It is always always the user :-)
Don't blame uisp, but I haven't tried the new release.
But I remeber it was always my fault if a spi-flasher failed.
Do you have checked your fuses? Afaik you cannot burn a mega103 by
spi-programming
but as Jesper tells us: the 103 is the buggiest atmel part available...
I cannot copy that!
Double check with the help of pony-prog... this tool has saved some mine
devices
its live :o)
It's late and I'm drunk
