RDKV 4.0 Firmware Upgrade on RPI - Upcoming

Introduction

 This document covers the design of FirmwareControl plugin  for RPI board. 

Design Considerations

• Decision Overview

• 

Design Limitation

    If the SD card partition is not more than two, new partitions will be created to save image.  This will result in reboot. 

    For the first time, board will reboot twice during firmware upgrade.

• Other Considerations (DAR)

<Alternative designs considered and why one was chosen>

Architecture

• Layout

           <Architecture Diagram>

• Communication

          <Describe the communication between the sub-systems. (Diagrams may be used to illustrate communications). >

External Interfaces (Input/Output files or data sets)

< Identify input interfaces, function call protocol, and the nature of the data structures passed across the interface between the sub-modules>

< Identify output interfaces, function call protocol, and the nature of the data structures passed across the interface. >

Data Model

<Provide a description of the data model>

Limitations

        1. RPI box will reboot after booted for first time which will create more partition, if the  partition table is not more than two. 

Future Enhancements

 1.  Triggering firmwareUpgrade automatically without user intervention.
