Hi@Yuri Muhin

 

Thanks for your response.

 

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 launch cameras (System stuck).

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

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

As well as I could figure out following. I have done some testing to narrow down the issue.


I can get videos using imxg2dvideosink which uses 2D GPU without any conflict. But when run imxeglvivsink which uses 3D GPU the system gets GPU hang. So it seems like 3D GPU section has damaged. But the reason is this system performed well 2 days without any conflict.


Can we imagine some thing happened to 3D GPU section ? What can be the cause of this issue ? According to my knowledge this looks like hardware problem. Do I have any thing to do to clarify this problem ?

 

Regards,

Peter.
