Hi,
Under the Auto Linux for S32G, we understand that you already should have been a super-user, there is no need of sudo.
As for the specific information under S32G, we understand that there is no current guide for this. We do apologize.
We can recommend contacting your local NXP representative/FAE/DFAE (if any), to understand if under their channel there is any information available.
Again, we do apologize for the inconvenience.
Please, let us know.
