HDMI doesn't work for rk3568 on some displays

[kostprof21]

I am using kernel 6.12.45 with rk3568 , everything is displayed on my monitor. A colleague's computer does not work on 3 of the 4 monitors. the error is the same as in the theme

/

kernel: rockchip-drm display-subsystem: [drm] Cannot find any crtc or sizes

, since it seems that no one is watching that topic, I decided to raise this issue. Has anyone encountered such a problem?

Radxa Zero has a different soc: https://radxa.com/products/zeros/zero/

Double-check what hw you actually have

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

Hi Werner
I apologize for radxa zero, as I do not know which tag to choose. I have a board based on OK3568 from Forlinx.

The board I have has a different Rockchip SoC (rk3588-orangepi-5-plus), but it's been my experience that the edge kernel (6.16) is the only one that's of any real use to me. I get no video with the "current" (6.12) kernel, and no GPU acceleration with the vendor (6.1) kernel.

 

So I would suggest just switching to the edge kernel.
