3. Nastavení

Follow these steps to set up your Compute Module 4 IO Board:

1. Install Compute Module 4: Carefully align your Compute Module 4 with the CM4 socket on the IO Board and press it firmly into place. Ensure it is seated correctly.
2. Insert SD Card (CM4 Lite only): If you are using a Compute Module 4 Lite (without eMMC), insert a microSD card with a pre-installed operating system into the dedicated SD card slot.
3. Připojení periferií:
   • Zobrazit: Connect your display(s) to the HDMI ports or MIPI DSI connectors.
   • Fotoaparát: Connect MIPI CSI-2 cameras to the camera interfaces.
   • Zařízení USB: Plug in your keyboard, mouse, or other USB devices into the USB 2.0 ports.
   • Síť: Pro přístup k síti připojte ethernetový kabel k portu Gigabit Ethernet.
   • Ventilátor: If using an external fan, connect it to the fan header.
   • Zařízení PCIe: If applicable, install your PCIe expansion card into the PCIe Gen 2 x1 socket.
4. Připojení napájení: Connect a 12V / 5V DC power supply to the DC power input jack. Ensure the power supply meets the board's requirements.
5. Konfigurace propojky: Depending on your specific use case, you may need to configure jumpers. For example, to disable eMMC boot or wireless functionality. Refer to the official Raspberry Pi documentation for detailed jumper settings.

4. Návod k obsluze

Once the board is set up, you can begin operating your Compute Module 4 IO Board:

• Zapnutí: Apply power to the board. The CM4 should boot up according to the installed operating system.
• Operační systém: The Compute Module 4 requires an operating system, typically Raspberry Pi OS. For CM4 Lite, this is installed on the microSD card. For CM4 with eMMC, the OS is flashed directly to the eMMC storage. Refer to the official Raspberry Pi documentation for OS installation and flashing procedures.
• Použití rozhraní:
  • HDMI: Use standard HDMI cables to connect to monitors.
  • USB: Standard USB devices will function as expected.
  • Ethernet: Provides wired network connectivity.
  • CSI/DSI: These interfaces are for specific camera and display modules, requiring appropriate drivers and software configuration.
  • PCIe: Ensure compatible drivers are installed for any PCIe expansion cards.
• Hodiny reálného času: The onboard RTC can be configured to keep accurate time, even when the board is powered off, provided a battery is installed in the RTC socket.

5. Údržba

Proper maintenance ensures the longevity and reliable operation of your Compute Module 4 IO Board:

• Podmínky prostředí: Operate the board in a clean, dry environment, away from extreme temperatures, humidity, and direct sunlight.
• Čištění: Use a soft, dry brush or compressed air to remove dust from the board. Avoid using liquids or abrasive cleaners.
• Statický výboj: Always handle the board by its edges and take precautions against electrostatic discharge (ESD) to prevent damage to sensitive components.
• Aktualizace firmwaru a softwaru: Regularly update the operating system and any installed software to ensure optimal performance and security. Refer to official Raspberry Pi documentation for update procedures.
• Napájení: Use only a compatible and stable power supply to prevent damage.

6. Řešení problémů

If you encounter issues with your Compute Module 4 IO Board, consider the following troubleshooting steps:

• Žádné napájení/žádné spuštění:
  • Ověřte, zda je zdroj napájení správně připojen a zda poskytuje správné napětí.tage (12V / 5V).
  • Ensure the Compute Module 4 is properly seated in its socket.
  • If using CM4 Lite, check if the microSD card is inserted correctly and contains a valid OS image.
  • Check jumper settings, especially those related to eMMC boot.
• Žádný výstup na displej:
