The + Spark configuration includes integrated CC3000 wireless support, FAT + file system on the SerialFlash and a composite device that can be + used both to export the FAT file system and to provide a serial + interface. + - The Mikroe-stm32f4 now uses /dev/config for configuration data + storage. From Ken Pettit. + - Added support for the STM32F429I-Discovery board from Ken Pettit. + - Added board support for the ViewTool STM32F103/F107 board with the + STM32F107VCT6 installed. + + * NXP LPC31xx Drivers: + + - USB ECHI HCD: Add a driver for the low-/full-/high-speed variant + of the EHCI host controller. + + * NXP LPC31xx Boards: + + - Board-specific USB host support for the Emedded Artists EA3131 board. + (Missing PCA9532 controls). + - Add support for the Olimex LPC-H3131 board. Including USB host + support (which does not depend on the PCA8532 interface). + + * Kinetis KL Drivers: + + - PWM driver for the Freescale Kinetis KL family from Alan Carvalho + de Assis. + + * Kinetis KL Boards + + - Freedom-KL25Z: Add PWM support from Alan Carvalho de Assis. + + * TI Stellaris LM3S + + - Don't initialize .data in start-up logic if not running from FLASH. + + * Applications: + + - apps/platform: A new home for platform-specific application code. + - Define a common interface that can be used to manage platform- + specific configuration data. From Ken Pettit. + - apps/examples/configdata: A unit test for the MTD configuration + data driver from Ken Pettit. + - Aapps/platform/mikroe-stm32f4: dd platform-specific storage of + configuration data for the Mikroe-stm32f4. From Ken Pettit. + - apps/examples/cc3000: Fine tuning of memory usage from David Sidrane. + - apps/system/nxplayer: Play thread stack size is now configurable. + All NxPlayer threads now have names assigned via pthread_setname_np(). + From Ken Pettit. + - apps/examples/i2schar: The I2S test based on the I2S character + driver. + - apps/examples/hidkbd/hidkbd_main.c: Now calls a function named + arch_usbhost_initialize() that must be provided by the platform- + specific code. + - NSH: + + - hexdump: Add skip= and count= options to the hexdump command. From Ken Pettit. + - Allow USB trace without a USB console. From David Sidrane. + - Mount command updates from Ken Pettit. + - Add an option to the mkfatfs command to specify FAT12, FAT16, or FAT32. + + * Tools + + - tools/mkctags.sh: A script for creating ctags from Ken Pettit. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely be be +completed soon. + + * 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 50% 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 + + - FAT: In one error return case, the error return value was not being + set, making the failure look like success. From David Sidrane. + - mount: SMART FS must be included in the conditional compilation for + the set of file systems that require block drivers. From Daniel + Palmer. + - SmartFS: Fixed a minor bug with SMART partition number reporting + that would only be seen if both partition support and multi-root + directory support are enabled at the same time. From Ken Pettit. + - Deadlock: The inode semaphore must be re-entrant. Here is the re- + entrant path that I found: (1) USB host connects to FLASH drive and + creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is + removed but /dev/sda is not destroyed because there is still a + reference on the device because of the mount, (4) umount() is + called, taking the inode semaphore, now the driver tries to destroy + the block driver by calling unregister_blockdriver(). But (5) + unregister_blockdriver() also takes the inode semaphore causing a + deadlock if the inode semaphore is not re-entrant. + - FAT: Fix a typo in the FAT16 formatting logic. Was this ever able to + format a FAT16 volume? + + * MTD Drivers + + - MTD Partitions: Fix erase block vs page block confusion. From Ken + Pettit + - SST25 Serial Flash: Improved write performance by fixing a bug that + prevented operation in the faster write mode. From David Sidrane. + + * USB Drivers: + + - USB MSC Device: pthread_join() does not work if called from a + different task group than the pthread. This is correct behavior, + but still a problem. The correct solution would be configure the + USB MSC thread to a task, however, this workaround from David + Sidrane plugs the hole for now. + - USB CDC/ACM, USB MSC, and Composite Device Classes: Un-initialization + logic caused re-use of a stale pointer. Changed to a two pass + un-initialization for the case of the composite driver: Memory + resources are not freed until the second un-initialization pass. + From David Sidrane. + + * STMicro STM32 Drivers: + + - STM32 F1 USB Device: Fix some errors that cause crashes when the USB + was disconnected. From David Sidrane. + - STM32 F1 USB Device: Correct EP0 state handling logic when buffers + larger than the EP0 packet size are sent. From David Sidrane. + - STM32 F1 USB Device: The long outstanding bug involving the handling + of OUT SETUP commands has been fixed in the STM32 F1 USB device + driver by David Sidrane. + - Kconfig: Add missing setup of CAN TSEG1 and TSEG2 values. From + Martin Lederhilger. + + * Tools + + - tools/mkconfig.c: SMART FS must be included in the conditional + compilation for the set of writable file systems. Noted by Daniel + Palmer. + + * Applications: + + - apps/platform/Makefile: Was not dealing with the bin sub-directory + correctly. + - apps/system/composite/composite_main.c: The wrong handle was getting + nullified.
