Firmware Flashing

FLASH_MODE=STLINK is set as default

STM32F3 Discovery can mainly be programmed in two different ways:


  • with onboard STLinkV2 over SWD
  • required hardware: usb to mini USB cable
  • required software: st_flash and st_util from Texane
  • more information: STLink page


  • with the MCU native (embedded in rom) DFU USB bootloader over the mini USB connector
  • required hardware: USB to mini usb cable
  • required external software: dfu-util
  • push MCU in DFU mode: connect user mini (not STLink) USB to PC, connect pin BOOT0 with 3V, press reset button, disconnect BOOT0
  • more information: DFU page
