I'd suggest you to check if the people in charge of assembly has at least the precaution of touching the metal frame while opening the antistatic bag of the board and also while installing it, as you said that they have no ESD protection on their workbench, and specially that your board to be the last one assembled, after a first test of the system without it. Or with a known bad one ;-) And if it onl happens at first boot, I realy believe it is ESD. Francisco -- http://www.piclist.com hint: The PICList is archived three different ways.
