## Flashing the device
|
||
|
|
|
||
|
|
The STM32F030C8 based Bluepill board does not include a programmer.
|
||
|
|
You have to connect a separate ST-Link programmer to the (SW)DIO, (SW)CLK and GND
|
||
|
|
pins on the board.
|
||
|
|
|
||
|
|
If you want a serial terminal, you have to connect a separate USB-Serial adapter to
|
||
|
|
the PA09 (TX) and PA10 (RX) pins on the board.
|
||
|
|
|
||
|
|
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=bluepill-stm32f030c8 flash
|
||
|
|
```
|
||
|
|
and debug via GDB by simply typing
|
||
|
|
```
|
||
|
|
make BOARD=bluepill-stm32f030c8 debug
|
||
|
|
```
|
||
|
|
|
||
|
|
## Known Issues
|
||
|
|
|
||
|
|
### Flashing fails
|
||
|
|
|
||
|
|
The board does not expose a pin for the reset signal but wires it only to the
|
||
|
|
reset button.
|
||
|
|
You can work around this by pressing the reset button when OpenOCD wants to connect
|
||
|
|
to the Blue Pill, or keep it pressed until OpenOCD tries to connect.
|
||
|
|
Hit the reset button again after flashing in order to boot the newly flashed image.
