## Flashing the device
|
|
|
|
### Flashing the Board Using OpenOCD
|
|
|
|
The ST Nucleo-F091RC 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-f091rc flash
|
|
```
|
|
and debug via GDB by simply typing
|
|
```
|
|
make BOARD=nucleo-f091rc debug
|
|
```
|
|
|
|
### Flashing the Board Using ST-LINK Removable Media
|
|
|
|
On-board ST-LINK programmer provides via composite USB device removable media.
|
|
Copying the HEX file causes reprogramming of the board. This task
|
|
could be performed manually; however, the cpy2remed (copy to removable
|
|
media) PROGRAMMER script does this automatically. To program board in
|
|
this manner, use the command:
|
|
```
|
|
make BOARD=nucleo-f091rc PROGRAMMER=cpy2remed flash
|
|
```
|
|
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
|
|
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
|
|
|
|
## Supported Toolchains
|
|
For using the ST Nucleo-F091RC board we strongly recommend the usage of the
|
|
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
|
|
toolchain.
