Can't burn sketch with arduino-0011

I've been using arduino-0009 without any problem. Today i've installed 0011 and problems have come.

I can't burn any sketch, i get this error always:

Binary sketch size: 3184 bytes (of a 14336 byte maximum)

avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

The same sketch can be burn with 0009 version.
Help please!

Are you sure you have chosen the right board in the tools -> microcontroller menu? I don't think each version of the IDE remembers your settings from previous versions

yeah, arduino is selected :-/

i really don't know why it works on arduino-0009 and not in 0011
grrrr

Yep but is it the RIGHT arduino?

Serial, NG, Decimelia, Lilypad etc...

sure, it's decimilla.
I'll stick to 0009 since it's working :S

solved in this another thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1202087650

it was an amd64 related problem, edited source code to add a "-F" flag and compiled again.

working right now :slight_smile:
