Our contributions to Yocto 4.3

Yocto Project logo

The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded system deployments in connected edge devices, servers, or virtual environments, regardless of the hardware architecture. Yocto 4.3 (codename “nanbield”) was recently released. It includes Linux kernel 6.5 and 6.1, gcc 13, glibc 2.38, LLVM 17, and over 300 other recipe upgrades.

BayLibre engineers made the following contributions to Yocto 4.3:


We contributed a total of 82 patches across several areas:
