Hello all, When running a program on a PIC16F87A, I sometimes get the following message box: MPLAB ICD Message Box (!) ICD communication failed(4): cmd <701E:1> Please refer to README.ICD for troubleshooting information. [OK] And in the ICD window: Status: ICD Stack Error:cmd<6307:2> I'm working with MPLAB ICD Version 1.44.00, F/W: Ver 2.31.00, ICD connected and running in debug mode. Any tips on this? It sometimes hapens every few minutes, sometimes not in a few hours.
