  • Port 3 and 4 … NG

  • Port 1 and 5 … OK

1.4.4. Power ON and Login#

Power On

Power on the EAC-5000 and confirm that the power-on LED illuminates blue.

Login

Please log in using the username and password configured during the BSP flashing process.

1.4.5. Camera Driver Installation#

Note

Please note that camera operations are currently confirmed only on Port 1 and Port 5. Fixes for other ports are currently in progress.

This process should be performed on the EAC-5000.

Step 1: Download the Driver

Open a terminal on the EAC-5000 and run the following command to download the driver package.

wget https://github.com/tier4/tier4_automotive_hdr_camera/releases/download/v2.2.0/tier4-camera-gmsl_2.2.0_arm64.deb

Step 2: Install the Driver

Execute the following command in the directory where the downloaded .deb file is located to install the package.

sudo apt install ./tier4-camera-gmsl_*.deb

Step 3: Configure the Device Tree

Note

For advanced configurations, including how to connect a combination of different camera types, please refer to the camera driver’s GitHub page.

After installing the driver, you need to generate a custom .dtb file to define the assignment of cameras for each GMSL port. Run the command corresponding to your camera type:

  • C1

    sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="TIERIV GMSL2 Camera Device Tree Overlay: C1x8"

  • C2

    sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="TIERIV GMSL2 Camera Device Tree Overlay: C2x8"

  • C3

    sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="TIERIV GMSL2 Camera Device Tree Overlay: C3x8"

  • C1-MP

    sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="TIERIV GMSL2 Camera Device Tree Overlay: C1MPx8"

  • C2-MP

    sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="TIERIV GMSL2 Camera Device Tree Overlay: C2MPx8"

Step 4: Restart the System

To apply the device tree changes, power off the system and turn it back on.

sudo shutdown -h now

(After the EAC-5000 has completely shut down, press the power button to start it.)

1.4.6. Verify Camera Recognition#

Open a terminal and run the following command to verify that the cameras are recognized as V4L2 devices. If the number of video devices matches the number of connected cameras, the camera recognition check is complete.

ls /dev/video*
/dev/video0
/dev/video1
.
