Hi! my friend has this chinese arduino nano that wont work and i have tried everything to help him but can't still get what's wrong. ive tried to read on a lot of forum, and did a lot of research, and i have come forward to think that it is the bootloader that wont install. i dont know if it is a bootloader on the nano allready, but i hope some of you have som suggestions.

Why are you burning the bootloader?

Please do this:

  • (In the Arduino IDE) File > Preferences
  • Check the checkbox next to "Show verbose output during: upload
  • Click "OK"
  • Tools > Burn Bootloader
  • After the Burn Bootloader process fails, you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • In a forum reply here, click on the reply field.
  • Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
  • Press "Ctrl + V". This will paste the Burn Bootloader output between the code tags.
  • Move the cursor outside of the code tags before you add any additional text to your reply.

You forgot to do the part of my instructions where I told you to set verbose output during upload.

Select Tools > Processor > ATmega328P (Old Bootloader) and then try uploading again.

I have a mixture of clone "Nanos", some of which have the 328PB processor on them. They use the "old bootloader" and I cannot change it for the later one even using a programmer which works on all of the other "Nanos" which have 328P processors

Which processor chip does your problem "Nano" have on it ?
