You may have seen my topic on the old forum : http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1294997078
To reassume i have two "Atmega168 20pu" chips without any bootloader
I have tried three methods to put the bootloader
a) using arduinoisp with 16 mhz crystal
b) bitbang mode
c) using usbtinyISP

on all of these methods i get :
avrdude: Yikes!  Invalid device signature.
        Double check connections and try again, or use -F to override
        this check.

using avrdude from 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

same are the results using winavr...

Run this...

Code:

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 -v -v -v

Post the results.  Please use code tags.

There you go . I am using usbtiny.

Code:

"C:\Program Files\Arduino\arduino-0
022\hardware\tools\avr\bin\avrdude.exe" -C "C:\Program Files\Arduino\arduino-002
2\hardware\tools\avr\etc\avrdude.conf" -p m168 -c usbtiny -b 19200 -v -v -v

avrdude.exe done.  Thank you.

Using usbtinyISP i can read with success my original atmega 368 bundled with my arduino duemillanove.
Thanks

Do you have a 16 MHz crystal connected to the 168 processor?

[Reply #4 on:]

yes of course ...

[Reply #5 on:]

It looks like the 168 processor is not responding to the programmer.  I know that doesn't help but, unfortunately, it's all I have to offer.  You've proven the programmer and software are working.  I cannot think of anything else to try.

Hello again and thanks to all for your support and feedback !
I have sent back the two ATMEGA 168 and i got back two others from the same seller.
Now everything works like a charm.
The first one i have put the bootloader using usbtiny + arduino (without the usb cable) with the ICSP cable. No problems at all i just used the arduino gui normally.
The second one i have used the usbtiny with my handmade arduino breadboard. I only pressed the reset button once then the bootloader was successfully loaded via the arduino gui.

So it was so simple that i did not even use avrdude directly but only within arduino GUI

Thanks !
