@xiaoxiang781216 is it possible to create an image already with cmake-format to avoid the pip error? (error #11 https://acassis.wordpress.com/2023/06/20/nuttx-ci-github-failures-list/ )

It's possible if we create a dedicated docker image or reuse the one we used to build nuttx image.

Hi @raiden00pl @acassis
The cmake-format error has been resolved by PR #9864 , please rebase your code base and try again

I'm opening this PR.
Nordic configurations that use FetchContent_Declare() passed CI.
This PR must be merged first before updating testlist files - the Docker image must be rebuild.
