I want to run my scripts/progams automatically on boot on my Xavier, please kindly provide suggestion how to do it…
You will need to provide more information about the scripts. For example, if no GUI is required it is much simpler than with a GUI (or CUDA in need of at least a virtual GUI). If the script has to be run as a particular user, then that too matters. If networking must be up first, then this could matter. Anything you can think of your your use case should be described.
