# This script configures OpenOCD for use with an ST-Link V2 programmer/debugger
# and an STM32L4 target microcontroller.
#
# To flash your firmware:
#
#    $ openocd -f openocd_stm32l4.cfg \
#        -c "stm_flash build-BOARD/firmware0.bin 0x08000000 build-BOARD/firmware1.bin 0x08004000"
#
# For a gdb server on port 3333:
#
#    $ openocd -f openocd_stm32l4.cfg
