Flashing the device

The ST Nucleo-F334R8 board includes an on-board ST-LINK V2 programmer. The easiest way to program the board is to use OpenOCD. Once you have installed OpenOCD (look here for installation instructions), you can flash the board simply by typing

1
make flash
and debug via GDB by simply typing
1
make debug
