3.4  Connect a monitor, keyboard, and mouse to the Jetson AGX Orin DevKit, then power on both the Jetson AGX Orin DevKit and the GMSL camera deserializer board

4.  Loading the Precompiled Driver File

4.1   Check JetPack Version

Run the following in the terminal:

dpkg -l | grep nvidia-l4t-core

From the output, check the corresponding JetPack version using NVIDIA’s JetPack-L4T mapping table

(Example: Output nvidia-l4t-core version 36.4.3 corresponds to JetPack 6.2)

4.2   Obtain the Precompiled Driver

Download gmsl-driver-jetson-vx.x.x(JPx.x).zip from the GitHub repository and place it in the ~/Downloads directory

Fig. 4-3

4.3  Extract and Install

For GMSL camera deserializer board FG96_8CH_GMSL(EVK), use the copy_to_target_agx_orin_fg96.sh script

Run the following in the terminal:

cd ~/Downloads/
unzip MIPI_Camera_Platform_Driver.zip
cd gmsl-driver-jetson-v1.2.03(JP6.2)/
chmod +x copy_to_target_agx_orin_fg96.sh
sh copy_to_target_agx_orin_fg96.sh
reboot

5.  Getting Started

5.1   Check Driver Version

Ensure the driver version matches the precompiled driver file version

Run the following in the terminal:

cat /sys/module/g300/version

Fig. 5-1

5.2   List Video Nodes

Run the following in the terminal:

ls /dev/video*

Note: One Gemini 335Lg camera will generate 8 video nodes:

• video0 – Depth stream
• video1 – Depth metadata
• video2 – Color stream
• video3 – Color metadata
• video4 – Left IR stream
• video5 – Left IR metadata
• video6 – Right IR stream
• video7 – Right IR metadata

Fig. 5-2

5.3   Obtain OrbbecViewer Software

Download the latest OrbbecViewer from OrbbecSDK_v2 Releases (e.g., OrbbecViewer_v2.4.8_xxx.zip) and place it in ~/Downloads.

Fig. 5-3

5.4  Extract and Run

Run the following in the terminal:

cd ~/Downloads/
unzip OrbbecViewer_v2.4.8_202507031357_a1355db_linux_aarch64.zip
cd OrbbecViewer_v2.4.8_202507031357_a1355db_linux_aarch64/
sudo ./OrbbecViewer
