4.3.2 CM4 eMMC Version(Note: eMMC version will not tun the system from the
Micro SD card.)
1. Install rpiboot
For Windows:
http://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe
For Mac and Linux:
https://github.com/raspberrypi/usbboot#building
2. Push the DIP switch 4 (USB OTG) and 3 (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 an
external 24V power supply to power the motherboard). 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 4 (USB OTG) and 3 (BOOT)
back to OFF after power off, and power on again to enter the normal working
mode.
