Thanks for reply, I solved my problem. There is clock issue in block design, after this I am successfully captured 14 images from mipi camera.
I have another issue regarding about frame buffer device. /dev directory is not showing any /dev/fb0 device
boot log for xilinx drm driver as follows

Hello folks,
I am running Zybo Z7-20 Pcam petalinux project on Zybo Z7-20 board.From README.md file below command will create 14 image files in current directory
yavta -c14 -f YUYV -s "$width"x"$height" -F /dev/video0
when we test similarly our log stucks as per below
root@test0:~# yavta -c1 -f YUYV -s "$width"x"$height" -F /dev/video0
Device /dev/video0 opened.
Device `video_cap output 0' on `platform:video_cap:0' is a video output (without mplanes) device.
Video format set: YUYV (56595559) 1280x720 field none, 1 planes:
* Stride 2560, buffer size 1843200
Video format: YUYV (56595559) 1280x720 field none, 1 planes:

when we run media device information command(media-ctl -p)
we get following log

Hello @Gumesh
I used the custom zynq board. where i was configured wrong pin in xdc file.
