Flashing

OpenOCD

Programs are loaded onto the STM32 Nucleo L432KC with the onboard STLink v2 hardware programmer, using the openocd command line utility program to perform the board flashing. You must install OpenOCD before you will be able to flash the STM32 Nucleo L432KC board with your TinyGo code.

  • Plug your STM32 Nucleo L432KC into your computer’s USB port.
  • Build and flash your TinyGo program using tinygo flash -target=nucleo-l432kc
