last time I had an issue, it was a LVP or such configuration bit. The '505 is so bare bones...internal osc, mclr, wdt....nothing I can see that would prevent it from going into debug. Anyone have a suggestion? I'm traveling this week, so hopefully might see an answer today before I hit the road. It does connect, says it programs, just wont enter the debug mode -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
