nuttx-0.4.13
^^^^^^^^^^^^
This is the 45th release of NuttX. 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.
