== Introduction ==
The CM-FX6 firmware consists of two components: Secondary Program Loader (SPL) and U-Boot, both provided on a single binary image {{filename|cm-fx6-firmware}}.
This article describes the firmware update process for CM-FX6 system-on-module product.

== Preliminary setup ==
* Make sure to power off the CM-FX6 evaluation platform.
* Connect the host PC to the SB-FX6 base-board (connector P60) via the serial cable supplied with the evaluation kit.
* Start 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 CM-FX6 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 CM-FX6 are different than default, you may need to press and hold ^C while turning the CM-FX6 on, in order to get command prompt.}}

== Updating Firmware on the SPI flash ==
CM-FX6 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 CM-FX6 DRAM
# Flashing image to the on-board SPI flash

=== Updating from SD card ===
* Copy the firmware binary image {{filename|cm-fx6-firmware}} from [http://compulab.co.il/products/computer-on-modules/cm-fx6/#devres U-Boot package for CM-FX6] to the root directory of the SD card.
* Insert the SD card into the SDIO3(BOOT) socket on SB-FX6.
* Start the U-Boot MMC subsystem:
<pre>
# mmc dev 2
# mmc rescan
</pre>
* Check that the storage device is ready:
<pre>
# fatls mmc 2
</pre>
* Load the firmware binary into the memory:
<pre>
# fatload mmc 2 10800000 cm-fx6-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from USB storage ===
* Copy the firmware binary image {{filename|cm-fx6-firmware}} from [http://compulab.co.il/products/computer-on-modules/cm-fx6/#devres U-Boot package for CM-FX6] to the root directory of the USB storage device.
* Plug the USB storage device into the USB host connector (P13) on SB-FX6.
* Start the U-Boot USB subsystem:
<pre>
# usb start
</pre>
* Check that the storage device is ready:
<pre>
# fatls usb 0
</pre>
* Load the firmware binary into the memory:
<pre>
# fatload usb 0 10800000 cm-fx6-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from TFTP server ===
* Setup a TFTP server
* Put the firmware binary image {{filename|cm-fx6-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>
* Download the SPL binary into the memory:
<pre>
# tftp 10800000 cm-fx6-firmware
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Flashing images ===
* Make U-Boot probe the on-board SPI flash:
<pre>
# sf probe 0
</pre>
* Erase the on-board SPI flash:
<pre>
# sf erase 0 80000
</pre>
* Write the firmware image into the on-board SPI flash:
<pre>
# sf write 10800000 0 80000
</pre>
* Reset the CM-FX6 evaluation platform.
