Yes, 16MHz crystal with 18pF caps as specified in the crystal datasheet.  I have similar setups on (a) a target PC board, and (b) a breadboard.  I can put the chips in either, same results.  Also have two different FTDI interfaces, same results with either.  I do believe I have the issue well isolated to the chip itself.

fuses are set accordingly, E/H/L = 0xFF/0xDE/0x05.


Did you mean to write "L/H/E"?  Or is that really how you set the fuses?

Ha!  Yes, I meant L/H/E.  Maybe I have dyslexia ;)  Thanx for the catch!

How much time do you want to spend troubleshooting?

Jack Christensen

Hmmm, I've been asking myself that question as well.  Can you give me the Reader's Digest version of what sort of thing you have in mind?
