Hi team,
I am using the imx6qsabresd board with custom kernel based on imx-linux-hardknott 5.10 and using the yocto Dunfell version.
I am trying to run the Qt application and getting the segmentation fault. I am using the prebuild libs of imx-gpu-viv_6.4.3. I am using the below libs.
ibCLC.so
libGAL.so
libGLES_CL.so.1.1.0
libGLES_CM.so.1.1.0
libGLESv1_CL.so.1.1.0

I am using the X11 window display. I am suspecting the segmentation fault is coming because of Dri failure as i am getting in X11.0.org

In the backtrace in gdb I am getting the below error,

Below is my imx-gpu-viv_6.4.3.bb file content.

Does this bb file needs the DEPENDS_append_imxdrm = " libdrm " ??
Could you please suggest what package or configuration is missing which is causing this segmentation fault.
Attached the Xorg.0.log. Please have a look into log.
