2017-11-01). - * net/ipforward: Fixes typo that caused build error when IP forwarding - was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as well. From - Anthony Merlino (2017-11-01). - * ieee802154: Simplifies notify() and rxframe() calls to a single - notify() call. dataind's and all other "notifs" are now "primitives" - which aligns with standard terminology From Anthony Merlino (2017-11-01). - * fs/userfs: Correct check for response type (2017-11-01). - * net/local: This commit modifies the Unix domain local socket design. - Local sockets are built on top of pipes. The Local socket - implementation maintained file descriptors to interrupt with the pipes. - File descriptors have the bad property that they are valid only while - running on the thread within the task that created the local socket. - - As a policy, all internal OS implementations must use "detached" files - which are valid in any context and do not depend on the validity of a - file descriptor at any point in time. This commit converts the usage - of file descriptors to detached files throughout the local socket - implementation (2017-11-02). - * fs/userfs: There are some deadlock issues that make the UserFS - un-usable at the current time. Added to the TODO list; also feature is - now marked EXPERIMENTAL (2017-11-02). - * drivers/serial/serial.c: Optimize wait time in tcdram() for buffer - emptying. According to the specification, the close function must wait - until all data has been written before it closes the file (except - O_NONBLOCK is set). The maximum waiting time for this is not specified. - - To be able to edit the file list of the process, the close function - has to lock the file list semaphore. After that the close function of - the serial driver is called. - - Waiting for the complete transmission of all data is done in the - serial driver. This causes the semaphore to remain locked until all - data has been sent. However, no other thread of the process can edit - the file list for that time (open, close, dup2, etc.). This is not - optimal in a multithreaded environment. Therefore, we have to keep - the waiting time within the driver as short as possible. From Frank - Benkert (2017-11-02). - * drivers/loop: Don't use file descriptors... Use the internal file - system interfaces so that the loop device can be shared across threads - (2017-11-02). - * drivers/mtd/filemtd.c: Don't use file descriptors... Use the internal - file system interfaces so that the loop device can be shared across - threads (2017-11-02). - * mac802154: Fixes a warning for unused variable and returns -1 from - macnet_notify() if event is not used. From Anthony Merlino (2017-11-03). - * drivers/lcd/max7219.c: Add support to MAX7219 LED Matrix as LCD - interface. From Alan Carvalho de Assis (2017-11-04). - * configs/stm32f103-minimum: Add board support for MAX7219 LED Matrix - controller. From Alan Carvalho de Assis (2017-11-04). - * stm32f334-disco, nucleo-f334r8: add missing ram_vectors configuration - in linker script.

STM32 Fixes: - - STM32 HRTIM: add helper macros - - STM32F33xxx ADC: injected channels support, fix some definitions, - add interface to disable interrupts - From Mateusz Szafoni (2017-11-05). - * fs/userfs: This commit converts the underlying IPC used by the - UserFS from Unix domain local sockets to UDP LocalHost loopback - sockets. The problem with the local sockets is that they do require - operations on the top level pseudo-file system inode tree. That tree - must be locked during certain traversals such as enumerate mountpoints - or enumerating directory entries. - - This conversion is unfortunate in the sense that Unix local domain - sockets are relatively lightweight. LocalHost UDP sockets are much - heavier weight since they rely on the full UDP stack. If anyone is - up for a complete redesign, then using some shared memory and a POSIX - message queue would be lightweight again. - - This commit also fixes several bugs that were not testable before the - inode tree deadlock. I cannot say that the logic is 100% stable but - it does not have basic functionality (2017-11-05). - * fs/userfs: Fix return value from dup method. In order to return a - pointer, the parameter must be a pointer to a pointer (2017-11-06). - * configs/stm32f429i-disco/ltdc: This configuration has been deleted - because it violated the portable POSIX OS interface.

Add support - for power pin to SDMMC driver. In SDMMC driver, don't do DMA if the entire - transfer will fit in the FIFO. In SDMMC driver, add logic to transfer data - when TXDR or RXDR interrupts occur. Also, add logic to set the RX - watermark to 2 when receiving short, non-DMA data transfers. In SDMMC - driver, fix an error which was clobbering the interrupt mask register - (xfrmask). Also, add a kludge for the missing DTO interrupt. From Gregory - Nutt (2017-12-20). - * arch/arm/src/lc823450: Add SP_DMB() into lc823450_testset.c. In - lc823450, ldrex and strex are not supported. So we implemented up_testset() - with H/W Mutex. However, there was a bug in memory access order. This - change ensures correct memory access order in up_testset() for lc823450. - From Masatoshi.Tateishi (2017-12-21). - * sched/semaphore/spinlock.c: Add memory barrier operations in - spin_unlock(). In ARM document regarding memory barriers, SP_DMB() must be - issued before changing a spinlock state to SP_UNLOCKED.

DMA should not be enabled on non-DMA - transfers, the burst setting in FIFOTH is supposed to match the burst - setting in the BMOD reseters, Add DMA error interrupt support. With these - changes DMA now works on the LPC54xx. From Gregory Nutt (2017-12-21). - * fs/vfs: reopen should return NULL when oflags is less than 0, not equal - to 0. Because negative value is returned on failure of lib_mode2offlags - which converts the mode string into file open mode flag. From Gregory Nutt - (2017-12-21). - * tools/cvsparser.c: Add a check to avoid access past the end of a fixed - size array From Gregory Nutt (2017-12-21). - * arch/arm/src/arm/up_cache.S: Fix cp15_invalidate_dcache.

From Gregory Nutt - (2018-01-03). - * fs/vfs: Add support for truncate() and ftruncate(). The infrastructure - is complete. Now, however, the actual implementation of ftruncate() will - have to be done for each file. From Gregory Nutt (2018-01-04). - * fs/nxffs: Add partial implementation of the truncate method: It - extends files, but cannot yet shrink them. From Gregory Nutt (2018-01-04). - fs/smartfs: Add implementation of the truncate method, fs/fat: Add - implementation of the truncate method. fs/nfs: Add support for the - truncate method to the NFS file system. From Gregory Nutt (2018-01-04). - * net/route: Fix a couple of compile-related issues that have crept in - since the last time the file-based routing table was used.

Enable DVFS - in audio and RNDIS. Add telnet character mode to RNDIS. From Masayuki - Ishikawa (2018-01-10). - * arch/arm/src/samdl: In sam_spibus_initialize(), the pinmux configuration - was smashing the previous CTRLA register configuration. There are also some - typos in samd_spi.h From Matt Thompson (2018-01-11). - * SAMDL fix g_spi2ops and g_spi2dev using incorrect values From Matt - Thompson (2018-01-11). - * SAMD External Interrupt Controller (EIC) support From Matt Thompson - (2018-01-11). - * fs/procfs: Fix an error in a common function that manages read data. - From Gregory Nutt (2018-01-12). - * sched/irq: Add a configuration option to show interrupt information via - a procfs file. From Gregory Nutt (2018-01-12). - * arch/arm/src/lpc54xx: The SPI driver is code complete but still - untested. This driver is 'basic' in that in only supports polled mode - operations. From Gregory Nutt (2018-01-14). - * arch/arm/src/stm32/stm32_hrtim: fix deadtime configuration. Add - interface to change outputs SET/RST configuration From Mateusz Szafoni - (2018-01-14). - * drivers/loop/losetup.c: If we want to open read-only in losetup.c, flags - should be O_RDONLY not O_RDWR From Fabio D'Urso (2018-01-14). - * sched/clock/clock_systimer.c: Replace critical section APIs with - spinlock APIs. (64bit only). If SMP=n or SMP=y && SPINLOCK_IRQ=n, this - works in the same way as before. If SMP=y && SPINLOCK_IRQ=y, performance - will be improved. From Masayuki Ishikawa (2018-01-15). - * sched/clock/clock_systimer.c: Change the way that the 64-bit time is - sampled. Previously, we disabled interrupts before sampling the 64-bit - timer since the uint64_t access is not atomic on most CPUs. However, - disabling (local) interrupts does not work in the SMP case. In that case, - the timer interrupt will be running on only one of the CPUs; disabling - interrupts on a different CPU will provide no protection from timer - rollover. To work around this, logic was added that samples 64-bit timer - is sampled twice and if 32-bit rollover was detected between samples, then - loops until there is no rollover. From Gregory Nutt (2018-01-15). - * configs/nucleo-l432kc/src: Fix some bogus logic noted by Fanda. From - Gregory Nutt (2018-01-15). - * fs/smartfs: Fix inverted ifdef for CONFIG_SMARTFS_USE_SECTOR_BUFFER in - smartfs_extendfile() From Jussi Kivilinna (2018-01-16). - * configs/nucleo-* and configs/stm32l476vg-disco: Fix more - stm32_userleds.c bogus logic From Juha Niskanen (2018-01-16). - * Fixes two bugs in multi-block SD-card operations on the STM32F7 - platform. arch/arm/src/stm32f7: DBLOCKSIZE must be the size of SD-card - block, not the total amount of transferred bytes. drivers/mmcsd: respect - SDIO_CAPS_DMABEFOREWRITE on CMD25. From Evgeniy Bobkov (2018-01-16). - * Fixed nucleo-l432kc broken build when CONFIG_USERLED_LOWER defined From - Fanda (2018-01-16). - * Remove the BOARDIOC_TSCTEST_TEARDOWN boardctl() command. Remove all - implementations of board_tsc_teardown() (they were all stubs anyway except - for the simulation). From Gregory Nutt (2018-01-16). - * SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note(). These APIs - are used in sched_note.c to protect instrumentation data. The difference - between these APIs to exsiting spin_lock() and spin_unlock() is that they - do not perform instrumentation to avoid recursive call when - SCHED_INSTRUMENTATION_SPINLOCKS=y. From Masayuki Ishikawa (2018-01-17). - * configs: Eliminates the BOARDIOC_TSCTEST_SETUP command. Each board now - initializes the touchscreen controller as a normal part of its board - bring-up. board_tsc_setup() is gone; the touchscreen controller is now - treated like any other on-board device. - * configs: Since the touch screen initialization is now called from - one-time board-initialization logic, it no longer needs protection from - re-entry. From Gregory Nutt (2018-01-17). - * configs: CONFIG_MAX_TASKS must be a power of 2. From Gregory Nutt - (2018-01-17). - * configs: There should be either CONFIG_LIB_BOARDCTL=y or - CONFIG_BOARD_INITIALIZE=y (but not both) in the defconfig of every - standalone NxWM configuration to assure that all of the board resources are - initialized... especially the touchscreen since it is now a part of the - board driver initialization. From Gregory Nutt (2018-01-17). - * arch/arm/src/samdl: SPI must be disabled before changing the mode bits in - CTRLA register From Matt Thompson (2018-01-17). - * arch/arm/src/lc823450: Explicitly assign I2S IRQ handling to CPU0. From - Masayuki Ishikawa (2018-01-18). - * drivers/input/ft5x06.c: Remove logic to disable polling when there there - is no client waiting for read data. That was a great idea to save CPU - cycles when there is nothing reading from the touchscrren but, - unfortunately, does not work with readers that open the driver in - non-blocking mode. So I think we just have to eat the CPUs even when there - is nothing waiting for touchscreen input. From Gregory Nutt (2018-01-18). - * configs/lpcxpresso-lpc54628/lvgl: Add LittlevGL graphics demo - configuration. From Gregory Nutt (2018-01-18). - * sched/semaphore: Add DEBUGPANIC() in nxsem_post() if no waiting task is - found.

From David Alessio (2018-01-22). - * net/: The existence of the network driver ioctl() method should depend on - CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former - enables the method, the later enables a subset of possible driver IOCTLs. - This change should be basically a no-operation. The affected ioctl methods - only support those subset of driver IOCTLs selected by - CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl - method. From Gregory Nutt (2018-01-22). - * net/tcp: Write buffering logic should not wait for a free buffer if the - socket was opened non-blocking. Also, rename the TCP write buffering - macros from WRB_* to TCPWB_* to make room in the namespace for write - buffering with other protocols. From Gregory Nutt (2018-01-22). - * net/udp: Remove some conditional logic that was true if there is only a - single network device, but not true in the multi-device context. From - Gregory Nutt (2018-01-22). - * net/udp: This commit adds an implementation of UDP write buffering. - From Gregory Nutt (2018-01-22). - * net/udp: In sendto(), return EHOSTUNREACH if the network is down.

Unlike the F1, these parts do not have a separate BKP address - region. The BKP registers are with the RTCC address regions. stm32_bkp.h - should only be used for STM32 F1. stm32_rtcc.h should be used to access BKP - registers on F2, F3, and F4. From Gregory Nutt (2018-01-26). - * stm32/Kconfig: fix COMP7 dependency. stm32_hrtim: add HRTIM push-pull - mode configuration. stm32f334-disco: add buck-boost converter mode From - raiden00pl (2018-01-27). - * arch/arm/src/samdl: Added Analog Comparator headers and basic - initialization From Matt Thompson (2018-01-28). - * arch/arm/src/stm32: I have a SPI bus with both Mode 0 and Mode 3 devices - on it. After performing SPI I/O to a Mode 0 device, switching to a Mode 3 - device locked up the SPI interface. Only zeroes would be read. I traced - the reason for the lock-up to arm/arm/src/stm32f7/stm32_spi.c function - spi_setmode(). Changing the mode causes a spurious SPI clock transmission - that confuses the stm32f7 SPI input hardware. This problem is solved by - (1) changing the SPI mode with SPI (and perhaps DMA) disabled, and (2) - flushing the receive FIFO if the mode change results in garbage in the - FIFO. From Bob Feretich (2018-01-29). - * drivers/sensors: Add support to MAX44009 ambient light sensor From Juha - Niskanen (2018-01-29). - * tools/logparser: Add a tool which (when it matures) will help me to - convert git logs to ChangeLog format. From Gregory Nutt (2018-01-29). - * tools/: Add #define _GNU_SOURCE to all C files that call asprintf() - From Gregory Nutt (2018-01-29). - * arch/arm/src/samdl: Added Timer Compare for Control registers header - From Matt Thompson (2018-01-29). - * sched/sched: Add new internal OS function nxsched_setaffinity() that is - identical to sched_isetaffinity() except that it does not modify the errno - value. All usage of sched_setaffinity() within the OS is replaced with - nxsched_setaffinity(). From Gregory Nutt (2018-01-30). - * sched/sched: Internal functions sched_reprioritize() and - sched_setpriority() no longer modify the errno value. Also renamed to - nxsched_reprioritize() and sched_setpriority(). From Gregory Nutt - (2018-01-30). - * sched/sched: Add new internal OS function nxsched_getscheduler() that is - identical to sched_getscheduler() except that it does not modify the errno - value. All usage of sched_getscheduler() within the OS is replaced with - nxsched_getscheduler(). From Gregory Nutt (2018-01-30). - * sched/sched: Add new internal OS function nxsched_setparam() that is - identical to sched_setparam() except that it does not modify the errno - value. All usage of sched_setparam() within the OS is replaced with - nxsched_setparam(). From Gregory Nutt (2018-01-30). - * sched/sched: Add new internal OS function nxsched_getparam() that is - identical to sched_getparam() except that it does not modify the errno - value (actually, the previous value erroneously neglected to set the errno - value to begin with, but this fixes both issues). All usage of - sched_getparam() within the OS is replaced with nxsched_getparam(). From - Gregory Nutt (2018-01-30). - * sched/: Fix several inappropriate accesses to get_errno() that were - missed in previous changes (some going back to nuttx-.23). Add new - nxsched_setscheduler() and nxsched_getaffinity() which are equivalent to - their counterparts without the nx on front. These versions do not modify - the errno value. Changed all calls within the OS to use these newer - versions of the functions. From Gregory Nutt (2018-01-30). - * binfmt/, configs/, grahics/, libc/, mm/, net/, sched/: OS references to - the errno variable should always use the set_errno(), get_errno() macros. - From Gregory Nutt (2018-01-30). - * arch/arm/src/stm32 and stm32f7: Architecture-specific code is not - permitted to modify the errno variable. drivers/ and libc/: OS references - to the errno variable should always use the set_errno(), get_errno() - macros. From Gregory Nutt (2018-01-30). - * SMP: Introduce a new global IRQ clearing logic and tasklist protection. - The previous implementation of clearing global IRQ in sched_addreadytorun() - and sched_removereadytorun() was done too early. As a result, nxsem_post() - would have a chance to enter the critical section even nxsem_wait() is - still not in blocked state. This patch moves clearing global IRQ controls - from sched_addreadytorun() and sched_removereadytorun() to - sched_resumescheduler() to ensure that nxsem_post() can enter the critical - section correctly. For this change, sched_resumescheduler.c is always - necessary for SMP configuration. In addition, by this change, task_exit() - had to be modified so that it calls sched_resumescheduler() because it - calls sched_removescheduler() inside the function, otherwise it will cause - a deadlock. However, I encountered another DEBUGASSERT() in - sched_cpu_select() during HTTP streaming aging test on lc823450-xgevk. - Actually sched_cpu_select() accesses the g_assignedtasks which might be - changed by another CPU. Similarly, other tasklists might be modified - simultaneously if both CPUs are executing scheduling logic. To avoid this, - I introduced tasklist protetion APIs. With these changes, SMP kernel - stability has been much improved. From Masayuki Ishikawa (2018-01-31). - * arch/arm/src/samdl: Added I2S register definitions. From Matt Thompson - (2018-01-31). - * drivers/sensors/lis2dh: Use realtime clock if monotonic is not - available From Juha Niskanen (2018-01-31). - * fs/aio: Fix one additional place where the errno variable is being - accessed inappropriately. From Gregory Nutt (2018-01-31). - * sched/wdog: wd_start() is an internal OS function and should not set the - errno value. Reviewed and updated every call to wd_start() to verify if - return value is used and if so if the errno value is accessed. From - Gregory Nutt (2018-01-31). - * sched/task: Add nxtask_create(). Kthread_create() and nxtask_create() - are internal OS functions and should not modify the errno variable. - configs/: threads started by board bringup logic should be kernel threads, - not user tasks. From Gregory Nutt (2018-01-31). - * drivers/: threads started by drivers should be kernel threads, not user - tasks. Review return values for all calls to kthread_start() because it no - longer returns an errno. From Gregory Nutt (2018-01-31). - * graphics/: Review return values for all calls to kthread_start() because - it no longer returns an errno. From Gregory Nutt (2018-01-31). - * sched/: Convert legitimate uses of task_create() to nxtask_create(). - Review handling of returned values from all uses of kthread_create() (as - well as nxtask_create()). From Gregory Nutt (2018-01-31). - * arm/src/kinetis: Correct some Ethernet PHY register bit tests for the - KSZ8081 PHY. From Stewart (2018-02-01). - * libc/stdio: in dtoa(), up_interrupt_context() is used in a debug - assertion. up_interrupt_context() is not available in the user-mode phase - of the PROTECTED or KERNEL build configurations. In those configurations, - enabling libc floating point support and debug assertions will result in an - undefined reference to up_interrupt_context(). From Gregory Nutt - (2018-02-01). - * binfmt/: Fix one more inappropriate access to the errno variable. From - Gregory Nutt (2018-02-01). - * configs/stm32f103-minimum: Add support to BMP180 on BluePill - (stm32f103-minimum) board. From Alan Carvalho de Assis (2018-02-04). - * armv7-a, armv7-r, armv7-m: Add atomic read-add-write and - read-subtract-write functions. From Gregory Nutt (2018-02-04). - * spin_lock_irqsave() and spin_unlock_irqrestore() are only valid if the - CPU supports global disabling of interrupts. From Gregory Nutt (2018-02-04). - * sched/sched: SMP: Fix this_task() to be an atomic operation. In the - previous implementation, this_task() was defined in sched.h by using just a - macro current_task(this_cpu()). However, I found that this is not atomic - and actually sometimes switching CPU happened in executing the macro when - we tested audio steaming plus executing commands via telnet. This change - resolves this issue by implementing atomic this_task()in sched_thistask.c - which is newly introduced. From Masayuki Ishikawa (2018-02-04). - * configs/stm32f429i-disco: Separate SPI4 from MTD init. I was trying to - attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4 port - and was hitting compilation problems, since CONFIG_MTD and thus 'struct - mtd_geometry_s' was not defined. This patch separates SPI4 initialization - logic from MTD initialization logic. From Michael Jung (2018-02-05). - * sched/sched: Implements a global scheduler lock capability as part of - SMP support. This allows the scheduler to be locked with no knowledge or - access to the TCB of the currently running task. This is necessary because - accessing the TCB of the currently running task is, itself, a non-atomic - operation. This global scheduler lock capability was add just to support - that atomic access to the TCB. From Gregory Nutt (2018-02-05). - * sched/sched: Extend the last global lock change to work with the - lc823450-xgevk which does not support the atomic fetch add but does support - disabling interprocessor interrupts. Disabling interprocessor interrupts - will also guarantee that the TCB address calculation is atomic. From - Gregory Nutt (2018-02-05). - * sched/irq: Fix a infinite recursion problem that a recent change - introduced into the i.MX6 SMP implementation. From Gregory Nutt - (2018-02-06). - * arch/arm/src/armv7-a: Found some additional places were the new - this_task() function cannot be called in the i.MX6 SMP configuration. From - Gregory Nutt (2018-02-06). - * sched/ and arch/arm/src/armv7-a: Replace a few more occurrences of - this_task() with current_task(cpu) in an effort to get the i.MX6 working in - SMP mode again. It does not yet work, sadly. From Gregory Nutt - (2018-02-06). - * sched/task: It is not appropriate for logic in task_exit() to call the - new version of this_task(). sched/irq: Remove redundant fetch of CPU - index; configs/sabre-6quad: update README. From Gregory Nutt (2018-02-06). - * arch/arm/src/lpc17xx: Disable LPC17 FDR when not used. If a boot loader - set the fractional divider (FDR) the baud rate in nuttx will be wrong - (multiplied by this fraction). So if it is not used, it should be - disabled. From hg42 (2018-02-08). - * arch/mips/src/mips32: In up_idle, the kludge that was conditionally - enabled if the work queue was enable appears to be needed even when he work - queue is not enabled on the PIC32MZ. - * arch/mips/src/pic32mz: Fix some typos in debug instrumentation in - pic32mz-gpio.c; fix some typos related to UART5 configuration in - pic32mz-serial.c. - * configs/flipnclick-pic32mz/nsh: Switch serial console to UART3. There - is some problem with the UART4 RX pin documentation or configuration. From - Gregory Nutt (2018-02-09). - * arch/arm/src/xmc4/: Fix USIC_BRG_SCLKCFG definition From Alan Carvalho - de Assis (2018-02-09). - * drivers/lcd: Add configuration support for HiletGo OLED. - configs/flipnclick-pic32mz: Add board support for HiletGo OLED. From - Gregory Nutt (2018-02-10). - * configs/flipnclick-pic32mz: Add an nxlines configuration for use in - testing the custom HiletGo Click board.

From Matt Thompson (2018-02-10). - * arch/arm/src/samdl: Fix EIC interrupt edge sensitivity for pin numbers > - 8 From Matt Thompson (2018-02-10). - * arch/arm/src/samdl: Added loading factory USB calibration data from - NVRAM From Matt Thompson (2018-02-11). - * arch/arm/src/stm32/stm32_hritm: Add interface to set timer frequency, - fix slave timers reset configuration, change POWER_INFO to TIMER_INFO From - Mateusz Szafoni (2018-02-11). - * configs/stm32f103-minimum: Add zerocross support to STM32F103-Minimum - board From Alan Carvalho de Assis (2018-02-11). - * configs/flipnclick-sam3x: Adds basic board support for the HiletGo - OLED. From Gregory Nutt (2018-02-11). - * arch/arm/src/lpc17xx: DisableDisable LPC17 FDR when not used (second - fix). If a boot loader sets the fractional divider (FDR) the baud rate - in nuttx will be wrong (multiplied by this fraction). This also has to - be added to lpc17_lowputc.c. From Harald Gutsche (2018-02-11). - * arch/arm/src/samdl: Fix DMA controller support. From Matt Thompson - (2018-02-11). - * arch/arm/src/samdl: Added experimental DMA support to SPI driver. - spi_exchange() uses a pair of DMA channels for TX and RX. From Matt - Thompson (2018-02-11). - * configs/stm32f103-minimum: Add OLED SSD1306 support to - STM332F103-Minimum From Alan Carvalho de Assis (2018-02-11). - * drivers/lcd: Fix the default I2C address of SSD1306 OLED display (7- vs - 8-bit addressing) From Alan Carvalho de Assis (2018-02-11). - * net/tcp: Fixed bad return value handling in psock_tcp_send(). send() - expects psock_tcp_send() to return a negated errno value, not -1 with the - errno set (GN: I added same change for tcp_send_buffered.c which has the - same issue as tcp_send_unbuffered.c) From Pelle Windestam (2018-02-13). - * arm/arm/src/stm32: Corrections to STM32 F4 I2C to restore - functionality. From Alexander Oryshchenko (2018-02-13). - * arm/arm/src/stm32: Corrections to STM32 F4 I2C to fix the NORESTART - flag. From Alexander Oryshchenko (2018-02-13). - * drivers/sensors: Added support for LIS3DH accelerometer sensor.

This change - prevents from a deadlock in up_schedulesigaction.c where inter-CPU signal - handling is actually implemented. arch/arm/src/armv7-m: Fix signal - handling for SMP. In previous implementation, signal handling for SMP was - incorrect. Thus, for example, if an inter-CPU signal happened an incorrect - tcb was signaled and caused ASSERT(). This change fixes the issues and - works for both inter-CPU signal handling and signal handling on the same - CPU. From Masayuki Ishikawa (2018-02-14). - * arch/arm/src/armv7-a: Port the SMP change by Masayuki Ishikawa to the - ARMv7-A family. From Gregory Nutt (2018-02-14). - * arch/xtensa/common: Port the SMP change by Masayuki Ishikawa to the - Xtensa family. From Gregory Nutt (2018-02-14). - * configs/stm32f103-minimum: Remove CONFIG_NX_LCDDRIVER dependence from - stm32_ssd1306.c From Alan Carvalho de Assis (2018-02-14). - * drivers//sensors: LIS3DH: Fix missing shift when writing output data - rate to register From Matt Thompson (2018-02-14). - * sched/clock: Replace critical section APIs with spin lock APIs in - clock_gettime.c. This change will improve performance for SMP systems but - nothing changes for non-SMP systems. In SMP mode, rtrtcb is not always at - the g_readytorun.head. This change removes DEBUGASSERT() to avoid this - condition. From Masayuki Ishikawa (2018-02-15). - * drivers/lcd: lcd_framebuffer.c does not need to include board-specific - board.h. From Gregory Nutt (2018-02-15). - * include/lcd: Eliminate a warning from an SSD1306 header file by adding a - forward reference to struct i2c_master_s.

If this - operation is not done or done after PLL configuration, the STM32 fail to - continue boot operation if the frequency if greater than 24MHz according to - the board variable STM32_SYSCLK_FREQUENCY. Tested on stm32f334-disco - board. From Gwenhael Goavec-Merou (2018-02-17). - * configs/stm32f746g-disco: Add stm32f746g-disco Ethernet configuration. - Add USART1 support (connected to the USB virtual serial port) From Louis - Mayencourt (2018-02-19). - * drivers/mtd: mtd_config.c: Add still more error handling (to detect bad - underlying flash implementations).

In previous - commit, I2S IRQ might be sometimes assigned to CPU1 when CONFIG_SMP=y. - This change fixes this issue. Refactor timer driver. Introduce - lc823450_timer.h and move lc823450_timerisr.c to lc823450_timer.c Add MTM - timer APIs for DVFS. Introduce up_rtc_gettime() for CONFIG_RTC_HIRES. - Introduce idle time calculation in DVFS. Also, DVFS autonomous mode based - on CPU idle time is supported. NOTE: voltage control is still disabled. - From Masayuki Ishikawa (2018-02-23). - * configs/lc823450-xgevk: Update defconfigs. Enable RTC_HIRES instead of - RTC_DATETIME (audio/rndis).

From Gregory Nutt (2018-02-24). - * Fixed parsing of DNS response packets having compressed names ending with - pointer. There were troubles parsing response packets which have - compression of QNAME/NAME field when only trailing part of the name (not - the whole name) is replaced with pointer to another part of the packet. - This commit fixes parsing of such packets. Also I added checks to keep - parsing only in bounds of the read part of DNS response packet. From - Dmitriy Linikov (2018-02-26). - * arch/arm/src/stm32f7: Backport RTC alarm setting changes from STM32L4. - Most notably this fixes RTC getting stuck issue when both alarms were used. - Root cause was writing RTC ISR register contents to RTC CR register.

From Gregory Nutt (2018-03-16). - * fs/craomfs: Add CROMFS file system. CROMFS is a commpressed, in-memory - read-only file system based on LZF. From Gregory Nutt (2018-03-19). - * sched/sched: Fix a deadlock in SMP mode. Two months ago, I introduced - sched_tasklist_lock() and sched_tasklist_unlock() to protect tasklists in - SMP mode. This change works well for HTTP audio streaming aging test with - lc823450-xgevk. However, I found a deadlock in the scheduler when I tried - similar aging tests with DVFS autonomous mode where CPU clock speed - changed based on cpu load. In this case, call sequences were as follows. - To avoid this deadlock, I added sched_tasklist_unlock() when calling - up_cpu_pause() and sched_addreadytorun(). Also, added - sched_tasklist_lock() after the call. Also added critical sections to - lib_filesem.c, mm_sem.c, and net_lock.c for SMP for SMP.

From Juha - Niskanen (2018-03-22). - * i2c/i2c_master.h: Change incorrect comment about I2C_TRANSFER return - value to indicate that the method returns zero on success rather than the - number of bytes transferred. From Juha Niskanen (2018-03-22). - * configs/: Remove configurations using canutils/libuavcan and - examples/uavcan. libuavcan has not built for a year or so. The basic - problem is that as NuttX advances, the old frozen version of libuavcan has - become absolute because it violates the portable POSIX OS interface. No - one is maintaining the port so there is no alternative but to remove it. - From Gregory Nutt (2018-03-23). - * STM32, STM32L4: Add one bit read and write to 1-wire interface. This is - needed for devices that require single bit timeslot generation and for - 1-Wire search algorithm triplets.

From Janne Rosberg (2018-03-26). - * Per Matias Edlund: I recently used the tcflush function and found that it - failed with ENOTTY. The reason is that the TCFLSH case in the function - uart_ioctl in the file drivers/serial/serial.c does not update the ret - value." On success, the TCFLSH IOCTL logic needs to explicitly set the - return value (ret) to zero. From Gregory Nutt (2018-03-26). - * netdb: Fix boundary conditions in dns_recv_response(). Fix typos in - include/nuttx/net/dns.h From Masayuki Ishikawa (2018-03-27). - * configs/nrf52-pca10040: Add support for the NRF52-PCA10040 board - including LEDs and buttons From Janne Rosberg (2018-03-27). - * arch/arm/src/stm32: In case of PHY failure, usually because of the lack - of 25/50 MHz REFCLK input, the Ethernet block would lock up in a while - loop waiting for readiness, which will never happened. This prevented the - board from starting at all in the case of a PHY failure. This commit adds - a retry loop to avoid bricking the board if the Ethernet block is unable - to start. From Sebastien Lorquet (2018-03-27). - * mac802154: Adds basic support for RX-ENABLE.request primitive From - Anthony Merlino (2018-03-28). - * mac802154: Adds ackreq flag to TX descriptor for use by radio driver. The - radio layer is responsible for a full "transaction". Because of - differences in radio capabilities, the radio must be responsible for the - handling of acks and retransmissions. This commit simply passes the ackreq - meta-data flag along to the radio. Also Fixes bug where primitive was - freed when it shouldn't have been, causing double free call. From Anthony - Merlino (2018-03-28). - * wireless/bluetooth: Bring in the Bluetooth stack from the Intel/Zephyr - arduino101_firmware_source-v1.tar package. - * drivers/bluetooth: Adds re-architected version of the Bluetooth UART - driver from the Intel/Zephyr arduino101_firmware_source-v1.tar package. - From Gregory Nutt (2018-03-29). - * wireless/bluetooth and include/nutt/net: Add support for Bluetooth IOCTL - commands.

From Gregory Nutt (2018-04-11) Updated, corrected, and verified. - From Bob Feretich (2018-04-11). - * tools/nxstyle.c;: Add check for blank lines before and after single line - comments. From Bob Feretich (2018-04-11). - * arch/arm/src/: Problem: stm32f30xx hangs waiting for LSE to initialize. - Reason for hang is that operation of setting LSE_ON does not take effect - because there is no clock on PWR peripheral. this is initialized later in - the code From Michał Łyszczek (2018-04-11). - * arch/arm/src/imxrt: Brings in basic support for the i.MX RT 1050 - 'crossover' SoC. Includes timer and UART support. This port was the - joint effort of Janne Rosberg, Ivan Ucherdzhiev, and myself. I give - credit to Ivan for the kill because he is the one to held on to the end. - From Ivan Ucherdzhiev (2018-04-12). - * sched/sched: Change ordering of round-robin time slice check - (sched_process_scheduler()) and processing of wdog timers (wd_timer()). - wd_timer()'s callback function can change current running task and, hence, - must be done after the time slice check. The time slice check will - decrement the currently running task's time slice allotment. If such a - context switch occurs, then the newly started task will lost one could of - that allotment before it even has a chance to run. From EunBong Song - (2018-04-13). - * arch/arm/src/stm32: Adds a Bluetooth HCI UART lower half driver for the - STM32.

Reason is that size in bytes - is calculated always on uint32_t types and cards bigger than 4GB will - overflow uint32_t type. Solution is to use uint64_t where possible. From - Michał Łyszczek (2018-04-14). - * tools/mkromfsimg.sh: Include an option in mkromfsimg.sh to ignore - FAT/RAMDISK. This permits you to build tiny systems with ROMFS but with - the rather large FAT FS support.

From Dmitry Sharihin (2018-04-19). - * drivers/net: Add TAP (network bridge) mode to tun.c. In previous - implementation, TAP mode did not handle a packet correctly. Also, the - driver did not set the link layer type and could not assign the interface - name. This change fixes such issues and supports TAP mode correctly. From - Masayuki Ishikawa (2018-04-20). - * arch/arm/src/nrf52: Add watchdog timer drivers. Includes significant - updates from Alan Carvalho de Assis From Levin Li - (2018-04-20). - * configs/nrf52-pca10040: Add support for starting the watchdog timer on - the nRF52.

The NuttX - convention is that all internal functions that return errors as an 'int' - must return a negated errno value on failure and a non-negative value on - success. Most were right but eight of them had cloned logic that returns - 1 on success and zero on failure... both of which are interpreted as - success by the caller since they are non-negative. From Gregory Nutt - (2018-04-21). - * Makefile: Add support for nconfig frontend for 'make nconfig' From Michał - Łyszczek (2018-04-22). - * arch/arm/sc/lpc17xx: Freeing endpoints should be set the same allocations - as when endpoint was allocated.

Unlike most other unlink - implementations in NuttX drivers, this one does not allow any I2C - operations after unlink, making it possible to deallocate the I2C bus. - From Juha Niskanen (2018-04-24). - * configs/ stm32f746g-disco. Add clang support to stm32f746g-disco board - From Goran Mekić (2018-04-24). - * net/udp: Fix several issues using connected UDP sockets: sendto() should - not accept an address. Normally send() should be used with connect UDP - sockets instead. recvfrom() is no longer necessary. recvfrom() and - poll() should not reset to accept any addresses but should, instead, only - accept inputs and events from the connected remote peer. On of these - issues was noted by 李桂丁 . Changes were made as - summarized here: - http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch08lev1sec11.html - From Gregory Nutt (2018-04-25). - * include/nuttx/wireless: Add a setbaud() method to the HCI UART lower half - interface that can be used to change the default BAUD selection. - arch/arm/src/stm32: Implement the setbaud() method for the STM32 HCI - UART.

Add - support to handle connected UDP sockets. The correct 'optimal blksize' to - return is the MSS. The MTU is always too big. From Gregory Nutt - (2018-04-27). - * arch/arm/src/imxrt: Add IOMUX implemention for GPIO5. From Jake - (2018-04-27). - * net/udp: Remove an unused variable warning. Add some comments. From - Gregory Nutt (2018-04-27). - * arch/arm/src/kinetis: USB device fixes: Use correct CONFIG OTG control, - Fix interrupt storm when cable is disconnected. The DM, DP state were - incorrect because the pulldowns were not enabled. Also the pending - asynchronous resume interrupt needed to be re-armed after the suspend is - in effect.

Now, Makefile.unix will force LC_ALL=C just - for the sort command so that we can all generate equivalent defconfig - files. From Gregory Nutt (2018-04-29). - * arch/arm/src/tiva: Implements an EEPROM driver in compliance with MTD - driver as provided by NUTTX for TM4C1294. The EEPROM driver currently - supports only two functionalities - read bytes(multiple of 4) and write - bytes (multiple of 4). From Shirshak Sengupta (2018-04-29). - * arch/arm/src/tiva: Implemented Flash CONFIG_MTD_BYTE_WRITE for TM4c1294. - Implemented the tiva_write function which will write an arbitrary number - of bytes to flash (in multiple of 4). From Shirshak Sengupta (2018-04-29). - * progmem interface: Discern r/w and erase page sizes. Introduce new - up_progmem_erasesize architecture API to be able to communicate the - read/write page size independently from erase page size. Implement - up_progmem_erasesize for all architectures that already support progmem, - assuming that for those architectures the sizes of both read/write and - erase pages are identical. From Michael Jung (2018-05-01). - * arch/arm/src/include/kinetis and src/kinetis: Add architecture support - for the Kinetis K28F. From Gregory Nutt (2018-05-01). - * arch/arm/src/imxrt: This commit fixes more issues with the i.MX RT GPIO - IRQ. Add check for interrupt mask register before dispatching ISR.

Adds support for the Kinetis Freedom-K28F board. - From Gregory Nutt (2018-05-02). - * fs/nfs/rpc_clnt.c: Commit 091e3f7 broke the NFS client. sendto() can - (correctly) no longer be used with a connected UDP socket. In that case, - send() must be used instead. From Michael Jung (2018-05-02). - * drivers/rgbled: Adds support for multichannel PWM (multiple PWM channels - on a single timer) From Anthony Merlino (2018-05-02). - * drivers/sensors: Adds support for INA3221 power sensor.

From Gregory Nutt (2018-05-05). - * arch/arm/src/lpc17xx: Add support for ARMv7-M run time stack checking on - NXP LPC17xx MCUs based on CONFIG_ARMV7M_STACKCHECK. Basically copied from - stm32. From Michael Jung (2018-05-06). - * arch/arm/src: All ARM and MIPS architectures now support - CONFIG_ARCH_IDLE_CUSTOM From Gregory Nutt (2018-05-07). - * drivers/mtd/mtd_config.c: mtdconfig_register() returned OK instead of - -ENOMEM on failed malloc From Michał Łyszczek (2018-05-08). - * configs/teensy-3.x/usbnsh: Remove CONFIG_USBDEV_DUALSPEED from - configuration. Hardware supports only FS. From Gregory Nutt (2018-05-09). - * libc/unistd: Initial, minimal implementation of sysconf(). Only - sufficient to support the functionality of less standard - getdtabilesize(). From Michael Jung (2018-05-10). - * Documentation/NuttShell.html: Document the mkfatfs the -r option which - can be used to specify the number of entries in the FAT12/FAT16 root - directory. From Gregory Nutt (2018-05-11). - * LibTargets.mk, tools/Config.mk: Drop executable bit on installed - libraries. The rules to install libraries under lib/ were modified to use - mode 0644 instead of the default 0755. From Andrey Zabolotnyi (2018-05-12). - * arch/arm/src/stm32: Add internal pull-up option for SDIO pins (also picks - up an unrelated change to a README.txt file) From Alan Carvalho de Assis - (2018-05-12). - * arch/arm/src/kinetis + SDHC configs: Make Kinetis SDHC pullups work the - same as the STM32 SDIO pullups From Gregory Nutt (2018-05-12). - * net/udp: Resolve race condition in connection-less UDP sockets with - read-ahead buffering. In connection-mode UDP sockets, a remote address is - retained in the UDP connection structure. This determines both there - send() will send the packets and which packets recv() will accept. This - same mechanism is used for connection-less UDP sendto: A temporary remote - address is written into the connection structure to support the sendto() - operation. That address persists until the next recvfrom() when it is - reset to accept any address. When UDP read-ahead buffering is enabled, - however, that means that the old, invalid remote address can be left in - the connection structure for some time. This can cause read-ahead buffer - to fail, dropping UDP packets. Shortening the time between when he remote - address is reset (i.e., immediately after the sendto() completes) is not a - solution, that does not eliminate the race condition; in only makes it - smaller. With this change, a flag was added to the connection structure - to indicate if the UDP socket is in connection mode or if it is - connection-less. This change effects only UDP receive operations: The - remote address in the UDP connection is always ignored if the UDP socket - is not in connection-mode. No for connection-mode sockets, that remote - address behaves as before. But for connection-less sockets, it is only - used by sendto(). From Gregory Nutt (2018-05-13). - * include/sys: Add resource.h From Gregory Nutt (2018-05-13). - * rgbled: Fixes led issues caused by uninitialized memory with - CONFIG_RGBLED_MULTICHAN. The uninitialized pwm_info_s struct caused a - rogue channel to be started causing errors in the pwm driver From Anthony - Merlino (2018-05-14). - * arch/arm/src/imxrt/chip: Add pin multiplexing header files. From Gregory - Nutt (2018-05-14). - * configs/nucleo-l452re: Add buttons example From Juha Niskanen - (2018-05-15). - * arch/arm/src/imxrt/imxrt_serial.c: Fix some interrupt instabilities; must - be in a critical section when modifying serial interrupts. - configs/imxrt1050-evk/nsh/defconfig: Use the BASEPRI register to - enable/disable interrupts; enable the PROCFS file system. From Gregory - Nutt (2018-05-15). - * arch/arm/src/imxrt: Add missing support for the Cortex-M7 caches; - configs/imxrt1050-evk: Enable I- and D-Caches in the nsh configuration. - Calibrate the delay loop. Add support for the on-board LED. From Gregory - Nutt (2018-05-15). - * arch/arm/src/imxrt: Corrects some IOMUX controls. From Jake Choy - (2018-05-15). - * net/sixlowpan: Preserve big-endian (network order) when uncompressing - address. From Anthony Merlino (2018-05-15). - * arch/arm/src/imxrt/chip: Add DMA channel assignments. From Gregory Nutt - (2018-05-15). - * arch/arm/src/stm32f7: Add support for the second SDMMC device. The - second SDMMC device was already supported but the clock was never - enabled. This fixes that. From William Douglas (2018-05-15). - * arch/arm/src/imxrt: Add eDMA support (unverified). From Gregory Nutt - (2018-05-16). - * net/sixlowpan: TCP send should have PSH and ACK flags set when sending. - This matches the standard network (Ethernet) TCP send logic. From Anthony - Merlino (2018-05-17). - * net/udp: Recent changes to UDP in order to correct problems with UDP - connection mode introduced a new bug: The 'to' address passed to sendto() - must now be NULL in connection mode. But there are errors because there - was one place where the 'to' address was still being used. This commit - adds logic to first check for UDP connection mode. If the UDP socket is - connected, then the NULL 'to' address is ignored and saved connection - address is used instead. From Gregory Nutt (2018-05-17). - * arch/arm/src/stm32: Added Vbat measurement to adc driver for STM32F20xx - and STM32F4xxx. As with the MCU temperature and VREFINT measurement, this - change requires user to enable the corresponding channel first. For Vbat - channel the ioctl cmd is IO_ENABLE_DISABLE_VBAT_CH, and its arg should be - a pointer to bool which must be true to enable and false to disable the - Vbat channel. Moreover, since Vbat input contains a built-in voltage - divider, it is highly suggested to disable Vbat input channel after - measurement is done in order to prevent battery drain through the - divider. From Dmitriy Linikov (2018-05-18). - * configs/stm32l1discovery: Add support for the STM32L152RCT6 version. - From Gregory Nutt (2018-05-18). - * configs/stm32f4discovery/audio: Add board configuration for CS43L22 audio - example. From Alan Carvalho de Assis (2018-05-19). - * drivers/lcd and configs/olimex-lpc1766stk: Remove support for the - Nokia6100 LCD. That LCD uses a 9-bit SPI interface (the 9th bit being the - command/data bit that is normally a discrete). That communication was - never successfully integrated. I now believe that it would would require - some special support from the low-level, MCU SPI driver to manage that 9th - bit. The deleted code is still available in the Obsoleted repository in - the nuttx/drivers/lcd, nuttx/configs/olimex-lpc1766stk, and Patches - directories. From Gregory Nutt (2018-05-19). - * arch/arm/src/lpc17xx/lpc17_usbdev.c: Fix loss of RX initiatives. USB - bulk endpoints are double buffered on LPC17xx MCUs. This means that up to - two packets might be received on an OUT endpoint that can not be handled - immediately if the receive request queue is empty. Thus, rxpending must - be a counter not a boolean flag. From Michael Jung (2018-05-20). - * configs/imxrt1050-evk/src: Add support for on-board NOR FLASH boot. From - Ivan Ucherdzhiev (2018-05-21). - * fs/fat: In fs_stat(), when stat'ing the root directory, avoid calculating - the address of the root directory entry. The calculation is bogus (but - not harmful) because the root directory does not have a directory entry. - Noted by Boris Astardzhiev. From Gregory Nutt (2018-05-23). - * fs/fat: Avoid calculating the bogus directory entry address for the FAT - root directory (since it has no directory entry). This change should have - no effect, other than making the logic clearer. From Boris Astardzhiev - (2018-05-24). - * configs/indium-f7: Removes support for the Indium-F7 board. This was - done for two reasons: (1) The board support was just clone of the - Nucleo-144 board support with naming changes. There has been no support - and no further development for the board support. (2) There does not seem - to be any available Indium-F7 board available to the public anywhere on - the internet. There is not even a reference to the board on the - rafresearch.com web stie. Gotta go. Its in the way. From Gregory Nutt - (2018-05-24). - * arch/arm/src/imxrt: Add Ethernet driver. From Jake Choy (2018-05-25). - * arch/arm/src/imxrt: Add cache operations to permit the Ethernet driver to - work with the D-Cache enabled, at least in write-through mode. Add - support for PHY interrupts and PHY IOCTLs. - * configs/imxrt1050-evk/netnsh/defconfig: Disable LED support because pins - conflict with PHY. Enable device statistics. Enable NSH ifup and ifdown - commmands. Add an NSH configuration for testing Ethernet.

From Gregory - Nutt (2018-05-26). - * drivers/serial: Add a timeout to uart_tcdrain(). Even if tcflush() is - used to discard buffered data, the close() can still hang if (a) hardware - flow control is enabled, (b) CTS == 1, and (c) there is data stuck in the - hardware Tx FIFO. tcflush() does not currently clear the MCU serial - drivers' hardware Tx FIFOs. This is a workaround for that. From Gregory - Nutt (2018-05-27). - * Build system: Remove fixed lib/ subdirectory and its content. Replace - with new directory called staging/ that is created dynamically when - building and removed when 'make clean' is done. This both improves the - name and eliminates a garbage directory from the repository. From Gregory - Nutt (2018-05-29). - * Build system: Move all build-related files (except the top-level - Makefile) into the tools/ sub-directory. This really cleans up the - top-level directory. From Gregory Nutt (2018-05-29). - * libs/: This commit moves all of the libraries under a common directory - called libs/ (libc, libnx, and libxx). This most certainly break libcxx - for now. From Gregory Nutt (2018-05-29). - * libs/libdsp: Adds DSP support library. From Mateusz Szafoni (2018-05-30). - * arch/arm/src/kinetis: In kinetis_lowputc.c, fix esBRFA calculation - effecting baudrate. Previous BRFA was not cleared and or-ed into new - BRFA, hence, buadrate was wrong. Where Baud Rate Fractional Divisor - (BRFD) UART baud rate = clock / (16 * (SBR + BRFD)) From David Sidrane - (2018-05-30). - * arch/arm/src/kinetis: In kinetis_lowputc.c, fixed parity settings. - Kinetis UART must be placed in 9 bit mode (M=1) with when 8 bit data with - parity is required. If left in 8 bit mode (M=0) with parity then D7 of the - TX/RX register becomes parity bit. Hence what is called 9-bit or 8-bit - Mode Select is a misnomer. 8 bit mode when parity is enabled is realy 7 - bit with parity. From David Sidrane (2018-05-30). - * arch/sim: Various fixes necessary to build the simulator under MSYS2. - From Gregory Nutt (2018-05-31). - * Makefile: The clean_context target needs to invoke a corresponding - clean_context target in the apps/Makefile in order to remove linkages - From Gregory Nutt (2018-05-31). - * configs/stm32f4discovery: Add Load Modules flags to STM32F4Discovery - board From Alan Carvalho de Assis (2018-06-01). - * libs/libc/modlib/modlib_verify.c: Fix backward test for an error.

