This was necessary to keep - the stack usage down for the 8051/2 (which has only - 256 bytes of stack). - * Attempts to use C5471 console from interrupt handlers - can cause errors. Added a special path for this case. - * Refuse calls to sem_wait and sem_trywait from interrupt - handlers. This was happening because interrupt handlers - were calling printf-like functions. - * Added strtok() and strtok_r() - * Added a simple shell called nsh (see examples/nsh). - * Platform support for 8052 is complete but not stable - when the timer interrupt is enabled. Seems to be an - issue when SP enters indirect address space. - * Documentation updates - -0.1.2 2007-03-19 Gregory Nutt <gnutt@nuttx.org> - - * Add dirent.h, opendir(), readdir(), closedir(), etc. - * Add strerror() - * Added 'ls' command to nsh - * Added C5471 watchdog driver - * Fixed another bug where free() is called from IDLE task. - Can't do this; the caller must be able to wait for access - to memory. - * Fixed bugs associated with debug output: - Cannot do dbg() in middle of context switch logic. - because it may require use of semaphores and cause - additional context switches. lldbg() is safe. - * Interrupt must be disabled throughout all context switches. - * Separated C5471 serial driver; a shareable part is - in drivers/. ; the C5471 specific part is in arch/C5471. - serial.h defines the interface. - * Fixed mq_receive() and mq_send(): bad memcpy() - * Fixed C5471 signal deliver logic: use of dbg() and - other actions by use signal handler can alter errno. - need to protect errno during signal handling. - * Fixed uninitialized variable in filesystem that could - cause various problems - * Added a test for roundrobin scheduler. - -0.2.1 2007-03-22 Gregory Nutt <gnutt@nuttx.org> - - * Fix error in handing signed decimal in vsprintf(). - * Major restructuring of header files to get closer to - POSIX compliance. - * Eliminate compilation warnings that crept into recent check-ins - * Add kill() - * Added support for POSIX timers - * Some Documentation updates - * Added support for the Neuros OSD / DM320 - -0.2.2 2007-03-26 Gregory Nutt <gnutt@nuttx.org> - * Created the configs/ directory; separated board configuration - from processor architecture logic - * Add memory leak detection test to examples/ostest - * Corrected memory leak in OS pthread join logic - * Corrected memory leaks in examples/ostest due to failures - to join or detach from pthreads. - * Added pthread_once(), pthread_kill(), pthread_sigmask() - * Added pthread_barrierattr_*() APIs - * Added pthread_barrier_init(), pthread_barrier_destroy(), and - pthread_barrier_wait(); - * Added pthread barrier test - * Added protection so that errno cannot be modified from - interrupt handling. - * sched_setparam(), sched_setscheduler() now correctly set - errno; pthread_setscheduler() now returns the correct errno. - * Added pthread_setschedprio(). - * Added directories to hold board-specific header files - * Added directories to hold board-specific drivers - -0.2.3 2007-03-29 Gregory Nutt <gnutt@nuttx.org> - - * mq_receive and mq_send now return errno's appropriately - * mq_receive and mq_send are now correctly awakened by signals. - * Fixed an unmatched sched_lock/unlock pair in task_delete(). - * sched_lock must be called in _exit() because operation of - task_delete() can cause pending tasks to be merged and a - context switch to occur. - * Added mq_timedreceive() and mq_timedsend() - * signal mask is now inherited by both child tasks and threads. - * Improved sharebility of stdout among pthreads (only). Nothing - was broken, but by moving the mutual exclusion logic to a - higher level, the printf output is more readable. - * Fixed a bug in file system cleanup: A list was being deleted - before the buffers contained in the list. - * Fixed a bug in the wait-for-message-queue-not-empty logic. - * Added a test of timed mqueue operations; detected and corrected - some mqueue errors. - * Identified and corrected a race condition associated with - pthread_join. In the failure condition, memory was being - deallocated while still in use. - -0.2.4 2007-04-28 Gregory Nutt <gnutt@nuttx.org> - - * Verified c5471 build under Cygwin on WinXP - * Makesystem changes to better support different SoCs. - * Made arch/c5471/include and arch/dm320/include identical in - preparation for merging into arch/arm - * Logic from arch/c5471 and arch/dm320 combined into arch/arm. - arch/c5471 and arch/dm320 are deprecated and will be removed - when the new c5471 and dm320 logic is verified. - -0.2.5 2007-05-19 Gregory Nutt <gnutt@nuttx.org> - - * Corrected some build/configuration issues introduced with the - last release. - * Added support for the NXP 214x processor on the mcu123.com lpc214x - development board (untested) - * Added support for block devices. - * Simulated target now exports a VFAT filesystem - * Begin support for VFAT filesystem (missing functionality) - * Added mount() and umount() - * Fix bug in memcmp return value - * Fix errors in timeslice calculation (several places) - * Added missing irqrestore() in timer_deleteall(). - * close() was not closing the underlying device. - * Added fsync() - * Added strspn() and strcspn() - -0.2.6 2007-05-26 Gregory Nutt <gnutt@nuttx.org> - - * Added unlink(), mkdir(), rmdir(), and rename() - * Fixed several serious FAT errors with oflags handling (&& instead of &) - * Added FAT support for unlink(), mkdir(), rmdir(), and rename - * Added FAT support for opendir(), closedir(), readdir(), seekdir(), - telldir(), rewindir(). - * Fixed ARM compilation errors introduced in 0.2.5 (that is what I get - for only testing on the simulation). - -0.2.7 2007-06-09 Gregory Nutt <gnutt@nuttx.org> - - * Added stat() to fs layer and to FAT - * Fixed reference counting errors associated with mounted filesystems - * Added fat_getattrib() and fat_setattrib() - * Added statfs() to fs layer and to FAT - * Correct file name extension in tools/zipme.sh - * Fix error in dependencies in 8051/2 Makefile - * sched/Makefile: Don't build sleep() or usleep() if signals are disabled - * sched/sched_setparam.c: Remove redundant disabling of interrupts - * sched/usleep.c: Fixed nsec calculation - * lib/lib_strcspn.c: Function incorrectly named strspn(). - * examples/ostest/main.c: Errors in SDCC version of a memcpy() call - * examples/ostest/sighand.c: Don't call fflush() if streams are disabled - * include/limits.h, include/time.h, sched/clock_internal.h: A support for - using selectable system timer frequency. - * Fixed error in mountpoint related conditional compilation introduced - in 0.2.5 - * Restructured some Makefiles to better handle enabling and disabling - NuttX features without having so much conditional compilation in the - source files. - * tools/mkconfig.c: No longer depends on asprintf() and _GNU_SOURCE and - so should now build in non-GNU, non-GLIBC environments. - * include/nuttx/compiler.h: Fix for using SDCC with the Z80. - * include/assert.h & arch/pjrc-8051/src/up_assert.c: SDCC does support - __FILE__and __LINE__ (not tested) - * examples/ostest/barrier.c: Don't call usleep() when signals are - disabled. - -0.2.8 2007-07-02 Gregory Nutt <gnutt@nuttx.org> - * tools/Makefile.mkconfig: Under Cygwin, executable has a different name - * tools/mkdeps.sh & arch/arm/src/Makefile: Corrected a problem makeing dependencies - * tools/zipme.sh: Force directory name to be nuttx-xx.yy.zz - * fs/fs_opendir.c: Correct errors in semaphore usage that can cause deadlock. - * lib/lib_getopt.c: Added getopt() support - * examples/nsh/: NSH now supports cat, mount, umount, and mkdir. ls supports - -l -s, and -R - * Added basic OS support to manage environment variables: environment - storage, cloning on task creation, sharing on pthread creation, destruction - on thread/task exit. - * Add environment variables APIs: environ, getenv, putenv, clearenv, setenv, - unsetenv - * Correct an error in realloc() when the block is extended "down" in memory. - In this case, the old memory contents need to be copied to the new location - and an allocated bit was not being set. - * examples/ostest/: Added an environment variable test. - * examples/nsh/: Break into several files. - * lib/: Added strrchr, basename, dirname - * examples/nsh/: Add cp, rm, rmdir, set, unset commands. echo will now print - environment variables. - -0.3.0 2007-11-06 Gregory Nutt <gnutt@nuttx.org> - - * Imported uIP into the tree (see - http://www.sics.se/~adam/uip/index.php/Main_Page) - * Adding socket(), bind(), connect() - * Added snprintf() - * Added send() and sendto();

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 <gnutt@nuttx.org> - * 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 not 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 <gnutt@nuttx.org> - * 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 <gnutt@nuttx.org> - * 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 <gnutt@nuttx.org> - * 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 <gnutt@nuttx.org> - - * 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 intialization 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 <gnutt@nuttx.org> - - * z8Encore! and eZ80Acclaim!: Fixed the serial driver initialization sequence - * eZ80Acclaim!: Fixed error in vector table: Missing space set aside for the - "unused" vectors. As a result, all vectors above timer4 were skewed. - * eZ80Acclaim!: Fixed logic error in UART interrupt handler. - * Many fixes in FAT file system and in NSH for correct compilation with ZDS-II - * eZ80Acclaim!: Added and verified a NuttShell (NSH) configuration. - * eZ80Acclaim!: Correct endian-ness; defconfig files said BIG endian. - * Restructured parts of the uIP port for correct compilation with ZDS-II - * eZ80Acclaim!: Complete basic integration of the eZ80F91 EMAC driver. 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 <gnutt@nuttx.org> - - * 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: Corrrect 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * Change SPI interface so that is can accomodate 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. Added a configuration to build - examples/ostest. - * arch/arm/src/lpc214x: Add configuration option to enable fast GPIO (vs. - legacy, "slow" GPIO) for LPC214x. - * arch/arm: Restructured the arch/arm directory structure to better support ARM - and Cortex-M3. - * sched/: pthread_create() must return a (non-negated) errno value on failure. - * configs/eagle100/nsh: Add a NuttShell (NSH) configuration for the Eagle-100 - -0.4.7 2009-05-29 Gregory Nutt <gnutt@nuttx.org> - - * arch/arm/src/lm3s: Added an Ethernet driver for the LM3S6918 - * configs/eagle100/nettest: Added an examples/nettest configuration for the - Micromint Eagle100 board. - * Documentation/NuttxPortingGuide.html: Added a section on NuttX device drivers. - * configs/eagle100/httpd: Added an examples/uip configuration for the - Micromint Eagle100 board. - * arch/arm/src/lm3s: Added an SSI driver for the LM3S6918 - * examples/nsh: Added MMC/SD support for the LM3S6918 - * arch/arm/src/lm3s: Fix logic for setting and clearing output GPIOs (critical - fix!). - * drivers/mmcsd: Found numerous errors in current MMC/SD SPI driver. 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. Re-verified SDC ver1.x support with 1Gb Toshiba SDC, 1Gb PNY SDC, and - 4Gb Kingston SDHC. 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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. - * confgs/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 <gnutt@nuttx.org> - - * 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!

