Hi Renato,
I would suggest to start with the tutorial we have exactly for this usecase
here:
https://hub.mender.io/t/how-to-configure-networking-using-systemd-in-yocto-project/1097.
Once you have it replicated and working, add and modify the bits and pieces
that are specific to your requirements.
Greetz,
Josef
