FOSDEM

Traditionally, the open source community meets for its annual meeting in Brussels at the beginning of February - In 2021 however, beer and waffles had to be consumed at the desk at home. Yummy :-)

The exchange took place via online lectures and the matrix messaging protocol. Of course, waffles will be baked in the kitchen at home again in February 2022.

Our Contributions:

• About the joy and tears of testing Embedded Devices (C. Fiege)
• The road to the mainline ZynqMP VCU driver (M. Tretter)
• From Reset Vector to Kernel - Navigating the ARM Matryoshka (A. Fatoum)

Chemnitzer Linux Tage

The CLT learned from the Chaos Computer Club and pixelated the lecture hall building in a workadventure. The result was a real conference experience where people spontaneously met and chatted in the corridors. At every corner, lovely designed details or participants streaming videos of their guinea pigs surprised everyone.

The world was complemented by numerous lectures and Big Blue Button rooms, offering workshops or lightning talks.

We are looking forward to the implementation in 2022 and will be there again with the Pengutronix Quiz with questions about Linux, open source and embedded topics.

building IoT

"building IoT is the trade conference for IT professionals developing applications and products in the Internet of Things and IIoT."

We would like to thank the speakers for their excellent support during the conference and for the interesting selection of topics. We look forward to attending building IoT in the future.

OSADL COOL

The monthly online conference programme of Open Source Development Lab (OSADL) has become an integral part of the Pengutronix team's schedule.

In the editions, various topics relating to open source software in the industrial environment are discussed and debated. The structure follows the pattern: introduction to the topic by an overview lecture, followed by an expert lecture and subsequent discussion.

Our Contribution:

• Security requirements of embedded systems with special emphasis on field update (J. Lübbe)

Live Embedded Event

The Live Embedded Event is another format that has emerged during the pandemic to gather the embedded community.

As the conference is initiated and hosted by our colleagues from France, the conference language is mixed French and English.

Our Contribution:

• The Woos and Woes of Open-Source FPGA-Tools: A journey (S. Trumtrar)

Digitaltag

"Over 2,000 actions nationwide and 4,325 hours of programming across Germany and in virtual space. That was Digitaltag 2021!"

For Hildesheim, we looked at the question of how to transform a city into a "smart city". To do this, we first looked at LoRaWAN as a technical building block for a smart Hildesheim and then tried to work out what a smart city can learn from Freifunk as a community project.

Our Contribution:

• Smart City - vom Rapid Prototyping bis zur Tragfähigen Infrastruktur (C. Fiege, L. Göhrs, R. Schwebel)

FPGA-Conference Europe

The FPGA Conference is aimed primarily at industry with specialist presentations on the development of FPGAs. The focus was on supply chain security, AI and edge computing with a focus on concrete product solutions.

Our Contribution:

• Your product is broken, and you don't know - An uncomfortable truth (M. Tretter)

FrOSCon

The summer meeting of the German-speaking open source community also took place online in 2021. In ~ 36 hours lecture recordings, experiences with working in a home office, security vulnerabilities, entry possibilities into open source development are conveyed. A new addition is the category "Woodworking instead of IT" about hobbies and compensation possibilities that speakers have tried out and discovered during the COVID-19 contact restrictions.

Our Contribution:

• DOOM portieren für Einsteiger: Heavy Metal auf Bare Metal (A. Fatoum)

ELC-E

This time the ELC-E was not only a conference in Europe, but a hybrid event in the USA with guests from all over the world, on site and via the internet.

Understandably, it is difficult to accommodate all sleeping habits when a global audience gathers at a conference. Thanks to a spontaneously provided Jitsi, a technically sound exchange among the participants was well possible, but nevertheless this can hardly replace the discussion in the corridors. We are therefore very much looking forward to meeting again live at the next ELC-E conference.

Our Contributions:

• Initializing RISC-V: A guided tour for ARM developers (A. Fatoum, R. Czerwinski)
• Teach an old network driver new tricks (O. Rempel)
• Automated Testing for Embedded development: Next generation Board Farming (C. Fiege)
• Building Open Hardware with Open Software (M. Tretter)

ESE-Congress

The Embedded Software Engineering (ESE) Congress describes itself as the leading congress for the embedded industry. In addition to an extensive track on management and team leadership, the congress offers basic lectures in many relevant areas of embedded development, such as test automation and code quality.
