| NuttX-0.4.13 |
| ------------ |
| |
| This is the 45th release of NuttX. The release extends the support |
| for the STMicro STM32 microcontroller. Minimal 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. |
