NONE OF THIS ALL!
There is essential info missing in the #PREFIX/etc/avrdude.conf file! I
copied a missing block from the mega162 to the mega163 block and now the
avrdude command succeeds (well... Partially; I get a verify error but
there is no 'avrdude: initialization failed, rc=-1' error anymore)

I was triggered by a posting earlier today about a wrong signature for the
mega8515 in 'avrdude.conf' and decided to start looking there. The
question is now: how reliable is avrdude.conf?????? Should it be compared
with the XML device files belonging to AVRstudio?

Any comments?
