This page is dedicated for switching the images (broadband to video) specifically for techsummit-2019

RDK- Broadband Image Flashing in SDcard Steps

1. Flash the Broadband image in SD card

sudo dd if=<RPIimage-sdimg> of=</dev/sdc> bs=4M

Example: sudo dd if=rdk-generic-hybrid-refapp-thunder-image_default_20190829072513.rootfs.rpi-sdimg of=/dev/sdc bs=4M


2. Resizing and partition creation

RDK- Video Image Copying in SDcard Steps


3.  Keep RDK-Video image in the host machine
4. Extracting the RDK-Video image into the extblock directory


sudo sh extract.sh <video-image file>
For ex. sudo sh extract.sh rdk-generic-hybrid-refapp-thunder-image_default_20190924125426.rootfs.rpi-sdimg

After executing the above script, Linux kernel and RootFS of RDK-Video image would be present in the extblock directory


5. To Copy the RDK-Video image in  Partition-P4 

For ex. 
mkdir videomnt
sudo mount /dev/sdb4 videomnt

In above command, storage partition 4 will get mounted to videomnt directory
sudo cp -r extblock/v* videomnt/


6. Copy the vrootfs backup data into partition 4  storage bank, to ensure it will acts as video bank as well 

sudo cp -r extblock/vrootfs_backup_data/* videomnt/


7. Unmount videomnt directory as below

sudo umount videomnt


Switching to RDK-Video Image from RDK-Broadband 


8. Now Boot up the SD card in RPI-> it should come up with BB image in partition (P2)


9.  Log into the R-Pi from Host PC execute the below command

       ssh root@<RPI-Board IP>


10. To load the video image which is present in the storage execute the script bank_video_switch.sh

root@RaspberryPi-Gateway:/lib/rdk# sh bank_video_switch.sh


11.  R-Pi should boot up with video image


NOTE:

Ensure that while mounting the SD card in host machine it may have different device names like /dev/sdc * and /dev/sdd * .  Please check host machine accordingly while using device name.
