cvbs out (composite video) dont work.

find /sys/devices -name "edid"

/sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-HDMI-A-1/edid

find only HDMI out.

I replace meson-gxl-s905x-libretech-cc.dtb from this https://hub.libre.computer/t/lakka-for-libre-computer-boards/231

does it work with LibreELEC image?

ToKe79 commented 6 months ago

Also - I'm not sure if the dtb provided by Libre Computer for Lakka 4.2 is still compatible with Lakka 5.0.

without replace dtb: /sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-HDMI-A-1/edid /sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-Composite-1/edid

but need add option on boot line in file /flash/extlinux/extlinux.conf: console=tty0 video=Composite-1:720x480@60ie without this cvbs not work.

this solution find on libreelec forum https://forum.libreelec.tv/thread/26430-composite-video-output-on-aml-s905x-cc-le-potato/

@efirshik Lakka previously would only work on CVBS if we did not disable it in the DT. Thanks for testing.
