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

• Use Gparted tool for resizing and partition creation by using the following link
  • Partioning and Resizing using GParted GUI

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 

•     Create mount directory and execute mount  for the partition 4 

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

In above command, storage partition 4 will get mounted to videomnt directory

• Copy the RDK-Video image which is present in the extblock

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. Copy the bank_broadband_switch.sh file to partition 4 as below

sudo cp bank_broadband_switch.sh videomnt/lib/rdk/

8. Unmount videomnt directory as below

sudo umount videomnt

Multiboot Scripts for switching

9. Now copy broadband multi boot change scripts to broadband image as below

     Place the script files rpi_sw_install1.sh rpi_sw_install.sh swupdate_utility.sh bank_image_switch.sh bank_video_switch.sh imageFlasher.sh in /lib/rdk path of broadband image by following the below scripts

#For ex. 
mkdir -p bbmnt
sudo mount /dev/sdb4 bbmnt

#In above command, storage partition 2 will get mounted to bbmnt directory

# Now copy the broad band change scripts from host to broadband image rootfs in partition2 (/dev/sdb2) mounted to bbmnt as below

sudo cp rpi_sw_install1.sh rpi_sw_install.sh swupdate_utility.sh bank_image_switch.sh bank_video_switch.sh imageFlasher.sh bbmnt/lib/rdk/

# Now unmount the bbmnt

sudo umount bbmnt

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

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

       ssh root@<RPI-Board IP>

Switching to RDK-Video Image from RDK-Broadband 

12. 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

13.  R-Pi should boot up with video image

14. Now this image can be switch back to broadband image by executing following script

sh /lib/rdk/bank_broadband_switch.sh

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.
