Daughterboard
comming soon :) git repo
Components:
Diode: Standard types (like 1N4007) will work
Resistors: 2k2 and 22k, 0,1%
Caps: Low ESR type, 10-50µF
Firmware Flashing
FLASH_MODE=STLINK is set as default
STM32F4 Discovery can mainly be programmed in two different ways:
STLINK
- 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
DFU-UTIL
- 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(for power) and micro USB to PC, connect pin BOOT0 with 3V (if it doesn't work, also BOOT1 (PB2) with GND), press reset button(LED LD7 should light up now), disconnect BOOT0 (and BOOT1)
- more information: DFU page
