== Introduction ==
This article provides an introduction on how to install the Debian example root filesystem image on the CompuLab CL-SOM-iMX6UL System-on-Module / Computer-on-Module NAND or eMMC internal storage devices.

== Preparation steps ==
* Obtain a PC workstation with a serial communication port.
* For networked installation you need to install a TFTP server on the host PC. For Windows machines we recommend [http://tftpd32.jounin.net/ TFTPD32] included in the Linux package for CL-SOM-iMX6UL (link below).
* Download the Linux package for CL-SOM-iMX6UL from [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres CompuLab website]. Unzip the package to a directory on your host workstation.
* All image files mentioned below can be found in the {{filename|images}} subdirectory.
* Connect the host PC to the SBC-iMX6UL base-board (connector P8) via the serial cable supplied with the evaluation kit.
* Start the terminal emulation software on your PC. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
* Turn on the CL-SOM-iMX6UL evaluation system. The U-Boot boot-loader will start and you will get a command prompt.
*: {{Note|If the boot settings of your CL-SOM-iMX6UL are different than the default, you may need to press and hold '''Ctrl-C''' while turning the CL-SOM-iMX6UL on, in order to get command prompt.}}

== Boot into the installation environment (ramdisk) ==
The first step in CL-SOM-iMX6UL Linux installation is starting the installation environment (Linux kernel and Ramdisk image).
This can be done using the following media:
* [[#Using installation environment on MMC/SD card|MMC/SD card]]
* [[#Using installation environment on USB storage|USB storage device]]
* [[#Using installation environment from TFTP server|Network TFTP server]]

=== Using installation environment on MMC/SD card ===
* Copy {{filename|kernel.img}}, {{filename|imx6ul-sbc-imx6ul.dtb}}, {{filename|ramdisk.img}} and {{filename|bootscr.img}} from [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Linux package for CL-SOM-iMX6UL] to the root directory on the first partition of the MMC/SD card. The partition can be formatted either ext2/3/4 or FAT file system.
* Insert the MMC/SD card into the SD socket (P6) on the SBC-iMX6UL.
* Use the following U-Boot commands to boot the installation environment on the CL-SOM-iMX6UL configuration:
<pre>
CL-SOM-iMX6UL # mmc dev 0
CL-SOM-iMX6UL # mmc rescan
CL-SOM-iMX6UL # load mmc 0 ${loadaddr} bootscr.img
CL-SOM-iMX6UL # source ${loadaddr}
</pre>
* Continue to the [[#Install Kernel and Debian Linux Images | Install Kernel and Debian Linux Images]] section.

=== Using installation environment on USB storage ===
* Copy {{filename|kernel.img}}, {{filename|imx6ul-sbc-imx6ul.dtb}} and {{filename|ramdisk.img}} from [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Linux package for CL-SOM-iMX6UL] to the root directory on the first partition of the USB storage. The partition can be formatted either ext2/3/4 or FAT file system.
* Insert the USB storage into a USB port on the SBC-iMX6UL.
* Use the following U-Boot commands to boot the installation environment on a CL-SOM-iMX6UL configuration:
<pre>
CL-SOM-iMX6UL # usb start
CL-SOM-iMX6UL # load usb 0 ${loadaddr} bootscr.img
CL-SOM-iMX6UL # source ${loadaddr}
</pre>
* Use the following U-Boot commands to boot the installation environment on a CL-SOM-iMX6UL configuration:
<pre>
CL-SOM-iMX6UL # setenv fdt_file imx6ul-sbc-imx6ul.dtb
CL-SOM-iMX6UL # setenv ramdisk_addr 0x82000000
CL-SOM-iMX6UL # setenv bootargs 'root=/dev/ram0 ramdisk_size=16384 console=ttymxc2,115200'
CL-SOM-iMX6UL # usb start
CL-SOM-iMX6UL # load usb 0 ${load_addr} kernel.img && load usb 0 ${fdt_addr} ${fdt_file} && load usb 0 ${ramdisk_addr} ramdisk.img
CL-SOM-iMX6UL # bootz ${load_addr} ${ramdisk_addr} ${fdt_addr}
</pre>
* Continue to the [[#Install Kernel and Debian Linux Images | Install Kernel and Debian Linux Images]] section.

