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 for installation instructions), you can flash the board simply by typing
and debug via GDB by simply typing
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.
