Ubuntu 24 (Jetson Linux 39.2 JetPack 7.2)

Note

1. The host system must be running Ubuntu 20 or later.

2. If `sudo apt update` reports an error, the host's package source may be the cause. Switch to an available source.

Jetson Linux 39.2 (Ubuntu 24)

A. Place the installation package on the Ubuntu host (your own host) and extract it:

unzip Amov_3920_Flash.zip

B. Install the environment automatically (see the Readme).

cd 3920_Flash

C. Follow JP3920_Readme.

Download the BSP packages:
https://developer.nvidia.com/downloads/embedded/L4T/r39_Release_v2.0/release/Jetson_Linux_R39.2.0_aarch64.tbz2
https://developer.nvidia.com/downloads/embedded/L4T/r39_Release_v2.0/release/Tegra_Linux_Sample-Root-Filesystem_R39.2.0_aarch64.tbz2
(Place the SDK package and 3920_Flash in the same parent directory.)

Set up the environment:
1. Run:
	tar xf Jetson_Linux_R39.2.0_aarch64.tbz2
	sudo tar xpf Tegra_Linux_Sample-Root-Filesystem_R39.2.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
	cd Linux_for_Tegra/
	sudo ./tools/l4t_flash_prerequisites.sh
	sudo ./apply_binaries.sh
	sudo tools/l4t_create_default_user.sh -u amov -p amov -a
        Select <Accept>

2. Replace the dtb and Image in the official Linux_for_Tegra/kernel/ directory with dtb.tar.gz and Image.
cd -
cd 3920_Flash
cp Image  ../Linux_for_Tegra/kernel/
sudo tar  xpf dtb.tar.gz   -C ../Linux_for_Tegra/kernel/

3. Replace Linux_for_Tegra/rootfs/ in the official package with boot_3920.tar.gz.
sudo tar  xpf boot_3920.tar.gz  -C ../Linux_for_Tegra/rootfs/
sudo tar  xpf 6.8.12-tegra.tar.gz  -C ../Linux_for_Tegra/rootfs/lib/modules/
sudo rm -r ../Linux_for_Tegra/rootfs/lib/modules/6.8.12-1021-tegra

4. Place the applications in the root file system.
sudo chmod 0777  rootfs/*
sudo cp rootfs/*  ../Linux_for_Tegra/rootfs/usr/bin
sudo cp amov.jpg  ../Linux_for_Tegra/rootfs/usr/share/backgrounds/NVIDIA_Wallpaper.jpg


5. Flash the system.
cp jetson_orin_flash.sh ../Linux_for_Tegra/
cp jetson_orin_flash_super.sh  ../Linux_for_Tegra/
cd ../Linux_for_Tegra
sudo chmod 0777   jetson_orin_flash.sh
sudo chmod 0777   jetson_orin_flash_super.sh


Put the onboard computer into REC download mode:
	1 Put the onboard computer into REC mode.
	2 Turn off power to the system.
	3 Use a USB cable to connect the ORIN OTG-USB port to a USB port on the Ubuntu development host.
	4 Press and hold the REC button, power on the system, keep holding the button for at least 3 seconds, and then release the REC button.
	5 Enter lsusb in the host terminal. If an NVIDIA device is displayed, the device has successfully entered Recovery mode and subsequent operations such as flashing and backup can be performed. If no NVIDIA device is displayed, check the cable and the procedure for entering the mode, and then try again.

Standard mode
./jetson_orin_flash.sh
Super mode
./jetson_orin_flash_super.sh
