I have a batch of boards I built that the majority do not appear to want to= program. I've checked the obvious build, but its pretty straight forward = with just the processor, SOT-6 package, couple of resistors. One thing I no= ticed is when using the PICKIT2 to flash, I get the box that pops up about = "Invalid OSCCAL Value detected" What exactly is this telling me, other tha= n the obvious that it found something it didnt expect. I'm seeing this on = brand new parts soldered in and first time attempts at flashing. =20 --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
