atmega32 / atmega8 Grundschaltung - Probleme mit avrdude (Invalid device signature)

[xrtm4e]

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:

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:

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.

Hast du mal die ISP Leitungen (MISO, MOSI, Reset, SCK) überprüft?

[xrtm4e]

Jep hab ich. Hab die Schaltung auch mal komplett neu aufgebaut, funktioniert immer noch nicht.

[joar50]

Spannungsversorgung am ATMega ist auch in Ordnung?

[trekko]

Jep hab ich. Hab die Schaltung auch mal komplett neu aufgebaut, funktioniert immer noch nicht.

Hilft es, den Programmer mit der avrdude-Option "-B 100" oder "-B 500" zu bremsen?

Hast du es mal versuchsweise mit einem anderen Programmer probiert? Vielleicht liegts ja an dem...

[xrtm4e]

Wenn ich die Baudrate kleiner mache geht gar nichts, dann antwortet der Programmer nicht. Wenn ich versuche ein Programm draufzuladen und die -F Option dazumache kommt folgendes:

Also der Ladebalken läd kurze Zeit (wie bei einer funktionierenden Schaltung) aber das Programm scheint nicht zu funktionieren (LED blinken).

Wenn ich die Baudrate kleiner mache geht gar nichts, dann antwortet der Programmer nicht.

Auch nicht bei der Option -B (groß B)?

Dann liegt es vermutlich wirklich an den Leitungen. Korrekt angeschlossen? Jede Leitung sicher verbunden (durchgemessen)? Kalte Lötstelle? Kurzschluss irgendwo?

Board ok?

Anderen Programmer probiert?
