### Flash the board
You can flash the board using the on-board EDBG programmer via JTAG. Avrdude has
support for programming an AVR via EDBG with its xplainedpro programmer:
support for programming an AVR via EDBG with its xplainedpro programmer.
First, make sure the default fuse settings are correct. In particular, the low
byte fuse are enabling the use of the on-board 16MHz external oscillator.<br/>
WARNING: setting the fuses incorrectly can brick your board!
```
avrdude -p m256rfr2 -c xplainedpro -U efuse:w:0xFF:m
avrdude -p m256rfr2 -c xplainedpro -U hfuse:w:0x1F:m
avrdude -p m256rfr2 -c xplainedpro -U lfuse:w:0xFF:m
```
To flash the board, just call `make` from an application directory with the
`flash` target:
```
make BOARD=atmega256rfr2-xpro -C examples/hello-world flash
