Some of these are very important: - telnetd Example: Naming is confused. In someplaces 'telnetd', and in others 'shell.' All changes to telnetd. Noted by Pelle Windestam. + +NuttX-7.3 +--------- + +The 103rd release of NuttX, Version 7.3, was made on June 25, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.3.tar.gz and +apps-7.3.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Dynamic loader: Framework to support Pascal P-Code as a binary + format that can be exec'ed from a file system. + - Dynamic Loader: Extend the binfmt interface to handle error + conditions where format-specific clean-up is needed in the event + of error conditions. This is needed by the P-Code binfmt. + + * Networking + + - IOB: Add a generic I/O buffer chain logic. This logic uses small, + pre-allocated buffers that can be chained together to support + transfers of any size, using fewer resources and also without + committing in advance to a TCP window size. There is now only + one I/O type used in the networking and it is these I/O buffer + chains. + - TCP Write Buffering: TCP write buffering logic converted to use + I/O buffer chains. + - TCP Read-Ahead Buffering: TCP read-ahead buffering logic converted + to use I/O buffer chains. + - Includes logic to support throttling of read-ahead buffering if + the read-ahead buffering is competing with write buffering for + I/O buffers. + - Raw Sockets: Add support for the AF_PACKET socket family. From + Daniel Lazlo Sitzer. + + * Common Drivers: + + - W25 Serial FLASH driver extended by Mark Whitehorn to support the + 8Mbit W25Q80BV part. + - Add support for Fujitsu MB85RS1MT RAMTRON part. From Charles Ash. + - Enhancements to the generic timer interface to support capture mode + from Bob Doiron. + - Add an rxflowcontrol method to the serial interface to better + support RX flow control. This involves common changes in addition to minor updates to all MCU-specific serial drivers (only fully implemented for the STM32). From Jussi Kivilinna. + + * Atmel SAM4C + + - Add support for the SAM4CM family. From Max Neklyudov. + + * Atmel SAM4E/4S Drivers: + + - RTT driver from Bob Doiron. Also added high resolution RTC + emulation using the RTT for the sub-second counter. + + * Atmel SAM4E/4S Board Support: + + - The SAM4S Xplained Pro now uses the extended timer/counter + features. From Bob Doiron. + - Added a touchscreen and LCD driver for the SAM4E-EK board (the LCD, + however, not yet fully functional). + + * Atmel SAMA5: + + - Optimized, high performance, assembly language memcpy(). This is + the same optimized memcpy() function that Mike Smith brought in + for the ARMv7-M with minor tweaks by David Sidrane to work with + the ARMv7-A. + - Basic support added for the SAMA5D4 family. + + * Atmel SAMA5 Drivers: + + - SAMA5D4: New drivers unique to the SAMA5D4: XDMAC, SAIC, and + others. + + * Atmel SAMA5 Board Support: + + - SAMA5D4-MB: Initial board support for the SAMA5D4-MB/EK boards. + + * STMicro STM32 + + - Add support for the STM32152 and STM32162 Medium+ density parts + (plus miscellaneous other improvements to the original STM32151 + logic). From Jussi Kivilinna and Sami Pelkonen. + + * STMicro STM32 Boards: + + - Support for the Olimex STM32 H405 board contributed by Martin + Lederhilger. + + * STMicro STM32 Drivers: + + - Implement the rxflowcontrol method to the serial interface to better + support RX flow control. From Jussi Kivilinna. + + * NXP LPC17xx Drivers: + + - Added support for the RTC, ADC, DAC, Timers, PWM and MCPWM + drivers. From Max (himax). + + * NXP LPC17xx Boards: + + - Support for the RTC, ADC, DAC, Timers, PWM and MCPWM integrated + in the LPCXpresso LPC1768 board support. From Max (himax). + + * Library: + + - Add support for seek-able streams. + + * Configuration/Build System: + + - Restructured network directories, header files, and naming to + better modularize the networking and to better integrate the + networking with the rest of NuttX. + + * Applications: + + - prun: An NSH built-in application that can be used to run + Pascal P-Code programs either programatically or from the NSH + command line. + - netpkt: A "raw" socket test from Lazlo Sitzer. + - hex2bin: A library and built-in task to convert from + Intel HEX to binary format. It can write the binary data to a file or it can store the