DFU
Arduino IDE:
Select Tools -> Upload Method -> DFU
To put the board in DFU mode, hold down the boot button while pressing and releasing the reset button.
ST-Link
Arduino IDE:
Select Tools -> Upload Method -> STLink
Requires an ST-Link debugger connected to SWCLK, SWDIO, Vref, and GND, refer to pin mapping diagram.
