This is a port of NuttX to the Atmel AVR32DEV1 board and compatible
|
|
|
|
|
with MCUZone UC3B-CPU board depicted here:

This board is based on the Atmel AT32UC3B0256 MCU and uses a specially
|
|
|
|
|
patched version of the GNU toolchain: The patches provide support for the
|
2023-10-26 02:28:04 +08:00
|
|
|
AVR32 family. That patched GNU toolchain is available only from the
|
2024-02-19 06:22:59 +08:00
|
|
|
Atmel website.
|
|
|
|
|
|
|
|
|
|
STATUS: This port is functional but very basic. There
|
2023-10-26 02:28:04 +08:00
|
|
|
are configurations for NSH and the OS test.

Features
|
|
|
|
|
========
|
|
|
|
|
|
|
|
|
|
- AVR32 AT32UC3B0256 microcontroller
|
|
|
|
|
- mini-USB Connector
|
|
|
|
|
- Power LED (LED1)
|
|
|
|
|
- MCU controllable LEDs: LED2 and LED3
|
|
|
|
|
- S1/RESET and S2 buttons (S2 accessible to user)
|
|
|
|
|

Serial Console
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
The board uses by default the USART1 as serial console.
|
|
|
|
|
The pins PB2 (TXD) and PA24 (RXD) are used for USART1.
|
|
|
|
|
|
|
|
|
|
This way you need to connect a USB/Serial adapter to
|
|
|
|
|
get access to the NuttShell. Connect the TXD from your
|
|
|
|
|
USB/Serial to the RXD of the board, and the RXD from
|
|
|
|
|
USB/Serial to the TXD of the board.
|
|
|
|
|
|
|
|
|
|
There is another detail about the baudrate, you need to
|
|
|
|
|
use 57600 8n1.
