Bricked Atmega328p – kein Oszillator

English Version below

Ich hatte einige Atmegas 328p auf eine Platine gesetzt, ohne ein Oszillator oder Quarz mit einzuplanen. Eigentlich ist es wie ein Arduino auf einem Breadboard. Nun, zunächst sind die Fuses zu setzen und ein Bootloader zu installieren.

Ich habe dazu die Arduino IDE genutzt, einen Arduino Uno als ISP und einen Pro Mini als Target ausgewählt, ein Fehler wie sich herausstellen sollte. Ein Pro Mini hat ein Quarz, der 328p auf meiner Platine nicht. Nun, die Fehlermeldung bei den Fuses / Bootloader war stets:

avrdude: Device signature = 0x000000
avrdude: Yikes!  Invalid device signature.
     Double check connections and try again, or use -F to override
     this check.

Mausetot, leider!

Nun, nach einiger Recherche im Internet fand ich heraus, dass der 328p nicht mehr tut, da er ein Quarz erwartet. Aber es gibt Abhilfe. Man muss ein Signal auf XTAL1 geben um ihn wiederzubeleben.

Ich habe einen alternativen Arduino ISP Script von https://github.com/adafruit/ArduinoISP heruntergeladen und auf den Arduino Uno als ISP geladen. Dieser Script hat den Vorteil, dass auf PIN 9 ein Clock Signal ausgegeben wird. Dieses Signal habe ich dann auf den Target Atmega 328p XTAL1 mittels eines Kabels gesetzt. Ansonsten habe ich die übliche Verdrahtung gewählt:

Arduino UNO328p
D10Reset
D11MOSI
D12MISO
D13SCK
5V5V
GNDGND

Dann habe ich die Fuses so gesetzt, dass er mit internem Taktgeber läuft.

Fantastisch! Es hat geklappt. Das Kabel von PIN 9 konnte nun entfernt werden. Der 328p läuft nun mit internen Taktgeber. Dann schnell den Bootloader noch drauf.

Fantastisch. Damit war der 328p wiederbelebt und konnte nun den eigentlichen Script aufnehmen.

English Version

I had put some Atmegas 328p on a board without including an oscillator or crystal. Actually, it’s like an Arduino on a breadboard. Well, first the fuses have to be set and a bootloader installed.

I used the Arduino IDE for this, selected an Arduino Uno as ISP and a Pro Mini as target, a mistake as it should turn out. A Pro Mini has a crystal, the 328p on my board does not. Well, the error message on the fuses / bootloader was always:

avrdude: Device signature = 0x000000
avrdude: Yikes!  Invalid device signature.
     Double check connections and try again, or use -F to override
     this check.

Completely dead, unfortunately!

Well, after some research on the internet, I found out that the 328p doesn’t do more, expecting a quartz. But there is a workaround. You have to put a signal on XTAL1 to revive it.

I downloaded an alternative Arduino ISP script from https://github.com/adafruit/ArduinoISP and loaded it onto the Arduino Uno as an ISP. This script has the advantage that a clock signal is output on PIN 9. I then put this signal on the Target Atmega 328p XTAL1 using a cable. Otherwise I chose the usual wiring:

Arduino UNO328p
D10Reset
D11MOSI
D12MISO
D13SCK
5V5V
GNDGND

Then I set the fuses so that it runs with internal clock.

avrdude done.  Thank you.

Fantastic! It worked. The cable from PIN 9 could now be removed. The 328p is now running with internal clock. Then quickly put the bootloader on it.

Fantastic. With that, the 328p was revived and could now take up the actual script.
