(1) Download and install system files on the host computer
First download two files from the NVIDIA official website:
Tegra186_Linux_R28.1.0_aarch64.tbz2
Tegra_Linux_Sample-Root-Filesystem_R28.1.0_aarch64.tbz2
Put these two packages on your laptop or desktop host, such as in the ~/rst directory.
Next, unzip and install
. Unzip Tegra186_Linux_R28.1.0_aarch64.tbz2
$ cd ~/rst
$ sudo tar -vxjf Tegra186_Linux_R28.1.0_aarch64.tbz212
After executing the command, a folder Linux_for_Tegra will be generated.
Then unzip the filesystem to Linux_for_Tegra/rootfs:
$ cd Linux_for_Tegra/rootfs
$ sudo tar -jxpf …/…/Tegra_Linux_Sample-Root-Filesystem_R28.1.0_aarch64.tbz2
[Tip]: If unsuccessful, prompt tar: : Not found in archive plus -C parameter installation, execute apply_binaries.sh in the ~/rst/Linux_for_Tegra directory.
$ cd …/
$ sudo ./apply_binaries.sh
(2) Install Realtimes-L4T-V202 driver
Download the Realtimes-L4T-V202 driver.
Install Realtimes-L4T-V202.
Extract the Realtimes-L4T-V202 package to the same directory as the Linux_for_Tegra folder:
$ mv Realtimes-L4T-V202.tar ~/rst
$ sudo tar -xzf Realtimes- L4T-V202.tar12
enters the Realtimes-L4T-V202 folder to install:
$ cd Realtimes-L4T
$ sudo ./install.sh
(3) Burn the system to TX2
First, let TX2 enter "Recovery Mode":
(1) Power off TX2 and unplug the power cord.
(2) Connect one end of the black USB cable of the accessory to the Host, and insert the other end into the USB port next to the WiFi antenna.
(3) Power on TX2 and plug in the power supply.
(4) First press the power button (PWR) and release it; then press the recovery button (REC) and hold it down; then press the reset button (RST), press and release it; wait 2 seconds and release the recovery button. Key (REC)
to burn the system to TX2, go to the Linux_for_Tegra directory to burn the system
$ cd ~/rst/Linux_for_Tegra
$ sudo ./flash.sh rtso-9003 mmcblk0p112
burning completed terminal display:
*** The target t186ref has been flashed successfully***Reset the board to boot from internal eMMC.12
TX2 Reboot into the system.
(4) Use Jetpack to install packages for TX2
There is no software development environment in the core board of the flashed machine. We need to use Jetpack to install the software environment. During installation, remove the items related to the operating system and install only the software environment. Run Jetpack on the host:
• Run the file, be careful not to use sudo to run it here.
$ ./JetPack-L4T-3.1-linux-x64.run
• Select the board, here select TX2.
• When the Host-Ubuntu and TX2 installation options appear, select Custom to install only the software package. Select no action for both the Host-Ubuntu and Flash OS Image to Target options. Select Install for the following parts of the Flash OS Image to Target option. Because these packages do not need to be installed on the host machine. As shown below:
click next.
• If you do not want to erase the Ubuntu system on TX2, you need to enter the IP address, user name, and password. These passwords are the account passwords of the Ubuntu system.
Note: Make sure the notebook and TX2 are connected to the same WiFi. The IP address that needs to be entered is checked by entering the ifconfig command on the TX2 terminal. The user name and password are both nvidia.
• Next, the installation options are prompted:
• Click next, and the Post installation terminal will pop up to start copying and installation.
• If the installation is successful, a message will appear:
Installation of target components finished, close this window to continue.
