DRM vivante GPU in imx6q

Hi team,

I am using the imx6qasbresd board with BSP version 5.10.7.2 and vivante version 6.4.3  and I am using the  X11 display server. I am trying to run the Qt5 GUI application or normal application then i am facing the segmentation fault there.

I checked all possible way for segmentation fault in openglwindows application as mentioned in the i.MX_Reference_Manual.pdf 5.3.11 Troubleshooting section but it did not work.

And CPU is being highly utilized, seems GPU is not being utilized.

make sure your kernel and GPU drivers are matched. == > I think  I am using the correct GPU driver version 6.4.3 as kernel version is 5.10 imx-linux-hardknott BSP.

what possibly I am missing? Does it needs the DRM initialization , I am not getting any print in the $dmesg | grep gpu 

the same application is working in the imx-linux-hardknott BSP, So I must be missing some configuration here may be in GPU init or library. 

Please help me in this issue.

Rk

Hello,

Your are connecting well the driver and gpu but with that kernel and BSP version it won't support X11, you need 4.1.15 at least to X11.
