Jetson AGX i2c(csi) camera driver problem

I am developing tc358743(Toshiba HDMI to MIPI-CSI bridge) driver with Jetson AGX xavier.
I would write a device tree(.dtsi) file for TC358743, and now I can see the TC358743 driver’s log in “dmesg”.
Based on the dmesg log, there seems to be no problem for drivers to communicate with the chipset and i2c.

[ 7.419377] tc358743 2-000f: tc358743 found @ 0x1e (3180000.i2c)

but, the problem is, I cannot see “Video0” in /dev directory,

dclab@dclab-desktop:~$ ls /dev/video*
ls: cannot access '/dev/video*': No such file or directory

Is the directory where /video0 appears in AGX board is different with another devices?
If it’s not, Somewhere in v4l2 init in driver maybe a problem, but I don’t know where to start check for debug.

Please let me know if you know what I missed.

Thank you.

hello userW,

please check Sensor Software Driver Programming Guide, please review sensor drivers probing process, which will the node as video device.
