a quick question please, which hex file(s) have you actually flashed?
the white borad is different
yeah... what I meant was that it's maybe worthwhile to check if on the white board indeed the electrical connections are different or if "only" the printed labelling is incorrect but that the electrical connections are as on the blue boards (I mean, I would doubt that the white-board producers have relayouted this board, whereby having everywhere the identical layout as the blue boards except for the four pads - a missprint of the labels looks likely too me).
OK, send you a PM with a link to a download of a zip file, try the respective hex file(s) for 16mhz...
Please note that I could not test these hex since I don't have the 16MHz hardware... but that's the best I can offer at the moment... if you experience still a problem I could retry.
please report back how it goes
