+NuttX-6.31
+----------
+
+The 98th release of NuttX, Version 6.31, was made on October 28, 2013,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.31.tar.gz and
+apps-6.31.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+ * General:
+
+ - Standardized stack checking logic so the interfaces can be used
+ by common stack monitoring logic.
+
+ * Audio Subsystem and Audio Drivers:
+
+ - Ken Pettit has finally released his long awaited audio subsystem.
+ This is a generic audio subsystem that is appropriate for the
+ deeply embedded MCU. Current testing has, however, been focused
+ on the VS1053 CODEC chip.
+ - Ken Pettit's VS1053 audio CODEC driver is now functional.
+
+ * Networking / Network Drivers
+
+ - Add the prefix ETH0 to all PHY configuration selections. This
+ will allow us to support to Ethernet MAC drivers with two different
+ PHYs (identified with ETH0 and ETH1). Enabled with CONFIG_NETDEV_MULTINIC.
+ - Add MII/RMII PHY definitions for the Micrel KSZ8051 PHY.
+ - Add GMII/GRMII PHY definitions for the Micrel KSZ9021/31 PHY.
+ - New network-optimized, higher-performance sendfile() implementation
+ from Max Holtzberg.
+ - Added a simple routing table. This table is currenly only used (1)
+ when we need to look-up an Ethernet device based on an IP address,
+ and (2) in the ARP logic when we need to request the MAC address of
+ the router, vs the MAC address of the peer.
+ - Make net_close() nonblocking and free unestablished connections if
+ no free connections available. From Max Holtzberg.
+ - Changed the meaning of the uip_*input functions. They now return
+ success when a packet is dropped; This is needed for the ENCX24J600
+ driver that must make a decision to return the packet or not: It
+ should not retry dropped packets. From Max Holtzberg.
+ - David Sidrane has completed integration of the CC3000 networking.
+ This is much more than a network driver: It is a complete
+ replacement for the NuttX networking with off-chip networking support
+ in the CC3000.
+ - Numerous enhancements to the ENCX24J600 driver from Max Holtberg.
+
+ * Other Common Drivers:
+
+ - The SST25 serial FLASH MTD driver now includes support for the
+ SST25VF016B. From David Sidrane.
+ - Add a preflight method to the SDIO interface to support the STM32
+ DMA usage model. From Mike Smith.
+ - Enhanced the MMC/SD SDIO driver to perform DMA preflight operations
+ and fail DMA read/write requests that fail preflighting. From Mike
+ Smith.
+ - Add an ioctl command that can be used to trigger ADC/DAC conversion
+ under application control.
+
+ * File Systems:
+
+ - Enhanced the FAT32 filesystem code to understand DMA preflight
+ failures, and to use the file sector buffer as a bounce buffer when
+ a user-supplied buffer is not suitable for DMA. From Mike Smith.
+
+ * Atmel AT91 SAMA5D3x
+
+ - Add support so that subsets of the total DRAM (and other external
+ memory) can be added to the heap, leaving other memory reserved for
+ other purposes (like the LCDC framebuffers).
+
+ * Atmel AT91 SAMA5D3x Drivers:
+
+ - Use more descriptive task names when starting the EHCI and OHCI
+ monitor tasks.
+ - Added a 10/100Base-T Ethernet (EMAC) driver.
+ - Added a 1000Base-T Ethernet (GMAC) driver.
+ - Added a Real Time Clock (RTC) driver and integrated with the NuttX
+ system time logic.
+ - Added support for /dev/random using the SAMA5D3x True Random Number
+ Generator (TRNG).
+ - Added a Watchdog Timer (WDT) driver.
+ - Added a Timer/Counter (TC) library with interface that make be used
+ by other drivers that need timer support.
+ - Added an ADC driver that can collect multiple samples using the
+ sequencer, can be trigger by a timer/counter, and supports DMA data
+ transfers.
+ - Added a touchscreen driver based on the special features of the
+ SAMA5D3 ADC peripheral.
+ - Added an LCD controller (LCDC) frame buffer driver.
+ - Added a CAN driver. However, testing has been delayed because of
+ cabling issues.
+ - Basic header file support is available for the Image Sensor
+ Interface (ISI) camera interface. Work on the camera driver is
+ underway and is expected in the next release.
+
+ * Atmel AT91 SAMA5D3x-EK Development Boards
+
+ - Add OS test support for the FPU test.
+ - Enable the task name feature board configuration sto provide
+ prettier ps command output.
