How to setup Jetson Xavier NX production module?

[justahuman]

Hello,
can someone please help me set up my Jetson Xavier NX “Production” kit?

if you can help me with any resources, that would be really helpful.
I am mainly looking at the following points:

1. My main system is on SSD, so how to maximize its use, and remove any redundant packages while enhancing its performance?
2. Security-wise, are there any methods to secure it so that no one can enter inside the jetson? (apart from password security any other methods ?) (I can’t turn of the display as I need the display in production)
3. any external packages to increase the performance?

I am setting this up for the first time, please help me with the proper resources/references.

thanks in advance

Hi,

1. Refer to the following link for removing unnecessary packages:
   Storage Optimization — Jetson Linux Developer Guide documentation
   But unless your SSD is near full (like usage is over 80% or 90%), you usually don’t get extra performance by deleting files in it.
2. Over the Internet, I think SSH should be safe enough. Physically, except locking your device in a safe, I don’t there’s a better way to protect it than passwords.
3. Check /etc/nvpmodel.conf to find the most powerful power setting for your device, and use sudo nvpmodel -m X to set the power mode. To squeeze more computing power, run sudo jetson_clocks so your device always runs at the highest frequency previously set with nvpmodel.

Thank you @DaveYYY for your promt response.

1. and 3rd are clear.

as per 2nd, I read on a few forums regarding security that there is a provision to burn some keys and secure your module.

as I am working on a production module, could you please suggest or clarify those for me in simple steps for new comers?

There’s a bunch of different features regarding security in L4T, and you’d probably need Secure Boot, which prevents your device from booting with unauthorized code.
