### Flashing the Firmware with OpenOCD
Another option to deploy the firmware on ST Discovery or Nucleo boards with a
ST-LINK interface uses [OpenOCD]( Connect the board with
a mini USB cable to its ST-LINK USB port and then use the make target
`deploy-openocd`. For example, if you have the STM32F4DISCOVERY board:
$ make BOARD=STM32F4DISC deploy-openocd
The `openocd` program, which writes the firmware to the target board's flash,
is configured via the file `stmhal/boards/openocd_stm32f4.cfg`. This
configuration should work for all boards based on a STM32F4xx MCU with a
ST-LINKv2 interface. You can override the path to this configuration by setting
`OPENOCD_CONFIG` in your Makefile or on the command line.
Accessing the board
# This script configures OpenOCD for use with an ST-Link V2 programmer/debugger
# and an STM32F4 target microcontroller.
# To flash your firmware:
# $ openocd -f openocd_stm32f4.cfg \
# -c "stm_flash build-BOARD/firmware0.bin build-BOARD/firmware1.bin"
# For a gdb server on port 3333:
# $ openocd -f openocd_stm32f4.cfg
