Michael Opdenacker, Founder of Root Commit, has published free and open-source training materials on OpenEmbedded and Yocto using the BeaglePlay SBC powered by a Texas Instruments AM625 processor. If the name rings a bell, it’s because Michael was the founder of Bootlin (previously Free Electrons) before selling the company to employees in 2021. He’s now started a new company called Root Commit, where he continues providing Embedded Linux training and development services. He’s kept the tradition of releasing free training materials, with the latest course being related to Yocto development on the BeaglePlay board. You’ll find resources on the Root Commit website with three files, including 220 pages of lectures, 18 practical labs for the BeaglePlay board and QEMU, and source code/patchsets released under a Creative Commons BY-SA 4.0 license. The course includes an introduction to the Yocto Project 5.0 and Embedded Linux, a Getting Started guide explaining how to create a recipe, use BitBake, and build an image for an emulated ARM64 machine, and more detailed instructions for Yocto recipes and layers. Slide from the Lectures PDF You can try to follow the tutorials by yourself, or join a four-day online course taking place online on September 2-5 or 9-12, with 25% theory and 75% practical activities for a total of 32 hours of learning. While the materials are free, attending the online course costs 1995 Euros.

simplest-yocto-setup is an example of the simplest, but realistic and working, Yocto/OpenEmbedded setup. It aims at providing an example of how Yocto/OE can be used as the embedded Linux build system for end products without unnecessary complications. While working for several Bootlin customers on their Yocto/OpenEmbedded setups we have seen many problems caused by unnecessary complications in their layers. We have spent a lot of time in educating to writing clean layers, which…

> Tilck is an educational _monolithic_ kernel designed to be Linux-compatible at binary level. It runs on i686 and RISCV64 at the moment. Project’s small-scale and simple design makes it the perfect playground for playing in kernel mode while retaining the ability to compare how the _very same_ _usermode bits_ run on the Linux kernel as well. That’s a rare feature in the realm of educational kernels. Because of that, building a program for Tilck requires just a gcc-musl toolchain from bootlin.com. Tilck has no need to have its own set of custom written applications, like most educational kernels do. It just runs mainstream Linux programs like the BusyBox suite. While the Linux-compatibility and the monolithic design might seem a limitation from the OS research point of view, on the other side, such design bring the whole project much closer to _real-world_ applications in the future, compared to the case where some serious (or huge) effort is required to port pre-existing software on it. Also, nothing stops Tilck from implementing custom non-Linux syscalls that aware apps might take advantage of. > > ↫ Tilck GitHub page Tilck implements about 100 Linux syscalls, and is not focused on replacing the Linux kernel or even becoming a generic desktop or server operating system. It supports both i686 and RISC-V, has support for FAT, and a whole slew of other features. It can run a number of console and even a few framebuffer applications, but don’t expect things like X11 to work, or to ever work.

AAEON announced that full mainline Linux support for the 40-pin Raspberry Pi-compatible GPIO header on its UP Squared series has been merged into Linux 6.18. The work, completed in collaboration with Bootlin, removes the need for the previously required out-of-tree DKMS driver. The UP Board family combines Intel processors with a 40-pin expansion header routed […]
