Pengutronix Becomes Yocto Project Participant
Not at least since the Yocto project cannot be thought away from the embedded world, Pengutronix successfully also uses OpenEmbedded next to PTXdist as a distribution build tool in various projects for several years.
Since then, we have always been as close as possible to the widely spread community, either through participation in conferences such as the OEDEM, various BoFs at the Embedded Linux Conference Europe or through discussion and contributions on the various mailing lists.
With meta-rauc, the Yocto Layer for the Open Source Update Framework RAUC, Pengutronix works closely with the community on one of the key components for modern and secure embedded systems.
We are pleased that now with the official listing as Yocto-Project Participant our contributions to the Yocto and Embedded community are visibly appreciated. We take this as a further incentive, to continue improving the reproducibility, stability and security in the development of embedded Linux system through robust build tools such as PTXdist or OpenEmbedded.

Signed FIT Image Support for meta-oe (fitimage.bbclass)
FIT images provide a versatile way to bundle components used to boot embedded Linux systems, like the kernel, device tree, ramdisk, firmware, etc. They also support cryptographic signatures, making them ideal for verified boot setups. This blog post introduces the new fitimage.bbclass in meta-oe as an alternative to oe-core's kernel-fitimage.bbclass, with a clear focus on enhancing both versatility and signing support.
