RDKV 4.0 Firmware Upgrade on RPI - Upcoming

Introduction

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

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. 

Design Approach

       Initially firmware version is validated against the version mentioned in input and further actions are proceeded only if the versions mismatch

       URL and given parameters are validated

       Pkg.tar.gz file from given HTTP server is copied to a file in /tmp

       The tar package is unzipped to find rootfs tarball.

        create new thread to handle rest of the operations.

         rootfs tar ball is copied to passive memory bank
