==Installation onto eMMC ==
===Preparation steps===
* Set-up the CL-SOM-iMX8 eval-kit (SBC-iMX8) as detailed in [[CL-SOM-iMX8: Evaluation Kit: Getting Started|Getting started with CL-SOM-iMX8 Evaluation Kit]]
* SD-card with minimal capacity of 4GB, which will serve as boot medium and root file system.
* PC workstation for creating bootable SD-card.

=== Prepare Installer SD-card ===
* Download [http://www.compulab.com/products/computer-on-modules/cl-som-imx8-nxp-i-mx-8-system-on-module-computer/#devres CL-SOM-iMX8 Android Installation Image].
* Flash the bootable image to the SD-card, issuing on a PC workstation:<pre>unzip -p /path/to/cl-som-imx8_android-o8-installer-4G.img.zip | sudo dd of=/dev/sdX bs=1M</pre>

=== Installer Boot ===
* Insert bootable SD-card into SD-card slot (P13).
* Power on.
* Press and hold SW5 and SW6.
* Release SW5 and then after 3 seconds release SW6.
* Wait for the boot process to complete.

=== Deployment onto eMMC ===
* Open up a terminal window and issue ''cl-o8-deploy''<pre>cl-o8-deploy</pre>
* Select and confirm the destination device ''/dev/mmcblk0''

== Removing Android from eMMC ==
Andorid Oreo 8 comes with a U-Boot that allows booting the Andoid Image only.<br>
In order to let the board boot a Yocto CompuLab Image, a correct U-Boot must be provided.<br>
{{Note|The Android Installer can be used for it. It has all tools installed.}}
=== Restoring stock U-Boot ===
Make use of [https://github.com/compulab-yokneam/meta-compulab-imx8/wiki/05.-How-To-Flash-U-Boot-to-eMMC ''cl-uboot''] in order to restore a stock U-Boot.
* Boot up the board using the ''Android Installer Image''
