As embedded Linux devices get more complex, many questions arise about the process of constructing these systems and how it can be improved. Can these complex systems be built more efficiently to reduce development time? How can developers be assured that these systems can be built reproducibly to ensure software supply chain integrity? Joshua will highlight two new features in the latest release of the Yocto project specifically designed to address these questions.

Recently I was tasked to create a bare metal toolchain to create software for a variety of embedded processor architectures and configurations. Crosstool-ng is often used to create these toolchains, but Yocto Project SDK builder is capable of doing this as well. This presentation will compare both crosstool-ng and the Yocto Project for this task, include my experiences working with both tools, include Yocto Project configuration information and give the audience an understanding when they may want to use one tool vs the other.

Multiarchitecture SoCs are more widely used, usually containing a large architecture where it can run a full operating system such as Linux, and one or more small architectures designed to run an RTOS or a baremetal application,requiring less hardware resources,leveraging suitable tasks from one to another creating a more efficient product. While the Yocto Project is well known for its capabilities on creating customized Embedded Linux Distributions,bitbake is also capable of building a toolchain to create Baremetal applications or an RTOS.
