Hi,

ich habe die Grundschaltung vom Wiki aufgebaut und habe ein Problem mit avrdude. Un zwar bekomme ich eine Fehlermeldung (mit einem mega32) die wie folgt aussieht:


Code:
avrdude: Device signature = 0x000000
avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.
Leider weiß ich nicht was das bedeutet. Hier mal die Ausgabe wenn ich folgenden Befehl eingebe:

Code:
avrdude -p m32 -c AVR910 -P /dev/ttyUSB0 -n -v -b 115200

avrdude done.  Thank you.
Bei einem mega8 lautet die Fehlermeldung:

avrdude: Device signature = 0xffffff
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

Was könnte ich dagegen tun?

Wäre sehr dankbar für Hilfe.
