== Introduction ==
The CL-SOM-AM57x firmware consists of two components: Secondary Program Loader (SPL) and U-Boot, provided as binary images: {{filename|MLO}} and {{filename|u-boot.img}}.
This article describes the firmware update process for CL-SOM-AM57x system-on-module product.

== Preliminary setup ==
* Make sure to power off the CL-SOM-AM57x evaluation platform.
* Connect the host PC to the SB-SOM base-board (connector P8) via the serial cable supplied with the evaluation kit.
* On your computer, start a terminal emulation program (such as HyperTerminal) with the following serial port settings:
<blockquote>
{{:SB-SOM: serial port parameters table}}
</blockquote>
* Turn on the CL-SOM-AM57x evaluation system. The U-Boot boot-loader will start and you will get a command prompt in the terminal window.
{{Note|If the boot settings of your CL-SOM-AM57x are different than default, you may need to press and hold ^C while turning the CL-SOM-AM57x on, in order to get command prompt.}}

== Updating Firmware on the internal SPI flash ==
CL-SOM-AM57x firmware can be updated from an SD card, USB storage, or using network TFTP download.
All methods are performed from the U-Boot command line and include following common steps:
# Loading binary images from the selected media to the CL-SOM-AM57x SDRAM
# Flashing images to the on-board SPI flash

=== Updating from TFTP server ===
* Setup a TFTP server
* Put the firmware binary image {{filename|cl-som-am57x-firmware}} in the root directory of the TFTP server
* Setup U-Boot networking:
: for dynamic IP configuration:
<pre>
# dhcp
</pre>
: or for static IP configuration:
<pre>
# setenv ipaddr <ip address>
</pre>
* Setup the TFTP server ip address:
<pre>
# setenv serverip <server ip>
</pre>
* Load the SPL and U-Boot binaries into the memory:
<pre>
# tftp 82000000 cl-som-am57x-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from SD Card / USB storage / mSATA drive ===

Copy the firmware binary image {{filename|cl-som-am57x-firmware}} from [https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/#devres U-Boot package for CL-SOM-AM57x] to the root directory of the respective media.

==== Updating from SD card ====

* Insert the SD card into the P9 socket on SB-SOM.
* Start the U-Boot MMC subsystem:
<pre>
# mmc dev 0
# mmc rescan
</pre>

* Check that the storage device is ready:
<pre>
# ls mmc 0
</pre>
* Load the firmware binaries into the memory:
<pre>
# load mmc 0 82000000 cl-som-am57x-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

==== Updating from USB storage ====
* Plug the USB storage device into the USB host connector (P3) on SB-SOM.
* Start the U-Boot USB subsystem:
<pre>
# usb reset
</pre>
* Check that the storage device is ready:
<pre>
# ls usb 0
</pre>
* Load the firmware binaries into the memory:
<pre>
# load usb 0 82000000 cl-som-am57x-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Flashing images ===
* Probe the SPI flash:
<pre>
# sf probe
</pre>

* Write the firmware image into the on-board SPI flash:
<pre>
sf update 82000000 0 C0000
</pre>

* Reset the CL-SOM-AM57x evaluation platform.
