Introduction

Every embedded Linux OS has few remarkable pieces of software, in this article referred to as components, that are very important to understand the overall system status with regards to performance, known and fixed issues, build instructions, among other aspects.

It is nearly impossible to always use the same versions of components for all of the Toradex computer on modules, therefore this article aims to give you a consolidated overview about the versions of the most remarkable components of our embedded Linux offerings: the Linux kernel, U-Boot and Yocto. You can skip this introduction and go straight to the active release matrix, though we recommend that you read everything at least once.

Toradex Embedded Linux Offerings

Toradex provides two options for embedded Linux development:

• Toradex BSP Layers and Reference Images for Yocto Project.
• TorizonCore

• 

  Relationship between TorizonCore, BSP Layers and Reference Images

TorizonCore and the Reference Images are built on top of the BSP layers, therefore both offerings share the same versions of components for a fixed release. In the past, those have diverged and the alignment between TorizonCore and the BSP Layers for Yocto Project is only guaranteed from the release 5 onward. We might provide a separate release matrix for each offering until they are both aligned.

Embedded Linux Release Details

This article is a summary, it does not replace the release details for Toradex embedded Linux offerings:

• Toradex BSP Layers and Reference Images for Yocto Project Release
• TorizonCore Release

Source-code and Build Instructions

The Reference Images for Yocto Project are not meant to be used as-is, this is why we name them reference images. You must use the Yocto recipes they are built from to create your own distribution. Learn more about it in the article below:

• Build a Reference Image with Yocto Project

On the other hand, TorizonCore is a binary distribution and you shouldn't need to rebuild it from the source in most cases. Nevertheless, if you really need to you can follow the article below:

• Build TorizonCore With Yocto

Prerequisites
