Small gdb script to enable Black Magic Probe Target Power 'tpwr'.

bmp_tpwr_en.scr

#!/usr/bin/env arm-none-eabi-gdb -nx -batch -x

# The Black Magic Probe has level shifter buffers on its frontend,
# this gdb script enables Black Magic Probe target power,
# this is needed if you are not providing reference voltage from your target.
# Do not run this script or enable target power if you have VREF connected.
# The BMP side TPWR is connected to the 3.3V regulator of the Black Magic Probe
# and it has no protections, so don't fry your target or Black Magic Probe by
# being hasty and not thinking about what you are doing. :D

# do not ask me if I am sure
set confirm off

# This is for Mac OS X
