First Steps with Torizon Remote Updates

Introduction​

This article directs you through the steps on how to use the Torizon Remote OTA feature.

What is the Torizon Secure Remote Updates Feature?​

Remote Updates is a feature of Torizon Cloud that delivers over-the-air (OTA) updates to devices running Torizon OS. It is an alternative to Torizon Secure Offline Updates, and both features share the same technology stack: OSTree and Aktualizr.

Read the Remote Over-the-Air Updates Overview for a broader view of the feature. For details about the underlying technologies, see the Torizon Updates Architecture.

Prerequisites​

In order to perform remote updates, you should have:

First Steps​

Create the Packages​

The first step is to bring your OS Image/Application to the Torizon Cloud domain. Learn how Torizon manages Software Packages reading the Feature Overview

Create a Torizon Application Package from the web UI, TorizonCore Builder or an IDE with Extension for Torizon:

Remember that you also need to push your application to a Docker registry, so the device can download it.

To create a Torizon OS Package, you should use TorizonCore Builder to push images built by you or other collaborators. Remember, you can always use Toradex's provided images out-of-the-box.

Initiate the Update​

The next step is selecting the components in the Torizon Cloud. You can choose any supported software package: subsystem, bootloader, OS and/or Application to be updated in a single device or in an entire fleet. When you initiate an update, it means that the target device or the devices in a fleet have a new update to process when it goes online and reaches the Torizon Cloud.

Deploying the Remote Update​

The provisioned devices periodically search for newly available instructions and update packages on the server. The next time any device addressed for updates goes online it downloads, validates, and deploys the update.

The update process is fully automated and no user intervention is required at any time, unless configured to do so. If you are performing an OS or synchronous update, the board automatically reboots once.

Control Updates on Target Device​