From Dmitriy Linikov - (2018-06-05). - * arch/arm/src/stm32: STM32 FLASH logic has reached a limit in - complexity and, hence, needs to be divided into multiple C files of - lower complexity. From Gregory Nutt (2018-06-05). - * configs/lc823450-xgevk: Add loopback test for digital MIC on lc823450 - via i2schar driver.

From Juha - Niskanen (2018-06-06). - * stm32f334-disco/buckboost: Use a PID controller from libdsp From - Mateusz Szafoni (2018-06-06). - * arch/: Make sure the up_irq_enable() is available on all - architectures. From Gregory Nutt (2018-06-06). - * Based on a change recommended by Mark Shulte: - Signal handlers maybe run with interrupts enabled or disabled, - depending on how the task the received the signal was blocked. (i.e.: - If sem_wait() is called, then we disable interrupts, then block the - currently running task). This could be dangerous, because user code - would be running with interrupts disabled. - This change forces interrupts to be enabled in up_sigdeliver() before - executing the signal handler calling up_irq_enable() explicitly. - This is safe because, when we return to normal execution, interrupts - will be restored to their previous state when the signal handler - returns. From Gregory Nutt (2018-06-06). - * arch/arm/src/stm32: Ports stm32 ltdc and stm32 dma2d to use the - framebuffer interface From Marco Krahl (2018-06-06). - * syslog: Enable a partial, crippled version of syslog_flush(); - arch/: Call syslog_flush() from assertion handling logic.

Timeouts were in ticks but - should have been in ms. This caused false triggers of timeout - causing redundant packets, etc. From Anthony Merlino (2018-06-13). - * arch/arm/src/lc823450: Add lc823450 Bluetooth support. From - Masayuki Ishikawa (2018-06-13). - * stm32f7: serial: Fix ioctl TIOCSSINGLEWIRE - The TRM notes that UE must be disabled in order to write HDSEL in - USART_CR3. This was not being done, so calls to TIOCSSINGLEWIRE were - silently failing. - This change checks the state of UE in USART_CR1, clears the UE bit - before writing HDSEL, then re-enables it if neccesary. From Kurt - Kiefer (2018-06-14). - * drivers/sensors: Add support for Telair T6713 carbon dioxide - sensor. From Juha Niskanen (2018-06-15). - * arch/arm/src/stm32f7: This change ports in Marco Krahl's STM32F4 - framebuffer overlays for the LTDC and DMA2D into the STM32F7. That - driver was same as the STM32F4 driver. From Gregory Nutt (2018-06-15). - * Eliminate use of the non-standard type systime_t and replace it the - equivalent, standard type clock_t From Gregory Nutt (2018-06-16). - * syscall/: clock_systimer() is no longer a system call. It has been - replaced with the equivalent, standard interface clock() as the - system call. - sched/clock: Move the implementation of clock() from libs/libc/time - to sched/clock. This is necessary because it calls the (now) - internal OS function clock_systimer. clock() is now accessed only - via a system call in certain configurations. From Gregory Nutt - (2018-06-16). - * /arch/arm/src/xmc4: Fix XMC4 SPI.

However, that - static function was still calling HTONS() on the port, incorrectly - converting it back to host byte order. From Gregory Nutt (2018-06-18). - * arch/arm/src/: This commit removes support for the dedicated vector - handling from the many older architectures. Only common vectors are - now supported. From Gregory Nutt (2018-06-19). - * fs/smartfs: Fixed filesystem corruption when writing to small file - after open(... O_APPEND) From Dmitriy Linikov (2018-06-20). - * arch/arm/src/stm32f7: Port input capture from stm32 From Juha - Niskanen (2018-06-21). - * arch/arm/src/armv7a and imx6: Add support for per-CPU IRQ and FIQ - interrupt stacks (bugfix). Add support so that up_assert will print - the correct interrupt stack on an assertion (FIQ stack is still not - printed). From Gregory Nutt (2018-06-21). - * net/udp: When sending a broadcast (or multicast) packet do not - attempt to look up the device by the destination IP address. Rather, - use the locally bound address for these cases to select the correct - network device. From Gregory Nutt (2018-06-22). - * net/: There are many different checks for IPv6 multicast addresses. - Most of the checks are different. RFC 3513 clearly specifies how to - detect an IPv6 multicast address: they should begin with 0xffxx. I - did not change some of the checks in ipv6_input.c, however. In that - file, the comments indicate that the code should only pick of certain - multicast address that begin withi 0xff02. From Gregory Nutt - (2018-06-23). - * net/: Fix a sixlowpan typo bug recently introduced; Rename - g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the - all-zero address is the IPv6 unspecified address (sometime - IN6_ADDR_ANY). Replace more inline tests for IPv6 multicast with - common net_is_addr_mcast() macro. From Gregory Nutt (2018-06-23). - * net/: Rename CONFIG_TCP_REASSEMBLY to CONFIG_IPv4_REASSEMBLY. Add - some fixes to get a clean compile with CONFIG_IPv4_REASSEMBLY - enabled. There are several problems with the current - implementation: It is untested (and depends on - CONFIG_EXPERMIMENTAL). It uses some Ethernet specific definitions - (and depends on CONFIG_NET_ETHERNET). There is only a single - reassembly buffer. The last two issues prevent use of this feature - in any context where IPv4 packets may be reassembled for multiple - network devices concurrently). From Gregory Nutt (2018-06-24). - * net/tcp: Re-think CONFIG_NET_TCP_RWND_CONTROL TCP windowing - controls. From Gregory Nutt (2018-06-24). - * net/udp: Fix a hole in the address lookup logic. From Gregory Nutt - (2018-06-25). - * stm32f7: Fix compile error caused by intentional use of fall through - From Daniel Agar (2018-06-25). - * net/: Add driver interface index support. Add implementation of - if_nametoindex() and if indextoname(). Raw AF_PACKET sockets now - depend on CONFIG_NETDEV_IFINDEX. Add syscall support for - if_nametoindex() and if_indextoname(). - Includes an algorithm to prevent an interface index from being reused - until all network interfaces have by assigned once. The prevents - removable devices from being removed, unregistered and re-installed, - re-registered and keeping the same interface index. From Gregory - Nutt (2018-06-25). - * net/netdev: Fix.. Too many calls to net_unlock() From Gregory Nutt - (2018-06-25). - * net/udp: Add support for the UDP_BINDTODEVICE protocol socket - option From Sebastien Lorquet (2018-06-25). - * configs/stm32f746g-disco: Add support for STM32F746G-disco board - LCD From Marcin Wyrwas (2018-06-25). - * arch/arm/src/stm32f7/chip/stm32f72xx73xx_dma.h: Macros did not - account for the increase from 8 to 16 DMA channels.

From Gregory Nutt (2018-06-26). - * fs/mount/fs_automount.c: Ignore return values from work_cancel(). - From Gregory Nutt (2018-06-27). - * arch/arm/src/lc823450: Fix setintstack macro in chip.h. In case of - CONFIG_SMP=y, g_cpu0_instack_base and g_cpu1_instack_base are not - allocated just after g_instack_alloc but these values show the - addresses for interrupt stack of each CPU. So to set the stack - pointer based on these variables, temporal register has to be used. - From Masayuki Ishikawa (2018-06-27). - * arch/arm/src/imxrt: Add support for the i.MXRT RTC. This initial - commit is code complete (with limited features and options) but untested. - The HPRTC is functional. However, if the LPSRTC is enabled, then - there is a hang during LPSRTC initialization. It appears that there - is some problem in providing clocking and initializing the LPSRTC - domain. From Gregory Nutt (2018-06-27). - * tools/testbuild.sh: Add option to specify location of nuttx - directory. From Gregory Nutt (2018-06-27). - * stm32f7: I2C reset Configure I2C pins as GPIO output. Pins were - reset to inputs in the deinit. This resets them to outputs. From - David Sidrane (2018-06-27). - * Commit 0c963449d6e8f5f8b2dfe96e9de3116633a3749a, 'fs/vfs: Added - support for checking if a descriptor is a socket in fstat().', - changed sys/stat.h in way that breaks smartfs file-type stat flags. - CROMFS is similarly broken, as tools/gencromfs.c was not updated to - match the sys/stat.h changes. This commit fixes both issues. It - probably is not a good idea to use NuttX sys/stat.h bit-field values - directly in stored structure of filesystem. From Jussi Kivilinna - (2018-06-28). - * arch/arm/src/imxrt: Add trivial SNVS from Rev 1. of the Reference - Manual. From Gregory Nutt (2018-06-28). - * arch/arm/src/lpc43: Fix lpc43 CAN configuration. Configuration - settings were used and documented in README.txt files, but never in - any Kconfig file. From Gregory Nutt (2018-06-28). - * tools/refresh.sh: Add a --prompt option that will let you use - --silent but will prompt before overwriting the original defconfig. - From Gregory Nutt (2018-06-28). - * Update tools/link.sh per suggestions by Mark so that it can be used - with MSYS vs copydir.sh.

From - Masayuki Ishikawa (2018-07-03). - * drivers/usbhost/usbhost_max3421e.c: Add support for the Maxim M3421E - USB host driver. From Gregory Nutt (2018-07-03). - * net/udp: Restore some legacy behavior that was lost with the - implementation of CONFIG_NET_UDP_BINDTODEVICE: If no device has a - local address when the broadcast packet is sent and the UDP socket is - not bound to a device, there select some arbitrary device. This is - certainly lunacy in the case where there are multiple network devices - registered because the wrong device will probably be returned. It - works find, however, for the legacy case where only a single network - device is registered. From Gregory Nutt (2018-07-04). - * arch/arm/src/samv7: Add ability for CAN BUS_OFF autorecovery - according ISO11898-1:2015. With this change we added an ioctl for - triggering the autorecovery sequence for BUS_OFF to the CAN-driver - and the SAMV7 low-level driver. According the datasheet: If the - device goes Bus_Off, it will set MCAN_CCCR.INIT of its own accord, - stopping all bus activities. Once MCAN_CCCR.INIT has been cleared by - the processor (application), the device will then wait for 129 - occurrences of Bus Idle (129 * 11 consecutive recessive bits) before - resuming normal operation. At the end of the Bus_Off recovery - sequence, the Error Management Counters will be reset. During the - waiting time after the resetting of MCAN_CCCR.INIT, each time a - sequence of 11 recessive bits has been monitored, a Bit0 Error code - is written to MCAN_PSR.LEC, enabling the processor to readily check - up whether the CAN bus is stuck at dominant or continuously disturbed - and to monitor the Bus_Off recovery sequence. MCAN_ECR.REC is used to - count these sequences. From Frank Benkert (2018-07-04). - * This commit attempts remove some long standard confusion in naming - and some actual problems that result from the naming confusion. The - basic problem is the standard MTU does not include the size of the - Ethernet header. For clarity, I changed the naming of most things - called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now - CONFIG_NET_ETH_PKTSIZE. - This makes the user interface a little hostile. People thing of an - MTU of 1500 bytes, but the corresponding packet is really 1514 bytes - (including the 14 byte Ethernet header). A more friendly solution - would configure the MTU (as before), but then derive the packet - buffer size by adding the MAC header length. Instead, we define the - packet buffer size then derive the MTU. - The MTU is not common currency in networking. On the wire, the only - real issue is the MSS which is derived from MTU by subtracting the IP - header and TCP header sizes (for the case of TCP). Now it is derived - for the PKTSIZE by subtracting the IP header, the TCP header, and the - MAC header sizes. So we should be all good and without the recurring - 14 byte error in MTU's and MSS's. From Gregory Nutt (2018-07-04). - * arch/arm/src/stm32f7/stm32_sdmmc.c: Add SDIO card support. From - Ramtin Amin (2018-07-05). - * net/tcp: Set the default TCP MSS to the value required by RFC 879 - and never change it under any circumstance unless the remote host - requests a larger MSS via an option the TCP header. From Gregory - Nutt (2018-07-05). - * configs/viewtool-stm32f107: Add a TCP performance test using - apps/examples/tcpblaster. From Gregory Nutt (2018-07-05). - * net/tcp: Fix a deadlock condition that can occur when (1) all - network logic runs on a single work queue, (1) TCP write buffering is - enabled, and (2) we run out of IOBs. In this case, the TCP write - buffering logic was blocking on iob_alloc() with the network locked. - Since the network was locked, the device driver polls that would - provide take the write buffer data and release the IOBs could not - execute. This fixes the problem by unlocking the network lock while - waiting for the IOBs.

This configuration requires uses the clk_in, - external crystal clock, to drive the PLL. When that input was - selected, the board bootup failed waiting for the PLL to lock. After - referring the driver from NXP, we should turn on power sources for - the ext clock if system pll input select clk_in. NOTE that the - LPC54628 did not require this step... perhaps because the system - oscillator power was already enabled.

This change avoids - running $(MKSYSCALL) and .context in parallel and ensures that - tools/mksyscall is built before it is actually used. From Masayuki - Ishikawa (2018-07-23). - * arch/arm/src/samv7/sam_mcan.c: Correct an error in the BUS_OFF - reporting. In case of BUS_OFF the old implementation was leading to - a package storm. Now it reports the error condition BUS_OFF only - once. From Frank Benkert (2018-07-23). - * arch/arm/src/kinetis: SDHC fix SDIO driver so that DMA works. - There were 2 problems. The first was that the interrupt did test DINT - and raise a completion events. But since DINT is just an indication - of DMA completion, TC is a valid way to determine that the transfer - is complete. The second problem is that Software Reset For DAT Line - SDHC_SYSCTL[RSTD] clears the bits 24-0 in SDHC_PROTO this looses the - wide bus setting DTW From David Sidrane (2018-07-23). - * arch/arm: Add CONFIG_DEBUG_MEMFAULT to Kconfig. Also, fix - src/armv7-m/up_memfault.c From Masayuki Ishikawa (2018-07-24). - * fs/tmpfs/fs_tmpfs.c: Correct logic in tmpfs_ioctl() that extracts - the priv state structure from the file system structures.

From Ivan Ucherdzhiev (2018-07-26). - * include/sys: Remove unused SYS_nnetsocket from syscall.h. Because - SYS_nnetsocket is not implemented so far, it should be removed so that - SYS_prctl can work correctly. From Masayuki Ishikawa (2018-07-26). - * binfmt/: Refactor binfmt_exec.c. This change also fixes an argv - issue for CONFIG_SCHED_ONEXIT=n or CONFIG_SCHED_HAVE_PARENT=n From - Masayuki Ishikawa (2018-07-26). - * arch/arm/src/imxrt: I finally got the Ethernet CRC32 to work - properly after the FAE pointed me in the right direction: (1) Added - CRC32 functions for multicast address filtering, (2) Do not reset PHY - settings when doing an ifup, (2) Use chip's unique id as the device - MAC, and (4) Enable discard enet frames with errors at PHY layer. - From Jake Choy (2018-07-26). - * arch/arm/src/samd5e5 and configs/metro-m4: Initial commit the port - to the SAMD5x/E5x MCU family and also support for the Adafruit Metro - M4 board. It port is untested and unfinished. It currently will not - even link due to some missing clock related logic. From Gregory Nutt - (2018-07-26). - * configs/stm32vldiscovery: Changed the status LED to be the green one - as mentioned in the README file. Removed the global array for buttons - and replace it with the only button. Improve defconfig for the nsh - configuration. From Ouss4 (2018-07-27). - * arch/arm/src/samd5e5: Completes XOSC32, XOSC0/1, MCLK, and GCLK - configuration logic. Still needs FDPLL and FDLL support. From - Gregory Nutt (2018-07-27). - * arch/arm/src/samd5e5/sam_clockconfig.c: Implement DFLL and DFPLL0/1 - support. This completes coding the the re-architected clock - configuration logic.

As source address the address of the struct - member sigev_value was used, and it is not located the start of the - struct. This leads to invalid data being copied to internal - structure. Both source and destination should be of type struct - sigevent* . From Simon Liedl (2018-07-30). - * arch/arm/src/samd5e5/sam_usb.c: Bring the SAMDL2 USB driver into the - SAMD5E5 port. From Gregory Nutt (2018-07-30). - * drivers/usbhost/usbhost_max3421e.c: Fix several errors found in - early testing. - drivers/usbhost/usbhost_max3421e.c: Mutual exclusion semaphore must - be re-entrant. - drivers/usbhost/usbhost_max3421e.c: Fix unmatched SPI lock/unlock. - From Gregory Nutt (2018-07-30). - * configs/metro-m4: Correct SERCOM3 pin configuration From Gregory - Nutt (2018-08-01). - * stm32f746g-disco: touchscreen support: Fixed FT5x06 driver to - correctly close (previously it unregistered interrupt handler during - close). Also added LittlevGL demo for STM32F746G-DISCO From Marcin - Wyrwas (2018-08-01). - * drivers/analog: Add driver for digital to analog converted DAC7571. - configs/nucleo-l432kc: Add support for a connect DAC7571 converter. - From Daniel Pereira Carvalho (2018-08-02). - * drivers/sensors/adxl345: remove comment references to touchscreens - From Russ Webber (2018-08-02). - * arch/arm/include/armv7-m, arch/arm/include/armv7-m, - arch/arm/include/stm32f7: Add a configuration to enable workaround - for r0p1 Errata 837070: Increasing priority using write to BASEPRI - does not take effect immediately. - This update is required to be serialized to the instruction stream - meaning that after this update completes, it takes effect immediately - and no exceptions of lower priority than the new boosted priority can - pre-empt execution. Because of this erratum, the priority boosting - does not take place immediately, allowing the instruction after the - MSR to be interrupted by an exception of lower priority than the new - boosted priority. This effect is only limited to the next - instruction. Subsequent instructions are guaranteed to see the new - boosted priority. - This was raised in Bitbucket issue 113 from Vadzim Dambrouski. From - Gregory Nutt (2018-08-02). - * net/tcp: Remove g_netstats.tcp.syndrop++ from tcp_data_event() From - Masayuki Ishikawa (2018-08-03). - * include/nuttx/i2c/i2c_master.h: Add a definition to distinguish a - new START of messages from a repeated start. No lower-half I2C - drivers actually implement this new flag bit, however. - drivers/i2c/i2c_writeread.c: Use new repeated START definition where - appropriate. Rename I2C_M_NORESTART to I2C_M_NOSTART since it may be - used in other contexts than a repeated start. Add comments to - clarify setup for repeated start. From Gregory Nutt (2018-08-03). - * configs/nucleo-l432kc: Fix stm32_userleds. After change LD2 to LD3 - in board.h stm32_userleds.c was broken. From Daniel P. Carvalho - (2018-08-03). - * arch/arm/src/stm32f7: This commit ports the stm32f20xxf40xx_flash.c - driver to the STM32F7 platform and fixes some relevant problems in - the header files. From Evgeniy Bobkov (2018-08-03). - * net/netlink: This commit brings in a fragmentary, experimental - implementation of NETLINK sockets. There is not too much to that - socket support on this initial commit, just the netlink socket - framework. However, I decided to bring it into master because there - is a enough that I would not want to lose what is in place. And - since it is dependent on CONFIG_EXPERIMENTAL, its presence on master - should be innocuous. From Gregory Nutt (2018-08-03). - * configs/metro-m4: Add an option to build the Metro M4 image to run - out of SRAM. This ought to be a safer and quicker way to do the - initial bring-up (having bricked the first Metro M4 due to a bad - FLASH image). From Gregory Nutt (2018-08-03). - * Revise the Cortex-M7 workaround: That change had the subtle - side-effect of unconditionally enabling interrupts in the primask. - That may be what we want in most cases, but certainly not all. This - does increase the size of the inline function by about 48-bits per - instantiation. From Gregory Nutt (2018-08-04). - * configs/olimex-stm32-p407: Add kernel ELF (kelf) configuration. - From Gregory Nutt (2018-08-04). - * binfmt/ and sched/group: Re-architect the way that loadable ELF or - NXFLAT modules are unloaded. Memory resources must be recovered when - the task loaded into memory exits. The original implementation used - the death-of-child SIGCHLD signal to perform the unload. There are - several problems with this: It is overly complex, it requires that - the parent task stay resident while the loaded task runs, and it has - fatal logic flaws in the protected and kernel model builds because - the user signal handler attempts to run in the kernel address space. - This commit corrects with using a mindlessly simply BINFMT callback - when the task exits. From Gregory Nutt (2018-08-05). - * Kconfig files: Fix several errors noted by Alex Denisov in Bitbucket - issue 115. From Gregory Nutt (2018-08-05). - * configs/olimex-stm32-p407/kmodule: Add a configuration that can be - used for testing installation of kernel modules in the protected - build. From Gregory Nutt (2018-08-05). - * sched/group: Fix a deadlock when loading an ELF From Masayuki - Ishikawa (2018-08-06). - * arch/arm/src/lc823450: Change C-Buffer under-level control. The - under-level setting was changed from 1KB to 55KB. In previous - implementation, the setting can ben changed by the tx threshold but - it is fixed at startup. Also, check write size and adjust alignment - if needed. - configs/lc823450-xgevk: Change IOB related params for RNDIS. Since - TCP flow control scheme was changed, HTTP audio streaming has not - been working. These IOB params are not optimized but HTTP audio - streaming now works. From Masayuki Ishikawa (2018-08-06). - * arch/arm/src/stm32l4/chip/stm32l4x3xx_pinmap.h: Recent commit removed - some of the pin definitions for STM32L451xx, and probably some other - chips of the STM32L4x3 subfamily, breaking our builds. Some chips of - the subfamily don't have these peripherals, but some do, so that is - not a valid reason to remove them. From Juha Niskanen (2018-08-06). - * stm32f103-minimum: Add blackpill LED support From Russ Webber - (2018-08-07). - * Build System: This change extends support for the two-pass build. - Its primary purpose is to incorporate source logic generated by - applications into the kernel phase of the build. - In the two pass build, the application logic is built during the - first phase, pass 1. In that phase, the application may generate and - install source files in the pass1/directory. The operating system is - built during phase 2 of the build. At that time, those source files - in the pass1/ directory will be built and incorporated into the - kernel address space. - The primary purpose of the pass1/ directory is to such - application-generated kernel symbol tables. For an example of the - use of this feature, look at apps/examples/module/drivers/Makefile. - Kernel symbol tables are needed to support kernel modules. Of - course, addition board-specific logic in, say, configs//src - would have to be included to make use of the application-installed - symbol tables. From Gregory Nutt (2018-08-07). - * configs/olimex-stm32_p407: Add logic to support initialization of - the kernel module symbol table installed in the pass1/ directory - during the application phase of the build. The kmodule configuration - appears to be fully functional. From Gregory Nutt (2018-08-07). - * configs/nucleo-l432kc/include/nucleo-l432kc.h: Fix TIMx clock - configuration. Also removes definitions related to timers not - available in the STM32L432KC. From Daniel Pereira Carvalho - (2018-08-07). - * arch/arm/src/stm32l4: Fix ADC and COMP breakage caused by - CONFIG_STM32L4_STM32L4X2 separation in 9223123c From Juha Niskanen - (2018-08-08). - * configs/nucleo-l452re: Fix TIMx clock configuration. This is cloned - from 391f3715 for nucleo-l432kc. Also fixes DAC build failure. From - Juha Niskanen (2018-08-08). - * arch/arm/src/stm32, stm32f7, stm32l4, and related defconfig files: - The STM32 RTC driver was being selected by the global CONFIG_RTC - option. That is in correct. For example, if you want to disabled - the STM32 RTC and use an external RTC you cannot because the external - RTC also depends on the global CONFIG_RTC. The solution is to add a - new CONFIG_STM32xx_RTC configuration option the permits to you select - or deselect the STM32 RTC but still be able to selecte the external - RTC. From Gregory Nutt (2018-08-08). - * configs/stm32f4discovery/scripts/ld.script: Missing - EXTERN(_vectors) From Gregory Nutt (2018-08-08). - * arch/arm/src/stm32l4: Avoid using redundant - CONFIG_STM32L4_STM32L4X2. This is almost always same as - CONFIG_STM32L4_STM32L4X3. Avoid duplication to reduce macro clutter. - This patch limits CONFIG_STM32L4_STM32L4X2 usage to dependency - tracking and pinmap. Also enable ADC for CONFIG_STM32L4_STM32L4X5 - (untested, but same RM). From Juha Niskanen (2018-08-09). - * arch/arm/src/stm32l4/chip: Merged stm32l4x2xx and stm32l4x3xx pinmap - files. Removed references to stm32l4x2xx_pinmap.h From Daniel P. - Carvalho (2018-08-09). - * arch/arm/src/kinetis: PIT add Liftime and Chaining - arch/arm/src/kinetis: flexcan fix duplicate line and ordering - arch/arm/src/kinetis: kinetis_lowput.c LPUART data format with - parity fix. The 9-bit data mode is typically used with parity to - allow eight bits of data plus the parity - arch/arm/src/kinetis: lowputc LPUART_BAUD_INIT has to be defined. - Build fails with test case enable LPUART0 and make UART1 console. If - HAVE_LPUART_DEVICE is defined then LPUART_BAUD_INIT has to be defined - even if the lpuart is not the console From David Sidrane (2018-08-09). - * - arch/arm/src/kinetis: Add DMA support and use Circular DMA as an - option to augment the RX FIFOs in the Serial driver. From David - Sidrane (2018-08-10). - * fs/proc and sched/environ: Add support for a procfs entry that will - permit examining the environment of any task. From Gregory Nutt - (2018-08-10). - * tools/kconfig2html.c: Update tool to handle tristate types. Fix a - few errors detected in Kconfig files. From Gregory Nutt (2018-08-10). - * arch/arm/src/stm32l4: Add initial support to STM32L4+ chips From - Juha Niskanen (2018-08-13). - * configs/stm32l4r9ai-disco: Add stm32l4r9ai-disco support. From Juha - Niskanen (2018-08-13). - * arch/arm/src/stm32l4: stm32l4xrxx: allow board to override flash - wait states From Juha Niskanen (2018-08-14). - * configs/stm32l4r9ai-disco: Fix HSE clock config and clock board to - maximum 120 MHz From Juha Niskanen (2018-08-14). - * drivers/net/tun.c: Fixed custom tun devname formatting. From Dmitriy - Linikov (2018-08-14). - * net/: Remove all references to CONFIG_NET_USER_DEVFMT. That feature - is now unconditionally enabled. This was done because (1) the - feature does not require very much additional memory, and (2) it - causes confusion in the configuration due to the additional - complexity. Any network drivers that fail to zero the device - structure interface name field (d_ifname) because calling - netdev_register() will, however, get a nasty surprise. From Gregory - Nutt (2018-08-14). - * net/: Change order of logic: Select the user-defined interface name - format BEFORE determining the minor device number. Otherwise, the - default interface name will be used. From Gregory Nutt (2018-08-14). - * tools/Config.mk: Add function CATFILE definition. Currently only - used in apps/builtin/Makefile. From Gregory Nutt (2018-08-15). - * tools/Config.mk: Move the RWILDCARD function definition from - apps/builtin/Makefile to nuttx/tools/Config.mk. It may have a - broader usage than it does now. From Gregory Nutt (2018-08-15). - * arch/arm/src/stm32/stm32_adc.c: Allow multiple channels without DMA - on STM32L15XX From Juha Niskanen (2018-08-16). - * arch/arm/src/stm32, stm32f7, stm32l4: Make STM32F4XX RTC depend on - CONFIG_STM32_RTC.

Actual - implementation is in apps/system/popen() From Gregory Nutt - (2018-08-17). - * include/stdio.h: popen()/pclose() are not available in KERNEL mode - because they depend on task_spawn() which is not available in KERNEL - mode. From Gregory Nutt (2018-08-17). - * fs/procfs/: Add support for /self, a convenient way for getting - information about the currently running task. From Gregory Nutt - (2018-08-18). - * fs/procfs: Add a configuration option to disable environment - variable info. From Gregory Nutt (2018-08-19). - * include/endian.h and libs/libc/endian: Add support for endian.h. - From Gregory Nutt (2018-08-19). - * include/sys/param.h: Add a dummy sys/param.h header file. This is - not a standard file but is used by other systems and having the dummy - file may minimize some porting efforts. From Gregory Nutt - (2018-08-19). - * Remove CONFIG_ARCH_CALIBRATION. It is awkward to use and no longer - necessary now that we have apps/examples/calib_udelay. From Gregory - Nutt (2018-08-19). - * arch/arm/src/stm32f7/stm32_serial.c: Previous logic would invalidate - the data cache as each byte was read from the DMA buffer. This - change adds logic to invalidate the data cache less frequently by - monitoring the state of the Rx DMA buffer cache coherency and - invalidating only regions as necessary. From Evgeniy Bobkov - (2018-08-21). - * net/procfs/netdev_statistics.c: Was not handling the output correct - for the case of an IEEE 802.11 device. From Gregory Nutt (2018-08-21). - * fs/hostfs: Add support for open() append mode From anchao - (2018-08-22). - * fs/hostfs: Add ftruncate support. From Xiang Xiao (2018-08-22). - * sched/symtab: Reference default symtab name to binfmt From anchao - (2018-08-22). - * binfmt/elf: Set priority level to default if parent has no - priority. From anchao (2018-08-22). - * configs: Several applications in apps/ were calling elf_initialize() - nxflat_initialize(), or builtin_initialize() in violation of the - portable POSIX interface. Those calls were removed from the - applications and added to the appropriate board initialization with - this commit. From Gregory Nutt (2018-08-22). - * drivers/wireless/ieee80211/bcmf_netdev.c: Add missing logic to poll - for more Tx data after the last transfer completes. From Gregory - Nutt (2018-08-22). - * configs/: Change CONFIG_BOARD_RESET_ON_CRASH to - CONFIG_BOARD_RESET_ON_ASSERT, arch/: Implement call to board_reset() - if in all implementations of up_assert() when - CONFIG_BOARD_RESET_ON_ASSERT=y.

All binary formats are now - registered centrally vs. in board-specific logic. This simplifies - the usage of the binfmt subsystem. From Xiang Xiao (2018-08-23). - * mm/: add mm_heapmember function and reimplement kmm_heapmember base - on mm_heapmember since this function is very useful if multiple heaps - exist. From Xiang Xiao (2018-08-23). - * pthreads: Add support static pthread stack. Add standard - pthread_attr_setstack() and pthread_attr_getstack(). In all cases - where the stack is released, add check to see which allocator must be - used to free the stack: The user or the kernel allocator. From - xuanlin (2018-08-23). - * arch/arm/src/armv7-m: Implement SYSTICK timer driver From Xiang - Xiao (2018-08-23). - * configs/sim/loadable: Add loadable demo for arch sim - sched/init: Restore previously reverted option to mount block device - for INIT_FILEPATH case - configs/stm3240g-eval/knxwm: Fix build breakage. - configs: With recent changes to apps/ all configurations that build - applications as modules must now also select CONFIG_APPS_LOADABLE. - configs/sim/loadable: Add loadable demo for arch sim - Kconfig and tools/Makefile.unix and : add dynamic application - loadable support From anchao (2018-08-23). - * tools/nxstyle.c: Add capability to detect multiple blank lines. - Single spacing required by the coding standard. Also coding standard - fixes to server .c files for problems found during testing nxstyle. - From Gregory Nutt (2018-08-24). - * Replace non critical PANIC with DEBUGPANIC to save the code space - From Xiang Xiao (2018-08-24). - * Replace all ASSERT with DEBUGASSERT to save the code space From - Xiang Xiao (2018-08-24). - * arm syscalls: svcall/sycall logic needs to get the ucontext argument - from R4 instead of stack since all syscall parameters pass from - registers in syscall.h From Xiang Xiao (2018-08-24). - * arch/arm/armv7-m: MPU: mpu_log2regionceil needs take into account - the offset too From Xiang Xiao (2018-08-24). - * arch/ and task/sched: vfork operation needs to allocate and copy the - task argument too. Also correction of the address correction cannot - depend on the stack pointer since it is not available in all - architectures. Rather calculate the offset from the stack - allocation pointer From Xiang Xiao (2018-08-24). - * include/nuttx/arch.h: Add prototype for an architecture-specific - up_trigger_irq function From dongjianli (2018-08-24). - * include/nuttx/arch.h: Add prototype for an architecture-specific - up_trigger_irq function - arch/, include/nuttx, sched/sched: Add the garbage collection hook - so each architecture can do custom memory cleanup if necessary. - arch/Kconfig: Add configuration CONFIG_ARCH_GNU_NO_WEAKFUNCTIONS to - suppress use of weak functions. Some gnu derived toolchains do not - support weak symbols From Xiang Xiao (2018-08-24). - * include/nuttx/arch.h: Add architecture-specific prototypes for - conversions between physical and virtual address. From ligd (2018-08-24). - * net/arp: arp_find() now checks if the target IP belongs to one of the - local network devices. From Xiang Xiao (2018-08-24). - * net/netdev: add devif_loopback() to check the loopback case where - a packet is being sent to itself. Modify the net driver to call this - function in this case. This function will simply re-inject the - packet back into the network and the network driver will not put - anything on the wire. From Xiang Xiao (2018-08-24). - * include/nuttx/clock.h, sched/sched: Support the CPU load measurement - using timer_lowerhalf_s interface From Xiang Xiao (2018-08-24). - * drivers/timers: Add maxtimeout method to the struct timer_ops_s - interface From Xiang Xiao (2018-08-24). - * drivers/timers: Add a new method to the struct oneshot_operations_s - interface to get the current time from a oneshot timer driver (if it - is available from the lower half) From Xiang Xiao (2018-08-24). - * drivers/net: drivers/net: Add support for Microchip LAN91C111 - driver From Xiang Xiao (2018-08-24). - * arch/sim/src/up_netdriver.c: (1) Remove up_comparemac() check for - matching MAC address. Let's trust that the tap device just return the - packet which belong to us like other real network device hardware. - (2) Add network device statistics support. From Xiang Xiao - (2018-08-24). - * up_internal.h: Define out the prototype for up_netinitialize() if - CONFIG_NETDEV_LATEINIT is also defined From dongjianli (2018-08-24). - * sched/irq/irq_dispatch.c: Ensure vector never points to NULL since - interrupt may happen before irq_initialize() From Xiang Xiao - (2018-08-24). - * sched/irq: Add support interrupt chains in NuttX. IRQ chain is very - useful in these cases: (1) Multiple hardware connect to the same - request line(e.g. PCI), (2) Need multiple driver to support one - hardware block (like Linux MFD) From zhuguangqing (2018-08-24). - * sched/irq/irq_procfs.c: Fix occasional computation error when - fracpart >= 1000 From Xiang Xiao (2018-08-24). - * arch/: Fix an error found in build testing. The prototype of - mpu_log2regionfloor() changed; an additional parameter was added. - However, none of the calls to mpu_log2regionfloor() were updated to - pass the new, additional parameter. From Gregory Nutt (2018-08-24). - * net/arp: Make the function arp_find() thread-safe. It now returns a - copy of the MAC address from the ARP table entry, rather than a - potentially unstable reference to the ARP table entry. From Gregory - Nutt (2018-08-24). - * arch/arm/src/kinetis: I2C ensure timeout on bus error. The code had - a dead wait on I2C_S_BUSY. Noise on the bus would cause the driver to - hang.

From - zhuguangqing (2018-08-27). - * drivers/power: PM: Make power manager service available as soon as - possible: (1) Initialize g_pmglobals at the definition, (2) skip - hold the lock if OS isn't ready From Xiang Xiao (2018-08-27). - * drivers/pm: PM: Add PM_RESTORE to notify driver that device exit - WFI so the driver could restore state. For example, WDT may stop - counting before enter low power state and restore the counting again - in PM_RESTORE notification From zhuguangqing (2018-08-27). - * drivers/power: PM: Add timer to decrease PM level automatically - From ligd (2018-08-27). - * sched/signal: Default Signal Actions. Change some types to - superficially simplify. Add configuration options to enabled - default signal behaviors on a per-signal basis. I don't think users - are prepared for SIGALRM to terminate the task (which is the correct - default behavior if you don't change it). Extend the implementation - of default signals so that it is totally table driven and extensible - by simply mondifying the content of const tables. From Gregory Nutt - (2018-08-27). - * drivers/power/pm_register.c: Fix an error found in build testing. - From Gregory Nutt (2018-08-27). - * drivers/mtd: Add gd25 driver From wangyanjiong (2018-08-28). - * include/limits.h and include/sys/types.h: Fix warning about - 'SIZE_MAX' redefined. include/nuttx/usb/audio.h: Fix warnings due - to '-' used whete '_' intended.

PSR_E_BIT bit should be set for big endian system. - PSR_A_BIT bis is set automatically as arm cortex-r4 reference manual - 3.7.4. So we don't need to set this bit. - arm/armv7-r: Fix some wrong MPU register definition. Change - MPU_RBAR_ADDR_MASK and MPU_RACR_TEX_SHIFT mask as arm cortex-r4 - reference manual. Region Base Address Register 0-4 bits are - reserved. MPU Region Access control register type 3-5 bits. - driver/mtd: fix compilation error. From EunBong Song (2018-08-29). - * drivers/audio/audio_i2s.c: Fix bad NULL pointer check From Juha - Niskanen (2018-08-29). - * sched/group/group_killchildren.c: In some circumstances, - group_killchildren() could have called pthread_cancel() to kill a - task.

Add nxsig_action() to - solve a chicken and egg problem: We needed to use sigaction to set - default actions, but sigaction() would refuse to set actions if the - default actions could not be caught or ignored. - Add configuration option to selectively enabled/disable default - signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT. Fix - some compilation issues. - sched/sched: If a task/thread was already blocked when - SIGSTOP/SIGSTP was received, it will restart in the running state. - It will appear that to the task/thread that the blocked condition was - interrupt by a signal and returns the EINTR error. From Gregory - Nutt (2018-08-30). - * arch/arm/src/lpc43xx: Make WWDT usable again. LPC43xx WWDT driver - was not updated when irq_dispatch grew an argument parameter.

From Gregory Nutt (2018-09-01). - * configs/metro-m4: Verify the CMCC and enable it by default in the - NSH configuration. From Gregory Nutt (2018-09-01). - * configs/metro-m4: Fix problem with SysTick timer running too fast. - This turned out to be a dumb typo in board.h that was providing the - wrong CPU frequency to the SysTick setup logic.

This is an - untested work-in-progress and is intended to be a part of a larger solution - to correctly handling network poll operations. From Gregory Nutt - (2018-09-08). - * sched/signal: Add a generic signal notification facility. Modify the - custom IOB available notifier so that it is now just a wrapper around this - generic signal notification. This generic signal notification facility - will, eventually, be used to support network polling. From Gregory Nutt - (2018-09-09). - * net/tcp and udp: Add logic to signal events when TCP or UDP read-ahead - data is buffered. From Gregory Nutt (2018-09-09). - * net/netdev: Add signal notification for the case where the network goes - down. From Gregory Nutt (2018-09-09). - * sched/signal: In signal notification facility, use sigqueue() to notify - vs. kill(). With sigqueue(), we can pass more info (but still not enough). - From Gregory Nutt (2018-09-09). - * Signals were not a good choice of IPC to implement the poll function for - several reasons: In order to handle the asynchronous poll-related event, a - substantial amount of state information is needed. Signals are only capable - of passing minimal amounts of data. There are also complexities with - performing kernel space signal handlers in kernel space code that is better - to avoid. So, instead of signals, the equivalent logic was converted to run - via a callback that executes on the high-priority work queue. From Gregory - Nutt (2018-09-09). - * net/TCP: Extend the TCP notification logic logic so that it will also - report loss of connection events. From Gregory Nutt (2018-09-09). - * arch/arm/src/lpc43xx: Fix Ethernet TX_EN pin definitions. TX_EN on - LPC43xx can be routed via P0.1 and PC.4 in both MII and RMII mode. Before, - P0.1 was hard-coded for MII and PC.4 was hard-coded for RMII. Also, the - definitions used inconsistent naming (TXEN vs. TX_EN). From Jakob Haufe - (2018-09-10). - * sched/wqueue: Notifier design cleanup. The original concept used - pre-allocated notification data structures. However, the notification data - must persist for an indeterminate amount of time. So the design was - modified to use dynamically allocated data structures. This commit - simplifies the design by removed some residual 'machinery' that is no longer - needed. From Gregory Nutt (2018-09-10). - * sched/sched/sched_waitpid.c: Remove a bad error check. From Gregory Nutt - (2018-09-10). - * mm/iob and sched/semaphore: Work around some issues with the IOB throttle - semaphore. It has some odd behaviors that can cause assertions in - sem_post(). Also, it seems to get outside of its range occasionally. Need - to REVISIT this. From Gregory Nutt (2018-09-10). - * sched/wqueue: Add an option to work queue notifier so that the - notification can occur on different work queues. From Gregory Nutt - (2018-09-11). - * This patch prevent heap corruption as in below case. - - TASK A TASK B - malloc() - mm_takesemaphore() - heap holder is set to TASK B - <--- preempt - ... - task_exit() - Set to current task to - TASK B - Try to release tcb, and - stack memory - free() - mm_takesemaphore() - - Successfully obtain - semaphore because current - task and heap holder is - same. - Free memory.... - Heap corrupt. - - This change forces all de-allocations via sched_kfree() and sched_ufree() - to be delayed. Eliminating the immediate de-allocation prevents the - above problem with the the re-entrant semaphore because the deallocation - always occurs on the worker thread, never on TASK B. - - There could be consequences in the timing of memory availability. We - will see. From EunBong Song (2018-09-11). - * mm/iob: IOB free notifier should accept the work queue ID as a - parameter. The notification may need to run on either the high- or low- - priority work queue. sched/work: Change the default priority of the - low-priority work queue to 100. From Gregory Nutt (2018-09-11). - * net/tcp and net/udp: In the POLLOUT poll logic, request an immediate Tx - poll from the network device bound to the socket. This obviously cannot - work if there is not single device bound to the network device. From - Gregory Nutt (2018-09-11). - * kinetis: i2c On failed reset re-init i2c and clocking. If a reset fails, - we still must reinitializes the i2c block so that subsequent transfers will - not cause a hard-fault due to the clock being off. If that transfer fails - it can try to reset again. From David Sidrane (2018-09-11). - * net/tcp/tcp_netpoll.c: Add logic to receive notifications when IOBs are - freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER). At - present, does nothing because the logic in in psock_tcp_cansend() does not - check for the availability of IOBs. That will change. From Gregory Nutt - (2018-09-11). - * mm/iob: iob_navail() was returning the number of free IOB chain queue - entries, not the number of free IOBs. Completely misnamed. From Gregory - Nutt (2018-09-12). - * net/tcp/tcp_netpoll.c: Add logic to receive notifications when IOBs are - freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER). At - present, does nothing because the logic in in psock_tcp_cansend() does not - check for the availability of IOBs. That will change. - - mm/iob: iob_navail() was returning the number of free IOB chain queue - entries, not the number of free IOBs. Completely misnamed. - - net/tcp/tcp_send_buffered.c: Extend psock_tcp_cansend() so that it also - requires that at least on IOB is also available. - - net/tcp/tcp_netpoll.c: tcp_iob_work() needs to free the allocated - argument when it is finished. - - sched/wqueue/kwork_notifier.c: Redesign some data structures. struct - works_s must appear at the beginning of the notifier entry structure. - That is because it contains the work queue indexes. This solves a - hard-fault issue. From Gregory Nutt (2018-09-12). - * net/udp/udp_netpoll.c: Port TCP poll changes to UDP. From Gregory Nutt - (2018-09-12). - * tools/Config.mk: Fix an error in RWILDCARD implementation From Anthony - Merlino (2018-09-12). - * mm/iob: Add a divider that can be used to reduce the rate of IOB - notifications. From Gregory Nutt (2018-09-13). - * tools/Directories.mk: Correct the path to the installed libcxx - directory. From Gregory Nutt (2018-09-13). - * fs/smartfs/smartfs_smart.c: Current sector should have a space for next - entry size. If not, we should move to next sector. From EunBong Song - (2018-09-14). - * task/task_restart.c: Restarted with sigprocmask set. Should have been - cleared. Noted by Jeongchan Kim From Gregory Nutt (2018-09-14). - * net/usrsock: Revert commit 'net/usrsock: Optimize option dependence'. - Re-allow combination of usrsock and NuttX TCP/IP stack. For example, in - case device has Ethernet and mobile connectivity and NuttX TCP/IP stack is - used when configured to use Ethernet connection and usrsock when - configured to use modem (modem TCP/IP stack through usrsock). From Jussi - Kivilinna (2018-09-14). - * libs/libc/wqueue/work_usrthread.c: Eliminate a race condition noted by - Xiang Xiao. Use sigprocmask() so that we do not lose a signal. From - Gregory Nutt (2018-09-14). - * fs/vfs/fs_open.c: Add nx_open() which is the same as open() except that - it does not create a cancellation point nor does it modify the errno - variable. - - many locations: Change occurrences of open() followed by file_detach() to - file_open(). Change most non-controversial calls to open() to nx_open(). - - fs/inode/fs_fileopen.c: Add file_open() implementation with some interim, - placeholder logic. From Gregory Nutt (2018-09-15). - * include/nuttx/fs/fs.h: Fix some backward parameters in a new macro - definition. From Gregory Nutt (2018-09-15). - * Replace calls to ioctl() in the OS to file_ioctl() From Gregory Nutt - (2018-09-15). - * configs/stm32l4r9ai-disco/src/stm32_adc.c: Replace calls to ioctl() in - the OS to file_ioctl() From Gregory Nutt (2018-09-15). - * Rename file_close_detached() to just file_close() for better consistency - in naming. From Gregory Nutt (2018-09-15). - * fs/inode/fs_fileclose.c: Move file_close() a separate file. It no - longer makes sense for it to cohabitate with file_detach(). From Gregory - Nutt (2018-09-15). - * configs/b-l475e-iot01a/include/b-l475e-iot01a_clock.h: Correct timer - source clock frequencies. From Freemans Goden (2018-09-16). - * tools/tesbuild.sh: No longer installs and builds the NxWidgets - libraries. They are now a port of apps/. From Gregory Nutt (2018-09-16). - * I2C support for STM32H7 - - - stm32h7/chip.h: Update peripherals - - stm32h7x3xx_rcc.h: Update definitions - - stm32h7x3xx_rcc.c: Remove some unused code and configure I2C clocks - - stm32h7: add lower half I2C driver (based on F7 I2C driver) - - configs/nucleo-h743zi: Add LSM303AGR and LSM6DSL configuration - - sensors/lsm303agr.c, sensors/lsm6dsl.c: add missing include, remove - whitespace From raiden00pl (2018-09-16). - * libs/libc/math: Add variable convergence in log() and logf() to avoid - hangs caused by failure to converge for very specific input values. - - libs/libc/math: Small change to log() and logf() that improves accuracy - and convergence time From Rajan Gill (2018-09-16). - * drivers/timers: RTC_PERIODIC is no longer EXPERIMENTAL, remove - unimplemented EXPERIMENTAL RTC configuration variables. From Juha - Niskanen (2018-09-17). - * C library: Add some new functions defined in POSIX.1-2017: stpncpy(), - strsignal(), psignal(), psiginfo(). From Gregory Nutt (2018-09-17). - * libs/libc/string/lib_stpncpy.c: Correct the return pointer value for the - case where the NUL terminator is transferred. From Gregory Nutt - (2018-09-18). - * drivers/usbdev: Fix buffer overrun check in rndis.c. The RNDIS driver has - been working since 13 Nov 2017. However, I finally found that it depends - on network and buffer configurations. If a receiving TCP packet is - divided into smaller ones based on USB max packet size, this condition - check works correctly. From Masayuki Ishikawa (2018-09-20). - * - mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks - - page is a unit for read/write operation. - eraseblock is a unit for erase operation. - up_progmem_npages is a little bit confusing because it returns number of - erase blocks in flash memory. This patch changes up_progmem_npages to - up_progmem_neraseblocks. There is no logical change. - - - mtd/progmem: up_progmem_erasesize. - - Change argument name to be more readable. - - - mtd/progmem: up_progmem_eraseblock - - Change up_progmem_erasepage to up_progmem_eraseblock. - eraseblock is more readable name than erasepage. - - - mtd/progmem: change up_progmem_eraseblock's return value. - - up_progmem_eraseblock erase a block. so it's better to return the erase block - size than page size. - - - arm/cortex-r : fix wrong cp15_flash_dcache. - - change mcrne to mcr for unconditional dcache. From EunBong Song (2018-09-21). - * arch/arm/src/armv7-a: Replicate the same fix was previously committed for - the armv7-r. From Gregory Nutt (2018-09-20). - * arch/arm/src/lc823450: Fix up_allocate_heap() in - lc823450_allocateheap2.c. For lc823450, heap area in flat build mode must - start just after _eronly. Because bss/data area is allocated in lower - address than text area in SRAM. See ld.scripts for details. Also, this - change removes unused up_allocateheap.c From Masayuki Ishikawa - (2018-09-21). - * arch/arm/src/stm32f7: Remove adhoc PM interfaces and add CONFIG_PM serial - suspend. From Gregory Nutt (2018-09-21). - * arch/arm/src/kinetis: Remove all attempts to reprioritize interrupts. - From Gregory Nutt (2018-09-21). - * arch/arm/src: Correct all ARMv7-M architectures. Interrupts were not be - disabled correctly on power up. Writing zero to the NVIC SET-ENABLE - registers has no effect. In order to disable interrupts, it is necessary - to write all ones to the NVIC CLEAR-ENABLE register. Noted by David - Sidrane. From Gregory Nutt (2018-09-21). - * net/tcp/tcp_recvwindow.c: In order to receive data we must not only have - IOBs available, but we must also have at least one IOB chain qentry - available. Otherwise, we will advertise that we an buffer a lot of data - when, in fact, we cannot. This is an experimental fix to a performance - problem noted by Masayuki Ishikawa. From Gregory Nutt (2018-09-22). - * fs/driver: Add support for named MTD drivers in the pseudo file system. - This will, eventually, allow us to mount file systems that need MTD - drivers without having to fake an intervening block driver. - fs/driver and fs/mount: Add mount() support for file systems that require - MTD drivers (vs. block drivers). From Gregory Nutt (2018-09-22). - * include/sys/socket.h: Renumber the socket types. They must begin at 1, - not zero. Socket type zero has a special meaning for some interfaces. For - example, getaddrinfo() uses a socket type of zero to many any type of - socket. The is no standard name for the any-type-socket, but macOS uses - SOCK_UNSPEC. NuttX will do the same. Issue noted by Anthony Merlino. - From Gregory Nutt (2018-09-24). - * Brings in an initial port of version 0.3.7 of Peter Anderson's SPIFFS - flash file system into NuttX. From Gregory Nutt (2018-09-24). - * arch/arm/src/imxrt/imxrt_enet.c: The board would not come up if I ran - Nuttx from cold. I dumped the PHY registers to see what the differences - were and the PHY was coming up in NANDTree mode. This is a mode for - testing connectivity between the PHY and the MAC. Switching this mode off - in the PHY registers has fixed the problem. From Dave Marples (2018-09-25). - * net/tcp/tcp_wrbuffer.c: Fix buffer release handling on failed buffer - alloc. Attempt to release write buffer on failed TCP write I/O buffer - alloc and tryalloc failed to wrb->wb_iob assertion. From Harri Luhtala - (2018-09-25). - * drivers/net/enc28j60.c: Adjust debug trace levels. Correct typos in some - comments. From Harri Luhtala (2018-09-25). - * A few improvements to getaddrinfo: (1) Use the protocol and socktype - hints in returned address, (2) Ignore AI_PASSIVE argument if hostname is - not NULL From Anthony Merlino (2018-09-25). - * Fixes issue with libcxx build. This was changed multiple times, but - should be fixed now. From Anthony Merlino (2018-09-25). - * include/nuttx: Fix definitions used to access OS functions within the - libraries. In the FLAT build, we must always set the errno and/or create - cancellation points because the same library functions are used within the - OS as are used by applications. This could cause issues for the OS but - corrects some problems at the user interface. Noted by Federico - Braghiroli in Bitbucket issue 121. From Gregory Nutt (2018-09-26). - * arch/arm/src/imxrt: Add LPI2C driver. From Ivan Ucherdzhiev (2018-09-26). - * arch/arm/src/imxrt/imxrt_lpsrtc.c: SVNC LPCR register bits 0 & 1 are NOT - reserved and are, in fact, needed to enabled the SRTC. Now the SRTC is - working. From Ivan Ucherdzhiev (2018-09-26). - * arch/arm/src/imxrt/imxrt_enet.c: Fix a race condition in setting up the - Ethernet Tx transfer. From Dave Marples (2018-09-26). - * arch/arm/src/lc823450: MPU support for FLAT build From Masayuki Ishikawa - (2018-09-27). - * Corrections for the i.MXRT Ethernet: - - (1) Now the Ethernet is completely re-initialized when an error occurs by - means of taking the interface down and back up but the PHY is _not_ - renegotiated for that case because that is very time consuming and an - error in the Ethernet is no reflection on the state of the PHY anyway. - (2) Explicitly sets the expected PHY address to zero (this could be moved - into the config) rather than searching for it which takes ages, and - it's zero anyway for this board (that's the broadcast address, and - anything that cannot respond on that has multiple PHYs, so that would - be a new board). - (3) Allows for the renegotiation of the PHY to be optional when a reset is - needed. If a non-renegotiated reset doesn't result in good comms to - the PHY then it'll automatically be escalated to a renegotiated one. - (4) Only performs a reset for errors that need it (the CRITICAL_ERROR - define). The list of errors that need reset are somewhat arbitrarily - chosen based on my prejudices and might need to be revisited, but - certainly the jabber errors don't need reset, the partial packet is - thrown away by the layer above anyway. - (5) Re-loads the multicast table on reset. - (6) Adds a bit more logging into the imxrt Ethernet module. From Dave - Marples (2018-09-28). - * fs/spiffs: SPIFFS is basically functional although still immature. From - Gregory Nutt (2018-09-28). - * drivers/leds/max7219.c: Support all digits presented in the MAX7219 - datasheet.

