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](https://dietpi.com/forum/t/dietpi-v8-18-2-cannot-load-any-overlays/17039/3), 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](https://github.com/dgibson/dtc).  
It’s source is even included in any [mainline kernel](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/dtc).

Thanks, I could not find the package based on the command. Its not in dietPi it would seem. I didnt find the binary.
