I have do a project with a PIC18F458 and debugging it with no problem,
but after i get a PIC18F4620 i get following error
IDCWarm0054: MPLAB IDE has lost communication with the MPLAB ICD 2
I got similar problems so, I have reworked everything from the very begining and now works.
I have followed the instruccions from the internal help info in the MPLAB IDE.
What about you ?
