3. Firmware Update

The Firmware Update process, facilitates update of U-Boot, BSL, and Application images

individually, or all of them together (Single-Image) to the LS-Module.

LSx Platform supports following Sources of Firmware-Image and Interfaces to trigger the

upgrade activity:

 Image Source: USB, SD-Card, Network or Internet  Trigger Interfaces: Shell-Command/Host MCU (via LUCI), Libre App, or

Webpage

For more details on How to trigger Firmware Upgrade via LUCI, refer to

“Light Weight Universal Control Interface Technical Note”

The support for Shell-Command interface to initiate Firmware Upgrade is supported only

from LS5B version vB5004 and onwards.

 For Customers using firmware version vB5004 or before, it is

mandatory to do factory reset by issuing command #SetFacDefault in

the terminal, after upgrading the firmware vB5008 and later.

 Make sure devices with firmware version vB5004 and before is not

present in the same network as that of devices with Firmware version

vB5013 and later.

 While using the latest Libre APP (Android v1p25, iOS v1p3 or later),

released along with firmware version vB5013, Do not use Libre APP that

supports firmware version vB5004 or before.

To know the firmware version and Release date, execute the following command “#getprop”

in the shell:

To update the binary file (Application-Image or Single-Image) on the LS5B module from SD-

Card / USB using the web server proceed as below

Steps

Step 1. Ensure the binary filename as “lsimage” and place the firmware image in

root directory of SD-Card / USB.

The Firmware image should not contain any extension.

Step 2. Insert the SD-Card / USB in the LS5B EVK Step 3. Execute command #netcfg in the device terminal to know the device IP

For Example, 10.0.1.13

Step 4. Enter the IP in the address bar of your browser

Firmware Download XML

NV-Item fwdownload_xml is used to provide the URL for the XML file that contains the

information about Firmware version, HOST-MCU version and the link to download the

firmware. Use the syntax below to provide the URL for firmware update.

To Provide the URL for Firmware Update over Internet

#setenv fwdownload_xml http://10.0.1.14/share/firmware/LS5B/firmware_download.xml

Firmware Download XML Structure

Firmware Download XML file includes the following tags.

 fw_version: fw_version is tag used to set the firmware version. firmware version

should start with ‘pB’ followed by the actual version number.
