Flashing

OpenOCD

Programs are loaded onto the Nucleo F103RB with the onboard STLink v2-1 programmer connected via USB to the host, using the openocd command line utility program to perform the board flashing. You must install OpenOCD before you will be able to flash the Nucleo F103RB board with your TinyGo code.

  • Plug the onboard STLink v2-1 programmer into your computer’s USB port.
  • Build and flash your TinyGo program using tinygo flash -target=nucleo-f103rb - if you encounter OpenOCD connectivity errors try holding the black reset button down while flashing.
