Torizon OS Updates Overview

Introduction​

This article brings an overview about the OS Update procedure with Torizon Cloud and devices running Torizon OS.

When You Should Update​

Toradex maintains updated software stack, including the bootloader, and Linux Kernel.

You can follow the Torizon OS Issue Tracker and the BSP Layers and Reference Images for Yocto Project Issue Tracker pages to get updated information about known issues, scheduled bug fixes, and feature improvements for every Torizon OS and BSP release. Remember that Torizon OS is built on top of the Toradex BSP.

Vanilla Torizon OS Packages​

With the Torizon Cloud, you can update the Torizon OS version of the boards remotely with the latest periodical releases. To do that, when adding a new package, select the option "Custom Package" and then select the desired release type (Release, Monthly or Nightly) for the same base image that is currently installed.

Select the package

Custom OS Updates: Custom Torizon OS Packages​

In some cases, when you need to customize the base Torizon OS image, the Torizon Cloud can receive your custom image and send its updates to your fleet of devices. Some examples where image customization is required include, but are not limited to:

  • Adding new Hardware by customizing the system's device tree
  • Changing the System's Splash Screen
  • Capturing Changes in the Configuration of a Board

In this situation, a developer uses TorizonCore Builder Tool to generate a custom image.

Also, in some corner cases, the image re-building and customization are inevitable. Torizon OS is open source, and Toradex provides instructions to build Torizon OS with Yocto.

In any customization case, you can use Torizon Cloud to update the OS of your device in the field:
