My 52833DK is apparently bricked. "Could not find core in Coresight setup. Abort debug session”

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?
