Odroid-C4 dtb question

[scjet]

I successfully installed CE 9.2.5 on my Odroid-C4’s eMMC, and it seems to be booting and running fine.
But according to your “DTB” instructions https://coreelec.org/dtb/ my device_tree dtb is: “sm1_s905x3_odroid_c4”
on my Odroid-C4 with CE9.2.5;
The ONLY file I found with “sm1_s905x3_odroid_c4” in it is:

cat /proc/device-tree/coreelec-dt-id
sm1_s905x3_odroid_c4

Am I supposed to copy that file to the “root” folder and rename it dtb.img ?

cp /proc/device-tree/coreelec-dt-id /dtb.img
cp: can't create '/coreelec-dt-id': Read-only file system

or, should I remount my Odroid-C4’s coreelec eMMC onto my eMMC-to-USB3 adapter on my Desktop, and “cp /proc/device-tree/coreelec-dt-id /dtb.img” ?

Odroid device img.gz do included already the correct dtb.img.
Without it the device would not boot at all.
So nothing todo…
