I'm trying to boot my Nano Pi Neo 2 from the network but I am a bit stuck.

I have found out how to add network support to u-boot for the Nano Pi Neo 2, I can set the serverip and perform the dchp command, the Nanopi neo get's an IP address from the DHCP server but then booting halts with the message that it can't find the file. I'm pretty sure the location & access rights are valid. (Is there an easy way to check?)

Is there anyone who has experience  booting Armbian from the network that can point me in the right direction / perhaps share a working solution?

Did you tried a tftp client from another machine ?

ok, I tested from a different machine and it appears that the DHCP server shouldn't provide the fullpath of the filename, but just the path within the tftp folder.

After I changed the setting in my DHCP server the file could be loaded.

One step closer to booting the NanoPi Neo 2 from the network. I think my brain got a bit numb yesterday, by the end of the day

Does any one have a u-boot script in combination with Armbian to make this work with NFS?
