Hi,

For debugging, I suggest that you use Our VS Code extension.
You should still be able to use "west debug", but if the VS Code extension solves the issue for you, then lets not dig down into debugging

I am sorry! I don’t like to use vscode.

Let's look into what is wrong here then.

How did you install the nRF Connect SDK?

Can you program nRF Chips? If yes, how do you do this?

I use "west flash" command to flash chips.
