== Introduction ==
The CL-SOM-iMX7 firmware consists of single U-Boot binary image {{filename|cl-som-imx7-firmware}}.
This article describes the firmware update process for CL-SOM-iMX7 system-on-module product.

== Preliminary setup ==
* Make sure to power off the CL-SOM-iMX7 evaluation platform.
* Connect the host PC to the SBC-iMX7 base-board (connector P8) via the serial cable supplied with the evaluation kit.
* Start terminal emulation software on your PC with the following serial port settings:
<blockquote>
{{:SB-SOM: serial port parameters table}}
</blockquote>
* Turn on the CL-SOM-iMX7 evaluation system. The U-Boot boot-loader will start and a command prompt will be displayed.
*: {{Note|If the boot settings of your CL-SOM-iMX7 are different than the default, you may need to press and hold '''Ctrl-C''' while turning the CL-SOM-iMX7 on, in order to get command prompt.}}

== Updating Firmware on the SPI flash ==
CL-SOM-iMX7 firmware can be updated from an SD card, USB storage, or using network TFTP download.
Both methods are performed from the U-Boot command line and include following common steps:
# Loading binary image from the selected media to the CL-SOM-iMX7 DRAM
# Flashing image to the on-board SPI flash

=== Common preparation steps ===
* Reset the U-Boot environment to default state:
<pre>
CL-SOM-iMX7 # env default -a
</pre>
* Clean up the address space in order to allow the SPI flash burn with a fixed size:
<pre>
CL-SOM-iMX7 # setenv ubootsize 0x80000; mw.b ${loadaddr} 0 ${ubootsize}
</pre>

=== Updating from SD card ===
* Copy the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.co.il/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] to the root directory of the SD card.
* Insert the MMC/SD card into the SD socket (P9) on the SBC-iMX7.
* Start the U-Boot MMC subsystem:
<pre>
CL-SOM-iMX7 # mmc dev 0
CL-SOM-iMX7 # mmc rescan
</pre>
* Check that the storage device is ready:
<pre>
CL-SOM-iMX7 # ls mmc 0
</pre>
* Load the firmware binary into the memory:
<pre>
CL-SOM-iMX7 # load mmc 0 ${loadaddr} cl-som-imx7-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from USB storage ===
* Copy the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.co.il/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] to the root directory of the USB storage device.
* Plug the USB storage to either port on the dual USB host connector P6 of the SBC-iMX7.
* Start the U-Boot USB subsystem:
<pre>
CL-SOM-iMX7 # usb start
</pre>
* Check that the storage device is ready:
<pre>
CL-SOM-iMX7 # ls usb 0
</pre>
* Load the firmware binary into the memory:
<pre>
CL-SOM-iMX7 # load usb 0 ${loadaddr} cl-som-imx7-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from TFTP server ===
* Setup a TFTP server
* Put the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.co.il/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] in the root directory of the TFTP server
* Setup U-Boot networking:
: for dynamic IP configuration:
<pre>
CL-SOM-iMX7 # dhcp
</pre>
: or for static IP configuration:
<pre>
CL-SOM-iMX7 # setenv ipaddr <ip address>
</pre>
* Setup the TFTP server ip address:
<pre>
CL-SOM-iMX7 # setenv serverip <server ip>
</pre>
* Download the firmware binary into the memory:
<pre>
CL-SOM-iMX7 # tftpboot ${loadaddr} cl-som-imx7-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Flashing images ===
* Make U-Boot probe the on-board SPI flash:
<pre>
CL-SOM-iMX7 # sf probe
</pre>
* Erase the on-board SPI flash:
<pre>
CL-SOM-iMX7 # sf erase 0 ${ubootsize}
</pre>
* Write the firmware image into the on-board SPI flash:
<pre>
CL-SOM-iMX7 # sf write ${loadaddr} 0x400 ${ubootsize}
</pre>
* Reset the CL-SOM-iMX7 evaluation platform.
