imx6q: Could not open egl display with Vivante GPU

Hi,

I've an issue while launching Qt5 application on imx6q

Boot Log:

------------

QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
 If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
Could not open egl display

I'm using opensource Linux, with following gpu drivers enabled.

drivers/gpu/drm/etnaviv/
drivers/gpu/drm/imx/

Kernel boot log with gpu drivers probe:

Please let me know if I miss anything here, the same rootfs with Qt5 is working fine with freesacle kernel.

Thanks.

Hi Jagan

in general for non-nxp kernels issues one can also post on

meta-fsl-arm mailing list, so that someone familiar with it could try to assist you.
https://lists.yoctoproject.org/listinfo/meta-freescale

Best regards
