eMMC Version

Note: the eMMC version will not run the system from the SD card.

1.Install rpiboot

For Windows:

http://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe

For Maca and Linux:

https://github.com/raspberrypi/usbboot#building

2.Push the DIP switch 1 (USB OTG) and 2 (RPI BOOT) to ON to enter BOOT mode.

3.Plug the Type-C into the USB port of the computer (in order to avoid problems caused by the insufficient USB power supply of the computer, it is best to use a USB-Hub with an external power supply, or use an external power supply to power the CM4 via the 5V port of the 40 pin pin header). Run sudo ./rpiboot (Mac/Linux) or rpiboot.exe on Windows, then the eMMC of CM4 will be recognized as a mass storage device by the computer (if rpiboot reports an error at this time, you can try to re-plug the USB).

4.The step of using the Raspberry Pi Imager to write the OS image is exactly the same as the LITE version. Note: the SSH function should also be enabled.

5.When the writing is completed, push the DIP switch 1 (USB OTG) and 2 (RPIBOOT) back to OFF to enter the normal working mode.

Precautions

  • All unplugging and plugging operations should be performed under the condition of power off, including enabling the eMMC writing function.
  • Pay attention to the heat dissipation of CM4. If the running application consumes too many system resources, the CM4 will get hot quite seriously.
  • Handle the board gently to prevent damage.
