Re: Refuses to enter ICSP / debug mode on PIC24FJ64GA702
The problem was that MPLAB 5.10 had crashed in some subtle non evident way.
Perhaps it was because I used the IPE in between. I am not sure but for whatever reason, MPLAB was the problem.
Once I restarted the lot, it suddenly started loading firmware into the ICD3 and then everything worked again.
Oh man, what a start to a Friday.
