Smart City - vom Rapid Prototyping bis zur Tragfähigen Infrastruktur

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.


Yocto Project Virtual Summit 2021

Enrico Jörns | | Event, Yocto
On Tuesday, 25th and Wednesday, 26th, the 3rd edition of the Yocto Project Virtual Summit took place on the internet. With a fair ticket price of 40$ Pengutronix developers Jan Lübbe and Enrico Jörns got a 2-day long wild ride through the latest features, workflows and experiences with the Yocto Project.

The LXA IOBus line of lab automation devices

I would like to present to you the LXA IOBus, a CAN-based ecosystem consisting of a protocol, a gateway server and new class of Linux Automation GmbH devices, including the Ethernet-Mux and the 4DO-3DI-3AI input/output board.


Wie man (k)ein Betriebssystem für Produkte baut

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".


CLT-2021: Mach es einfach anders!

Marie Mann | | clt, linux, opensource

"Mach es einfach anders!" - unter diesem Motto finden die CLT dieses Jahr im virtuellen Raum statt. Wie auch in den letzten Jahren ist Pengutronix als Sponsor dabei. Anders ist, dass wir dieses Jahr unser eigenes kleines Programm mit spannenden Kurzvorträgen und täglich zwei Quiz-Runden mit tollen Hauptgewinnen mitbringen.


Showcase: Fail-Safe (OTA) Field Updating

Enrico Jörns | | didyouknow, rauc

Being able to robustly and securely update embedded systems and IoT devices in the field is a key requirement of every product today. The update framework RAUC is the basis for a modern and future-proof solution. In this showcase we present the basic principles of a fail-safe update system and how Pengutronix can support you with implement this for your platform.


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.


Showcase: Preempt RT and Time Sensitive Networking

Nowadays, even small and cheap microcontrollers offer enough calculation power to perform time critical tasks within an industrial environment. However, as soon as actors and sensors are spread over an entire facility and are to be connected over Ethernet, the actual moment when a data packet will get processed becomes very hard to predict. At this point, Linux running a Preempt RT Kernel altogether with a network featuring Time Sensitive Networking (TSN) capabilities can help.


Showcase: Embedded off-the-shelf

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.


Showcase: Remote Working

Project work with our customers includes the handling of hardware prototypes. Since work is generally done in parallel, on many project for many customers, there is a constant flood of hardware prototypes accumulating on the desks of our developers. These accumulations of loose boards can become a problem. This is especially the case when a number of people work on a prototype. Another common annoyance occurs when a project has not been worked on for a period of time, as this might involve moving the hardware from one desk (or storage location) to another and setting it up again. Right now, in a situation where working from home is more common and relevant than ever, this has become even more of an issue. The distances between desks and storage locations of our developers are now measured in kilometers, rather than meters.
