-nuttx-0.4.13 2009-11-04 Gregory Nutt <spudmonkey@racsa.co.cr> - - * include/nuttx/mtd.h. Added a simple interface definition to support some - FLASH, EEPROM, NVRAM, etc. devices. - * driver/mtd/m25px.c. Added a driver for SPI based FLASH parts M25P64 and M25P128. - * configs/stm3210e-eval/usbserial. Add a USB serial configuration for the STM32. - Depends on the STM32 USB driver. - * arch/arm/src/cortexm3/up_switchcontext.S & up_svccall.c. Made an improvement - to context switching. There are two types of context switches: interrupt - context switches and background/user context switches. This change should - improve the performance of those background/user context switches by a factor - of about two. - * arch/arm/src/stm32/ - fix several typos in the serial logic. It turns out - that these typose don't make any difference as long as you use only one - serial port and all uarts are configured the same. But the typos are bugs - waiting to happen in any other configuration. - * arch/arm/src/stm32/ - You have to configure CTS/RTS function pins for USART - 2 and USART 3 even if you are not using flow control. - * arch/arm/src/stm32/stm32_usbdev.c - Added a USB device-side driver for the - STM32. NOTE: This is an early release of the USB driver. There is at least - one known issue. The examples/usbserial test only executes correctly under - certain conditions (see the full bug description in the TODO list). - * arch/arm/src/stm32/stm32_rcc.c - Fixed an error in clock initialization. - On some boards (none of mine), the HSE (high speed external clock) delay - loop times out if the optimization level is high. The STM32 then falls - back to the HSI (internal clock), and the system clock is too slow by a - factor of 11.1%. This was fixed by simply add the volatile storage class - to the timeout loop counter - * arch/arm/src/stm32/stm32_irq.c - Fixed a critical bug in the interrupt - control logic. The wrong register was being used for interrupts in a - certain range. Worked fine until you try to use an interrupt in that - range! - -pascal-0.1.2 2008-02-10 Gregory Nutt <spudmonkey@racsa.co.cr> - - * Add logic to build and link with the ZDS-II toolchain - use with the z16f. - * Make sure that POFF header structures are aligned - * Standardized POFF file format to big-endian - * Break up large switch statements to lower complexity - and eliminate a compiler bug - * Changes so that runtime compiles with SDCC. - -buildroot-0.1.7 2009-06-26 <spudmonkey@racsa.co.cr> - - * configs/avr-defconfig-4.3.3: Added support for AVR to support a NuttX - port of the ATmega128. - * toolchain/nxflat: Added logic to build NuttX NXFLAT binding support tools - * toolchain/genromfs: Added support for the genromfs tool -- -
