Some values not written into manufacturing.db

[jpiwek]

Hi,
why some values such as Ethternet MAC, Board were not written into the DB?
I am using CM4 Lite with 1GB RAM, without Wireless/BT.

That's a very curious error. I'll try and source a CM4Lite in that configuration to observe locally.

I have an tiny MCU on my carrier board which interfaces via uart to CM4 Lite.
I pull also specific data from that MCU e.g. serial#, firmware version. How to add additional colums to the Manufacturing DB and is there a hook where I can add that code to fill in that data?
