Reason for imx6q GPU hang ?

Hi All,

 

I encountered a problem with my iMX6Q custom hardware design with Linux version 4.1.15-1.0.0_ga+yocto+g76c24a0.

System was stable 2 days and worked properly for long time. Suddenly I encountered following problem.

 

I have an issue with GPU during I launch cameras (System stuck).

Camera launch >> gst-launch-1.0 v4l2src device=/dev/video0 ! autovideosink

Error message >> [galcore]: GPU[0] hang, automatic recovery.

 

It shows the test patterns without any conflict. When I run

gst-launch-1.0 videotestsrc pattern=0 ! autovideosink

There are no any conflict.

 

What can be the cause of this issue ? Will it be a DDR wrong memory calibration issue ?

 

Regards,

Peter.
