Using Jetpack TX2 with Balena - Jetson TX2

Hi, I am newbie with Jetson TX2. I have installed JetPack 4.2 ont TX2 and as the next step I need to run my python code with two RGB-D cameras on it. Do I need to install Balena? Does balena go with jetpack 4.2 or I need to install the older version of jetpack? Many thanks.

What’s is Balena? It’s a USB camera?
For the MIPI sensor you may need to check the document to implement the sensor driver.
