This release adds support for two new MCU architectures in various states of development:

This release completes the verification of the basic port for the NXP

This basic port includes basic boot-up, serial console, and timer interrupts. This port

has been verified on the using the NuttX OS test and includes a working

implementation of the NuttShell (NSH).

As with most NuttX architecutre releases, the release will be rolled out in
|

two parts: A basic port and an extended port.

<p>
|
||||
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.
|
||||
</p>
|
||||
<p>
|
||||
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.

* arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework
|
||||
to support the NXP LPC3131 MCU
|
||||
* Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131
|
||||
(LPC3131) is code complete and waiting for me to get hardware in
|
||||
hand.
|
||||
* arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek -
|
||||
Added the basic framework needed to begin a port for the SAM3U-EK
|
||||
development board.
|
||||
* confgs/ea3131/tools: Added a tool to create a image suitable for
|
||||
use with the LPC313x bootloader.
|
||||
* configs/sam3u-3k/ostest - Completed verification of the basic NuttX
|
||||
OS test for the SAM3U.
|
||||
* arch/arm/src/common/up_createstack - stack was always been cleared
|
||||
when it was allocated. This is a good feature for monitoring the
|
||||
stack during debug, but really hurts thread start-up performance.
|
||||
Clearing is now done if CONFIG_DEBUG=y only. Changes was only made
|
||||
for arm, but really should be made for all architectures.
|
||||
* configs/sam3u/nsh - Added NSH configuration for SAM3U
|
||||
* arch/arm/src/sam3u/sam3u_pio.c - Fix an address calculation error
|
||||
that caused ports B & C to get mapped to the PIOA base address.
|
||||
This is an important bugfix! (a patch is available)
|
||||
* arch/arm/src/lpc313x/lpc313x_boot.c - Fix an error in the vector
|
||||
initialization was causing a memory fault.
|
||||
* lib/lib_strtod.c - Add strtod()
|
||||
* lpc3131/ea3131 - Several bring fixes submitted by David Hewson. The
|
||||
lpc3131 is almost there! Thanks David!
|
||||
* arch/arm/src/arm/up_head.S - Corrected backward conditional compilation
|
||||
that selects if vectors are located at 0x0000:0000 or 0xffff:f000.
|
||||
This fixes the last show stopper bug in the lpc313x bring-up.
|
||||
* configs/ea3131/nsh - Added a NuttShell (NSH) configuration for the
|
||||
EA3131.
