## Flashing the device
|
|
|
|
The ST Nucleo-F446RE 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
|
|
|
|
```
|
|
make BOARD=nucleo-f446 flash
|
|
```
|
|
and debug via GDB by simply typing
|
|
```
|
|
make BOARD=nucleo-f446 debug
|
|
```
|
|
|
|
## Supported Toolchains
|
|
|
|
For using the ST Nucleo-F446RE board we strongly recommend the usage of the
|
|
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-
|
|
embedded)
|
|
toolchain.
