Flashing
OpenOCD
Programs are loaded onto the STM32F4 Discovery 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 STM32F4 Discovery board with your TinyGo code.
- Plug your STM32F4 Discovery into your computer’s USB port.
- Build and flash your TinyGo program using
tinygo flash -target=stm32f4disco
