Important Notes
-
microSD Card Support: If you are using a CM5 module with onboard eMMC storage, the microSD card slot cannot be used. The microSD slot is only available when using a CM5 Lite module.
Note: The SSD disk is also not supported with the eMMC version. -
Programming the CM5 via USB‑C: To access the CM5 eMMC or microSD storage through USB‑C:
- Connect the Pi5R16 to your computer using a USB‑C cable.
- Run the Raspberry Pi
rpibootutility on your computer. - The eMMC or microSD storage will appear as a removable drive.
- Flash Raspberry Pi OS or other Linux distributions directly.
