RPi - Board

1. Flash the RDKB image supported for Firmware upgrade feature in the Rpi and verify the 2 partitions(ex. mmcblk0p1, mmcblk0p2) present under dev folder (use command ls /dev)
2. Device auto-reboots and verify there are 2 more additional partitions are created (ex. mmcblk0p3, mmcblk0p4).
3. Verify the image version ( cat /version.txt) displays the flashed image version
4. Verify FwUpgradeManagerLog.txt file is generated in /rdklogs/logs directory.
   
5. Verify the http download is happening by noticing the change of file size using below command : cd /firmware/imagedwld ls -lh(use this command frequently to verify the file size change)
   
6. Once image download completed, the Rpi board will auto reboot and come up with downloaded image
7.  Verify the version of booted image which shows the downloaded image version