=== Using installation environment from TFTP server ===
* Connect the CL-SOM-iMX6UL Ethernet port (connector P9 marked as "CM ETHERNET" on the SBC-iMX6UL) to your local network.
* Put {{filename|'''kernel.img'''}}, {{filename|'''imx6ul-sbc-imx6ul.dtb'''}} and {{filename|'''ramdisk.img'''}} from [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Linux package for CL-SOM-iMX6UL] to a location accessible by the TFTP server:
*: - On Windows machine: copy {{filename|'''kernel.img'''}}, {{filename|'''imx6ul-sbc-imx6ul.dtb'''}} and {{filename|'''ramdisk.img'''}} to the same folder and point the TFTP server to that folder
*: - On Linux machine: copy {{filename|'''kernel.img'''}}, {{filename|'''imx6ul-sbc-imx6ul.dtb'''}} and {{filename|'''ramdisk.img'''}} to the TFTP server root directory, usually {{filename|'''/tftpboot'''}} or {{filename|'''/tftproot'''}}.
* You can use U-Boot {{cmd|dhcp}} command to obtain an IP address or manually set {{parameter|ipaddr}} environment variable:
<pre>
CL-SOM-iMX6UL # setenv ipaddr <CL-SOM-iMX6UL ip address>
</pre>
* Set the {{parameter|serverip}} environment variable:
<pre>
CL-SOM-iMX6UL # setenv serverip <tftp server host ip address>
</pre>
* Use the following U-Boot commands to boot Linux on CL-SOM-iMX6UL:
<pre>
CL-SOM-iMX6UL # setenv fdt_file imx6ul-sbc-imx6ul.dtb
CL-SOM-iMX6UL # setenv ramdisk_addr 0x82000000
CL-SOM-iMX6UL # setenv bootargs 'root=/dev/ram0 rw ramdisk_size=16384 console=ttymxc2,115200 ip=dhcp'
CL-SOM-iMX6UL # tftpboot ${load_addr} kernel.img && tftpboot ${fdt_addr} ${fdt_file} && tftpboot ${ramdisk_addr} ramdisk.img
CL-SOM-iMX6UL # bootz ${load_addr} ${ramdisk_addr} ${fdt_addr}
</pre>
* Continue to the [[#Install Kernel and Debian Linux Images | Install Kernel and Debian Linux Images]] section.

== Install Kernel and Yocto Linux Images ==
After the ramdisk image is loaded the Linux login prompt will appear. Login as {{parameter|root}} into the system. Use {{parameter|111111}} password for login:
<pre>
compulab login: root
Password: 111111
</pre>
The next step is installing the kernel and Yocto Linux images. The following media can be used as a source for installation:
* [[#Mount the MMC/SD Card|MMC/SD Card]]
* [[#Mount a USB Storage Device|USB storage device]]
* [[#Mount an NFS drive|NFS drive]]

=== Yocto Image ===

The latest [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Linux package for CL-SOM-iMX6UL] contain a Yocto Linux rootfs image:
* {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}}

=== Mount an MMC/SD Card ===
* Copy the {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}}, {{filename|imx6ul-sbc-imx6ul.dtb}}, {{filename|imx6ul-sbc-imx6ul-wilink.dtb}}, and the {{filename|zImage-cl-som-imx6ul}} from the [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Yocto Linux package for CL-SOM-iMX6UL] to the root directory of any partition on the MMC/SD card. The partition can be formatted as either ext2/3/4 or FAT file system.
* Insert the MMC/SD card into the SD socket (P9) on the SBC-iMX6UL.
* The MMC/SD card is mounted automatically under {{filename|/media/mmcblk0p'''X'''}}. Where '''X''' is the partition number.
* If for some reason the MMC/SD card hasn't been mounted automatically, use the following mount command:
<pre>
root@compulab:~# mkdir -p /media/mmcblk0pX && mount /dev/mmcblk0pX /media/mmcblk0pX
</pre>
* Continue to the [[#Install Images | Install Images]] section.

=== Mount a USB Storage Device ===
* Copy the {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}}, {{filename|imx6ul-sbc-imx6ul.dtb}}, {{filename|imx6ul-sbc-imx6ul-wilink.dtb}}, and the {{filename|zImage-cl-som-imx6ul}} from the [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Yocto Linux package for CL-SOM-iMX6UL] to the root directory of any partition on the USB storage device. The partition can be formatted as either ext2/3/4 or FAT file system.
* Plug the USB storage device to the lower port on the dual USB host connector P6 of the SBC-iMX6UL.
{{Note|SBC-iMX6UL jumper {{parameter|E7}} must be open}}
* The USB device is mounted automatically under {{filename|/media/sd{{parameter|XY}}}}. Where {{parameter|X}} is the device letter and {{parameter|Y}} is the partition number.
* If for some reason the USB storage device hasn't been mounted automatically, use the following mount command:
<pre>
root@compulab:~# mkdir -p /media/sdXY && mount /dev/sdXY /media/sdXY
</pre>
* Continue to the [[#Install Images | Install Images]] section.

