Hi all, I've recently started using the arduinos by ordering a UNO and a MEGA.
So far the experience has been very good, much better to prototype than using PICs + programmer
However, I've run into a problem on my MEGA board. I am not able to upload any programs to it and the indicator led (L) blinks at a rate of ~10Hz unless I keep the reset button depressed. I've tried the loopback test so I know the pc / arduino communications are (still) working.
My initial hunch was that the bootloader was somehow broken, so I tried to upload a new one using ArduinoISP.
However, avrdude reported:
avrdude: Device signature = 0x000000
So I copied the commandline and added -F, now the process continued, but there where errors. I tried several times, but they usualy gave errors regarding the fuse-state. And even when it did manage to finish, the MEGA would instantly go back to the ~10Hz blinking and not being able to accept new programming.
Have I somehow fried my MEGA? What other steps can I take to try and restore it?
thanks in advance!
