My 52833DK is apparently bricked. I get the message "Could not find core in Coresight setup. Abort debug session” When I try to load code (IAR) into the board. It was working fine before but I was playing with the PWMs and maybe I sent it into outer space and it cannot recover after a reset? I tried reloading the bootloader which worked but did not fix the problem. J-Link will not connect. In fact the GUI just crashes when I select the 833. I have another DK that still works fine but this board has a lot of custom wiring that I do not want to throw away. What to do?
Seems the DK may be damaged?
Have you tried connect the debug out from the working kit to debug in on the failing kit? This could narrow down what is failing.
I assume you have tried 'nrfjprog --recover'
