Problem burning bootloader\ uploading sketch: avrdude: verification error; content mismatch

Hello everyone,

I have an Arduino clone from AzDelivery and try to reuse it. Since uploading a new sketch was not possible anymore I tried burning the bootloader again and uploading the standard 'blink' sketch.

I used an original UNO as programmer with help from this article. My programming setup is

In the past this was enough to get a 'clean' Nano. Uploading a sketch (after setting the IDE back to "AVRISP mkll") yields following result

I am not sure what this means. Is the bootloader burned correctly? Is the device ready for upload?

Googling yielded unsatisfactory results (result1, result2)

  • Multiple reburning had no effect
  • Reuploading the ArduinoISP sketch to the UNO had no effect
  • Rewiring had no effect

I burned and uploaded multiple Nanos today and one gives me troubles. Since some kind of communication is happening between the UNO and Nano (blinking while burning) I do not believe the device is lost, but can not figure out what the error is.

Nope !

I do have to reset my UNO at times to start the ArduinISP sketch again

If it's just that one, probably it is not working properly anymore and it's a hardware issue of some kind.

I also tried to upload the "Blink" sketch directly via the ISP

image

Setting the Board to the NANO
Setting the Port the the UNO (Programmer)
Programmer is still "Arduino as ISP"

Then upload using programmer: Upload successful!

The NANO still works!

How can I tell? The output does not return an error or a message that the wrong bootloader is loader.

I now flashed 15 Devices (cheap copies of a cheap copy) for my prototype CAN-network and everyone of them works fine:

  • Burn bootloader
  • Upload sketch via serial

The 'faulty' Nano is marked with ISP and will hopefully reused in another project

I have to bring the topic up again.

Over the weekend I sorted my uC's and wanted to check my unused original Arduinos (3xUnos, 5xNanos, 1xMega,...). The UNOs worked out of the box (example->Blink). The Nanos did not have a working bootloader since I was unable to upload any code. I tried both Nano-processors ATmega328P, ATmega32P (old bootloader) and even with the platform
UNO*.

Therefore I tried to burn the bootloader with the tutorials above. I tried the bootloader for

  • Atmega328P
  • Atmega328P (old bootloader)
  • UNO

avrdude done.  Thank you.

The output window acknowledges the process -> done burning bootloader.

None of the original Nanos were able to upload sketches after the burning of the bootloader. I tried every variation I can think of:

  • ArduinoIDE (burn as Atmega328P, old bootloader UNO)
  • VSCode w PlatformIO (burn as Atmega328P, old bootloader UNO)
  • On Win10, Ubuntu 20.04, Ubuntu 16.10

The results were the same -> unable to upload sketches via serial upload.

Now the odd thing: Programming the sketch via the UNO over ISP works. The serial monitor return the correct values also.

I am not sure if I am missing something or if there is a bug in the ISP-sketch or the burning process. I also have no indication that the burning process went wrong or that any of the hardware is defect.
