I have custom hardware that is working fine. No issues. I can program, erase, debug with no issues. I have been working on making some changes in the bootloader, and I've run into some issues with two chips completely locking up and I can't recover them.
Seems to occur after exiting debug in Keil, specifically debugging the bootloader.
The chip locks up, and I can not recover using nRFgo Studio or nrfjprog.
nrfjprog --recover --log
nrfjprog verion 9.6.0

The two boards in question are now sitting in a state where they are dumping power and warming up. I can't stop them, as they are sealed units with internal batteries. I have no idea what state the chip is in, because I can no longer connect to it.
Any thoughts on what I might have done, or how I could recover them? (Other than a power cycle, which would require I break them open).
