RPI-Board

...

1. Flash the RDKC 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. Open /etc/include.properties file and verify the CLOUDURL parameter where XConf Server URL is configured
4. Verify the image version ( cat /version.txt) displays the flashed image version
5. Open /rdklogs/logs/swupdate.log to verify the communication from RPI board with XConf Server and the download status
6. Verify the tftp download is happening by noticing the change of file size using below command: ls /extblock/tftpimage/imagedwnldls  -sh  (use this command frequently to verify the file size change)
7. Once image download completed, the Rpi board will auto reboot and come up with downloaded image
8.  Verify the version of booted image which shows the downloaded image version

...

• Build the image RDK-C Image.
  
• Ensure 8GB sd-card is available for flashing
• Flash the build image to sd-card
• Setup xconf server ready with rules and download location for RPI device
• Place the upgrading image and checksum file in tftp server
• Boot the flashed image

Note :

1. RPI will go for reboot while booting for the first time, since two more partition needs to be created which requires reboot. Depends on the image present in xconf and RPI, further reboot will happen for upgrade. Please refer to design (High level design approach Firmware Upgrade Support in R-Pi - RDK Camera - 2020 Design - M5 - 2020) for how firmware upgrade works with bank switching

2. SD card should be zero filled formatted before starting the firmware upgrade procedure. DriveWipe software is used for this. Please refer the you-tube video link for the SD card full format process.
