Thanks Melanie,

You may have just saved me a few days (or weeks) of frustration. I am reading this thread only 12 hours after sending in my PCB designs for fabrication. After months of design, redesign, double-check, triple-check, I now realize I WILL need a xtal for the bootloader and PC serial comms. (I had really hoped to get away with INTOSC on the PIC18F2525 and use those I/Os for other tasks...oh well).

LUCKILY.......I DID include the pads/traces for a xtal and caps....just in case......

I might try the INTOSC, but only AFTER I get it working with the xtal.

regards,
Jim
