Displaying Graphics and Video on Component Output (hdcomp)

Amol Natekar

Hi all,

I am trying to display the matrix GUI on component output using the following commands as mentioned in DM816x_AM389x_VPSS_Video_Driver_User_Guide.pdf (Page 49)

         #/etc/init.d/matrix-gui stop

        #echo 0 > /sys/devices/platform/vpss/graphics0/enabled

        # echo 1:hdcomp > /sys/devices/platform/vpss/graphics0/nodes

        #echo 1 > /sys/devices/platform/vpss/graphics0/enabled

        #/etc/init.d/matrix-gui start

However there is no output displayed on Component. I even tried with DVO2 but no luck. Can anyone suggest how do I change my Display output for graphics as well as for video.

Thanks,

Amol