I still don't - have a test to prove that the changes are correct. - * configs/olimex-lpc2378: Add support for the CodeSourcery toolchain - under Linux (contributed by Alan Carvalho de Assis). - * arch/arm/src/lpc17xx/lpc17_gpio.c: Fix an important GPIO configuration - bug: When attempting to set no pull-up or pull-down (floating), - it would, instead, select pull-down. - * arch/arm/src/lm3s/lm3s_gpioirq.c: Fix warning for returning a value - from functions returning void (contributed by Tiago Maluta). - * netutils/dhcpc/dhcpc.c: lease_time was not in host order - * examples/uip/main.c: if DHCPC is selected, this example now shows - the assigned IP address. - * arch/arm/src/lm3s and arch/arm/include/lm3s: Definitions for the - TI LM3S9B96 contributed by Tiago Maluta. - * arch/arm/src/lm3s/lm3s_gioirq.c: Fix a logic error in the address - table lookup. - * arch/arm/src/lm3s/lm3s_gioirq.c: Also needs to enable the global - GPIO interrupts. - * arch/arm/src/lm3s/lm3s_internal.h and lm3s_gpio.c: Fixed the encoding - of GPIO port number that limited support for GPIO ports to 8 - * sched/pg_*.c and *.c and include/nuttx/page.h: Implemented the - common, core logic for on-demand paging. See - http://www.nuttx.org/NuttXDemandPaging.html for details. - * drivers/usbdev/usbdev_serial.c: Correct compilation errors that - occur if CONFIG_USBDEV_DUALSPEED is selected. - * configs/ea3131/pgnsh: Add an NSH configuration with on-demand paging - enabled. 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 <gnutt@nuttx.org> - - * 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 - desciption). 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 <gnutt@nuttx.org> - - * 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: http://tech.groups.yahoo.com/group/nuttx/message/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 <gnutt@nuttx.org> - - * 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. - * confgs/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 <gnutt@nuttx.org> - - * 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 desciptor 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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/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 <gnutt@nuttx.org> - - * 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/lp17_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 <gnutt@nuttx.org> - - * 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/<board>/<config>/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 <gnutt@nuttx.org> - - * 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 kernal 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 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 seversl 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 Kinetics TWR-K60N512 board is - now functional. - * confgs/twr-k60n512: Add Kinetics 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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.

