Hello Pablo,

thank you very much for these tipps. I'm now running 
Fedora-Minimal-armhfp-Rawhide-20180802.n.0-sda.raw.xz. I think, Fedora 
would be better for my need (pi-hole, DNS, Print-server, Time-server, 
...)

As I can see, there is a EMMC-disc with 8 GB. Did you manage to boot 
from this disc? At the moment, there is a older installation from 
linaro.

[root at cubietruckplus ~]# lsblk
