## Flashing the device
The ST Nucleo-F303K8 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](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD)
for installation instructions), you can flash the board simply by typing.

```
BOARD=nucleo-f303k8 make flash
```
and debug via GDB by simply typing
```
BOARD=nucleo-f303k8 make debug
```


## Supported Toolchains
For using the ST Nucleo-F303K8 board we strongly recommend the usage of the
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
toolchain.
