<![CDATA[StampS3 : A fatal error occurred: No serial data received.]]>The board has been working fine. I have been able to upload sketches from Arduino without problems.

Then I decided to see what the "Start Degugging" button would do for me!

Now I can't upload sketches.

A fatal error occurred: No serial data received.
Failed uploading: uploading error: exit status 2
