## Flashing the device
|
|
|
|
### Flashing the Board Using OpenOCD
|
|
|
|
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](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD) for
|
|
installation instructions), you can flash the board simply by typing
|
|
|
|
```
|
|
BOARD=nucleo-f334r8 make flash
|
|
```
|
|
and debug via GDB by simply typing
|
|
```
|
|
BOARD=nucleo-f334r8 make 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-f334r8 PROGRAMMER=cpy2remed flash
|
|
```
|
|
@note This PROGRAMMER requires ST-LINK firmware 2.37.26 or newer. Firmware updates
|
|
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
|
|
|
|
## Accessing RIOT shell
|
|
|
|
Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface,
|
|
provided by integrated ST-LINK programmer. ST-LINK is connected to the
|
|
microcontroller USART2.
|
|
|
|
The default baud rate is 115200.
|
|
|
|
## Supported Toolchains
|
|
For using the ST Nucleo-F334R8 board we strongly recommend the usage of the
|
|
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
|
|
toolchain.