From Gregory Nutt (2018-09-30). - * Documentation/NuttShell.html: Update document to describe the 'export' - command, the CONFIG_NSH_VARS setting, and the effect of this setting on - the behavior of the 'set' and 'unset' commands. Add description of the - PATH environment variable. From Gregory Nutt (2018-10-01). - * EFM32, STM32 (FS/HS), STM32F7, and STM32L4 OTGFS/HS: Th epin_configure() - function used the same eptype as the TxFIFO number for all endpoints. - This should probably be the physical EP number, not the EP type. - Suggested by Key Two. From Gregory Nutt (2018-10-02). - * libs/libc/stdio/lib_sscanf.c: Fix conversion for format specifiers that - appear right after a floating point format specifier. When performing a - floating point conversion the parsing code could consume more than - required characters from the input buffer. This made impossible to convert - input of form "1.1K" using format "%f%c". Fix the issue by advancing the - input buffer with the actual characters converted as a float point - number. From Mihai Serban (2018-10-03). - * stm32h7/rcc: update rcc defs, add SPI clock configuration and some fixes - in rcc - stm32h7: initial defs for SPI - stm32h7: initial defs for MDMA, DMA, BDMA and DMAMUX - From raiden00pl (2018-10-04). - * stm32_tim.c: don't use hard-coded UIF interrupt in some functions From - raiden00pl (2018-10-04). - * configs: add support for nucleo-f302r8 board From raiden00pl (2018-10-05). - * libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option does, - indeed, make the printf family of functions much smaller. But it also - adds a lot of complexity and makes the functions non-standard. Removing - this might break some of the tinier platforms but it is the best thing to - do for long term maintenance for for OpenGroup.org compliance. - - libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width - problem if Issue 35 for the cases of integer, long and long long integer - types. The output now matches the output form glibc. From Gregory Nutt - (2018-10-05). - * configs/olimex-stm32-p407: Added a HID keyboard configuration. From - Gregory Nutt (2018-10-06). - * configs/olimex-lpc1766stk: Add support to initialize a USB HID keyboard. - Still don't have a working configuration. Seems to require a lot of - transfer descriptors. Also reorganized some logic. It has been a long - time since the Olimex LPC1766-STK has had any TLC. - - configs/olimex-lpc1766stk/hidkbd: Add a configuration for testing the HID - keyboard. From Gregory Nutt (2018-10-06). - * drivers/wireless/ieee802.11: Add capability for Broadcom chips to get - firmware and CLM data from a mounted file system vs. in-memory data - structures.

From Gregory Nutt (2018-10-10). - * arch/mips/include/mips32/cp0.h: Fix some copy-paste errors that cause - malformed comments and syntax errors when certain CP0 CONFIG1 bits are - referenced. Note in Issue 123 by Anonymous. From Gregory Nutt - (2018-10-12). - * arch/arm/src/lpc43xx/lpc43_serial.c: Fix copy-paste error: - g_usart1port->g_uart1port. From Dave Marples (2018-10-12). - * arch/arm/src/imxrt/imxrt_lpi2c.c: Fixes 2 bugs in the for IMXRT1050: (1) - I2C time out and did not send STOP condition when sending single byte, (2) - I2C could not receive bytes after repeated start.

I do not find any references to PCB Logic on the web and I do not - believe that this breakout board is available any longer. From Gregory - Nutt (2018-10-17). - * drivers/mtd: Add support to Macronix MX25LF25635F serial NOR flash From - David Sidrane (2018-10-17). - * drivers/mtd/s25fl1.c: During a MTDIOC_GEOMETRY ioctl call, the driver was - incorrectly reporting the blocksize to be the same as the erasesize. The - blocksize should be 256 (the page size). This patch fixes that, and now - the SmartFS configration is working. From Ken Pettit (2018-10-18). - * configs/bambino-200e/include/board.h: Correct calculation of SDMMC clock - configuration. The LPC43 has no SDMMC source clock divider. Error noted - by Dave Marples.

From Daniel P. - Carvalho (2018-10-19). - * configs/lpcxpresso-lpc54628/include/board.h: Update logic used to - calculate SDMMC input clock divider. From Gregory Nutt (2018-10-21). - * Fix the LPC4330 family SDMMC card access. Some of these fixes (e.g. DELAY - register) may also be applicable elsewhere. These are _NOT_ extensively - tested, but they are certainly better than the current state of the - driver. The fixes, specifically, are; - - - Clocks were wrongly configured - way too fast because there is no - primary divider on LPC4330 - - This is fixed by means of changing the definitions in the board.h file. - I've edited the one for the lpc4330-xplorer board because I'm actually - working with Versiboard and don't want to contribute that config just - yet while I've still got the drains up on it. - - - The LPC43_SDMMC_DELAY register was not being set - - I suspect, in the 'real world', it's possible to get away without - setting this, but I've added a register definition, default value and - register access macros into arch/arm/src/lpc43xx/chip/lpc43_scu.h and - then used them in arch/arm/src/lpc43xx/lpc43_sdmmc.c. - - - The LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong - values. - - The management have already implemented a rather nice block level - interface for the stm32 so I've just re-used that to write to these - registers as required. I'm slightly nervous that accessing the - configuration registers (SCR being the prime example) which has a much - smaller block size may not be being done in the right way but it does - seem to work correctly, so let's assume it's all OK until someone tells - me otherwise. - - These fixes have been tested with DMA-based read/write on a LPC4330. Speed - via nsh is pretty low but I'm assuming that's just a - buffering/implementation issue for now. From Dave Marples (2018-10-21). - * arch/arm/src/lpc54/lpc54_sdmmc: Port Dave Marple's LPC43 USB DCD fix to - the LPC54 with appropriate naming changes. From Gregory Nutt (2018-10-21). - * arch/arm/src/stm32f7/stm32_flash.c: Allow programming OTP blocks through - progmem interface From Jussi Kivilinna (2018-10-22). - * arch/arm/src/lpc54xx/lpc54_sdmmc.c: Tested Dave Marple's LPC43 fix with - the LPC54. The driver still does not work on the LPC54. This commit adds - support for and SDMMC errata and setting of the delay register which was - missing in the previous commit. It appears that now I can read the SD - card successfully, but I get CRC errors when writing to the card. From - Gregory Nutt (2018-10-22). - * arch/arm/src/lpc43xx/lpc43_sdmmc.c: This commit corrects a problem in - lpc43_dmasendsetup(). There was no linked DMA descriptor code on the send - side. The end result was stalls while sending multiple sectors. This - commit adds that in and the send code is working much better. From Dave - Marples (2018-10-23). - * arch/arm/src/lpc54xx/lpc54_sdmmc.c: This commit ports Dave Marple's DMA - fix for the LPC43 SD/MMC to the LPC54.

From Sakari Kapanen (2018-10-24). - * libs/libc: Correct some errors in psignal() and stpncpy(). From Lokesh B - V (2018-10-24). - * configs/nucleo-l432kc/include/board.h: Fix SPI pin definitions. From - Daniel P. Carvalho (2018-10-24). - * With these changes the SDMMC card for LPC4330 is now working properly BUT - it needs more testing, especially with different cards etc. This code - should be applicable to all members of the lpc43xx family. - - In addition to the problems that were previously identified there were a - few other bits and pieces outstanding; - - - Timing was dependent on CPU speed rather than absolute time - - End of transfer handling was a bit mixed up - - It's possible for data to still be in the FIFO (i.e. not have reached - the card) when a next write is requested, so we need to wait for that to - complete - - Interrupt Status could be carried over from one transfer episode to the - next, corrupting progress - - Multi-descriptor DMA writing simply wasn't implemented, but there were no - indications ... it just failed silently From Dave Marples (2018-10-24). - * arch/arm/src/lpc54xx/lpc54_sdmmc.c: Ported the last of Dave Marples fixes - to the LPC54. Not yet verified. From Gregory Nutt (2018-10-24). - * drivers/wireless/ieee80211/bcmf_core.c: There were two functions that - have a address issue.

However, there was a non-standard version of - that structure in sys/sockio.h. This commit removes the non-standard - version of struct ip_msfilter and adapts the IOCTL and device lookup logic - in net/netdev to work with the new, semi-standard version in - netinet/in.h. From Gregory Nutt (2018-10-29). - * This commit brings in support for the GAP8 architecture. The GAP8 is a - 1+8-core DSP-like RISC-V MCU.

From Gregory Nutt (2018-10-31). - * net/mld: Add basic build structure for Multicast Listener Discovery - (MLD). No yet functional. From Gregory Nutt (2018-10-31). - * Add new configuration CONFIG_NET_MCASTGROUP. This option is selected - automatically if either CONFIG_NET_IGMP or CONFIG_NET_MLD are selected. - Most conditional logic based on CONFIG_NET_IGMP replaced with conditioning - on CONFIG_NET_MCASTGROUP. From Gregory Nutt (2018-10-31). - * net/inet: Add framework to support IPv4 and IPv6 protocol socket options - (i.e., SOL_IP and SOL_IP6). Handling of these socket options is a - necessary step on the way to future ICMPv6 MLD support. From Gregory Nutt - (2018-10-31). - * net/inet/ipv4_setsockopt.c: Add implementation for all IPv4 socket - options that have implemented IOCTL command counterparts. From Gregory - Nutt (2018-10-31). - * configs/imxrt1050-evk/src: Previous committed implemented atypical - SPI-based MMC/SD card support conditioned on CONFIG_MMCSD. This is, of - course, incorrect and interferes with the implementation of correct MMC/SD - card support using the correct SDIO-based peripheral. This commit renames - that atypical support to *mmcsd_spi* and conditions using that atypical - support on CONFIG_MMCSD_SPI with should then not interfere with the - correct MMC/SD support that can be conditioned on CONFIG_MMCSD_SDIO. From - Gregory Nutt (2018-10-31). - * arch/arm/src/imxrt/imxrt_usdhc.c: Initial commit of the i.MXRT SDHC - driver. This driver is partially functional, working in PIO mode. DMA - support and additional testing are needed. From Dave Marples (2018-10-31). - * This change is needed specifically for the case where a boot loader sets - the SPE bit before starting NuttX. In that case, the test in the SPI - driver is bogus. This change fixes that by assuring that NuttX has booted - and initialized at least once (whether or not SPE is set) before the - driver starts refusing to initialize. - - arch/arm/stm32*: Don't rely on SPI_CR1_SPE to determine if peripheral has - been initialized yet. From Anthony Merlino (2018-11-01). - * Xbee getset txpwr - - - drivers/wireless/ieee802154/xbee: Minor improvements to debug facilities. - - drivers/wireless/ieee802154/xbee: Add support for setting/getting tx - power. - - From Anthony Merlino (2018-11-01). - * net/mld: Initialize implementation of MLD.

From Gregory Nutt (2018-11-01). - * drivers/sensors/mlx90614.c: Fix MLX90614 to re-flash new device address - From Alan Carvalho de Assis (2018-11-02). - * net/inet/ipv6_setsockopt.c: Implement the IPV6_JOIN_GROUP and - IPV6_LEAVE_GROUP socket options. - - net/devif/ipv6_input.c and net/icmpv6/icmpv6_input.c: Add logic to skip - over the variable number of IPv6 extension headers that may be present - between the IPv6 header and the transport layer header. The extension - headers are simply ignored. This is necessary because with MLD, certain - incoming messages may have, at a minimum, a Router Alert Hop-by-hop - extension header. - - net/devif, net/tcp, and net/udp: Extend so that all support Transport - protocols supported by IPv6 can handle the presence of IPv6 header - extension options. From Gregory Nutt (2018-11-02). - * net/mld: Updates from comparison with roughly leveraged code and the MDL - RFCs 2710 and 3810. - - net/mld: Defer all timeout-related operations to the work queue vs. - handling within the timer interrupt. Need to notify the device driver for - an immediate poll when there are MLD packets waiting to be sent. From - Gregory Nutt (2018-11-03). - * net/igmp: Backport some MLD design improvements/fixes. From Gregory Nutt - (2018-11-04). - * net/mld: Implement MLDv1 compatibility mode. This completes coding of - MLD. MLD is, however, still completely untested. From Gregory Nutt - (2018-11-04). - * net/mld: Fix some compile errors fill debug info is enabled. Fix some - errors in formatting the Listener report. Still has a checksum error. - From Gregory Nutt (2018-11-04). - * tools/configure.c: Add missing '\n' in printf statement - - tools/configure.c: Add missed -g option to getopt() string - - tools/configure.c and tools/configure.sh: Fix Windows native pre-build - kconfig-conf incompatibility. Looks like pre-built Windows native - kconfig-conf interprets "..\apps" as "..apps" (possibly '\a' as - escape-sequence) so expand winnative path to double-backslashed variant - "..\\apps". - - tools/mkdeps.c: Fix '\0' missing in MinGW. Implicit bug. There are 2 - cases. - - 1. Under Linux. The code works as planned: '\n' is always replaced with - '\0' due to sprintf fills n-1 bytes and reaches buffer length limit. - - 2. Under Windows/MinGW. There is memory corruption. Seems like it`s a bug - inside MinGW/snprintf. Snprintf fills consecutively "oldbase",' - ',"str",'\n', but does not inserts trailing '\0' instead of '\n'. And - when next append() occurs, strlen() returns garbage-appended "oldbase". - - So the fix just removes '\n' and reserves space for '\0'. - - tools/link.bat: Fix .fakelink creation - - configs/Makefile and tools/Config.mk: Move single file copy to the new - function COPYFILE. This fixes the Windows native build case when there is - no cp or cp does not recognize Windows paths. From Anatol Ivanov - (2018-11-05). - * configs/nucleo-l432kc: Add support for the INA226. From Daniel P. - Carvalho (2018-11-05). - * tools/Config.mk and tools/Makefile.win: Force use 'cmd' for shell with - windows native build From Anatol Ivanov (2018-11-06). - * tools/Makefile.win/unix: Staging directory (and its libraries) should be - removed on 'make clean' (issue noted by Dave Marples). From Gregory Nutt - (2018-11-06). - * net/procfs: Add support to provide MLD stats at /proc/net/mld. net/mld: - Fix a couple more bugs found in further MLD testing. From Gregory Nutt - (2018-11-06). - * Adding imxrt 106x - - - imxrt: Fix comment in imxrt105x_memorymap - - imxrt: Add imxrt1060 memory map - - imxrt: Add imcrt106x to imxrt_memorymap - - imxrt: Add i.MX RT 106x to Kconfig - - imxrt: Moved IMXRT_GPIO_NPORTS to chip.h & fixed comments - - imxrt: 105x IRQ fix comment - - imxrt: gpioirq GPIO4,5 using wrong boundary - - imxrt: Add RT106x irq headers & Kconfig - - imxrt: Add rt106x GPIO chip headers - - imxrt: Extend Number of GPIO ports - - imxrt: Add 106x DMAMUX header - - imxrt: iomuxc add 106x - - imxrt: 106x iomuxc extend Indexes - - imxrt: pinmux Add 106x - - imxrt: clockconfig use imxrt_memorymap.h - - imxrt: allocateheap use OCRAM2 as BASE when available - - From David Sidrane (2018-11-06). - * net/mld: Implement 'Other Querier Present Timer'. This timer is used to - revert to Querier mode if there is no other querier on the network. Also, - fix some naming: The Done message is not just Version 1 but is used with - Version 2 as well. From Gregory Nutt (2018-11-07). - * Reported by Anonymous in Bitbucket Issue #129: When MIPS port is built - for microMIPS and then loaded as an application, the __start entry point - is entered in microMIPS mode, but the CPU core initialization code there - misses to set the config3ISAOnExc bit to 1. Subsequently, exceptions are - entered in MIPS32 mode, but the code base was built for microMIPS. From - Gregory Nutt (2018-11-07). - * sched/group/group_foreachchild.c: group_foreachchild iterate by reverse - order since the callback(e.g. group_killchildren) may remove the tcb from - list - - sched Kconfig and sched/task/exit.c: Add SCHED_EXIT_KILL_CHILDREN option - to kill all child threads when the main thread of a task exits. From - zhangyuan7 (2018-11-08). - * binfmt/ and libs/libc: Make exepath_*() more common: - - 1. Move exepath_*() related code to libc/misc - 2. Rename exepath_ to envpath_ - 3.

From Petteri Aimonen (2018-10-31). - * NuttX: USB Composite and DFU drivers: Add support for Microsoft OS - descriptors. - - These Microsoft-only descriptors help in loading the correct driver on - Windows. They are especially helpful to give libusb access to a custom - device without having to manually configure/install WinUSB driver. - - With this change DFU interface works automatically on Windows 10 with - dfu-util 0.9 and libusb 1.0.22. On Windows 7 it still appears to need - driver installation. From Petteri Aimonen (2018-11-02). - * NuttX: STM32F407VG has only one DAC. NDAC=2 causes compilation error when - trying to use e.g. STM32_DAC1_CR macro. From Petteri Aimonen (2018-11-09). - * RNDIS composite support - - - NuttX usb/composite.h: Forward-declare composite_devdesc_s. - - This avoids "error: conflicting types for 'composite_initialize'" - on some versions of GCC. Because of the cross-inclusion between - usbdev.h and composite.h, the full declaration is not always - available. - - - NuttX: USB Composite driver: Fix strid comparison - - The last string ID used by composite driver is 4, and - the number of IDs used is 5 (0..4). The comparison - strid <= COMPOSITE_NSTRIDS caused composite driver to - reply with -EINVAL for id 5, even though it should be - available for sub-devices to use. - - - NuttX: RNDIS USB driver: Add support for composite configuration. - From Petteri Aimonen (2018-11-09). - * FAT improvements - - - NuttX: Add CONFIG_FAT_LFN_ALIAS_HASH to speed up creating long filenames. - - Long filenames on FAT file systems have associated 8.3 character alias - short filenames. The traditional form of these is FILENA~1.EXT with - a running count of the number of similar names. However creating this - unique count can take several seconds if there are many similarly named - files in the directory. Enabling FAT_LFN_ALIAS_HASH uses an alternative - format of FI0123~1.TXT where the four digits are a hash of the original - filename. This method is similar to what is used by Windows 2000 and - later. - - - NuttX: Add CONFIG_FAT_LFN_ALIAS_TRAILCHARS alternative format for 8.3 - filenames. - - Traditional format for long filename 8.3 aliases takes first 6 - characters of long filename. If this option is set to N > 0, - NuttX will instead take first 6-N and last N characters to form - the short name. This is useful for filenames like "datafile12.txt" - where the first characters would always remain the same. - - - NuttX: FAT32: Fix file date corruption in fat_truncate(). - - - NuttX: if SD card wait seems to be a long one, give time for other - threads to run.

From Xiang Xiao (2018-11-09). - * net/arp and icmpv6: Double the delay time on each iteration for ARP/ICMP - to fight work jitter better. From Xiang Xiao (2018-11-09). - * net/icmpv6, neighbor, and netdev: Rename netdev_dev_lladdrsize() to - netdev_lladdrsize() and move the prototype to include/nuttx/nex/netdev.h, - giving is global scope within the OS. Reviewer: This degrades the - integrity of the modular architecture by introducing a new coupling via C - function call. Not a good thing at all.

Recommended by Xiang Xiao in order to avoid the long - delays of bringing some networks back up. - - Normally it is required that the network be in the "down" state when - re-configuring the network interface. This is thought not to be a - necessary here because. - - 1. The ICMPv6 logic here runs with the network locked so there can be no - outgoing packets with bad source IP addresses from any asynchronous - network activity using the device being reconfigured. - 2.

From Gregory Nutt (2018-11-11). - * The MLD implementation did not follow the RFC correctly when it is the - Querier. The Querier should use a general query and get query messages - from all members of all groups. This would be driven by a single timer - per sub-net since all groups are queried at once. Instead, the design - used a Multicast Address Specific Query with one timer per group and - ignores groups that we are not members of. - - Similarly, the MLDv1 compatibility timer should be a single, separate - timer, not a per-group timer. - - net/mld: Group may be NULL when sending a general query - - From Gregory Nutt (2018-11-11). - * net/mld: Fix logic error when testing for the case where all members - have left the group.

It takes time to switch to the target task after - g_readytorun has been modified. If panic/assert happen during this - period, the dump will contain the incorrect and confusing information due - to the difference between the real running task and the return value of - this_task(). This change resolve this problem by adding g_running_task to - track the real running task through the context switch.

From Juha Niskanen - (2018-11-16). - * fs/dirent: Corrects a problem with opendir() noted by Petteri Aimonen in - Bitbucket Issue 132: "opendir() fails for FAT filesystem with trailing - slash in path". I see the following behaviour on NuttX 7.26, where I - have SD card mounted on /flash and a directory called "frm" on it: - - opendir("/flash") returns (DIR *) 0x1000c580 - opendir("/flash/") returns (DIR *) 0x1000c5d0 - opendir("/flash/frm") returns (DIR *) 0x1000c620 - opendir("/flash/frm/") returns (DIR *) 0x0 - - From POSIX specs for opendir(): "A pathname ... that ends with one or - more trailing slashes shall be resolved as if a single dot character - ( '.' ) were appended to the pathname." - - So for mount points, opendir() works correctly, but for FAT32 filesystem - it fails to open directory if the path has a trailing slash... - - NOTE: You would not see this problem if you call opendir() indirectly in - NSH (like 'ls -R /') because NSH contains logic to remove trailing '/' - characters from paths.

It takes the same - parameters as arch_invalidate_dcache(), but performs invalidation of only - the lines in cache that need to be invalidated. This new function could - be used as a a direct replacement for arch_invalidate_dcache(). - - The user of this invalidation are mmcsd_sdio currently. The mmcsd_sdio - driver makes calls for dcache invalidation through the chip specific - architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 - chips to use arch_invalidate_dcache_by_addr() instead of - arch_invalidate_dcache(). - - This commit includes additional changes to mmcsd_sdio.c. I created - SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into - mode dcaches after the DMA transfer. I have been using - SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems - that I previously reported regarding non-cache aligned buffer - invalidation errors (for my store-through dcache). However, it does not - permit use of unaligned DMA buffers for store-into mode dcaches. - - SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file - selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the - stm32f7 chips to select it. From Bob Feretich (2018-11-20). - * All network drivers!

From Gregory Nutt (2018-11-25). - * sched/irq and sched/sched: Measurement of interrupt handler duration - used to be available only in Tickless mode since it used the high - resolution Tickless timer to measure interrupt time. This commit adds - CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the - interrupt duration calculation to use the same high-resolution, - platform-specific timer as is used with the Critical Section Monitor. - This leads to two improvements: (1) You can now measure interrupt - duration in non-Tickless mode, and (2) in either mode, the interrupt - duration and the critical section measures will use the same - high-resolution timer and should, therefore, never be any discrepancy due - to different clock sources.

From Dave Marples (2018-12-02). - * include/nuttx/wireless/bluetooth and include/nuttx/wireless/bluetooth: - Add SIOCBTCONNECT and SIOCBTDISCONNECT ioctl commands From Lwazi Dube - (2018-12-02). - * arch/arm/src/stm32/stm32_adc.c: Refactor adc_reset. It should be easier - to maintain this code if it's divided into smaller functions From - Mateusz Szafoni (2018-12-02). - * arch/arm/include/tiva: Started integration of support for the CC13x0, - CC13x2, and CC26x2. From Gregory Nutt (2018-12-03). - * tools/detab.c: Add detab.c which will convert all tabs in a file to - spaces. From Gregory Nutt (2018-12-03). - * tools/lowhex.c: Add lowhex.c that will convert hexadecimal constants in - a file to use lower case representation. From Gregory Nutt (2018-12-03). - * STM32F7, STM32H7, and STM32L4: Port Dave Marples STM32 fix to other - STM32 SPI drivers From Gregory Nutt (2018-12-03). - * configs/launchxl-cc1312r1/: Add a configuration for the - LAUNCHXL-CC1312R1 board. This is a very stripped down configuration. It - was needed to support verification of the CC13xx configuration logic and - will be needed to support completion of the CC13xx port. From Gregory - Nutt (2018-12-03). - * arch/: In the current implementation we only use very high priority - interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but that means - there are loads of lower priority ones that are effectively unused. I - have *not* changed the semantics of these levels but have 'shifted' them - to be based around the midpoint of the available interrupts (0x80) rather - than at the top end....that allows for interrupts to be defined above - (or, indeed, below) them as needed by the application. This should have - no functional effect on existing code but adds in a clean capability to - define higher priority interrupts. From Dave Marples (2018-12-03). - * arch/arm/src/stm32f0/stm32f0_clockconfig.c: Fixes the problem in GPIO - port clocks. Only port A clock was enabled although the comment states - otherwise. From Juha Paalijärvi (2018-12-04). - * arch/arm/src/tiva: Remove option CONFIG_TIVA_BOARD_CLOCKCONFIG. It is - not used and unnecessary. Fix some naming. up_clockconfig() is - inappropriate. Change tiva_clockconfig() to tiva_clock_reconfigure() - then we can change up_clockconfig() to tive_clock_configure(). From - Gregory Nutt (2018-12-04). - * arch/arm/include/stm32/chip.h: Remove redundant STM32 family - definitions. It is already done in arch/arm/src/stm32/Kconfig From - Mateusz Szafoni (2018-12-05). - * stm32f7: I2C out of bounds access on priv->msgv. Error in if statement. - It was checking for msgc > 0. If message count is 1, only index 0 is - valid on priv->msgv. Therefore random values in memory were used to set - next_norestart. From David Sidrane (2018-12-05). - * STM32H7 and STM32L4: Applied David Sidrane's I2C to - arch/arm/src/stm32h7/stm32_i2c.c and arch/arm/src/stm32l4/stm32l4_i2c.c. - Those easy because F7 patch applied with no problem (after changing path - and file names appropriately). The patch could not be applied to the - following. The logic is different. I don't know if a similar change is - needed there or not. - - arch/arm/src/stm32/stm32f30xxx_i2c.c - - arch/arm/src/stm32/stm32f40xxx_i2c.c - - arch/arm/src/stm32/stm32_i2c.c - - arch/arm/src/stm32/stm32_i2c_alt.c - - arch/arm/src/stm32f0/stm32f0_i2c.c - From Gregory Nutt (2018-12-05). - * arch/arm/src/armv7-m: This commit changes the lazy and non-lazy - exception handler to remove a couple of cpsid instructions from them on - ARMv7-m. If my understanding is correct then these interrupt - manipulations aren't doing anything anyway because prioritization stops - secondary interrupts arriving and, even if they did work, they would have - introduced race conditions for the period of time between the interrupt - arriving and further interrupts being disabled. From Dave Marples - (2018-12-06). - * arch/arm/src: Remove all driver-specific logic to set the interrupt - priority. There is no good reason to change the interrupt priority - unless you just want to debug a difficult problem. OR if you want to use - high priority interrupts. In that case the specific interrupt priorities - will need to be set by board-specific logic. From Gregory Nutt - (2018-12-06). - * fs/cromfs/fs_cromfs.c: Fixes hardfault From David Sidrane (2018-12-06). - * libs/libc/stdio/lib_libfread.c: fread() should always set EOF if fewer - than the requested number of bytes was not read. Per Anthony Merlino. - From Gregory Nutt (2018-12-07). - * arch/mips/include/pic32mz/chip.h: Add a missing " in an error message. - From Ouss4 (2018-12-07). - * arch/mips/src/pic32mz: Add support for the I2C bus. From Ouss4 - (2018-12-07). - * arch/arm/src: In most I2C drivers, correct upper index value in I2C - trace dump. Eliminates the extra NONE event from the trace dump output. - From Ouss4 (2018-12-08). - * wireless/bluetooth and include/nuttx/wireless/bluetooth: Remove - unnecessary gatt ioctls From Lwazi Dube (2018-12-08). - * STM32F3 and STM32F4 I2C: Remove the extra NONE event from the trace dump - output. From Ouss4 (2018-12-08). - * STM32 I2C (alternate): Remove the extra NONE event from the trace dump - output. From Ouss4 (2018-12-08). - * Improvements in STM32 ADC: - - arch/arm/src/stm32/stm32_adc.c: Start conversion on startup is now - possible if TIM triggering selected. This can be useful to start ADC - TIM conversion for ADC IPv2 when opening ADC device. - - arch/arm/src/stm32/stm32_adc.c: Fix compilation errors for chips with - one ADV TIM - - configs/nucleo-f303re: Refresh ADC example - - configs/nucleo-f334r8: Refresh ADC example - From Mateusz Szafoni (2018-12-09). - * configs/nucleo-f334r8: Add example for the SPWM generation (custom STM32 - PWM usage). From Mateusz Szafoni (2018-12-09). - * arch/arm/src/stm32/stm32_pwm: Fix compilation errors if the upper-half - PWM logic is not enabled. From Mateusz Szafoni (2018-12-09). - * include/nuttx/drivers/pwm.h: Remove dependency on CONFIG_PWM for the - upper-half PWM header. This allows compilation for the lower-level PWM - drivers even if the upper-half PWM logic is not used. From Mateusz - Szafoni (2018-12-09). - * arch/arm/src/stm32/stm32_tim.c: Fix compilation error if there is no - TIM8. From Mateusz Szafoni (2018-12-09). - * configs/nucleo-f334r8/highpri: Remove the upper-half ADC from - configuration. From Mateusz Szafoni (2018-12-09). - * configs/nucleo-f302r8/highpri: Remove the upper-half ADC from - configuration. From Mateusz Szafoni (2018-12-09). - * configs/stm32f429i-disco/highpri: remove the upper-half ADC from - configuration From Mateusz Szafoni (2018-12-09). - * include/nuttx/net/arp.h: Fix whitespace after ARPHRD_IEEE80211 From - Daniel Agar (2018-12-09). - * fs/vfs: dup() and dup2() were broken some time back. fs_dupfd() was - return returning OK on success, not the file descriptor of the duplicated - fd. From David Sidrane (2018-12-10). - * drivers/wireless/bluetooth/bt_uart_cc2564.c: Add cc2564 driver. From - Lwazi Dube (2018-12-11). - * drivers/1wire/ds28e17.c: Optimize I2C write followed by read to same - address. From Juha Niskanen (2018-12-11). - * arch/arm/src/stm32/Kconfig: Simplify ARM core selection logic From - Mateusz Szafoni (2018-12-12). - * drivers/mtd/at25.c: Added support for AT25DF081A serial flash chip. - From Marc Rosen (2018-12-12). - * fs/nxffs/nxffs_ioctl.c: Pass unrecognized IOCTL commands to the - contained MTD driver. From Daniel P. Carvalho (2018-12-12). - * arch/arm/src/stm32/Kconfig: USB Host is an option. From David Sidrane - (2018-12-12). - * drivers/mtd/at25.c: Fixed missing opening parenthesis. From Marc Rosen - (2018-12-13). - * gencromfs.c:1171:3: warning: ignoring return value of 'asprintf', - declared with attribute warn_unused_result [-Wunused-result]. From David - Sidrane (2018-12-13). - * arch/arm/src/tiva/common/tiva_hciuart.c: Port bluetooth HCI uart - interface from stm32 to tiva From Lwazi Dube (2018-12-15). - * arch/arm/src/stm32f0l0: Rename stm32f0 to stm32f0l0 to make a space - for STM32 L0. Rename files, functions and defines, removing the f0_ - from the names in order to make them MCU agnostic. From Gregory Nutt - (2018-12-16). - * Numerous files: Fixes usage of CONFIG_BIG_ENDIAN; should be - CONFIG_ENDIAN_BIG From Anthony Merlino (2018-12-16). - * net/sixlowpan: Fixes decompression of ipaddr from MAC address. The - logic used to populate the IP from the radio address should match - sixlowpan_ipfromsaddr/sixlowpan_ipfromeaddr From Anthony Merlino - (2018-12-16). - * Fix lc823450 related: - - configs/lc823450-xgevk: Fix IOB params in rndis/defconfig. These - prameters work for HTTP audio streaming. - - arch/arm/src/lc823450: Fix up_allocate_heap() in - lc823450_allocateheap2.c. This change fixes heap size and also - implements up_addregion(). From Masayuki Ishikawa (2018-12-18). - * sixlowpan: Fixes logic surrounding the Universal/Local bit. This bit - represents whether the IID is locally/globally administered. The U/L - bit is bit 1 of the MSB of the EUI-64. It should only be inverted in - cases where there is a full EUI-64. In cases where the IID is derived - from say, a short address, this bit should be forced to 0, indicating - that it is locally administered. See: - - https://tools.ietf.org/html/rfc4291#section-2.5.1 - - https://tools.ietf.org/html/rfc4944#section-6 - - https://tools.ietf.org/html/rfc2464#section-4 - From Anthony Merlino (2018-12-18). - * sched/task/task_spawn.c: Correct description of input parameters to - task_spawn_exec(). Noted by: JeongchanKim From Gregory Nutt - (2018-12-18). - * sixlowpan/ieee802154: IEEE802.15.4 stores and uses addresses in little - endian order. From Anthony Merlino (2018-12-18). - * crypto/aes.c: This commit provides an improved AES cipher API in - addition to the existing routines. The reasons for this new API are: - 1) better performance, giving the possibility to avoid re-setting-up - the key for each AES block when the same key is used multiple times. - This is important for the current single user of AES, which is related - to storage and FTL. And 2) suitable for simultaneous use of multiple - AES keys, which will be required by the upcoming crypto framework. It - retains compatibility with the previous API, so there is no need to - change anything else right now. From Sebastien Lorquet (2018-12-18). - * arch/ assertions: Correct duplicated logic from commit - dbf01d12b7321d1b48b68d3b69842a853b049376. Checking for PID == zero is - not a valid way to test for the IDLE task in all configurations! This - is only true in the single CPU configuration. In multiple CPU - configurations, there will be a separate IDLE task for each CPU with a - different PID and an alternative check must be used. NOTE: The logic - fixed in somes places still lacks sufficient intelligence to find the - right stack for the CPU IDLE thread and could still show the wrong - stack. From Gregory Nutt (2018-12-18). - * Change RNDIS mac: - - configs/lc823450-xgevk: Change RNDIS MAC address assignment. In - previous implementation, mac[0] was assigned to 0xaa for RNDIS host - to avoid MAC address conflicts with RNDIS device.. However, I - noticed that this assignment causes a random MAC address generation - on ubuntu16.04 or later which is inconvenient to set up network - interface. This new assignment scheme fixes this issue. - - configs/viewtool-stm32f107: Change RNDIS MAC address assignment. - Same issue. - From Masayuki Ishikawa (2018-12-19). - * crtypo/: This change: - - Avoids the use of up_aesinitialize() entirely, which resolves - dependency problems, because this function does not make sure that an - actual hardware aes implementation was made available: each SoC is - now responsible to ensure the AES hardware is initialized before - first use. This applies to lpc43xx, stm32 and sam34. - - Remove definitions of the NEVER used aes_init and aes_update - operations. The new AES API will be more suitable. - - Change the unusual naming in stm32 (avoiding possible naming clashes) - - Change the unusual naming in sam34 (avoiding possible naming clashes) - - Add some FAR to pointers and enforce the 80 col limit in stm32 and sam - From Sebastien Lorquet (2018-12-19). - * arch/arm/src/stm32: Add support for DMA v1 CSELR support. From - Mateusz Szafoni (2018-12-19). - * Brings in initial WIP support for the STML0. This initial commit is - unverified and, hence it it marked "EXPERIMENTAL." From Mateusz - Szafoni (2018-12-19). - * configs/: Hook new STM32L0 boards into the configuration system. - nucleo boards use as default ST LINK MCO as clock input from MCU and - for this HSEBYP must be enabled - - configs/nucleo-l073rz: Add basic support for nucleo-l073rz - - configs/b-l072z-lrwan1: Add basic support for b-l072z-lrwan1. - From Mateusz Szafoni (2018-12-19). - * sixlowpan: Address comment regarding avoiding double lookup of address - context. From Anthony Merlino (2018-12-19). - * Revert "This patch prevent heap corruption as in below case." This - solution to the problem noted by EunBong Song results in major memory - fragmentation and and out-of-memory conditions on the PX4 platform. On - that platform the lower priority work queue is very low priority and - essentially never runs when the system is busy. As a result, the - systems gets slowly starved of memory until failures and bad behaviors - begin to occur. This reverts commit - 91aa26774b291fa553f701ce5222e56a6156c323. From Gregory Nutt - (2018-12-20). - * mm/mm_heap/mm_sem.c: This is a candidate replacement for the reverted - change 91aa26774b291fa553f701ce5222e56a6156c323. This change adds a - check to mm_trysemaphore() (the root implementation of both - kmm_trysemaphore() and umm_trysemaphore()). It checks if the that task - that is apparently executing is marked as RUNNING. If not, how could - the non-running task be trying to get the MM semaphore? I think only - in the exact scenario that Eunbong Song has described. So I think the - solution should provide the same protection as - 91aa26774b291fa553f701ce5222e56a6156c323 but without the horrific - consequences to memory usage. From Gregory Nutt (2018-12-20). - * sched/Kconfig and sched/init/os_bringup.c: Allow the init task - priority to be set. From David Sidrane (2018-12-20). - * arch/arm/src/stm32/chip/stm32_dma_v1.h: Add missing DMA channel - configuration. - * mm/mm_heap/mm_sem.c: Defer freeing if mm is held by a not running - task. When the holder is running we can add a holder count. If there - is no holder OR it is not running we want to try to take the semaphore. - There will not be a count if the task is the holder and not running - because it already holds the count. This will result it the deferred - free. We will take it when not held and do the free when we can get - the count because there was no holder. From David Sidrane (2018-12-20). - * Extends the MTD configdata device with the following features / - additions: - 1. Configurable option to use named config items instead of enumerated - ID/Instance numbers. - 2. Ability to iterate through the existing configdata items in the - /dev/config device. - 3. Ability to "unset" a configdata item. - 4. Ability to perform "flash_eraseall" on the /dev/config device. - From Ken Pettit (2018-12-20). - * drivers/analog/lmp92001.c: Add support for the TI LMP92001 device. - * arch/arm/src/samd2l2/sam_i2c_master.c: Corrects behavior of the - I2C_M_NOSTART flag. Also adds a release a bus on RXNACK and corrects - typo priv->flags to msg->flags as priv->flags is never set. From - Alexander Vasiliev (2018-12-22). - * arch/arm/src/samd5e5/sam_i2c_master.c: Alexander Vasiliev's fix to the - SAMD21 I2C Master (commit b1110ba91c549572e94c24ebed202643233deee3) - should probably also be applied to the SAMD51 I2C Master which is - identical. From Gregory Nutt (2018-12-22). - * Fix lc823450 start: - - arch/arm/src/lc823450: Use CONFIG_STACK_COLORATION instead of - CONFIG_DEBUG_STACK - - arch/arm/src/lc823450: Fix go_os_start() in lc823450_start.c. I - found a bug in go_os_start() that it returns immediately because it - does not compare r1 to zero. This commit fixes this bug. Also, this - commit fixes its description. - From Masayuki Ishikawa (2018-12-25). - * arch/arm/src: Masayuki Ishikawa's change to go_os_start() should be - applied to all MCU-specific start-up functions that support - go_os_start(). From Gregory Nutt (2018-12-25). - * configs/stm32f4discovery: Add loadable app build support in - Make.defs From Masayuki Ishikawa (2018-12-25). - * arch/arm/src/samd2l2/chip: Adds a complete ADC header file for SAMD21 - and a partially complete ADC header file for the SAML21. From - Alexander Vasiliev (2018-12-26). - * net/sixlowpan: Record and restore d_buf on entry/exit of - sixlowpan_input. This avoids an issue where d_buf gets set to NULL by - sixlowpan, and then is used by forwarding logic from another network - interface before getting set back to the drivers internal b From - Anthony Merlino (2018-12-26). - * tools/gencromfs.c: Fix build on macOS From David Sidrane (2018-12-26). - * sched/pthread: Implement pthread_key_delete(). This involves some - minor changes to the group data structure. From Gregory Nutt - (2018-12-28). - * arch/arm/src/imxrt/chip/imxrt106x_pinmux.h: Add FLEXCAN3 to pinmux. - From David Sidrane (2018-12-28). - * arch/arm/src/tiva/: Add support for LM3S9B92. From Lwazi Dube - (2018-12-28). - * Add some conditional compilation to logic added with commit - 1cf992ed04c230e639bf29e55f2ec110cb9c4340 to better 'idiot-proof' the - LM3S support. From Gregory Nutt (2018-12-28). - * arch/arm/src/samd2l2, configs/samd20-xplained, samd21-xplained, - saml21-xplained: Fix SAMD2L2 arch to use calibrated oscillator value. - Now SAMD20 and SAMD21 should work fine without external crystal. Note - that SAML21 Xplained board has an external crystal and doesn't need - this change, unless you don't want to use the crystal. From Alexander - Vasiliev (2018-12-29). - * drivers/mtd/smart.c: Fix smart_write_alloc_sector sector size - calculation. From Daniel P. Carvalho (2018-12-29). - * mm/mm_heap/mm_sem.c and sched/task/task_getpid.c: Commits - 43d37c866bdaefeff659dec20ed380389c4880d5 and - f37202cbc0f72526ecfa58e5d27c5b4973289140 resolved some problems with - the original fix of 91aa26774b291fa553f701ce5222e56a6156c323. However, - Those changes used an internal OS interface (sched_self()) which is not - available when the the user-space memory manager is built in the - PROTECTED or KERNEL builds and resulted in build failures. This commit - repartitions the logic by moving some of the changes from mm_sem.c into - task_getpid.c. The logic is equivalent for the case of - mm_trysemaphore(), but now has wider impact (since it potentially - affects all callers of getpid()). Hence, this change may also - introduce some other issues that will need to be addressed. From - Gregory Nutt (2018-12-30). - * arch/arm/src/samd2l2/sam_i2c_master.h: Export - sam_i2c_master_initialize(int bus) to be used by board config. From - Alan Carvalho de Assis (2018-12-30). - * drivers/eeprom/i2c_xx24xx.c and include/nuttx/eeprom/i2c_xx24xx.h: Add - support to Microchip AT24CM02 From Alan Carvalho de Assis (2018-12-30). - * configs/saml21-xplained/include/board.h: Fix removed MAXCOARSESTEP - from saml21-xplained board From Alan Carvalho de Assis (2018-12-30). - * arch/arm/src/tiva/common/lmxx_tm4c_gpioirq.c: Fix tiva gpio - interrupts From Lwazi Dube (2018-12-30). - * configs/: Commit fd68d74264c breaks all STM32 board configurations - that use STM32 USB host.

