Default Overlays

Introduction​

This article presents information relevant for building images with Toradex BSP Layers and Reference Images, such as Yocto branches, manifests, Yocto build parameters and others. This article is not meant to be followed linearly, and instead supplements other pages.

If you wish to build a reference image with Yocto for your SoM, refer to: Build a Reference Image with Yocto Project/OpenEmbedded.

Device Tree Overlays​

See below the Device Tree Overlays for different functionality provided by Toradex for each SoM. For more details, check our Device Tree Overlays Overview.
