I have checked schematics and actual wiring of board more than twice now, but I can't get any response from my propeller. I'm using a propplug to program, which verifies for ram but throws an error when verifing for eeprom. I know all of the connections are right but I can't even get a simple pin test program to toggle some pins. I have used a 5.00MHz crystal on all PLL settings and have also used RCFAST and RCSLOW. I have two chips and neither work. All power supplies are good with VDD at 3.27V. another problem is that none of the crystals that I have produce any output whatsoever. Whats the deal, did I just get a bad set of chips?

It might be helpful for you to post your schematic and your simple test program.
