Flashing
OpenOCD
Programs are loaded onto the STM32 Nucleo WL55JC with the onboard STLink 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 WL55JC board with your TinyGo code.
- Plug your STM32 Nucleo WL55JC into your computer’s USB port.
- Build and flash your TinyGo program using
tinygo flash -target=nucleo-wl55jc
