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.

  • 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
