Pengutronix at FrOSCon 2018
This year, a team from Pengutronix attended FrOSCon in St. Augustin for the first time. We took the opportunity to shake hands, talk about our latest developments and meet hackers interested in working with embedded Linux.
To show some of our work, we brought a demo for updating embedded devices with RAUC and hawkBIT and a Video Demo based on a fully open-source graphics stack with Etnaviv, Weston and GStreamer, cycling through four of the Blender Project's Open Movies in HD resolution.

Our hardware hacker had some fruitful discussions about electronic designs and possible use-cases for tools like our USB-SD-Mux, that makes the annoying juggling of SD cards between development host and target hardware a remnant of the past. When we started with that project, we would never have guessed that there was such a high demand for such a device, but from the large number of interested questions we gather that this is a niche that needs to be filled.
We also recognize that testing embedded devices is becoming an increasingly important and visible subject in the community. This motivates us to continue our efforts around this topic.
Besides that, our Penguin stickers and black pencils were popular as usual ;)
We'd like to thank FrOSCon Team for this great conference.
Further Readings
RAUC v1.9 Released
"Getting things off the ground" could be the motto for the v1.9 release of RAUC. The support for custom metadata in the manifest got a step further, a new, more flexible, D-Bus API for bundle inspection paved the way for obtaining more detailed information, and a new manifest hash marks the first of several planned changes for configurable event logging. However, one of the most invasive changes happened under the hood: We have started the transition from autotools to meson as a build system.
Chemnitzer Linux-Tage 2023
After the Corona break, the Chemnitzer Linux-Tage will actully take place in real life again, and the Pengutronix team will have eight (!) talks there.
FOSDEM 2023
The Pengutronix team is on it's way to FOSDEM in Brussels! We are looking forward to many interesting discussions with developers of different open source software components - be it the Linux kernel, Debian, KiDAC, FreeCAD etc ...
Netdevconf 0x16
After a longer time with online-only events, the Netdev 0x16, a conference about the technical aspects of Linux Networking, was organized as hybrid event: online and on-site at Lisbon.
Pengutronix at Electronica in Munich
This year Pengutronix again has a Booth at the Electronica trade fair in Munich, Germany. You find us in Hall B4 Booth 104 (map).
Saving Download Bandwidth with RAUC Adaptive Updates
Based on RAUC's HTTP(S) streaming capabilities, adaptive updates are a generic concept in RAUC to allow saving download bandwidth and form an alternative to conventional delta updates. This post introduces both the generic concept as well the first implemented method 'block-hash-index'.
RAUC v1.8 Released
When September ends and summer is over, it's a good opportunity to take advantage of the shorter days and comfortably update to the latest RAUC version we have just released into the wild: v1.8
rsc's Diary: ELC-E 2022 - Day 4
Friday, the last day of ELC-E 2022, is traditionally the day of the Embedded Linux Closing Game, with Tim Bird reporting about the embedded Linux world (universe?) domination progress and the overall state of the union. Of course, there were again several interesting talks.
rsc's Diary: ELC-E 2022 - Day 3
The Convention Centre is directly at the water front of the Liffey river, just a few walking minutes away from O'Connell Bridge, Temple Bar and Trinity College. Visiting ELC-E is always a good opportunity to visit interesting cities in Europe. However, here is my story of the talks I heard on day 3.
Showcase: Graphics on i.MX8MP
Enabling the graphics output pipeline on the i.MX8M Plus (i.MX8MP for short), is the most recent example on how open-source and upstream driver support for GPU and display engines can reduce effort and risk in a new project.
