New Release:
TorizonCore 5.5.0 Quarterly Release

Tuesday, January 18, 2022


We are pleased to announce the TorizonCore 5.5.0 quarterly release for Toradex's System on Modules.

TorizonCore is our operating system that powers Torizon, a DevOps platform that simplifies the development and maintenance of embedded Linux software. TorizonCore is designed to be used out-of-the-box on devices requiring high reliability, allowing you to focus on your application instead of on 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 5.x.y TorizonCore releases.

Updates and Highlights

    1. The client implementation, which is expected to be different for different vendors
    2. libaktualizr, the core functionality that is used by the client implementations

To enable new features, such as secure offline updates, Toradex now is leveraging Aktualizr by making changes to libaktualizr on a forked repository until these changes are upstreamed. Previously, we were applying patches on the code from the upstream repository. This move will allow Toradex to implement new features and bug fixes to libaktualizr more dynamically.

  • Update of TorizonCore packages
    The following packages have been updated:
    • Fluent-bit updated to 1.8.9
    • Podman updated to 3.4.1
    • Common updated to 2.0.30
    • FUSE overlay updated to 1.7.1
Debian Packages and Containers

    This release is intended to be used in production on these modules.
  • Sample products: Apalis iMX8, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M Plus
    Due to the hardware status of samples, this release is intended for development.
