This topic provides the steps to quickly get started using the L4T package with the Jetson TX 2 Developer Kit.
The most current Quick Start Guide for the Linux for Tegra Board Support Package is available at:
A Jetson TX2 Developer Kit
Your Jetson TX2 carrier board must be cabled as follows:
Serial cable plugged into the serial port on the target connected to your Linux host directly or through a serial-to-USB converter. This is required to setup serial console on the Linux host.
An Ethernet cable is plugged into the on-board Ethernet port.
An HDMI cable connects the carrier board to an external HDMI display.
(Not included in the developer kit) To connect USB peripherals such as keyboard, mouse, and USB/Ethernet adapter (for network connection), a USB hub must be connected to the working USB port on the system.
To download the latest release package
1. Download the latest version of the L4T release package and sample filesystem for the Jetson Developer Kit.
The package is available from the NVIDIA Embedded Developer Zone at:
If NVIDIA does not yet provide a public release for your Jetson Developer Kit, contact your NVIDIA Support Representative to obtain the latest release.
2. Untar the files and assemble the rootfs with the following commands:
sudo tar xpf $<L4T_RELEASE_PACKAGE>
cd Linux_for_Tegra/rootfs/
sudo tar xpf ../../$<SAMPLE_FS_PACKAGE>
cd ..
sudo ./apply_binaries.sh
<L4T_RELEASE_PACKAGE> is Tegra186_Linux_R27.0.1_aarch64.tbz2 for the Jetson TX2 release package filename.
<SAMPLE_FS_PACKAGE> is Tegra_Linux_Sample-Root-Filesystem_R27.0.1_aarch64.tbz2 for the sample filesystem package filename.
To flash the rootfilesystem to internal eMMC
1. Ensure you Linux host system is connected to the Jetson Developer Kit micro-USB port with a USB cable.
2. With the system powered on, place the Jetson Developer Kit into Force USB Recovery Mode as follows.
Press and hold the RECOVERY FORCE button.
While depressing the RECOVERY FORCE button, press and release the RESET (RST) button.
Wait 2 seconds and release the RECOVERY FORCE button.
3. Flash the L4T release onto the Jetson Developer Kit by executing the following command on your Linux host system:
sudo ./flash.sh $<platform> mmcblk0p1
Where <platform> is jetson-tx2.
The flashing procedure takes approximately 10 minutes or more on slower host systems.
Upon completion, the Jetson Developer Kit automatically reboots. The command prompt window opens on all display devices that are attached to the Jetson Developer Kit, and on the serial console.
The default login credentials are:
Username: nvidia
Password: nvidia
To install additional optional Ubuntu packages
1. Connect the Jetson Developer Kit to your wired network using a network cable.
2. Acquire an IP address.
If you are not running a graphical desktop environment that automatically configures your network connection, acquire an IP address with the following command:
sudo dhclient <interface>
Where <interface> is the name of the wired ethernet adapter for the Jetson Developer Kit's wired. Obtain the name by executing the following command:
ip link
The above command returns eth0, enx<mac_address>, or a similar name.
3. Install the package using the following commands:
sudo apt update
sudo apt install <ubuntu-desktop>
Where <ubuntu-desktop> is the name of the packages you wish to install.
4. Reboot the system using the following command:
sudo reboot
