Some tuning is still needed. - * configs/mirtoo/nxffs: Add an alternative NSH configure for the Mirtoo - module for testing the on-module SST 25 chip using the NXFFS file system. - * arch/arm/src/lpc43xx and arch/arm/include/lpc43xx: The NXP LPC43xx port - is slowly evolving in these directories. - * configs/stm3210e-eval/pm: Add a new configuration for testing STM32 power - management. - * configs/stm3210e-eval/scripts: Moved all of the duplicate ST3210-EVAL - linker scripts into one set of linker scripts at this location. - * configs/stm3210e-eval/src/up_buttons.c, up_lcd.c, and up_pm.c: New logic - for testing STM32 power management. - * configs/lincoln60: Add a configuration to support the Micromint Lincoln60 - board. - * configs/ekk-lm3s3b96: Add a configuration to support the TI/Stellaris - EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V. - * arch/arm/src/lpc43xx/chip: Created header files for *all* (really) - lpc43xx registers and all bit-fields. - * configs/lpc4330-xplorer: Added a configuration for the NXP LPC43XX - Xplorer board. This is just to facilitate testing of the LPC43xx - port but will, with any luck, become proper board support for that - board. - * arch/arm/src/lm3s/lm3s_syscontrol.c: Fix an optimization related problem - by adding a volatile qualifier to a timing loop. Oddly, the consequence - of the bug is that when debug was off, the LM3S platform too a long time - to boot. It now boots rapidly whether debug is on or off. - * arch/*/include/limits.h: Change all values in all limits.h for all - architectures to signed decimal; the hex values were not sign extending - appropriate in most uses (reported by Lorenz Meier). - * arch/arm/src/stm32/chip/stm32f103/7vc_pinmap: Fix typographical error in - two pinmap definition files. - * lib/net/lib_inetntoa.c: Fix typographical error that cause compilation - failure on platforms that do not support passing of structures as - parameters. - * arch/arm/*/lpc43xx and configs/lpc4330-xplorer and code complete and - ready for testing.

So for the architectures - that cannot use their GCC toolchain's stdarg.h file, they can use this - alternative by defining CONFIG_ARCH_STDARG_H=y.

Allow for + a perverse configuration that has socket descriptors and streams but no file + descriptors (sure, why not?). + * sched/: Stylistic clean-up of all files. Some of these files are pretty old + and do not follow current NuttX coding standards in detail. + * fs/: More stylistic file clean-up. + * mm/: More stylistic file clean-up. + * drivers/ and drivers/serial/: More stylistic file clean-up. + * arch/arm/src/lpc43xx/lpc43_clockconfig.c: Fix PLL1 bit manipulation logic. + Critical bugfix! This would often cause the LPC43xx to fail to boot. + * arch/arm/src/lpc43xx/lpc43_rgu.c: The soft reset logic called from the + beginning of __start seems cause problems. A magic delay seems to improve + the logic some. But I suspect that real fix is to get rid of all of the + soft reset logic. This would also be a critical bugfix if I believed + that it really fixed all of the issues. + * arch/arm/src/lpc43xx/chip/lpc43_cgu.h: Fix a bit mask in the PLL1 + control register. Critical bugfix. + * arch/arm/src/lpc43xx/lpc43_clockconfig.c and configs/lpc4330-xplorer/include/board.h: + Implement PLL1 ramp-up logic; Now the LPC43xx is running at 204MHz. + * configs/lpc4330-xplorer/*/defconfig: Re-calibrated delay loops using + the 204MHz clock. The LPC43xx ripping rips! This calibration was performed + with symbols enabled and all optimization disabled. It will need to be + better recalibrated again down the road. + * arch/arm/src/stm32/stm32_exti.c: Renamed to rch/arm/src/stm32/stm32_exti_gpio.c + to make a little room in the file name space. + * arch/arm/src/stm32/stm32_exti_alarm.c: Add initial logic to attached the + RTC alarm EXTI interrupt.

It now creates an MTD driver to access SPIFI... + but the driver still does not work. + * arch/arm/src/stm32 and arch/arm/include/stm32: Make name of RTC ALARM interrupt + common on STM32 F1,2,4 + * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the + STM32F100x "Value Line" devices. This includes changes to stm32F10xx_rcc.c that + add the ability to run the chip off the internal oscillator. There is no open + board configuration for this part yet (the STM32VLDiscovery would be a candidate). + Contributed by Mike Smith. + * arch/arm/src/stm32: Fixed typos in conditional compilation in the CAN and DMA + and some pin configuration. This would have caused problems for STM32 F107xx. + Typos noted by Mike Smith. + * arch/arm/src/lpc43xx/lpc43_serial.c: Add support for certain RS-485 features + * lib/termios/lib_cfsetispeed.c, lib_cfsetospeed.c, lib_tcflush.c: Add + simple implementations of cfsetispeed(), cfsetospeed(), and tcflush(). + * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: + Add APIs to support setting non-standard BAUD values not supported by POSIX + termios. These are non-standard interfaces but have a precedence: There are + similar interfaces in AIX. + * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: + Sigh... removed. We don't need any more almost standard interfaces! (SVN + revision 4968 if you want the short-lived code). + * include/termios.h and lib/termios/*: Open the existing, standard termios + interfaces to permit some non-standard baud settings. The new termios definitions + still supports the POSIX standard except that it does not strictly enforce + baud rate settings, permitting some non-portable, but useful baud rate settings + (this is what the short-lived AIX-like interfaces would have accomplished as well). + * include/termios.h and lib/termios/*: Redesigned yet again (this is getting + painful. NuttX now supports the BOTHER baud setting just as Linux does. termios + Bxxx definitions are again encoded; cf[set|get][o|i]speed now deal with only the + encoded values. If the encoded baud is set to BOTHER, then the values in the (non- + standard) c_ispeed and c_ospeed baud values may be accessed directly. + * arch/arm/src/stm32/stm32_serial.c: Add minimal termios support for the STM32 + (BOTHER style baud settings only).

Correct a case where interrupts were not + being re-enabled. Found by Diego Sanchez. + * configs/mirtoo/nxffs/defconfig: This Mirtoo NXFFS configuration now uses the + open Pinguino toolchain by default. This is necessary because the free C32 + toolchain does not support any optimization and the unoptimized NXFFS image + hits the PIC32MX2 FLASH size (128K). There is plenty of room to grow using + the Pinguino toolchain with -O2 optimization. + * configs/mirtoo/src/up_adc.c.

As a result, %s, %12s, and %-12s all + produced the same output. + * lib/stdio/lib_libdtoa.c: Fix several issues with presenting floating + point numbers (conversions are fine, but presentation was bad). This + is a critical bug fix if you use printf or sprintf to deal with floating + point numbers. + * lib/stdio/lib_libdtoa.c and lib_libvsprintf.c: Correct some floating + point options. + * arch/arm/lpc43xx/lpc32_usb0dev.c: Add framework for development of + an USB0, device-side driver for the LPC43XX. The initial check-in, + however, is simply for the LPC31xx driver with name changes. The + LPC31xx has the same USB IP, but will require some additional initialization + (and lots of testing) before it can be used with the LPC43xx. + * nuttx/Documentation/NuttShell.html: Added a section covering ways to + customize the behavior of NSH. + * arch/arm/src/stm32/chip/stm32f1*_pinmap.h: STM32 CAN TX/RX pins reversed; + inconsistent conditional compilation.
