My Arduino Uno throws a 'verification error; content mismatch' whenever I try uploading any sketch.
Power LED and RX/TX lights work as expected so I guess this can be fixed by re-writing the bootloader on the Arduino. I have a bus pirate but I don't know how the pin connections are made. The ICSP header is used but what are the individual connection to the Arduino ICSP and the Bus Pirate? Should the Arduino be powered using USB or the Bus Pirate's 5v?
Also, what would be the avrdude command line?
