Hi Oliver,

Thank you for your reply.

We are not getting the above three snaps listed even though we get through
the initial conf setup. So can you point to a possible error ?

We are populating the "authority-id" and "brand-id" fields in the json file
from the above link that you have mentioned i.e.

The "authority-id" field and "brand-id" is populated as "Account-Id" found
in the above link which is a 32-letter (Alpha-numeric).

Please do let us know if we are missing anything.

Also, as you mentioned that without proper authority id and brand id in the
assertion file, initial setup (before console-conf) will not happen. But we are
able to do the initial setup (profile setup) and then we get the shell prompt.

So can the initial setup be done if assertion model is not correct ?

If possible, this is to request you that if you can build the xenial sources (branch "snapdragon")
once and check if you are facing these errors like we are ?

We had only changed the snapcraft.yaml to get the dtb and firmware built.

Awaiting your reply.
