Introduction

The Raspberry Pi 3 Model B+ featuring a 64-bit quad core processor running at 1.4 Ghz. R-Pi3 B+ supports the dual band 2.4GHz and 5GHz IEEE 802.11.b/g/n/ac wireless LAN which provides an high edge for the broadband developer community to test the RDK-B stack with Router, WiFi functionalities. 

Build Instructions

Repo setup

In order to install Repo make sure you have a /bin directory in your home directory and that it is included in your path

Repo Setup Steps
$ mkdir ~/bin
$ PATH=~/bin:$PATH
Download the repo tool and ensure that it is executable
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Note: it is also recommended to put credentials in .netrc when interacting with repo.

A sample .netrc file is illustrated below


.netrc
machine code.rdkcentral.com
login YOUR_USERNAME
password YOUR_PASSWORD

Yocto Build Steps

To build, follow below instructions

Build Steps
$ mkdir <workspace dir>
$ cd <workspace dir>
$ repo init -u https://code.rdkcentral.com/r/manifests -b rdk-next -m rdkb-extsrc.xml
$ repo sync -j4 --no-clone-bundle
$ source meta-cmf-raspberrypi/setup-environment (Select option raspberrypi-rdk-broadband.conf)
$ bitbake rdk-generic-broadband-image


Hardware and Setup Information


Note : RPI-3 B and B+ have same Build instructions and testing procedure

Flashing Procedure

Following command can be used to flash the RPI image to sd card using linux machine . dd tool should be available in linux

Flash command
sudo dd if=<path to ImageName.rpi-sdimg> of=<path to SD card space> bs=4M
Example:
$ sudo dd if=rdk-generic-broadband-image-raspberrypi-rdk-broadband.rpi-sdimg of=/dev/sdb bs=4M

https://www.balena.io/etcher/ can be used to flash RPI image in sd card using windows 

RDK-B Bootup Sequence 

RDKB Boot sequence for Router Profile


  • GwProvApp-Ethwan is the entry point for RDK-B stack middleware. It does all gateway initialization as above
  • Responsible to initiate the registration of all services on boot -up. Responsible for all provisioning of LAN,FIREWALL(iptables),BRIDGE,etc
  • GwProvApp-EthWan is specifically designed for Ethernet only Input feed for WAN Network Connection(i,e erouter0)

Router Functionality Use Case - Internet connectivity for Wired and Wireless Client(s)

  1. Ethernet Port of RPI should be connected to WAN Network
  2. Connect WiFi Dongle to RPI ( Please refer to supported dongle here RDKB RPI Setup Information#DonglesInformationLinks )
  3. Client PC(s)  should be connected to RPI through Usb2Ethernet Adaptor which should be supported by RPI ( Please refer to https://elinux.org/RPi_USB_Ethernet_adapters for supported usb to ethernet adapter by RPI ). Ethernet switch is an optional in between usb2ethernet adapter and Client PC
  4. Once powered on, RPI should be able to list interfaces erouter0,brlan0 and wlan0 after boot up 
  5. Logs can be verified under /rdklogs/logs folder 
  6. Now, client pc should be able to get private ip in the rage 10.0.0.x range 
  7. Client PC should be able to connect to internet now. Ping test can also be done by connecting gateway ip 10.0.0.1
  8. Connected client PC information can be verified through webui by executing URL 10.0.0.1 in Client PC Browser and login with following credentials 
    1. Username : admin
    2. Password : password
  9. Two radios are supported by RPI (2.4 and 5 GHz) respectively. By default following SSID's are broadcasted by RPI under respective radio 
    1. 2.4GHz (Private WiFi)
      1. SSID name - "RPI3_RDKB-AP0" 
      2. Password - "rdk@1234"
    2. 5 GHz (Xfinity WiFi)
      1. SSID name - "RPI3_RDKB-AP1" 
      2. Password - "rdk@1234"
  10. Connect mobile with above default SSID name and password for respective radio. Any one radio should be used for establishing connection in mobile
  11. Now, mobile should be able to get private ip in the rage 10.0.0.x range 
  12. To get Internet for mobile, user should configure captive portal by accessing any url or 10.0.0.1 from mobile browser. When RPI image is flashed for the first time captive portal will be enabled which will auto redirect to captive portal page and asks user to re-configure the default SSID name and password of radio(s) . Please refer to Captive Portal in R-Pi User Manual for more information. 
  13. After reconfiguration of SSID username and password in webUI, provide the modified SSID and password in mobile too for reconnection with RPI
  14. Now, mobile should be able to browse the internet. Please refer to Clients Connection and its set up Diagram in RPI - User Manual for more information regarding the same for both wired and wireless connection information
  15. Please refer to link Webui Functions for various features that can be controlled through webui
