| NuttX-4.14 |
| ---------- |
| |
| This is the 46th 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 and extended in NuttX-0.4.13 to include |
| initial USB support. This completes the STM32F103ZET6 and adds: |
| |
| New Generic RTOS Features: |
| |
| * Added generic support that can be included in any block driver |
| to provide read-ahead buffering and write buffering for improved |
| driver performance. |
| * Added a generic worker thread that can used to defer processing |
| from an interrupt to a task. |
| * Defined a generic SD/SDIO interface can can be bound to a MMC/SD |
| or SDIO driver to provide SDIO support. |
| * Implemented a an SDIO-based MMC/SD driver using this new SDIO |
| interface. |
| |
| New STM32 Features: |
| |
| * Add support to configure an STM32 input GPIO to generate an |
| EXTI interrupt. |
| * Added support for buttons on the STM3210E-EVAL board. |
| * Implemented an STM32 version of the common the SDIO interface. |
| * Added a configuration to exercise the STM32 with the USB mass |
| storage device class example. |
| |
| This release also corrects some important bugs in the early STM32 release: |
| |
| * Correct error handling in the mount() logic. |
| * Fixed several STM32 DMA-related issues. Integrated and debugged |
| STM32 DMA functionality that was added in 0.4.12. |
| * Fixed several bugs in the STM32 USB device-side driver. |
| |
| NOTE: This version, 4.14, is equivalent to what would have been |
| called 0.4.14 to follow 0.4.13. The zero has been eliminated from |
| the front of the version number to avoid confusion about the state |
| of development: Some have interpreted the leading zero to mean |
| that the code is in some way unstable. That was not the intent. |
| Beginning in January 2010, I will switch to the 2010.nn versioning |
| as many others have done to avoid such confusion. |
