It seems I got a problem in my Arduino DUE.
You haven't stated the problem.
I got the following message on Serial Monitor:
To avoid confusion: That is not the serial monitor. That is the output console. The serial monitor is different and must be opened separately.
Set boot flash true
This is not an error.
HELP ME! What should I do? Can you ship another one to me?
