Have you checked the following? It seems that there's a version of the linux-dtb-legacy package without the the dtb files for the NanoPi M4 board, and the board won't start without one. I'm not sure if new images are shipping with that version or not and or even if this issue applies to non-legacy kernel. In any case, I'd suggest trying an older (archived) image of whichever variant your trying to use just to be sure (https://armbian.systemonachip.net/archive/nanopim4v2/archive/). CG
