I've been able to program both of them without problems for weeks. Any example project I try will compile and upload with no issue.
I recently got an Ethernet shield... I'm trying some test sketches and no matter which board I try, with the shield attached I get:
avrdude: stk500_getsync(): not in sync: resp=0x00
As I said, without the Ethernet shield attached all is bliss....
Do I have a bad shield or am I just doing something stupid?