That was due in part to commit - 19e16cb which extended up_netinitialize() with a - !defined(CONFIG_NETDEV_LATEINIT) guard but did not add the guard to - concrete implementations. I say "in part" because I don't think that - the original intent of commit 19e16cb was to enable an alternative - initialization of MCU internal Ethernet support but rather to enable - support of external Ethernet devices that may have dependencies on, for - example, SPI.

From - David Sidrane (2019-01-30). - * arch/arm/src/samv7/sam_emac.c: The logic for determining the number of - queues for SAMV71 must be extended. All SAMv7 parts increase the - number of queues from 3 to 6 at revision B, not just the SAMV71. From - Gregory Nutt (2019-02-01). - * arch/arm/src/samv7/sam_emac.c: Fix a compile problem introduced with - commit cf1e0f79762284da2df372fe80eb3eca09488e24. From Gregory Nutt - (2019-02-01). - * arch/arm/src/samv7/sam_emac.c: Fixes rxdesc index logic to handle - Buffer Not Available (BNA) condition. - - If a SOF is found, but no EOF, don't move past the frame. Instead, - keep the index at the SOF buffer until the rest of the data is written. - - This fixes a receiver lockup condition where the peripheral and this - driver get out of sync with there head pointers. In this case the - driver has moved past buffers it owns, without clearing ownership, - which results in the peripheral and driver in a deadlock with each - other. - - From Anthony Merlino (2019-02-02). - * arch/arm/src/sam34 and sama5: Port Anthony Merlino's fix to similar - Ethernet drivers for parts in other SAM families. From Gregory Nutt - (2019-02-02). - * arch/mips/src/pic32mz: Add support for the PIC32MZ timers (driver, - lowerhalf, freerun and oneshot) From Abdelatif Guettouche (2019-02-02). - * sched/signal/sig_deliver.c: Restructure nxsig_deliver() so that the - signal handler is not called with the pre-emption disabled (or, at - least no with pre-emption disabled by nxsig_deliver() itself). From - Gregory Nutt (2019-02-03). - * sched/sched: Rename all internal, static functions from sched_* to - nxsched_* to indicate that they are NuttX internal functions. This is - only a start. Eventually, need to rename all sched_ functions - prototyped in sched/sched/sched.h and in include/nuttx with nxsched_. - From Gregory Nutt (2019-02-03). - * arch/ Signals: The saved return register state is available on the user - stack. Thic commit reorders some logic so that certain, critical - registers are preserved in the TCB. This does not make the logic 100% - secure, but does prevent some obvious things. - sched/signal/sig_delivery: Add a flag to the TCB to indicate that we - are in a signal handler. Use this flag to assure that a there a never - attempts to nest signal handling operations on a thread. This was - guaranteed before but when locking of pre-emption during signal - delivering was eliminated in a previous commit, there was a remote - possibility of an attempt to do nested signal handling. This flag - assures that there is only one signal handled at a time. From Gregory - Nutt (2019-02-03). - * This commit renames all internal OS functions defined under sched/task - so that they begin with the prefix. For example, nxtask_exit() vs. - task_exit(). From Gregory Nutt (2019-02-04). - * - sched/init/nx_bringup.c: Fix a naming collision. - - sched/init: Rename os_start() to nx_start() - - sched/init: Rename os_smp* to nx_smp* - - sched/init: Rename os_bringup to nx_bringup - - sched/init: rename all internal static functions to begin with nx_ - vs os_ - From Gregory Nutt (2019-02-04). - * graphics/nxmu/nxmu_start.c: Fix a naming collision introduced with the - last commit. Ye olde nx_start that started the NX graphics is now - nxmu_start(). - include/nuttx/nxmu.h: Due the name change, the nxmu_start() belongs - more appropriately in nxmu.h than nx.h. From Gregory Nutt (2019-02-04). - * include/nuttx/nx/nxmu.h: This header file could be lethal; it declared - an #error if CONFIG_DISABLE_MQUEUE=y. From Gregory Nutt (2019-02-04). - * libs/libc/unistd/lib_getopt.c: Add logic to reinitialize the stale - context for the FLAT/PROTECTED builds. In these builds getopt() global - varriables may be shared by many tasks. If any task exits the getopt() - loop before all command line arguments have been parsed, then getopt() - global variables will be left in a bad state. The next time getopt() - is called, this logic should detect the bad state and force the state - of getopt() to be re-initialized so that it can be reused. This logic - is not full proof (it would fail, for example, if you tried to parse - the same command line twice) but should catch the typical misuse - cases. From Xiang Xiao (2019-02-05). - * drivers/ioexpander/tca64xx.c: Fix some errors in the TCA64XX driver. - From Bruno Schwander (2019-02-06). - * configs/stm32f769i-disco/src/stm32_appinitialize.c: Florian R. - Hölzlwimmer reports that stm32_appinitialize.c often has missing OK and - NULL definitions. This should be fixed by including sys/types.h where - they are defined. From GregoryN (2019-02-06). - * libs/libc/stdio: Add newlib-nano fprintf as an option. This fprintf - code was originally adapted from AVR libc and provides improved - floating point output support, including 'g' mode and making 'f' mode - include digits past the decimal by default. However, this version does - not have any long long support. On a demonstration cortex M4 build, - this version saves about 5kB of ROM. The newlib version can be found - here: https://salsa.debian.org/electronics-team/toolchains/newlib-nano - . That project is GPL overall, but the newlib-nano printf portions are - BSD licensed as described in the COPYING.NEWLIB file. From Keith - Packard (2019-02-06). - * - arch/misoc/src/minerva: Add support for the Minerva architecture - - configs/Kconfig and misoc/nsh/defconfig: Add support for the - Verilator board. - From Ramtin Amin (2019-02-07). - * tools/lowhex.c: Fix an initialization problem that was causing some - odd behavior at the beginning of lines. From Gregory Nutt (2019-02-07). - * tools/rmcr.c: Add a tools to remove carriage returns and dangline - whitespace at the end of lines. From Gregory Nutt (2019-02-07). - * tools/nxstyle.c: Can now detect if the C comment closing is not on a - separate line. From Gregory Nutt (2019-02-08). - * tools/nxstyle.c: Make sure that all files begin with a comment on line - 1 (which should be the file header). From Gregory Nutt (2019-02-08). - * include/: Correct naming of standard header file. Should be dlfcn.h, - not dllfcn.h. From Gregory Nutt (2019-02-09). - * configs/launchxl-cc1312r1: Add support for on-board LEDs and buttons. - From Gregory Nutt (2019-02-10). - * configs/launchxl-cc1310: Clone LED and button support from the - launchxl-cc1312r1. The number of LEDs and buttons as well as DIO usage - is identical. From Gregory Nutt (2019-02-10). - * drivers/usbhost/usbhost_cdcacm.c: Fixes to the IOCTL method in - recovery of UART pointer and in names of Termios-related field. From - xhbm (2019-02-11). - * CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file - system. NuttX with no file system does not make sense and is no longer - supported. From Gregory Nutt (2019-02-11). - * configs/sama5d2-xult: Move console from FLEXCOM4 to UART1. FLEXCOM4 - does not work for the Arduino serial. UART1 is used with the VCOM - provided by the EDBG. From Gregory Nutt (2019-02-11). - * Fix conditional logic: The setup seems to support a network without - sockets (CONFIG_NSOCKET_DESCRIPTORS == 0). That is not the case; if - the network is enabled, sockets must be provided. From Gregory Nutt - (2019-02-11). - * configs/launchxl-cc1312r1: Correct DIOs used to provide the UART0 - serial console. Board boots to NSH prompt now. But I am not getting - serial input. Things are probably not very stable in general. From - Gregory Nutt (2019-02-12). - * sched/: Remove the option CONFIG_BOARD_INITTHREAD. Now, if - CONFIG_BOARD_INITIALIZE is selected, then the board_initialize() logic - will ALWAYS run on an internal kernel thread. This will prevent the - problems people have had doing inappropriate board_initialization on - the IDLE thread. From Gregory Nutt (2019-02-12). - * arch/arm/src/tiva: The LauchXL-CC1312R1 NSH configuration is now fully - functional. On to bigger and better things. From Gregory Nutt - (2019-02-13). - * - Move vscanf logic to lib_sscanf.c Switched to stream interface - (tricky, because the old implementation used massive read ahead, which - isn't suitable for streams, chars already read are gone). - - Added scanf and fscanf - - Added hh, h, and ll modifiers - - Fixes for standard compliance in scanf - - Fixes for standard compliance in strto... function family (don't - consume single '-' or '+', allow sign in strotul(l)) - From Johannes (2019-02-14). - * net/tcp/tcp_send_buffered.c: Fix assertion crash when window size is - zero. From Gregory Nutt (2019-02-14). - * net/: The value ERROR should never be returned from internal OS - functions. That is reserved for returning values to appliations with - the errno value set. Within the OS, errors are returned with a negated - errno value ALWAYS. From Gregory Nutt (2019-02-14). - * libs/libc/stdio/lib_libsscanf.c: Initialized the lastc pointer to avoid - the checks for NULL. Removed a bug in the floating point parsing which - allowed several signs after each other. From Johannes (2019-02-14). - * tools/nxstyle.c: Add check for multiple definitions of local variables - on a line. From Gregory Nutt (2019-02-14). - * libs/libc/stdio/lib_libvsprintf.c: No precision specifier resulted in - precision 0 but should be precision 6. From Johannes (2019-02-15). - * libs/libc/stdio: Add support for %g format which, for these purpose, - is equivalent to %f except that trailing zeroes are suppressed. From - Gregory Nutt (2019-02-15). - * libs/libc/stdio: In the recent changes we lost the implementation of - vsscanf(). This commit restores vsscanf(). sscanf() is not just a - front end for vsscanf(). From Gregory Nutt (2019-02-15). - * libs/libc/stdio: Remove unused, non-standard functions lib_sscanf() - and lib_sprintf(). From Gregory Nutt (2019-02-15). - * libs/libc/stdio/nano_libvsprintf.c: Add long long support. - CONFIG_LIBC_LONG_LONG needs at least CONFIG_NANO_PRINTLEVEL 2. Code - size for compile without CONFIG_LIBC_LONG_LONG shouldn't be affected. - From Johannes (2019-02-15). - * nuttx/sched/mqueue: Change 'int prio' to 'unsigned int prio'. - According to open group specification, priority field in mq_* functions - should have unsigned type: - http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/mqueue.h.html - From Michał Łyszczek (2019-02-15). - * arch/arm/src/tiva/hardware: Add CC13x0 and CC13x2 I2C header files. - From Gregory Nutt (2019-02-16). - * syscall/syscall.csv: Change to mqueue function protothypes must be - reflected in the KERNEL mode proxies as well. From Gregory Nutt - (2019-02-16). - * libs/libc/stdio/Make.defs: lib_dtoa.c is only used in the - LIBC_CONFIG_NANO_PRINTF=n case. From Johannes (2019-02-16). - * Restore lib_sprintf(). It was removed because I thought was not used. - But I was wrong; there is logic in drivers/syslog that depends on - lib_sprintf(). From Gregory Nutt (2019-02-16). - * arch/arm/src/tiva/hardware/tiva_wdt.h: Add WDT register definition - header file for all LM, Tiva, and CC13xx parts. From Gregory Nutt - (2019-02-16). - * - arch/arm/src/stm32f0l0: SPI support for F0 - - arch/arm/src/stm32f0l0/Kconfig: L0 parts should select - STM32F0L0_STM32L0 - - arch/arm/src/stm32f0l0/hardware: unify names for ADC/DAC/DMA/CAN - - drivers/wireless/lpwan/sx127x/sx127x.c: return immediately when ISR0 - is called but sx127x is not initialized - - configs/nucleo-f091rc: support for sx127x - - configs/b-l072z-lrwan1/include/board.h: use HSI as default clock - source and fix typo in SPI1 pins. - From Mateusz Szafoni (2019-02-16). - * libs/libc/stdio/lib_dtoa.c: Lots of risky turmoil to get this file - closer to the NuttX coding style. Seems to check out, but still - risky. libs/libc/stdio/lib_libdtoa.c: A fix for the %g format. The - algorithm will sometimes generate number greater than the precision of - type double. This adds a check if the precision has been exceeded and - logic to remove the least significant garbage. From Gregory Nutt - (2019-02-16). - * libs/libc/stdio/nano_libvsprintf.c: Added hh type modifier (without - extending the flag variable). From Johannes (2019-02-17). - * tools/nxstyle.c: Beef up logic that detects multiple variable - definitions per line. From Gregory Nutt (2019-02-17). - * libs/libc/stdio: This commits makes the nano-printf the defualt logic - for the printf family. The legacy printf is still available via - CONFIG_LIBC_PRINT_LEGACY. This commit also modifies the nano-prinf - configure: The PRINT_LEVEL is not long selectable. Instead, a not - CONFIG_LIBC_PRINT_MINIMAL boolean setting was added and the PRINT_LEVEL - is derived from a combination of CONFIG_LIBC_PRINT_MINIMAL, - CONFIG_LIBC_FLOATINGPOINT, and CONFIG_LIBC_LONG_LONG. From Gregory - Nutt (2019-02-17). - * libs/libc/stdio: Rename lib_dtoa.c to legacy_dtoa.c; rename - lib_libvsprint.c to legacy_libvsprintf.c From Gregory Nutt (2019-02-17). - * libs/libc/stdio: Rename all nano_*.c and nano_*.h files to lib_*.c and - lib_*.h to emphasize that these are now the defaults, not an optional - implementation. From Gregory Nutt (2019-02-17). - * arch/xtensa/src/esp32/esp32_timerisr.c: Fix backward comparison. From - Gregory Nutt (2019-02-17). - * libs/libc/stdio/lib_libvsprintf.c: Adds configurable support for - numbered arguments. From Johannes (2019-02-18). - * libs/libc/stdio/Kconfig: Need to guard LIBC_NUMBERED_ARGS against - LIBC_LEGACY_PRINTF From Johannes (2019-02-18). - * - sched/init/nx_start.c: Add support for - CONFIG_BOARD_DRIVER_INITIALIZE. If this option is selected then - nx_start() will call a board-provided function board_early_initialize() - immediately after calling up_initialize(). - - Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE. - - Rename board_initialize() to board_late_initialize() - From Gregory Nutt (2019-02-18). - * include/nuttx/compiler.h: Important fix for C++ users. compiler.h was - using the value of __STDC_VERSION__ to determine if inline functions - are supported or not. If not then the keyword inline was defined out. - Good for C but bad for C++ because C++ does not defined - __STDC_VERSION__ at all. C++ applications may draw in compiler.h - indirectly via other head files and this can result in C++ compiler - problems since 'inline' is defined out. This fix is to ignore the - (undefined) __STDC_VERSION__ if __cplusplus is defined. From Gregory - Nutt (2019-02-19). - * include/nuttx/elf.h: Adds missing extern "C" __cplusplus guard. From - Anthony Merlino (2019-02-19). - * libs/libc/stdio/lib_libvsprintf.c: Cleaned naming and allow for leading - zeros in argument number (which doesn't make sense but should be). - From Johannes (2019-02-19). - * arch/arm/src/stm32f7/stm32_i2c.c: Fix another memory access issue on a - bus error. From David Sidrane (2019-02-19). - * arch/arm/src/stm32h7 and stm32l4: Apply David Sidrane's fix for the - STM32F7 to the STM32L4 and STM32H7. The same change might be - appropropriate to STMF0/LO and STM32, but the patch does not apply - cleanly. It would have to be manually checked. From Gregory Nutt - (2019-02-19). - * libs/libc/stdio/Kconfig: CONFIG_LIBC_NUMBERED_ARGS now depends on - EXPERIMENTAL. Per Johannes: I tested numbered arguments on i.mx rt - 1050, and it isn't working. Only on Linux/MSYS 64bit all relevant data - types are size 8 bytes, and therefore my loop through the arg list is - working. On 32bit systems, all is 4 bytes except floating point - variables which is implicit 8 byte double. From Gregory Nutt - (2019-02-20). - * libs/libc/stdio/lib_libvsprintf.c: Fix typo: PRINTF_LEVEL, not - PRINT_LEVEL. From Gregory Nutt (2019-02-20). - * - libs/libc/stdio/lib_vsprintf.c and Kconfig: Numbered arguments now - work by using two pass parsing and an argument list. The maximum - number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX which - is then copied into NL_ARGMAX. Size of pointer argument ('p') is - determined before output. - - include/limits.h: Define NL_ARGMAX (as well as some of the other - 'invariant values' per - http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html) - From Johannes (2019-02-21). - * libs/libc/lib_libvsprintf.c and Kconfig: Remove - CONFIG_LIBC_PRINT_MINIMAL. The output in that configuration is - unsatisfactory and inappropriate for use with NuttX. For example, the - output from many NSH commands become corrupted and useless. Doesn't - belong in this context. From Gregory Nutt (2019-02-21). - * libs/libc/stdio/Kconfig: Add 'range 9 999999' to - CONFIG_LIBC_NL_ARGMAX. Per OpenGroup.org, the minimum value for - NL_ARGMAX is 9. From Gregory Nutt (2019-02-21). - * include/poll.h: Remove un-named union from 'struct pollfd'. It is not - required by OpenGroup.org and violates the NuttX C coding standard - because it is not C89 compatible. From Gregory Nutt (2019-02-21). - * imxrt_adc: Error in offset From David Sidrane (2019-02-22). - * drivers/net/tun.c: Re-order all TUN/TAP driver state data. Not only - was was with wasting memory due to alignement requirements, it was also - causing network packet buffers to be improperly aligned causing - problems because the network requires 16-bit packet buffer alignment - for uint16_t accesses. This alignment problem was discovered by Alan - Carvalho de Assis. From Gregory Nutt (2019-02-24). - * drivers/net/tun.c: Packet buffer size should include the configured - GUARD_SIZE. And, given how the buffers are allocated, the allocation - size must be an even number of 16-bit values to preserve alignment. - From Gregory Nutt (2019-02-24). - * drivers/net/tun.c: Cosmetic changes from review for coding style - compliance. From Gregory Nutt (2019-02-24). - * SX127X improvements - - drivers/wireless/lpwan/sx127x/sx127x: Add TX power configuration - - drivers/wireless/lpwan/sx127x/sx127x: Discard RX packets with - unsupported length - - drivers/wireless/lpwan/sx127x/sx127x: Refactor some logic - - drivers/wireless/lpwan/Kconfig: Move some hardcoded sx127x - configuration to Kconfig - - drivers/wireless/lpwan/Kconfig: Remove EXPERIMENTAL flag - - configs/b-l072z-lrwan1/sx127x: Board-specific sx127x configuration - - configs/nucleo-f091rc/sx127x: Board-specific sx127x configuration - - configs/nucleo-l073rz/sx127x: Board-specific sx127x configuration - LORA and FSK look fine but there is something missing for OOK and - communication is not working yet. - From Mateusz Szafoni (2019-02-24). - * support for pthread_mutex_timedlock From Leif Jakob (2019-02-24). - * sched/pthread/pthread_mutexlock.c: Fix an error in last PR.

From David Sidrane (2019-02-25). - * libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for - pthread_mutex_timedlock() was added recently, however no new system - call was added for the API make is usable only in the FLAT build. With - a pthread_mutex_timedlock() system call, there is no reason for a - pthread_mutex_lock() system call since it is now nothing more than an - wrapper around pthread_mutex_timedlock(), passing NULL for the time - value.

From Gregory Nutt - (2019-03-07). - * configs/omnibusf4: Initial support for the OmnibusF4 family of flight - management units. "OmnibusF4" is not a product name per se, but rather - a design spec that many product vendors adhere to. The spec defines the - major components, and how those components are wired into the - microcontroller. Airbot is one such vendor, and they publish a - schematic here: http://bit.ly/obf4pro. Other software that supports - the OmnibusF4 family include Betaflight, iNAV, and many others. PX4 - recently added support as well, using their own, non-upstreamed, - bespoke port of NuttX. No code from those resources is included in this - port. From Bill Gatliff (2019-03-08). - * libs/libnx/nxfonts: Fix a memory leak in the font cache.

Otherwise, - garbage from previous display may still be present from preceding - NxWM window. - - graphics/nxterm: Back out most of the preceding NxTerm changes - related to window size. apps/examples/nxterm passed the complete - NxTK window size. Those changes were needed to make - aps/examples/nxterm work. But NxWM passes the the size of the NxTK - main sub-window. So I needed to back out the changes and then change - the applications so that they passed the same value (the size of the - NxTK sub-window). - From Gregory Nutt (2019-03-09). - * Initial OTG support for STM32H7 and some minor improvements - - arch/arm/src/stm32h7/stm32h7x3xx_rcc.c: add support for HSI48 clock - - configs/nucleo-f207zg: add support for USB and initialize CDCACM if - configured - - configs/nucleo-h743zi: add support for USB and initialize CDCACM if - configured - - drivers/usbdev/Kconfig: fix type for USBDEV_TRACE_INITIALIDSET - - configs/teensy-3.x/usbnsh/defconfig: update config according to - change in USBDEV_TRACE_INITIALIDSET - From Mateusz Szafoni (2019-03-10). - * arch/arm/src/imxrt/imxrt_clockconfig.c: If SDRAM is actived it was - only running at 40MHz.

From Levin Li (2019-03-12). - * binfmt/nxflat.c: Correct a double free debug assertion. This occurs - when groups are enabled: (1) once via binfmt_exit and unload_module, - and (2) once via sched_releasetcb(). this was corrected by adding - logic to free/unload the memory once and nullify the pointer so that - cannot be freed a second time. This commit resolves Bitbucket issue - #145. From Valmantas Palikša (2019-03-12). - * binfmt/nxflat.c: Update to last NxFLAT change: The logic must respect - the reference count before freeing the dspace memory region. From - Gregory Nutt (2019-03-12). - * tools/nxstyle.c: Don't complain about certain lowercase characters in - otherwise uppercase pre-processor identifers: IPv6, IPv4, ICMPv6, - IGMPv2, p as a decimal point, d signifying a divisor. It was a bad - idea to let the door open a crack for there. While they improve - readability, the inconsistently also causes other problems. From - Gregory Nutt (2019-03-12). - * arch/arm/src/nrf52: 1. added RNG device driver 2. added errdata to - correct temp which will be used by RNG module 3. use general - task_trigger / event_clear inline api for all driver.

The incorrect - method was generating errors as ARMv7-a expects the MCR/MRC - instructions to provide registers as an argument(MRC p15, 0, , c2, - c0, 0) and the code was providing a constant value(and hence the build - error). From Bilal Wasim (2019-03-14). - * This commit brings the per-framebuffer logic to code-complete. Still - untested. - - graphics/nxbe: The moverectangle renderer now supports updates to - the per-window framebuffer (unclipped) as well as the graphics device - memory (clipped). - - graphics/nxbe: The filltrapezond renderer now supports updates to - the per-window framebuffer (unclipped) as well as the graphics device - memory (clipped). - - graphics/nxbe: The getrectangle method now returns data from the - per-window framebuffer if available. - - graphics/nxbe: The fillrectangle renderer now supports updates to - the per-window framebuffer (unclipped) as well as the graphics device - memory (clipped). - - graphics/nxmu: If a window supports a per-window framebuffer, then - redraw callbacks are suppressed and the device content is updated - from the shadow, per-window framebuffer. graphics/nxbe: The - copyrectangle renderer now supports updates to the per-window - framebuffer (unclipped) as well as the graphics device memory - (clipped). - - graphics/nxbe/nxbe_setsize.c: Reallocate the per-window framebuffer - when the window size changes. - From Gregory Nutt (2019-03-15). - * configs/nucleo-f446re: Add support for the Nucleo F446RE.

However, that window must then then be in - window relative coordinates, not in absoute device coordinates. From - Gregory Nutt (2019-03-20). - * configs/lpcxpresso-lpc54628: Add a configuration for - apps/examples/pwlines. From Gregory Nutt (2019-03-20). - * configs/stm32f769i-disco/netnsh/defconfig: Remove - CONFIG_STM32F7_QUADSPI=y from the configuration. This was apparently - set before the implementation was added. Now that the implementation - was added, the configuration will not build because it requires that - QSPI GPIO pin definitions be provided in the board.h header file. - From Gregory Nutt (2019-03-20). - * arch/arm/src/stm32f7/stm32_qspi.c: Fix a warning about QSPI_DMA_PRIO - being redefined.

From Mateusz Szafoni (2019-03-24). - * arch/arm/src/stm32/stm32_pwm.c: Missing commas in initializers can - break compilation in certain configurations. From Mateusz Szafoni - (2019-03-24). - -7.30 2019-05-19 Gregory Nutt - - * arch/ and config/ files: All board interfaces (those starting with - board_) must be defined in board-specific logic. Otherwise, they cannot - be customized for specialized usage by different boards. The - board_reset() interface was defined in architecture-specific logic that - only called up_systemreset(). That is useless! This change removes the - board_reset() implementation from the architecture-specific code and - re-implements it in the src/ directory of each board that has - CONFIG_BOARDCTL_RESET enabled. That is the correct functional - partitioning. From Gregory Nutt (2019-03-25). - * configs/omnibusf4/src/stm32_reset: Add boardctl() reset logic. From - Bill Gatliff (2019-03-25). - * arch/arm/src/stm32f7/stm32_qspi.c: Fix QuadSPI interrupts. This commit - essentially replaces wrongly named configuration variables - STM32F7_QSPI_INTERRUPTS into CONFIG_STM32F7_QSPI_INTERRUPTS. Also fixes - some getreg/putreg where register addresses were used instead of - register offsets From Pierre-Olivier Vauboin (2019-03-25). - * graphics/nxmu, include/nuttx/nx/nxmu.h, libs/libnx: Add new - server->client callback to notify the window client of server events. - Remove the old 'blocked' callback and just make it one case of an 'event' - callback. From Gregory Nutt (2019-03-25). - * graphics/ and libs/libnx: Implement new interfaces nx_synch() and - nxtk_synch(). This are used to synchronize the NX server with the window - client. Currently most of the logic is equivalent to nx_block() and - nxtk_block(), but with slightly different semantics. They are separate - now because they are likely to diverge in the future. From Gregory Nutt - (2019-03-25). - * configs/stm32f103-minimum/src/: USB reset was not working appropriately - since the pin connected to D+ was incorrectly defined and the pullup/down - logic was reversed. From Matias N (2019-03-25). - * configs/omnibusf4: Add board_ioctl() which is needed only if - CONFIG_BOARDCTL_IOCTL=y is selected; Update NSH configuration to enable - board IOCTLs and DFU mode reset. From Bill Gatliff (2019-03-26). - * include/limits.h: Remove the duplicate TMP_MAX definitions. The - standard requires that TMP_MAX defines be in stdio.h. From Xiang Xiao - (2019-03-26). - * include/sys/select.h: Fix compiler error when CONFIG_NSOCKET_DESCRIPTORS - is undefined. From Xiang Xiao (2019-03-26). - * arch/arm/src/armv7-a/Toolchain.defs: Fix 'cc1: warning: switch - -mcpu=cortex-a7 conflicts with -march=armv7-a switch' From Xiang Xiao - (2019-03-26). - * drivers/usbdev/cdcacm.c: This fixes a problem where the host sent a "get - descriptor" message of type "standard" with a recipient of type - "interface". Since the composite driver would only pass messages to the - child interfaces when a message was not "standard", this message was not - handled. I changed the condition so that the composite driver checks not - only if this is a "standard" message but if it is also directed to the - device. Otherwise, the handling is delegated to the children of the - composite device. From Matias N (2019-03-26). - * drivers/video/max7456.c: Adds a read-only (for now) /dev/osd0/CM - interface for obtaining the chip's onboard NVM character map data. Use - seek() to position the cursor over a desired subset of bytes, or request - a large read to obtain the entire EEPROM memory contents. Values are - returned in binary form. Use hexdump, etc. to format them for viewing. - From Bill Gatliff (2019-03-26). - * configs/nucleo-l476rg/src/stm32_gpio.c, - configs/stm32f103-minimum/src/stm32_gpio.c, and - drivers/sensors/zerocross.c: Fix some errors when debug assertions are - enabled. From Matous Pokorny (2019-03-29). - * configs/boardctl.c, include/sys/boardctl.h: Add a command to start the - VNC server. From Gregory Nutt (2019-04-02). - * drivers/syslog/syslog_stream.c: In syslog buffered mode, avoid IOB alloc - lock-up with heavy network activity. This change alters the buffered - syslog logic to use 'iob_tryalloc' instead of blocking 'iob_alloc' to - avoid syslog printing from getting stuck when all IOBs are depleted by - network activity. An issue was seen when large incoming TCP transfer - uses free IOB buffers and processing threads try to use syslog which then - block at iob_alloc. From Jussi Kivilinna (2019-04-03). - * arch/stm32f7: Support bypassing the input clock divider on the SDMMC - interface. This enables using the full clock speed provided to the SDMMC - interface with no dividing.

From Anthony Merlino (2019-04-03). - * arch/arm/src/nrf52/nrf52832_errdata.c: Fix compiler error when following - C89. From Erik Englund (2019-04-03). - * PIC32MZ: The commit corrects the gpioirq when mismatch mode is selected - and add support for edge detect mode. Slew Rate was also added for - completeness. From Abdelatif Guettouche (2019-04-03). - * libs/libc/stdio/lib_libvsprintf.c: Restore support for printing NULL - string as "(null)". Legacy printf supported printing "(null)" in place - for NULL string: printf("null: %s\n", NULL); => null: (null). This - commit restores this functionality for new printf library. From Jussi - Kivilinna (2019-04-04). - * fs/littlefs/lfs.c: Fix lfs_format bug. In superblock disk root-block - assignment, the second must be root[1].

This bring the software cursor to code complete. Still - untested. From Gregory Nutt (2019-04-09). - * graphics/nxbe: Add some missing checks: Don't permit the software - cursor to be enabled until it has been assigned an image; don't perform - any cursor operations while the cursor is disabled. From Gregory Nutt - (2019-04-10). - * include/nuttx/usb/hid.h: The usbhid_descriptor_s struct defined in hid.h - included some optional fields that should not be hard-defined as part of - that structure. An arbitrary number of optional entries could be - included in the descriptor, but that is not properly represented. No - code on NuttX currently depends on the structure definition with an - optional descriptor so it is safe to remove. From Matias N (2019-03-30). - * arch/arm/src/stm32f7/stm32_otgdev.c: Correct hard-coded FIFO size that is - wrong for OTG FS.

Still at least one big bug - in the logic. From Gregory Nutt (2019-04-13). - * arch/arm/src/stm32: As noted by Matias N, the FLASH base address used - was incorrect. It was using the address of the FLASH data, not the - address of the FLASH registers. From Gregory Nutt (2019-04-13). - * arch/arm/src/stm32/stm32f10xxf30xx_flash.c: RCC register access should - not be offset by FLASH register base. From Matias N (2019-04-13). - * graphics/nxbe: This seems to fix the last of software cursor bugs. On - the LPC54, it looks pretty clean. Not flickery as I feared. Probably - not so good on low end displays. Possible transient artifacts? Not - sure, maybe. Or maybe my eyes are playing tricks from staring at this - too long. From Gregory Nutt (2019-04-13). - * configs/stm32f103-minimum/src: Add PROCFS automount support From Alan - Carvalho de Assis (2019-04-14). - * net/utils: net_lock() and net_restorelock() now return a value. That - values is the standard zero on success; negated errno value on failure. - This return value is only needed for -ECANCELED. That cancellation - indication needs to ripple all the way back to the highest levels where - the cancellation can be acted on. This commit only adds the return - value; it does not add checking for the return values of net_lock() and - net_restorelock() at higher levels. That is required too. From Gregory - Nutt (2019-04-14). - * configs/stm32ldiscovery/src: Add support for board_late_initialize(), - Move common initialization logic out of board_app_initialize() into new - file stm32_bringup.c From Gregory Nutt (2019-04-15). - * drivers/leds/userled: Fix ledset validity check in ULEDIOC_SETALL - ioctl.

This was - replaced with CONFIG_SERIAL_RXDMA and CONFIG_SERIAKL_TXDMA which will - permit supporting DMA on only one or both streams. From Gregory Nutt - (2019-04-24). - * configs/stm32f103-minimum/src/stm32_mcp2515.c: Patch up more breakage - found in build testing.

From Gregory Nutt (2019-04-24). - * arch/arm/src/stm32h7/stm32_start.c: Inclusion of nvic.h should not be - conditioned on CONFIG_ARCH_FPU. From Mateusz Szafoni (2019-04-25). - * arch/arm/src: Remove dependency on CONFIG_ARCH_FPU for inclusion of - nvic.h in all other *_start.c files.

From Phil Coval - (2019-04-25). - * configs/nucleo-h743zi/nsh/defconfig: Enable the FPU. From Jason Harris - (2019-04-25). - * Revert "sched/clock/clock_initialize.c: clock_inittime() needs to be - done with CONFIG_SCHED_TICKLESS and clock_initialize should skip - clock_inittime() for external RTC case since the RTC isn't ready yet." - This reverts commit 2bc709d4b99447f8decdc7580fdabab6dd8939b1. Commit - 2bc709d4b99447f8decdc7580fdabab6dd8939b1 was intended to handle the case - where up_timer_gettime may not start from zero case. However, this - change has the side-effect of breaking every implementation of tickless - mode: After this change the tickless timer structures are used before - they are initialized in clock_inittime(). Initialization happens later - when up_initialize is called() when arm_timer_initialize(). - - Since the tickless mode timer is very special, one solution might be to: - (1) Rename xxx_timer_initialize to up_timer_initialize, (2) Move - up_timer_initialize to include/nuttx/arch.h, and (3) Call it from clock - subsystem instead up_initialize. Basically, this change make timer - initialization almost same as rtc initialization(up_rtc_initialize). For - now, however, we just need to revert the change. From Gregory Nutt - (2019-04-26). - * nucleo-144: Mount sysfs for ifconfig for f767-netnsh/defconfig.

From Jukka Laitinen - (2019-04-30). - * arch/arm/src/stm32h7/chip/stm32h7x3xx_pinmap.h: Add the - GPIO_ETH_RMII_RXD1 pinmap definition for STM32H7. From Jukka Laitinen - (2019-04-30). - * arch/arm/src/stm32h7/stm32_i2c.c: Fix I2C4 compilation for STM32H7. From - Jukka Laitinen (2019-04-30). - * arch/arm/src/stm32h7/: Add stm32h7 Ethernet driver. This is the initial - push for the Ethernet driver. The driver has been tested to be working - on a nucleo board. This is still WIP, it doesn't for example do MAC - filtering on HW level, but just receives all ethernet packets. From - Jukka Laitinen (2019-04-30). - * arch/arm/src/stm32h7/: Add timer devices driver for STM32H7. This is - mostly a forklift from stm32f7 with some h7 specific modifications. From - Jukka Laitinen (2019-04-30). - * - Mostly arch/arm/src/imxrt and include/imxrt: This commit gets imx1020 - family support started. It is pretty similar, but subtly different, to - 1050/60 (less PLLs, less GPIO banks, differently numbered ports etc. - etc.). I think it's time to at least look at what needs to be done - before we can get these into the mainline kernel even though they're not - properly mature yet. Core memory functions, PLLs, serial and networking - are all working, but there's no stress-testing or similar been done...I'm - not aware of anything broken, but there again I haven't looked too hard. - - I want to go through and start moving each of the imxrt family-specific - files into its own subdirectory to tidy things up a bit, and remove the - vast majority of ifdefs from the mainline code...but I think it's - appropriate to separate the cleanup steps from the new-chip-support - steps to keep things a bit more compartmentalized. Next week is a travel - week so it's possible I'll get time on the cleanup side of the house. - - I can't be 100% certain I didn't inflict casualties on the imxrt1050/60 - code in the process of doing this, but nsh for 1050 and netnsh and nsh - for the 1060 both compile correctly, so if I did break anything it's - going to be properly evil and difficult to find. - - - Directory re-arrangement and splitting of each imxrt family variant - - Prevent intermittent SDCard timeouts by increasing timer in line with - spec. - - Support data dump on Hardfault - - Fix missing ccm definitions and wrong iomux offset - - Prevent hardfault when can't read from ENET PHY - - More consistent Ethernet pinmux. - From Dave Marples (2019-04-30). - * include/nuttx/usb/hid.h: The usbhid_descriptor_s struct defined in - hid.h included some optional fields that should not be hard-defined as - part of that structure. An arbitrary number of optional entries could be - included in the descriptor, but that is not properly represented. No - code on NuttX currently depends on the structure definition with an - optional descriptor so it is safe to remove. - * Documentation/NuttShell.html: Command date is misspelled as data in - chapter 2.12 Show or set the date and time (date). From Michał Łyszczek - (2019-05-01). - * configs/same70-xplained/twm4nx/defconfig: Increase packet MTU to 1500. - From Gregory Nutt (2019-05-03). - * Fix build for battery gauge From Tom Kopriva (2019-05-03). - * configs/same70-xplained/twm4nx/defconfig: Switch to 8BPP.

This features - is needed by Twm4Nx: When a window is iconified, the icon should appear - on the background and the window should disappear (i.e., be hidden). The - windows needs to remain healthy and to be updated in all ways, but it - cannot affect the display content. - - Conversely, when the icon is clicked, the icon needs to be hidden on - the background and the window needs to be restored in its current state - (which may be different than the state of the window at the time it - was iconified. - From Gregory Nutt (2019-05-05). - * arch/arm/src/stm32h7: Add missing parts for timer driver: Add the - missing header files, add the driver Kconfig, and add it to make - system. From Jukka Laitinen (2019-05-05). - * configs/nucleo-h743zi/include/board.h: Add the input clock frequency - definitions for all the drivers. Assumes internal clock source for all - the timers.

From Gregory Nutt (2019-05-06). - * graphics/: Windows can now be created in the hidden state. This can be - used to clean up initial window presentation which may involve several - steps. This makes those steps all invisible until nx[tk]_setvisibility() - is called to make the windows visible. From Gregory Nutt (2019-05-07). - * libs/libnx/nxtk/nxtk_events: Fix an error in handling mouse events for - framed windows. When drawing, NX may report mouse positions outside of - the Window. The is only for NX windows, but the outside-the-side - positions were being discarded by nxtk_events(). From Gregory Nutt - (2019-05-07). - * net/sixlowpan/sixlowpan_hc06.c: Correct an endian-ness problem in HC06 - decompression. From Ivan Ucherdzhiev (2019-05-08). - * arm/src/lpc54xx/: Bring in the USB FS OHCI driver from LPC17. This is a - quick'n'dirty port that I will finish sometime later (I hope). - Currently, it is missing hardware clocking setup and is not even hooked - into the build system yet. Needless to say it does not yet even - compile.

The abnormal termination handler must obey the rules of - cancellation points: If cancelation is disabled, then the abnormal - termination logic must wait for cancelation to be re-enabled; If - cancellation is deffered then the abnormal termination logic may have to - wait for the victim task to enter or exit a cancellation point. From - Gregory Nutt (2019-05-17). - * arch/arm/src/stm32f0l0: Add support for AES, RND, and HS148 for L0. - Move HSI48 enable from stm32_usbdev.c to stm32xx_rcc.c From Mateusz - Szafoni (2019-05-17). - -7.31 2019-07-21 Gregory Nutt - - * drivers/net/telnet.c: Handle ctrl events (SIGINT, SIGSTP).

From Gregory Nutt (2019-05-21). - * Documentation/: Applies a stylesheet to static HTML files. I've also - tried to put the TOC of each document to the side, where it made sense - (in some documents the TOC was actually inside a section so it wasn't - possible). In some cases the TOC is built with a table, in others with a -
    element, so I had to accommodate for this. I also didn't go into - collapsing, although this could really help for some long TOCs.

From Gregory Nutt (2019-05-22). - * graphics/nxbe/nxbe_raise.c: Fix a critical list handling bug in the - graphics system. When a lower-level window was raised while a model - window was in place, then list corruption could occur. From Gregory Nutt - (2019-05-23). - * Rename all arch//src//chip to - arch//src//hardware. This eliminates a name collision that - is usually harmless but does cause problems at the time. The problem is - because the include path includes '.' and 'chip/.', therefore an - inclusion like '#include /src//chip - and at arch//src/chip/chip From Gregory Nutt (2019-05-24). - * arch/mips/src: Previous commit used CP0 register definitions that were - not defined in the cp0.h header file. Probably these were from the - Microchip hacked up GCC toolchain but are not generally available. Fix: - Add definitions to NuttX cp0.h header file. From Gregory Nutt - (2019-05-25). - * mm/iob: Eliminate some warnings about testing the value of an undefined - pre-processor variable. From Gregory Nutt (2019-05-25). - * STM32F7 DTCM add procfs register From Daniel Agar (2019-05-25). - * fs/procfs/fs_procfs.c: procfs_initialize() is used only within - fs/procfs/fs_procfs.c and, hence, should be marked 'static'. From - Gregory Nutt (2019-05-25). - * configs/lpcxpresso-lpc54628: Modify the TWM configurations to properly - inject keyboard data. This way, in the case of multiple NxTERMs, only - the NxTerm at the top of the hierarchy gets the keyboard input. - Otherwise, it is not possible to use multiple NxTerms with each the - keyboard input going to a different NxTerm window. From Gregory Nutt - (2019-05-26). - * arch/arm/src/stm32f0: Initial support for STM32G0. From raiden00pl - (2019-05-27). - configs/: initial support for nucleo-g071rb. From raiden00pl (2019-05-27). - * Here's a patch to split the STM32 FMC/FSMC functionality (FSMC = flexible - static memory controller, FMC = flexible memory controller = FSMC + sdram - support). This commit makes FMC it's own thing rather than piggy backing - on the FSMC code. The peripherals have a few utility functions and this - commits lets you have a common function in the arch/arm/src/stm32 rather - than having duplicate functions in the board code. From Jason Harris - (2019-05-27). - * Rename STM32F0L0 to STM32F0L0G0 since it now also supports the STM32G0 - thanks to Mateusz Szafoni's contribution From Gregory Nutt (2019-05-27). - * arch/arm/src/stm32/stm32_fsmc.h: Fix the include file guarding name in - stm32/stm32_fsmc.h.

From - Gregory Nutt (2019-06-02). - * net/usrsock: Fix debug logs and remove DEBUGASSERT from - usrsockdev_do_request(). In a client mode, socket() will be the first - request for usrsockdev_do_request(). However, in a server mode, the - first request to accepted sockets will be recv() or others which depend - on applications. So I think we should remove this DEBUGASSERT from - usrsockdev_do_request(). From Masayuki Ishikawa (2019-06-03). - * arch/arm/src/STM32H7: Port PWM from STM32 From raiden00pl (2019-06-03). - * arch/arm/src/common/up_lwl_console.c: Add support for a 'Lightweight - Link' protocol between a target and debugger for use when you need a - console but the target doesn't have a spare serial port or other - available resource.

Currently these are not available if the - interface is part of a composite device, since only interface and - endpoint descriptors are copied by usbhost_copyinterface(). This commit - will also copy any class-specific interface descriptors for use in - downstream class drivers. NOTE: There's one change that might be - incorrect, where I skip interfaces with zero endpoints. I did this - because my device has two consecutive interface descriptors with the same - interface number, one for altsetting 0 with no endpoints, and another for - altsetting 1 with 1 endpoint.

In RX fifo - header, the first byte should use 5 lsb to store PKTLEN and 3 msb to - store PIPENO. However, FIFO_PIPENO_SHIFT was set to 4 which causes the - lsb of pipe number to interfere with the received packet size stored in - the fifo. This fix rx corruption when using pipe number > 0.

Enable - READLINE_CMD_HISTORY, enable by default SPI 4 and 5, and enable SPI to - keep all configurations in sync. From Alin Jerpelea (2019-07-01). - * net/inet: Fix tcp active close in inet_close.c. In previous - implementation, FIN packet was not sent when a socket is actively closed - (e.g. telnetd or webserver) without SO_LINGER. This issue happens - because the socket closing sequence waits for the status.cl_sem only if - lingering timeout is set. However, in many server use-cases, SO_LINGER is - not usually set and even in these cases, FIN packet must be sent - correctly. This changes the logic in inet_close.c so that it can wait - for status.cl_sem regardless of SO_LINGER. Instead, if SO_LINGERis set, - it waits for the semaphore with timeout option. From Masayuki Ishikawa - (2019-07-01). - * net/inet/inet_close.c: Last change removed SO_LINGER socket option - functionality. SO_LINGER was always enabled is CONFIG_NET_SOLINGER was - selected. This change implements a proper version of SO_LINGER. It is - based on new logic to drain the buffered TX data, integrated with network - event notification system. Supports notification when UDP or TCP write - buffer becomes empty. From Gregory Nutt (2019-07-01). - * configs/spresense: Add support for MSC and USB Composite device. Adds - usbmsc configuration.

