Unreleased changes after this release are available in SVN.
These unreleased changes are also listed here.
- Changes in this release are summarized below: + This release includes a few new features and several important bug fixes. + The new features (some still incomplete) include:
date command is now supported (if CONFIG_RTC is defined) that can be used to read and set the RTC.
+ Bugfixes, order roughly on decreasing criticality include: +
+gmtime() and gmtime_r() that could lead to errors in date calculations.
+ tv_nsec calculation that happens only config CONFIG_RTC is enabled
+ -print-libgcc-file-name to get path to libgcc.a might select the wrong libgcc.a if a GCC multilib toolchain is used

The driver now supports both CAN1 and CAN2. - * arch/arm/sim/up_lcd.c: Add a simulated LCD driver. - * configs/stm3210e-eval/nxlines: Added a configuration to build - examples/nxlines. - * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX - trapezoid drawing functions and (wide) line drawing functions. - * arch/rgmp and configs/rgmp. Yu Qiang has ported RGMP to the OMAP4430 (arm) - pandaboard and release the new RGMP 0.3 version. The main changes are: (1) - Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and - (2) Extract architecture dependent code in arch/rgmp/include and - arch/rgmp/src into corresponding x86/ and arm/ directories. - * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstik-k40: - Add a directory structure to support the port to the Kinetis KwikStik-K40. - There is no real substance in the initial check-in; only the directory - structure and skeleton files (Code complete on 8/15/11). - * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3 - directories and files to armv7-m; Change name of of all CORTEXM3 constants - to ARMV7M. This is a major namespace change needed to cleanly support the - ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M). - * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c. Fixed several - critical bugs related to signal handling initialization and for signals - the wake up tasks that are waiting to send or receive message queues. In - the first two files, errors would prevent proper allocation of signal-related - structures from interrupt handlers. In the second, there was missing - "clean-up" logic after a signal occurred, leaving the message queue in - a bad state and resulting in PANICs. All are important. (submitted by - hkwilton). - * arch/arm/src/kinetis: Added header files defining all Kinetis registers - and bit fields within all Kinetis registers. - * configs/twr-k60n512: Add support for the Kinetis K60 Tower board - (TWR-K60N512). - * drivers/can.c: Fixe a semaphore overflow problem in the CAN driver - (reported by Li Zhouy (Lzzy)). - * 8/18/2011: The basic port to the FreeScale Kinetics TWR-K60N512 board is - now functional. - * confgs/twr-k60n512: Add Kinetics TWR-K60N512 NSH configuration. - * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure - and TI ADS1255 driver developed and submitted by Li Zhouy (Lzzy)). - * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c: Add logic to - multiplex usage of the GPIO pins (contributed by Uros Platise). - * configs/twr-k60n512/nsh: Added and verified a NuttShell (NSH) - configuration for the Freescale, Kinetis TWR-K60N512 board. + * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts. + Initially check-in is just a crude port of the STM32 SDIO driver. + Much more work is needed. + * graphics/, include/nuttx/nx: Add new NX interfaces for drawing + circles -- both circular outlines and filled circles. + * graphic/nxglib/nxglib_spitline.c: Add a "fudge factor" that eliminates + some problems for rendering nearly horizontal, wide lines. Hmm... + but I suspect this fudge factor also leads to new problems rendering + very thin, nearly horizontal lines. More tuning is needed. + * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx: (1) Add + updates to the ADS1255 driver, (2) fix errors from my last merge (sorry), + (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add + LPC17xx ADC and DAC drivers. All contributed by Li Zhuoyi (Lzyy). + * tools/mkexport.sh: Extended the script that implements the top-level + 'make export' logic. The script now also finds and bundles up all of + the architecture-specific header files as well. + * drivers/arch/arm/src/stm32/stm32_i2c.c: Add a reset to the I2C + initialization logic to prevent spurious interrupts when the I2C + interrupts are enabled (submitted by Uros Platise). + * Scripts/makefiles/documents. Several adjustments, corrections and + typo fixes so that NuttX will build correctly on FreeBSD using the + ASH shell (submitted by Kurt Lidl). + * drivers/mtd/flash_eraseall.c: Add a callable function that accepts + the path to a block driver and then erases the underlying FLASH memory + (assuming that the block driver is an MTD driver wrapped in the FTL + layer). Hmmm... this is probably not the best long term solution; + flash_eraseall() should be a user-callable function that operates + one driver interfaces; not an internal, OS function that operates + on directly on block drivers. + * drivers/bch: Fixed some important bugs in the BCH driver (noted by + Li Zhuoyi (Lzyy)). This would have effected any large reads or writes + (larger than the hardware sector size). + * arch/*/src/Makefile: Use of -print-libgcc-file-name to get path to + libgcc.a may select the wrong libgcc.a if a multilib toolchain (like + CodeSourcery) is used. This can be a serious problem and can cause + crashes on Cortex-M3 if the ARM libgcc is used, for example. The fix + is to include ARCHCPUFLAGS on the gcc command line when asking it to + -print-libgcc-file-name. + * lib/time/lib_gmtimer.c: Correct several calculations that could lead + to errors in dates. + * drivers/pm: Add the beginnings of a NuttX power management sub-system. + * arch/arm/src/stm32/stm32_irq.c: Fix a error introduced in 6.8. + Timeout calculation uses clock_settime() instead of clock_gettime(). + Pretty gross error, but actually it works with the side effect of setting + a bad time. + * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by + Li Zhuoyi (Lzyy). + * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family + submitted by Li Zhuoyi (Lzyy) + * arch/arm/src/stm32_i2c.c: Correct two issues with the STM32 I2C driver: + (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings + need some additional bits; and (2) Correct a hang that will occur on + I2C1 if FSMC is also enabled. + * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h: Add an LM-75 + temperature sensor driver. + * configs/stm3210e-eval/src/up_lm75.c: Add support for the LM-75 on the + STMicro STM3210E-EVAL board. + * sched/clock_gettime.c: Correct an error in the tv_nsec calculation + that happens only config CONFIG_RTC is enabled. + * arch/arm/src/stm32/stm32_i2c.c: Correct some bugs related to waiting + to the I2C STOP condition to be cleared. -apps-6.8 2011-08-19 Gregory Nutt <spudmonkey@racsa.co.cr> +apps-6.9 2011-09-11 Gregory Nutt <spudmonkey@racsa.co.cr> - * apps/examples/nxlines: Added a test for NX line drawing capabilities. + * apps/examples/nxlines: Extend the line drawing text to include drawing + of circles. + * apps/system/i2c: Add an I2C test tool that should help to bring up I2C + devices (when it is fully functional). + * apps/nshlib/nsh_timcmds.c: Add the date command that can be used to + show or set the time (only if CONFIG_RTC is set). pascal-1.0 2011-05-15 Gregory Nutt <spudmonkey@racsa.co.cr> @@ -2642,53 +2699,9 @@ buildroot-1.10 2011-05-06 <spudmonkey@racsa.co.cr>
