Prepare the Jetson

Prepare the Jetson for installation: confirm the JetPack release, stop the desktop from starting at boot, and keep the swap settings as they are.

Before you begin

Section titled “Before you begin”
  • A Jetson Orin Nano Dev Kit (8 GB) flashed with JetPack 7.2. To flash it, follow NVIDIA’s flashing guide.
  • Screen or SSH access to the device.

Check the JetPack release

Section titled “Check the JetPack release”

JetPack 7.2 ships the Linux for Tegra (L4T) R38 or R39 release, and the installer accepts both.

To check the release, run this command on the device:

Terminal window
cat /etc/nv_tegra_release

The release appears in the output as R38 or R39. If the output shows a different release, flash JetPack 7.2 before you continue. The installer stops on unsupported releases.

Trim the desktop

Section titled “Trim the desktop”

To stop the desktop from starting at boot, follow these steps. The change is recommended, not required:

  1. On the device, run this command:

    Terminal window
    sudo systemctl set-default multi-user.target

  2. Reboot the device:

    Terminal window
    sudo reboot

The desktop no longer starts at boot. SSH access works as before.

Keep the swap settings

Section titled “Keep the swap settings”

Keep the zram swap that the device already uses. Don’t add an SD-card swap file.