From Masayuki Ishikawa (2019-07-06). - * arch/arm/src/am335x/hardware: Add register description files for I2C - (plus various improvements to the WDOG register definitions) From Petro - Karashchenko (2019-07-06). - * arch/arm/src/am335x/hardware: Add register description files for MCSPI. - From Petro Karashchenko (2019-07-06). - * Documentation/NuttXCCodingStandard.html: Another small change - discouraging the practice of enclosing the value argument of 'return' - statements in parentheses. From Gregory Nutt (2019-07-06). - * configus/nucleo-144: Add reset feature. Code is derives from - configs/stm32f4discovery/src/stm32_reset.c. It can be enabled using - CONFIG_BOARDCTL_RESET From Phil Coval (2019-07-07). - * video/edid/: Add some initial EDID logic ported from FreeBSD. From - Gregory Nutt (2019-07-07). - video/: Add basic configure and build support for a video subsystem. - From Gregory Nutt (2019-07-07). - * arch/arm/src/am335x/hardware/am335x_cm.h: Fix a typo in a macro name. - From Gregory Nutt (2019-07-07). - * arch/arm/src/imxrt: Implements USDHC1 & 2 selection on the imxrt. If - only one port is active (either 1 or 2) it will always be numbered as 0, - if both are active then USDHC1 will be number 0, USDHC2 will be 1. From - Dave Marples (2019-07-07). - * video/edid/edid_sort.c: Add logic to sort video modes by how close they - are to the preferred mode. This is part of the logic to pick the best - possible video mode. From Gregory Nutt (2019-07-07). - * tools/: Add spk binary format. The .spk binary format is used on - spresense and other boards based on the cxd56 arch. to enable this - binary format please set in your config CONFIG_CXD56_BINARY=y. From Alin - Jerpelea (2019-07-08). - * config/spresense: Build nuttx.spk images. Enable nuttx.spk binary image - that can be flashed on spresense board. From Alin Jerpelea (2019-07-08). - * configs/spresense: Add entry point for mpy. The entry point is needed - for the downstream projects based on spresense. From Alin Jerpelea - (2019-07-08). - * configs/nucleo-h743zi/src/stm32_spi.c: Correct typos in function - naming. From Jonathan Richner (2019-07-08). - * arch/arm/src/am335x/hardware/am335x_lcd.h: Fix a few typos. Add things - needed by the LCDC driver. From Gregory Nutt (2019-07-08). - * This change brings in an initial LCD driver sof the AM335x architecture. - This is a work in progress and so depends on EXPERIMENTAL. The code is - nearly compete, missing some clock configuration settings. It does yet - even compile properly. From Gregory Nutt (2019-07-08). - * arch/arm/src/am335x: Add logic to map the framebuffer to a non-cached, - non-buffered memory region. From Gregory Nutt (2019-07-08). - arch/arm/src/am335x: Remove struct am335x_fbinfo_s. Replaced with - configuration settings that provide the same information. From Gregory - Nutt (2019-07-08). - * arch/arm/src/am335x/am335x_sysclk.c: Add a function to return a - frequency of the system clock. From Gregory Nutt (2019-07-08). - * arch/arm/src/am335x/am335x_lcdc.c: Add logic to get/set the module - reference clock. Still one more clocking interface to do. From Gregory - Nutt (2019-07-08). - * configs/beaglebone-black/lcd/defconfig: Add a configuration for bringing - up the LCDC driver. From Gregory Nutt (2019-07-08). - * tools/: Add flash_writer for cxd56 boards. This flash writter is using - the xmodem for firmware transfer for flashing please use: - 'tools/flash_writer.py -s -c /dev/ttyUSB0 -d -b 115200 -n nuttx.spk' - From Alin Jerpelea (2019-07-09). - * Update COPYING file. Tools in the tools/ directory are not intended for - binary redistribution and may not all conform to BSD licensing. From - Gregory Nutt (2019-07-09). - * On the LPC1769 there are two 16 KiB AHB SRAM blocks, which are mapped - back to back at physical address 0x2007C000 and 0x20080000 (i.e. right - below and right above a 512 KiB boundary). Memory from those two blocks - is considered continuous when assigned to a heap. In the protected build - mode, when the memory protection unit is used, though, it must be split - into two MPU regions. This is because MPU regions must be naturally - aligned, and the 32KiB continuous address space of the two 16KiB AHB SRAM - blocks does not start at an address divisible by 32KiB. The only other - configurations that use protected build mode on lpc17xx are currently - open1788/knsh and open1788/knxterm. The LPC1788 has the AHB SRAM blocks - mapped more sanely (from an MPU region point of view), which is probably - why no problems emerged here. Both still compile with my change and - other than wasting an MPU region (which would otherwise remain unused) - should work fine. That said, I have no hardware to confirm. From - Michael Jung (2019-07-09). - * configs/pnev5180b/knsh: Add PROTECTED mode configuration with - NuttShell. From Michael Jung (2019-07-09). - * configs/beaglebone-black/src/am335x_lcd.c: Framework (only) for TDA19988 - and LCD support for Beaglebone Black. Can't use TDA19988 yet because - there is no I2C driver. In the mean time, support LCD initialization - using a fixed, configurable video mode. From Gregory Nutt (2019-07-09). - * arch/arm/src/am335x/hardware/am335x_prcm.h: Rename am335x_cm.h to - am335x_cm.h. From Petro Karashchenko (2019-07-09). - * arch/arm/src/am335x: Changes related to Control Module From Petro - Karashchenko (2019-07-09). - * arch/arm/src/am335x/Kconfig: Remove unused configuration settings left - over from original copy-paste.

From uan Flores (2019-07-10). - * drivers/sensors/vl53l1x.c: Added support for VL53L1X TOF sensor. From - Juan Flores (2019-07-10). - * drivers/lcd/tda19988.c: Now uses the new common videomode structure of - include/nuttx/video/videomode.h as do other video components. From - Gregory Nutt (2019-07-10). - * video/, include/nuttx/video/videomode.h: Separate EDID and from - videomode management. They really are separate things. From Gregory - Nutt (2019-07-10). - * video/edid: Add debug functions to dump the EDID and videomode content. - From Gregory Nutt (2019-07-10). - * viedo/videomode: Rename video/edid to video/videomode. There is more - there than just EDID but it is all basically videomode stuff. From - Gregory Nutt (2019-07-10). - * video/videomode/vesagtf.c: Bring VESA Generalized Timing Formula (GTF) - from FreeBSD. From Gregory Nutt (2019-07-10). - * video/videomode/videomode_lookup.c: At some additional lookups from - FreeBSD. Not currently used in NuttX so ifdef'ed out for now. From - Gregory Nutt (2019-07-10). - * configs/spresense: Enable internal flash storage for spresense boards. - The smartfs flash is mounted under /mnt/spif folder. From Alin Jerpelea - (2019-07-11). - * configs/spresense: For compatibility with SDK we need to change the - USER_ENTRYPOINT in all configurations to spresense_main(). From Alin - Jerpelea (2019-07-11). - * include/cxx/cstddef: Add C11++ std::nullptr_t From junmin-kim - (2019-07-11). - * configs/olimex-stm32-e407: Added BMP180 initialization and a - configuration to test the BMP180. From Juan Flores (2019-07-11). - * include/nuttx/spi/spi.h: Added standard definitions for ADC SPI device - ID. From Daniel P. Carvalho (2019-07-11). - * arch/arm/src/lpc17xx_40xx and configs/: Add support for LPC40xx family - chips. Renamed LPC17XX to LPC17XX_40XX in directory, configuration, file - names, etc., as appropriate. Corrected a few peripheral definitions and - pin functions for the LPC17xx family. Added configuration options, chip - definitions, and additional pin functions for the LPC40xx family. - configs/lpc4088-devkit/: Added board configuration for Embedded Artists - LPC4088 Developer's kit. From jjlange (2019-07-11). - configs/lpc4088-devkit/: Added board configurations for Embedded Artists - LPC4088 Quickstart board. From jjlange (2019-07-11). - * include/fixedmath.h: Regarding the single precision float to/from fixed - point conversions in fixedmath.h, I believe the floating point literals - should be appended with the letter 'f' to avoid (expensive) conversions - from single to double precision, and thereby also avoid (expensive if - done in SW) double point arithmetic (which is what is happening upon - inspection of my disassembly). From rajan gill (2019-07-11). - * arch/arm/src/lpc11xx, arch/arm/include/lpc11xx, - configs/lpcxpresso-lpc1115: Support for the LPCXpresso-LPC1115 and for - the LPC1115 architecture in general was removed after NuttX-7.30. The - LPC11 port was never really used (to my knowledge) and was no longer - supported. A snapshot of the port is still available in the Obsoleted - repository. It can be brought back into the main repository at any time - if anyone is willing to provide support for the architecture. From - Gregory Nutt (2019-07-11). - * configs/spresense: Fix and refactor cxd56_leds.c From Masayuki Ishikawa - (2019-07-12). - * arch/arm/src/cxd56xx: Add GNSS device, add Geofence Support, add UART0 - interface. UART0 is an interface with hardware flow control in the - application subsystem. From Alin Jerpelea (2019-07-12). - * configs/spresense: path correction. From Alin Jerpelea (2019-07-12). - * configs/olimex-stm32-e407: Add DAC support, add IN219 support, add timer - driver support.

From Alan Carvalho de Assis (2019-07-13). - * include/sys/syscall.h: Fixed SYS_mount syscall define when - CONFIG_FS_READABLE is undefined. From Joao Matos (2019-07-13). - * configs/stm32f769i-disco/src/stm32_pwm.c: Enable PWM support for - stm32f769i-disco board. From Gregory Nutt (2019-07-13). - * arch/arm/src/imxrt: Fix compiler error for CONFIG_IMXRT_USDHC1 && - !CONFIG_IMXRT_USDHC2 From David Sidrane (2019-07-13). - * arch/arm/src/STM32H7/stm32_ethernet.c: Fix typo in define. From - Pierre-Olivier Vauboin (2019-07-16). - * tools/flash_writer: license change. license update for project - compliance From Alin Jerpelea (2019-07-17). - * configs/stm32ldiscovery/: Add button support for stm32Ldiscovery. Add - chronometer board config. From Alan Carvalho de Assis (2019-07-17). - * configs/olimex-stm32-e407: Add support for MRF24J40 radio. From Gregory - Nutt (2019-07-18). - * configs/makerlisp/src/ez80_boot.c: The VGA display controller and - keyboard controller come up by default emulating a terminal with 'newline - mode' on. That is newlines expance to carriage-return, newline. This - patch turns that mode off. From Gregory Nutt (2019-07-20). - * configs/tm4c1294-launchpad/tools/oocd.sh: Fix syntax error. From Nathan - Hartman (2019-07-20). - * sched/sched/sched_waitpid.c: In waitpid, remember to grab the exited - child ptr. After being unblocked in waitpid, the child pointer might be - NULL. Modify to use group_exitchild to get the pointer of recent exited - child. From Yang ChungFan (2019-07-20). - -8.1 2019-09-14 Gregory Nutt - - * arch/arm/src/sam34/Kconfig: Add missing DMA configuration setting. - From Bernd Walter (2019-07-21). - * arch/mips/src/pic32mz/pic32mz-spi.c: Fix SPI Mode selection. CKE is - the inversion of the CPHA. From Ouss4 (2019-07-21). - * drivers/mtd/sst26.c: Accept the 16MBit Flash when reading the JEDEC-ID - at init. From Ouss4 (2019-07-21). - * arch/mips/src/pic32mz/pic32mz-config.h: Make the PLL input clock - configurable. From Ouss4 (2019-07-21). - * STM32F7: Fixes bad preprocessor logic preventing USB OTG HS to work - when used without external ULPI. From Anthony Merlino (2019-07-22). - * arch/arm/src/imxrt/imxrt_lpi2c.c: Slave addresses are now correctly - shifted when sending start. TX/RX FIFOs now discarded on error to - prevent FIFO underflow errors. Fixes error checking to use priv - structure and removes checking of BBF flag as it is not an error. From - Nicholas Chin (2019-07-23). - * configs/nucleo-l432kc/src/stm32_gpio.c: Added GPIO drivers for use - with /apps/examples/gpio. From Daniel P. Carvalho (2019-07-23). - * configs/nucleo-l432kc: Added Zero Cross sensor to nucleo-l432kc. From - Daniel P. Carvalho (2019-07-23). - * drivers/usbdev/rndis: Fixes issue with DEBUGASSERT when using composite - device and endpoint numbers not being the default. From Anthony - Merlino (2019-07-23). - * libs/libc/stdio/lib_libvsprintf.c: Add support for the size_t integer - qualifier 'z'. This is kind of tricky due the variety of - sizeof(size_t) on different platforms. From David Sidrane (2019-07-24). - * gs2200m with udp - - include/nuttx/wireless: Add udp support to gs2200m.h - - drivers/wireless: Add WL_GS2200M_DISABLE_DHCPC to Kconfig - - drivers/wireless: Add udp support to gs2200m.c - - configs/spresense/wifi: Enable smartfs and udp support - From Masayuki Ishikawa (2019-07-25). - * arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Abort I2C transfers if a - timeout has occurred. If a timeout has occurred in the middle of a I2C - transfer, the next I2C interrupt should abort any transfers and send a - stop condition to the corresponding I2C bus. Failure to do so will result - in memory corruption / undefined behavior as priv->msgs points to a - region of memory it doesn't owns anymore after lpc17_40_i2c_start - returns. From Augusto Fraga Giachero (2019-07-25). - * configs/tm4c1294-launchpad/src/tm4c_bringup.c: Enables /dev/userleds - for tm4c1294-launchpad by calling userled_lower_initialize() in - tm4c_bringup(). From Nathan Hartman (2019-07-25). - * arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Calculate the appropriate - timeout for I2C transfers. Depending on the bus frequency and transfer - size, I2C transactions can take quite a bit, so a fixed timeout is not a - good solution. Calculating the timeout at run time poses some overhead - but still better than aborting long transactions. From Augusto Fraga - Giachero (2019-07-25). - * net/udp: Remove net stack dependency from CONFIG_NET_BROADCAST. This - change allows us to use CONFIG_NET_BROADCAST without network stack. (i.e. - usrsock application can use broadcast) From Masayuki Ishikawa - (2019-07-26). - * STM32F7: If there is only one SDMMC it is slot 0 From David Sidrane - (2019-07-26). - * drivers/mtd/mx25rxx.c: add support for 512B sectors - - Fix for mx25rxx driver as it does not work properly - - Add mx25rxx memory chip and smartfs support in b-l475e-iot01a/nsh - config - - Update smartfs smart_scan() function From Simon Piriou (2019-07-26). - * configs/nucleo-l432kc: ADC: Change analog pins definitions and - correct DMA related issue. From Daniel P. Carvalho (2019-07-27). - * net/tcp and udp: Fix errors in the new implementation of SO_LINGER. - The tcp_drain() and udp_drain() functions were casting the working - argument to the wrong type, resulting in hangs and abnormal behavior. - There is a complexity in the tcp drain logic when the remote peer - closes the socket before all Tx data has been flushed. Sometimes we - are not notified of this case and wait the entire timeout - unnecessarily. There is a workaround in place in tcp_txdrain(), but - this really should be revisited. From Gregory Nutt (2019-07-27). - * arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Set speed back to - 10Mbps if 10Mmbps link negotiated. From Augusto Fraga Giachero - (2019-07-27). - * i.MXRT USDHC: This change completes SDIO support for IMXRT, and also - adds support for WiFi using the AP6212A module based on Simon Piriou's - rather excellent work. The patch should also address DavidS's concern - about width setting for USDHC1 and 2. Testing of the WiFi is minimal - so far but functionality is proven. I'm specifically not happy that - the driver doesn't recover elegantly from a DMA data checksum failure, - but that is an issue that can be dealt with in due course ... I'm - trying to get the rest of the interfaces fleshed out and the hardware - proven so it can go for pre-production build. I _think_ there's only - Bluetooth and USB-device left to implement now. From Dave Marples - (2019-07-28). - * arch/arm/src/imxrt/imxrt_clockconfig.c: Enable TRACE clocks if the - divider has been defined in the board's board.h file. From Dave - Marples (2019-07-28). - * net/udp/udp_txdrain.c: Add missing header file. From David S. Alessio - (2019-07-29). - * sched/semaphore/sem_holder.c: Fix a race in telnet with - PRIORITY_INHERITANCE and SCHED_HPWORK. Sometimes causes an assertion - to fire incorrectly. From David S. Alessio (2019-07-29). - * include/netinet/in.h: Rename __pad member to sin_zero in struct - sockaddr_in. Libwebsockets initializes the 'sin_zero' member of - sockaddr_in objects to zeros. Apparently, judging from mailing list - entries, there are platforms on which not doing this causes undefined - behavior. On NuttX compiling respective code is broken, as the - corresponding member variable is called '__pad'. Neither in the - 'nuttx' nor in the 'apps' repository did I find any reference to this - identifier. Thus, I believe its a safe bet to just rename it. UNIX - Network Programming states in this regard: "The POSIX specification - requires only three members in the structure: sin_family, sin_addr, and - sin_port. It is acceptable for a POSIX-compliant implementation to - define additional structure members, and this is normal for an Internet - socket address structure. Almost all implementations add the sin_zero - member so that all socket address structures are at least 16 bytes in - size." From Michael Jung (2019-07-29). - * arch/arm/src/tiva: Rename TM4C123GH6PMI identifiers to TM4C123GH6PM. - Rationale: In terms of firmware programming, there is no functional - difference between these parts: TM4C123GH6PMI7, TM4C123GH6PMI7R, - TM4C123GH6PMT7, and TM4C123GH6PMT7R. From a programming standpoint, - all of the above parts are TM4C123GH6PM, which means it doesn't make - sense to differentiate between PM and PMI. (The PM means 64-LQFP. The I - means temperature range -40C to +85C. It could be T meaning -40C to - +105C. The R means it ships in Tape and Reel packaging as opposed to - Tray.) From Nathan Hartman (2019-07-29). - * Only use PCLKSEL0 for ADC on LPC176x family. From jjlange (2019-07-29). - * arch/arm/src/tiva: Rename TM4C1294NC identifiers to TM4C1294NCPDT. - Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP, - TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently supported - by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL "Connected - LaunchPad" (see configs/tm4c1294-launchpad). To ensure the correct - part is fully specified, this commit updates all TM4C1294NC identifiers - to TM4C1294NCPDT. From Nathan Hartman (2019-07-29). - * libs/libc/machine/arm/armv7-m: Add Cortex M4F mach optimized fabsf and - sqrtf. From David S. Alessio (2019-07-29). - * gs2200m with dhcp: - - include/nuttx/wireless: Add GS2200M_IOC_IFREQ to gs2200m.h - - drivers/wireless: Add GS2200M_IOC_IFREQ to gs2200m.c - - configs/spresense/wifi: Enable NuttX's DHCP client instead of GS2200M's - - configs/spresense: Add descriptions on wifi in README.txt - From Masayuki Ishikawa (2019-07-30). - * libs/libc/machine/arm/armv7-m: Fix build error for elf From Masayuki - Ishikawa (2019-07-30). - * Documenation/, configs/: Fix typos and one HTML syntax error. Fix - HTML syntax error in Documentation/NfsHowto.html: -> - html tag. From Nathan Hartman (2019-07-30). - * fs/dirent/fs_opendir.c: Fix typo and style. opendir() did set errno - to a negative value in one error case. Fixed some coding style issues - found by nxstyle. From Michael Jung (2019-07-31). - * libs/libc/dirent/: Added alphasort() implementation, scandir() - implementation and DT_* definitions to include/dirent.h. Apparently - those definitions are not required by POSIX, but are part of 4.3BSD and - available in glibc as well. From Michael Jung (2019-07-31). - * libs/libc/dirent/lib_scandir.c: Do not build in PROTECTED or KERNEL - mode builds. Add FAR to some pointers. Minor comment updates. From - Gregory Nutt (2019-07-31). - * STM32F7: Serial add HW HS on UART 4 & 5 From David Sidrane - (2019-08-01). - * sched/task/task_exithook.c: nxtask_signalparent() in task_exithook.c - may invalidate the group's parent task ID (tg_ppid) too soon. The - tg_ppid field is use only to remember the parent tasks ID so that it - can send the SIGCHLD signal to it. So it must stay valid until SIGCHLD - has been sent. In nxtask_signalparent(), it calls nxtask_sigchild() to - send SIGCHLD to the parent, then invalidates tg_ppid. That would be - okay, except that the SIGCHLD is only sent when the last member of the - group terminates. That is incorrect; tg_ppid can be invalidated too - soon and, as a consequence, SIGCHLD would never be sent. Noted by - Jeongchan Kim in the Google group: - https://groups.google.com/forum/#!topic/nuttx/SXd8fVwVKBk From Gregory - Nutt (2019-08-01). - * confgs/z80sim/src/z80_serial.c: Fix uart_dev_t initializer: pollfds - is a array of pointers and, hence, the NULL initializer must be - included in braces. Noted by Paul Osmialowski in Issue #160. From - Gregory Nutt (2019-08-01). - * z80sim/src/z80_irq.c: Missed a name change - up_irqinitialize->z80_irq_initialize.

The NuttX task groups have been using - the acronym 'gid' and also the type 'gid_t' for the the task group ID. - That is incorrect. Than naming is reserved for use with group - permissions. So these were all named to grpid and grpid_t so that it - is clearer that these refer to NuttX task group IDs, and not to group - permissions. From Gregory Nutt (2019-08-02). - * arch/arm/src/tiva, include/nuttx/sensors: Reinstate TM4C qencoder - driver and expand its ioctls. - arch/arm/src/tiva/Kconfig: - - Add TIVA_HAVE_QEI0, TIVA_HAVE_QEI1 as applicable to each - ARCH_CHIP_TM4C12*. - - Add config TIVA_QEI, TIVA_HAVE_QEI0, TIVA_HAVE_QEI1. - - Add config TIVA_QEI0, config TIVA_QEI1. - arch/arm/src/tiva/common/tiva_qencoder.c: - - Rewrite tiva_qe_setup(). - - Replace tiva_qe_ppr() with tiva_qe_resetatppr(). - - Add tiva_qe_resetatmaxpos(), tiva_qe_resetatindex(). - arch/arm/src/tiva/hardware/tiva_qencoder.h: - - Add missing definitions: SIGMODE_QUADRATURE, SIGMODE_CLK_AND_DIR, - SWAP_NO_SWAP, SWAP_PHA_PHB. - arch/arm/src/tiva/tiva_qencoder.h: - - Rename TIVA QEI ioctl QEIOC_PPR to QEIOC_RESETATPPR. - - Add TIVA QEI ioctl identifiers QEIOC_RESETATMAXPOS, QEIOC_RESETATINDEX. - include/nuttx/sensors/qencoder.h: - - Increase QE_TIVA_NCMDS from 3 to 5. From Nathan Hartman (2019-08-02). - * libs/libc/grp: Added stubbed implementations of getgrgid, getgrgid_r, - getgrnam, getgrnam_r, and initgroups. These functions are essentially - stubs pretending that NuttX supported groups and that the only - configured group in the system was 'root' with gid 0. The intend is - not to provide meaningful new features, but to ease porting of foreign - source code to NuttX. From Michael Jung (2019-08-03). - * libs/libc/grp/lib_grp.c: Fix a warning when compiling on a 64-bit - simulation. Cannot cast a pointer to unsigned in that case because - unsigned (int) is only 32-bits, but the pointer is 64-bits. From - Gregory Nutt (2019-08-03). - * configs/sim/include/etc.tar.gz, nsh_romfsimg.h: Improve the format of - the /etc/passwd format. It is now a little more similar to other - systems. Add an /etc/group file to support future testing. From - Gregory Nutt (2019-08-03). - * libc/pwd: Added stubbed implementations. Added stubbed implementations - of getpwuid, getpwuid_r, getpwnam, and getpwnam_r. These functions are - essentially stubs pretending that NuttX supported users and that the - only configured user in the system was 'root' with uid 0. The intend - is not to provide meaningful new features, but to ease porting of - foreign source code to NuttX. From Michael Jung (2019-08-04). - * Rename the arch/risc-v/src/gap8/gap.h to arch/risc-v/src/gap8/gap8.h - From Kejun ZHOU (2019-08-04). - * libs/libc/pwd and libs/libc/grp: Modify to get user/group data from - /etc/passwd and /etc/group if so configured. - libs/libc/pwd/lib_find_pwdfile.c: Add logic to look up user - information in /etc/passwd file, if available. - libs/libc/grp/lib_find_grpfile.c: Add logic to look up group - information in /etc/group file, if available. - From Gregory Nutt (2019-08-04). - * arch/arm/src/tiva: LM3S, LM4F, TM4C: Fix GPIO IRQ error, ports R, S, - T. Preprocessor logic for CONFIG_TIVA_GPIOx_IRQS was setting/clearing - port Q defines when it should act on ports R, S, T. gpioport2irq() was - missing handling for port T. From Nathan Hartman (2019-08-04). - * Move board-related files to new boards/ folder. This effectively - renames the configs/ directory to boards/. This is the first step in a - much larger effort. This is the proposed layout after all of the change: - - boards/: - folder containing board folders - : - name of each board - drivers/: - extra drivers specific for platform - include/: - header files for the boars - scripts/: - extra scripts specific for platform - src/: - board specific code - tools/: - extra tools specific for platform - configs/: - board specific configuration(s) - - Replaced configs/ with boards/ in: Kconfig, Makefile, tools/Makefile.*, - all Make.defs, tools/*.sh, tools/*.bat, tools/*.mk, .c and .h files - under boards/ From Alin Jerpelea (2019-08-05). - * Change naming configs/ to boards/ in comments, Documentation, etc. - From Gregory Nutt (2019-08-05). - * net/udp/udp_psock_sendto_buffered.c: Fixes a copy-paste error in the - new SO_LINGER code: CONFIG_TCP_NOTIFIER to CONFIG_UDP_NOTIFIER.

From Gregory Nutt (2019-08-05). - * kinetis: i2c transfer ensure correct result returned. - kinetis_i2c_transfer released the mutex then fetched the state, this - resulted in returning the correct results. From David Sidrane - (2019-08-05). - * tools/configure.sh and .c: When dumping available configurations, omit - the 'config/' in the path. From Gregory Nutt (2019-08-05). - * tools/: Change preferred argument of configurations tools to use ':' - as the delimiter between and . This is to - emphasize that this is not a path; it is configuration specification. - The legacy '/' delimiter is still supported but not recommend and not - advertised. Updated configurations instructions in README.txt files to - show ':' delimiter vs '/' delimiter. Update all configuration-related - tools to accept ':' separator between board and configuration name. - From Gregory Nutt (2019-08-05). - * sched/mqueue/mq_desclose.c: Add a test to verify that message queue is - closed by the same task group that opened it. If not, then list - corruption would result. This test is only performed if - CONFIG_DEBUG_FEATURES is enabled since it should not normally be an - issue: It would be a strange programming practice to open a message - queue in open task group, then close it in another. From 김정찬 - (2019-08-05). - * libs/libc/unistd: Stubs for setuid and setgid. Added stubbed - implementations of setuid and setgid. These functions are essentially - stubs pretending that NuttX supported users and groups and that the - only configured user and group in the system were both 'root' with a - uid and a gid of 0, respectively. The intent is not to provide - meaningful new features, but to ease porting of foreign source code to - NuttX. From Michael Jung (2019-08-06). - * drivers/pipes: Use inode reference counter instead of device reference - counter to handle dup(). I found that if I dup() a pipe, the reference - counter d_refs is not increased. If I close any of the fd, backed by - the same pipe, the pipe will be freed. This causes any further usage - on the fd referencing a non existent pipe. This change uses the inode - reference counter, which is properly maintained during dup(). From - Yang ChungFan (2019-08-06). - * arch/arm/src/stm32h7: Fix UART7/8 typos. Fix bug in ETH_MACQTXFCR - configuration.

For - some reason this config wasn't referenced anywhere else except in - arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c. From Augusto Fraga - Giachero (2019-08-07). - * arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Follow the procedure - listed in the LPC176x/5x User Manual when reading from and writing to - the PHY's registers (section 10.11.14). I couldn't see any behavioral - change after this commit, but nonetheless is a good practice to follow - the manufacturer's recommended procedure. From Augusto Fraga Giachero - (2019-08-07). - * arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Fix the initialization - for DP83848x PHYs. The DP83848x requires the RMII mode to be manually - enabled through the MII_DP83848C_RBR register. Before querying the - speed and mode it should wait for the link to be established. From - Augusto Fraga Giachero (2019-08-07). - * Group boards based on chip. All boards based on the same chip are - moved to the same folder. For example, all STM32 configurations moved - from boards/arm/board to boards/arm/stm32/board. From Alin Jerpelea - (2019-08-07). - * Add defconfig files must include CONFIG_ARCH_CHIP= to break and - chicken-and-egg problem. From Gregory Nutt (2019-08-07). - * arch/sim: Even though the simulation has no "chips", it needs to have - CONFIG_ARCH_CHIP and chip sub-directories. Otherwise, we would have to - treat it as a special case in the build system. From Gregory Nutt - (2019-08-07). - * tools/: Update and verify all configuration related tools with new, - boards directory layout. From Gregory Nutt (2019-08-07). - * defconfigs: All paths assigned to CONFIG_PASS1_BUILDIR must include - the chip name. From Gregory Nutt (2019-08-07). - * arch/arm/src/tiva/common/tiva_timerlib.c: Fix one code error and some - comment errors. tiva_timer16_setinterval(): Was DEBUGASSERTing on mode - != TIMER16_MODE. Fixed to DEBUGASSERT on mode == TIMER16_MODE. From - Nathan Hartman (2019-08-07). - * boards/Board.mk: Correct a simulator inclusion path problem introduced - by reorganization of arch/sim/src. From Gregory Nutt (2019-08-08). - * drivers/sensors/sht3x.c: Add Sensirion SHT3x driver. From Markus - Bernet (2019-08-08). - * Beginning to update comments to reflect new organization of the boards/ - sub-directory.

From Alin Jerpelea (2019-08-08). - * Update more comments and README.txt files to reflect new organization - of the boards/ sub-directory. From Gregory Nutt (2019-08-08). - * Documentation: Update some documents affected by the change in the - organization of the boards/ sub-directory. From Gregory Nutt - (2019-08-08). - * boards/arm/lpc17xx_40xx/u-blox-c027/configs/nsh/defconfig: Remove - stray character in defconfig file.

From Gregory Nutt (2019-08-08). - * README.txt: Update for new boards/ sub-directory layout. From Gregory - Nutt (2019-08-08). - * arch/arm/include/armv7-m/nvicpri.h: In the 'normal' case, the priority - of the SVCALL interrupt was the same as the priority of the high - priority interrupt. This means that SVCALL interrupt processing can - defer the high priority interrupt and result in the jitter in that - interrupt response. Fix is to raise the priority of the high priority - interrupt above the priority of the SVCALL interrupt. Suggested by - Nathan Hartman. From Gregory Nutt (2019-08-09). - * After restructuring the boards/ directory, it is time for code style - cleanup: misoc, or1k, renesas, risc-v, sim, x86, xtensa, z16, z80 From - Alin Jerpelea (2019-08-09). - * Documentation/NuttX.html: Adjust URLs to board README.txt files to - account for changes in boards/ sub-directory reorganization. From - Gregory Nutt (2019-08-09). - * This commit removes CONFIG_ARCH_INT_DISABLEALL. In the normal course - of things, interrupts must occasionally be disabled using the - up_irq_save() inline function to prevent contention in use of resources - that may be shared between interrupt level and non-interrupt level - logic. Now the question arises, if we are using BASEPRI to disable - interrupts and have high priority interrupts enabled - (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except - SVCall (we cannot disable SVCall interrupts). Or do we only disable - the "normal" interrupts? If we are using the BASEPRI register to - disable interrupts, then the answer is that we must disable ONLY the - "normal interrupts". That is because we cannot disable SVCALL - interrupts and we cannot permit SVCAll interrupts running at a higher - priority than the high priority interrupts (otherwise, they will - introduce jitter in the high priority interrupt response time.) Hence, - if you need to disable the high priority interrupt, you will have to - disable the interrupt either at the peripheral that generates the - interrupt or at the NVIC. Disabling global interrupts via the BASEPRI - register cannot effect high priority interrupts. From Gregory Nutt - (2019-08-09). - * Tiva GPTM timers: Implement 16-bit PWM mode - arch/arm/src/tiva/Kconfig: - - Remove EXPERIMENTAL dependency on TIVA_TIMER16_PWM. - arch/arm/src/tiva/common/tiva_timerlib.c: - - Fix wrong 32/16-bit ifdef checks. - - Add tiva_pwm16_sel_event() to choose GPTMCTL.TnEVENT value. - - Implement tiva_pwm_mode16(). - - tiva_timer16_setinterval(): Fix wrong check for TIMER16_MODE_ONESHOT - and TIMER16_MODE_PERIODIC. Was comparing to config->cmn.mode which - can never have those values. This prevented interrupts being enabled. - Compare to timer->mode instead. - - Add tiva_timer16pwm_setperiodduty() to set initial period, duty - cycle, and enable interrupts if requested in GPTM peripheral. - Interrupts are not enabled in NVIC until tiva_timer16_start() is called. - - Add tiva_timer16pwm_setduty() to update duty cycle at any time. - arch/arm/src/tiva/hardware/lm/lm3s_timer.h, - arch/arm/src/tiva/hardware/lm/lm4f_timer.h, - arch/arm/src/tiva/hardware/tm4c/tm4c123_timer.h, - arch/arm/src/tiva/hardware/tm4c/tm4c129_timer.h: - - Add missing defines; make surrounding defines consistent. - arch/arm/src/tiva/tiva_timer.h: - - Add new TIMER_FLAG_* configuration flags to enable configuring - the16-bit PWM feature. Extend type of "flags" in tiva_timer32config_s - and tiva_timer16config_s from 8- to 32-bits to allow more flags. - From Nathan Hartman (2019-08-09). - * boards/arm/efm32/olimex-efm32g880f128-stk/src/.gitignore: Restore - .gitignore file that was lost in the boards/ directory reorganization. - From Nathan Hartman (2019-08-09). - * STM32F7: USART1_RXDMA is dependent on STM32F7_DMA2 not STM32F7_DMA1 - From Anthony Merlino (2019-08-09). - * arch/arm/include/cxd56xx/chip.h: The NVIC priority correction of - commit c300f271303e04d5a7a1e42973a02115ed062cb0 must be applied to the - CXD56xx too. From Gregory Nutt (2019-08-10). - * - arch/arm/src/{stm32/stm32f7/stm32h7/stm32l4}/stm32_pwm.c: Configure - multi-channel duty only if channel specified.

From Gregory Nutt (2019-08-10). - * wireless/ieee802154/mac802154_netdev: Allow 64-bit prefix to be - configurable when auto-configuring the IPv6 address during bring-up. - Previously, the link-local prefix fe80::/64 was used. Also, put the - network in the DOWN state at the end of initialization. From Anthony - Merlino (2019-08-10). - * wireless/ieee8021254: Adds support for energy detect. Adds support - for energy detect by introducing a new radio call/callback, as the PHY - layer is required to perform the energy detect. From Anthony Merlino - (2019-08-10). - * MAC attributes - - wirelesss/ieee802154/mac802154: Makes comment more clear that it's - related to an outbound frame, not an incoming frame. - - wireless/ieee802154: Adds support for getting/setting - macMaxFrameRetries via IOCTL - - wireless/.ieee802154/mac802154: Add get support for rxonidle - attribute - From Anthony Merlino (2019-08-10). - * wirelesss/ieee802154/mac802154: Moves iobuffer into macnet struct so - that more than one macnet dev can exist. From Anthony Merlino - (2019-08-10). - * drivers/usbdev/rndis: Expose option to change number of write requests - that can be in flight. From Anthony Merlino (2019-08-10). - * net/ipforward: Check if interface is up early on when forwarding to - avoid extra work. As noticed in a previous wireless commit, when - forwarding is enabled and a packet comes in, the packet is attempted to - be sent on each other netdev without regard for whether it is in the UP - state. Of course this is eventually caught, but it can be caught - earlier to avoid unnecessary work, especially in the 6LoWPAN case where - a useless packet conversion will occur. From Anthony Merlino - (2019-08-10). - * clock.h: Copies in missing function documentation from C file. From - Anthony Merlino (2019-08-10). - * ieee802154: Support dynamic FCS length. Adds - IEEE802154_ATTR_PHY_FCSLEN. This change introduces - IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to set/get - the FCS length that's added to the end of the frame. One use case, in - promiscuous mode, is to add back in the FCS of the received frame by - increasing the iob->io_len by the FCS length. From Anthony Merlino - (2019-08-10). - * wireless network devices: Attach radio to d_buf before registering - device to handle forwarding case. When CONFIG_NET_IPFORWARD is - enabled, and CONFIG_NET_6LOWPAN is being used, a packet that attempts - to get forwarded on the 6LoWPAN interface will require that the radio's - buffer be attached to d_buf. Otherwise the below exception will be - hit. ~line 542 of sixlowpan_framelist.c: - - ... - /* Recover the reassembly buffer from the driver d_buf. */ - - reass = (FAR struct sixlowpan_reassbuf_s *)radio->r_dev.d_buf; - DEBUGASSERT(reass != NULL); - ... - - The underlying "radio" in this case is the mac802154_netdev. This - behavior has probably not been observed because the buffer is normally - attached in the periodic txpoll worker. However, in my case, the - 6LoWPAN interface was not UP yet, and therefore the worker hadn't run - yet. From Anthony Merlino (2019-08-10). - * mac802154: Fixes issues with extended address. 1) Extended address - should be read-only. 2) Extended address should be placed in frame in - "reverse-canonical" order. The extended address is a read-only - attribute and thus an attempt to write the extended address should be - denied. Instead, the extended address should really be either set by - the PHY/radio itself, or provided at board bring-up time to the radio - layer. The MAC layer now pulls in the extended address from the radio - any time the MAC is reset. The extended address is also supposed to be - sent in the frame in reverse-canonical order. This is very confusing in - the standard and it wasn't until I realized it was backwards in - Wireshark that I researched this further. Searching online I find - documents from the committee for suggestions/feedback on the future - standard. It isn't in the 2015 standard but a newer version of the - standard will presumably clarify this. It says that the extended - address should be written in reverse-canonical form, meaning the OUI - comes last, not first inside the frame. From Anthony Merlino - (2019-08-10). - * mac802154: Fixes issue where the txdesc's ackreq flag was not being - set, despite the frame containing a Frame Control field with ACKREQ bit - set. From Anthony Merlino (2019-08-10). - * arch/arm/src/stm32f7: Exposes stm32_flash_xxx functions. From Anthony - Merlino (2019-08-10). - * libs/libc/grp and pwd: Revisit file locks.

From - Pavel Pisa (2019-08-13). - * libs/libc/libc.csv: Correct dependency of setlocale on - CONFIG_LIBC_LOCALE. From Pavel Pisa (2019-08-13). - * symtab/, tools/: NuttX provides lists of available syscalls and - library functions and tools to process them. The lists can be used to - build symbol table which allows runtime program loading which can reuse - functions already compiled into NuttX system image. List processing, - compilation and linking to the final system image has been possible - only under manual control until now. Provided changes add option - (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of - available functions and syscalls automatically. The symbolic table is - generated in form libsymtab.a which can be reused by application or - directly pull in when "g_symtab" and "g_nsymbols" variables are - requested by EXECFUNCS configuration. I have tried to follow - mechanisms for library compilation in different kernel protection modes - but tested only flat no-MMU build. The basic assumption is that this - library and libraries providing syscall stubs and C-library functions - are available in user-space context and initial application (usually - NSH) registers the symbol table through IOCTL. The table can be reused - then by another applications in their address space as kernel allows. - Simple for flat or protected mode, I am not sure if really support in - MMU mode. It is highly probable that I have made some mistake, - overlooked something, but functionality is optional (should not cause - troubles in any mode if disabled) and main purpose is to lower memory - overhead when more applications are loaded on memory constrained system - which usually use direct kernel calling without protection or address - space separation. If the table should be provided by kernel to - applications then makefiles has to be adjusted. From Pavel Pisa - (2019-08-13). - * symtab/Makefile: The OS symbol table should not be generated in the - PROTECTED and KERNEL build modes. In those modes, the applications - should link with libproxy which will provide symbol-compatible access - to OS functions via a call gate.

From Pavel Pisa (2019-08-13). - * arch/arm/src/lpc17xx_40xx/lpc17_40_can.c: If BOARD_CCLKSEL_DIVIDER is - not equal to 1 on LPC178x or LPC40xx then base clock rate is calculated - incorrectly because CCLK frequency does not correspond to PLL0 clock - which is used for PCLK. This is partially workaround solution. It - would be probably better to define BOARD_PCLK_FREQUENCY even for - LPC176x targets and use that to replace divisor by base_clock in - up_dev_s.

In PROTECTED and KERNEL build - modes, then can be reached from applications only via a system call. - Unfortunately this is overly complex because there is a (soft) limit - of 6 parameters in a system call; task_spawn has seven parameters. - This is a soft limit but still difficult to extend because it involves - assembly language changes to numerous architectures. Better to get - more creative. Rather than extend the maximum number of parameters - across all architectures, I opted instead to marshal the seven - parameters into a structure and pass only a signle parameter: A - pointer to the structure containing the seven marshaled parameters. - From Gregory Nutt (2019-08-23). - * STM32H7: Memory Map DBGMCU is @ 0x5c001000 From David Sidrane - (2019-08-23). - * tools/refresh.sh: Fix some remaining breakage from the boards/ - directory reorganization.

From - Michael Jung (2019-08-25). - * arch/arm/src/stm32/stm32_spi.c: TI Synchronous Serial Frame Format. - The SPI macros on STM32 MCUs do support the Texas Instruments - Synchronous Serial Frame Format protocol (TI protocol). Defined a new - SPIDEV_MODETI and add support for it in stm32_spi.c. From Michael - Jung (2019-08-25). - * boards/boardctl.c and libs/libc/builtin: The BINFS file system uses - the same builtin library and builtin arrays as does NSH. The builtin - arrays are simple name-value pairs that map builtin function names - with the user-space entry point. In the FLAT build, the builtin - arrays are available everywhere via the backdoor left open by the FLAT - address space. In the PROTECTED build, however, the kernel must - maintain its own reference to the user-space builtin array. This - commits adds those kernel globals and a new - boardctl(BOARDIOC_BUILTINS) that can be used by applications to the - provide the builtin list reference to the kernel. From Gregory Nutt - (2019-08-25). - * libs/symtab: move symtab/ to libs/symtab. Let's no clutter up the - top level directory. Shorten CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYSTAB - to just CONFIG_EXECFUNCS_SYSTEM_SYMTAB. Some items in - syscall/syscall.csv are only valid when CONFIG_LIB_SYSCALL is - defined. That is always defined when really building the system - calls, but causes errors in libs/symtab because they are not valid in - the normal, FLAT build context. From Gregory Nutt (2019-08-25). - * arch/arm/src/samd2l2/sam_i2c_master.c: Correct time calculation. - From Bernd Walter (2019-08-26). - * Migrate CXD56xx common code to the common/ directory - - Move boot to common - - Move flash to common - - Move I2C driver to common - - Move uid to common - - Add SPH.

From Pavel Pisa (2019-08-28). - * tools/mkexport.sh: The export of gnu-elf.ld at least is required to - build ELF loadable binaries. Option to link system into different - memory locations (boot, application after boot-loader, RAM) without - need to rebuild/reexport NuttX is useful as well.

From Markus Bernet (2019-08-28). - * arch/arm/src/imxrt/hardware/imxrt_enc.h: Fix some errors in register - bit definitions. Noted by Arie de Muijnck. From Gregory Nutt - (2019-08-28). - * arch/arm/src/stm32h7/stm32_ethernet.c: Correct stm32h7 mac address - filtering. Correct the MAC address 0 register definition and remove - the 'receive all' flag. Now the Ethernet driver only receives packets - addressed to correct MAC. From Jukka Laitinen (2019-08-28). - * arch/arm/src/stm32h7/stm32_ethernet.c: Correct memory corruption - error. The Ethernet driver initialization incorrectly wrote to - DMACRXCR instead of DMACSR when trying to clear the stopped flags. - This caused invalid buffer length in the DMACRXCR, causing DMA to - overflow the RX buffers when large packets are sent to the device. - From Jukka Laitinen (2019-08-28). - * drivers/sensors/adt7320.c: Add support for the ADT7320 temperature - sensor. From Augusto Fraga Giachero (2019-08-28). - * The non-standard, non-portable type cpu_set_t was created specifically - to support the NuttX internal, SMP implementation. Any resemblance to - any other cpu_set_t would be purely coincidental. However it appears - that that coincidence has occurred. cpu_set_t has an equivalent, - non-standard, non-portable type in the GNU C library. Compilation of - libgnat expects this non-standard type to be defined. Who am I to - stand in the way of progress? This commit removes the conditioning on - CONFIG_SMP so that cpu_set_t is typed (as a uint8_t) even if - CONFIG_SMP is not defined. Reference: Bitbucket issue 164. From - Gregory Nutt (2019-08-29). - * arch/arm/src/stm32/stm32_adc.c: Add ADC calibration procedure for - IP_ADC_V1. Tested on STM32F100, and it magically increased result - accuracy. STM32F103 has the same calibration procedure. I am not - sure about others. From Matous Pokorny (2019-08-29). - * net/inet and net/tcp: Fix tcp close flow; free the connection after - all tcp close process finished. From zhangyuan7 (2019-08-30). - * tools/Makefile.* and tools/mkexport.sh: This change allows to export - builtin applications registry into temporarily created directory where - export archive content is prepared. If the Makefile in apps directory - does not define export: target then error is print but export - continues without interruption. It would be more logical to print - warning but there is no way instruct apps make to not print error. - From Pavel Pisa (2019-08-30). - * boards/arm/lpc17xx_40xx/lx_cpu: Add support for the PIKRON LX_CPU - board. From Pavel Pisa (2019-08-30). - * board/Kconfig and board/README.txt: Add configuration support for the - LX_CPU board.

Rationale: Fully specify that this is the 212-pin BGA - package (ZAD ending) and for consistency with earlier changes to other - Tiva TM4C12x part numbers in Kconfig names and identifiers. From - Nathan Hartman (2019-08-30). - * tools/Makefile.win: Port changes of commit - 3ed844640d25b854457b6cc08f89d907072c0054 to Makefile.win. Untested - because I don't have a Windows native build platform setup. There - have been a lot of changes to the build system lately do to directory - re-organization so likely the native build is broken. Certainly - tools/configure.bat should be replaces with tools/configure.c. From - Gregory Nutt (2019-08-30). - * net/Kconfig: Ethernet packet buffer size cannot be permitted to go - below 1294 if IPv6 is selected. From Gregory Nutt (2019-08-31). - * net/: Now handles reception of IPv4 packets with larger IPv4 headers - containing options. From Gregory Nutt (2019-08-31). - * boards/arm/lpc17xx_40xx/lx_cpu/configs/nsh/defconfig: Correct shit - defconfig file. Recent patch dumped a prohibited .config file as the - defconfig file when a proper defconfig file created via 'make - savdefconfig' is required. Bad. From Gregory Nutt (2019-08-31). - * arch/arm/src/stm32/stm32_adc.c: Correct an error found in build - testing. Recent commit to add STM32F1 calibration was not properly - conditioned. Caused compilation errors on all STM32 F2 family - members. From Gregory Nutt (2019-08-31). - * arch/arm/src/stm32/stm32_adc.c: Another fix. adc_calibrate() was - called even when it was conditioned out, causing a link time failure. - From Gregory Nutt (2019-08-31). - * net/: Re-order the content of all address-family socket 'connection' - structures so that they begin with a common prologue. This permits - better use of logic for different address family types. From Gregory - Nutt (2019-09-01). - * net/local/local_conn.c: Removed unnecessary memset(). Connection - structure is allocated with kmm_zalloc() which will clear all memory. - From Gregory Nutt (2019-09-01). - * boards/Board.mk: Add support to pass dependency paths. - boards/arm/cxd56xx/common/Makefile: Add correct dependency paths for - board/ and src/ subdirectories. From Gregory Nutt (2019-09-01). - * net/arp/arp.h: Remove an unused structure definition. From Gregory - Nutt (2019-09-01). - * gs2200m supports SIOCGIFHWADDR From Masayuki Ishikawa (2019-09-02). - * drivers/timers/pwm.c: Move the pwm/pwm.c driver to timers/pwm.c, The - drivers/pwm contained only one .c file (pwm.c), so to avoid the - proliferation of sub-directories inside drivers/ is better to move the - pwm.c driver to drivers/timers. The pwm.h header was moved to - include/nuttx/timers to keep consistency, so all files referencing it - need to be updated. From Augusto Fraga Giachero (2019-09-02). - * libc/libc/unistd/: Add stubs for geteuid(), getegid(), seteuid(), and - setegid(). NuttX does not currently support effective user/group IDs, - but these stubs will support linkage of applications that expect these - POSIX standard interfaces. From Gregory Nutt (2019-09-03). - * libc/libc/unistd/: Add stubs for setreuid(), and setregid(). NuttX - does not currently support effective user/group IDs, but these stubs - will support linkage of applications that expect these POSIX standard - interfaces. From Gregory Nutt (2019-09-03). - * arch/arm/src/arm/up_fullcontextrestore.S: When performing stability - test, the application would cause kernel crash. When I trace the - stack, I find that register R1 has been changed, and its value is the - same as register CPSR. In up_fullcontextrestore.S, the restoration of - R0 and R1 is not atomic: 'msr cpsr r1 will enable interrupts and the - recovery of r0 and r1 may be interrupted and the value or R1 may be - changed. Fix is to use a single ldmia to restore R0, R1, and return - via R15. From Loyen Wang (2019-09-04). - * drivers/sensors/isl29023.c: Add basic driver of ISL29023 ambient - light sensor. The basic driver can set operational mode, range, and - resolution. It can also read lux value in continuous mode. Interrupt - and the alarm is not implemented.

