    Study Notes

    Jetson Linux Quick Start

    • NVIDIA Jetson developer kits support software development and testing.
    • Jetson modules are intended for production deployments.
    • Jetson modules ship without pre-installed software and require a carrier board for use.
    • Jetson developer kits include a non-production Jetson module on a reference carrier board, and are ideal for software development and testing.
    • Jetson modules are suitable for production environments throughout their operating lifecycle.

    Jetson Devices Supported

    • NVIDIA® Jetson AGX Orin™ modules and Jetson AGX Orin Developer Kit
    • NVIDIA® Jetson Xavier™ NX series modules and Jetson Xavier NX Developer Kit
    • NVIDIA® Jetson AGX Xavier™ series modules and Jetson AGX Xavier Developer Kit

    Preparing a Jetson Developer Kit

    • Requires a Linux host and a compatible Jetson developer kit.
    • Connect the host to the Jetson developer kit using USB (USB-C for AGX Xavier, micro USB for other kits).
    • Connect any necessary USB peripherals (keyboard, mouse, etc.)
    • Establish a wired Ethernet connection for optional software installation.
    • Connect a display device or a serial console (e.g., a terminal program on the host).

    Environment Variables

    • ${L4T_RELEASE_PACKAGE}: Path to the Jetson Linux release package.
    • ${SAMPLE_FS_PACKAGE}: Path to the sample file system package; value depends on the Jetson model. Specific values are given. e.g., Tegra_Linux_Sample-Root-Filesystem_L4TRELEASEVERSION.tbz2.
    • ${BOARD}: Name of the configuration (e.g., jetson-agx-orin-devkit), specific values given. Example: jetson-agx-orin-devkit.

    Flashing Jetson Linux

    • Download the latest Jetson Linux release package and sample file system.
    • Untar the released files.
    • Assemble the root file system.
    • Run the apply_binaries.sh script.
    • Enter force recovery mode on the Jetson developer kit.

    Entering Force Recovery Mode (Jetson Xavier NX)

    • Power off the Jetson Xavier NX Developer Kit.
    • Insert a 16GB+ microSD card.
    • Place a jumper across pins 9 and 10 (FC REC and GND) on the button header (J14).
    • Connect the power adapter.
    • Remove the jumper.

    Entering Force Recovery Mode (Other Jetson Kits)

    • Power off.
    • Press and hold the Force Recovery button.
    • Press, then release the Power button.
    • Release the Force Recovery button.

    Determining Force Recovery Mode (lsusb command)

    • Connect the host.
    • Run lsusb on host. Detect a specific USB ID. Example: Bus Device : ID 0955:7023 ... Nvidia Corp.

    Installing Jetson Linux using flash.sh

    • Run the command sudo./flash.sh ${BOARD} mmcblk0p1 on host. Specific BOARD value required.
    • Jetson kit reboots after installation.
    • Set up user account and log in.

    Jetson Modules and Configurations

    • Specific configurations: model, type (development or production), carrier board, configuration (name), and storage device flashed.
    • Each configuration has a corresponding .conf file. (e.g., jetson-agx-orin-devkit.conf). Example configurations and associated data for particular modules given.
    • Development modules are only sold as part of a kit. Production modules are intended for use in production, and often sold separately. Development and production modules also available individually.
