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? Egbert Jan
