Raxda Display 8 HD on Radxa ROCK 3A

[Iuri Jikidze]

I am trying to setup Raxda Display 8 HD with  Radxa ROCK 3A. On official Radxa OS, I used Rsetup tool to setup overlay for `Radxa Display 8 HD' using official guide. 

How can I do same on Dedicated applications images with Armbian Linux v6.12 ( Home Assistant ) ? 

 

I have read Device Tree overlays guide on armbian docs but I can't find overlay for lcd display in files:

Hi Iuri, I had a similar issue for the rock3a, but I'm using a BigTreeTech 5" DSI display for use on a 3d printer.  I've been dabbling in device drivers for 3 years with limited success, but I can say I recently got the 5" dsi display to work.  All of my work is here: https://github.com/saltydog101/rock3a_dsi  I had to load a new kernel module and then I was able to create a working dtbo for it.  It was definitely more than I expected.  That being said, when a vendor like Rockchip, Radxa or BigTreeTech decided to make a modification to the linux kernel and not have it committed to mainline, I don't think this is Armbian's issue at all.  The engineers and community here do amazing work getting linux running on so many devices.  You would normally have better luck looking at Radxa's discord and/or their documentation.
