Re: [avrdude-dev] Problem with AVR Dragon and ATmega324p on OSX

Joerg,

Thanks for the suggestions but I decided to update to Leopard (10.5)  
and all problems were gone.

I am using the latest avrdude 5.5. As a test, I tried to use avrdude  
5.3.1 and it didn't work in Leopard but fortunately 5.5 does.

Cheers,
Armin
