IDE cant upload to Arduino Nano Every

I got a new Arduino Nano every and tried to upload a simple "Hello, World"- test Code.
I installed the the add on library for the board and selected the it.

unfortunately it doesn't work and i get the following error message:

avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description

I saw a few post on this forum about this Problem, but they all say i should ignore the message and the code should still work, but it doesn't!

Did you select the board from the boards menu and then select the correct com port from the Ports menu?

Hi @radamski

"They" were right. This warning message is not the cause of the problem.

We can help you with your problem, but only if you provide a detailed description:

  • What did you do?
  • What were the results you expected from doing that?
  • What were the results you observed that did not match your expectations?
