Flashing
DFU Util
Programs are loaded onto the Swan using DFU mode by default. You must install DFU Util before you will be able to flash the STM32F4 Discovery board with your TinyGo code.
- Plug the Swan into your computer’s USB port.
- Put the Swan into DFU mode (press and hold BOOT while toggling RESET).
- Build and flash your TinyGo program using
tinygo flash -target=swan
ST-Link
The Swan includes an SWD header that can be used with an ST Link such as the STLINK-V3MINI. You must install OpenOCD before you will be able to flash the Swan with your TinyGo code.
- Connect the ST-Link debugger to the Swan using the ribbon cable.
- Plug the Swan and the ST-Link into USB ports on your computer.
- Build and flash your TinyGo program using
tinygo flash -target=swan -programmer=openocd
