Hi

We need more information to be able to help you with getting the project to build correctly here. Can you share some more information on the following:

1. Can you confirm you have the correct version of the Toolchain set for what SDK version you're building (NCS 3.1.0).
2. Are you building using VS Code and the nRF Connect extension or over the command line, and what is the build command exactly.
3. Share the full build log, as this is not sufficient to point out where the issue is exactly.

Best regards,

Simon

2. I am building vs code, NRF connect extension installed. zephyr files issue I am facing.

Okay, please upload the full build log so I can get a full picture. Also please confirm that you have all the necessary prerequisites to get started with the nRF Connect SDK. https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/installation/install_ncs.html#install_prerequisites 

Best regards,
