ATXmega*A4U Breakout Documentation

Documentation for the ATXmega*A4U breakout boards:

Revision 1:

Revision 2:

Atmel Studio 6 supports these chips fully, and includes their Framework for building applications.

You will need a programmer capable of PDI, which includes the AVR-ISP MkII and the JTAG-ICE MkII.  I plan on preprogramming future boards with Atmel’s DFU firmware loader, which will allow you to load firmware via Atmel’s FLIP software without a dedicated programmer.

Development with the Linux avr-gcc stack is complicated by the significant lag between Atmel releasing chips and these projects supporting them.  I will put together a page with my patches and build instructions shortly.