=== Mount an NFS drive ===
* Connect the CL-SOM-iMX6UL Ethernet port (connector P21 on the SBC-iMX6UL) to your local network.
* Copy the {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}}, {{filename|imx6ul-sbc-imx6ul.dtb}}, {{filename|imx6ul-sbc-imx6ul-wilink.dtb}}, and the {{filename|zImage-cl-som-imx6ul}} from the [http://compulab.co.il/products/computer-on-modules/cl-som-imx6ul/#devres Linux package for CL-SOM-iMX6UL] to a directory exported through NFS.
* Obtain an IP address for the CL-SOM-iMX6UL:
** Using DHCP:<pre>root@compulab:~# ifup `basename /sys/devices/platform/enet.0/net/eth?`</pre>
** If you do not have a DHCP server, you can set a static IP address using {{cmd|ifconfig}}:<pre>root@compulab:~# ifconfig `basename /sys/devices/platform/enet.0/net/eth?` <ip address></pre>
* Mount the NFS share containing the {{filename|'''zImage-cl-som-imx6ul'''}} and the {{filename|'''fsl-image-gui-cl-som-imx6ul.tar.bz2'''}} files:
<pre>
root@compulab:~# mount -o nolock <host ip>:/path/to/nfs/share /mnt/net
</pre>
* Continue to [[#Install Images | Install Images]] section.

=== Install Images ===
* In this subsection the term {{filename|/mount/point}} can be:
** {{filename|/mnt/net}} if NFS is used
** {{filename|/media/mmcblk0pX}} if an MMC/SD card is used, where X is the partition number.
** {{filename|/media/sdXY}} if USB storage is used, where X is the USB drive letter and Y is the partition number.
Once the ramdisk image is loaded and the media containing the CL-SOM-iMX6UL Kernel and Yocto Linux images is mounted, the installation can be done on:
* [[#Install on the NAND flash|NAND flash]]
* [[#Install on MMC/SD or eMMC|MMC/SD or eMMC]]
==== Install on the NAND flash ====
{{Warning|Required media size is at least '''1G'''. Make sure that the nand device size meets these requirements}}

* In this subsection the term {{filename|/mount/point}} can be:
** {{filename|/mnt/net}} if NFS is used
** {{filename|/media/mmcblk0pX}} if an MMC/SD card is used, where X is the partition number.
** {{filename|/media/sdXY}} if a USB storage is used, where X is the USB drive letter and Y is the partition number.
* Select a correct device tree file that meets the configuration requirements:
:* MMC
:<pre> root@compulab:~# export fdt_file=imx6ul-sbc-imx6ul.dtb
</pre>
:* WiFi
:<pre> root@compulab:~# export fdt_file=imx6ul-sbc-imx6ul-wifi.dtb
</pre>
* Format the NAND flash kernel partition and write the kernel image onto it:
<pre>
root@compulab:~# flash_erase /dev/mtd3 0 0
root@compulab:~# nandwrite -p /dev/mtd3 /mount/point/zImage-cl-som-imx6ul
root@compulab:~# nandwrite -p /dev/mtd3 -s 0x780000 /mount/point/${fdt_file}
</pre>
* Format the NAND flash root filesystem partition:
<pre>
root@compulab:~# ubiformat /dev/mtd4
</pre>
* Attach the NAND flash root filesystem partition:
<pre>
root@compulab:~# ubiattach -m 4 -d 0
</pre>
* Create a ubi volume and name it "rootfs":
<pre>
root@compulab:~# ubimkvol /dev/ubi0 -m -N rootfs
</pre>
* Mount the ubi volume:
<pre>
root@compulab:~# mkdir -p /media/rootfs && mount -t ubifs ubi0:rootfs /media/rootfs
</pre>
* Extract the content of {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}} onto the /media/rootfs:
<pre>
root@compulab:~# tar -xvpjf /mount/point/fsl-image-gui-cl-som-imx6ul.tar.bz2 -C /media/rootfs && sync
</pre>
* Unmount the ubi volume:
<pre>
root@compulab:~# umount /media/rootfs
</pre>
* Continue to the [[#After Installation | After Installation]] section.

