BMP firmware for STM32F303

System vs BMP Bootloader

For simpicity, the ST system bootloader is used. Thi saves additional 4 kB for the BMPfirmware.

Connections

PA2: UART RX
PS3: UART TX
PA0: TDI
PA1: TMS/SWDIO
PA7: TCK/SWCLK
PA6: TDO/TRACESWO
PA5: TRST
PB5: LED green
PB6: LED yellow
PB7: LED red
PB0: VTARGET
PB1: VUSB

Loading/updating BMP firmware

Get into ST bootloader mode with reset or repower and BOOT pulled high. If BMP firmware is already loaded and running, dfu-util can also invoke the bootloader.

dfu-util -d 1d50:6018 -e

List the available devices

dfu-util -l

dfu-util should now list "[0483:df11]" "@Internal Flash /0x08000000/064*0002Kg" . Compile the firmware with

 make PROBE_HOST=f3 clean && make PROBE_HOST=f3

Load firmware

 dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D blackmagic.bin

Multiple BMP devices or STM devices on the USB bus may require additional dfu-util arguments for device selection.
