== Introduction ==
The CM-T335 Firmware consists of two components: Secondary Program Loader (SPL) and U-Boot.
This article describes the firmware update process for CM-T335 system-on-module product.

== Preliminary setup ==
* Make sure to power off the CM-T335 evaluation platform.
* Connect the host PC to the SB-T335 base-board (connector P11) 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-T335 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-T335 are different than default, you may need to press and hold ^C while turning the CM-T335 on, in order to get command prompt.}}

== Updating Firmware on the micro SD card ==
The firmware can be updated using a workstation with a micro SD card reader, or using CM-T335 module Linux environment.
* To update the SPL, just replace it's binary file ({{filename|MLO}}) on the micro SD card with the desired version.
* To update the U-Boot, just replace the U-Boot binary file ({{filename|u-boot.img}}) on the micro SD card with the desired version.
* Plug the micro SD card into the micro SD card socket of the SB-T335.
* Reset/power on the CM-T335 evaluation system to boot the updated firmware.

== Updating Firmware on the NAND flash ==
CM-T335 firmware can be updated from a micro SD card or using network TFTP download.
Both methods are performed from the U-Boot command line and include following common steps:
# Loading binary images from the selected media to the CM-T335 DRAM
# Flashing images to the on-board NAND flash

=== Updating from micro SD card ===
* Copy the firmware binary images {{filename|MLO}} and {{filename|u-boot.img}} from [http://compulab.co.il/products/computer-on-modules/cm-t335/#devres U-Boot package for CM-T335] to the root directory of the micro SD card.
* Insert the micro SD card into the micro SD socket (P23) on SB-T335.
* Start the U-Boot MMC subsystem:
<pre>
# mmc rescan
</pre>
* Check that the storage device is ready:
<pre>
# fatls mmc 0
</pre>
* Load the SPL binary into memory:
<pre>
# fatload mmc 0 80a00000 mlo
</pre>
* Load the U-Boot binary into memory:
<pre>
# fatload mmc 0 80100000 u-boot.img
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Updating from TFTP server ===
* Setup a TFTP server
* Put the firmware binary images {{filename|MLO}} and {{filename|u-boot.img}} 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>
# setenv serverip <server ip>
</pre>
* Download the SPL binary into memory:
<pre>
# tftp 80a00000 MLO
</pre>
* Download the U-Boot binary into memory:
<pre>
# tftp 80100000 u-boot.img
</pre>
* Proceed to [[#Flashing images|Flashing images]] section

=== Flashing images ===
* Erase the on-board NAND flash for SPL image:
<pre>
# nand erase 0 80000
</pre>
* Write the SPL image into the on-board NAND flash:
<pre>
# nand write 80a00000 0 20000;
</pre>
* Erase the on-board NAND flash for U-Boot image:
<pre>
# nand erase 200000 80000
</pre>
* Write the U-Boot image into the on-board NAND flash:
<pre>
# nand write 80100000 200000 60000;
</pre>
* Remove the micro SD card from the micro SD socket.
* Reset the CM-T335 evaluation platform.
