Installation instructions

STM32 via ST-Link

Nucleo and Discovery boards typically include a built-in ST-Link programmer.

A .bin or .hex file can be flashed using st-flash.

# Optional erase to clear existing filesystem.
st-flash erase

# Flash .bin
st-flash write firmware.bin 0x08000000
# or, flash .hex
st-flash --format ihex write firmware.hex

A .hex file can be flashed using STM32 Cube Programmer.

STM32_Programmer.sh -c port=SWD -d firmware.hex -hardRst

STM32 via DFU

Boards with USB support can also be programmed via the ST DFU bootloader, using e.g. dfu-util or pydfu.py.

To enter the bootloader the BOOT0 pin can be connected to VCC during reset, or you can use machine.bootloader() from the MicroPython REPL.

dfu-util --alt 0 -D firmware.dfu