==== Install on MMC/SD or eMMC ====
{{Note|The below procedure will work on an empty MMC device only. If you have already used the MMC device, please delete all the partitions before proceeding.}}
* Define an environment variable that describes an MMC/SD device:
'''MMC/SD'''
<pre>
root@compulab:~# export TARGET_DEVICE=mmcblk0
</pre>
'''MMC/SD on a Linux host'''
{{Note|MMC/SD is a removable device. Thus a Linux host can be used in order to deploy the Kernel and the Yocto Linux rootfs on it. In this case it is up to the user to figure out what the MMC/SD card device is. 
For instance it can be '''/dev/sdg'''}}
<pre>
root@compulab:~# export TARGET_DEVICE=sdg
</pre>
'''eMMC'''
<pre>
root@compulab:~# export TARGET_DEVICE=mmcblk1
</pre>
* Clean up the on the '''TARGET_DEVICE''':
<pre>
root@compulab:~# dd if=/dev/zero of=/dev/${TARGET_DEVICE} bs=1M count=1
root@compulab:~# hdparm -z /dev/${TARGET_DEVICE}
</pre>
* Create two partitions for the Linux kernel (FAT32 100M) and root file system (EXT4 the rest of the disk) on the MMC device:
<pre>
root@compulab:~# echo -e "n\np\n1\n\n+100M\na\n1\nt\nc\nn\np\n2\n\n\nw\neof\n" | fdisk /dev/${TARGET_DEVICE}
</pre>
* Adjust the '''TARGET_DEVICE''' name:
<pre>
root@compulab:~# TARGET_DEVICE=$(awk -v device=${TARGET_DEVICE} 'BEGIN {if (device~/mmc/) {part="p"}; print device part}')
</pre>
* Format the first partition with FAT32 file system:
<pre>
root@compulab:~# mkfs.vfat -n boot /dev/${TARGET_DEVICE}1
</pre>
* Format the second partition with EXT4 file system:
<pre>
root@compulab:~# mkfs.ext4 -L rootfs /dev/${TARGET_DEVICE}2
</pre>
* Mount both partitions:
<pre>
root@compulab:~# mkdir -p /media/boot && mount /dev/${TARGET_DEVICE}1 /media/boot
root@compulab:~# mkdir -p /media/rootfs && mount /dev/${TARGET_DEVICE}2 /media/rootfs
</pre>
* Copy {{filename|zImage-cl-som-imx6ul}}, {{filename|imx6ul-sbc-imx6ul.dtb}} and {{filename|imx6ul-sbc-imx6ul-wilink.dtb}} to the first (FAT) partition:
<pre>
root@compulab:~# cp /mount/point/zImage-cl-som-imx6ul /mount/point/imx6ul*.dtb /media/boot && sync
</pre>
* Extract the content of {{filename|fsl-image-gui-cl-som-imx6ul.tar.bz2}} onto the second partition:
<pre>
root@compulab:~# tar --numeric-owner -xvpjf /mount/point/fsl-image-gui-cl-som-imx6ul.tar.bz2 -C /media/rootfs && sync
</pre>
* Unmount both partitions:
<pre>
root@compulab:~# umount /dev/${TARGET_DEVICE}1
root@compulab:~# umount /dev/${TARGET_DEVICE}2
</pre>
* Continue to the [[#After Installation | After Installation]] section.

== After Installation ==
{{Note|If the boot settings of the CL-SOM-iMX6UL are different than default, you may need to press and hold '''Ctrl-C''' while turning the CL-SOM-iMX6UL on, in order to get command prompt.}}

== Boot Environment ==
=== Common Environment Variables ===
<pre>
CL-SOM-iMX6UL # setenv bootdelay 3
CL-SOM-iMX6UL # setenv image zImage-cl-som-imx6ul
</pre>

=== Configuration Dependent Environment Variables ===
CL-SOM-iMX6UL makes use of the same interface for the first MMC and a WiFi.
These devices can't be used simultaneously, thus two different device tree files are provided.
{{Warning|In case that the bootable device is '''mmc 0''', then {{filename|'''imx6ul-sbc-imx6ul.dtb'''}} must be used.}}
* MMC
<pre>
CL-SOM-iMX6UL # setenv fdt_file imx6ul-sbc-imx6ul.dtb
</pre>
* WiFi
<pre>
CL-SOM-iMX6UL # setenv fdt_file imx6ul-sbc-imx6ul-wilink.dtb
</pre>
