## Flashing the Device
|
|
|
|
The ATxmega-A1 Xplained needs an external programmer like atmelice.
|
|
|
|
In order to flash the ATxmega128A1, simple run:
|
|
|
|
make BOARD=atxmega-a1-xplained flash
|
|
|
|
## Serial Terminal
|
|
|
|
The CDC-ACM will enumerate a /dev/ttyACM device. The STDIO at CDC-ACM shares
|
|
with J4 pins 2/3.
|
|
|
|
make BOARD=atxmega-a1-xplained term
|
