Firmware Flashing

FLASH_MODE=DFU is set as default

STM32F4 Discovery can mainly be programmed in two different ways:

DFU

  • with the MCU native (embedded in rom) DFU USB bootloader over the micro USB AB connector
  • required hardware: USB to micro and USB to mini usb cable
  • required external software: dfu-util
  • push MCU in DFU mode: connect mini and micro USB to PC, connect pin BOOT0 with 3V (if it doesnt work also BOOT1 (PB2) with GND), press reset button(LED LD7 should light up now), disconnect BOOT0 to 3V
  • more information: DFU page

SWD

  • 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
