Dear Sir,

      I am loopback playing 1080P video on 1080P HDMI monitor on FSL SABRE-SD iMX6Q board, with following standard BSP versions w/o any modification,

          LTIB/ubuntu 10.04,   Yocto1.5, Yocto1.6, Yocto1.7

      The command is,

#! /bin/bash

while true


gst-launch playbin2 uri=file:///test/  audio-sink="fakesink" video-sink="imxv4l2sink axis-left=0 axis-top=190 disp-width=1200 disp-height=594"


         Every one to two hours, there will be a warning message in dmesg as below, and the HDMI montior will blank for about 1 second and become normal again.

             IPU Warning - IPU_INT_STAT_10 = 0x00080000

     I searched and read the relative topics on the community, and tried methods such as "dmfc=3", but it doesn't help. It seems that this is IPU bandwidth issue as the iMX6DQRM indicated, is there any SW update recentlly to address this issue?

     My project is blocked by this issue, and thanks a million for your kindly help!!!
