while I was developing my software on the OM27462CDK devboard the following error occurred:


LPCXpresso RedlinkMulti Driver v8.2 (Sep  5 2016 10:12:38 - crt_emu_cm_redlink build 725)

Error message from debugger back end:

Remote communication error.  Target disconnected.: No error.

Remote communication error.  Target disconnected.: No error.



 I did not touch the Board. I just changed some lines of code and clicked on debug.

After a while the debugging did not start anymore an above described message appears.

It looks to me like the MCU is broken?


Has somebody an Idea what's the reason and how to fix it?
