Hi Everyone
insmod ov5640_mipi.c module is loaded and it showing mipi is found but when we are trying to insert mxc_v4l2_capture.ko it showin ERROR: v4l2 capture: slave not found!
when i am trying this command
gst-launch-1.0 imxv4l2src num-buffers=300 device="$CAM-DEV" ! imxv4l2sink device=/dev/video17
Can't get caps from capture device, use the default setting.

Hi sindhuja,
It looks like there is no image data on /dev/video17, check if your ov5640 is running correctly, check the driver info:
# v4l2-ctl -d /dev/video17 --all
previous thread should be helpful:
