3.2.3 Internet Method
Points to be Considered
Internet Method of Firmware Upgrade is applicable for release
9018 / 9019 and beyond.
Internet Method of Firmware upgrade has two parts
o Libre Application Firmware
o GCAST Firmware
Updating LS-Application Firmware (83_IMAGE_network) is
mandatory in internet method of firmware upgrade process.
HOST-MCU firmware can be updated only along with the LS-
Application firmware. Independent update of HOST-MCU firmware
is not allowed.
GCast firmware update takes place automatically whenever there
is any update from Google server. After successful update, LS
module will send reboot command to Host-MCU. It’s up to Host-
MCU to reboot whenever required.
LS9 User Guide
Libre Wireless Technologies User Guide : LS9 / LS9AD, Ver. 5.3 Page 21 of 75
Libre Confidential
For manual update of GCast firmware, customers should get in
touch with Google to get the required OTA package
(application.zip).
Each customer has to maintain their own server; in which they will
place their own customized image.
Server setup Requirements
Minimum Server System Requirements: Intel i5 processor, HDD 80GB, RAM
8GB.
Operating System : Ubuntu server 16.04
Public IP from ISP providers.
Down Time should be ZERO.
Customers can have server setup with above requirements or any cloud service provider
with down time ZERO.
Use only ‘http server’. ‘https server’ is not supported in LS9.
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 <<Link to firmware_download.xml file>>
Firmware Download XML Structure
Firmware Download XML file includes the following tags.
LS9 User Guide
Libre Wireless Technologies User Guide : LS9 / LS9AD, Ver. 5.3 Page 22 of 75
Libre Confidential
fw_version: fw_version is tag used to set the firmware version.
firmware version should start with ‘p’ followed by the actual
version number.
For example, p0902
mcu_version: mcu_version tag is used to set the HOST-MCU
version.
firmware: Firmware tag is used to give the URL of the system
firmware image.
For example, http://192.168.1.143/83_IMAGE_network_9040
otapackage: Ota package is used to give the link of the CAST OTA
package. The CAST OTA package is downloaded, when LS-
Firmware Upgrade is initiated. OTA file can be upgraded only
when a higher Firmware version is available in the server.
For example, http://192.168.1.143/application.zip
If the module is a Non-TZ module, then the otapackage tag should not be
included in the xml file.
Customers can obtain the CAST OTA from Google on signing of the appropriate
agreement with Google.
crc32check: CRC32 Check for firmware image which is mentioned
in <firmware> field.
CRC check is applicable for the Single-Image (LS-Application Image
+ HOST-MCU Image).
CRC check is not applicable for GCast OTA Application Image.
ForceUpgrade: Setting the tag ForceUpgrade as true, is to ensure
the start of firmware upgrade on the device immediately.
Ensure to provide the direct URL link for the URLs of Firmware Download XML,
Firmware, and Cast OTA package. Redirection methods are not supported.

Application will parse the XML and verify the Firmware version of LS9 and host MCU
version. If the given versions in the XML are greater than existing version in DUT,
firmware upload process continues. Otherwise it aborts the upload mechanism. The URL
from the <firmware> tag will be updated on ENV: fwupdate_link.
To update the Application Image on to the LS9 module proceed as below.
Step 1. Update the NV-Item fwdownload_xml with the URL of the XML file.
Step 2. Reboot the device,
internet method of firmware update is triggered, when the device successfully
connects to the network.
Step 3. LS9 will compare the present build version (saved in “cast_version” env
item) with <fw_version> of the XML file, and if the <fw_version> is more than that
of present build version, then only Internet upgrade starts automatically.
Step 4. LS9 sends Message-Box 223 to HOST-MCU, indicating availability of
firmware.
Step 5. Module reboots on successful completion of upgrade process.
