I got a new Mega 2560 board, but I can't upload sketches.
I got errors like avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
I have got a Mega 2560 before,But i didn't get any error like this in the past.
I tried to update the boot loader using Arduino app, I tried to update the firmware for the 8U2 chip using dfu-programmer, but they are no use.
I follow some instructions to use the old 0023 Arduino app on my Mac,but still the error..
Please Help me with this problem. I'd greatly appreciate your help.
