Setting up the burning environment 1)Copy the above required files to the same directory of the burning host 2)Unzip the Linux Driver Package $ tar –jxvf Jenson_Linux_R<version>_aarch64.tbz2 Generate the folder directory Linux_for_Tegra 3)Set the root file system 1. Enter the root file system directory of the Linux Driver Package $ cd <your_L4T_root>/Linux_for_Tegra/rootfs 2. Unzip the Root File System $ sudo tar -jxpf ../../Tegra-Linux-Sample-Root-Filesystem_R<version>_aarch64.tbz2 4)Install the BSP support package 1. Decompress the Realtimes_L4T_Xavier_<version>.tar.gz package to a directory at the same level as the Linux_for_Tegra folder $ tar -xvf Realtimes_L4T_Xavier_<version>.tar.gz 2.

Flash System Note：Realtimes_L4T_3261_xavier_V1.4.tar support Xavier industrial module Before burning the system, set the Xavier device to the recovery mode. For the method of entering the recovery mode, refer to the RTSO-1001 user manual 1) Realtimes_L4T_Xavier_3271 method of flash system: $ sudo ./realtimes-flash.sh // Select the module and flash the system 2) Realtimes_L4T_Xavier_3261(Xavier_3251)method of flash system: Xavier module(32GB eMMC)： a.$./realtimes-flash.sh //Select the Xavier module b.$ sudo ./flash.sh jetson-xavier mmcblk0p1 //flash system Xavier industrial module(64GB eMMC)： a.$./realtimes-flash.sh //Select the xavier industrial module b.$ sudo ./flash.sh -S <size> jetson-agx-xavier-industrial mmcblk0p1 //flash system<size> Indicates the size of rootfs For example:Set the rootfs size to 50GB，50GB=1024*1024*1024*50=53687091200sudo ./flash.sh -S 53687091200 jetson-agx-xavier-industrial mmcblk0p1 If <size> is not specified, the default value is 32GB For example：Run realtimes-flash.sh, select Xavier module,Select '1' to exit the script automatically 3) Realtimes_L4T_3243_Xavier and earlier versions flash systemmethod： $ sudo ./flash.sh rtso-1001 mmcblk0p1 //flash system The method of Xavier Feiyun Smart Box to flash the system is the same as that of RTSO-1001.For the method of entering recovery mode, see Xavier Feiyun Smart Box. After the system is flashed, Jetson device will start automatically. If it is connected to a display, the GUI system initialization interface will appear after the startup, including user creation and language selection, etc., and configure according to the prompts. ## System Upgrade Note: It is not possible to upgrade the system directly by running "sudo apt upgrade" or other system upgrading methods. In this way, the current L4T system version will be directly Realtimes Beijing Technology Co.,LTD www.realtimesai.com 9 / 19 Xavier System flash manual V1.3 upgraded to the latest version, and the previous kernel and kernel-DTB will be upgraded to the kernel and kernel-DTB of the development suite.The onboard interface is unavailable. If you need to upgrade the "upgrade" system, you can lock the kernel and kernel-dtb file to prevent the upgrade. However, this method can only be applied to the system upgrade between"point release" and the GPU driver is not upgraded. 1 Jetson prohibits specified software and L4T system upgrades: 1)Disabling Software Upgrades ``` sudo dpkg --get-selections | more //Check the status of all software in the systemsudo apt-mark hold nvidia-l4t-kernel //Disabling Kernel Upgrade sudo apt-mark hold nvidia-l4t-kernel-dtbs //Disable the kernel-dtb upgrade sudo dpkg --get-selections | grep hold //Check whether the lock is successful ``` 2)The L4T system upgrade is cancelled example：Jetson L4T R32.4.x System setting →softwore&Updates→other Software Uncheck the“...r32.4 main”
