avrdude: stk500_getsync(): not in sync: resp=0x00

Hello,

I am working with ARDUINO DUE and have a problem with a blink code.
I get the following error : avrdude: stk500_getsync(): not in sync: resp=0x00
I am sure both serial port and board type are correctly chosen.
The led connected to item 13 stays on so as the led indicated that it's on.
But I made the terrible mistake to give 5V at an input. How can I know if the board is dead ?

Thanks,

If you've got your all circuits right. The obvious reason is u've fried up your processor with 5v.

Yes, I'm afraid. Is there a script to test so as to know if my processor still works ?

Check on your USB cables and also try resetting your due , when u do this you should have blinking pin 13 led.

Led 13 stays on but doesn't blink. And the problem is that when I try to write the blink code on the microcontroller, I receive one more time the message "avrdude: stk500_getsync(): not in sync: resp=0x00"..
