## Flashing the Device
|
|
|
|
The ATxmega-A3BU Xplained needs an external programmer like atmelice.
|
|
|
|
In order to flash the ATxmega256A3BU, simple run:
|
|
|
|
make BOARD=atxmega-a3bu-xplained flash
|
|
|
|
## Serial Terminal
|
|
|
|
This board needs a serial converter. The default STDIO is at J1 pins 2/3.
|
|
|
|
make BOARD=atxmega-a3bu-xplained term
