| NuttX-5.1 |
| --------- |
| |
| This is the 48th release of NuttX. This release adds support for |
| two new MCU architectures in various states of development: |
| |
| * AT91SAM3U (http://www.atmel.com/products/at91/sam3landing.asp?family_id=605) |
| |
| This release adds support for the SAM3U-EK development board with |
| the AT91SAM3U4E MCU |
| (http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562). |
| As with most NuttX architecture releases, the release will be |
| rolled out in two parts: A basic port and an extended port. |
| |
| NuttX-5.1 includes the basic port for the SAM3U-EK board. This |
| release passes the NuttX OS test and is proven to have a valid |
| OS implementation. It supports the basic boot-up, serial console |
| and timer interrupts. A configuration to support the NuttShell |
| is also included. |
| |
| The extended port will also include support for SDIO-based SD |
| cards and USB device (and possible LCD support). These extensions |
| may or may not happen by the NuttX 5.2 release as my plate is |
| kind of full now. |
| |
| * LPC3131 (http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/) |
| |
| This release also adds the complete implementation of the basic |
| port for the NXP LPC3131 MCU on the Embedded Artists EA3131 board |
| (http://www.embeddedartists.com/products/kits/lpc3131_kit.php). |
| That port, unfortunately has stalled due to tools issues. Those |
| tool issues have been resolved and I am confident that the verified |
| basic port will be available in NuttX-5.2. |
| |
| The extended release will follow and should include SDIO-based |
| SD card support and device USB. |
| |
| A few additional features and bugfixes of a minor nature were also |
| incorporated as detailed in the ChangeLog. |
