Please note that the BSP flashing process is outside our standard support scope. For any inquiries, troubleshooting, or issues related to OS installation, please contact your hardware distributor or Syslogic support directly.

Please refer to the Product Manual on the RML-A4AGX Product Page for instructions on flashing the BSP to your device.

1.6.3. Hardware Connection#

  1. Ensure that the RML-A4AGX is powered off.

  2. Connect the cameras to the RML-A4AGX using the FAKRA coaxial cables.

  3. Ensure that the lock tabs on the FAKRA connectors are properly seated.

Restriction regarding C2 and C3 camera

Currently, two C2 / C3 cameras cannot be connected to single deserializer board.

For example:

  • Port 1 and 2 … NG

  • Port 3 and 4 … NG

  • Port 1 and 3 … OK

  • Port 1 and 5 … OK

1.6.4. Power ON and Login#

Power On

Power on the RML-A4AGX and confirm that the power-on LED illuminates.

Login

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

1.6.5. Camera Driver Installation#

This process should be performed on the RML-A4AGX.

Step 1: Download the Driver

Open a terminal on the RML-A4AGX 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 RML-A4AGX has completely shut down, press the power button to restart it.)

1.6.6. 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
