Showcase: Fail-Safe (OTA) Field Updating

Enrico Jörns | | didyouknow, rauc

Eingebettete Systeme und IoT-Geräte robust und sicher im Feld updaten zu können ist heute eine Kernanforderung jedes Produkts. Das Update-Framework RAUC ist die Basis für eine moderne und zukunftsfähige Lösung. In diesem Showcase zeigen wir die Grundprinzipien eines ausfallsicheren Update-Systems und wie Sie dieses mit Unterstützung von Pengutronix für Ihre Plattform realisieren können.


RAUC v1.5 Released

Jan Lübbe, Enrico Jörns | | RAUC

This release fixes a vulnerability in RAUC that can be exploited under certain circumstances to achieve a local privilege escalation. It provides both a mitigation for the vulnerability when using the existing bundle format as well as a new bundle format that uses dm-verity to continuously authenticate the update data while it is installed.


RAUC v1.4 Released

Enrico Jörns | | RAUC

It's been 3 weeks ago now since the tag for RAUC 1.4 was created. But it is vacation time and so we have a good excuse for communicating things with some delay. Fortunately, the media team is back now and so also those of you who haven't noticed the new release yet will be informed about notable changes.


ELC-NA 2020 - A Virtual Experience

Enrico Jörns, Jan Lübbe | | Event

In 2020, things tend to be a bit different from what we had before. This is also true for this year's Embedded Linux Conference in North America. The need for keeping physical distance required the Linux Foundation to switch form a real conference to a fully virtual one.


RAUC v1.3 Released

Enrico Jörns | | RAUC

Here it is, commit number 1700, 291 commits after the v1.2 tag: The v1.3 release of RAUC is out in the wild and adds a lot of new and useful features together with some fixes.


#FlattenTheCurve – Vorstellung unserer Remote-Infrastruktur

Die Corona-Krise hat uns alle, sowohl als Privatpersonen als auch als Firmen, plötzlich ziemlich hart getroffen und stellt unsere gesamte Gesellschaft vor neue Herausforderungen. Wir als Pengutronix möchten uns bei denjenigen bedanken, die in systemkritischen Berufen arbeiten und unsere alltägliche Versorgung sicherstellen.


Pengutronix at Embedded World 2020

Yesterday, Embedded World started, in normal times one of the largest trade shows for embedded development in Europe. While many exhibitors (and thus maybe also lots of visitors) have canceled their presence due to the coronavirus, we present our booth and our demo show cases as usual.


FOSDEM 2020 – Recommended Talks

Enrico Jörns, Chris Fiege | | Event

FOSDEM is one of the biggest Open Source community meetings in Europe and takes place in Brussels at the Université Libre de Bruxelles every year in February. For Pengutronix this is always a good chance to meet developers, discuss current topics and enjoy some Belgian beer and food. This year we attended FOSDEM with 15 colleagues. Here are some talks our colleagues recommend you to see.


OpenEmbedded Workshop 2020

Enrico Jörns | | Event

This year, co-located to the FOSDEM in Brussels, the first OpenEmbedded workshop was held. About 30 OpenEmbedded (and Yocto Project) enthusiasts - from the developers of the first hour to those still collecting their first experiences - got together at the DigitYser tech hub in Brussels. Pengutronix attended with their two developers most involved in OpenEmbedded: Jan Lübbe and Enrico Jörns.


RAUC v1.2 Released

Enrico Jörns | | RAUC

Right before the ELC-E starts tomorrow, we used the time in the hotel to bake a brand new RAUC release for you (and your embedded devices)! Well, here it is: RAUC v1.2


Safe and Secure Field Updates of Embedded Linux Systems

Enrico Jörns | | RAUC, OTA, Talk

In this blog post I would like to address the challenges of performing unattended and verified updates of embedded Linux systems in the field using open source software and workflows. While updating is not a end in itself, a second part of my considerations goes even further and also works out the necessities and possible workflows for keeping the software stack of a project up to date and thus either preventing security issues or at least enabling a short reaction time in case of severe CVE'S discovered.


CERT@VDE Innovation Workshop

Enrico Jörns | | Event, OSADL, RAUC, CERT@VDE

On June, 27th, while the sun was relentlessly heating up Germany as hardly every before, above 50 employees from many companies came together in a well air-conditioned room in the TP ConferenceCenter in Heidelberg. All operating in different fields of application but all involved in embedded systems and all interested to learn something new about security and deploying software updates.


RAUC v1.1 Released

Enrico Jörns | | RAUC

Just before the beautiful shine of the new has fully disappeared from RAUC 1.0, it is now time to bring out a new release: v1.1.


A Logo for labgrid

Enrico Jörns | | labgrid

It took us a while to find a good logo for one of our latest (but already quite-a-few-years-out) software projects, called labgrid. In case you have not heard of it yet, feel free to read our short blog post from 2017 or visit labgrid's GitHub page.


RAUC v1.0 Released

Enrico Jörns | | RAUC

Four days before Christmas Pengutronix prepared a very special present that probably many of you have been waiting for: The 1.0 version of RAUC!


RAUC v0.4 Released

Enrico Jörns | | RAUC

The RAUC team is proud to announce that we've just released RAUC v0.4!


Pengutronix auf der FOSDEM 2018

Enrico Jörns | | Event, Talk, RAUC

Wie auch in den vergangenen Jahren ist auch dieses Jahr wieder eine Horde Pengutronix-Entwickler zur alljährlichen Open-Source-Konferenz FOSDEM nach Brüssel gefahren, um sich dort über die aktuellen Entwicklungen in den Bereichen Embedded Linux, Graphik und Multimedia, Elektronik und anderen interessanten Bereichen zu informieren.


RAUC v0.3 Released

Enrico Jörns | | RAUC

The RAUC team is proud to announce that we've just released RAUC v0.3! Again, we have worked a lot on stability and support for more and more use cases. RAUC now supports pure UEFI-based booting on x86, multiple board variants in the same bundle, intermediate certificates and enhanced feedback from the boot selection layer.


PTXdist.org: Departure into a new Age

Enrico Jörns | | PTXdist

Over the past months, we did a lot of work in giving some open source projects maintained by Pengutronix folks the attention they deserve while also being more open to the community and ease contributing to and using them.


Bridging the Gap: The RAUC hawkBit Client

Enrico Jörns | | RAUC

OTA field updates are a common requirement in modern embedded device deployments. The larger the amount of devices to control, the more important is having a good infrastructure that is reliable in updating and smart in rolling out the software.


RAUC v0.2 Release

Enrico Jörns | | RAUC

Eine neue Version des RAUC Update Frameworks steht bereit.


Umfassendes RAUC Dokumentations-Update

Enrico Jörns | | RAUC, Documentation

Wie in vielen Projekten, ist auch bei RAUC an vielen Stellen nach massiver Entwicklung meist nicht mehr ausreichend Zeit geblieben, die Änderungen, neuen Features und grundlegenden Konzepte angemessen aufbereitet in der Dokumentation unterzubringen und zu erklären.


Pengutronix wird Yocto Project Participant

Enrico Jörns | | Yocto

Nicht zuletzt da das Yocto Projekt aus der Embedded-Welt schon seit längerem nicht mehr weg zu denken ist, setzt auch Pengutronix bereits seit einigen Jahren neben PTXdist in diversen Projekten auch OpenEmbedded erfolgreich als Distributions-Buildtool ein.
