	# Dump firmware from nrf51 and maybe other cortex-m devices
	# The script thats missing from http://blog.includesecurity.com/2015/11/NordicSemi-ARM-SoC-Firmware-dumping-technique.html
	# Also inspired by https://tasteless.eu/post/2015/12/32c3ctf-emb400/
	# Requires seperate instace gdb server already running, for my jlink I use
	# openocd -f interface/jlink.cfg -c "adapter_khz 2000; transport select swd;" -f target/nrf51.cfg

	# uicr and ficr are always accessible so you might want to dump those externally and compare?
	# openocd -f interface/jlink.cfg -c "adapter_khz 2000; transport select swd; set WORKAREASIZE 0;" -f target/nrf51.cfg -c "init; reset halt; flash read_bank 1 uicr-normal.bin 0x0 0x100; exit"
