Hi there,

   Thanks for the help. It appears that the problem is actually with
avrdude. I haven't isolated the problem well enought to make a bug report,
but I did manage to fix our issue. After processing the bin file if I
convert it back to hex before burning it everything works well. It's quite
strange, but worked for me, so :)

   Replying so the next guy can find an answer in the archives *smile*.
