I got reported avrdude-5.5 present in Fedora 10 (and also Rawhide) does not support AT90PWM3. avrdude-5.6 is already released for a month, thanks.
current release of avrdude is 5.8 (released on 11-Jul-2009)
http://mirror.its.uidaho.edu/pub/savannah/avrdude/
version 5.8 includes support for atmega328p (which ver5.5 doesnt)
koji is building the 5.8 version for F11. I'll push it to the other branches later.
avrdude-5.8-1.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/avrdude-5.8-1.fc11
works for me, thank you! (:
avrdude-5.8-1.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report.
