Dear NXP,


I am working on Android 9 Automotive with IMX8QM. I am using LVDS to HDMI converter to connect between BOARD and Display.


  1. Connector name is not listed under /sys/class/drm:

      ls /sys/class/drm/

         card0 card1 version


     2. dmesg | grep -i HDMI
        console=ttyLP0,115200 earlycon=lpuart32,0x5a060000,115200 androidboot.console=ttyLP0 androidboot.xen_boot=default init=/init consoleblank=0 androidboot.hardware=freescale androidboot.fbTileSupport=enable cma=800M@0x960M-0xe00M galcore.contiguousSize=33554432 androidboot.primary_display=imx-drm firmware_class.path=/ vendor/firmware transparent_hugepage=never video=HDMI-A-2:d androidboot.wificountrycode=CN



Thanks & Regards,
