Please check the remote-endpoint in nvcsi@{} vi@{} point to correct instance.
endpoint {
port-index = <0x00>;
bus-width = <0x04>;
remote-endpoint = <0x246>;
phandle = <0x2da>;
};
My original environment is SDK 32.6.1
The VIDEO device can appear normally and preview
But after updating to SDK 34.1, the video device cannot appear
Does the dts or driver need to pay attention to the modification??
The dts looks like was un-assemble from dtb so can’t tell if the remote-endpoint/phandle is correct or not.

Hi,I have the same problem. Has your problem been solved?
I can see tegracam_v4l2subdev_register function is ok…but can’t show /dev/video0 ???
In SDK 32.6.1 is fine …

For Orin need change the vi@xxxxx{} to tegra-capture-vi{} also the nvcsi@ could be different.

Please try with JetPack 5.0.2 GA release. Thanks
To clarify the problem
First use Xavier EVB to test
but still have problems
Next release should be coming soon at middle of August.
I would suggest to use imx274 dts as template to implement yours again.
