The bitimage variable needs to contain the full path to the *.rbf file you 
compiled and placed somewhere on the sd card ie: 
/boot/DE10_Nano_SoC_FB_DB25.rbf
(this assumes you copy the current test subject file you quartus compiled 
from the output_files folder to /boot folder on the sd card)

No no no
where are you getting soc_system.dtb from ... not my instructions.

You need to use a sutable kernel compiled .dtb file from the /boot/dtb 
folder. (name something like: DE10_Nano_FB).
The exact same dtb file as named in the instructions for the demo image... 
OK ?
