== Introduction ==
This article provides an installation guide for Linux kernel and Debian root file system on the UCM-iMX7 System-on-Module / Computer-on-Module eMMC internal storage device.

== Preparation steps ==
* Obtain a PC workstation with a USB port.
* Download the Linux package for UCM-iMX7 from [http://www.compulab.com/products/computer-on-modules/ucm-imx7-nxp-i-mx-7-ultra-miniature-system-on-module/#devres CompuLab website]. Unzip the package to a directory on your host workstation.
* All image files mentioned below can be found in the {{filename|install}} subdirectory.
* Use the standard microUSB-to-USB cable to connect the host PC to the micro USB connector '''P7''' on SBC-UCM-iMX7).
* Make sure the new {{filename|/dev/ttyUSBx}} device file is created by using the {{cmd|ls /dev/ttyUSB*}} command. {{parameter|x}} is the last number of the ttyUSB device.

=== Preparing installation media ===
* Obtain a micro SD card. Any commercially available micro SD card of 1GB (or larger) may be used.
* Create a first partition on it. The partition can be formatted either ext2/3/4 or FAT file system.
* Copy all files found in the directory {{filename|install}} from the unzipped Linux package to the first partition on the installation media (micro SD card).

== Automatic Installation Procedure ==
* Start terminal emulation software on your PC with the following serial port settings:
<blockquote>
{{:SB-SOM: serial port parameters table}}
</blockquote>
* Plug the installation media (MMC/SD card) to the SD socket (P9) on the SBC-iMX7
* Turn on the UCM-iMX7 evaluation system.
* The system will boot from the SD card and start the automatic installation procedure.

The Automatic Installation Procedure can be terminated by pressing any key during the timeout.
* The installation script performs all required steps including installing Linux images onto the eMMC storage device and setting up the boot environment.
{{Note| The Automatic Installation script cleans up the eMMC device during the installation procedure. All data stored on the eMMC device will be lost.}}

=== Unmount Source /dev/mmcblk0p1 ===
* unmount_source [ ]
Please remove installation SD card
and reboot the board.
</pre>
* Please remember to remove the installation SD card.
* Next, please reboot the board.

== Troubleshooting ==
* Automatic installation doesn't start.
<blockquote>
The U-Boot environment should be set to default:
* Power on the board.
* Press and hold Ctrl-C to get command prompt.
* Set default U-Boot environment and boot the board:
<pre>
UCM-iMX7 # env default -a
UCM-iMX7 # saveenv
UCM-iMX7 # reset
</pre>
</blockquote>
