    i was wondering if you might share where you can find the chip. or do you have a part number.

    thanks

    Hi Alastair,

     

    Finally I've got it to work.  Actually the error I saw was okay.  I saw this error after

    I tried to program bootloader from Arduino 022:

    avrdude: verification error, first mismatch at byte 0x3e000
     0x0d != 0xff              
    avrdude: verification error; content mismatch

    But from this URL: http://www.cbxdragbike.com/arduino/bootloaderdocs/index.html

    Actually the above error is normal.  And I programmed the 3 boards to work fine now.

    You'll need Sparkfun AVR Pocket programmer with Arduino.  That's all.  
    You just choose 2560 from board.  Then 'Burn bootloader'..
    In the end, you'll see the error message that I posted above.  
    But in fact, it works fine.  I programmed all 3 boards with the latest firmware.

    Best,

    Peter

    Hi,

     

    I just changed the chip for 3 of my boards.  But I have the same problem with you.  I have Sparkfun AVR Pocket programmer.  But it doesn't work. If you already know how to do this, please let me know.


    Thanks!

     

    Peter
