Some of these are very important: - NSH: Modified the df -h logic to eliminate truncating numbers in conversion (like 7900 -> 7M). From Ken Pettit. + +NuttX-7.1 +--------- + +The 101st release of NuttX, Version 7.1, was made on March 15, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.1.tar.gz and +apps-7.1.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + + The previous NuttX version was 6.33. The NuttX minor version number is + incremented on each release, but the major version number is incremented + only when an incompatibility with previous versions is included in the + release. In this case, the legacy, manual configuration is no longer + supported by the NuttX build system beginning with NuttX 7.1. Only the + newer configurations generated by the kconfig-frontends tools will generate + viable NuttX configurations. + + All board configurations in the NuttX source tree have been converted to + use the newer configuration, but if you have some older style configurations + for you board, you will need to convert those configurations to use the + kconfig-frontends tools before taking any new code from the repository. See + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some + guidelines. + +Additional new features and extended functionality: + + * Core OS: + + - System time logic now includes logic to measure and calculate the + CPU load percentage (from David Alessio). This CPU load logic + extended to keep counts on each thread. The per-thread CPU is + now reported in the procfs under <pid>/loadavg An asynchronous, + "external" clock may be used to drive the CPU load calculations + for more accurate measurements when needed. + + * File Systems: + + - As mentioned above, the per-thread CPU load information is now + reported in the procfs under <pid>/loadavg. + - Many file system interfaces have been extended to operate on the + top-level NuttX pseudo filestem. These include rmdir, mkdir, + rename, and unlink. This capability can be disabled with + CONFIG_DISABLE_PSEUDOFS_OPERATIONS in order to keep the footprint + small. + + * Networking: + + - Numerous updates and improvements to the CC3000 driver from David + Sidrane. + + * Common Drivers: + + - Defined a mouse interface that is very similar to a touchscreen + interface, but allows reporting of all mouse buttons. Also, unlike + touchscreen drivers, mouse drivers need to report positional data + with no button is pressed so that the mouse position can drive a + cursor. + - Added support for a USB HID boot mouse device. Cursor support is + not integrated and must be provided by the application based upon + the reported mouse data. + - Support added for the MIO283QT9A LCD from Toby Duckworth. + + * Atmel SAMA4E: + + - Added complete architecture support for the Atmel AT91 SAM4E + Cortex-M4F parts. + + * Atmel SAM4E Board Support: + + - Add board support for the SAM4E-EK board. + + * Atmel SAM4E Drivers: + + - Added logic to manage the Cortex-M Cache Control block. + - Developed and integrated an Ethernet MAC driver for the SAM4E. + - Backported the SAMA5 SPI driver to the SAM3/4 architecture. The + SAMA5 version supports both multiple SPI peripherals as needed by the + SAM3A and SAM3X and also supports DMAC (but not PDC) needed by the + SAM4E. + + * Atmel SAM D20: + + - Added basic architecture support for the Atmel AT91 SAM D20 + Cortex-M0+ parts. + + * Atmel SAM D20 Board Support: + + - Added basic support for SAM D2 Xplained Pro board. Currently, the + NuttShell (NSH) works reliably over a serial port. An SPI driver + has also been developed. Work with the SAM D20 has been temporarily + stopped, however, in order to focus on the SAM4E-EK. + + * TI Tiva TMC4C123G: + + - Added architecture support for the TI Tiva TM4C123G parts. This was + merged into the existing support for the LM3S and LM4F families. + All directory, file, and function references changed from m to tiva. + + * TI Tiva TMC4C123G Board Support: + + - Added basic board support for the TM4C123G-Launchpad. As of this + release the TM4C123G-Launchpad board support is untested and likely + incomplete. + + * STMicro STM32 Boards: + + - configs/mikroe-stm32f4/src/up_mio283qt9a.c: The Mikroe STM32F4 can + now support the newer MIO283QT9A LCD. From Toby Duckworth. + - Miscellaneous changes to better support FPU on STM32F429 Discovery + from David Alessio. + + * NXP LPC2378 Drivers: + + - Incorporated I2C and SPI drivers for the LPC23xx from Lizhuoyi. + + * QEMU i486 Drivers: + + - New QEMU keyboard and VGA drivers from