AV32DEV1. This port uses the www.mcuzone.com AVRDEV1 board based on the
|
|
|
|
|
Microchip AT32UC3B0256 MCU. This port requires a special GNU avr32 toolchain
|
|
|
|
|
available from atmel.com website. This is a windows native toolchain and
|
|
|
|
|
so can be used only under Cygwin on Windows.
|
|
|
|
|
|
|
|
|
|
**STATUS:** This port is has completed all basic development, but there
|
|
|
|
|
is more that needs to be done. All code is complete for the basic NuttX
|
|
|
|
|
port including header files for all AT32UC3\* peripherals. The untested
|
|
|
|
|
AVR32 code was present in the 5.12 release of NuttX. Since then, the
|
|
|
|
|
basic RTOS port has solidified:
|
|
|
|
|
|
|
|
|
|
- The port successfully passes the NuttX OS test
|
|
|
|
|
(apps/examples/ostest).
|
|
|
|
|
- A NuttShell (NSH) configuration is in place (see :ref:`NSH <nsh>`).
|
|
|
|
|
Testing of that configuration has been postponed (because it got
|
|
|
|
|
bumped by the Olimex LPC1766-STK port). Current Status: I think I
|
|
|
|
|
have a hardware problem with my serial port setup. There is a good
|
|
|
|
|
chance that the NSH port is complete and functional, but I am not yet
|
|
|
|
|
able to demonstrate that. At present, I get nothing coming in the
|
|
|
|
|
serial RXD line (probably because the pins are configured wrong or I
|
|
|
|
|
have the MAX232 connected wrong).
|
|
|
|
|
|
|
|
|
|
The basic, port was be released in NuttX-5.13. A complete port will
|
|
|
|
|
include drivers for additional AVR32 UC3 devices -- like SPI and USB ---
|
|
|
|
|
and will be available in a later release, time permitting. Refer to the
|
|
|

NuttX board
