Nanopi R6_
Nanopi R6C / R6S are nice boards, especially the multiple RJ45 make them stand out. The boards are shipped with u-boot without EFI support. Booting EFI partitions therefore requires recompiling u-boot and overwriting EMMC memory. The Nics connected via PCI dont have their MAC burned to the Nic. When not using friendlyelec Linux fork setting up interfaces on PCI Nic requires grabbing the MAC from u-boot environment variables or making one up, then setting it manually.
