Some of these are very important: from C code. - Add some missing NSH library configuration values (from Lorenz Meier). + +NuttX-6.29 +---------- + +The 96th release of NuttX, Version 6.29, was made on July 31, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.29.tar.gz and +apps-6.29.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Drivers: + + - Generalized the SSD1306 driver and added support UG-2832HSWEG04 + which is very similar to the existing support for the + UG-2864HSWEG01. + - Added support for a generic bit-bang SPI driver. This includes + both a common "upper half" driver as well as a platformp-specific + "lower half" dirvers based on a common "template." + + * ARMv7-A, Cortex-A5 + + - Added support for the ARMv7-A architecture and the Cortex-A5 in particular. + + * ARMv7-M, Cortex-M3/4 + + - Modified how some registers are copied during a context switch (with + lazy FPU register saving). This should save some context switching + time when the context switch is due to interrupt level processing. + + * STM32: + + - Added support for a separate CCM heap. This may be useful for + segregating allocations for CCM (which cannot be used for DMA) + from other allocations (that may be used used for DMA). + + * STM32 Drivers: + + - DAC: Added support for DAC DMA (contributed by John Wharington). + - I2C: An I2C driver for the STM32 F3 family (from John Wharington). + + * Atmel AT91 SAM/4: + + - Add support for SAM3X and SAM3A chips + + * Atmel AT91 SAM/4 Drivers: + + - Re-architect the SAM3/4 SPI driver so that is it compatible with the + SPI drivers of other MCUs. + - Added register definition file for the SAM4L LCD peripheral. + - Added SAM4L PDCA register definition file + + * Atmel AT91 SAM/4 Boards: + + - SAM4L-Xplained: Added support for the SPI-based SD card on the I/O1 + module. + - SAM4L-Xplained: Added a driver for the LED1 segment LCD module. + - SAM4L-Xplained: Added support for the UG-2832HSWEG04 OLED on the + SAM4L Xplained Pro's OLED1 module + - SAM4S-Xplained: Added support for on-board 1MB SRAM + - Arduino Due: Basic support for the Arduino Due (SAM3X) is now + included. + - SAM3U-EK: The touchscreen is now functional. + + * Atmel AT91 SAMA5D3 + + - Added support for the Atmel AT91SAMA5D3 Cortex-A5 chip family. + + * Atmel AT91 SAMA5D3 Boards + + - Added support for the Atmel SAMA5D3x-EK boards which use the AT9 + SAMA5D3x chips (x=1,3,4,5). + + * Freescale KL25Z Drivers + + - Freescale KL25Z TSI register definitions and example TSI driver for + the Freedom KL25Z board from Alan Carvalho de Assis. + - Added SPI driver and register definitions for the Freescale KL25Z. + - Added a framework for controlling SPI-related discrete inputs and + outputs. Taken from work by Alan Carvalho de Assis + + * Build System: + + - New sub-directories to hold SPI-related files: includes/nuttx/spi.h + moved to include/nuttx/spi/.; SPI-related Kconfig info moved from + drivers/Kconfig to drivers/spi/kconfig. + - Finally... I changed the naming of configuration variables like + CONFIG_DRAM_ to CONFIG_RAM_. This has bothered me for a long time + since most boards don't have DRAM. The more generic RAM naming + should not produce so much cognitive dissonance + + * Libraries: + + - Added CRC16 support. + + * Applications: + + - Added Zmodem file transfer support. This may be used as an embedded + library or may be built as 'sz' and 'rz' commands that can be + executed from NSH. + - C++ initializers should be set once and, preferably, in the context + of the task that uses any C++ statically initialized classes. This + only becomes an issue if cxxtest or helloxx are built as NSH builtin + applications. Then you want the initialization done in cxxtext or + helloxx and not in NSH (and certainly not twice). Added + configuration options to control who does the C++ initialization. + NSH now does not do C++ initialization be default and must be + configured to do otherwise. Conversely, cxxtest and helloxx + will always do C++ initialization unless configured do otherwise. + - examples/cxxtext: Add ostream test as provided by Michael. + - NSH: Added a 'cmp' command that can be used to compare two files + for equivalence. Returns an indication if the files differ. + Contributed by Andrew Tridgell (via Lorenz Meier). + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely be be +completed soon. + + * Audio System: + + - A complete audio subsystem include CODECs, higher level management, + interface definitions, and audio drivers was contributed by Ken + Pettit. This work has not been completely verified as of this + release and so is categorized as a work-in-progress. At present, + progress is blocked due to issues interfacing with the VS1053 + audio DAC on the Mikroe STM32F4 board. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 45% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * File Systems: + + - Fixed compilation error if no file systems are enabled: Change + error to ERROR. + - Read-Ahead/Write buffering: Correct typos that can cause failures + in some configurations (From Chia Cheng Tsao). + + * Drivers + + - Remove the wait for the touchscreen busy bit in the ADS7843E driver. + From my reading of the ADS7843 spec, it would not be appropriate to + wait for the BUSY bit to de-asserted anyway (since it is only de- + asserted when we read the data). Most boards do not even bother to + provide the BUSY bit. + - MMC/SD SPI based driver: Driver needs to make sure that the SPI + mode and data width are correct. + - ENC28J60: Change buffer ordering to work around Errata. From Dave + (ziggurat29). + + * USB Device Controller Drivers: + + - Fixed a typo in the composite device driver unitialization logic. + DEV1 should be DEV2 in one case. + - usbdev.h: Fix some typos that cause compiler errors when + CONFIG_USBDEV_DMA and CONFIG_USBDEV_DMAMEMORY are selected (From + Chia Cheng Tsao). + + * ARM9: + + - Fix a bug (uninitialized register error) that crept in the ARM9 + boot-up code several years ago. Obviously no one has used the + ARM9 NuttX port for years! + + * STM32 Drivers: + + - Fix STM32 OTF FS endpoint allocation logic. Apparently the same + endpoint can be allocated as both an IN or an OUT endpoint. The + existing implementation only supported one allocation, either IN or + OUT. This resulted in failures to allocate endpoints when used with + the CDC/ACM + MSC composite driver (From Chia Cheng Tsao). + - SDIO: Add support for the data block end (DBCKEND) interrupt to + terminate transfers (From Chia Cheng Tsao). + - DAC: Fixed numerous DAC driver errors and added support for DAC + DMA (contributed by John Wharington). + + * SAM3/4: + + - SAM4S: Correct configuration of PIO pins for SAM4S B and C peripherals. + - Need to disable write protection before configuring PIO pins. + - GPIO configuration logic must protect against re-entrancy. + - Clocking must be applied to the SMC module for the 3X and 3A family in + order for the NFC SRAM to be functional. + - Fixed some errors for interrupts on ports D-F. + + * SAM3/4 Drivers: + + - Common SPI driver: Fix SPI mode setting. In the SAM3/4 family, the + clock phase control (CPHA) is inverted (NPHA). Also fixed an + incorrect pointer test. Was checking if the wrong pointer was NULL. + + * SAM3/4 Boards: + + - SAM3U-EK: Fix polarity of the /PENIRQ signal (it is active low). + The SAM3U-EK board now runs at 96MHz. + + * Applications: + + - apps/examples/nxhello: Minor fix for compilation error when the + display resolution is low (< 8bpp) due to a typo that has been there + for a long time. Also Correct default colors when in Y1 code mode. + - apps/system/ramtest: The RAM test was not correctly built + into the configuration and build system. + - apps/examples/composite: Change to prevent some false alarm debug + assertions (From Chia Cheng Tao). |
