labgrid is going on a live tour!

labgrid makes it possible to remote-control embedded linux devices and to implement integration tests of a complete embedded Linux system on real hardware. The Pengutronix developers and other companies have been using labgrid as a centerpiece of their embedded software development infrastructure to great success for quite some time now.

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.

Pengutronix at Electronica 2024 in Munich

Electronica trade fair in Munich, Germany is just around the corner and Pengutronix is currently gearing up to showcase some of our latest topics and developments. You find us in Hall B4 Booth 102 (map).

Bringing Barebox into OE-Core (Yocto)

This blog post chronicles the multi-year journey to get Barebox accepted into OE-Core—from the early attempts to the eventual success in October 2024. Along the way, we’ll explore the technical hurdles we faced, the community discussions that shaped the process, and the improvements we added to both OE and Barebox.

The USB-SD-Mux is now FAST

We have been distributing the USB-SD-Mux with our partner company Linux Automation GmbH since 2019. This has enabled us to make work easier for many embedded developers and improve software quality. At the same time, technology is advancing: micro SD cards are becoming faster and USB-C is now established as the standard.

Managing Complexity with Open Source

A few days ago, something exciting happened: I revisited my very first embedded system - a 34 year old stepper motor controller, driving the telescope mount of the Public Observatory Rothwesten, which was built by me back when I was in class 12 in highschool. Comparing those embedded systems from back in the days with the recent industrial systems, it is impressive to see that the latter ones are not manageable any more without the use of open source software.
