We have a project going on that is using an 18F8525, where we have one chip out of 5 that behaves itself, meaning that it will program, debug, all those things. Boards are all the same, stripped of everything but the oscillator, chip and programming header. Simple as it can be. Someone else wondered....is it possible for a chip to get into a state where it does not want to program. I believe the error seeing is on verification, if under program mode, it is read, then programmed it will come back with no errors. However, it will show errors if just programmed. THoughts? _________________________________________________________________ Check out Election 2004 for up-to-date election news, plus voter tools and more! http://special.msn.com/msn/election2004.armx -- http://www.piclist.com#nomail Going offline?
