Teasing out those details is a struggle and if you change chips you have to start all over even if both chips are, say, Cortex-M3 based! Another way is to use the debug output functionality of OpenOCD and force the check against an invalid serial number. Using OpenOCD as just a programmer instead of a debug tool is very convenient in cases of mass production where you already have a prebuilt and already debugged image and you only need to download that image to the target device. In general, many ARM chips can be debugged using the SWD (single-wire-debug) protocol. My aim is to make this tutorial usable for both beginners and advanced users so I’ll start with the basics.
