Build procedure to generate R-Pi image with Firmware upgrade

The build procedures procedure for broadband are as follows:

1. repo init -u https://code.rdkcentral.com/r/manifests -b rdk-next -m rdkb-extsrc.xml
2. repo sync -j4 --no-clone-bundle
3. source meta-cmf-raspberrypi/setup-environment (Select option raspberrypi-rdk-broadband.conf)
4. bitbake rdk-generic-broadband-imageimage 
   

Flashing the image

Command to flash the image

Generated image has to be flashed to an SD card using this command in local PC:

...

The Raspberry Pi board is connected to the PC via a USB to serial converter and the logs can be checked in console or can be connected via HDMI cable to a TV and logs will be shown in the terminal

Creating checksum file

It is necessary to flash the stable image during upgrade. So checksum file has to be created for the image to be uploaded using below command

...

After checksum file is created, place this file in tftp location along with actual image file which is expected by firmware upgrade script. Without which firmware upgrade wont be allowed by scripts

Creating Multi-Boot compatible SD-CARD if RDKB is Flashed for first time

If RDKV is flashed for the first time, please ignore below procedure in current section

If firmware upgrade is intended for multi-boot, it is necessary to have partizion size matching to both RDKV and RDKB image size ( especially rootfs ). 

But size of RDKB image is around 300 MB approx, but RDKV is more than 1 GB. So it is necessary to have RDKB image flashed SD card should have partition compatible to RDKB.

To make compatible, size of RDKB rootfs partition should be increased to 2 GB ( 2098 MB) from 300MB default

This resize can be achieved using gpartedui tool which should be available in host pc

Please resize the rootfs partition to 2098 MB or 2GB (/dev/sdb1) accordingly from below procedure as captured in various stages

1. Select gparted tool from menu

3. Resize the rootfs partition by giving new size image to 2098 MiB
