+STATUS: This port is functional but very basic. There
 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)
+  - 12MHz (main clock) and 32KHz for RTC
+
+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.