+ - Added NX and NxWM configurations to verify the LCD and touchscreen.
+ There are still some outstanding issues with the NxWM configuration
+ as of this release.
+ - The TRNG and /dev/random are now enabled by default in the demo
+ configuration.
+
+ * Atmel AT91 SAM3/4 Boards:
+
+ - Add configuration to select revision 3 of the Arduino Due which has
+ some small but important differences. Suggested by gdi@embedders.org.
+
+ * STMicro STM32:
+
+ - Add support for the STM32F207ZE chip. From Martin Lederhilger.
+
+ * STMicro STM32 Boards:
+
+ - Add configuration for the Spark Core. The initial check-in is
+ basically the Maple Mini board and subsequent development by David
+ Sidrane is his special Spark emulation hardware. The configuration
+ should be very mature when actual Spark hardware is available.
+ - Support for the Olimex STM32 P207 board added by Martin Lederhilger.
+ - Configuration for the Mikroe STM32F4 board configuration updated for
+ audio support by Ken Pettit.
+
+ * NXP LPC17xx Boards:
+
+ - zkit-arm-1769: LED1 is now user controllable after booting. From
+ Rashid Fatah.
+
+ * Kinetis KL Drivers:
+
+ - PIT and TPM register definitions header files for the from Alan
+ Carvalho de Assis.
+ - Added low-level getc() function for operation with no file system.
+ The KL25Z can now support NSH in a very minimal system that does
+ not even have a file system.
+
+ * Kinetis KL Boards
+
+ - A new configuration called minnsh was added is an experiement to
+ see how small we can get the NuttX footprint and still support NSH.
+ From Alan Carvalho de Assis..
+
+ * TI Calypso Phones:
+
+ - Basic board support for the Motorola C139 (Compal E86) phone. From
+ Craig Comstock.
+
+ * Applications:
+
+ - Moved several useful examples from apps/examples to apps/system.
+ This includes USB MSC, USB CDC/ACM, and USB Composite.
+ - New addroute and delroute commands added to NSH in order to manage
+ the network routing table.
+ - Numerous enhancements and updates to the CC3000 example from David
+ Sidrane.
+ - Add a new stack monitor daemon that can be used to constantly
+ monitor stack usage by all threads.
+ - Numerous changes to get NSH working with no file system. Basically
+ this suppresses I/O redirection and replaces file I/O with calls to
+ low-level console read/write functions. Suggested by Alan Carvalho
+ de Assis.
+ - apps/system/nxplayer: A new, command-line media player called
+ 'nxplayer' from Ken Pettit.
+ - apps/examples/random: Add a simple test that dumps values from
+ /dev/random.
+ - apps/examples/adc: Add support so that a ADC driven by software
+ triggering can be tested.
+
+ * Build System:
+
+ - The MKDEP tools now support a new argument that identifies the
+ object file path.
+
+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 48% of the configurations have been converted
+ to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+ * Initialzation and Scheduling:
+
+ - IDLE thread initialization logic should not call group_setupidlefiles()
+ if there are no file descriptors (and, hence, no file system).
+ - Fix some cornercase error handling logic: If sched_releasetcb() is
+ called as part of a failed pthread startup before the flags field in
+ the TCB has been initialized, then a crash occurs. Pointed out by
+ David Sidrane.
+
+ * Networking / Network Drivers:
+
+ - Look up of a device using subnet will fail if the packet is being
+ sent out of our subnet (via a router). The fallback here is just to
+ use the only device ("eth0") if the subnet lookup fails (this logic
+ was extended to handle multiple Ethernet devices by adding a simple
+ routing table).
+ - Fix some backward conditional logic in send() that enabled the
+ check if the ARP address is in the ARP table. From Max Holtzberg.
+ - Notify the socket layer from the network monitor if a connection is
+ lost before the monitoring callback has been registered. From Max
+ Holtzberg.
+ - send(): Reset the send timeout when the data is ACKed, not when the
+ data is sent. Remove conditions on checking for timeout. From Max
+ Holtzberg.
+ - Correct how the TCP/IP initial minimum MSS is calculated. Max
+ Holtzberg.
+ - TCP state machine: Move tcp connection into SYN_RCVD state after
+ aception instead of bypassing and moving directly into ESTABLISHED.
+ From Max Holtzberg.
+ - Numerous fixes to the ENCX24J600 driver from Max Holtberg.
+
+ * USB Drivers:
+
+ - Change naming of SELFPOWERED and REMOTEWAKEUP to avoid name
+ collisions. Prepend the name of the driver (for example
+ CDCACM_SELFPOWERED).
