Right to the STM32, there is a debugging header with GND, 3V3, SWDIO and SWCLK. Connect GND, SWDIO and SWCLK to your SWD programmer, like the ST-Link found on many STM devboards.<br>
⚠Make sure you properly soldered the headers/wires. Also keep in mind the debugging header pinout can differ on some boards⚠
If you have never flashed your sideboard before, the MCU is probably locked. To unlock the flash, check-out the wiki page [How to Unlock MCU flash](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/How-to-Unlock-MCU-flash).
Do not power the mainboard from the 3.3V of your programmer! This has already killed multiple mainboards.

### Troubleshooting
If you cannot flash the firmware:
- Make sure you properly unlocked the chip
- Make sure you are don't have an already open connection to the chip in another software (st-link utility, ...)
- Make sure you properly soldered the headers/wires, clean contact is mandatory
- Also keep in mind the debugging header pinout can differ on some boards
