• Introduction
    The Firmware upgrade will upgrade higher or lower version of the current image in BPI target with the help of Xconf server and TFTP/HTTP protocol.


  • TFTP Server Setup

    STEP 1:
    Install xinetd and tftpd-hpa application in your local PC to setup tftp server by using below command
    sudo apt-get install xinetd
    sudo apt-get install tftpd-hpa

          STEP 2:
          Create new folder ,for example "tfphome" in your PC home directory to maintain checksum file and upgrading image file.

          

   

         STEP 3:
         Check tftp file is there or not in /etc/xinetd.d/ directory. if it is not there then create tftp file under this /etc/xinetd.d/ direcotry and add below content.  
         

    
File : /etc/xinetd.d/tftp


  • Verify /etc/default/tftpd-hpa file content

vi /etc/default/tftpd-hpa
 

File: /etc/default/tftpd-hpa


STEP 5: Start tftp server and xinetd server using below commands.
sudo service tftpd-hpa restart
sudo /etc/init.d/xinetd restart


  • Procedure for image flashing
    • Have 2 different broadband images and copy to the linux machine
  • Flash a image to the SD card(SD card Minimum size should be 8GB)
         bzip2 -d <image>
         sudo -E bmaptool copy --nobmap <image> /dev/sdb
         Example:
         $ bzip2 -d rdk-generic-broadband-image-raspberrypi-rdk-broadband.wic.bz2
         $ sudo -E bmaptool copy --nobmap rdk-generic-broadband-image-raspberrypi-rdk-broadband.wic /dev/sd

      


  • With another image
    • Create checksum using the below command
      md5sum "<imagefile_name>" > imagefile_name.txt
    • Copy both (image as well as the checksum) to tftp server
      for Ex:
      md5sum "rdkb-generic-broadband-image_rdk-next_20251201131409.bin.wic.bz2" > rdkb-generic-broadband-image_rdk-next_20251201131409.bin.wic.bz2.txt
      cp -r rdkb-generic-broadband-image_rdk-next_20251201131409.bin.wic.bz2  rdkb-generic-broadband-image_rdk-next_20251201131409.bin.wic.bz2.txt  /home/xyz/tftphome     

Xconf Server UI Configurations

  • Create Model
    Flow: Xconf-Server ->Common ->Models
    Give ID and Description to setup Model for your device and save that details in xconf server.

          


  • Create MAC List
    Flow: Xconf-Server->Common->MAC Lists
    After entered MAC Lists page press create button to add your device MAC detail and save the details.

          


  • Create Firmware config
    Flow: Xconf-Server->Firmware->Firmware Configs
    After entered Firmware Configs page press create button to add your device firmware configuration detail.
    Give Description, File name, Version and select your model name and save the details in xconf server.
    Description: <unique Identifier>
    File Name :<Upgrading image name>
    Version: <Upgrading image name>
    Model: <Model name configured under Common Tab>

         


  • Create Firmware Rule
    Flow: Xconf-Server->Firmware->Firmware Rules
    After entered Firmware Rule page press create button to add your device firmware Rule detail.
    Please Select a Template : <MAC_RULE>
    Name : <Name difined during firmware configs creation>
    Type : <MAC_RULE>
    Build Conditions:eStbMac IN_LIST <List-Id> AND model is <Model_Name>
    Firmware Config:<select the same name defined during configs creation>

          


          


  • Edit Download Location Round Robin Filter
    Flow: Xconf-server -> Firmware -> Download Location Filter -> Edit
    After entered Download Location Filter page press Edit button to add your Download Location detail.
    Location (FQDN) : <xconf.rdkcentral.com>
    Location (full HTTP Location) : <https://xconf.rdkcentral.com/xconf/upload/>
    TFTP :< Tftp server IPv4 and IPv6 Address> 

         


        

  • Add TFTP location
    An HTTP location will be returned by default to all devices. To enable tftp(If you have the download location of the firmware as tftp, then only you need to setup this)as download location for a particular set of devices, we need to override it from firmware rules.
    Flow : Xconf-server -> Firmware ->Firmware Rules -> Define Properties -> Create

          


  • A page will be displayed with options to select the template. Select ‘DOWNLOAD_LOCATION_FILTER’ from the list.

           


  • In this 'firmware rule’ page with type 'DOWNLOAD_LOCATION_FILTER', we need to specify the ‘Build Conditions’ and ‘Action’ , The build condition should be same as that we used to set rule actions(which will set rules for our intended devices). In ‘Properties’ option under ‘Action’, add ‘firmwareDownloadProtocol’ as ‘tftp’, ‘firmwareLocation’ as ‘your tftp location IPV4 address’. This property will override the default value set from ‘Download Round Robin location filter’.

           


  • Note: Setting up IPV4 locations via ‘Download Location Round Robin Filter’ is not supported. This can be set only by the property 'firmwareLocation' from the 'Define Properties' firmware rule page.
    Just like we added tftp location and protocol here, we can also override the default value with http as well. For firmwareDownloadProtocol, add 'http' and for the 'firmwareLocation', add http location.
  • Response example for https://{xconf-ip}:{port}/xconf/swu/stb?eStbMac={mac}. Here the 'firmwareLocation' and 'firmwareDownloadProtocol' are overrided at 'Define Properties' firmware rule.
  • The 'ipv6' addresses will be one of the addresses mentioned in the 'Download Filter' page . If you don't want "ipv6FirmwareLocation", then don't setup it in 'Define Properties' or in the 'Download location filter' pages and you will get only "firmwareLocation" in the response.

           


  • Verification of Firmware test page
    Flow : Xconf-server -> Firmware -> Test Page
    Parameters : eStbMac <MAC-Address>

          


  • Client end Configurations and verification (in BPI)
    Verify the CLOUDURL URL in /etc/include.properties File
    CLOUDURL="https://xconf.rdkcentral.com/xconf/swu/stb?eStbMac="
    root@Filogic-GW:~# cat /etc/include.properties

NOTE : Every time need to flash the different images . Because, here they are using the bank switching approach where the images will be stored in the cloud.
So for the next time, when you try to flash the same image to SD card , the firmware upgrade will not happen . The reason is, it will check in the bank (cloud – active and passive banks). If the image is already available in any one of the bank, then it will not go for image upgrade. 

If you want recover previous image, execute the below command and the device will boot up with the passive bank image.

root@Filogic-GW:~# /usr/bin/fwupgrade recover

Direct Firmware Upgrade using dmcli (Quick Testing)

For development, debugging, or quick validation purposes, firmware upgrades can be triggered directly on the device using the dmcli command without relying on the XConf server.

dmcli Commands
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareDownloadProtocol string <PROTOCOL>
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareDownloadURL string <server_IP:Port_num>
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareToDownload string <Image_name>
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareDownloadAndFactoryReset int 1

Example:

Example
# Using HTTP server.
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareDownloadProtocol string HTTP
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareDownloadURL string http://192.168.2.122:8080
dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_FirmwareToDownload string rdkb-generic-broadband-image_rdk-next_20250904115114.bin.wic.bz2

    What model should one select for Banana Pi when creating FW config? BPIR4? RDKB-BPI-TEST?

    When I try to save FW rule I get an error: <FW_rule_name>: model, do(es) not belong to template MAC_RULE
    I created MAC_AND_MODEL template, but I can't select it during rule creation.
    I made MAC_AND_MODEL rule editable and now it can be selected during rule creation.

    ipv6FirmwareLocation in FW rule for properties definition can not be skipped even though it's optional.
    Created separate template that does not include IPv6.
