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.
