Dear @Werner ,
Thank you very much for your quick reply, and sorry for the delay on my end (I started a new job last week).
If this board is not yet compatible with Armbian, then why this article ?
EDIT: FriendlyElec's Wiki seems to imply that the board is compatible with Armbian's M6 / T6 and R6 images...
