Introduction

Briefly describe in general terms the system/application and the purpose for which it is intended, written in non-technical terminology. Consider including a high-level architecture diagram for the system. The description should include, but is not limited to, the following:

• Key features or major functions/use cases performed by the system/application
• Architecture of the system in non-technical terms (e.g., client server, Web-based, etc.)
• System environment or special conditions

Raspberry Pi: 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. 

Environment Environment Setup for Emulator and Raspberry Pi

...

$ source meta-cmf-raspberrypi/setup-environment (Select option raspberrypi-rdk-broadband.conf).

Next, you would need to initiate the build using the following command:

...

-             ${HOME}/RaspberryPi/build-raspberrypi-rdk-broadband/tmp/deploy/images/raspberrypi-rdk-broadbandbroadband/rdk-generic-broadband-image-raspberrypi-rdk-broadband.rpi-sdimg

Example:

../build-raspberrypi-rdk-broadband/tmp/deploy/images/raspberrypi-rdk-broadband/rdkb-generic-broadband-image_default_20200206062343.rootfs.rpi-sdimg

Troubleshooting

Error Messages during bitbake for Emulator and solutions.
