I followed tutorial to get started with LPCXpresso55S69 Development Board | NXP. Everything was running smoothly until the step where I built my own application based on SDK example. Indeed, after a few Build/Debug loops the board suddently stopped working.

Now, when trying to initiate Debug, the probe is properly being detected:


But SWD link to the cores seams not accessible:


Of course I tried to unplugged the board, restart MCUXpresso, even restart my computer but nothing helped. I also re-flash the on-board probe FW using LPCScript tool, but it didn't helped either.


Is there a way to repair the board ?
