Introduction

RDK (Reference Design Kit) is an integrated set of software components, tools and documentation that help in the development of the software stack for set-top box based on the standard Linux operating system which is designed to meet the requirements of the latest generation media servers and clients.

The RDK emulator is an x86 based implementation of the RDK software stack. It is primarily targeted towards the RDK development community (integrators, component developers and application developers) that attempts to simplify the process of working with the RDK software stack without the need for a reference hardware platform.

Purpose of this Document

The purpose of this document is to enable RDK users and developers to be able to bring up the RDK stack and emulator on the PC platform. The document also includes step-by-step procedures to setup & build RDK Emulator

Known Issues

  • eth0/erouter0  interface <ip address> is failing to connect ssh . But, able to connect  ssh with  host using port forwarding in Network settings of Virtual Box.
  • Client is getting the <ip address> from Emulator . But, not in 10.x.x.x 
  • Failed to open webUI configuration .

Overview of RDK Emulator

  • Executes on x86-based platforms including virtualization environments such as Virtual Box and QEMU.
  • Built using Yocto and RDK build frameworks

  • RDK-B Emulator runs RDK-B stack on PC platform, validated through the virtual box based virtualization platform  .

  • Hardware Abstraction Layer supporting Ethernet and Wi-Fi functionalities are introduced to adopt the PC platform.

  • Wi-Fi Hotspot support through external wireless adapter.USB to Ethernet Adapter is used for Ethernet LAN connections.

Bringing up the Emulator on Virtual Box

Host Requirements

RequirementRemarks
Linux                           32/64 bit Ubuntu 16.04 operating system
Free HDD SpaceMinimum 100GB Free Memory
Oracle Virtual Box4.3.18 or higher

Install Virtual Box and follow the following steps to bring up RDK Emulator on Virtual Box:

In the following steps, it is recommended to review the description and screenshot completely before proceeding with steps.

STEP 1: Create your new VM Instance:

  • Open Virtualbox

  • Select New [A popup will come up]

  • Select Type as ‘Linux’

  • Select Version as ‘Other Linux (32 Bit)’

  • Click on “Next”

         


  • Choose a Memory Size of 512 MB

           

  • Use an existing virtual hard drive file which would be your newly built image in *.vmdk format and create your VM:

           

STEP 2: Configure your new VM Instance:

  • Click on “Settings” tab to configure your new VM instance

         

  • Configure your VMs network settings
  • Choose “Bridged Adapter” mode as shown in the screenshot below

       

STEP 3: Run Emulator in Vbox :

  • Boot up your VM by clicking on start
  • Click “start” to launch the Emulator vmdk image
  •  Provide “root” to login Emulator as shown in the screen shot
  •  Emulator usually fetches IP address by default,i.e "ifconfig erouter0"
  •  If not then assign statically using the commands.
  •  For ex: ifconfig eth0/erouter0 192.168.1.49
  •  route add default gw 192.168.1.1 eth0/erouter0
  •  Once IP address for Emulator is up, Emulator shall be accessed in the Host PC using the below command

Once you have the IP address you may SSH into your VM from your linux shell console. Use root as the ssh user.

$ ssh root@<erouter0 ip>
root@qemux86broadband:/# ifconfig

STEP 4: Lanching Emulator in WebUI :

  • In the Host-PC Browser, Enter the eth0/erouter0 IP:8080 to get WebUI
    Ex:http://192.168.1.49:8080
  • WebUI Login Credential's
    Username: admin
    Password: password

Launching WebUI App


  • In the Host-PC Browser, Enter the eth0 /erouter0 IP:8080 to get WebUI
    Ex: http://192.168.1.49:808
  • WebUI Login Credential's
    Username: admin
    Password: password

    Could you share the RDK-B Emulator flash image, I want to study and test it, thanks

    1. Priyankaa K V B

      Hi moon ,

      Link for Emulator build : RDK-B Emulator Dunfell Build Instructions

      We recommend to create a build rather than sharing the image . The ready to use image is available only for Rpi at https://rdkcentral.com/download-instructions/?caller=broadband

      Emulator releases are now not actively made, so dunfell build for emulator should work.

      Please try and let us know if you are facing any issues.

      Regards,
      Priyankaa KVB 

  2. Z-Jack The Ripper

    Why i always get login error "Incorrect password for admin!"     

    I used admin/password 


    (sad) 

  3. sipra samantray

    Hi Z-Jack The Ripper ,


    Could you Reset the admin password first then try again with admin/password ( dmcli eRT setv Device.UserInterface.PasswordReset bool true ).

    1. Z-Jack The Ripper

      Thank you, now it's working 

  4. Z-Arthur Huang

    I follow instructions to build the image and set up VM, but I always get login error "Incorrect password for admin!" even if reset the admin password  

    1. Deepika Ganapathi Bhat

      Hi Z-Arthur Huang

      Once you launch the VM using  Emulator vmdk image, provide “root” to login.
      For WebUi login, "password" is the default password , it should work after Reset also.( dmcli eRT setv Device.UserInterface.PasswordReset bool true)
      if still the issue present , please reset to default factory settings or reboot the vm once and try.

      1. Z-Arthur Huang

        Hi Deepika Ganapathi Bhat 


        It still show "Incorrect password for admin!" for web login after reset( dmcli eRT setv Device.UserInterface.PasswordReset bool true) and reboot.

        1. Deepika Ganapathi Bhat

          Hi Z-Arthur Huang 

          the login issue seen in dunfell build and the issue still needs to be fixed. At present ,the stable release for emulator is available in release branch . Could you please try with  with release branch, Morty version for emulator.

                  Hi Z-Arthur Huang 

                  We verified with platform team .

                  At present ,The Emulator Build is successful only for dunfel release, the webui login and some known issues are present and  still need to be fixed . 

      2. rdkzhang

        Hi Deepika Ganapathi Bhat 

        I always get login error "Incorrect password for admin!".  Where the password exists?

        Reset displays the following error. What should I do?  

        root@qemux86broadband:/# dmcli eRT setv Device.UserInterface.PasswordReset bool true
        CR component name is: eRT.com.cisco.spvtg.ccsp.CR
        subsystem_prefix eRT.
        Can't find destination component.
        root@qemux86broadband:/# 

  5. jianchun zhu

    It seems the login issue seen in dunfell build still exists. 

    I still got the incorrect password after reset.

    Would you please share the method to solve it? 

    When this problem can be solved?

    1. Deepika Ganapathi Bhat

      Hi jianchun zhu 

      It is a known issue which is being fixed .quick fix for this issue is not available at this time.
      however for dunfell release, command line interface we can proceed.
      For webUI,
      The last stable release for emulator is https://wiki.rdkcentral.com/display/CMF/RDK-B_2021q1
      NOTE: With 2021q1 , if you are facing below error , please port https://code.rdkcentral.com/r/c/components/asp/rdk-oe/meta-rdk-bsp-emulator/+/55550/1/recipes-connectivity/obexpushd/obexpushd_0.11.3.bb and check the build
