4.3. Connecting to Host Board

Use the provided FPC cable to connect the camera board to your Nvidia Jetson or Raspberry Pi Compute Module.

1. Ensure the host board is powered off.
2. Gently open the FPC connector latch on both the camera board and the host board.
3. Insert the FPC cable with the metallic contacts facing the correct direction (usually towards the PCB).
4. Close the latches to secure the cable.

4.4. Instalace ovladače

The camera requires specific kernel drivers to function. Driver installation is crucial and platform-dependent.

• Jetson Boards: This camera relies on kernel drivers. One kernel version typically requires a matching camera driver. Versions older than JetPack 4.3 (L4T 32.3.1) are not supported.
• If you upgrade or downgrade your operating system, which often involves a kernel update, you will need to reinstall a compatible driver.
• For future JetPack/kernel updates, new drivers may be required. Arducam typically provides these updates.
• Refer to the official Arducam documentation or support resources for the latest driver installation guides specific to your Jetson or Raspberry Pi Compute Module version.

5. Návod k obsluze

Once the camera board is physically connected and the drivers are correctly installed, you can begin using it with your host platform.

• Platforma Jetson: Utilize the NVIDIA Argus Camera plugin. This allows for functionalities such as H264 video encoding and JPEG still image capture.
• Ovládání fotoaparátu: The Argus plugin provides control over various camera parameters, including gain, exposure, framerate, and group hold. Consult NVIDIA's Argus documentation for detailed API usage.
• Nastavení objektivu: If using a manual lens, adjust the focus and aperture as needed for your application.

6. Řešení problémů

If you encounter issues with your Arducam IMX477 HQ Camera Board, consider the following troubleshooting steps:

• Kamera nebyla detekována:
  • Verify the FPC cable connection is secure and correctly oriented on both the camera and host board.
  • Ensure the correct kernel driver is installed for your specific JetPack/OS version. Driver mismatches are a common cause of detection failures.
  • Check if your Jetson Developer Kit requires specific hardware modifications (e.g., resistor changes for some Xavier NX dev kits) as documented by Arducam support for certain configurations.
• Špatná kvalita obrazu:
  • Adjust lens focus and aperture.
  • Zkontrolujte světelné podmínky.
  • Review camera settings (gain, exposure, white balance) through the Argus API or other control software.
• Specific Resolution/Framerate Issues:
  • Some Jetson models may have limitations on certain resolutions and framerates (e.g., 1920x1080@60fps might not work on all models, while 4032x3040@30fps might). Consult Arducam support or community forums for known compatibility issues.
• Driver Compilation Errors:
  • If you are compiling drivers from source, ensure all dependencies are met and follow the instructions precisely. Kernel updates often necessitate recompilation.

If problems persist, refer to the Arducam support website or contact their technical support for assistance.