From Adam Porter (2019-09-08). - * STM32F7/H7/L4 OTG host: Adam Porter's fix for STM32 FS/HS probably - should be applied to STM32 F7, H7, and L4 OTG host which are very - similar. From Gregory Nutt (2019-09-08). - * EFM32 OTG host: Adam Porter's fix for STM32 FS/HS probably should be - applied to EFM32 host which which has very similar IP.

From Oki Minabe (2019-09-08). - * drivers/ioexpander/gpio_lower_half.c: Remove limitation when pintype - > GPIO_INTERRUPT_PIN. From ligd (2019-09-09). - * STM32, STM32F7, STM32H7, STM32L4, and EFM32 USB Host: This change was - required to get my devices (CDC-MBIM) to enumerate. Initially the - system timed out retrieving the USB configuration descriptor. Ctrl IN - requests got nothing but NAKs. I found that the initial SETUP packet - and corresponding IN transfer were fine; it was the Status OUT phase - that was getting the NAK. After receiving a NAK on the Status OUT, - the code would loop back and issue another ctrl IN, which will always - fail because the data was already transferred before. Thus the entire - transfer would 'timeout'. The fix I implemented moves the DATANAK - timeout loop to only apply to the Status OUT. Of course this worked - for my devices, but maybe isn't the right solution in general. I - think that both the ctrl IN and the Status OUT need their own retry - loops? From Adam Porter (2019-09-09). - * tools/mkexport.sh: Export LDSCRIPT and STRIP definition and align - with Makefile.export. From Pavel Pisa (2019-09-10). - * boards/arm/lpc17xx_40xx/lx_cpu/configs/nsh/defconfig: Tested - ETHRENET, UARTs, heap in external SDRAM, use of symbol tables for - applications loading over TFTP and kernel modules insertion. USB and - SD card enabled but there are some issues (probably config or IO - ports) still. From Pavel Pisa (2019-09-10). - * sched/sched_rrgetinterval.c: sched_get_rr_interval() should return - {0,0} if round-robin scheduling is not selected for the task. From - Gregory Nutt (2019-09-10). - * include/sys/types.h: Remove non-standard HP-UX priority range - definitions. HP-UX is not a supported OS. From Gregory Nutt - (2019-09-10). - * Fix typos, 1 in a #define, others in comments. This changes one - definition: _MQ_TIMEDRECIEVE is changed to _MQ_TIMEDRECEIVE. It - appears this symbol is not used anywhere. From Nathan Hartman - (2019-09-11). - * boards/z80: Correct path to linker script in all boards using the - ZDS-II toolchain. Yet more fallout from the big boards/ directory - re-organization. From Gregory Nutt (2019-09-11). - * boards/: Several more fixes to Make.defs files and README.txt files. - More collateral damage from the big boargs/ directory - re-organization. From Gregory Nutt (2019-09-11). - * boards/arm/imx6/sabre-6quad/scripts/Make.defs: Yet another boards/ - re-organization fix-up. From Gregory Nutt (2019-09-11). - * libs/libc/builtin/: builtin_isavail() should not set the errno - variable because this functions may be used by internal OS logic for - which setting the errno variable would be inappropriate. From Gregory - Nutt (2019-09-11). - * boards/arm/stm32f0l0g0/nucleo-g071rb/scripts/ld.script: Fix - .ARM.exidx section overlap with .data From Daniel Pereira Volpato - (2019-09-11). - * Modify all files from 2eb4fe5ffb7dee21b33 to use solution from Daniel - P. Volpato. From Alan Carvalho de Assis (2019-09-11). - * Modify all a few more linker scripts missed in 415e3d34482012ab308, - probably because they were created after 2eb4fe5ffb7dee21b33. From - Gregory Nutt (2019-09-11). - * Move EXIDX-related assignments inside of braces so that we can be - assure that the symbols have the correct alignment. Suggested by - Daniel P. Volpato From Gregory Nutt (2019-09-12). - * boards/arm/tiva/tm4c123g-launchpad/scripts/tm4c123g-launchpad.ld: Add - alignments for the TMC4123G-LaunchPad as well. From Nathan Hartman - (2019-09-12). - * boards/arm/stm32/axoloti, omnibusf4, and stm32f4discovery: If - CONFIG_SCHED_CRITMONITOR is selected, then make sure that ITM and DWT - resources are enabled before accessing ITM and DWT registers. By - default, these registers are disabled. Suggested by Juha Niskanen. - From Gregory Nutt (2019-09-13). - -8.2 2019-11-16 Gregory Nutt - - * drivers/mtd/gd25.c: Add support for a new FLASH vendor.

From Xiang Xiao (2019-09-15). - * All linker scripts: Preface all _ebss definitions with . = ALIGN(4). - Otherwise, the last bytes in the .bss section will not be initialized - properly. Also convert all linker scripts that use TABs to spaces. - From Gregory Nutt - (2019-09-15). - * All linker scripts: Preface all _edata definitions with . = ALIGN(4). - Otherwise, the last bytes in the .data section may not be initialized - properly. Also convert all linker scripts indent in units of 8-spaces - to units of 4-spaces. From Gregory Nutt (2019-09-15). - * tools/configure.*: Add -s option to skip .config/Make.defs existence - check. From Xiang Xiao (2019-09-16). - * tools/Makefile.unix: Fix build error when issue 'make -B'. mkdir: - cannot create directory 'staging': File exists: - tools/Makefile.unix:269: recipe for target 'staging' failed' From - Xiang Xiao (2019-09-16). - * drivers/syslog: syslog_force does not set errno so do not test - against it. Some changes to comments. From Juha Niskanen (2019-09-16). - * Large Ethernet packet can leads network halt From Bazooka Joe - (2019-09-16). - * boards/mips Linker Scripts: The PIC32M* start-up code initializes - .bss by writing 16 bytes at a time in a loop. The start (_sbss) - alignment is only required to be 4 bytes since the write is done with - 4 store instructions. In a previous change, the end address, _ebss, - was aligned to 16 byte to prevent initializing past the end off the - .bss region. However, that does not work unless the start address, - _sbss, is also aligned to 16 bytes. From Gregory Nutt - (2019-09-16). - * arch/arm/src/stm32h7/stm32_ethernet.c: Bazooka Joe's fix to the STM32 - F7 Ethernet driver (ec4a7be5c2540207042669e10cc4134e108dae02) should - be applied to the H7 as well. The other STM32 Ethernet driver already - has the change. From Gregory Nutt (2019-09-16). - * Kconfig and arch/Kconfig: Add some protection so that you cannot - select an architecture-specific header file if the architecture does - not provide the header file. From Gregory Nutt (2019-09-16). - * libs/libc/math/Kconfig: Should select the NuttX float.h file - automatically if the NuttX math library is selected.

From Gregory Nutt - (2019-09-18). - * net/ipforward, tcp, and udp: Fix a chicken and egg problem by - eliminating the check of the arp/neighbor tables before packet - transmission - 1. For buffered tcp/udp case, if - CONFIG_NET_ARP_SEND/CONFIG_NET_ARP_IPIN / CONFIG_NET_ICMPv6_NEIGHBOR - isn't enabled and the table doesn't contain ip<->ethaddr mapping - yet, the logic will skip the realtransmission and then arp/neighbor - can't steal the final buffer to generate arp/icmpv6 packet. - 2. For all other cases, the tcp layer or user program should already - contain the retransmit logic, the check is redundancy and may - generate many duplicated packets if arp/icmpv6 response is too slow - because the cursor stop forward. If user still concern about the - very first packet lost, he could fix the issue by - enabling CONFIG_NET_ARP_SEND/CONFIG_NET_ICMPv6_NEIGHBOR at begin. - From Xiang Xiao (2019-09-18). - * stm32h7 SDMMC support IDMA, Interrupt driven, pullups and SDIO - - stm32h7: Supports ARMV7M Stack check - - stm32h7: sdmmc bug fix writting address 0 - - stm32h7: sdmmc Clean up timming - - stm32f7: Kconfig typos, formating - - stm32f7: sdmmc use binary not - - stm32f7: nxstyle formatting - - stm32h7: SDMMC Kconfig add Block Setup, Preflight, Delayed Invalidate - - stm32h7: Correct value of ICR reset - - stm32h7: SDMMC support IDMA, Interrupt driven, pullups and SDIO - - stm32h7: Add AXI - - stm32h7: Workaround for Errata 2.2.9 Reading from AXI SRAM may lead - to data read corruption - From David Sidrane (2019-09-19). - * tools/configure.sh and configure.c: Do not remove CONFIG_SIM_M32 if - host is specified.

From - Bernd Walter (2019-09-24). - * net/icmpv6/icmpv6_rnotify.c: Correct a bad index in debug output. - From Bernd Walter (2019-09-25). - * net/inet/inet_close.c: Fixes two problems, both noted by Bernd Walter: - 1) Prior to this change the 'pstate' variable was non-NULL only when - doing a lingering close. Comments to this effect as well as tests - of pstate should also have been updated. These are confusing and - inappropriate, but do not lead to incorrect behavior. - 2) Eliminate an incomplete test when a disconnection event. When a - disconnection event occurs, the close logic MUST always terminate - the wait. The conditional test was not incorrect, however, it - lacked 'else' logic and would simply ignore that disconnection - event in some cases. That is bad because there may not be another - disconnection event and that can lead to hangs (or - at least very, very long delays). From Gregory Nutt (2019-09-25). - * cxd56xx: various fixes - - arch: arm: cxd56xx: Support to set any i2c frequency.

So it is desirable - that the initial value of the LNA power is off by default. - - boards: cxd56xx: Remove initial setting of PIN_AP_CLK. PIN_AP_CLK is - used as a port selector of SDIO expander on the extension board, - and is set output low in initalizing. Therefore, this pin cannot be - used for other board. To avoid this restriction, remove this initial - operation because this pin is pulled down by default on the - extension board.

In - previous implementation, up_disable_irq() was called before recovering - local context. However, I noticed a deadlock happens in the following - situation. For example, if up_sigdevliver() is in progress on CPU0 and - CPU1 has called up_cpu_paused to CPU0, hence g_cpu_irqlock has been - locked by CPU1, in this case, we would see a deadlock in later call of - enter_critical_section() to restore irqcount. - To avoid this situation, we need to call enter_critical_section() to - break the deadlock. From Masayuki Ishikawa (2019-10-04). - * armv7-a and xtensa: Apply Masayuki Ishakawa's change to these these - other SMP architectures as well.

There is not relationship be - CONFIG_STM32_USBHOST and CONFIG_USBHOST, yet they they are used - interchangeably. This means that can (and did) get out of synch - causing link time failures. This change adds logic to select - CONFIG_USBHOST when CONFIG_STM32_USBHOST is selected, keeping the two - settings synchronized. Furthermore, since CONFIG_STM32_USBHOST is the - authoritative setting, all occurrences of CONFIG_USBHOST were replaced - with CONFIG_STM32_USBHOST in the architecture code and in this one - board code that was producing the error in build testing.

This change sets the - BBSRAM memory range to non-cacheable. - From David Sidrane (2019-11-08). - * net/netlink/netlink_route.c: Add Netlink socket NETLINK_ROUTE support - for getting a snopshot of the Neighbor table. - net/neighbor/neighbor_snapshot.c: Add neighbor_snapshot() that will - eventually be used by the Netlink sockets. Also fixed naming - violation 'struct neighbor_entry' -> 'struct neighbor_entry_s'. - include/nuttx/net/neighbor.h: Expose format of the IPv6 neighbor - table for use with Netlink sockets. - From Gregory Nutt (2019-11-08). - * arch/arm/src/stm32l4/stm32l4_idle.c: (1) Added BEGIN_IDLE() / - END_IDLE() to stop call so that we also get notification via LED of - the STOP mode, (2) Added the stm32l4_clockenable call as previously - discussed, and (3) Added call to pm_changestate() to inform drivers - we're back to running after the call to stm32l4_stop() returns. From - Matias N (2019-11-08). - * This change, initially for the imxrt1050, separates out the pinmux and - iomux functions cleanly. For ease of conversion default IOMUX - definitions have been added into imxrt_iomux.h. The change effectively - does two things; - (1) Unifies the iomux definitions - previously some pins had them, and - some didn't. This effectively made it impossible to use the - pinmuxes without editing the header file in the standard - distribution tree. - (2) Unifies the pin definitions so that every pin now has a suffix. - This makes it *much* easier to see when a pin is in use in your - code, because it will always have a definition in your board.h file. - For anyone who is already using this CPU, a couple of small changes - are needed to existing code; - - In respect of (1) add IOMUX decorators to your pin definitions. - You will find defaults in haardware/imxrt_iomux.h. Every pin - should have a IOMUX decorator and in general the defaults should - be OK. - - In respect of (2) you will need to add selectors for any function - that previously only had one pinning option. There aren't many of - those but LPUART1 is a good example. That just means adding into - your board.h something like; From Dave Marples (2019-11-08). - * boards/arm/imxrt/imxrt1020-evk: Add support for the MIMXRT1021-EVK - board.

From Gregory Nutt (2019-11-09). - * drivers/power/pm: Historically, the NuttX PM subsystem has consisted - of two functional components: (1) an "Upper" part that detects state - changes based on a random walk driven by activity levels, and (2) and - "lower" part that implements the state changes. - This change decouples that upper activity-based logic from the lower - random walk logic and allows use of other upper state detection logic - (such as a custom, application-specific state machine). - From Matias Nitsche (2019-11-09). - * boards/arm/imxrt/imxrt1020-evk/include/board.h: Fix an error that I - introduced with code review.

From Xiang Xiao (2019-11-11). - * drivers/rptun/rptun.c: vring size should also be aligned. From ligd - (2019-11-11). - * boards/arm/imxrt/imxrt1020-evk: Fix ifdef string. The old configs - folder was migrated to Boards/ and we should fix the ifdef. - From Alin Jerpelea (2019-11-11). - * boards/arm/imxrt/imxrt1020-evk: Make naming of the LED consistent. - In most places it is referred to as LED1. In board.h it is referred - to as USERLED1. The i.MXRT1020-EVK hardware user guide (HUG) uses the - name USERLED. This command makes all names internally consistent and - consistent with the HUG. Noted by Alin Jerpelea. From Gregory Nutt - (2019-11-11). - * arch/sim/ and boards/sim/sim/sim: Support OpenAMP between two - simulator instances.

From Alin Jerpelea (2019-11-12). - * drivers/power/activity_governor.c: Fix timer can't start when meet - very small pmtick. From ligd (2019-11-12). - * arch/arm/src/imxrt/imxrt_idle.c: Y'all remember that conversation we - had about why WFI might have been disabled on imxrt? Well, looks like - we found the reason: - - https://github.com/zephyrproject-rtos/zephyr/pull/8535/commits: - "The imxrt1050 is configured to use SYSTICK for the kernel timer, but - SYSTICK cannot wake up the soc from low-power modes. Disable - low-power modes on this soc until we have support for an alternative - timer." - "This fixes k_sleep on the EVKB version of the mimxrt1050_evk board. - An earlier version of the board (EVK, not EVKB), had A0 silicon which - by default did not enter low-power mode on a wfi." - - This change reverts the WFI enable for further investigation post - 8.2. With this change in place together with the previous one my - system is fully stable(*), just drinking a bit more power than I'd - like. From Dave Marples (2019-11-12). - * drivers/mtd/gd25.c: Add gd25_lock/unlock to case: enable 4-bytes - address From ligd (2019-11-12). - * arch/arm/src/imxrt/imxrt_serial.c: o, just to complete the - documentation of this...it looks like two issues, which confused me - greatly: - 1) Operational issue. TC (Transmission complete) and TDRE (TX Buffer - Empty) were transposed in imxrt_serial.c. The end result was that - for unoptimised code everything worked fine, but optimised code - got itself into a real mess and continually fired interrupts. The - change attached fixes this. This one would have been found much - more quickly if this particular board had supported SWO :-/ - 2) Startup issue. There are a number of chip errata that apply to - the 1052 first revision (A-suffix) that don't apply to the second - (B-suffix). Those got me for a while and it's important to use an - EVK_B_ dev board if you're suffering stability problems with this - particular chip. However, even with that resolved with either - optimised or unoptimised code when there is no SNVS (Battery - Backup) power and the power is switched on the CPU appears to boot - but gets stuck with timer interrupts not being generated. The CPU - is running and it will execute linear code. I have determined - this by putting an 'imxrt_lowputc('A'+irq)' into up_doirq. For the - non-running case the output looks like this: - - LLLL - - this implies 4 0x0b interrupts have been generated, and nothing - else. If I hit keys on the keyboard I get 'e' in the flow. 0x0b - is the SVC instruction and is the mechanism by which NuttX handles - task switching. 'e' is 0x24, which corresponds to the LPUART1 - interrupt. Other than these, the system does not respond further - but is happily in the idle loop. In this circumstance if you hit - SW2 on the EVKB board though the logjam 'unjams' and normal - service is established, output now looks like: - - LLLLPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPLPP ...etc. - - Where 'P' is 0x0f (the SYSTICK interrupt)....this is what _should_ - be happening so; SYSTICK starts up after SW2 has been pressed. - From this point on everything works correctly and you can reboot - the CPU, put new code into it or do whatever you wish, **provided - power is not cycled off**. If power is cycled off then return to - the top and go through the process again. When there is SNVS - power to the CPU then power can be switched on and off as you - wish, and the CPU will boot correctly. This has been determined by - putting 3V onto J6. - I think we are probably doing something naughty with the way we - are starting the clocks to the timers. There are certainly some - restrictions on imxrt clock manipulation which we have studiously - avoided. I am investigating further and have some potential - patches but even if I find the root cause it should not be - included in 8.2 as the change could be disruptive. - From Dave Marples (2019-11-12). - * net/netlink: Add options to disable individual NETLINK_ROUTE - commands. This will probably become quite large and will need to be - higher tunable for smaller platforms. From Gregory Nutt (2019-11-12). - * libs/libc/stdio/lib_getdelim.c: Add implementations of the POSIX - functions getdelim() and getline(). From Gregory Nutt (2019-11-12). - * libs/libc/stdio/lib_libfgets.c: Because of how the function is - defined, getline() canot be used on platforms that use CR-LF line - terminations. From Gregory Nutt (2019-11-12). - * include/sys/time.h, libs/libc/unistd, sched/timer: Implement - alarm(), setitimer() and getitimer() APIs. From liuhaitao - (2019-11-13). - * libs/libc/stdio/lib_getdelim.c: Make getdelim() behave per - specification on OpenGroup.org. Specifically, needs to reallocate - buffer if more data is received than will fit. From Gregory Nutt - (2019-11-13). - * libs/libc/stdio/lib_getdelim.c: Initial allocation should be larger; - incremental reallocs should be smaller. Update some comments. From - Gregory Nutt (2019-11-13). - * arch/renesas/include and arch/renesas/src: Fix spurious '=' in - comments. From David Sidrane (2019-11-14). - * drivers/syslog/ramlog.c: Fix ramlog readers never woken up when using - ramlog as syslog or console. We also make an attempt to avoid the - thundering herd problem if there are multiple readers/pollers. - Change also removes forcing CONFIG_RAMLOG_CRLF in - uttx/syslog/ramlog.h as there is no point of wasting precious RAM for - useless characters. From Juha Niskanen (2019-11-14). - * boards/arm/imxrt/imxrt1060-evk/src/imxrt_lcd.c: Because - board-private GPIO definitions have been moved to the public board.h - (VERY BAD IDEA), breakage happened in all files that need GPIO - definitions, but did not include board.h (which they should not have - to). From Gregory Nutt (2019-11-14). - * include/netpacket/netlink.h: Add definitions that will be needed for - future NETLINK_CRYPTO support. From Gregory Nutt (2019-11-14). - * syscall/: Implementation of syscall for new getitimer and setitimer - were incomplete. - include/sys/syscall.h: Should be SYS_getitimer and SYS_setitimer, - not SYS_getitime and SYS_setitime. - From Gregory Nutt (2019-11-14). - * syscall/ and include/sys/syscall.h: Fix an inconsistency. In - some places, getitimer() and setitimer() depend on - CONFIG_DISABLE_POSIX_TIMERS=n and in other places they depend on - nothing. As a result, there are link failures when - CONFIG_DISABLE_POSIX_TIMERS=y. Which is correct? On one hand, these - interfaces are not POSIX timers, so conditioning them on - CONFIG_DISABLE_POSIX_TIMERS. I opted to keep the dependence and just - apply it consistently. I did this because setitimer() and - getitimer() are seldom used so it is really best if a system call is - no generated for them in all cases.

NuttX may also be installed and built on Windows system + if you also provide such a POSIX development environment. Options for a + POSIX development environment under Windows include: + + - An installation of Linux on a virtual machine (VM) in Windows. I have + not been happy using a VM myself. I have had stability problems with + open source VMs and commercial VMs cost more than I want to spend. + Sharing files with Linux running in a VM is awkward; sharing devices + connected to the Windows box with Linux in a VM is, at the very least, + confusing; Using Windows tools (such as Segger J-Link) with files + built under the Linux VM is not a possibility. + + - The Cygwin environment. Instructions for installation of Cygwin on a + Windows system are provided in the following paragraph, "Installing + Cygwin". Cygwin is a mature, well-tested, and very convenient + environment. It is especially convenient if you need to + integrate with Windows tools and files. Downsides are that the + installation time is very long and the compile times are slow. + + - Ubuntu/Bash shell under Windows 10. This is a new option under + Windows 10. See the section "Ubuntu Bash under Windows 10" below. + This is an improvement over Cygwin if your concern is compile time; + its build performance is comparable to native Linux, certainly better + than the Cygwin build time. It also installs in a tiny fraction of + the time as Cygwin, perhaps 20 minutes for the basic Ubuntu install + (vs. more than a day for the complete Cygwin install). + + There have been even more recent ports of Linux environment to + Windows. I need to update this section to include some mention of + these alternatives. + + - The MSYS environment. MSYS derives from an older version of Cygwin + simplified and adapted to work more naturally in the Windows + environment. See if you are + interested in using MSYS. The advantages of the MSYS environment is + that it is better integrted with the native Windows environment and + lighter weight; it uses only a minimal number of add-on POSIX-land + tools. + + The download link in that Wiki takes you to the SourceForge download + site. The SourceForge MSYS project has been stagnant for some time. + The MSYS project has more recently moved to + . Downloads of current .zip + files are available there but no instructions for the installation. + + - MSYS2 appears to be a re-write of MSYS based on a newer version of + Cygwin. Is it available at . A windows + installer is available at that site along with very good installation + instructions. The download is relatively quick (at least compared to + Cygwin) and the 'pacman' package management tool supports supports + simple system updates. For example, 'pacman -S git' will install the + GIT command line utilities. + + - Other POSIX environments. Check out: + + - UnxUtils: , + + - MobaXterm: + - Gow: + + **Disclaimer**: In principle, these should work. However, I have never + used any of these environments and cannot guarantee that there is + not some less-than-obvious issues. + +NuttX can also be installed and built on a native Windows system, but with +some potential tool-related issues (see the discussion "Native Windows +Build" under "Building NuttX" below). GNUWin32 is used to provide +compatible native windows tools. + +## Installing Cygwin + +Installing Cygwin on your Windows PC is simple, but time consuming. See + for installation instructions. Basically you just +need to download a tiny setup.exe program and it does the real, network +installation for you. + +Some Cygwin installation tips: + + 1. Install at `C:\cygwin` + + 2. Install **everything**: "Only the minimal base packages from the + Cygwin distribution are installed by default. Clicking on categories + and packages in the setup.exe package installation screen will + provide you with the ability to control what is installed or updated. + Clicking on the "Default" field next to the "All" category will + provide you with the opportunity to install every Cygwin package. + Be advised that this will download and install hundreds of megabytes + to your computer." + +If you use the "default" installation, you will be missing many +of the Cygwin utilities that you will need to build NuttX. The +build will fail in numerous places because of missing packages. + +NOTE: The last time I installed **everything**, the download was +about 5GiB. The server I selected was also very slow so it took +over a day to do the whole install! + +NOTE: You don't really have to install **everything** but I cannot +answer the question "Then what should I install?" I don't know +the answer to that and so will continue to recommend installing +**everything**. + +You should certainly be able to omit "Science", "Math", and +"Publishing". You can try omitting KDE, Gnome, GTK, and other +graphics packages if you don't plan to use them. + +Perhaps a minimum set would be those packages listed below for the +"Ubuntu Bash under Windows 10" installation? + +**UPDATE**: Sergey Frolov had success with the following minimal +Cygwin configuration: + + 1. After starting the Cygwin installer, keep the recommended + packages that are pre-selected in the default configuration. + + 2. Using the installation tools, add the following packages: + + make (GNU make) bison libgmp3-dev + gcc-core byacc libmpfr-dev + gcc-g++ gperf libmpc-dev + flex gdb automake-1.15 + libncurses-dev libgmp-dev curl + +After installing Cygwin, you will get lots of links for installed +tools and shells. I use the RXVT native shell. It is fast and reliable +and does not require you to run the Cygwin X server (which is neither +fast nor reliable). Unless otherwise noted, the rest of these +instructions assume that you are at a bash command line prompt in +either Linux or in Cygwin shell. + +## Using MSYS + +MSYS is an environment the derives from Cygwin. Thus, most things said +about Cygwin apply equally to MSYS. This section will, then, focus on +the differences when using MSYS, specifically MSYS2. + +Here is it assumed that you have already downloaded and installed MSYS2 +from https://www.msys2.org using the windows installer available at that +location. It is also assumed that you have brought in the necessary +tools using the 'pacman' package management tool Tools needed including: + + pacman -S git + pacman -S make + pacman -S gcc + pacman -S gdb + +And possibly others depending upon your usage. Then you will need to +build and install kconfig-frontends per the instructions of the top-level +README.txt file in the tools repository. This requires the following +additional tools: + + pacman -S bison + pacman -S curl + pacman -S gperf + pacman -S ncurses-devel + pacman -S automake-wrapper + pacman -S autoconf + pacman -S pkg-config + +Because of some versioning issues, I had to run 'aclocal' prior to +running the kconfig-frontends configure script. See "Configuring NuttX" +below for further information. + +Unlike Cygwin, MSYS does not support symbolic links. The 'ln -s' command +will, in fact, copy a directory! This means that you Make.defs file will +have to include definitions like: + + ifeq ($(CONFIG_WINDOWS_MSYS),y) + DIRLINK = $(TOPDIR)/tools/copydir.sh + DIRUNLINK = $(TOPDIR)/tools/unlink.sh + endif + +This will force the directory copies to work in a way that can be handled +by the NuttX build system. NOTE: The default link.sh script has been +updated so that is should now be MSYS2 compatible. The above is preferred +but no longer necessary in the Make.defs file. + +To build the simulator under MSYS, you also need: + + pacman -S zlib-devel + +It appears that you cannot use directory names with spaces in them like +"/c/Program\ Files \(86\)" in the MSYS path variable. I worked around this +by create Windows junctions like this: + + 1. Open the a windows command terminal, + + 2. cd to `c:\msys64`, then + + 3. `mklink /j programfiles "C:/Program\ Files"` and + + 4. `mklink /j programfiles86 "C:/Program\ Files\ \(x86\)"` + + They then show up as `/programfiles` and `/programfiles86` with the MSYS2 + sandbox. Those paths can then be used with the PATH variable. I had + to do something similar for the path to the GNU Tools "ARM Embedded + Toolchain" which also has spaces in the path name. + +## Ubuntu Bash under Windows 10 + +A better version of a command-line only Ubuntu under Windows 10 (beta) +has recently been made available from Microsoft. + +### Installation + +Installation instructions abound on the Internet complete with screen +shots. I will attempt to duplicate those instructions in full here. +Here are the simplified installation steps: + + - Open *Settings*. + + - Click on *Update & security*. + + - Click on *For Developers*. + + - Under *Use developer features*, select the *Developer mode* option to + setup the environment to install Bash. + + - A message box should pop up. Click *Yes* to turn on developer mode. + + - After the necessary components install, you'll need to restart your + computer. + + Once your computer reboots: + + - Open *Control Panel*. + + - Click on *Programs*. + + - Click on *Turn Windows features on or off*. + + - A list of features will pop up, check the *Windows Subsystem for Linux + (beta)* option. + + - Click *OK*. + + - Once the components installed on your computer, click the *Restart + now* button to complete the task. + + After your computer restarts, you will notice that Bash will not appear in + the *Recently added* list of apps, this is because Bash isn't actually + installed yet. Now that you have setup the necessary components, use the + following steps to complete the installation of Bash: + + - Open *Start*, do a search for `bash.exe`, and press *Enter*. + + - On the command prompt, type `y` and press Enter to download and install + Bash from the Windows Store. This will take awhile. + + - Then you'll need to create a default UNIX user account. This account + doesn't have to be the same as your Windows account. Enter the + username in the required field and press Enter (you can't use the + username `admin`). + + - Close the `bash.exe` command prompt. + + Now that you completed the installation and setup, you can open the Bash + tool from the Start menu like you would with any other app. + +### Accessing Windows Files from Ubuntu + +File systems will be mounted under `/mnt` so for example `C:\Program Files` +appears at `/mnt/c/Program Files`. This is as opposed to Cygwin where +the same directory would appear at `/cygdrive/c/Program Files`. + +With these differences (perhaps a few other Windows quirks) the Ubuntu +install works just like Ubuntu running natively on your PC. + +A good tip for file sharing is to use symbolic links within your Ubuntu +home directory. For example, suppose you have your `projects` directory +at `C:\Documents\projects`. Then you can set up a link to the `projects/` +directory in your Ubuntu directory like: + + ln -s /mnt/c/Documents/projects projects + +### Accessing Ubuntu Files From Windows + +In Ubuntu Userspace for Windows, the Ubuntu file system root directory is +at: + + %localappdata%\lxss\rootfs + +Or + + C:\Users\Username\AppData\Local\lxss\rootfs + +However, I am unable to see my files under the rootfs\home directory. +After some looking around, I find the home directory +`%localappdata%\lxss\home`. + +With that trick access to the `/home` directory, you should actually be +able to use Windows tools outside of the Ubuntu sandbox with versions of +NuttX built within the sandbox using that path. + +### Executing Windows Tools from Ubuntu + +You can also execute Windows tools from within the Ubuntu sandbox: + + /mnt/c/Program\ Files\ \(x86\)/Microchip/xc32/v1.43/bin/xc32-gcc.exe --version + Unable to translate current working directory. Using C:\WINDOWS\System32 + xc32-gcc.exe (Microchip Technology) 4.8.3 MPLAB XC32 Compiler v1.43 Build date: Mar 1 2017 + ... + +The error message indicates that there are more issues: You cannot mix +Windows tools that use Windows style paths in an environment that uses +POSIX paths. I think you would have to use Linux tools only from within +the Ubuntu sandbox. + +### Install Ubuntu Software + +Use `sudo apt-get install `. As examples, this is how +you would get GIT: + + sudo apt-get install git + +This will get you a compiler for your host PC: + + sudo apt-get install gcc + +This will get you an ARM compiler for your target: + + sudo apt-get install gcc-arm-none-eabi + +**NOTE**: That is just an example. I am not sure if apt-get will give you a +current or usable compiler. You should carefully select your toolchain +for the needs of your project. + +You will also need to get the kconfig-frontends configuration as +described below under *NuttX Configuration Tool*. In order to build the +kconfig-frontends configuration tool you will also need: `make`, `gperf`, +`flex`, `bison`, and `libncurses-dev`. + +That is enough to do a basic NuttX build. + +### Integrating with Windows Tools + +If you want to integrate with Windows native tools, then you would need +deal with the same kind of craziness as with integrating Cygwin with +native toolchains, see the section *Cygwin Build Problems* below. + +However, there is currently no build support for using Windows native +tools with Ubuntu under Windows. This tool combination is made to work +with Cygwin through the use of the `cygpath -w` tool that converts paths +from say `/cydrive/c/Program Files` to `C:\Program Files`. There is, +however, no corresponding tool to convert `/mnt/c/Program Files` in the +Ubuntu environment. + +### Graphics Support + +The Ubuntu version support by Microsoft is a command-line only version. +There is no support for Linux graphics utilities. + +This limitation is not a limitation of Ubuntu, however, only in what +Microsoft is willing to support. If you install a X-Server, then you +can also use basic graphics utilities. See for example: + + + +Many Linux graphics programs would, however, also require a graphics +framework like GTK or Qt. So this might be a trip down the rabbit hole. + +### Using macOS + +You need to install at least the following tools specific to macOS +if you want to build the sim: + + * Xcode (the native compiler and the rest of the toolchain) + + * ELF toolchain (if you want to build modules for CONFIG_LIBC_MODLIB) + + brew install x86_64-elf-gc + +# INSTALLATION + +There are two ways to get NuttX: You may download released, stable +tarballs from either the project website. Or you may get NuttX by +cloning the GIT repositories. Let's consider the released tarballs +first: + +## Download and Unpack + +Download and unpack the NuttX tarball. If you are reading this, then +you have probably already done that. After unpacking, you will end +up with a directory called nuttx-version (where version is the NuttX +version number). You might want to rename that directory nuttx to +match the various instructions in the documentation and some scripts +in the source tree. + + * Download location: + + + + * Legacy download locations: + + + + +## Semi-Optional apps/ Package + +All NuttX libraries and example code used to be in included within +the NuttX source tree. As of NuttX-6.0, this application code was +moved into a separate tarball, the apps tarball. If you are just +beginning with NuttX, then you will want to download the versioned +apps tarball along with the NuttX tarball. If you already have your +own product application directory, then you may not need the apps +tarball. + +It is called "Semi-optional" because if you don't have some `apps/` +directory, NuttX will *fail* to build! You do not necessarily need +to use the NuttX apps tarball but may, instead, provide your own +custom application directory. Such a custom directory would need +to include a valid Makefile to support the build and a valid Kconfig +file to support the configuration. More about these files later. + +Download then unpack the apps tarball in the same directory where you +unpacked the NuttX tarball. After you unpack the apps tarball, you +will have a new directory called apps-version (where the version +should exactly match the version of the NuttX tarball). Again, you +might want to rename the directory to simply apps/ to match what +you read in the documentation + +After unpacking (and renaming) the apps tarball, you will have two +directories side by side like this: + + | + +----+----+ + | | + nuttx/ apps/ + +This is important because the NuttX build will expect to find the +apps directory in that (default) location. That default location +can be changed by modifying your NuttX configuration file, but that +is another story. + +## Installation Directories with Spaces in the Path + +The nuttx build directory should reside in a path that contains no +spaces in any higher level directory name. For example, under +Cygwin, your home directory might be formed from your first and last +names like: `/home/First Last`. That will cause strange errors when +the make system tries to build. + +[Actually, that problem is probably not too difficult to fix. Some + Makefiles probably just need some paths within double quotes] + +I work around spaces in the home directory name, by creating a +new directory that does not contain any spaces, such as `/home/nuttx`. +Then I install NuttX in `/home/nuttx` and always build from +`/home/nuttx/nuttx-code`. + +## Downloading from Repositories + +### Cloning the Repository + +**BEFORE** cloning repositories on any Windows platform do the following GIT +command: + + git config --global core.autocrlf false + +That will avoid conversions of linefeeds (newlines, \n) to carriage +return plus linefeed sequences (\r\n) + +The current NuttX du jour is available in from a GIT repository. Here are +instructions for cloning the core NuttX RTOS (corresponding to the nuttx +tarball discussed above): + + git clone https://gitbox.apache.org/repos/asf/incubator-nuttx.git nuttx + +-or- + + git clone https://github.com/apache/incubator-nuttx.git nuttx + +And the semi-optional apps/ application directory and be cloned like: + + git clone https://gitbox.apache.org/repos/asf/incubator-nuttx-apps.git apps + +-or- + + git clone https://github.com/apache/incubator-nuttx-apps.git apps + +That will give you the same directory structure like this: + + | + +----+----+ + | | + nuttx/ apps/ + +### Configuring the Clones + +The following steps need to be performed for each of the repositories. +After changing to the clone directory: + +Set your identity: + + git config --global user.name "My Name" + git config --global user.email my.name@example.com + +Colorized diffs are much easier to read: + + git config --global color.branch auto + git config --global color.diff auto + git config --global color.interactive auto + git config --global color.status auto + +Checkout other settings + + git config --list + +### Cloning NuttX Inside Cygwin + +If you are cloning the NuttX repository, it is recommended to avoid +automatic end of lines conversions by git. These conversions may break +some scripts like configure.sh. Before cloning, do the following: + + git config --global core.autocrlf false + +## Related Repositories + +These are standalone repositories: + + * + or + + + This directory holds an optional package of applications and libraries + can be used with the NuttX RTOS. There is a README.txt file there that + will provide more information about that package. + + * + + This is the NuttX C++ graphics support. This includes NxWM, the tiny + NuttX Window Manager. + + * + + This repository contains a version of the uClibc++ C++ library. This code + originates from and has been adapted for NuttX by the + RGMP team (). + + * + + A environment that you can to use to build a custom, NuttX GNU toolchain. + + * + + There are snapshots of some tools here that you will need to work with + NuttX: kconfig-frontends, genromfs, and others. + +## Notes about Header Files + +### Other C-Library Header Files + +When a GCC toolchain is built, it must be built against a C library. +The compiler together with the contents of the C library completes the +C language definition and provides the complete C development +environment. NuttX provides its own, built-in C library. So the +complete, consistent C language definition for use with NuttX comes from +the combination of the compiler and the header files provided by the +NuttX C library. + +When a GCC toolchain is built, it incorporates the C library header +files into the compiler internal directories and, in this way, the C +library really becomes a part of the toolchain. If you use the NuttX +buildroot toolchain as described below under "NuttX Buildroot +Toolchain", your GCC toolchain will build against the NuttX C library +and will incorporate the NuttX C library header files as part of the +toolchain. + +If you use some other, third-party tool chain, this will not be the +case, however. Those toolchains were probably built against some +other, incompatible C library distribution (such as newlib). Those +tools will have incorporated the incompatible C library header files +as part of the toolchain. These incompatible header files must *not* +be used with NuttX because they will conflict with definitions in the +NuttX built-in C-Library. For such toolchains that include header +files from a foreign C-Library, NuttX must be compiled without using +the standard header files that are distributed with your toolchain. +This prevents including conflicting, incompatible header files such +as stdio.h. + +The math.h and stdarg.h are probably the two most trouble some header +files to deal with. These troublesome header files are discussed in +more detail below. + +### Header Files Provided by Your Toolchain + +Certain header files, such as `setjmp.h`, `stdarg.h`, and `math.h`, may still +be needed from your toolchain and your compiler may not, however, be able +to find these if you compile NuttX without using standard header files +(i.e., with `-nostdinc`). If that is the case, one solution is to copy +those header file from your toolchain into the NuttX include directory. + +### Duplicated Header Files + +There are also a few header files that can be found in the `nuttx/include` +directory which are duplicated by the header files from your toolchain. +stdint.h and stdbool.h are examples. If you prefer to use the `stdint.h` +and `stdbool.h` header files from your toolchain, those could be copied +into the `nuttx/include/` directory. Using most other header files from +your toolchain would probably cause errors. + +### math.h + +Even though you should not use a foreign C-Library, you may still need +to use other, external libraries with NuttX. In particular, you may +need to use the math library, libm.a. NuttX supports a generic, built-in +math library that can be enabled using `CONFIG_LIBM=y`. However, you may +still want to use a higher performance external math library that has +been tuned for your CPU. Sometimes such tuned math libraries are +bundled with your toolchain. + +The math library header file, `math.h`, is a then special case. If you do +nothing, the standard math.h header file that is provided with your +toolchain will be used. + +If you have a custom, architecture specific math.h header file, then +that header file should be placed at `arch//include/math.h`. There +is a stub `math.h` header file located at `include/nuttx/lib/math.h`. This stub +header file can be used to "redirect" the inclusion to an architecture- +specific math.h header file. If you add an architecture specific math.h +header file then you should also define `CONFIG_ARCH_MATH_H=y` in your +NuttX Configuration file. If `CONFIG_ARCH_MATH_H` is selected, then the +top-level Makefile will copy the stub math.h header file from +`include/nuttx/lib/math.h` to `include/math.h` where it will become the system +`math.h` header file. The stub `math.h` header file does nothing other +than to include that architecture-specific `math.h` header file as the +system `math.h` header file. + +### float.h + +If you enable the generic, built-in math library, then that math library +will expect your toolchain to provide the standard `float.h` header file. +The float.h header file defines the properties of your floating point +implementation. It would always be best to use your toolchain's `float.h` +header file but if none is available, a default `float.h` header file will +be provided if this option is selected. However, there is no assurance +that the settings in this `float.h` are actually correct for your platform! + +### stdarg.h + +In most cases, the correct version of stdarg.h is the version provided +with your toolchain. However, sometimes there are issues with +using your toolchains `stdarg.h`. For example, it may attempt to draw in +header files that do not exist in NuttX or perhaps the header files that +it uses are not compatible with the NuttX header files. In those cases, +you can use an architecture-specific `stdarg.h` header file by defining +`CONFIG_ARCH_STDARG_H=y`. + +See the discussion above for the `math.h` header. This setting works +exactly the same for the `stdarg.h` header file. + +# CONFIGURING NUTTX + +## Instantiating "Canned" Configurations + +### `configure.sh` and `configure.bat` + +"Canned" NuttX configuration files are retained in: + + boards////configs/ + +Where `` is the name of your development board and `` +is the name of the sub-directory containing a specific configuration for +that board. `` and `` refer to characteristics of the +MCU used on the board: `` is the CPU architecture implemented +by the MCU; `` identifies the MCU chip family. Only a few +steps are required to instantiate a NuttX configuration, but to make the +configuration even easier there are scripts available in the tools/ +sub-directory combines those simple steps into one command. + +There is one tool for use with any Bash-like shell that does configuration +steps. It is used as follows: + + tools/configure.sh : + +There is an alternative Windows batch file that can be used in the windows +native environment like: + + tools\configure.bat : + +And, to make sure that other platforms are supported, there is also a +C program at tools/configure.c that can be compiled to establish the +board configuration. + +See `tools/README.txt` for more information about these scripts. + +General information about configuring NuttX can be found in: + + {TOPDIR}/boards/README.txt + {TOPDIR}/boards////README.txt + +### The Hidden Configuration Scripts: + +As mentioned above, there are only a few simple steps to instantiating a +NuttX configuration. Those steps are hidden by the configuration scripts +but are summarized below: + + 1. Copy Files + + Configuring NuttX requires only copying two files from the + `` to the directory where you installed NuttX (TOPDIR): + + * Copy `boards////configs//Make.def` to `{TOPDIR}/Make.defs` + + OR + + * Copy `boards////scripts/Make.def` + to `{TOPDIR}/Make.defs` + + Make.defs describes the rules needed by your tool chain to compile + and link code. You may need to modify this file to match the + specific needs of your toolchain. NOTE that a configuration may + have its own unique Make.defs file in its configuration directory or + it may use a common Make.defs file for the board in the scripts/ + directory. The first takes precedence. + + * Copy `boards////configs//defconfig` to `{TOPDIR}/.config` + + The defconfig file holds the actual build configuration. This + file is included by all other make files to determine what is + included in the build and what is not. This file is also used + to generate a C configuration header at `include/nuttx/config.h`. + + * Copy other, environment-specific files to `{TOPDIR}` + + This might include files like .gdbinit or IDE configuration files + like .project or .cproject. + + 2. Refresh the Configuration + + New configuration setting may be added or removed. Existing settings + may also change there values or options. This must be handled by + refreshing the configuration as described below. + + NOTE: NuttX uses only compressed defconfig files. For the NuttX + defconfig files, this refreshing step is *NOT* optional; it is also + necessary to uncompress and regenerate the full making file. This is + discussed further below. + +## Refreshing Configurations + +Configurations can get out of date. As new configuration settings are +added or removed or as dependencies between configuration settings +change, the contents of a default configuration can become out of synch +with the build systems. Hence, it is a good practice to "refresh" each +configuration after configuring and before making. To refresh the +configuration, use the NuttX Configuration Tool like this: + + make oldconfig + +AFTER you have instantiated the NuttX configuration as described above. +The configuration step copied the .config file into place in the top-level +NuttX directory; 'make oldconfig' step will then operate on that .config +file to bring it up-to-date. + +If your configuration is out of date, you will be prompted by 'make oldconfig' +to resolve the issues detected by the configuration tool, that is, to +provide values for the new configuration options in the build system. Doing +this can save you a lot of problems down the road due to obsolete settings in +the default board configuration file. The NuttX configuration tool is +discussed in more detail in the following paragraph. + +Confused about what the correct value for a new configuration item should +be? Enter ? in response to the 'make oldconfig' prompt and it will show +you the help text that goes with the option. + +If you don't want to make any decisions are willing to just accept the +recommended default value for each new configuration item, an even easier +way is: + + make olddefconfig + +The olddefconfig target will simply bring your configuration up to date with +the current Kconfig files, setting any new options to the default value. +No questions asked. + +## NuttX Configuration Tool + +An automated tool has been incorporated to support re-configuration +of NuttX. This tool is based on the kconfig-frontends application available +at . (This +is a snapshot of the old +which is no longer available.) This application provides a tool called +`kconfig-mconf` that is used by the NuttX top-level Makefile. The following +make target is provided: + + make menuconfig + +This make target will bring up NuttX configuration menus. + +**WARNING**: Never do `make menuconfig` on a configuration that has +not been converted to use the kconfig-frontends tools! This will +damage your configuration (see +). + +How do we tell a new configuration from an old one? See "Incompatibilities +with Older Configurations" below. + +The `menuconfig` make target depends on two things: + + 1. The Kconfig configuration data files that appear in almost all + NuttX directories. These data files are the part that is still + under development (patches are welcome!). The Kconfig files + contain configuration information for the configuration settings + relevant to the directory in which the Kconfig file resides. + + NOTE: For a description of the syntax of this configuration file, + see kconfig-language.txt in the tools repository at + + + 2. The `kconfig-mconf` tool. `kconfig-mconf` is part of the + kconfig-frontends package. You can download that package from the + snapshot in the tools repository at . + + Building kconfig-frontends under Linux may be as simple as + `configure; make; make install` but there may be some build + complexities, especially if you are building under Cygwin. See + the more detailed build instructions in the top-level README.txt + file of the tools repository at . + + + The `make install` step will, by default, install the `kconfig-mconf` + tool at `/usr/local/bin/mconf`. Where ever you choose to + install `kconfig-mconf`, make certain that your PATH variable includes + a path to that installation directory. + + The kconfig-frontends tools will not build in a native Windows + environment directly "out-of-the-box". For the Windows native + case, you can use the modified version of kconfig-frontends + that can be found at + + + + or a more recent port that can be found at + + . + +The basic configuration order is "bottom-up": + + - Select the build environment, + - Select the processor, + - Select the board, + - Select the supported peripherals + - Configure the device drivers, + - Configure the application options on top of this. + +This is pretty straight forward for creating new configurations +but may be less intuitive for modifying existing configurations. + +Another ncurses-based tool that is an option to kconfig-mconf is +kconfig-nconf. The differences are primary in in the aesthetics of the +UI. If you have kconfig-nconf built, then you can invoke that front end +with: + + make nconfig + +If you have an environment that supports the Qt or GTK graphical systems +(probably KDE or gnome, respectively, or Cygwin under Windows with Qt or +GTK installed), then you can also build the graphical kconfig-frontends, +kconfig-qconf and kconfig-gconf. In these case, you can start the +graphical configurator with either: + + make qconfig + + or + + make gconfig + +Some keyboard shortcuts supported by kconfig-mconf, the tool that runs +when you do 'make menuconfig': + + - `?` will bring up the mconfig help display. + + - `/` can be used find configuration selections. + + - `Z` can be used to reveal hidden configuration options + +These last two shortcuts are described further in the following +paragraphs. + +## Finding Selections in the Configuration Menus + +The NuttX configuration options have gotten complex and it can be very +difficult to find options in the menu trees if you are not sure where +to look. The "basic configuration order" describe above can help to +narrow things down. + +But if you know exactly what configuration setting you want to select, +say `CONFIG_XYZ`, but not where to find it, then the `make menuconfig` +version of the tool offers some help: By pressing the '/' key, the +tool will bring up a menu that will allow you to search for a +configuration item. Just enter the string `CONFIG_XYZ` and press ENTER. +It will show you not only where to find the configuration item, but +also all of the dependencies related to the configuration item. + +## Reveal Hidden Configuration Options + +If you type `Z`, then `kconfig-mconf` will change what is displayed. +Normally, only enabled features that have all of their dependencies met +are displayed. That is, of course, not very useful if you would like to +discover new options or if you are looking for an option and do not +realize that the dependencies have not yet been selected and, hence, it +is not displayed. + +But if you enter `Z`, then every option will be shown, whether or not its +dependencies have been met. You can then see everything that could be +selected with the right dependency selections. These additional options +will be shown the `-` for the selection and for the value (since it +cannot be selected and has no value). About all you do is to select +the `` option to see what the dependencies are. + +## Make Sure that You are on the Right Platform + +Saved configurations may run on Linux, Cygwin (32- or 64-bit), or other +platforms. The platform characteristics can be changed use `make +menuconfig`. Sometimes this can be confusing due to the differences +between the platforms. Enter `sethost.sh` + +sethost.sh is a simple script that changes a configuration to your +host platform. This can greatly simplify life if you use many different +configurations. For example, if you are running on Linux and you +configure like this: + + tools/configure.sh board:configuration + +The you can use the following command to both (1) make sure that the +configuration is up to date, AND (2) the configuration is set up +correctly for Linux: + + tools/sethost.sh -l + +Or, if you are on a Windows/Cygwin 64-bit platform: + + tools/sethost.sh -c + +Or, for MSYS/MSYS2: + + tools/sethost.sh -g + +Other options are available from the help option built into the +script. You can see all options with: + + tools/sethost.sh -h + +Recently, the options to the configure.sh (and configure.bat) scripts have +been extended so that you both setup the configuration, select for the host +platform that you use, and uncompress and refresh the defconfig file all in +one command like: + + tools/configure.sh -l board:configuration + +For a Linux host or for a Windows/Cygwin host: + + tools/configure.sh -c board:configuration + +Other options are available from the help option built into the +script. You can see all options with: + + tools/configure.sh -h + +## Comparing Two Configurations + +If you try to compare two configurations using 'diff', you will probably +not be happy with the result. There are superfluous things added to +the configuration files that make comparisons with the human eye +difficult. + +There is a tool at nuttx/tools/cmpconfig.c that can be built to simplify +these comparisons. The output from this difference tool will show only +the meaningful differences between two configuration files. This tool is +built as follows: + + cd nuttx/tools + make -f Makefile.host + +This will create a program called 'cmpconfig' or 'comconfig.exe' on Windows. + +Why would you want to compare two configuration files? Here are a few +of the reasons why I do this + + 1. When I create a new configuration I usually base it on an older + configuration and I want to know, "What are the options that I need to + change to add the new feature to the older configurations?" For example, + suppose that I have a boardA/nsh configuration and I want to create a + boardA/nxwm configuration. Suppose I already have boardB/nsh and + boardB/nxwm configurations. Then by comparing the boardB/nsh with the + boardB/nxwm I can see the modifications that I would need to make to my + boardA/nsh to create a new boardA/nxwm. + + 2. But the most common reason that I use the 'cmpconfig' program is to + check the results of "refreshing" a configuration with 'make oldconfig' + (see the paragraph "Refreshing Configurations" above). The 'make + oldconfig' command will make changes to my configuration and using + 'cmpconfig', I can see precisely what those changes were and if any + should be of concern to me. + + 3. The 'cmpconfig' tool can also be useful when converting older, legacy + manual configurations to the current configurations based on the + kconfig-frontends tools. See the following paragraph. + +## Making `defconfig` Files + +### `.config` Files as `defconfig` Files: + +The minimum `defconfig` file is simply the generated `.config` file with +CONFIG_APPS_DIR setting removed or commented out. That setting provides +the name and location of the `apps/` directory relative to the `nuttx` build +directory. The default is `../apps/`, however, the apps directory may be +any other location and may have a different name. For example, the name +of versioned NuttX releases are always in the form `apps-xx.yy` where `xx.yy` +is the version number. + +### Finding the `apps/` Directory Path: + +When the default configuration is installed using one of the scripts or +programs in the NuttX tools directory, there will be an option to provide +the path to the `apps/` directory. If not provided, then the configure tool +will look around and try to make a reasonable decision about where the +`apps/` directory is located. + +### Compressed `defconfig` Files: + +The `Makefile` also supports an option to generate very small `defconfig` +files. The `.config` files are quite large and complex. But most of the +settings in the `.config` file simply have the default settings from the +`Kconfig` files. These `.config` files can be converted into small `defconfig` +file: + + make savedefconfig + +That make target will generate a defconfig file in the top-level +directory. The size reduction is really quite remarkable: + + wc -l .config defconfig + 1085 .config + 82 defconfig + 1167 total + +In order to be usable, the `.config` file installed from the compressed +defconfig file must be reconstituted using: + + make olddefconfig + + > **NOTE 1**: Only compressed defconfig files are retained in the NuttX repository. + > All patches and PRs that attempt to add or modify a defconfig file MUST + > use the compressed defconfig format as created by 'make savdefconfig.' + + > **NOTE 2**: When 'make savedefconfig' runs it will try several things some of + > which are expected to fail. In these cases you will see an error message + > from make followed by "(ignored)." You should also ignore these messages + +**CAUTION**: This size reduction was accomplished by removing all setting +from the `.config` file that were at the default value. `make olddefconfig` +can regenerate the original `.config` file by simply restoring those default +settings. The underlying assumption here is, of course, that the default +settings do not change. If the default settings change, and they often +do, then the original `.config` may not be reproducible. + +So if your project requires 100% reproducibility over a long period of +time, you make want to save the complete `.config` files vs. the standard, +compressed `defconfig` file. + +### Configuring with "Compressed" defconfig Files: + +As described above `defconfig`, all NuttX `defconfig` files are compressed +using `make savedeconfig`. These compressed `defconfig` files are +generally not fully usable as they are and may not build the target +binaries that you want because the compression process removed all of +the default settings from the `defconfig` file. To restore the default +settings, you should run the following after configuring: + + make olddefconfig + +That will restore the the missing defaulted values. + +Using this command after configuring is generally a good practice anyway: +Even if the `defconfig` files are not "compressed" in this fashion, the +`defconfig` file may be old and the only way to assure that the installed +`.config` is is up to date is via `make oldconfig` or `make olddefconfig`. +See the paragraph above entitled "Refreshing Configurations" for +additional information. + +## Incompatibilities with Older Configurations + +**WARNING** + +The current NuttX build system supports *only* the new compressed, +`defconfig` configuration files generated using the `kconfig-frontends` tools +as described in the preceding section. Support for the older, legacy, +manual configurations was eliminated in NuttX 7.0; support for +uncompressed `.config-files-as-defconfig` files was eliminated after +NuttX-7.21. All configurations must now be done using the +`kconfig-frontends` tool. The older manual configurations and the new +`kconfig-frontends` configurations are not compatible. Old legacy +configurations can *not* be used with the `kconfig-frontends` tool and, +hence, cannot be used with releases of NuttX 7.0 and beyond: + +If you run `make menuconfig` with a legacy configuration the resulting +configuration will probably not be functional. + + > Q: How can I tell if a configuration is a new kconfig-frontends + > configuration or an older, manual configuration? + > + > A: Only old, manual configurations will have an appconfig file + > + > Q: How can I convert a older, manual configuration into a new, + > kconfig-frontends toolchain. + > + > A: Refer to + +**WARNING** + +As described above, whenever you use a configuration, you really should +always refresh the configuration with the following command *before* you +make NuttX: + + make oldconfig + +OR + + make olddefconfig + +This will make sure that the configuration is up-to-date in the event that +it has lapsed behind the current NuttX development (see the paragraph +"Refreshing Configurations" above). But this only works with *new* +configuration files created with the kconfig-frontends tools. + +Further, this step is *NOT* optional with the new, compressed defconfig +files. It is a necessary step that will also uncompress the defconfig +file, regenerating the `.config` and making it usable for NuttX builds. + +Never do `make oldconfig` (OR `make menuconfig`) on a configuration that +has not been converted to use the kconfig-frontends tools! This will +damage your configuration (see +). + +## NuttX Configuration Tool under DOS + + Recent versions of NuttX support building NuttX from a native Windows + console window (see *Native Windows Build* below). But `kconfig-frontends` + is a Linux tool. At one time this was a problem for Windows users, but + now there are two specially modified versions of the `kconfig-frontends` + tools that can be used. One can be found here: + + + The configuration steps of the most recent versions of NuttX require the + `kconfig-tweak` tool that is not not available in the the above. However, + there has been an update to this `Kconfig` Windows tools that does include + `kconfig-tweak`: http://reclonelabs.com/more-kconfig-awesomeness-for-windows/ + + Source code is available here: + and + + It is also possible to use the version of `kconfig-frontends` built + under Cygwin outside of the Cygwin *sandbox* in a native Windows + environment: + + 1. You can run the configuration tool using Cygwin. However, the + Cygwin `Makefile.win` will complain so to do this will, you have + to manually edit the `.config` file: + + a. Delete the line: `CONFIG_WINDOWS_NATIVE=y` + + b. Change the apps/ directory path, `CONFIG_APPS_DIR` to use Unix + style delimiters. For example, change `..\apps` to `../apps` + + And of course, after you use the configuration tool you need to + restore `CONFIG_WINDOWS_NATIVE=y` and the correct `CONFIG_APPS_DIR`. + + 2. You can, with some effort, run the Cygwin `kconfig-mconf` tool + directly in the Windows console window. In this case, you do not + have to modify the `.config` file, but there are other complexities: + + a. You need to temporarily set the Cygwin directories in the PATH + variable then run `kconfig-mconf` manually like: + + kconfig-mconf Kconfig + + There is a Windows batch file at `tools/kconfig.bat` that automates + these steps: + + tools/kconfig menuconfig + + b. There is an issue with accessing DOS environment variables from + the Cygwin `kconfig-mconf` running in the Windows console. The + following change to the top-level `Kconfig` file seems to work + around these problems: + + config APPSDIR + string + - option env="APPSDIR" + + default "../apps" + +# TOOLCHAINS + +## Cross-Development Toolchains + + In order to build NuttX for your board, you will have to obtain a cross- + compiler to generate code for your target CPU. For each board, + configuration, there is a `README.txt` file (at + `boards////README.txt`). + That README file contains suggestions and information about appropriate + tools and development environments for use with your board. + + In any case, the PATH environment variable will need to be updated to + include the location where the build can find the toolchain binaries. + +## NuttX Buildroot Toolchain + + For many configurations, a DIY set of tools is available for NuttX. These + tools can be downloaded from the NuttX Bitbucket.org file repository. After + unpacking the buildroot tarball, you can find instructions for building + the tools in the `buildroot/boards/README.txt` file. + + Check the README.txt file in the configuration directory for your board + to see if you can use the buildroot toolchain with your board (this + README.txt file is located in + `boards////README.txt`). + + This toolchain is available for both the Linux and Cygwin development + environments. + + Advantages: (1) NuttX header files are built into the tool chain, + and (2) related support tools like NXFLAT tools, the ROMFS + genromfs tools, and the kconfig-frontends tools can be built into your + toolchain. + + Disadvantages: This tool chain is not was well supported as some other + toolchains. GNU tools are not my priority and so the buildroot tools + often get behind. For example, until recently there was no EABI support + in the NuttX buildroot toolchain for ARM. + + NOTE: For Cortex-M3/4, there are OABI and EABI versions of the buildroot + toolchains. If you are using the older OABI toolchain the prefix for + the tools will be `arm-nuttx-elf-`; for the EABI toolchain the prefix will + be `arm-nuttx-eabi-`. If you are using the older OABI toolchain with + an ARM Cortex-M3/4, you will need to set CONFIG_ARMV7M_OABI_TOOLCHAIN + in the `.config` file in order to pick the right tool prefix. + + If the make system ever picks the wrong prefix for your toolchain, you + can always specify the prefix on the command to override the default + like: + + make CROSSDEV=arm-nuttx-elf + +# SHELLS + +The NuttX build relies on some shell scripts. Some are inline in the +Makefiles and many are executable scripts in the `tools/`. directory. The +scripts were all developed using bash and many contain bash shell +dependencies. + +Most of the scripts begin with `#!/bin/bash` to specifically select the +bash shell. Some still have `#!/bin/sh` but I haven't heard any complaints +so these must not have bash dependencies. + +There are two shell issues that I have heard of: + + 1. Linux where `/bin/sh` refers to an incompatible shell (like `ksh` or `csh`). + + In this case, bash is probably available and the `#!/bin/bash` at the + beginning of the file should do the job. If any scripts with `#!/bin/sh` + fail, try changing that to `#!/bin/bash` and let me know about the change. + + 2. FreeBSD with the Bourne Shell and no bash shell. + + The other, reverse case has also been reported on FreeBSD setups that + have the Bourne shell, but not bash. In this base, `#!/bin/bash` fails + but `#!/bin/sh` works okay. My recommendation in this case is to create + a symbolic link at `/bin/bash` that refers to the Bourne shell. + + There may still be issues, however, with certain the `bash`-centric scripts + that will require modifications. + +# BUILDING NUTTX + +## Building + +NuttX builds in-place in the source tree. You do not need to create +any special build directories. Assuming that your Make.defs is setup +properly for your tool chain and that PATH environment variable contains +the path to where your cross-development tools are installed, the +following steps are all that are required to build NuttX: + + cd {TOPDIR} + make + +At least one configuration (eagle100) requires additional command line +arguments on the make command. Read +`{TOPDIR}/boards////README.txt` to see +if that applies to your target. + +## Re-building + +Re-building is normally simple -- just type make again. + +But there are some things that can "get you" when you use the Cygwin +development environment with Windows native tools. The native Windows +tools do not understand Cygwin's symbolic links, so the NuttX make system +does something weird: It copies the configuration directories instead of +linking to them (it could, perhaps, use the NTFS `mklink` command, but it +doesn't). + +A consequence of this is that you can easily get confused when you edit +a file in one of the linked (i.e., copied) directories, re-build NuttX, +and then not see your changes when you run the program. That is because +build is still using the version of the file in the copied directory, not +your modified file! + +Older versions of NuttX did not support dependencies in this +configuration. So a simple work around this annoying behavior in this +case was the following when you re-build: + + make clean_context all + +This 'make' command will remove of the copied directories, re-copy them, +then make NuttX. + +However, more recent versions of NuttX do support dependencies for the +Cygwin build. As a result, the above command will cause everything to be +rebuilt (because it removes and will cause recreating the +`include/nuttx/config.h` header file). A much less gracefully but still +effective command in this case is the following for the ARM configuration: + + rm -rf arch/arm/src/chip arch/arm/src/board + +This "kludge" simple removes the copied directories. These directories +will be re-created when you do a normal 'make' and your edits will then be +effective. + +## Build Targets and Options + +### Build Targets + +Below is a summary of the build targets available in the top-level +NuttX Makefile: + + * `all` + + The default target builds the NuttX executable in the selected output + formats. + + * `clean` + + Removes derived object files, archives, executables, and temporary + files, but retains the configuration and context files and directories. + + * `distclean` + + Does 'clean' then also removes all configuration and context files. + This essentially restores the directory structure to its original, + unconfigured stated. + +Application housekeeping targets. The APPDIR variable refers to the user +application directory. A sample `apps/` directory is included with NuttX, +however, this is not treated as part of NuttX and may be replaced with a +different application directory. For the most part, the application +directory is treated like any other build directory in the `Makefile` script. +However, as a convenience, the following targets are included to support +housekeeping functions in the user application directory from the NuttX +build directory. + + * `apps_clean` + + Perform the clean operation only in the user application directory + + * `apps_distclean` + + Perform the distclean operation only in the user application directory. + The apps/.config file is preserved so that this is not a "full" distclean + but more of a configuration "reset" for the application directory. + + * `export` + + The export target will package the NuttX libraries and header files into + an exportable package. Caveats: (1) These needs some extension for the KERNEL + build. (2) The logic in tools/mkexport.sh only supports GCC and, for example, + explicitly assumes that the archiver is 'ar' + + * `download` + + This is a helper target that will rebuild NuttX and download it to the target + system in one step. The operation of this target depends completely upon + implementation of the DOWNLOAD command in the user Make.defs file. It will + generate an error an error if the DOWNLOAD command is not defined. + +The following targets are used internally by the make logic but can be invoked +from the command under certain conditions if necessary. + + * `depend` + + Create build dependencies. (NOTE: There is currently no support for build + dependencies under Cygwin using Windows-native toolchains.) + + * `context` + + The context target is invoked on each target build to assure that NuttX is + properly configured. The basic configuration steps include creation of the + the `config.h` and `version.h` header files in the `include/nuttx` directory and + the establishment of symbolic links to configured directories. + + * `clean_context` + + This is part of the `distclean` target. It removes all of the header files + and symbolic links created by the context target. + +### Build Options + +Of course, the value any make variable an be overridden from the make command +line. However, there is one particular variable assignment option that may +be useful to you: + + * `V=1` + + This is the build "verbosity flag." If you specify `V=1` on the make command + line, you will see the exact commands used in the build. This can be very + useful when adding new boards or tracking down compile time errors and + warnings (Contributed by Richard Cochran). + +## Native Windows Build + +The beginnings of a Windows native build are in place but still not often +used as of this writing. The build was functional but because of lack of +use may find some issues to be resolved with this build configuration. + +The windows native build logic initiated if CONFIG_WINDOWS_NATIVE=y is +defined in the NuttX configuration file: + +This build: + + - Uses all Windows style paths + - Uses primarily Windows batch commands from cmd.exe, with + - A few extensions from GNUWin32 + +In this build, you cannot use a Cygwin or MSYS shell. Rather the build must +be performed in a Windows console window. Here is a better terminal than the +standard issue, CMD.exe terminal: ConEmu which can be downloaded from: + or . + +Build Tools. The build still relies on some Unix-like commands. I use +the GNUWin32 tools that can be downloaded from +using the *Download all* selection. Individual packages can be download +instead if you know what you are doing and want a faster download (No, I +can't tell you which packages you should or should not download). + +NOTE: It should be possible to use Cygwin or MSYS2 in place of the GNUWin32 +tools. There are, however, complexities in doing that because those tools +depend on the shell environment and use DLLs that are not found (at least +not without the correct setup). + +Host Compiler: I use the MingGW GCC compiler which can be downloaded from +. If you are using GNUWin32, then it is recommended +the you not install the optional MSYS components as there may be conflicts. + +Kconfig-frontends: See the section entitled "NuttX Configuration Tool +under DOS" for information about installing the `kconfig-frontend` tools to +run natively under Windows. + +This capability should still be considered a work in progress because: + + 1. It has not been verified on all targets and tools, and + 2. it still lacks some of the creature-comforts of the more mature + environments. + +## Installing GNUWin32 + + The Windows native build will depend upon a few Unix-like tools that can be + provided either by MSYS or GNUWin32. The GNUWin32 are available from + . GNUWin32 provides ports of tools with a + GPL or similar open source license to modern MS-Windows (Microsoft Windows + 2000 / XP / 2003 / Vista / 2008 / 7). See + for a list of all of the tools + available in the GNUWin32 package. + + The SourceForge project is located here: + . The project is still being + actively supported (although some of the Windows ports have gotten very old). + + Some commercial toolchains include a subset of the GNUWin32 tools in the + installation. My recommendation is that you download the GNUWin32 tools + directly from the sourceforge.net website so that you will know what you are + using and can reproduce your build environment. + + GNUWin32 Installation Steps: + + The following steps will download and execute the GNUWin32 installer. + +1. Download `GetGNUWin32-x.x.x.exe` from + . This is the + installer. The current version as of this writing is 0.6.3. + +2. Run the installer. + +3. Accept the license. + +4. Select the installation directory. My recommendation is the + directory that contains this README file (``). + +5. After running `GetGNUWin32-0.x.x.exe`, you will have a new directory + `/GetGNUWin32` + + Note that the GNUWin32 installer didn't install GNUWin32. Instead, it + installed another, smarter downloader. That downloader is the GNUWin32 + package management tool developed by the Open SSL project. + + The following steps probably should be performed from inside a DOS shell. + +6. Change to the directory created by `GetGNUWin32-x.x.x.exe` + + cd GetGNUWin32 + +7. Execute the download.bat script. The download.bat script will download + about 446 packages! Enough to have a very complete Linux-like environment + under the DOS shell. This will take awhile. This step only downloads + the packages and the next step will install the packages. + + download + +8. This step will install the downloaded packages. The argument of the + install.bat script is the installation location. C:\gnuwin32 is the + standard install location: + + install C:\gnuwin32 + + **NOTE**: This installation step will install *all* GNUWin32 packages... far + more than you will ever need. If disc space is a problem for you, you might + need to perform a manual installation of the individual ZIP files that you + will find in the `/GetGNUWin32/packages` directory. + +9. Make sure that you add the GNUWin32 tools to your path variable: + + set PATH=C:\gnuwin32\bin;%PATH% + + **WARNING**: Make sure you have `C:\MinGW\bin` in your path before any other + directory that contains `libiconv-2.dll`. Apparently the `as.exe` in some + MinGW distributions are dependent on that DLL, and having an old + version of it in the path somewhere (for example GnuWin32 tools) will + cause as.exe to pick up the older version that doesn't have the entry + point it's looking for. + +# CYGWIN BUILD PROBLEMS + +## Performance + +Build performance under Cygwin is really not so bad, certainly not as good +as a Linux build. However, often you will find that the performance is +not just bad but terrible. If you are seeing awful performance.. like two +or three compilations per second.. the culprit is usually your Windows +Anti-Virus protection interfering with the build tool program execution. + +I use Cygwin quite often and I use Windows Defender. In order to get good +build performance, I routinely keep the Windows Defender "Virus & Threat +Protections Settings" screen up: I disable "Real-Time Protection" just +before entering 'make' then turn "Real-Time Protection" back on when the +build completes. With this additional nuisance step, I find that build +performance under Cygwin is completely acceptable. + +## Strange Path Problems + +If you see strange behavior when building under Cygwin then you may have +a problem with your PATH variable. For example, if you see failures to +locate files that are clearly present, that may mean that you are using +the wrong version of a tool. For example, you may not be using Cygwin's +'make' program at /usr/bin/make. Try: + + which make + /usr/bin/make + +When you install some toolchains (such as Yargarto or CodeSourcery tools), +they may modify your PATH variable to include a path to their binaries. +At that location, they may have GNUWin32 versions of the tools. So you +might actually be using a version of make that does not understand Cygwin +paths. + +The solution is either: + + 1. Edit your PATH to remove the path to the GNUWin32 tools, or + + 2. Put /usr/local/bin, /usr/bin, and /bin at the front of your path: + + export PATH=/usr/local/bin:/usr/bin:/bin:$PATH + +## Window Native Toolchain Issues + +There are many popular Windows native toolchains that may be used with NuttX. +Examples include CodeSourcery (for Windows), devkitARM, and several vendor- +provided toolchains. There are several limitations with using a and Windows +based toolchain in a Cygwin environment. The three biggest are: + + 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are + performed automatically in the Cygwin makefiles using the 'cygpath' utility + but you might easily find some new path problems. If so, check out 'cygpath -w' + + 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links + are used in NuttX (e.g., include/arch). The make system works around these + problems for the Windows tools by copying directories instead of linking them. + But this can also cause some confusion for you: For example, you may edit + a file in a "linked" directory and find that your changes had no effect. + That is because you are building the copy of the file in the "fake" symbolic + directory. If you use a Windows toolchain, you should get in the habit of + making like this: + + make clean_context all + + An alias in your .bashrc file might make that less painful. The rebuild + is not a long as you might think because there is no dependency checking + if you are using a native Windows toolchain. That bring us to #3: + +## General Pre-built Toolchain Issues + +To continue with the list of "Window Native Toolchain Issues" we can add +the following. These, however, are really just issues that you will have +if you use any pre-built toolchain (vs. building the NuttX toolchain from +the NuttX buildroot package): + +There may be incompatibilities with header files, libraries, and compiler +built-in functions detailed below. For the most part, these issues +are handled in the existing make logic. But if you are breaking new ground, +then you may encounter these: + + 1. Header Files. Most pre-built toolchains will build with a foreign C + library (usually newlib, but maybe uClibc or glibc if you are using a + Linux toolchain). This means that the header files from the foreign + C library will be built into the toolchain. So if you `#include `, + you will get the stdio.h from the incompatible, foreign C library and + not the nuttx `stdio.h` (at `nuttx/include/stdio.h`) that you wanted. + + This can cause confusion in the builds and you must always be + sure the `-nostdinc` is included in the `CFLAGS`. That will assure that + you take the include files only from + + 2. Libraries. What was said above header files applies to libraries. + You do not want to include code from the libraries of any foreign + C libraries built into your toolchain. If this happens you will get + perplexing errors about undefined symbols. To avoid these errors, + you will need to add `-nostdlib` to your `CFLAGS` flags to assure that + you only take code from the NuttX libraries. + + This, however, may causes other issues for libraries in the toolchain + that you do want (like `libgcc.a` or `libm.a`). These are special-cased + in most Makefiles, but you could still run into issues of missing + libraries. + + 3. Built-Ins. Some compilers target a particular operating system. + Many people would, for example, like to use the same toolchain to + develop Linux and NuttX software. Compilers built for other + operating systems may generate incompatible built-in logic and, + for this reason, `-fno-builtin` should also be included in your + C flags + + And finally you may not be able to use NXFLAT. + + 4. NXFLAT. If you use a pre-built toolchain, you will lose all support + for NXFLAT. NXFLAT is a binary format described in + Documentation/NuttXNxFlat.html. It may be possible to build + standalone versions of the NXFLAT tools; there are a few examples + of this in the buildroot repository at + However, it is possible that there could be interoperability issues + with your toolchain since they will be using different versions of + binutils and possibly different ABIs. + +## Building Original Linux Boards in Cygwin + +Some default board configurations are set to build under Linux and others +to build under Windows with Cygwin. Various default toolchains may also +be used in each configuration. It is possible to change the default +setup. Here, for example, is what you must do in order to compile a +default Linux configuration in the Cygwin environment using the +CodeSourcery for Windows toolchain. After instantiating a "canned" +NuttX configuration, run the target 'menuconfig' and set the following +items: + + Build Setup->Build Host Platform->Windows + Build Setup->Windows Build Environment->Cygwin + System Type->Toolchain Selection->CodeSourcery GNU Toolchain under Windows + +In Windows 7 it may be required to open the Cygwin shell as Administrator +("Run As" option, right button) you find errors like "Permission denied". + +## Recovering from Bad Configurations + +Many people make the mistake of configuring NuttX with the "canned" +configuration and then just typing `make` with disastrous consequences; +the build may fail with mysterious, uninterpretable, and irrecoverable +build errors. If, for example, you do this with an unmodified Linux +configuration in a Windows/Cgwin environment, you will corrupt the +build environment. The environment will be corrupted because of POSIX vs +Windows path issues and with issues related to symbolic links. If you +make the mistake of doing this, the easiest way to recover is to just +start over: Do `make distclean` to remove every trace of the corrupted +configuration, reconfigure from scratch, and make certain that the set +the configuration correctly for your platform before attempting to make +again. + +Just fixing the configuration file after you have instantiated the bad +configuration with 'make' is not enough. + +# DOCUMENTATION + +Additional information can be found in the Documentation/ directory and +also in README files that are scattered throughout the source tree.

