Burning Bootloader on a Arduino UNO with another Arduino UNO

Development Tools Uploading
1

Hello guys,

I am a kind of newbie and I am in a dead end with my problem: I try to burn the bootloader on a Arduino UNO with the ATMEGA 328P with another Ardunio UNO in the same configuration (But as a replica from Elegoo). But it does not work. Here is the error message:

***failed;
avrdude: verification error, first mismatch at byte 0x0000
0x0f != 0x3f
avrdude: verification error; content mismatch

Anyone a guess what I am doing wrong?

Some background information:
How am I doing it?
I followed the instructions form this offical link:
https://support.arduino.cc/hc/en-us/articles/360012048080-How-to-burn-the-bootloader-between-two-Arduino-UNO
I made an additional step which is not descriped in the instruction: I choosed "Arduino as ISP" as programmer.

What is it doing?
I have the LEDs connected to check what the Ardunio is doing. The Heartbeat-LED is breathing constantly and when I burn the bootloader first the Error-LED flashes once and then the Programming-LED flashes once.

Why am I doing it?
I wanted to get a new script on the "target ardunio", but that did not work. The error message was something like:

avrdude: verification error, first mismatch at byte 0x0000
0x0f != 0x3f

Beside that the old script worked just fine.
So the internet adviced me to reburn the bootloader. I followed the above mentioned instruction and now, if I try to get a new script on the Ardunio I get the following error message after a long time of "uploading":

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x56

The old script does not work anymore.

Thank you in advance for helpful advices. I have reached the end of my wisdom.

Any chance you are using an older avrdude?
Is it failing while verifying Lock bits?
Use the command from an updated Arduino IDE like 1.8.13.
In Linux the avrdude you download lags behind the avrdude you get with the Arduino IDE.

Have you tried connecting a 10uF capacitor between the RESET pin and GROUND on the UNO being used as the programmer? Without the capacitor, the programmer board may reset during the programming cycle.

Thank you for the tip.
I use the actual IDE 1.8.13 which is provided in the Windows Store.
Unfortunately, I do not know exactly when it falis. Is there any possibility to get a better error message than:
***failed;
avrdude: verification error, first mismatch at byte 0x0000
0x0f != 0x3f
avrdude: verification error; content mismatch
?

Thank you for this info. I have put a 10µF capacitor between RESET and GROUND of the programmer UNO, but the result is still the same error message.
Any other guesses?

You may want to try the download from the Arduino site. Some people have had problems with the Windows Store.

Is there any possibility to get a better error message than:

File->Preferences->Show verbose output during:. Tick box for upload.J

I tried also the the IDE from the Arduino site: same issue

But here is a protocoll of the upload error when trying to burn the bootloader:

avrdude done. Thank you.

Maybe someone else?

And thank you very much for yout tips until now.

This might not help but can you make sure you have set board to Arduino Uno while uploading boot loader. You may try with
setting board as Arduino Duemilanove .Do check once what is exactly written on top of ATmega for the elegoo one.
After ATMEGA328p it would have something written like PU or AU .etc

First, I compared both chips:

  1. Arduino (the broken one):
    ATMEL(as logo) 35473D
    ATMEGA328P U
    181437M
  2. Elegoo (the one that should burn the bootloader):
    ATMEL(as logo) 35473D
    ATMEGA328P U
    2003Y7K
    I guess the last number is a serial number and it is the only number that is different.

I tried also to set the board as Arduino Duemilanove while uploading and/or while burning the bootlaoder. Uploading goes not even work, while burning leads to the exact same error message than above. I am really clueless. :frowning:

So now you are full of clues and not clueless.
As of I know arduino uno uses ATMEGA328P-PU and not ATMEGA328P-U.
Your problem has been earlier solved in this thread, have a look.
https://forum.arduino.cc/index.php?topic=564674.0
Alternatively you can have a look at this Burning the ATMega328p Bootloader and select your board accordingly while uploading.
Always check your IC information and then search.

Add Karma if you like :slight_smile:

My original Arduino Uno has been delivered with the ATMEGA328P-U.

Archut:

As far as I understand that right, the solution is to buy a new chip...

Archut:

It is written on this site that the MiniCore package only brings support for this ICs:
ATmega8
ATmega48
ATmega88
ATmega168
ATmega328
ATmega328PB

Archut:
Always check your IC information and then search.

Nevertheless, I tried with this instruction and it did not work. The errors are the same than in my previous posts. I tried the "AVR ISP (MiniCore)" and "Arduino as ISP (MiniCore)"-options.

It seems that my ATMEGA328P-U is broken. :frowning:
