We are developing a product based on the Philips 89LPC936 processor and using UV3/C51 with an EPM900 successfully for some time now. Our latest revision to the PCB, however, will not program; each time we get the following error:
"*** Error: Flash CRC Check Failed at sector 7."
All earlier PCB revisions program fine, and the strange thing is these _appear_ to program fine, too, until the last sector (Sector 7) of flash. We assume it is something with the latest PCB rev, but everything _looks_ OK. Does anybody have a suggestion as to where to look, or what else might be wrong?
Thanks,
Mitch
