Yocto Project and OpenEmbedded

OpenEmbedded

../_images/oe.svg

  • Created by merging the work of the OpenZaurus project with contributions from other projects such as Familiar Linux and OpenSIMpad into a common code base

  • Community project focusing on broad hardware and architectures

  • Large library of recipes to cross-compile over 1000 packages

  • Switched from flat meta-data architecture (OpenEmbedded Classic) to layered architecture based on OpenEmbedded Core layer, which is in common with the Yocto Project and the Ångström Distribution

Yocto Project

../_images/yp.svg

  • Family of projects for developing Linux-based devices

  • Self-contained build environment providing tools and blueprints for building Linux OS stacks

  • Supported by silicon vendors, OSVs (also providing commercial support), open source projects for hardware and software, electronics companies

  • Standardized components with compliance program

  • Focused on tooling and maintenance, major release every 6 months

Why not just use OpenEmbedded?

OpenEmbedded
