Been busy developing a little project on a Arduino Duemilanove with a 168, all working fine. However if I plug the ethernet board into an Arduino pro (from spark fun) everything works except the ethernet :-/
Now, the Arduino pro has a 328 on board, so I tried my Duemilanove with a DIP 328, and that worked perfectly. Still no go on the pro board though.
I haven't got another SPI device I can easily test with.
Any ideas chaps?
