| 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) |
