This document describes the firmware update of RPI board using FirmwareControl plugin.Plugin can be enabled via controller UI once image is booted. Based on the request given to board, tarred firmware image is downloaded to RPI board from the given HTTP server and the image is updated accordingly.
The build procedure is as follows:
Image is flashed to SD card before inserting to RPI board.
sd-card size requisite It is must to have minimal size of 8GB SD-Card for Firmware upgrade support |
Command to flash the image
Generated image has to be flashed to an SD card using this command in local PC:
$ sudo dd if=<path to ImageName.rpi-sdimg> of=<path to SD card space> bs=4M
Ex: $ sudo dd if=rdk-generic-hybrid-thunder-image_default_20200302130659.rootfs.rpi-sdimg of=/dev/sdc bs=4M |
The SD card is then inserted to the Raspberry Pi board and booted to check for containers created.
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
For testing Firmware Control plugin , we need HTTP server that hosts the tarred image.
Enabling the FirmwareControl Plugin:
FirmwareControl plugin is enabled or disabled via Controller UI. Controller UI is launched using browser via http://<board ip>
Ex: http://192.168.2.20
Upon booting the image, firmwareControl plugin will be disabled
Plugin needs to be enabled before proceeding with firmware update.
