Firmware BMP for STM32F407 DISCO boards

Kept for historical reasons to load BMP bootloader to the STM32F103 of the onboard STLINK or external STLINKs. As stlink-tool now allows to load BMP firmware via the original STLINK bootloader is no longer really needed.

Connections:

PC2: TDI
PC4: TMS/SWDIO
PC5: TCK/SWCLK
PC6: TDO/TRACESWO

PC1: TRST
PC8: SRST

Alternate build for stm32f401 stm32f411 MiniF4 aka BlackPillV2 boards.

Connections:

• JTAG/SWD

  • PA1: TDI
  • PA13: TMS/SWDIO
  • PA14: TCK/SWCLK
  • PB3: TDO/TRACESWO
  • PB5: TRST
  • PB4: SRST

• USB USART

  • PB6: USART1 TX (usbuart_xxx)
  • PB7: USART1 RX (usbuart_xxx)

• +3V3.

  • PB8 - turn on IRLML5103 transistor

How to Build

cd blackmagic
make clean
make PROBE_HOST=f4discovery BLACKPILL=1

How to Flash with dfu

• After build:
• 1. apt install dfu-util
• 2. Force the F4 into system bootloader mode by jumpering "BOOT0" to "3V3" and "PB2/BOOT1" to "GND" and reset (RESET button). System bootloader should appear.
• 3. dfu-util -a 0 --dfuse-address 0x08000000 -D blackmagic.bin

To exit from dfu mode press a "key" and "reset", release reset. BMP firmware should appear
