Alpine Linux on NanoPi R6S - eviltoast

Hey everyone, I’m looking to replace my router with a NanoPi R6S but want to do everything myself from Alpine Linux.

I’ve been doing a lot of research and it seems that the chipset and hardware are supported as of Linux 6.3, but looking at Alpine’s ARM documentation makes installation sound a bit more advanced than I’m used to (specifically, the partition layout and U-Boot are confusing to me).

Has anyone gone this route?
