Blinking LED sketch to work on Arduino DUE

changks:
It seems I got a problem in my Arduino DUE.

You haven't stated the problem.

changks:
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.

changks:
Verify successful
Set boot flash true
CPU reset.

This is not an error.

changks:
HELP ME! What should I do? Can you ship another one to me?