binary data to memory (to support, for example, a loader). + +Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): + + * Core OS: + + - Dynamic Loader: Fix an error in a symbol table search function. + Noted by Pelle Windestam. + - Dynamic Loader: Fix a critical error in exec(); argv was not + being passed. + - mq_notify: Test for a valid signal number was inverted; this + function could not have been working correctly before??? From + eero.nurkkala. + - Fix typo in conditional compilation: CONFIG_CLOCK_MONOTONIC vs. + CLOCK_MONOTONIC. From Manuel Stühn. + + * Graphics + + - Fix typos in several RGB conversion macros. + + * Networking: + + - Modify TCP timout handling to provent situations where connections + may not be freed. From Max Holtzberg. + - Improved TCP fallback allocation logic from Max Holtzberg. Also, + fallback mechanism is disabled when SO_LINGER is to prevent + deadlocks. + - Write Buffering: Add checks from buffer allocation failures. From + Max/Himax. + + * Network Utilities: + + - webserver: httpd_fs_open() should return OK on success and ERROR on + failure, not 1 and 0. + + * Common Drivers: + + - Make sure that all references to up_prioritize_irq() are + conditioned on CONFIG_ARCH_IRQPRIO. Problem noted by Mike Smith. + - CC3000: Correct SPI mode for CC3000 is CPOL=0 CHPA=1. From Jussi + Kivilinna. + - CC3000: Fix a race condition in thread start-up logic. From Jussi + Kivilinna. + - CC3000: Additional fixes including a compilation failure if POLL is + enabled. From Jussi Kivilinna. + + * USB Drivers: + + - CDC/ACM and PL2303 device: Reset RX head to avoid resending last + serial data when USB cable disconnected/re-connected. From + Lizhuoyi. + + * TI Tiva/Stellaris Boards: + + - The Nucleo-F401RE has no on-board crystals and, hence, needs to run + with the PLL input from the on-chip HSI clock. + + * STMicro STM32 Drivers: + + - Serial: Handle configuration for the case of 8-bit data with + parity. From Freddie Chopin. + + * Atmel SAM3/4 Boards: + + - There was a cloned error in all SAM3/4 board configurations (and + for a few other architectures as well). Button interrupts not + being disabled after being detached. As a result, unexpected + interrupts could be received after the button interrupt was + detached. + + * Atmel SAMA5: + + - Fix some critical typos in the SAMA5D3 DMA definitions. + + * STMicro STM32 Drivers + + - I2C: Add an alternative I2C implementation for the STM32 F103 that + works around errata in that specific part. From Patrizio Simona. + - RTCC: Add retry logic to RTC initialization. It sometimes takes + longer for the RTC to initialize, at least as noted on an F2 part. + From Daniel Lazlo Sitzer. + + * NXP LPC17xx Drivers + + - GPDMA: Fix an error when DMA is started: The read-modify-write + fails when the DMA is started. This is because the value read is + not the same as the value set (on write it is the number of + transfers to do; on read it is the number of transfers completed). + From Lizhuoyi. + + * Library: + + - snprintf(): If the size passed to snprintf() is zero, then + snprintf() must write nothing, but instead return the size of the + buffer needed to hold the entire string. From Sami Pelkonen. + + * Configuration/Build System: + + - The alternate console device CONFIG_NSH_CONDEV must not be defined + unconditionally. This causes errors when using Telnet sessions. + This was solved by adding CONFIG_NSH_ALTCONDEV: CONFIG_NSH_ALTCONDEV enables or disables the feature then, if + enabled, CONFIG_NSH_CONDEV provides the alternative console + device name. + - Many files: Convert all old-style GCC variadic macros to the C99 + form. Recent GCC changes tightens up that behavior and can cause + some problems (at least for the IAR compiler for some reason). + Noted by Bob Grimes. + - tools/configure.sh: In-place SED edit messes up permissions on + windows. From Hannes Delago. + + * Build Tools: + + - tools/mkfsdata.pl: Apparently, the trailing the 0x00 in http + server files is seen as a bug in javascript and images. From + Max/Himax. + + * Other Applications: + + - I2C Tool: Fix to show the updated register address on each + fetch (vs. showing the same starting address each time). From + Ryan VanSickle. + - CLE was not returning the terminating newline character. But + reported by Max kriegleder. |
