Hello,
I am getting the following error whenever I run a code on Arduino Uno R3:
"avrdude: verification error, first mismatch at byte 0x0042
0x38 != 0x15
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch"
I am using Windows 10 and Arduino 1.8.5. Can it be that the microchip needs to be replaced, or the Arduino is no longer working?
Thank you
I would try burning the bootloader before I gave up on the chip. No guarantees, but I have heard of several being fixed this way. It's also a good thing to learn if you are going to play/work with Arduino's.
Hello,
Thank you for your response. I tried to install the bootloader using Arduino Mega as a programmer, but I got the following error:
"avrdude: stk500_recv(): programmer is not responding

This is how I tried to install the bootlader:
I am not sure why I got the error, but I noticed that the chip heats up very quickly. Did I make a mistake when installing the bootloader?
Thank you
- Connected the capacitor. Connected Arduino Uno to the computer
You should not connect the target Uno to the computer. The Mega (Arduino as ISP) is the one connected to the computer and the ISP leads connect to the UNO.
Try it again.
With the Mega loaded with the Arduino as ISP sketch and not connected to the UNO I get this.

avrdude done. Thank you.

Hello,
Thank you for your response. I did not connect the Arduino Uno to the computer to this time, but I got the following error message:
" ***failed;
avrdude: verification error, first mismatch at byte 0x0000
0x0f != 0x3f
avrdude: verification error; content mismatch
Error while burning bootloader."
I did the following:
Can it be that the issue is not with the boatloader? Can it be the chip?
Thank you
Hello,
Should I try replacing the chip of the Arduino Uno, or is the error because of how I tried to reinstall the bootloader?
Thank you
Should I try replacing the chip of the Arduino Uno
I would try it. You mentioned the chip was getting hot in one of your other posts. If you do change the chip, monitor the chip closely for heat. You shouldn't have anything connected to your Uno when testing except for the leads used to program it.
It would help next time if you showed more of the error message.
Select File/Preferences and the Tic the Show verbose output during: upload
Then select "Copy error messages"
Then paste into </> when you post.
