 Hello i am a new arduino user. I have a working duemillanove arduino board with the atmega328p-pu .
I just bought two "Atmega168 20pu" chips without any bootloader so i made the following circuit into my breadboard.  h..p://arduino.cc/en/Tutorial/ArduinoToBreadboard

With the above circuit i get :
avrdude: stk500_getsync(): not in sync: resp=0x15

after searching over the internet i have found that
this error is because of Auto Reset capabilities of Arduino
source :

Now after adding the 120 Ohm resistor i get this error messge :
avrdude: Yikes!  Invalid device signature.
        Double check connections and try again, or use -F to override
        this check.

As board (tools options) i select "Arduino diecimila, duemillanove or nano w/ atmega 168". I am pretty sure that my circuit is correct.

What should i do ?

Thanks for your time !

Are you trying to upload a Sketch or install the bootloader?


I m trying to upload the bootloader.  :-/


You've uploaded the Arduino ISP sketch to the host arduino ?

Yes of course with success. I have also checked my breadboard circuit.

Using the command line:
"C:\Program Files\Arduino\arduino-0022\hardware\tools\avr\bin\avrdude.exe" -C "C:\Program Files\Arduino\arduino-0022\hardware\tools\avr\etc\avrdude.conf" -p m168 -P com5 -c avrisp -b 19200 -F

I get :
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA168 is 1E 94 06
