Dear All,

Hello. I tested the preview function on IMX6UL EVK.

But, the camera preview didn't work. There is some error messages.

Dear igorpadykov.

I checked "gst-inspect-1.0 imxv4l2src"

It showed the result as follows.

There is not available "Capabilities" configuration.

Please review logs and let me know how to solve it.
