Can't get image from PCam 5C running on Zybo Z7-20 with petalinux

[shantaramj]

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.

from this we are not sure whether the images created or not.

The functions above will create 14 image files in your current directory.

Probably term `functions` is misleading it should be commands.

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

Hi @shantaramj

Can you please confirm if you used the  Zybo Z7-20 Pcam petalinux project in v2017.3/4 or upgraded it to v2019.1.
I am trying to do the same but validating the vivado design is giving me errors.

If you built in v2019.1 can you please let me know how?.
Thanks in advance, your time and help is highly appreciated.

Hello @Gumesh

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