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/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. It was - not being recognized and handled properly. - * graphics/nxsu/nx_releasebkgd.c: Fix a bad cast that was causing - problems with the background window was released. - * fs/nxffs/nxffs_pack.c: Correct a critical bug in the NXFFS file system: - When repacking the filesystem, there was a missing check to see if an - inode structure would fit at the end of a block. 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/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 <gnutt@nuttx.org> - - * 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. (Thanks to David Sidrane). - * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the - STM32F40xxx family of MCUs. - * configs/stm3240g-eval: Add framework for the STMicro STM3240G-EVAL - board. - * include/sys/types.h: wchar_t is a builtin type in C++ and its - declaration can cause errors with certain C++ compilers. - * sched/sig_timedwait.c: Fix signal handling when the returned info - is NULL.

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.

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 <gnutt@nuttx.org> - - * 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. Contributed by Gary Teravskis, - * configs/stm3220g-eval: Add support for the STMicro STM3220G-EVAL board. - Contributed by Gary Teravskis, - -6.17 2012-04-14 Gregory Nutt <gnutt@nuttx.org> - - * configs/sure-pic32mx: Add support for the Sure DB-DP11212 PIC32 General - Purpose Demo Board - * arch/arm/src/stm32/stm32_usbhost.c/.h: Add files that will (eventually) - hold an STM32 USB host driver (the initial check-in is the NuttX LPC17 - USB host driver with name changes only). - * arch/arm/src/stm32/chip/stm32_otgfs.h: STM32 USB OTG FS register - definitions (not complete on initial check-in). - * net/connect.c: Add another low level, thread-independent socket interface - for use within the OS. - * arch/mips/src/pic32mx/pic32mx_ethernet.c: The PIC32 Ethernet driver - is now stable on the PIC32 Starter Kit. - * configs/pic32-starterkit/nsh2: Add a PIC32 Ethernet Starter Kit NSH - configuration that has no serial console; all interaction is done via - Telnet. - * net/netdev_sem.c: Correct a deadlock condition by making a seamphore - recursive. 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 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 <gnutt@nuttx.org> - - * 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_internal.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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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 <gnutt@nuttx.org> - - * 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/lpc32_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 necesary). - -6.22 2012-09-29 Gregory Nutt <gnutt@nuttx.org> - - * 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 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. - * confgs/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 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 psuedo-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 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 <gnutt@nuttx.org> - - * 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 the the uClibc++ is - complete and verified for the STM32 platform. - -6.24 2012-12-20 Gregory Nutt <gnutt@nuttx.org> - - * 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 the 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 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. - * confgs/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/<many>/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 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 <gnutt@nuttx.org> - - * 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 serialized "out-of-band" 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).

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 overruning 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.

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.

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).
