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, Internet, or Network
Trigger Interfaces: Shell-Command, or Webpage
To know the firmware version and Release date, execute the following command
“#getprop” in the shell:
3.1. Single-Image Update
Single-Image binary file named, “lsimage” is released to customers on Libre Portal. The
“lsimage” contains U-Boot, Factory-ENV, BSL, and Application.
Customers can update the Single-Image via USB / Internet / Network method. USB Method
of update is the fastest method and is recommended.
3.1.1. USB Method
To update the Single-image binary file (File name: lsimage) on the LS5B module from USB
based on a trigger from Command-Shell, proceed as below:
Steps:
Step 1. Ensure the name of binary file as “lsimage” and place the firmware image in
root directory of USB drive.

Step 2. Insert the USB to the LS5B EVK
Step 3. Execute command #fwupgrade in the device terminal (Shell Interface) to
initiate the firmware upgrade from USB
The firmware upgrade process proceeds as below:
The LS5B looks for valid firmware image in USB drive. Once the image is found, firmware
upgrade continues as shown in the image below with indication of the firmware upgrade
progress.

4. Configuring Non-Volatile-Item
The latest LS-Images supports NV-Item from application
only and is accessible from Application Shell prompt. NV-item in
U-Boot is not supported anymore.
To configure all the NV-Item values at one shot as per customer
choice, customers can use the envitem.xml file. This xml file is used
to generate a final Golden-Image for production.
Non-Volatile (NV) item in LibreSync is configured through command line.
To configure the NV-Item, type the below command in the command line and
Reboot the LS-Module.
Syntax of the Command to set NV-Item
#setenv <NV_item_name> <value>
Syntax of the Command to Reboot
#reboot
To know the value of the NV-Item set, type the below command in the command
line.
Syntax of the Command to Know the Value of NV-Item
#getenv <NV_item_name>
To reset all the NV-Items to factory default values, type the below command in

7.1. Libre APP for Android
LUCI enables user to remotely, control the LibreSync LS5B enabled product using the Libre
Application for android. The application can be used to browse DLNA-DMS in the network,
SD Card connected to device and other online radio stations such as vTuner and TuneIn ,
and stream music using the DMP feature supported by LS5B.
For more information on using Libre APP refer
LibreWireless-Usability_Guide_Dynamic_Direct_Multi-Node_Streaming
7.2. DDMS
A Wireless Dynamic Direct Multi-Node Streaming (DDMS) Zone is a group of nodes, (DDMS
enabled speakers) chosen dynamically by an end user to synchronously play audio from a
given content source.
This group of speakers can play music from any Audio Source synchronously without any
delay between the nodes. Each group can consists of two or more nodes.
For information on setting up devices for DDMS, and Using Libre App refer to

7.3. Software Security
LibreSync software is secured using Crypto IC. Crypto IC is embedded either in the LS5B
module or the ACP. Crypto IC authenticates and allows only the valid LS5B software to boot
on the LS5B modules.
7.4. Source Switching
LibreSync enables user to switch the playback sources without any hitches. User can
choose to stream music either from AirPlay or UPnP server and the music streams on the
selected device from the source.
For example, A LS Device streaming AirPlay, starts streaming music from DLNA / DMR
when, the user selects music from Win 7 -Media Player to be played on the device.
7.5. Autosense of Audio CODEC
The new LS Firmware will automatically detect the presence of Audio CODEC in the
firmware.
If LS-SoC detects Wolfson CODEC (WN8904) on LS-I2C bus, then LS-Module takes care of
controlling the Audio CODEC and is applicable to LS5B EVK.
If Wolfson CODEC is not detected, LS-SoC does not control the Audio CODEC. Host MCU
must take care of handling AUDIO DAC / CODEC.
7.6. AUX-In Support
Users can connect Audio Source to AUX-In jack of EVK and select the source from Libre-
APP.
7.7. Airplay®
After the speaker or device is configured to the network, it is discovered by the iOS device
and iTunes, and is available for AirPlay streaming.

To start playback from Apple Device following sequence is to be followed.
Step 1. LS sends the new source to the Host MCU over Message-Box# 10
Step 2. Host MCU may send a command to LS (Command Type: GET) over Message-
Box#50 (Current Source – with value 16 that is Apple Device) to get to know the
current playback source, if any.
Step 3. Host MCU takes a decision whether it has to allow/disallow the new Audio
Source.
Step 4. Send a confirmation on Message-Box#11 with data field set to 1/0 for
Allowed/Not-allowed respectively.
Apple Device Connection Status
When Apple device is connected Message-Box # 38 is updated with the value '2'
When it is disconnected Message-Box # 39 is updated with the value '2'.

15. Design Requirement
Boot strap signals as mentioned in the Table 7-1, should not be driven by external devices
until the module (SoC) comes out of reset.
This mandates implementation of appropriate power sequencing mechanism
on base-board. That is, there has to be 150ms delay between Supplying power
to LS module (SoC) and power to any other device on the base-board.
Table 7-1: Boot Strap Signal Requirement
Typically 150 ms is the time taken to come out of the reset after power on of the module
(SoC).

17.2. Storage Conditions
25. Do not use or store modules in the corrosive atmosphere, especially where
chloride gas, sulfide gas, acid, alkali, salt or the like are contained. Also, avoid
exposure to moisture.
26. Assemble the modules within 6 months. Check the soldering ability in case of
longer than 6 months.
