Hi all,

I run into a very strange thing and I’m stuck. The following has happened 3 or 4 times before and again today and I cannot figure out the reason why: Suddenly the PIC freezes after I transferred to it a newly compiled program. It does not help to reset or cycle power, its frozen solid. There are no errors when compiling (MCS+/MPASM) and non from the programmer and its software (WISP648/xwisp2 ver 1.9.5)! Every time it has happened I have ended up having to re-installing MPLAB, PBP and MCS. After this tedious manoeuvre I re compile the program and the PIC come to life again. This is no different with another PIC, another circuit or a different program and it can strike at any time (at least I haven’t noticed any pattern yet). I have upgraded my XPP to service pack 3 but this made no difference.

So.. my dear friends, have anyone have experienced something similar or have got any clues?

Thanks!
