Flashing

OpenOCD

Programs are loaded onto the LoRa-E5 with an 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 LoRa-E5 board with your TinyGo code.

  • Connect an ST-Link device to the SWD/SWIM headers.
  • Plug your LoRa-E5 board into your computer’s USB port.
  • Plug your ST-Link device into your computer’s USB port.
  • Build and flash your TinyGo program using tinygo flash -target=lorae5
