Looking for some advice for dtoverlay on OrangePi 3B

General Discussion

Working with a DPI display and trying to set up overlay. I popped the dtbo file in /boot/rockchip/overlay/ dir.
I’ve also entered the following into the dietPiEnv.txt:

rootdev=UUID=57876797-a70c-4d51-bf42-c6eb94527443
rootfstype=ext4

The init system logs to the console defined last.

consoleargs=console=ttyS2,1500000 console=tty1
usbstoragequirks=
extraargs=net.ifnames=0
docker_optimizations=off
overlay_path=rockchip
overlay_prefix=rockchip
overlays=
user_overlays=
dtoverlay=rockchip/overlay/eleclab-dpi5inch.dtbo < (newly entered line)
fdtfile=rockchip/rk3566-orangepi-3b.dtb

I’ve been reviewing docs on the armbian env file, but am apparently missing something regarding syntax. I thought my issue was similar to: Dietpi v8.18.2 cannot load any overlays - #3 by Jappe, but it doesnt seem to be.

Thoughts? Maybe a board limitation/issue?

Apply the overlay statically to the base DTB and forget about your OS’s dynamic DTBO application framework:
fdtoverlay --input rk3566-orangepi-3b.dtb --output rk3566-orangepi-3b.dtb eleclab-dpi5inch.dtbo

I cannot find a source for the fdtoverlay command that you are referring to here. Is this a line in the Env file?

The fdtoverlay tool is a part of the DTC package.
It’s source is even included in any mainline kernel.
