Some of these are very important: - OS test: Fix timing error in non-cancelable thread test. - NSH: Correct the test of the skip input parameter. Was limiting the range to <= count. From Ken Petit. + +NuttX-6.28 +---------- + +The 95th release of NuttX, Version 6.28, was made on June 14, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.28.tar.gz and +apps-6.28.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * File Systems: + + - SMART FLASH file system (contributed by Add Ken Pettit). + + * MTD (FLASH) Drivers: + + - Add support of MTD partitions via a new MTD driver that manages a + set of MTD devices, each managing a subset of the FLASH region + managed by the parent MTD driver. + - Extended the MTD interface to provide an (optional) method to + perform byte oriented writes if supported by the FLASH part. + - M25Px driver re-architected to use the byte write capability (when + possible) and to use 4KB sectors for the erase block size when the + part supports it (from Ken Pettit). + + * LCD Drivers: + + - New interface definitions to support audio devices (from Ken Pettit) + and alphanumeric, segment LCDs. + + * Wireless Drivers: + + - Added new driver for the wireless nRF24L01+ transceiver (from + Laurent Latil). + + * Calypso: + + - Added support for the Pirelli DP-L10 phone (from Craig Comstock via + Alan Alan Carvalho de Assis) + + * STM32: + + - Added an option to conditionally disable the "wfi" sleep mode. This + is needed with certain JTAG debuggers to to prevent the debug + session from begin disconnected (from Ken Pettit). + - Added support for the STM32L (STM32L15X/STM32L16x) family. + - Added STM32F103C4 and F103C8 chip support (from Laurent Latil). + - Added a new interface function, stm32_dmacapable() that can be used + to determine if DMA is possible from the specified memory address + (from Petteri Aimonen) + + * STM32 Drivers: + + - If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses + stm32_dmacapable() to determine if it is possible to perform DMA + from the specified address. This change is important for the STM32 + F4 which may have SPI data buffers allocated on the stack in CCM + memory which cannot support the DMA (from Petteri Aimonen). + + * STM32 Boards: + + - Support added for the MikroElektronika Mikromedia for STM32F4 + development board (from Ken Pettit) with the MIO283QT2 LCD and + touchscreen. Several graphics configurations are included. + - The HY-mini STM32v board now uses the common SSD1289 driver + and supported the card detect interrupt. Several new + configurations also added and some removed (from Laurent Latil). + - Support added for the R65105-based LCD that comes with some + HY-Mini STM32v boards (from Christian Faure). + - Added basic support for the STM32L-Discovery board. Drivers + for the on-board segment LCD are included. + - Added support for the STM32 Tiny development board based on the + STM32 F103C8T6 MCU. This includes support for the nRF24L01+ + wireless on the board (from Laurent Latil). + + * Stellaris LM3S/LM4F: + + - Support added for a TI/Stellaris internal FLASH MTD driver (from Max + Holtzberg). + + * Stellaris LM4F Boards: + + - The LM3S6965-EK now has configurations for the UDP discovery tool and + for the TCP echo server (both from Max Holtzberg) + + * Atmel ATSAM3/4: + + - Reorganized, renamed, and updated directory structure to better + support additional members of the SAM3/4 family. + - Added support for both the ATSAM4S and ATSAM4L families. The + ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a + different beast, really much more akin to the AVR32s SoCs but + with a Cortex-M4. + + * Atmel ATSAM3/4 Boards: + + - Added support for the Atmel SAM4L Xplained Pro development board. + This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH + + 32KB SRAM). + - Added support for the Atmel SAM4S Xplained developement board. This + board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB + SRAM). + + * PIC32MX Boards: + + - Added support for the 1602 segment LCD on-board the Sure PIC32MX + board. This board will now also support a USB NuttX console and + the USB monitor test program. + + * Build System: + + - Clean-up of almost all .gitignore files: Made scope of ignore to be + only the current directory; Ignore .dSYM files in directories where + .exe's may be built. Also, in Makefiles, clean .dSYM files in + directories where an .exe may be built. + - Standardize and consolidated all build-as-an-NSH-application + configuration settings. Now only CONFIG_NSH_BUILTIN_APPS is + sufficient to build an application, test, or or example as an NSH + builtin application. + - Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI + toolchains. + + * Libraries: + + - Added encoder/decoder logic to marshal and serialize special segment + LCD (SLCD) commands intermixed with normal ASCII data. This is the + similar to the encoding/decoding logic that is used to marshal + special commands from a keyboard. + - Add dprintf() and vdprintf() (the latter from Andrew Tridgell). + - Add an application that may be built as an NSH builtin command that + will erase FLASH using a flash_eraseall NSH command (from Ken Pettit). + + * Applications: + + - Added an MTD partition test/examples. Currently used with (1) the a + simulation configuration to test MTD partitions on a RAM emulation + of FLASH and (2) with the Mikroe STM32F4 configuration. + - Added a test/example to verify alphanumeric, segment LCDs. + - Added a simple single threaded, poll based TCP echo server based + on W. Richard Stevens UNIX Network Programming Book (from Max + Holtzberg). + - Added several tests of the SMART block driver and file system (from + Ken Pettit). + - Added a runtime configuration for the UDP discover utility (from + Max Holtzberg). + - Added an example application to demo the nRF24L01 driver (from + Laurent Latil). + - New and modified NSH commands: + Added a -h option to the df command to show the volume information + in human readable form (from Ken Petit). + Add a new mksmartfs command (from Ken Petit). + +Efforts In Progress. The following are features that are partially +implemented but present in this release. Most are expected to be fully +available in NuttX 6.28. + + * 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 43% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - Modify assertion in the priority inheritance logic that is reported + to cause false alarm assertions. + + * Kernel Build: + + - Typo in syscall proxying logic corrected by Ken Pettit. + + * Networking: + + - Poll setup/teardown logic should ignore invalid (i.e., negative) + file descriptors (from Max Holtzberg). + - When readahead data is available, the network poll() logic should + set POLLIN (or POLLRDNORM), not POLLOUT (from Max Holtzberg). + + * LCD Drivers: + + - Correct power controls in the MIO283QT2 LCD driver. + + * USB Device Controller Drivers: + + - Change the default IN request buffer size from 64 to 96. This will + avoid requests of exactly MAXPACKET size and, hence, avoid so many + NULL packets. Also, fix the OUT request buffers size to exactly the + max packet size. It really cannot be any other size. + + * STM32 Drivers: + + - Correct some bad STM32 F1 DMA definitions that crept into the system + a few months ago a broke STM32 F1 DMA (from Laurent Latil) + - Fixed an error in NULL packet handling in the STM32 F1 USB device + controller driver: If the NULL-packet needed flag ever got set, + then it was not being cleared and infinite NULL packets resulted. + This only affects the CDC/ACM class and was the cause of the + failures using the USB CDC/ACM device as a NuttX console. With this + change the USB works well as an alternative NuttX console device for + the STM32 F1 family. + - Correct some bad condition compilation in the RCC logic (CONFIG_ + missing from setting names). This affects some STM32 FLASH pre- + fetch settings (from Lorenz Meier). + - Change for hardware flow control support for STM32. The change also + fixes incorrect operation of USART2 and UART5 in current master + (from Lorenz Meier and Mike Smith). + - Fixed a backward conditional in USB OTG FS host controller driver + that prevented detection of disconnection events (from Scott). + + * LPC17xx Drivers: + + - I2C interrupt control. Also correction for a single byte read + timeout error (from M. Kannan). + + * Freescale Kinetis: + + - Freedom KL25Z pin multiplexing and LED control corrections (from + Alan Carvalho de Assis) + + * PIC32MX: + + - Fix NULL packet handling in the PIC32 USB device driver. Without + this fix the CDC/ACM driver cannot be used reliably with the PIC32 + USB. With this change the USB works well as an alternative NuttX + console device. + + * Graphics: + + - Default priorities for NxWidget and NxWM threads should be 100, + not 50, to be consistent with other default priorities. + + * Applications: + + - Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN option from the NXTEXT + example. The test logic was bad for the case where this options is + not selected. Also, completed the empty Kconfig file. + - C++ name mangling was occurring when this example is built as an NSH + built-in application causing the entry to be undefined when called + from C code. + - Add some missing NSH library configuration values (from Lorenz + Meier). |
