Camera driver porting, probe success but no /dev/video

I’m using Xavier AGX Orin develop kit and trying to make it works with imx477 camera sensor.
Between the develop kit, there is a expansion board with an I2C mux pca9548.
By modify the device tree, now I can see the pca9548 is working, the I2C can communicate with the imx477, and the nv_imx477 driver is loaded. But the issue that, there is no video device under /dev/video*, I would like to know if something missing or incorrect settings?

dmesg:

Hi Samuel,

I had the same problem moving from jetpack4 to jetpack5.
threads are the following:

the bottom line was to add “vc-id = 0” in the DTS and “vc_id = 0” in the mode sections.
in my case, I’m not using virtual channels so using 0 will work. I don’t know about your particular case though.

Hope this helps,
Alain

May need to trace into the tegracam_device_register() to figure it out.

Thanks
