🛠 Getting Started with the Smart Display Module on Compute Module 5

Objectifs

This tutorial guides advanced users through the physical installation and initial software configuration of the Raspberry Pi Smart Display Module (SDM). The goal is to validate cable-free communication between the Compute Module 5 (CM5) and a professional SDM-compatible display, ensuring power delivery, 4K video transmission, and stability for 24/7 continuous operation.

Matériel nécessaire

• A Raspberry Pi Compute Module 5 (CM5) with sufficient RAM.
• The Raspberry Pi Smart Display Module (SDM adapter).
• A professional Intel SDM-compatible display (verify compatibility with Sharp Display Solutions Europe).
• A power supply compliant with CM5 and SDM specifications.
• A computer for preparing the SD card or eMMC.
• A set of Torx or Allen keys depending on the display chassis.

Étapes

1. Software Preparation: Install Raspberry Pi OS (64-bit version) on the CM5 storage. Ensure graphics drivers are up to date to support 4K output via the SDM interface.
2. CM5 Insertion: Gently insert the Compute Module 5 into the Smart Display Module connector. Verify pin alignment to avoid hardware damage.
3. Display Installation: Slide the SDM-CM5 assembly into the SDM port of the professional display. The locking mechanism must click firmly into place. This step establishes power, data, and control connections without external cables.
4. M.2 Configuration (Optional): If using NVMe storage or an AI accelerator (e.g., Hailo), insert it into the SDM's M.2 slot before final insertion.
5. Boot: Power on the display. The system should boot automatically. Check for the graphical interface on the connected screen.

Vérification

• The display shows the Raspberry Pi OS desktop in native 4K resolution.
• No fans are audible (silent operation).
• In the terminal, run vcgencmd measure_temp to ensure temperature remains stable under load.
• Verify M.2 device detection via lsblk or lspci.
