No valid hdmi video signal on RK3328

Hallo All,

Im try to port my mx10 box based on RK3328 to LE.

I extracted the dts from the android running OS and used with LE 9.0 (I compiled from the git master branch using the DEBUG switch).

Currently I'm able to complete the boot and I can connect the box using the samba and ssh, but I cannot get a valid video signal on the hdmi port.

I attach the dts I'm currently using and the System.log (here I'm enabled the dyndbg on the drm modules).

Can some expert give me some feedback?

In case I'm ready to run some additional test.

Thanks and bye.

Small update,

if I use the av (composite video) connector I can see the LE screen.

When I run:

LibreELEC:~ # cat /sys/class/drm/card0-HDMI-A-1/status

disconnected

LibreELEC:~ # cat /sys/class/drm/card0-HDMI-A-1/enabled

disabled

I also try the kernel boot arg

video=HDMI-A:e

video=HDMI-A-1:e

video=card0-HDMI-A-1:e

but I always get

LibreELEC:~ # cat /sys/class/drm/card0-HDMI-A-1/enabled

disabled

I found it.

I need to write video=HDMI-A-1:800x480@60e

Now the hdmi port is enabled and I get a valid video signal.
