Hello everybody,
Since a few time I have an issue With My Mega 2560
It is now impossible to upload sketches with the USB port
I had to buy an USBTINYISP which can upload sketches
Blink sketch is working fine on it
But... when I try to print data on the serial monitor Nothing appear.
I tried the loop back test : the leds tx and rx are blinking when I send text to arduino but Nothing is printed on the serial monitor.
Driver seems ok
I tried to burn the bootloader here is what I get :

I hope that you can help me with this and that my board is not dead...
The serial port still not working
Thank you for reading
