I'm stumped. I've never had this error before unless the clock was broken (it isn't). The PIC (PIC16LF88) runs perfectly at 3.5V, will program my "wink" test fragment from the ICD2 as a programmer, and when selected as debugger, all seems OK except for the error. (NO, I don't have ICD2 selected at both programmer and debugger). Neither PGC, MCLR, or PGD is connected to anything except the debugger. Well, MCLR has a 47K pullup on it only to VDD. I haven't tried to run the PIC at 5V because it has some 3.6V max peripherals attached. The PIC runs flawlessly for the wink test. Any ideas, fellow PIClisters? --Bob -- Note: Attachments must be sent to attach@engineer.cotse.net, and MAY delay replies to this message. 520-219-2363 -- Note: Attachments must be sent to attach@engineer.cotse.net, and MAY delay replies to this message. 520-219-2363 _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
