This is a requirement for eXecute + In Place (XIP) support. + * Add mmap() API with restricted capability (only for XIP support) + * Extend ROMFS test at /examples/romfs to verify mmap() and XIP support. + * Add support for Intel Hex format output using objcopy + * Completed the basic port of the NXP LPC2148 on the mcu123.com board. + The basic port includes successful booting, timer interrupts, serial console, + succesfully passing the examples/ostest, and a NuttShell (NSH) configuration. + * ARM architectures now support drivers/lowconsole.c + +0.3.16 2008-10-10 Gregory Nutt <gnutt@nuttx.org> + * Added header files defining a common USB device controller architecture + * Added USB device side driver for the LPC214x + * Correct the frequency of system timer interrupts in the NXP LPC214x port + (off by 20x in nuttx-0.3.15) + * Add an option to set aside a separate stack for interrupt handling (ARM only). + This is useful when memory is constrained, there are multiple tasks, and + the interrupt stack requirement is high (as when USB is enabled). + * Added USB serial class device side driver (emulates Prolific PL2303 + serial-to-USB adaptor) + * Add LPC214x USB serial configuration; Add examples/usbserial test + * Added USB device side driver for the DM320 (untested at initial release) + * Fixed an error in a previous (post 0.3.15) check-in that broke the LPC214x + system timer. + * Fixed serial driver bugs related to (1) open counts and (2) recognizing + O_NONBLOCK on read. + * Fixed an error in read(); it was not setting the errno on errors returned + from the driver. + +0.3.17 2008-10-28 Gregory Nutt <gnutt@nuttx.org> + * Incorporate patch "[2164503] nuttx-0.3.16 does not build for ARM with USB disabled" + * Reduced the amount of memory reserved for USB serial control requests. 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 (16Kb 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!

As of the 5.6 release, there is a complete set of + LPC17xx header files defining all bits in all LPC17xx registers, + but little else (I still do not have hardware in hand). + * drivers/mtd/m25px.c: Add support for M25P1 flash part (See NOTE) + * include/nuttx/i2c.h: Extended I2C interface definition to handle + multiple transfers (See NOTE). + * include/nuttx/usbdev.h: Corrected an important macro definition + needed to correctly handle USB null packet transfers (See NOTE). + * arch/arm/src/lpc313x: New drivers: I2C and SPI.

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 (16Kb). 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 8Kb at the beginning of Bank0; the 8Kb 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.

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/uart_16550.c and include/nuttx/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 64Kb. 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 + 64Kb 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 + examplex/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 (Lzzy)) + * arch/arm/src/lpc17xx/lpc17_can.h: Revised CAN driver submitted by + Li Zhuoy (Lzzy). 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 (Lzzy)). + * 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 (Lzzy)). + * 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. This one + supports X11 graphics, C++, and exercises graphic functions as built-in + commands. + +6.11 2011-11-12 Gregory Nutt <gnutt@nuttx.org> + + * arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not + selected. Doing so will cause errors if other configuration dependencies + are not met. + * configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD + do not work with R61580 LCD. + * configs/pic32-starterkit: Beginning of a configuration for the Microchip + PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this + with no serial port?! + * lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it + closes a read-only file. This is because it calls flush() which will + fail on read-only files. No harm is done other that a bad value is + returned. + * arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old + libboard.a was not being cleaned. + * arch/mips/src/pic32mx/pic32mx-gpio*.c: Add GPIO support for the PIC32MX. + * configs/sure-pic32mx/src/up_leds.c and up_buttons.c: Add button and LED + support for the Sure Electronics PIC32MX board. + * configs/ea3152: Add a configuration for the Embedded Artists LPC3152 + daughter board (with the same base-board used with configs/ea3131) + * graphics/nxmu/nx_getrectangle.c, graphics/nxsu/nx_getrectangle.c, + graphics/mxtk/nx_getwindow.c, graphics/nxmu/nx_gettoobar.c: New + interfaces to read from graphics memory + * graphics/nxbe/nxbe_bitmap.c: Fix an error in the error handling that + can cause valid bitmaps to fail to render. + * include/nuttx/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. Before this change, it would derefence a NULL pointer + in this case. + * graphics/nxfonts/nxfonts_sans17x22.h and nxfonts_sans20x26.h: Add + some very small sans serif fonts. + * graphics/nxfonts/nxfonts_sans17x23b.h and nxfonts_sans20x27b.h: Add + corresponding sans serif bold fonts. + * drivers/input/ads7843e.c and tsc2007.c: Fix some errors in the poll + setup error checking that was cloned into both drivers. + * sched/mq_notify.c: Set errno appropriately on failures. There are + still several message queue functions that do not set errno! + * arch/arm/src/stm32: Fixes to several STM32F40xxx files (contributed by + Mikhail Bychek). + * configs/stm3210e-eval/src/up_lcd.c: Fix banding problem on the R61580 + LCD + * configs/stm3240g-eval/ostest: The basic STM32F40xx bringup is functional + (11/12/06) for the STM3240G-EVAL board and passes the OS test. + * configs/stm3240g-eval/nsh: Adds a NuttShell (NSH) configure for the + STM3240G-EVAL board. + +6.13 2012-xx-xx Gregory Nutt <gnutt@nuttx.org> + + * arch/arm/src/stm32/stm32f40xxx_dma.c: Add DMA support for the STM32 F4 + family (untested on initial check-in) + * arch/arm/src/armv7-m/up_fpu.c: Add logic for saving an restoring VFP + floating point registers on context switches (but also disable the FPU + because CodeSourcery doesn't support hard flowing point!) + * arch/arm/src/stm32/chip/stm32_eth.h: Add Ethernet register definitions + for the STM32 F4. + * arch/arm/srcm/stm32/stm32_eth.c: Adds an Ethernet driver for the STM32 F4. + * arch/arm/srcm/stm32/stm32_dac.c and stm32_adc.c: "Skeleton" files for STM32 + DAC and ADC drivers. The actual logic will come later. + * arch/arm/srcm/stm32/stm32_eth.c: There may be a few more lurking bugs, but + the STM32 Ethernet driver appears to be fully functional on the STM3240G-EVAL. + * arch/arm/srcm/stm32/stm32_eth.c: Fix an error in clearing abnormal interrupt + events. + * configs/stm3240g-eval/dhcpd: Add a DCHP daemon configuration for the + STM3240G-EVAL board. + * configs/stm3240g-eval/nettest: Add a network test configuration for the + STM3240G-EVAL board. + * arch/arm/srcm/stm32/stm32_rtc.c, stm32f10xxx_rtc.c, and stm32f40xxx_rtc: + Broke out separate drivers to handle the very different RTC implementations + in the STM32 F1 and F4 family. + * arch/arm/srcm/stm32/stm32f10xxx_rtc.c: STM32 F4 RTC is functional (12/14/2011) + * net/uip-arp.c: Fix compilation issue with CONFIG_NET_ARP_IPIN + * include/nuttx/pwm.h and drivers/pwm.c: Add an interface definition and a + "upper half" driver for PWM output. + * arch/arm/src/stm32/stm32_pwm.c: Added a PWM "lower half" driver for the + STM32. 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. Theses changes also include support for the STM32F103VCT6. + + |
