Talk: Long Term Maintenance at Embedded Recpies (Paris)
While the technical side of building embedded Linux systems is mostly solved, running such systems connected to the internet over a long time has its own challenges. At the Embedded Recipes Conference in Paris, Marc Kleine-Budde will talk about establishing a sustinable workflow for this usecase tomorrow (2017-09-26).

Wir wollen zum Bundesweiten Digitaltag am 18.6.2021 das Thema "Smarte Städte" ein bisschen von der technischen Seite beleuchten, aber keine Angst: es bleibt für alle verständlich.
Distributionen wie Raspbian lassen die passgenaue Zusammenstellung eines Betriebssystems kinderleicht aussehen. Image herunterladen, Pakete installieren, noch ein paar Änderungen - fertig. Alles wie auf dem Laptop oder Server. Warum ein Betriebssystem aus einer klassischen Distribution im Produkt-Kontext zur Katastrophe führen kann, beleuchtet der Vortrag "Raspbian vs. Build-Systeme: Das richtige Werkzeug für solide Produkte".
A firmware upgrade is due. A newly implemented feature needs to be rolled out, a security issue patched or new hardware support added. The software, while capable, is complex. Pengutronix' strategy to handle this complexity is working on a version- controlled Board Support Package (BSP) with continuous updates and tests on the latest mainline Linux kernel.
"FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. In 2021, they will gather online." -- FOSDEM
Now that, due to the COVID-19 pandemic, everyone has gotten used to digitalisation and online conferences - it has never been easier to organise a conference and bring together all experts and interested parties for a few hours of intensive exchange of ideas on a certain topic.
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.
Today it has been 15 years since we mainlined support for Freescale/NXP's i.MX architecture in the Linux kernel! That was one small step for [a] man, one giant leap for (industrial Linux users') mankind :-) Here is some background about why it happened and what you might want to learn from history for your next embedded Linux project.
