===Upgrade Jetson TX2, AGX Xavier and Xavier NX system===
==== Overview ====
This section describes how to upgrade the Jetson system to support our camera module. To support our camera module, we need to update the two parts of the L4T (Linux for Tegra) of the Jetson system, '''Image''' and '''DTB'''.
In the Image, we added the camera driver, while the DTB indicates the camera model used. In general, you only need to use the Image and DTB, that we have prebuilt, and you don't need to build from source when it is not necessary.
In particular, for Xavier NX, we provide a burning image of the TF card.

You can use the image prebuild by us to upgrade jetson nano system, which will support our camera.

==== Are Image and DTB upgrade successful ? ====
=====For Image=====
<code>ls /sys/bus/i2c/drivers/</code>
There should have veye327 csx307 cssc132 directory.
=====For DTB=====
DTB varies from platform and from camera module.
- TX2 Devkit
<code>ls /proc/device-tree/i2c@3180000/tca9548@70/i2c@*</code>
- AGX Xavier
<code>ls /proc/device-tree/i2c@3180000/tca9546@70/i2c@*</code>
- Xavier NX
<code>ls /proc/device-tree/cam_i2cmux/i2c@*</code>
You should be able to find the camera model you used.
