NuttX-6.22
|
|
----------
|
|
|
|
The 89th release of NuttX, Version 6.22, was made on September 29, 2012,
|
|
and is available for download from the SourceForge website. Note
|
|
that release consists of two tarballs: nuttx-6.22.tar.gz and
|
|
apps-6.22.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|
|
file for build information).
|
|
|
|
This release corresponds with SVN release number: r5206
|
|
|
|
Note that all SVN information has been stripped from the tarballs. If you
|
|
need the SVN configuration, you should check out directly from SVN. Revision
|
|
r5206 should equivalent to release 6.22 of NuttX 6.22:
|
|
|
|
svn checkout -r5206 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
|
|
|
|
Or
|
|
|
|
svn checkout -r5206 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
|
|
|
|
Additional new features and extended functionality:
|
|
|
|
* RTOS: Application entry point is no longer user_start, but can be
|
|
configured using CONFIG_INIT_ENTRYPOINT. NuttX now supports two work
|
|
queues: A lower priority work queue (for extended processing) and a
|
|
higher priority work queue (for quick, high priority operations).
|
|
|
|
* Memory Management: Added a new granule-based allocated that can be
|
|
used to manage, aligned and quantized DMA memory.
|
|
|
|
* File System: Add hooks to allocate I/O memory with and external
|
|
allocated (need if required by DMA).
|
|
|
|
* Networking: ENC28J60 driver is (finally) verified.
|
|
|
|
* Drivers: Add hooks USB device drivers to allocate I/O memory with and
|
|
external allocated (need if required by DMA). Driver for the Windbond
|
|
SPI FLASH family (W25x16, W25x32, W25x64, and others). ADS7843E driver
|
|
extended for TSC2046 and XPT2046 and verified.
|
|
|
|
* ARMv7-M: Added logic to reset the MCU using the NVIC.
|
|
|
|
* STM32: Add support for STM32F103VET6.
|
|
|
|
* STM32 Drivers: Add logic to re-initialize UARTs a second time to
|
|
enable DMA (Mike Smith). I2C driver error recovery (Mike Smith).
|
|
|
|
* STM32 boards: Support for USB host added add to several configurations
|
|
(or at least explained in README files). Support for the Shenzhou
|
|
STM32F107 board (see www.armjishu.com). Support for M3 Wildfire
|
|
STM32F103 board (v2 and v3).
|
|
|
|
* Build System: Kconfig string de-quoting logic. Remove comments from
|
|
defconfig files (Kate). Add tool to create NuttX-style symbol tables.
|
|
Numerous changes to configuration logic as needed for the new mconf-based
|
|
configuration (much of this from Richard Cochran). Refactor common
|
|
Make.defs logic into tools/Config.mk (Richard Cochran).
|
|
|
|
* Library: Configurable terse output from strerror(). Added perror() (Kate).
|
|
Add %n format to sscanf() (Kate).
|
|
|
|
* Applications: Numerous changes and extensions to the old uIP web server
|
|
(from Kate and Max Holtzberg, see the ChangeLog for specific extensions).
|
|
UDP network discovery utility (Max Holtzberg). Embeddable Lightweight
|
|
XML-RPC Server (http://www.drdobbs.com/web-development/an-embeddable-lightweight-xml-rpc-server/184405364, Max Holtzberg).
|
|
|
|
Bugfixes (see the change log for details). Some of these are very important
|
|
(marked *critical*):
|
|
|
|
* RTOS: Fixes to priority inheritance logic (*critical*). waitpid()
|
|
critical section. Assertion in work_cancel() (Mike Smith). mmap() (Kate).
|
|
|
|
* FAT File System: Improper Boolean expression caused un-necessary writes
|
|
and performance issues (*critical*, Ronen Vainish).
|
|
|
|
* Networking: Remove an un-necessary delay from recvfrom(). This greatly
|
|
improves network performance (*critical*, Max Holtzberg).
|
|
|
|
* Graphics: NX parameter checking errors.
|
|
|
|
* Drivers: Fix double release of memory in SDIO-based, MMC/SD driver
|
|
(Ronen Vainish).
|
|
|
|
* LPC17xx: Ethernet driver fixes needed for certain PHYs (Kate).
|
|
|
|
* AVR: Fix build error (Richard Cochran).
|
|
|
|
* STM32: USB OTG FS host driver NAKing an retries. Power management
|
|
compilation errors (Diego Sanchez). Missing SPI3 remap logic.
|
|
|
|
* STM32 Drivers: Fix for Ethernet errata for STM32F107 (*critical*).
|
|
Ethernet buffer alignment check. Add "kludge" to Ethernet driver to
|
|
handle DM9161 PHY which (at least on the Shenzhou board), sometimes
|
|
does not come up correctly.
|
|
|
|
* Applications: THTTPD (Kate). NSH ping when IP address is on a different
|
|
network (Darcy Gong).
|
|
|
|
* Library: fread(), fflush(), fdopen(): Fix error handling logic (Ronen
|
|
Vainish). Fix some field-width handling issues in sscanf()
|
|
|
|
As well as other, less critical bugs (see the ChangeLog for details)
