Hi guys, I have the same problem. I mean I bought my due board from Arduino Store one month ago and everything worked fine. After that I left it on my desk inside its box for some weeks because I was busy with my work. Yesterday I went back to play and nothing worked.
Compile is OK...
Upload using Programming Port is Ok..
but after that nothing happens as described previously by dinofizz, no led blink, no serial operation..
Do you have any ideas? Does anybody know if there is a self test procedure? Should I contact Arduino store?
