Extra details

I’ve found an overlay for DEBIAN OS (official Redxa OS) that works, with this the display works well and also the touch screen.
rock-3a-radxa-5inch-touchscreen.dtbo.txt (999 Byte)
I’ve edited the extension to upload the file here.
I’ve copy and past this file ond the /boot/…/overlay/ and edited the dietpiEnv.txt file adding “overlay=rock-3a-radxa-5inch-touchscreen.dtbo” but nothing.

Hope someone can help me.

Thanks in advance.
