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.

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.

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.

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.

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).

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.

Contributed by - Kate. - * apps/netutils/webserver/httpd/c: Fix a typo that as introduced in - version r4402: 'lese' instead of 'else' (Noted by Max Holtzberg). - * 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). - * apps/netutils/webserver, apps/examples/uip, and apps/include/netutils/httpd.h: - The "canned" version of the uIP web servers content that was at - netutils/webserver/httpd_fsdata.c has been replaced with a dynamically - built configuration located at apps/examples/uip (Contributed by - Max Holtzberg). - * apps/netutils/webserver: Several inenhancements from Kate including the - ability to elide scripting and SERVER headers and the ability to map - files into memory before transferring them. - * apps/netutils/webserver: Add ability to map a URL to CGI function. - Contributed by Kate. - * apps/nshlib/nsh_mntcmds.c: The changes of 6.21 introduced holes in the - error handling: Now the number of arguments to mount can be 0 or 4. - Additional parameter checking is required to prevent mysterious errors - (submiteed by Kate). - * apps/netutils/webserver/httpd_mmap.c: Fix errors when the mmap() - length is zero (submitted by Kate). - * apps/netutils/webserver/httpd_sendfile.c: Add and option, - CONFIG_NETUTILS_HTTPD_SENDFILE to transfer files using the NuttX - sendfile() interface. - * apps/netutils/discover: A UDP network discovery utility contributed - by Max Holtzberg. - * apps/examples/discover: A test example for the UDP network discovery - utility (also contribed by Max Holtzberg). - * apps/examples/*/main.c: Too many files called main.c. Each renamed - to something unique so that they will not collide in the archive. - * apps/netutils/xmlrpc: The Embeddable Lightweight XML-RPC Server - discussed at http://www.drdobbs.com/web-development/\ - an-embeddable-lightweight-xml-rpc-server/184405364. Contributed by - Max Holtzberg. - * apps/netutils/uip_listenon.c: Logic in uip_server.c that creates - the listening socket was moved to this new file to support re-use. - Contributed by Kate. - * apps/netutils/webserver/httpd.c: The option CONFIG_NETUTILS_HTTPD_SINGLECONNECT - can now be used to limit the server to a single thread. Option - CONFIG_NETUTILS_HTTPD_TIMEOUT can be used to generate HTTP 408 errors. - Both from Kate. - * apps/netutils/webserver/httpd.c: Improvements to HTTP parser from - Kate. - * apps/netutils/webserver/httpd.c: Add support for Keep-alive connections - (from Kate). - * apps/NxWidget/Kconfig: This is a kludge. I created this NxWidgets - directory that ONLY contains Kconfig. NxWidgets does not live in - either the nuttx/ or the apps/ source trees. This kludge makes it - possible to configure NxWidgets/NxWM without too much trouble (with - the tradeoff being a kind ugly structure and some maintenance issues). - * apps/examples/Make.defs: Missing support for apps/examples/watchdog. - * apps/NxWidgets/Kconfig: Add option to turn on the memory monitor - feature of the NxWidgets/NxWM unit tests. +nuttx-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.

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.

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 documentionof the binary loader. + * configs/sim/ostest: Converted to use the mconfig 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. + +apps-6.23 2012-11-05 Gregory Nutt <gnutt@nuttx.org> + + * vsn: Moved all NSH commands from vsn/ to system/. Deleted the vsn/ + directory. + * Makefile: Change order of includes when CONFIG_NEWCONFIG=y. In + that case, namedapp must be included first so that the namedapp + context is established first. If the namedapp context is established + later, it will overwrite any existing namedapp_list.h and nameapp_proto.h + files. + * CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences + of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*. + * Kconfig: Fleshed out apps/examples/adc/Kconfig and apps/examples/wget/Kconfig. + There are still a LOT of empty, stub Kconfig files. + * Kconfig: Fleshed out apps/examples/buttons/Kconfig. There are still a LOT + of empty, stub Kconfig files. + * apps/netutils/webserver/httpd.c: Fix a bug that I introduced in + recent check-ins (Darcy Gong). + * apps/netutils/webclient/webclient.c: Fix another but that I introduced + when I was trying to add correct handling for loss of connection (Darcy Gong) + * apps/nshlib/nsh_telnetd.c: Add support for login to Telnet session via + username and password (Darcy Gong). + * apps/netutils/resolv/resolv.c (and files using the DNS resolver): Various + DNS address resolution improvements from Darcy Gong. + * apps/nshlib/nsh_netcmds.c: The ping command now passes a maximum round + trip time to uip_icmpping(). This allows pinging of hosts on complex + networks where the ICMP ECHO round trip time may exceed the ping interval. + * apps/examples/nxtext/nxtext_main.c: Fix bad conditional compilation + when CONFIG_NX_KBD is not defined. Submitted by Petteri Aimonen. + * apps/examples/nximage/nximage_main.c: Add a 5 second delay after the + NX logo is presented so that there is time for the image to be verified. + Suggested by Petteri Aimonen. + * apps/Makefile: Small change that reduces the number of shell invocations + by one (Mike Smith). + * apps/examples/elf: Test example for the ELF loader. + * apps/examples/elf: The ELF module test example appears fully functional. + * apps/netutils/json: Add a snapshot of the cJSON project.
