We are pleased to announce the Torizon OS 6.6.1 quarterly release for Toradex's System on Modules.

Torizon OS is our operating system that powers Torizon, a DevOps platform that simplifies the development and maintenance of embedded Linux software. Torizon OS is designed to be used out-of-the-box on devices requiring high reliability, allowing you to focus on your application instead of building and maintaining an operating system.

Torizon uses software containers, making it simple to add functionality to your system in a way that is both secure and easy to maintain. Torizon supports hardware acceleration in containers and graphical user interfaces.

This release includes all updates from the previous 6.x.y Torizon OS releases.

Intended Use

The Torizon OS 6.6.1 Quarterly Release is a production-grade release.

Therefore, if you are in production with TorizonCore 5 or earlier Torizon OS 6 releases, we recommend moving to this quarterly release. Read the details on our Torizon OS Upgrade Notes.

Hardware Support

A quarterly release is a production release, intended to be used in a production environment only with volume products, as long as they are supported by Torizon OS . We run a set of tests to validate them. Learn more about our release types from our Embedded Linux Support Strategy.

• Volume products: Verdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX6, Apalis iMX8, Colibri iMX6ULL 1GB, Colibri iMX6DL, Colibri iMX7D 1GB, and Colibri iMX8
  This release is intended to be used in production on these modules.
• Sample products: Verdin AM62
  Due to the hardware status being “sample”, this release is intended for development.
  For Verdin, only the second generation of Verdin products is supported.
