The release extends the support for the STMicro +STM32 microcontroller. Minimul support for the STM3210E-EVAL development board based +around the STM32F103ZET6 MCU was released in NuttX-0.4.12. This release adds: + + * A simple interface definition to support some FLASH, EEPROM, NVRAM, etc. devices. + * Verified SPI operation using driver for SPI based FLASH parts M25P64 and M25P128. + * Improved Cortex-M3 context switching. This should improve context switching + performance be 2x in certain cases. + * Added a USB device-side driver for the STM32. This is an early release of a + very complex driver; some bugs are expected. + * The USB driver has been verified against the USB serial device class driver. + There is at least one known outstanding issue (see the full bug description in + the TODO list). + +This release also corrects some important bugs in the early STM32 release: + + * Fixed several errors the prevented operation of NuttX on an STM32 development + board using USART2 as the serial console. + * Fixed and optimization-dependent race condition in the clock initialization. + * Fixed a critical bug in the interrupt control logic that could cause interrupt + operations to failed used for interrupts in a certain range. + +This tarball contains a complete CVS snapshot from November 4, 2009 |
