This plugin provides a single Focus command: firmware.dump, which dumps the firmware’s executable code. One might rightfully wonder what purpose this serves when the source code is available, but rest assured, there is one: in case one wants to temporarily replace their firmware, then put it back on, without having to carry the HEX file around, this command makes that possible: dump the contents, turn them into HEX, and it can be re-flashed at any point. We get a HEX file on-demand, and don’t have to carry it around!

The intended primary user of this feature is Chrysalis.
