struthio

I got it working with the R2 rev00 device tree:
 
verbosity=4 bootlogo=false overlay_prefix=rockchip fdtfile=rockchip/rk3328-nanopi-r2-rev00.dtb rootdev=UUID=31d2bbea-e3ea-497d-a5cd-69a0d829f5fc rootfstype=ext4 console=serial earlycon=on usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u  
Ethernet, USB (including USB 3.0 and UAS, from what I see) work well, even GPIO devices show up. Not sure whether the missing UART output is related to the kernel upgrade or not. 1,500,000 baudrate assured, pins should have been attached correct, however at least the board is back up. We can ship the device tree switch for our users, but I can only encourage Armbian to re-enable the NEO3 device tree or find another way to prevent users from breaking their system, for reputation reasons. The NEO3 is a small board, but there will be some important production systems live as well, and there are always users who do not have an up-to-date SD card backup, in which cases they run into their personal GAU, without (working) debug console not even a way to get any related output of the failing boot 😉.
