Nvargus cannot find camera while v4l2 works

Hello,
I am working on the driver of ov428+ochta10 camera on Orin32G. Here are the dtsi file about if.

I can get the raw image by v4l2 but the raw image seems no right.
When I try to use nvgstcapure-1.0. I get this log:

Have I make any misstake ?
Thanks.

Could be the devname incorrect.
If could be “ochta10 30-0036” confirm by v4l2-ctl --list-devices

Thanks for your reply.
It’s true that I have mistake in devname.
It can work now.
