The driver is no longer compiled into the Image, but loaded into the system as a separate module. The dtb file is still compiled together as a whole to facilitate replacement.

The dtb can also be loaded dynamically as an overlay.

This method has the same goal as the method in the previous section, and one of the two can be chosen.
This method has the same goal as the method in the previous section, and one of the two can be chosen.
This method is complicated and not recommended for Nano, Xavier, Orin.
Specifically, for TX2 systems, only the methods in this section can be taken to upgrade.

During the Linux boot process, the cameras are detected in the order of i2c bus from smallest to largest. For example, if only one camera is connected, X is 0 regardless of the hardware connection to the location. If 5 cameras are connected, X is reflected as [0-4] according to i2c bus from smallest to largest.

In gstreamer command ，v4l2src has a param device=/dev/videoX to identify which camera to use.
