4. Setup Guide
4.1 Heatsink Installation
Proper heat management is crucial for the CM5's performance and longevity. The included heatsink helps dissipate heat from the processor.
- Carefully align the heatsink with the processor on the CM5 module.
- Secure the heatsink using the provided screws and risers. Ensure a firm but not overly tight fit to avoid damaging the board.
Note: Ensure the heatsink makes good contact with the processor. Incorrect installation can lead to overheating and performance throttling.
4.2 Antenna Connection
For wireless functionality, connect the external antenna.
- Locate the antenna connector on the CM5 module.
- Gently screw the antenna into the connector until it is finger-tight. Do not overtighten.
4.3 Connecting to a Carrier Board
The CM5 is designed to be integrated into a carrier board. Ensure your carrier board is compatible with the Compute Module 4 form factor, as the CM5 uses B to B connectors.
- Align the CM5 module with the SODIMM-style connectors on your carrier board.
- Gently press down on both sides of the module until it is fully seated in the connectors.
- Secure the module to the carrier board using any provided mounting hardware.
4.4 Operating System Installation
Your CM5104032 module comes with 32GB eMMC Flash storage, which acts as the primary storage for the operating system. Raspberry Pi OS is the recommended operating system.
- Connect your carrier board (with the CM5 installed) to a host computer via USB for initial flashing, if supported by your carrier board.
- Download the Raspberry Pi Imager tool from the official Raspberry Pi website.
- Use the Raspberry Pi Imager to select the appropriate Raspberry Pi OS image and flash it to the CM5's eMMC storage. Follow the on-screen instructions provided by the imager.
- After flashing, safely eject the device from your host computer.
Important: Unlike CM4, CM5 does not have a dedicated 'reboot' button for OS installation. The process relies on the carrier board's capabilities and the Raspberry Pi Imager tool. Ensure your carrier board supports eMMC flashing for CM5.
5. Operating Instructions
5.1 Initial Power-Up
Once the CM5 is securely installed on a carrier board and the OS is flashed:
- Connect necessary peripherals (display, keyboard, mouse) to your carrier board.
- Apply power to the carrier board. The CM5 should boot up.
- Follow the initial setup wizard for Raspberry Pi OS, which may include setting up Wi-Fi, language, and user accounts.
5.2 Network Connectivity
- Wi-Fi: Configure Wi-Fi settings through the Raspberry Pi OS desktop environment or command line. Ensure your external antenna is connected for optimal performance.
- Ethernet: Connect an Ethernet cable to the Gigabit Ethernet port on your carrier board for wired network access.
5.3 Using PCIe
The onboard PCIe Gen 2 x1 interface allows for expansion with compatible PCIe devices. Refer to your carrier board's documentation for specific instructions on utilizing the PCIe slot.
6. Maintenance
To ensure optimal performance and longevity of your Waveshare CM5 module:
- Keep it Clean: Regularly clean the module and carrier board to prevent dust buildup, which can hinder cooling. Use compressed air or a soft brush.
- Temperature Management: Ensure adequate airflow around the module, especially when operating under heavy loads. The heatsink is crucial for thermal management. Avoid operating in environments exceeding the specified operating temperature range (-20°C to 85°C).
- Software Updates: Keep your Raspberry Pi OS and firmware updated to benefit from performance improvements, bug fixes, and security patches.
- Power Supply: Use a stable and appropriate power supply for your carrier board to prevent power-related issues.
7. Troubleshooting
This section addresses common issues you might encounter.
7.1 Module Not Booting
- Power: Verify that the carrier board is receiving adequate power and that the power supply is correctly connected.
- Seating: Ensure the CM5 module is correctly and fully seated in the carrier board's connectors.
- OS Image: Confirm that the Raspberry Pi OS image was successfully flashed to the eMMC. Try re-flashing if unsure.
- Carrier Board: Check your carrier board's documentation for specific boot requirements or jumpers.
7.2 Wi-Fi/Bluetooth Issues
- Antenna: Ensure the external antenna is securely connected.
- Software: Verify that Wi-Fi and Bluetooth drivers are installed and enabled in Raspberry Pi OS.
- Region Settings: Incorrect region settings can affect wireless performance. Ensure your country is correctly configured in Raspberry Pi OS.
7.3 Overheating
- Heatsink: Check that the heatsink is properly installed and making good contact with the processor.
- Airflow: Ensure the module has sufficient ventilation. Consider adding a fan to your carrier board if operating in high-temperature environments or under continuous heavy load.
- Thermal Paste/Pads: Verify that thermal interface material (if used) is correctly applied between the processor and heatsink.
7.4 Keyboard Layout Issues
If you experience unexpected character input (e.g., '@' instead of '|'), it might be due to an incorrect keyboard layout.
- Configure Keyboard: In Raspberry Pi OS, navigate to Preferences > Raspberry Pi Configuration > Localisation > Set Keyboard and select the correct layout (e.g., 'US' for a US keyboard).