Native Toolchain Issues - o Documentation - -ENVIRONMENTS -^^^^^^^^^^^^ - - NuttX requires a POSIX development environment such as you would find under - Linux or macOS. NuttX may also be installed and built on Windows system - if you also provide such a POSIX development environment. Options for a - POSIX development environment under Windows include: - - - An installation of Linux on a virtual machine (VM) in Windows. I have - not been happy using a VM myself. I have had stability problems with - open source VMs and commercial VMs cost more than I want to spend. - Sharing files with Linux running in a VM is awkward; sharing devices - connected to the Windows box with Linux in a VM is, at the very least, - confusing; Using Windows tools (such as Segger J-Link) with files - built under the Linux VM is not a possibility. - - - The Cygwin environment. Instructions for installation of Cygwin on a - Windows system are provided in the following paragraph, "Installing - Cygwin". Cygwin is a mature, well-tested, and very convenient - environment. It is especially convenient if you need to - integrate with Windows tools and files. Downsides are that the - installation time is very long and the compile times are slow. - - - Ubuntu/Bash shell under Windows 10. This is a new option under - Windows 10. See the section "Ubuntu Bash under Windows 10" below. - This is an improvement over Cygwin if your concern is compile time; - its build performance is comparable to native Linux, certainly better - than the Cygwin build time. It also installs in a tiny fraction of - the time as Cygwin, perhaps 20 minutes for the basic Ubuntu install - (vs. more than a day for the complete Cygwin install). - - There have been even more recent ports of Linux environment to - Windows. I need to update this section to include some mention of - these alternatives. - - - The MSYS environment. MSYS derives from an older version of Cygwin - simplified and adapted to work more naturally in the Windows - environment. See http://www.mingw.org/wiki/MSYS if you are - interested in using MSYS. The advantages of the MSYS environment is - that it is better integrted with the native Windows environment and - lighter weight; it uses only a minimal number of add-on POSIX-land - tools. - - The download link in that Wiki takes you to the SourceForge download - site. The SourceForge MSYS project has been stagnant for some time. - The MSYS project has more recently moved to - http://odsn.net/projects/sfnet_mingwbundle. Downloads of current .zip - files are available there but no instructions for the installation. - - - MSYS2 appears to be a re-write of MSYS based on a newer version of - Cygwin. Is it available at https://www.msys2.org. A windows - installer is available at that site along with very good installation - instructions. The download is relatively quick (at least compared to - Cygwin) and the 'pacman' package management tool supports supports - simple system updates. For example, 'pacman -S git' will install the - GIT command line utilities. - - - Other POSIX environments. Check out: - - UnxUtils: https://sourceforge.net/projects/unxutils/, - https://en.wikipedia.org/wiki/UnxUtils - MobaXterm: https://mobaxterm.mobatek.net/ - Gow: https://github.com/bmatzelle/gow/wiki - - Disclaimer: In principle, these should work. However, I have never - used any of these environments and cannot guarantee that there is - not some less-than-obvious issues. - - NuttX can also be installed and built on a native Windows system, but with - some potential tool-related issues (see the discussion "Native Windows - Build" under "Building NuttX" below). GNUWin32 is used to provide - compatible native windows tools. - -Installing Cygwin ------------------ - - Installing Cygwin on your Windows PC is simple, but time consuming. See - http://www.cygwin.com/ for installation instructions. Basically you just - need to download a tiny setup.exe program and it does the real, network - installation for you. - - Some Cygwin installation tips: - - 1. Install at C:\cygwin - - 2. Install EVERYTHING: "Only the minimal base packages from the - Cygwin distribution are installed by default. Clicking on categories - and packages in the setup.exe package installation screen will - provide you with the ability to control what is installed or updated. - Clicking on the "Default" field next to the "All" category will - provide you with the opportunity to install every Cygwin package. - Be advised that this will download and install hundreds of megabytes - to your computer." - - If you use the "default" installation, you will be missing many - of the Cygwin utilities that you will need to build NuttX. The - build will fail in numerous places because of missing packages. - - NOTE: The last time I installed EVERYTHING, the download was - about 5GiB. The server I selected was also very slow so it took - over a day to do the whole install! - - NOTE: You don't really have to install EVERYTHING but I cannot - answer the question "Then what should I install?" I don't know - the answer to that and so will continue to recommend installing - EVERYTHING. - - You should certainly be able to omit "Science", "Math", and - "Publishing". You can try omitting KDE, Gnome, GTK, and other - graphics packages if you don't plan to use them. - - Perhaps a minimum set would be those packages listed below for the - "Ubuntu Bash under Windows 10" installation? - - UPDATE: Sergey Frolov had success with the following minimal - Cygwin configuration: - - 1. After starting the Cygwin installer, keep the recommended - packages that are pre-selected in the default configuration. - 2. Using the installation tools, add the following packages: - - make (GNU make) bison libgmp3-dev - gcc-core byacc libmpfr-dev - gcc-g++ gperf libmpc-dev - flex gdb automake-1.15 - libncurses-dev libgmp-dev - - After installing Cygwin, you will get lots of links for installed - tools and shells. I use the RXVT native shell. It is fast and reliable - and does not require you to run the Cygwin X server (which is neither - fast nor reliable). Unless otherwise noted, the rest of these - instructions assume that you are at a bash command line prompt in - either Linux or in Cygwin shell. - -Using MSYS ----------- - - MSYS is an environment the derives from Cygwin. Thus, most things said - about Cygwin apply equally to MSYS. This section will, then, focus on - the differences when using MSYS, specifically MSYS2. - - Here is it assumed that you have already downloaded and installed MSYS2 - from https://www.msys2.org using the windows installer available at that - location. It is also assumed that you have brought in the necessary - tools using the 'pacman' package management tool Tools needed including: - - pacman -S git - pacman -S make - pacman -S gcc - pacman -S gdb - - And possibly others depending upon your usage. Then you will need to - build and install kconfig-frontends per the instructions of the top-level - README.txt file in the tools repository. This requires the following - additional tools: - - pacman -S bison - pacman -S gperf - pacman -S ncurses-devel - pacman -S automake-wrapper - pacman -S autoconf - pacman -S pkg-config - - Because of some versioning issues, I had to run 'aclocal' prior to - running the kconfig-frontends configure script. See "Configuring NuttX" - below for further information. - - Unlike Cygwin, MSYS does not support symbolic links. The 'ln -s' command - will, in fact, copy a directory! This means that you Make.defs file will - have to include definitions like: - - ifeq ($(CONFIG_WINDOWS_MSYS),y) - DIRLINK = $(TOPDIR)/tools/copydir.sh - DIRUNLINK = $(TOPDIR)/tools/unlink.sh - endif - - This will force the directory copies to work in a way that can be handled - by the NuttX build system. NOTE: The default link.sh script has been - updated so that is should now be MSYS2 compatible. The above is preferred - but no longer necessary in the Make.defs file. - - To build the simulator under MSYS, you also need: - - pacman -S zlib-devel - - It appears that you cannot use directory names with spaces in them like - "/c/Program\ Files \(86\)" in the MSYS path variable. I worked around this - by create Windows junctions like this:: - - 1. Open the a windows command terminal, - 2. CD to c:\msys64, then - 3. mklink /j programfiles "C:/Program\ Files" and - 4. mklink /j programfiles86 "C:/Program\ Files\ \(x86\)" - - They then show up as /programfiles and /programfiles86 with the MSYS2 - sandbox. Thos paths can then be used with the PATH variable. I had - to do something similar for the path to the GNU Tools "ARM Embedded - Toolchain" which also has spaces in the path name. - -Ubuntu Bash under Windows 10 ----------------------------- - - A better version of a command-line only Ubuntu under Windows 10 (beta) - has recently been made available from Microsoft. - - Installation - ------------ - Installation instructions abound on the Internet complete with screen - shots. I will attempt to duplicate those instructions in full here. - Here are the simplified installation steps: - - - Open "Settings". - - Click on "Update & security". - - Click on "For Developers". - - Under "Use developer features", select the "Developer mode" option to - setup the environment to install Bash. - - A message box should pop up. Click "Yes" to turn on developer mode. - - After the necessary components install, you'll need to restart your - computer. - - Once your computer reboots: - - - Open "Control Panel". - - Click on "Programs". - - Click on "Turn Windows features on or off". - - A list of features will pop up, check the "Windows Subsystem for Linux - (beta)" option. - - Click OK. - - Once the components installed on your computer, click the "Restart - now" button to complete the task. - - After your computer restarts, you will notice that Bash will not appear in - the "Recently added" list of apps, this is because Bash isn't actually - installed yet. Now that you have setup the necessary components, use the - following steps to complete the installation of Bash: - - - Open "Start", do a search for bash.exe, and press "Enter". - - On the command prompt, type y and press Enter to download and install - Bash from the Windows Store. This will take awhile. - - Then you'll need to create a default UNIX user account. This account - doesn't have to be the same as your Windows account. Enter the - username in the required field and press Enter (you can't use the - username "admin"). - - Close the "bash.exe" command prompt. - - Now that you completed the installation and setup, you can open the Bash - tool from the Start menu like you would with any other app. - - Accessing Windows Files from Ubuntu - ----------------------------------- - File systems will be mounted under "/mnt" so for example "C:\Program Files" - appears at "/mnt/c/Program Files". This is as opposed to Cygwin where - the same directory would appear at "/cygdrive/c/Program Files". - - With these differences (perhaps a few other Windows quirks) the Ubuntu - install works just like Ubuntu running natively on your PC. - - A good tip for file sharing is to use symbolic links within your Ubuntu - home directory. For example, suppose you have your "projects" directory - at C:\Documents\projects. Then you can set up a link to the projects/ - directory in your Ubuntu directory like: - - ln -s /mnt/c/Documents/projects projects - - Accessing Ubuntu Files From Windows - ----------------------------------- - In Ubuntu Userspace for Windows, the Ubuntu file system root directory is - at: - - %localappdata%\lxss\rootfs - - Or - - C:\Users\Username\AppData\Local\lxss\rootfs - - However, I am unable to see my files under the rootfs\home directory. - After some looking around, I find the home directory - %localappdata%\lxss\home. - - With that trick access to the /home directory, you should actually be - able to use Windows tools outside of the Ubuntu sandbox with versions of - NuttX built within the sandbox using that path. - - Executing Windows Tools from Ubuntu - ----------------------------------- - You can also execute Windows tools from within the Ubuntu sandbox: - - /mnt/c/Program\ Files\ \(x86\)/Microchip/xc32/v1.43/bin/xc32-gcc.exe --version - Unable to translate current working directory. Using C:\WINDOWS\System32 - xc32-gcc.exe (Microchip Technology) 4.8.3 MPLAB XC32 Compiler v1.43 Build date: Mar 1 2017 - ... - - The error message indicates that there are more issues: You cannot mix - Windows tools that use Windows style paths in an environment that uses - POSIX paths. I think you would have to use Linux tools only from within - the Ubuntu sandbox. - - Install Ubuntu Software - ----------------------- - Use "sudo apt-get install ". As examples, this is how - you would get GIT: - - sudo apt-get install git - - This will get you a compiler for your host PC: - - sudo apt-get install gcc - - This will get you an ARM compiler for your target: - - sudo apt-get install gcc-arm-none-eabi - - NOTE: That is just an example. I am not sure if apt-get will give you a - current or usable compiler. You should carefully select your toolchain - for the needs of your project. - - You will also need to get the kconfig-frontends configuration as - described below under "NuttX Configuration Tool". In order to build the - kconfig-frontends configuration tool you will also need: make, gperf, - flex, bison, and libncurses-dev. - - That is enough to do a basic NuttX build. - - Integrating with Windows Tools - ------------------------------ - If you want to integrate with Windows native tools, then you would need - deal with the same kind of craziness as with integrating Cygwin with - native toolchains, see the section "Cygwin Build Problems" below. - - However, there is currently no build support for using Windows native - tools with Ubuntu under Windows. This tool combination is made to work - with Cygwin through the use of the 'cygpath -w' tool that converts paths - from say '/cydrive/c/Program Files' to 'C:\Program Files'. There is, - however, no corresponding tool to convert '/mnt/c/Program Files' in the - Ubuntu environment. - - Graphics Support - ---------------- - The Ubuntu version support by Microsoft is a command-line only version. - There is no support for Linux graphics utilities. - - This limitation is not a limitation of Ubuntu, however, only in what - Microsoft is willing to support. If you install a X-Server, then you - can also use basic graphics utilities. See for example: - - http://www.howtogeek.com/261575/how-to-run-graphical-linux-desktop-applications-from-windows-10s-bash-shell/ - - Many Linux graphics programs would, however, also require a graphics - framework like GTK or Qt. So this might be a trip down the rabbit hole. - -INSTALLATION -^^^^^^^^^^^^ - - There are two ways to get NuttX: You may download released, stable - tarballs from either the Bitbucket or Sourceforge download locations. - Or you may get NuttX by cloning the Bitbucket GIT repositories. Let's - consider the released tarballs first: - -Download and Unpack -------------------- - - Download and unpack the NuttX tarball. If you are reading this, then - you have probably already done that. After unpacking, you will end - up with a directory called nuttx-version (where version is the NuttX - version number). You might want to rename that directory nuttx to - match the various instructions in the documentation and some scripts - in the source tree. - - Download locations: - - https://bitbucket.org/nuttx/nuttx/downloads - https://sourceforge.net/projects/nuttx/files/nuttx/ - -Semi-Optional apps/ Package ---------------------------- - - All NuttX libraries and example code used to be in included within - the NuttX source tree. As of NuttX-6.0, this application code was - moved into a separate tarball, the apps tarball. If you are just - beginning with NuttX, then you will want to download the versioned - apps tarball along with the NuttX tarball. If you already have your - own product application directory, then you may not need the apps - tarball. - - It is called "Semi-optional" because if you don't have some apps/ - directory, NuttX will *fail* to build! You do not necessarily need - to use the NuttX apps tarball but may, instead, provide your own - custom application directory. Such a custom directory would need - to include a valid Makefile to support the build and a valid Kconfig - file to support the configuration. More about these files later. - - Download then unpack the apps tarball in the same directory where you - unpacked the NuttX tarball. After you unpack the apps tarball, you - will have a new directory called apps-version (where the version - should exactly match the version of the NuttX tarball). Again, you - might want to rename the directory to simply apps/ to match what - you read in the documentation - - After unpacking (and renaming) the apps tarball, you will have two - directories side by side like this: - - | - +----+----+ - | | - nuttx/ apps/ - - This is important because the NuttX build will expect to find the - apps directory in that (default) location. That default location - can be changed by modifying your NuttX configuration file, but that - is another story. - -Installation Directories with Spaces in the Path ------------------------------------------------- - - The nuttx build directory should reside in a path that contains no - spaces in any higher level directory name. For example, under - Cygwin, your home directory might be formed from your first and last - names like: "/home/First Last". That will cause strange errors when - the make system tries to build. - - [Actually, that problem is probably not too difficult to fix. Some - Makefiles probably just need some paths within double quotes] - - I work around spaces in the home directory name, by creating a - new directory that does not contain any spaces, such as /home/nuttx. - Then I install NuttX in /home/nuttx and always build from - /home/nuttx/nuttx-code. - -Downloading from Repositories ------------------------------ - - Cloning the Repository - - BEFORE cloning repositories on any Windows platform do the following GIT - command: - - git config --global core.autocrlf false - - That will avoid conversions of linefeeds (newlines, \n) to carriage - return plus linefeed sequences (\r\n) - - The current NuttX du jour is available in from a GIT repository. Here are - instructions for cloning the core NuttX RTOS (corresponding to the nuttx - tarball discussed above):: - - git clone https://bitbucket.org/nuttx/nuttx.git nuttx - - And the semi-optional apps/ application directory and be cloned like: - - git clone https://bitbucket.org/nuttx/apps.git apps - - That will give you the same directory structure like this: - - | - +----+----+ - | | - nuttx/ apps/ - - Configuring the Clones - - The following steps need to be performed for each of the repositories. - After changing to the clone directory: - - Set your identity: - - git config --global user.name "My Name" - git config --global user.email my.name@example.com - - Colorized diffs are much easier to read: - - git config --global color.branch auto - git config --global color.diff auto - git config --global color.interactive auto - git config --global color.status auto - - Checkout other settings - - git config --list - - Cloning NuttX Inside Cygwin - - If you are cloning the NuttX repository, it is recommended to avoid - automatic end of lines conversions by git. These conversions may break - some scripts like configure.sh. Before cloning, do the following: - - git config --global core.autocrlf false - -Related Repositories --------------------- - - These are standalone repositories: - - * https://bitbucket.org/nuttx/apps - - This directory holds an optional package of applications and libraries - can be used with the NuttX RTOS. There is a README.txt file there that - will provide more information about that package. - - * https://bitbucket.org/nuttx/nxwidgets - - This is the NuttX C++ graphics support. This includes NxWM, the tiny - NuttX Window Manager. - - * https://bitbucket.org/nuttx/uclibc - - This repository contains a version of the uClibc++ C++ library. This code - originates from http://cxx.uclibc.org/ and has been adapted for NuttX by the - RGMP team (http://rgmp.sourceforge.net/wiki/index.php/Main_Page). - - * https://bitbucket.org/nuttx/buildroot - - A environment that you can to use to build a custom, NuttX GNU toolchain. - - * https://bitbucket.org/nuttx/tools - - There are snapshots of some tools here that you will need to work with - NuttX: kconfig-frontends, genromfs, and others. - - * https://bitbucket.org/nuttx/pascal - - Yes, this really is a Pascal compiler. The Pascal p-code run-time and - pcode debugger can be built as a part of NuttX. - -Notes about Header Files ------------------------- - - Other C-Library Header Files. - - When a GCC toolchain is built, it must be built against a C library. - The compiler together with the contents of the C library completes the - C language definition and provides the complete C development - environment. NuttX provides its own, built-in C library. So the - complete, consistent C language definition for use with NuttX comes from - the combination of the compiler and the header files provided by the - NuttX C library. - - When a GCC toolchain is built, it incorporates the C library header - files into the compiler internal directories and, in this way, the C - library really becomes a part of the toolchain. If you use the NuttX - buildroot toolchain as described below under "NuttX Buildroot - Toolchain", your GCC toolchain will build against the NuttX C library - and will incorporate the NuttX C library header files as part of the - toolchain. - - If you use some other, third-party tool chain, this will not be the - case, however. Those toolchains were probably built against some - other, incompatible C library distribution (such as newlib). Those - tools will have incorporated the incompatible C library header files - as part of the toolchain. These incompatible header files must *not* - be used with NuttX because they will conflict with definitions in the - NuttX built-in C-Library. For such toolchains that include header - files from a foreign C-Library, NuttX must be compiled without using - the standard header files that are distributed with your toolchain. - This prevents including conflicting, incompatible header files such - as stdio.h. - - The math.h and stdarg.h are probably the two most trouble some header - files to deal with. These troublesome header files are discussed in - more detail below. - - Header Files Provided by Your Toolchain. - - Certain header files, such as setjmp.h, stdarg.h, and math.h, may still - be needed from your toolchain and your compiler may not, however, be able - to find these if you compile NuttX without using standard header files - (i.e., with -nostdinc). If that is the case, one solution is to copy - those header file from your toolchain into the NuttX include directory. - - Duplicated Header Files. - - There are also a few header files that can be found in the nuttx/include - directory which are duplicated by the header files from your toolchain. - stdint.h and stdbool.h are examples. If you prefer to use the stdint.h - and stdbool.h header files from your toolchain, those could be copied - into the nuttx/include/ directory. Using most other header files from - your toolchain would probably cause errors. - - math.h - - Even though you should not use a foreign C-Library, you may still need - to use other, external libraries with NuttX. In particular, you may - need to use the math library, libm.a. NuttX supports a generic, built-in - math library that can be enabled using CONFIG_LIBM=y. However, you may - still want to use a higher performance external math library that has - been tuned for your CPU. Sometimes such tuned math libraries are - bundled with your toolchain. - - The math library header file, math.h, is a then special case. If you do - nothing, the standard math.h header file that is provided with your - toolchain will be used. - - If you have a custom, architecture specific math.h header file, then - that header file should be placed at arch//include/math.h. There - is a stub math.h header file located at include/nuttx/lib/math.h. This stub - header file can be used to "redirect" the inclusion to an architecture- - specific math.h header file. If you add an architecture specific math.h - header file then you should also define CONFIG_ARCH_MATH_H=y in your - NuttX Configuration file. If CONFIG_ARCH_MATH_H is selected, then the - top-level Makefile will copy the stub math.h header file from - include/nuttx/lib/math.h to include/math.h where it will become the system - math.h header file. The stub math.h header file does nothing other - than to include that architecture-specific math.h header file as the - system math.h header file. - - float.h - - If you enable the generic, built-in math library, then that math library - will expect your toolchain to provide the standard float.h header file. - The float.h header file defines the properties of your floating point - implementation. It would always be best to use your toolchain's float.h - header file but if none is available, a default float.h header file will - be provided if this option is selected. However, there is no assurance - that the settings in this float.h are actually correct for your platform! - - stdarg.h - - In most cases, the correct version of stdarg.h is the version provided - with your toolchain. However, sometimes there are issues with - using your toolchains stdarg.h. For example, it may attempt to draw in - header files that do not exist in NuttX or perhaps the header files that - it uses are not compatible with the NuttX header files. In those cases, - you can use an architecture-specific stdarg.h header file by defining - CONFIG_ARCH_STDARG_H=y. - - See the discussion above for the math.h header. This setting works - exactly the same for the stdarg.h header file. - -CONFIGURING NUTTX -^^^^^^^^^^^^^^^^^ - -Instantiating "Canned" Configurations -------------------------------------- - - configure.sh and configure.bat: - - "Canned" NuttX configuration files are retained in: - - boards////configs/ - - Where is the name of your development board and - is the name of the sub-directory containing a specific configuration for - that board. and refer to characteristics of the - MCU used on the board: is the CPU architecture implemented - by the MCU; identifies the MCU chip family. Only a few - steps are required to instantiate a NuttX configuration, but to make the - configuration even easier there are scripts available in the tools/ - sub-directory combines those simple steps into one command. - - There is one tool for use with any Bash-like shell that does configuration - steps. It is used as follows: - - tools/configure.sh : - - There is an alternative Windows batch file that can be used in the windows - native environment like: - - tools\configure.bat : - - And, to make sure that other platforms are supported, there is also a - C program at tools/configure.c that can be compiled to establish the - board configuration. - - See tools/README.txt for more information about these scripts. - - General information about configuring NuttX can be found in: - - {TOPDIR}/boards/README.txt - {TOPDIR}/boards////README.txt - - The Hidden Configuration Scripts: - - As mentioned above, there are only a few simple steps to instantiating a - NuttX configuration. Those steps are hidden by the configuration scripts - but are summarized below: - - 1. Copy Files - - Configuring NuttX requires only copying two files from the - to the directory where you installed NuttX (TOPDIR): - - Copy boards////configs//Make.def - to {TOPDIR}/Make.defs - - OR - - Copy boards////scripts/Make.def - to {TOPDIR}/Make.defs - - Make.defs describes the rules needed by your tool chain to compile - and link code. You may need to modify this file to match the - specific needs of your toolchain. NOTE that a configuration may - have its own unique Make.defs file in its configuration directory or - it may use a common Make.defs file for the board in the scripts/ - directory. The first takes precedence. - - Copy boards////configs//defconfig - to{TOPDIR}/.config - - The defconfig file holds the actual build configuration. This - file is included by all other make files to determine what is - included in the build and what is not. This file is also used - to generate a C configuration header at include/nuttx/config.h. - - Copy other, environment-specific files to{TOPDIR} - - This might include files like .gdbinit or IDE configuration files - like .project or .cproject. - - 2. Refresh the Configuration - - New configuration setting may be added or removed. Existing settings - may also change there values or options. This must be handled by - refreshing the configuration as described below. - - NOTE: NuttX uses only compressed defconfig files. For the NuttX - defconfig files, this refreshing step is *NOT* optional; it is also - necessary to uncompress and regenerate the full making file. This is - discussed further below. - -Refreshing Configurations -------------------------- - - Configurations can get out of date. As new configuration settings are - added or removed or as dependencies between configuration settings - change, the contents of a default configuration can become out of synch - with the build systems. Hence, it is a good practice to "refresh" each - configuration after configuring and before making. To refresh the - configuration, use the NuttX Configuration Tool like this: - - make oldconfig - - AFTER you have instantiated the NuttX configuration as described above. - The configuration step copied the .config file into place in the top-level - NuttX directory; 'make oldconfig' step will then operate on that .config - file to bring it up-to-date. - - If your configuration is out of date, you will be prompted by 'make oldconfig' - to resolve the issues detected by the configuration tool, that is, to - provide values for the new configuration options in the build system. Doing - this can save you a lot of problems down the road due to obsolete settings in - the default board configuration file. The NuttX configuration tool is - discussed in more detail in the following paragraph. - - Confused about what the correct value for a new configuration item should - be? Enter ? in response to the 'make oldconfig' prompt and it will show - you the help text that goes with the option. - - If you don't want to make any decisions are willing to just accept the - recommended default value for each new configuration item, an even easier - way is: - - make olddefconfig - - The olddefconfig target will simply bring your configuration up to date with - the current Kconfig files, setting any new options to the default value. - No questions asked. - -NuttX Configuration Tool ------------------------- - - An automated tool has been incorporated to support re-configuration - of NuttX. This tool is based on the kconfig-frontends application available - at https://bitbucket.org/nuttx/tools/src/master/kconfig-frontends/. (This - is a snapshot of http://ymorin.is-a-geek.org/projects/kconfig-frontends.) - This application provides a tool called 'kconfig-mconf' that is used by the - NuttX top-level Makefile. The following make target is provided: - - make menuconfig - - This make target will bring up NuttX configuration menus. - - WARNING: Never do 'make menuconfig' on a configuration that has - not been converted to use the kconfig-frontends tools! This will - damage your configuration (see - http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig). - - How do we tell a new configuration from an old one? See "Incompatibilities - with Older Configurations" below. - - The 'menuconfig' make target depends on two things: - - 1. The Kconfig configuration data files that appear in almost all - NuttX directories. These data files are the part that is still - under development (patches are welcome!). The Kconfig files - contain configuration information for the configuration settings - relevant to the directory in which the Kconfig file resides. - - NOTE: For a description of the syntax of this configuration file, - see kconfig-language.txt in the tools repository at - https://bitbucket.org/nuttx/tools - - 2. The 'kconfig-mconf' tool. 'kconfig-mconf' is part of the - kconfig-frontends package. You can download that package from the - snapshot in the tools repository at https://bitbucket.org/nuttx/tools. - - Building kconfig-frontends under Linux may be as simple as - 'configure; make; make install' but there may be some build - complexities, especially if you are building under Cygwin. See - the more detailed build instructions in the top-level README.txt - file of the tools repository at https://bitbucket.org/nuttx/tools. - - The 'make install' step will, by default, install the 'kconfig-mconf' - tool at /usr/local/bin/mconf. Where ever you choose to - install 'kconfig-mconf', make certain that your PATH variable includes - a path to that installation directory. - - The kconfig-frontends tools will not build in a native Windows - environment directly "out-of-the-box". For the Windows native - case, you should use the modified version of kconfig-frontends - that can be found at - http://uvc.de/posts/linux-kernel-configuration-tool-mconf-under-windows.html - - The basic configuration order is "bottom-up": - - - Select the build environment, - - Select the processor, - - Select the board, - - Select the supported peripherals - - Configure the device drivers, - - Configure the application options on top of this. - - This is pretty straight forward for creating new configurations - but may be less intuitive for modifying existing configurations. - - Another ncurses-based tool that is an option to kconfig-mconf is - kconfig-nconf. The differences are primary in in the aesthetics of the - UI. If you have kconfig-nconf built, then you can invoke that front end - with: - - make nconfig - - If you have an environment that supports the Qt or GTK graphical systems - (probably KDE or gnome, respectively, or Cygwin under Windows with Qt or - GTK installed), then you can also build the graphical kconfig-frontends, - kconfig-qconf and kconfig-gconf. In these case, you can start the - graphical configurator with either: - - make qconfig - - or - - make gconfig - - Some keyboard shortcuts supported by kconfig-mconf, the tool that runs - when you do 'make menuconfig': - - - '?' will bring up the mconfig help display. - - - '/' can be used find configuration selections. - - - 'Z' can be used to reveal hidden configuration options - - These last two shortcuts are described further in the following - paragraphs. - -Finding Selections in the Configuration Menus ---------------------------------------------- - - The NuttX configuration options have gotten complex and it can be very - difficult to find options in the menu trees if you are not sure where - to look. The "basic configuration order" describe above can help to - narrow things down. - - But if you know exactly what configuration setting you want to select, - say CONFIG_XYZ, but not where to find it, then the 'make menuconfig' - version of the tool offers some help: By pressing the '/' key, the - tool will bring up a menu that will allow you to search for a - configuration item. Just enter the string CONFIG_XYZ and press 'ENTER'. - It will show you not only where to find the configuration item, but - also all of the dependencies related to the configuration item. - -Reveal Hidden Configuration Options ------------------------------------ - - If you type 'Z', then kconfig-mconf will change what is displayed. - Normally, only enabled features that have all of their dependencies met - are displayed. That is, of course, not very useful if you would like to - discover new options or if you are looking for an option and do not - realize that the dependencies have not yet been selected and, hence, it - is not displayed. - - But if you enter 'Z', then every option will be shown, whether or not its - dependencies have been met. You can then see everything that could be - selected with the right dependency selections. These additional options - will be shown the '-' for the selection and for the value (since it - cannot be selected and has no value). About all you do is to select - the option to see what the dependencies are. - -Make Sure that You are on the Right Platform --------------------------------------------- - - Saved configurations may run on Linux, Cygwin (32- or 64-bit), or other - platforms. The platform characteristics can be changed use 'make - menuconfig'. Sometimes this can be confusing due to the differences - between the platforms. Enter sethost.sh - - sethost.sh is a simple script that changes a configuration to your - host platform. This can greatly simplify life if you use many different - configurations. For example, if you are running on Linux and you - configure like this: - - tools/configure.sh board:configuration - - The you can use the following command to both (1) make sure that the - configuration is up to date, AND (2) the configuration is set up - correctly for Linux: - - tools/sethost.sh -l - - Or, if you are on a Windows/Cygwin 64-bit platform: - - tools/sethost.sh -c - - Or, for MSYS/MSYS2: - - tools/sethost.sh -g - - Other options are available from the help option built into the - script. You can see all options with: - - tools/sethost.sh -h - - Recently, the options to the configure.sh (and configure.bat) scripts have - been extended so that you both setup the configuration, select for the host - platform that you use, and uncompress and refresh the defconfig file all in - one command like: - - tools/configure.sh -l board:configuration - - For a Linux host or for a Windows/Cygwin host: - - tools/configure.sh -h board:configuration - - Other options are available from the help option built into the - script. You can see all options with: - - tools/configure.sh -h - -Comparing Two Configurations ----------------------------- - - If you try to compare two configurations using 'diff', you will probably - not be happy with the result. There are superfluous things added to - the configuration files that make comparisons with the human eye - difficult. - - There is a tool at nuttx/tools/cmpconfig.c that can be built to simplify - these comparisons. The output from this difference tool will show only - the meaningful differences between two configuration files. This tool is - built as follows: - - cd nuttx/tools - make -f Makefile.host - - This will create a program called 'cmpconfig' or 'comconfig.exe' on Windows. - - Why would you want to compare two configuration files? Here are a few - of the reasons why I do this - - 1. When I create a new configuration I usually base it on an older - configuration and I want to know, "What are the options that I need to - change to add the new feature to the older configurations?" For example, - suppose that I have a boardA/nsh configuration and I want to create a - boardA/nxwm configuration. Suppose I already have boardB/nsh and - boardB/nxwm configurations. Then by comparing the boardB/nsh with the - boardB/nxwm I can see the modifications that I would need to make to my - boardA/nsh to create a new boardA/nxwm. - - 2. But the most common reason that I use the 'cmpconfig' program is to - check the results of "refreshing" a configuration with 'make oldconfig' - (see the paragraph "Refreshing Configurations" above). The 'make - oldconfig' command will make changes to my configuration and using - 'cmpconfig', I can see precisely what those changes were and if any - should be of concern to me. - - 3. The 'cmpconfig' tool can also be useful when converting older, legacy - manual configurations to the current configurations based on the - kconfig-frontends tools. See the following paragraph. - -Making defconfig Files ----------------------- - - .config Files as defconfig Files: - - The minimum defconfig file is simply the generated .config file with - CONFIG_APPS_DIR setting removed or commented out. That setting provides - the name and location of the apps/ directory relative to the nuttx build - directory. The default is ../apps/, however, the apps directory may be - any other location and may have a different name. For example, the name - of versioned NuttX releases are always in the form apps-xx.yy where xx.yy - is the version number. - - Finding the apps/ Directory Path: - - When the default configuration is installed using one of the scripts or - programs in the NuttX tools directory, there will be an option to provide - the path to the apps/ directory. If not provided, then the configure tool - will look around and try to make a reasonable decision about where the - apps/ directory is located. - - Compressed defconfig Files: - - The Makefile also supports an option to generate very small defconfig - files. The .config files are quite large and complex. But most of the - settings in the .config file simply have the default settings from the - Kconfig files. These .config files can be converted into small defconfig - file: - - make savedefconfig - - That make target will generate a defconfig file in the top-level - directory. The size reduction is really quite remarkable: - - wc -l .config defconfig - 1085 .config - 82 defconfig - 1167 total - - In order to be usable, the .config file installed from the compressed - defconfig file must be reconstituted using: - - make olddefconfig - - NOTE 1: Only compressed defconfig files are retained in the NuttX repository. - All patches and PRs that attempt to add or modify a defconfig file MUST - use the compressed defconfig format as created by 'make savdefconfig.' - - NOTE 2: When 'make savedefconfig' runs it will try several things some of - which are expected to fail. In these cases you will see an error message - from make followed by "(ignored)." You should also ignore these messages - - CAUTION: This size reduction was accomplished by removing all setting - from the .config file that were at the default value. 'make olddefconfig' - can regenerate the original .config file by simply restoring those default - settings. The underlying assumption here is, of course, that the default - settings do not change. If the default settings change, and they often - do, then the original .config may not be reproducible. - - So if your project requires 100% reproducibility over a long period of - time, you make want to save the complete .config files vs. the standard, - compressed defconfig file. - - Configuring with "Compressed" defconfig Files: - - As described above defconfig, all NuttX defconfig files are compressed - using 'make savedeconfig'. These compressed defconfig files are - generally not fully usable as they are and may not build the target - binaries that you want because the compression process removed all of - the default settings from the defconfig file. To restore the default - settings, you should run the following after configuring: - - make olddefconfig - - That will restore the the missing defaulted values. - - Using this command after configuring is generally a good practice anyway: - Even if the defconfig files are not "compressed" in this fashion, the - defconfig file may be old and the only way to assure that the installed - .config is is up to date is via 'make oldconfig' or 'make olddefconfig'. - See the paragraph above entitled ""Refreshing Configurations" for - additional information. - -Incompatibilities with Older Configurations -------------------------------------------- - - ***** WARNING ***** - - The current NuttX build system supports *only* the new compressed, - defconfig configuration files generated using the kconfig-frontends tools - as described in the preceding section. Support for the older, legacy, - manual configurations was eliminated in NuttX 7.0; support for - uncompressed .config-files-as-defconfig files was eliminated after - NuttX-7.21. All configurations must now be done using the - kconfig-frontends tool. The older manual configurations and the new - kconfig-frontends configurations are not compatible. Old legacy - configurations can *not* be used with the kconfig-frontends tool and, - hence, cannot be used with releases of NuttX 7.0 and beyond: - - If you run 'make menuconfig' with a legacy configuration the resulting - configuration will probably not be functional. - - Q: How can I tell if a configuration is a new kconfig-frontends - configuration or an older, manual configuration? - - A: Only old, manual configurations will have an appconfig file - - - Q: How can I convert a older, manual configuration into a new, - kconfig-frontends toolchain. - - A: Refer to http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig - - ***** WARNING ***** - - As described above, whenever you use a configuration, you really should - always refresh the configuration with the following command *before* you - make NuttX: - - make oldconfig - - OR - - make olddefconfig - - This will make sure that the configuration is up-to-date in the event that - it has lapsed behind the current NuttX development (see the paragraph - "Refreshing Configurations" above). But this only works with *new* - configuration files created with the kconfig-frontends tools. - - Further, this step is *NOT* optional with the new, compressed defconfig - files. It is a necessary step that will also uncompress the defconfig - file, regenerating the .config and making it usable for NuttX builds. - - Never do 'make oldconfig' (OR 'make menuconfig') on a configuration that - has not been converted to use the kconfig-frontends tools! This will - damage your configuration (see - http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig). - -NuttX Configuration Tool under DOS ----------------------------------- - - Recent versions of NuttX support building NuttX from a native Windows - console window (see "Native Windows Build" below). But kconfig-frontends - is a Linux tool. At one time this was a problem for Windows users, but - now there is a specially modified version of the kconfig-frontends tools - that can be used: - http://uvc.de/posts/linux-kernel-configuration-tool-mconf-under-windows.html - - The configuration steps most recent versions of NuttX require the - kconfig-tweak tool that is not not available in the the above. However, - there has been an update to this Kconfig Windows tools that does include - kconfig-tweak: http://reclonelabs.com/more-kconfig-awesomeness-for-windows/ - - Source code is available here: https://github.com/reclone/kconfig-frontends-win32 - and https://github.com/reclone/kconfig-frontends-win32/releases - - It is also possible to use the version of kconfig-frontends built - under Cygwin outside of the Cygwin "sandbox" in a native Windows - environment: - - 1. You can run the configuration tool using Cygwin. However, the - Cygwin Makefile.win will complain so to do this will, you have - to manually edit the .config file: - - a. Delete the line: CONFIG_WINDOWS_NATIVE=y - b. Change the apps/ directory path, CONFIG_APPS_DIR to use Unix - style delimiters. For example, change "..\apps" to "../apps" - - And of course, after you use the configuration tool you need to - restore CONFIG_WINDOWS_NATIVE=y and the correct CONFIG_APPS_DIR. - - 2) You can, with some effort, run the Cygwin kconfig-mconf tool - directly in the Windows console window. In this case, you do not - have to modify the .config file, but there are other complexities: - - a. You need to temporarily set the Cygwin directories in the PATH - variable then run kconfig-mconf manually like: - - kconfig-mconf Kconfig - - There is a Windows batch file at tools/kconfig.bat that automates - these steps: - - tools/kconfig menuconfig - - b. There is an issue with accessing DOS environment variables from - the Cygwin kconfig-mconf running in the Windows console. The - following change to the top-level Kconfig file seems to work - around these problems: - - config APPSDIR - string - - option env="APPSDIR" - + default "../apps" - -TOOLCHAINS -^^^^^^^^^^ - -Cross-Development Toolchains ----------------------------- - - In order to build NuttX for your board, you will have to obtain a cross- - compiler to generate code for your target CPU. For each board, - configuration, there is a README.txt file (at - boards////README.txt). - That README file contains suggestions and information about appropriate - tools and development environments for use with your board. - - In any case, the PATH environment variable will need to be updated to - include the location where the build can find the toolchain binaries. - -NuttX Buildroot Toolchain -------------------------- - - For many configurations, a DIY set of tools is available for NuttX. These - tools can be downloaded from the NuttX Bitbucket.org file repository. After - unpacking the buildroot tarball, you can find instructions for building - the tools in the buildroot/boards/README.txt file. - - Check the README.txt file in the configuration directory for your board - to see if you can use the buildroot toolchain with your board (this - README.txt file is located in - boards////README.txt). - - This toolchain is available for both the Linux and Cygwin development - environments. - - Advantages: (1) NuttX header files are built into the tool chain, - and (2) related support tools like NXFLAT tools, the ROMFS - genromfs tools, and the kconfig-frontends tools can be built into your - toolchain. - - Disadvantages: This tool chain is not was well supported as some other - toolchains. GNU tools are not my priority and so the buildroot tools - often get behind. For example, until recently there was no EABI support - in the NuttX buildroot toolchain for ARM. - - NOTE: For Cortex-M3/4, there are OABI and EABI versions of the buildroot - toolchains. If you are using the older OABI toolchain the prefix for - the tools will be arm-nuttx-elf-; for the EABI toolchain the prefix will - be arm-nuttx-eabi-. If you are using the older OABI toolchain with - an ARM Cortex-M3/4, you will need to set CONFIG_ARMV7M_OABI_TOOLCHAIN - in the .config file in order to pick the right tool prefix. - - If the make system ever picks the wrong prefix for your toolchain, you - can always specify the prefix on the command to override the default - like: - - make CROSSDEV=arm-nuttx-elf - -SHELLS -^^^^^^ - - The NuttX build relies on some shell scripts. Some are inline in the - Makefiles and many are executable scripts in the tools/. directory. The - scripts were all developed using bash and many contain bash shell - dependencies. - - Most of the scripts begin with #!/bin/bash to specifically select the - bash shell. Some still have #!/bin/sh but I haven't heard any complaints - so these must not have bash dependencies. - - There are two shell issues that I have heard of: - - 1. Linux where /bin/sh refers to an incompatible shell (like ksh or csh). - - In this case, bash is probably available and the #!/bin/bash at the - beginning of the file should do the job. If any scripts with #!/bin/sh - fail, try changing that to #!/bin/bash and let me know about the change. - - 2. FreeBSD with the Bourne Shell and no bash shell. - - The other, reverse case has also been reported on FreeBSD setups that - have the Bourne shell, but not bash. In this base, #!/bin/bash fails - but #!/bin/sh works okay. My recommendation in this case is to create - a symbolic link at /bin/bash that refers to the Bourne shell. - - There may still be issues, however, with certain the bash-centric scripts - that will require modifications. - -BUILDING NUTTX -^^^^^^^^^^^^^^ - -Building --------- - - NuttX builds in-place in the source tree. You do not need to create - any special build directories. Assuming that your Make.defs is setup - properly for your tool chain and that PATH environment variable contains - the path to where your cross-development tools are installed, the - following steps are all that are required to build NuttX: - - cd{TOPDIR} - make - - At least one configuration (eagle100) requires additional command line - arguments on the make command. Read - {TOPDIR}/boards////README.txt to see - if that applies to your target. - -Re-building ------------ - - Re-building is normally simple -- just type make again. - - But there are some things that can "get you" when you use the Cygwin - development environment with Windows native tools. The native Windows - tools do not understand Cygwin's symbolic links, so the NuttX make system - does something weird: It copies the configuration directories instead of - linking to them (it could, perhaps, use the NTFS 'mklink' command, but it - doesn't). - - A consequence of this is that you can easily get confused when you edit - a file in one of the linked (i.e., copied) directories, re-build NuttX, - and then not see your changes when you run the program. That is because - build is still using the version of the file in the copied directory, not - your modified file! - - Older versions of NuttX did not support dependencies in this - configuration. So a simple work around this annoying behavior in this - case was the following when you re-build: - - make clean_context all - - This 'make' command will remove of the copied directories, re-copy them, - then make NuttX. - - However, more recent versions of NuttX do support dependencies for the - Cygwin build. As a result, the above command will cause everything to be - rebuilt (because it removes and will cause recreating the - include/nuttx/config.h header file). A much less gracefully but still - effective command in this case is the following for the ARM configuration: - - rm -rf arch/arm/src/chip arch/arm/src/board - - This "kludge" simple removes the copied directories. These directories - will be re-created when you do a normal 'make' and your edits will then be - effective. - -Build Targets and Options -------------------------- - - Build Targets: - Below is a summary of the build targets available in the top-level - NuttX Makefile: - - all - - The default target builds the NuttX executable in the selected output - formats. - - clean - - Removes derived object files, archives, executables, and temporary - files, but retains the configuration and context files and directories. - - distclean - - Does 'clean' then also removes all configuration and context files. - This essentially restores the directory structure to its original, - unconfigured stated. - - Application housekeeping targets. The APPDIR variable refers to the user - application directory. A sample apps/ directory is included with NuttX, - however, this is not treated as part of NuttX and may be replaced with a - different application directory. For the most part, the application - directory is treated like any other build directory in the Makefile script. - However, as a convenience, the following targets are included to support - housekeeping functions in the user application directory from the NuttX - build directory. - - apps_clean - - Perform the clean operation only in the user application directory - - apps_distclean - - Perform the distclean operation only in the user application directory. - The apps/.config file is preserved so that this is not a "full" distclean - but more of a configuration "reset" for the application directory. - - export - - The export target will package the NuttX libraries and header files into - an exportable package. Caveats: (1) These needs some extension for the KERNEL - build. (2) The logic in tools/mkexport.sh only supports GCC and, for example, - explicitly assumes that the archiver is 'ar' - - download - - This is a helper target that will rebuild NuttX and download it to the target - system in one step. The operation of this target depends completely upon - implementation of the DOWNLOAD command in the user Make.defs file. It will - generate an error an error if the DOWNLOAD command is not defined. - - The following targets are used internally by the make logic but can be invoked - from the command under certain conditions if necessary. - - depend - - Create build dependencies. (NOTE: There is currently no support for build - dependencies under Cygwin using Windows-native toolchains.) - - context - - The context target is invoked on each target build to assure that NuttX is - properly configured. The basic configuration steps include creation of the - the config.h and version.h header files in the include/nuttx directory and - the establishment of symbolic links to configured directories. - - clean_context - - This is part of the distclean target. It removes all of the header files - and symbolic links created by the context target. - - Build Options: - Of course, the value any make variable an be overridden from the make command - line. However, there is one particular variable assignment option that may - be useful to you: - - V=1 - - This is the build "verbosity flag." If you specify V=1 on the make command - line, you will see the exact commands used in the build. This can be very - useful when adding new boards or tracking down compile time errors and - warnings (Contributed by Richard Cochran). - -Native Windows Build --------------------- - - The beginnings of a Windows native build are in place but still not often - used as of this writing. The build was functional but because of lack of - use may find some issues to be resolved with this build configuration. - - The windows native build logic initiated if CONFIG_WINDOWS_NATIVE=y is - defined in the NuttX configuration file: - - This build: - - - Uses all Windows style paths - - Uses primarily Windows batch commands from cmd.exe, with - - A few extensions from GNUWin32 - - In this build, you cannot use a Cygwin or MSYS shell. Rather the build must - be performed in a Windows console window. Here is a better terminal than the - standard issue, CMD.exe terminal: ConEmu which can be downloaded from: - https://sourceforge.net/projects/conemu/ or https://conemu.github.io/ . - - Build Tools. The build still relies on some Unix-like commands. I use - the GNUWin32 tools that can be downloaded from http://gnuwin32.sourceforge.net/ - using the 'Download all' selection. Individual packages can be download - instead if you know what you are doing and want a faster download (No, I - can't tell you which packages you should or should not download). - - Host Compiler: I use the MingGW GCC compiler which can be downloaded from - http://www.mingw.org/. If you are using GNUWin32, then it is recommended - the you not install the optional MSYS components as there may be conflicts. - - This capability should still be considered a work in progress because: - - (1) It has not been verified on all targets and tools, and - (2) it still lacks some of the creature-comforts of the more mature - environments. - -Installing GNUWin32 -------------------- - - The Windows native build will depend upon a few Unix-like tools that can be - provided either by MSYS or GNUWin32. The GNUWin32 are available from - http://gnuwin32.sourceforge.net/. GNUWin32 provides ports of tools with a - GPL or similar open source license to modern MS-Windows (Microsoft Windows - 2000 / XP / 2003 / Vista / 2008 / 7). See - http://gnuwin32.sourceforge.net/packages.html for a list of all of the tools - available in the GNUWin32 package. - - The SourceForge project is located here: - http://sourceforge.net/projects/gnuwin32/. The project is still being - actively supported (although some of the Windows ports have gotten very old). - - Some commercial toolchains include a subset of the GNUWin32 tools in the - installation. My recommendation is that you download the GNUWin32 tools - directly from the sourceforge.net website so that you will know what you are - using and can reproduce your build environment. - - GNUWin32 Installation Steps: - - The following steps will download and execute the GNUWin32 installer. - - 1. Download GetGNUWin32-x.x.x.exe from - http://sourceforge.net/projects/getgnuwin32/files/. This is the - installer. The current version as of this writing is 0.6.3. - - 2. Run the installer. - - 3. Accept the license. - - 4. Select the installation directory. My recommendation is the - directory that contains this README file (). - - 5. After running GetGNUWin32-0.x.x.exe, you will have a new directory - /GetGNUWin32 - - Note that the GNUWin32 installer didn't install GNUWin32. Instead, it - installed another, smarter downloader. That downloader is the GNUWin32 - package management tool developed by the Open SSL project. - - The following steps probably should be performed from inside a DOS shell. - - 6. Change to the directory created by GetGNUWin32-x.x.x.exe - - cd GetGNUWin32 - - 7. Execute the download.bat script. The download.bat script will download - about 446 packages! Enough to have a very complete Linux-like environment - under the DOS shell. This will take awhile. This step only downloads - the packages and the next step will install the packages. - - download - - 8. This step will install the downloaded packages. The argument of the - install.bat script is the installation location. C:\gnuwin32 is the - standard install location: - - install C:\gnuwin32 - - NOTE: This installation step will install *all* GNUWin32 packages... far - more than you will ever need. If disc space is a problem for you, you might - need to perform a manual installation of the individual ZIP files that you - will find in the /GetGNUWin32/packages directory. - -CYGWIN BUILD PROBLEMS -^^^^^^^^^^^^^^^^^^^^^ - -Performance ------------ - - Build performance under Cygwin is really not so bad, certainly not as good - as a Linux build. However, often you will find that the performance is - not just bad but terrible. If you are seeing awful performance.. like two - or three compilations per second.. the culprit is usually your Windows - Anti-Virus protection interfering with the build tool program execution. - - I use Cygwin quite often and I use Windows Defender. In order to get good - build performance, I routinely keep the Windows Defender "Virus & Threat - Protections Settings" screen up: I disable "Real-Time Protection" just - before entering 'make' then turn "Real-Time Protection" back on when the - build completes. With this additional nuisance step, I find that build - performance under Cygwin is completely acceptable. - -Strange Path Problems ---------------------- - - If you see strange behavior when building under Cygwin then you may have - a problem with your PATH variable. For example, if you see failures to - locate files that are clearly present, that may mean that you are using - the wrong version of a tool. For example, you may not be using Cygwin's - 'make' program at /usr/bin/make. Try: - - which make - /usr/bin/make - - When you install some toolchains (such as Yargarto or CodeSourcery tools), - they may modify your PATH variable to include a path to their binaries. - At that location, they may have GNUWin32 versions of the tools. So you - might actually be using a version of make that does not understand Cygwin - paths. - - The solution is either: - - 1. Edit your PATH to remove the path to the GNUWin32 tools, or - 2. Put /usr/local/bin, /usr/bin, and /bin at the front of your path: - - export PATH=/usr/local/bin:/usr/bin:/bin:$PATH - -Window Native Toolchain Issues ------------------------------- - - There are many popular Windows native toolchains that may be used with NuttX. - Examples include CodeSourcery (for Windows), devkitARM, and several vendor- - provided toolchains. There are several limitations with using a and Windows - based toolchain in a Cygwin environment. The three biggest are: - - 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are - performed automatically in the Cygwin makefiles using the 'cygpath' utility - but you might easily find some new path problems. If so, check out 'cygpath -w' - - 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links - are used in Nuttx (e.g., include/arch). The make system works around these - problems for the Windows tools by copying directories instead of linking them. - But this can also cause some confusion for you: For example, you may edit - a file in a "linked" directory and find that your changes had no effect. - That is because you are building the copy of the file in the "fake" symbolic - directory. If you use a Windows toolchain, you should get in the habit of - making like this: - - make clean_context all - - An alias in your .bashrc file might make that less painful. The rebuild - is not a long as you might think because there is no dependency checking - if you are using a native Windows toolchain. That bring us to #3: - -General Pre-built Toolchain Issues ----------------------------------- - - To continue with the list of "Window Native Toolchain Issues" we can add - the following. These, however, are really just issues that you will have - if you use any pre-built toolchain (vs. building the NuttX toolchain from - the NuttX buildroot package): - - There may be incompatibilities with header files, libraries, and compiler - built-in functions detailed below. For the most part, these issues - are handled in the existing make logic. But if you are breaking new ground, - then you may encounter these: - - 4. Header Files. Most pre-built toolchains will build with a foreign C - library (usually newlib, but maybe uClibc or glibc if you are using a - Linux toolchain). This means that the header files from the foreign - C library will be built into the toolchain. So if you "include ", - you will get the stdio.h from the incompatible, foreign C library and - not the nuttx stdio.h (at nuttx/include/stdio.h) that you wanted. - - This can cause confusion in the builds and you must always be - sure the -nostdinc is included in the CFLAGS. That will assure that - you take the include files only from - - 5. Libraries. What was said above header files applies to libraries. - You do not want to include code from the libraries of any foreign - C libraries built into your toolchain. If this happens you will get - perplexing errors about undefined symbols. To avoid these errors, - you will need to add -nostdlib to your CFLAGS flags to assure that - you only take code from the NuttX libraries. - - This, however, may causes other issues for libraries in the toolchain - that you do want (like libgcc.a or libm.a). These are special-cased - in most Makefiles, but you could still run into issues of missing - libraries. - - 6. Built-Ins. Some compilers target a particular operating system. - Many people would, for example, like to use the same toolchain to - develop Linux and NuttX software. Compilers built for other - operating systems may generate incompatible built-in logic and, - for this reason, -fno-builtin should also be included in your - C flags - - And finally you may not be able to use NXFLAT. - - 7. NXFLAT. If you use a pre-built toolchain, you will lose all support - for NXFLAT. NXFLAT is a binary format described in - Documentation/NuttXNxFlat.html. It may be possible to build - standalone versions of the NXFLAT tools; there are a few examples - of this in the buildroot repository at https://bitbucket.org/nuttx/buildroot - However, it is possible that there could be interoperability issues - with your toolchain since they will be using different versions of - binutils and possibly different ABIs. - -Building Original Linux Boards in Cygwin ----------------------------------------- - - Some default board configurations are set to build under Linux and others - to build under Windows with Cygwin. Various default toolchains may also - be used in each configuration. It is possible to change the default - setup. Here, for example, is what you must do in order to compile a - default Linux configuration in the Cygwin environment using the - CodeSourcery for Windows toolchain. After instantiating a "canned" - NuttX configuration, run the target 'menuconfig' and set the following - items: - - Build Setup->Build Host Platform->Windows - Build Setup->Windows Build Environment->Cygwin - System Type->Toolchain Selection->CodeSourcery GNU Toolchain under Windows - - In Windows 7 it may be required to open the Cygwin shell as Administrator - ("Run As" option, right button) you find errors like "Permission denied". - -Recovering from Bad Configurations ----------------------------------- - - Many people make the mistake of configuring NuttX with the "canned" - configuration and then just typing 'make' with disastrous consequences; - the build may fail with mysterious, uninterpretable, and irrecoverable - build errors. If, for example, you do this with an unmodified Linux - configuration in a Windows/Cgwin environment, you will corrupt the - build environment. The environment will be corrupted because of POSIX vs - Windows path issues and with issues related to symbolic links. If you - make the mistake of doing this, the easiest way to recover is to just - start over: Do 'make distclean' to remove every trace of the corrupted - configuration, reconfigure from scratch, and make certain that the set - the configuration correctly for your platform before attempting to make - again. - - Just fixing the configuration file after you have instantiated the bad - configuration with 'make' is not enough. - -DOCUMENTATION -^^^^^^^^^^^^^ - -Additional information can be found in the Documentation/ directory and -also in README files that are scattered throughout the source tree. The -documentation is in HTML and can be access by loading the following file -into your Web browser: - - Documentation/index.html - -NuttX documentation is also available online at http://www.nuttx.org. -

The change includes: + + * The wdog timer call backs used to support a variable number of arguments. +Now they support only a single argument ([PR +#1565](https://github.com/apache/incubator-nuttx/pull/1565)). This eliminates +(1) the configuration option `CONFIG_MAX_WDOGPARMS` and the OS interfaces +`wd_create()` and `wd_delete()` *   wdog timer data structures are no longer +pre-allocated. Now they are allocated by the caller of `wd_start()`. This (1) +eliminates the configuration options `CONFIG_PREALLOC_WDOGS` and +`CONFIG_WDOG_INTRESERVE`, (2) eliminates the type `WDOG_ID` which was a pointer +type to `struct wdog_s`, and (3) change the type of the first argument of all +remaining wdog interfaces functions from `WDOG_ID` to `FAR struct wdog_s *`. + +Because of these changes, all proprietary drivers maintained by all NuttX users +will require modification. The following summaries the required modifications: + + * Most drivers have a field in structure like `WDOG_ID wdog`; That must be +changed to `struct wdog_s wdog`; That changes the field from a pointer to a +`struct wdog_s` to the `struct wdog_s` storage itself. *   Eliminate all calls +to `wd_create()`. The `WDOG_ID` is not longer managed by the timing subsystem +and the `wd_create()` interface has been removed. *   The `wd_delete()` +interface has also been removed, but more care will need to be exercised: +`wd_delete()` also cancels any running timer so, in many case, calls to +`wd_delete()` should be replaced with calls to `wd_cancel()`. If you are certain +that the timer has never been started, then you must remove the call to +`wd_delete()` altogether. Calling `wd_cancel()` with an un-initialized s`truct +wdog_s` instance may well cause a fatal crash. *   Replace the first parameter +of all remaining wdog function calls from. For example, replace a call like `ret += wd_cancel(priv->wdog)` where `priv->wdog` was type `WDOG_ID` with the call +`ret = wd_cancel(&priv->wdog)`where `priv->wdog` is now type `struct wdog_s`. + + * [PR-1877](https://github.com/apache/incubator-nuttx/pull/1877) libc: + Implement "j" modifier for scanf + + * [PR-1864](https://github.com/apache/incubator-nuttx/pull/1864) libc: fs: Add + relative path support + + * [PR-1863](https://github.com/apache/incubator-nuttx/pull/1863) libc: + Implement `access()` + + * [PR-1866](https://github.com/apache/incubator-nuttx/pull/1866) libc: uio: + enable `writev()` for sockets + + * [PR-1853](https://github.com/apache/incubator-nuttx/pull/1853) libc: + Implement `popcount/popcountl/popcountll` + + * [PR-1850](https://github.com/apache/incubator-nuttx/pull/1850) Add tool for + parsing the callstack for Trace32 + + * [PR-1840](https://github.com/apache/incubator-nuttx/pull/1840) Add POLLPRI + for exception condition on the file descriptor + + * [PR-1828](https://github.com/apache/incubator-nuttx/pull/1828) Implement + mkdtemp syscall + + * [PR-1826](https://github.com/apache/incubator-nuttx/pull/1826) libc: Add + "tm\_zone" member to tm + + * [PR-1824](https://github.com/apache/incubator-nuttx/pull/1824) Implement + etpriority syscall + + * [PR-1821](https://github.com/apache/incubator-nuttx/pull/1821) Implement + gettid syscall + + * [PR-1818](https://github.com/apache/incubator-nuttx/pull/1818) Implement + pipe2 syscall + + * [PR-1779](https://github.com/apache/incubator-nuttx/pull/1779) libc: Minimal + umask implementation + + * [PR-1758](https://github.com/apache/incubator-nuttx/pull/1758) mm: Add lock + to protect call to mm\_addregion + + * [PR-1756](https://github.com/apache/incubator-nuttx/pull/1756) libc: + Implement gethrtime, getrlimit, setrlimit + + * [PR-1658](https://github.com/apache/incubator-nuttx/pull/1658) libc: Add + stubs for utimes + + * [PR-1615](https://github.com/apache/incubator-nuttx/pull/1615) libc: + Implement tm::tm\_gmtoff field + + * [PR-1611](https://github.com/apache/incubator-nuttx/pull/1611) libc: Allocate + file\_struct dynamically + + * [PR-1684](https://github.com/apache/incubator-nuttx/pull/1684) Add gdb script + for NuttX thread debugging + + * [PR-1607](https://github.com/apache/incubator-nuttx/pull/1607) mm: Implement + malloc\_usable\_size + + * [PR-1606](https://github.com/apache/incubator-nuttx/pull/1606) sched/pthread: + Implement pthread\_attr\_detachstate + + * [PR-1600](https://github.com/apache/incubator-nuttx/pull/1600) Implement + epol\_pwait and EPOLLONESHOT flag + + * [PR-1597](https://github.com/apache/incubator-nuttx/pull/1597) sched: Support + passing non empty argument to init task + + * [PR-1596](https://github.com/apache/incubator-nuttx/pull/1596) libc: Replace + all sem\_xxx with \_SEM\_XXX.

To build these binaries, it needs to know the host C +compiler and C flags. Previously, every board's `scripts/Make.defs` file had to +provide this information via `HOSTCC` and `HOSTCFLAGS` Definitions. As part of +an effort to simplify the build system, these definitions are now automatically +provided by logic in `tools/Config.mk`. Boards included in the NuttX repository +have been updated, but if you are building NuttX for a custom board, you may +want to make the following changes: + +In your custom board's `scripts/Make.defs` file, remove lines like these: + +HOSTCC = gcc HOSTCFLAGS = -Wall -Wstrict-prototypes -Wshadow -Wundef -g -pipe + +Sometimes they may look like this: + +ifeq ($(CONFIG\_WINDOWS\_NATIVE),y) +  HOSTCC = mingw32-gcc.exe +else +  HOSTCC = gcc +endif + +Note: These changes are OPTIONAL. + +You may still set these definitions in your board's scripts/Make.defs, and your +definitions will override the ones in tools/Config.mk. + +Also, you may override these definitions for a single run by providing them on +the make command line. This is useful if, for example, you wish to build debug +versions of these host binaries: define HOSTCFLAGS with -g on the command line. + +See * [PR-1398](https://github.com/apache/incubator-nuttx/pull/1398), git +commit +#[ee875b2a260cb4cc532b8ca303c2515e24c39b4e](https://github.com/apache/incubator-nuttx/commit/ee875b2a260cb4cc532b8ca303c2515e24c39b4e) +in the main NuttX repository. + +### Removal of Unused `ARCHCCVERSION` and `ARCHCCMAJOR` + +The ARCHCCVERSION and ARCHCCMAJOR variables are unused.

[2caf3a69e3d60ec550980f7ba897c732e7a39df7](https://github.com/apache/incubator-nuttx/pull/1890/commits/2caf3a69e3d60ec550980f7ba897c732e7a39df7)) +attempts to speed up compilation time for concurrent builds by changing +assignment to makefile variables `*CFLAGS*`, `*CPPFLAGS*`, `*CXXFLAGS*`, and +`*AFLAGS*` from recursive `=` to simple `:=`. This causes these compile +options to be expanded only once during the build. + +If you are using NuttX on a custom board not in the NuttX repository, you may +want to make a similar change to your `Make.defs` files. Change these +recursive assignments: + +``` +CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe +CXXFLAGS = $(ARCHCXXFLAGS)

This requires all linker options to be prefixed with `-Wl,` (dash, capital W, lower-case L, comma). All boards in the NuttX tree have been updated, but any custom out-of-tree boards will need to apply this change in the relevant parts of their build scripts. + +The reason for this change is that GNU Binutils 2.36.x has added new error checking on command line arguments. This has had the effect that the NuttX build suddenly broke on host OS distributions that updated to the 2.36.x release line. Reports included Arch, Manjaro, and Ubuntu. Other host OSes are likely to be affected as well. + +#### Symptoms + +Your toolchain and board are affected if you see errors from LD like: + +``` +arm-none-eabi-ld: Error: unable to disambiguate: -nostartfiles (did you mean --nostartfiles ?) +``` + +or (following this change in NuttX) errors from GCC like: + +``` +arm-none-eabi-gcc: error: unrecognized command line option '--gc-sections'; did you mean '--data-sections'? +``` + +#### What to change + +The most common change expected to affect most boards: + +Change: + +``` +NXFLATLDFLAGS1 = -r -d -warn-common +NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections +``` + +to: + +``` +NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common +NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -Wl,-no-check-sections +``` + +If doing a kernel build, you may need changes in your board's `kernel/Makefile` like: + +Change: + +``` +USER_LDFLAGS = --undefined=$(ENTRYPT) --entry=$(ENTRYPT) $(USER_LDSCRIPT) +``` + +to: + +``` +USER_LDFLAGS = -Wl,--undefined=$(ENTRYPT) -Wl,--entry=$(ENTRYPT) $(USER_LDSCRIPT) -nostartfiles -nodefaultlibs +``` + +Change: + +``` +$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) --start-group $(USER_LDLIBS) --end-group $(USER_LIBGCC) +``` + +to: + +``` +$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) -Wl,--start-group $(USER_LDLIBS) -Wl,--end-group $(USER_LIBGCC) +``` + +Depending on your board's customized build scripts, you may need to look out for other `make` variables in your board's `Makefile` or `Make.defs`. + +Some variables to look for: + +- `ARCHSCRIPT` +- `ARCH_LIBS` +- `CCLINKFLAGS` +- `EXTRALINKCMDS` +- `LDELFFLAGS` +- `LDENDGROUP` +- `LDFLAGS` +- `LDLINKFLAGS` +- `LDMODULEFLAGS` +- `LDSTARTGROUP` +- `NXFLATLDFLAGS1` +- `NXFLATLDFLAGS2` +- `USER_LDFLAGS` + +Anything that executes LD, such as: + +``` +$(Q) $(LD) --entry=__start $(LDFLAGS) $(LIBPATHS) $(EXTRA_LIBPATHS) \ +``` + +Anything that processes LD flags, such as: + +``` +$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map" +``` + +In general, any command line options destined for LD must be prefixed with `-Wl,` (dash, capital W, lower-case L, comma) since they are now being passed through GCC. + +#### Examples + +Change: + +``` +EXTRALINKCMDS += @$(TOPDIR)/syscall/syscall_wraps.ldcmd +``` + +to: + +``` +EXTRALINKCMDS += -Wl,@$(TOPDIR)/syscall/syscall_wraps.ldcmd +``` + +Change: + +``` +LDFLAGS += -gc-sections +``` + +to: + +``` +LDFLAGS += -Wl,-gc-sections +``` + +Change: + +``` +$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map" +``` + +to: + +``` +$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Wl,-Map="$(TOPDIR)$(DELIM)nuttx.map" +``` + +Change: + +``` +NXFLATLDFLAGS1 = -r -d -warn-common +``` + +to: + +``` +NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common +``` + +Change: + +``` +ifeq ($(CONFIG_CYGWIN_WINTOOL),y) +LDFLAGS += -Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" --cref +else +LDFLAGS += -Map=$(TOPDIR)/nuttx.map --cref +endif +``` + +to: + +``` +ifeq ($(CONFIG_CYGWIN_WINTOOL),y) +LDFLAGS += -Wl,-Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" -Wl,--cref +else +LDFLAGS += -Wl,-Map=$(TOPDIR)/nuttx.map -Wl,--cref +endif +``` + +Also, if you have assigned the LD variable, it would need to change as well: + +Change: + +``` +LD = $(CROSSDEV)ld +``` + +to: + +``` +LD = $(CROSSDEV)gcc +``` + +#### References + +* Git commit # 45672c269db13f59bdaa417e564837e8bbb6c8c1 in the NuttX main repository: +- https://github.com/apache/incubator-nuttx/commit/45672c269db13f59bdaa417e564837e8bbb6c8c1 +* PR-3836 in the NuttX main repository: +- https://github.com/apache/incubator-nuttx/pull/3836 +* Issues 3209 and 3826 in the NuttX issue tracker: +- https://github.com/apache/incubator-nuttx/issues/3209 +- https://github.com/apache/incubator-nuttx/issues/3826 +* Description of the change on Binutils mailing list: +- https://sourceware.org/pipermail/binutils/2021-June/116826.html +* Description of -Wl,option in the GCC manual: +- https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html diff --git a/drivers/bch/bch.h b/drivers/bch/bch.h index eeaad6dc98c0b878aa086ccbe07531166c72fcf8..fcab9a18efff79a55441bcf475468c67acef907b 100644 --- a/drivers/bch/bch.h +++ b/drivers/bch/bch.h @@ -1,35 +1,20 @@ /**************************************************************************** * drivers/bch/bch.h * - * Copyright (C) 2008-2009, 2014-2015 Gregory Nutt.
