Introduction

Our Workflow as below

WISE-OTA

Server

Here we can upload our update package and depoly to devices

http://wise-ota.eastasia.cloudapp.azure.com/

Agent

Our devices need to install OTA agent by default, so that devices can connect to OTA server.

OTA PACKAGE TOOL

This software is a package tool for WISE-PaaS/OTA system. You can use this tool to generate an OTA package which can be identified by the WISE-PaaS/OTA system based on your original update resources.

Architecture

Bootloader

It can detect the Update Flag is enabled or not

If flag is true ,it will enter Recovery System

If flag is false,it will enter Main System

System

We need two systems in our image.

One is Main System , another is Recovery System.

Both Systems have a specific script for FOTA.

• Main System

do_update.sh

This script has three functions

1. Record upgrade package file path
2. Set Upgrade Flag
3. Return OTA result

• Recovery system

adv-ota.sh

This script has two functions

1. Parse upgrade package and upgrade main system
2. Clear Upgrade Flag, and reboot

Cache

For storage of downloaded OTA upgrade packages

Upgrade Packages

ota-package.sh

Generate package file to be used for OTA update on Yocto Linux

Usage: ota-package.sh [OPTIONS]

Generate package file to be used for OTA update on Yocto Linux

-b <file>  Bootloader image file
-k <file>  Kernel or Boot image file
-d <file>  DTB (device tree) file
-r <file>  Rootfs image file
-o <file>  Output file
-h         Show help

Platform

Depending on the platform, we have different modifications for FOTA

i.MX6

• Layout

Take 4G size as an example

1. We add misc partition to store upgrade flag
2. We can only upgrade boot and rootfs partition so far

• Kernel
• Device tree
• Root file-system

•  Workflow

The step for setting upgrade flag here is to write BCB to misc partition.

Then bootloader will detect the content of BCB, if the content is "boot-recovery" then system will boot to recovery system.

Quark

QCOM

Upgrade Steps

Online Upgrade

• Step 1

Use package tool to generate ota package file

Put update.zip (generate by ota-package.sh) in the same folder.

Set the relevant settings and generate ota package.

• Step 2

Upload ota package

Push upload button to upload ota package

• Step 3

Check whether the device has connected to server

If the device connect to server, the host will show your device

• Step 4

Upgrade system

Push upgrade button and select ota package

We can see the message via debug port

Local Upgrade

• Step 1

copy update.zip to cache

cp update.zip /cache/

• Step 2

enter /cache/

cd /cache

• Step 3

set flag and set recovery command

/tools/do_update.sh update.zip

• Step 4

reboot

• Step 5

Enter recovery system and upgrade

• Step 6

Enter main system and check result

/toos/do_update.sh result
OK
