  1. Don’t power up yet.
  2. Download and install the required drivers on your PC (if not already done).
  3. Set jumper to prevent boot from emmc.

    Use jumper J2 by setting it to the disable eMMC boot position to prevent the IO board from booting.

  7. Run the RPiboot.exe on your PC. Installed in step 2 along with the drivers.
    The eMMC should now appear in Windows like a USB stick.
  8. Open the emteria installer and choose a Raspberry Pi 4 release (>11.0.13) of your choice.

    Read the tutorial for the installer.

  9. Remove the jumper set in step 3 and the micro USB cable from step 4.

  10. Power up your device and enjoy emteria.OS.

 

Note: To enable ABD over USB for the micro USB port, do the following:
Remove dtoverlay=dwc2,dr_mode=host from the config.txt file. Note that this will disable the standard USB ports.

The Raspberry Compute Module 3 has a lite edition without eMMC storage. Therefore, for these boards the RPiBoot will not be needed. The lite editions support booting from an SD card. You can flash emteria.OS onto the SD card, insert it into the IO board and run the OS on your device.
