HDMI is not detecting in IMX8QM

[vinothkumars]

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,

Hi, 

HDMI is working properly after flash 

"android_p9.0.0_2.1.1-auto-ga_image_8qmek2" this images instead of "android_p9.0.0_2.1.1-auto-ga_image_8qmek".

Hi VinothS,

I’m afraid that the i.MX8QM is still on preproduction, and you need to contact with your Sales or FAE in case of requiring support.

Additionally, Android Auto is supported under “Commercial Support and Engineering Services” scheme. You could refer to the following link for additional details:

Commercial Support and Engineering Services | NXP 

Hope this will be useful for you.
Best regards!
