avrdude y atmega48pa

¿Puedo programar el atmega48pa con avrdude? Tengo problemas con la firma ...

% avrdude -pm48 -cavrisp2 -Pusb -V -U flash:w:main.hex

avrdude: Device signature = 0x1e920a
avrdude: Expected signature for ATMEGA48 is 1E 92 05
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

He agregado algunas líneas nuevas a avrdude.conf en / etc -directory

pero ahora me sale otro error

avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may not be reliable.

Pregunta

¿Puede alguien ayudarme a flashear un atmega48pa con un avrispmkii

Estás haciendo:

% avrdude -pm48 -cavrisp2 -Pusb -V -U flash:w:main.hex

Deberías estar haciendo:

% avrdude -pm48pa -cavrisp2 -Pusb -V -U flash:w:main.hex

Y en tu edición 1 estás usando la marca -p correcta y también parece funcionar. :)