Lizhuoyi. + + * Documentation: + + - Added a coding standards document. See + http://www.nuttx.org/doku.php?id=documentation:codingstandard + + * Configuration/Build System: + + - A configuration option, CONFIG_DEFAULT_SMALL, was added to select + default values for configuration variables based upon whether you + want a smaller footprint or more features. This is not very useful + if you are modifying existing configurations because then the + default values do not apply. + - CONFIG_DEFAULT_SMALL has been defined on all tiny MCU configurations + so that they do not grow so rapidly when new, optional features are + added. + - The legacy, manual configuration is no longer supported by the + NuttX build system. Only the newer configurations generated by + the kconfig-frontends tools will generate viable NuttX + configurations. All board configurations in the NuttX source tree + have been converted to use the newer configuration, but if you have + some older style configurations for you board, you will need to + convert those configurations to use the kconfig-frontends tools. See + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some + guidelines. + + * Applications: + + - NSH can now use an EMACS-like command line editor. This CLE, is + really more like the traditional readline than is the default, tiny + the NuttX readline . + - The touscreen example can now be configured to work with either a + touchscreen or a mouse device. + - Several NSH commands can now be used to operate on objects in the + top-level pseudo-filesystem: rmdir, mkdir, mv, and rm. This + capability can be disabled with CONFIG_DISABLE_PSEUDOFS_OPERATIONS + in order to keep the footprint small. + - If both the CPU load feature and the procfs features are enabled, + then the NSH 'ps' command will show the CPU load used by each + thread. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Core OS: + + - task_terminate() always returned an error because the return value + was not being set correctly (from Gosha). + - nanosleep() Fix a missing call to re-enable interrupts (from Jason + Jiang). + + * File Systems: + + - Fixed an error in the FAT logic that can cause file corruption. The + error conditions are rare and only seen with very large files (from + Andrew Tridgell). This replaces a previous, partial fix for the same + problem. + - Fixed memory leaks in the NXFFS open() and stat() implementations + (from Lzyy). + - The interfaces include opendir(), readdir(), et al, were modified so + that errors will not be reported if you attempt to list a empty + pseudo-directory. + + * Networking: + + - Fix one place where the connection reference count was not being + decremented in the socket close() logic. This is really a cosmetic + change BUT when CONFIG_DEBUG_NET is enable, it will cause assertions. + - Backed out a small part of the NuttX 6.33 write buffering changed. + David G says that this causes problems in connecting to a server. + - In DHCPD, there was a place where the logic called should not call + ntohl() inappropriately; the address was already in the correct + order. How could DHCPD have worked with this bug? + + * TI Tiva/Stellaris Drivers: + + - Fixed cut'n'paste error that prevented UARTS2-7 from being used with + the LM4F120 Launchpad. + - Fixed several errors there were unmasked with UARTs > UART2 are + enabled (grom Gosha). + + * Allwinner A10 Drivers: + + - Fixed cut'n'paste error that prevented UARTS2-7 from being used with + the pcDuino. + + * NXP LPC17xx Drivers: + + - Fix an compilation error that crept into the LPC17xx USB host driver. + + * STMicro STM32 Drivers: + + - Fix cloned typo in the serial driver: FLOWCONTROL vs FLOWCONROL. + - Disable SPI before changing DPI CR1 register (from David Sidrane). + - stm32 TIM: Set the timer CCMR when selecting timer channel. From + David Sidrane. + - Fix typo in a Makefile: stm32_pwm.c not stm32_psm.c. Noted by Max + Kriegleder. + + * Library: + + - More sscanf() bug fixes from David Sidrane. + + * Header files: + + - cstdbool: Ignore _Bool8 if CONFIG_C99_BOOL8=y + + * Configuration/Build System: + + - Several changes to restore the broken native Windows build + + * NuttShell (NSH): + + - Use strncpy vs strcpy in the Telnet console logic to avoid + overruning the username and password buffers (from Bertold Van den + Bergh). + - Add a newline after printing the file in the 'cat' command. This + prevents the NSH prompt from be in the same line as the final line + of the file in the case where there is no newline at the end of the + file. |
