Arduino Nano Every stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

Using Arduino Avrdude, stk500, Bootloader issues

Dear Forum Members

Arduino 1.8.12
I am trying to get my Mac High Sierra 10.13.6 to download the code into Arduino Every.
I am able to read the Tools/Get Board Info window.
On downloading I still get the message:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

Any suggestions?

This error message indicates you have the wrong board selected. Despite the similar names, the classic Nano and the Nano Every are two very different boards. You need to install the boards platform for the Nano Every and then select that board when you are using your Nano Every:

  • Tools > Board > Boards Manager
  • Wait for the downloads to finish
  • Scroll down through the list of available boards platforms until you see "Arduino megaAVR Boards". Click on it.
  • Click the "Install" button.
  • Wait for the installation to finish.
  • Click the "Close" Button.
  • Tools > Board > Arduino Nano Every

Now try uploading again.
