[CMD] avrdude results in error (not in sync). Even programs can be uploaded

Hello,

I got my Arduino Uno Rev. 3, ATmega328 today and would like to use it to flash some ATMEGA8 chips. So far I can compile, upload and execute programs using the Arduino debugger/programmer tool.
I’m following this guide in order to flash some ATMEGA chips.

But I’m stuck at step 3 where it tells me to execute the following line via CMD:

avrdude -p m8 -b 19200 –B 4 -c avrisp -P COM1

I changed it to COM3 since this port was auto-selected by the Arduino Debugger.
I can communicate with the Arduino Board. But I get the following error:

avrdude: stk500_getsync(): not in sync: resp=0x00

I googled a lot and tried unplugging the board, changed the COM Port and so on.
After that I tried some troubleshooting on CMD. Entered another device value (one that fits my board). I was unable to connect at all (since no COM was defined).
But as soon as I define the right COM (meanwhile it’s COM6) I get the same error from before.

avrdude -p m328p -c avrisp -P COM6

Any idea?

Try “stk500v1” where you currently have “avrisp”. Add “-vv “ for additional debug info

This gave me the following:

C:\Windows\system32>avrdude -p m328p -c stk500v1 -P COM6 -vv

avrdude done. Thank you.

What are you using as isp programmer? If it is an arduino, did yoj remember to upload arduini as isp sketch to it?

avrisp mkll

And you own an AVRISP MkII and have connected it to the ISP pins of the target processor?

What are you using as isp programmer?

avrisp mkll

In that case, I take back what I said about using “stk500v1” - from your initial post, I assumed that you were using the Uno as a programmer…

should I burn the bootloader or something?
I just did the exact same as told in the guide

Well, I have uploaded the ArduinoISP script and after executing:

avrdude -p m328p -c stk500v1 -P COM6 -vv

I've got the following:

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

avrdude done. Thank you.

Still don't get the signature of my chip on the bread board. As soon as I connect the reset wire I get the not in sync error again.

EDIT: I had to wire the reset wire to PIN 10 and got the following:

avrdude: Device signature = 0x1e9307
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.

avrdude: Device signature = 0x1e9307

That matches an ATmega8, so that's good news.
To program the atmega8 you need the "-p m8" that you had initially...

Did that, everything worked fine :slight_smile:
Thank you
