I have to burn the bootloader on my Arduino Mega2560. I’m using another Mega2560 as ISP, on which I uploaded the sketch “ArduinoISP”. Then I made the following connections between the two boards’ pins:
Mega2560 with the sketch Mega2560 to be programmed
and the RESET of the board with the sketch is connected to ground with a 100nF capacitor.
After that I selected “Arduino as ISP” and then “burn the bootloader”; TX and RX started to blink and after a couple of minutes the IDE of Arduino gave me the following error:
avrdude: verification error, first mismatch at byte 0x1e000 0xff != 0x0d avrdude: verification error; content mismatch
and the board to be programmed started to blink.
What am I doing wrong? I have not any external AVR-writer and the only boards I own are Arduino Mega2560 and Arduino Fio.
Thanks for any help
