Just for the record...
 
The image file I used to get my S905X3 box running was from this tutorial:
https://i12bretro.github.io/tutorials/0269.html
 
which references this site for the image file:
  https://drive.google.com/open?id=1n6CZa582uJECV3lzQDtFbmbyvmOSiUSg
 
The file is:
    Armbian_20.10_Arm-64_bullseye_current_5.9.0_desktop.img.xz
 
I used the dtb file  "meson-sm1-a95xf3-air.dtb"  from the Stable image referenced in SteeMans post.
 
This at least gets the board running and allows for an upgrade to the Debian Bullseye operating system using the apt-get command.
 
I can't get the current Stable images from the site referred to in SteeMans post here to work:
 
https://forum.armbian.com/topic/17106-installation-instructions-for-tv-boxes-with-amlogic-cpus/
 
Also the SHA checksums for these files don't seem to agree with the published value, so it may be there is some problem...
 
 
I hope this helps.
 

From what you have posted, I can't tell which Amlogic CPU your device actually has.
Do you have any additional information which would identify the CPU e.g. as:
S905
S905W, D, L
S905X
S905X2
S905X3

I updated my build environment and made a new build for CubieTruck using Buster minimal.
Booted the board multiple times and works every time.
Thanks for your help.