+ - CDC/ACM class driver: Change the interval for the interrupt
+ endpoint from 0xff (invalid) to 10. This is not a critical
+ change but will avoid a complaint from the Linux driver when
+ it overrides the 0xff value.
+
+ * ARM Cortex-A5:
+
+ - Fix an error in data cache clean and invalidate functions: Fix of
+ addresses to cache line boundaries.
+
+ * Atmel AT91 SAMA5D3x Drivers:
+
+ - Correct some inconsistencies in the way that USB configuration
+ settings are used. This caused compilation errors in SAMA5 OHCI
+ when USB debug was ON but USB host tracing was off.
+ - When 480MHz UPLL is used to drive OHCI, it should have a divider
+ of 10. However, that does not work. A divider of 5 does. Why?.
+ - OHCI HCD: Fix a place where DMA-related data needed to be flushed
+ to data cache; Fix another where a virtual address was being used
+ in a register where a physical address was required.
+ - HSMCI Driver: TX DMA disabled. It is just not reliable. No idea
+ why. RX DMA is still used.
+ - STM32F103C pinmapping corrections from David Sidrane.
+
+ * Atmel SAMA5D3x-EK Board
+
+ - Increase the number of pre-allocated watchdog timers. The default
+ number of 4 was easily being exhausted in the more complex
+ configurations.
+
+ * STMicro STM32:
+
+ - STM32 F4 DMA definitions: Typo fixes for UART7 and UART8 DMA
+ configs. From Mike Smith.
+ - DMA priority configuration corrections from Mike Smith.
+ - Changes to the stm32_dmacapable API. In order to correctly
+ verify that a buffer can be transferred, the transfer count and
+ the CCR value are required. Implemented stm32_dmacapable for
+ stm32f1xx devices. Enhanced stm32_dmacapable for stm32f2xx and
+ stm32f4xx devices to check for additional conditions that will cause
+ DMA to fail or lose data.
+ - STM32 F1 DMA fix from David Sidrane: The DMA_CNDTRx register
+ cannot be modified if the DMA channel is disabled.
+
+ * STMicro STM32 Drivers:
+
+ - Fix compilation errors from bad bit definitions in ADC and PWM
+ register. From Martin Lederhilger.
+ - DMA-related fixes to the SPI driver from Ken Pettit.
+
+ * NXP LPC17xx Drivers:
+
+ - Remove undefined spi_select() prototype. This was causing compile
+ time warnings.
+
+ * NXP LPC17xx Boards:
+
+ - zkit-arm-1768: MMC/SD is on SPI, not SSP0. From Rashid Fatah.
+
+ * C Library
+
+ - scanf() fixes from kfrolov: 1) sscanf() function hangs in the
+ following example: sscanf("2", "%u,%u,%u,%u", ...), 2) sscanf()
+ returns incorrect number of parsed numbers if some arguments
+ can't be parsed: sscanf("=2", "%u,%u,%u,%u",...)==1 instead of
+ 0, and 3) using of char* instead of const char* in vsscanf
+ function leads to warnings from GCC.
+
+ * Build System
+
+ - Dependency generation generation was broken for directories that
+ keep objects in a sub-directory. The MKDEP tools now support a new
+ argument that identifies the object file path.
+ - tools/define.sh: 'cut' no longer works as it once did. Script
+ adapted to observed behavior.
+
+ * Applications:
+
+ - Remove a warning from the NSH library when DHCP is not enabled.
+ - Default NSH IP address should be 0x0a000001 (10.0.0.1), not
+ 0xa0000001 (160.0.0.1). Ditto for the gateway.
+ - Add some missing options to the OS test Kconfig file
+ - Fix some bad conditional compilation in the USB monitor.
+ - Fix default I2C frequency used by the I2C tool: 400KHz instead
+ of 4MHz. Suggested by Max Kriegleder.
+ - Increase stack size for the system/info command. Ken Petit
+ reports that this simple command can exceed its 768 stack size
+ under certain conditions. The size is marginal and has been
+ increased to 1024 by default but is also now configurable.
+ - apps/Makefile: Needs to include external/Make.defs if we want
+ allow external applications to participate in the NuttX
+ configuration. Suggested by gdi@embedders.org.
+ - apps/netutils/telnetd: Missing argument to debug statement
+ can cause crashes in certain error conditions. From David
+ Sidrane.
+ - apps/examples/can: Correct an error in a debug statement. From
+ Martin Lederhilger.
