Pengutronix at the Single Pair Ethernet Forum in Ludwigsburg
Single Pair Ethernet (SPE) is a set of new Ethernet standards in which communication works over a single pair of wires. Embedded Linux is ideally suited, especially for the smallest nodes connected via SPE. Pengutronix is a partner of this year's Single Pair Ethernet Forum in Ludwigsburg and will also be giving a presentation.
Embedded Linux and open source as the basis for long-lasting, smallest networked systems
Chris Fiege
Modern network technologies such as Single Pair Ethernet allow Ethernet to be used even in the smallest systems, such as sensors and actuators.
At the same time, the prices for processor functions have been falling for years, which now allows full-fledged operating systems such as Linux to be used even in these small systems. Simulataneously, however, regulations such as the CRA and other product standards require the timely fix of security vulnerabilities and long-term software support for certain products.
This talk will first demonstrate how long-lasting, maintainable products can be developed based on open source and Embedded Linux.
The talk will then examine which Single Pair Ethernet functions are already supported by Linux and what future developments are possible.

In dieser Folge unterhalten sich Oleksij und Leonard über Ethernet und seine verschiedenen (drahtgebundenen) Übertragungswege. Es geht viel über neue Single-Pair-Ethernet Standards (10Base-T1L, 10Base-T1S, 100Base-T1) und darüber was einem der Phy (der Baustein, der die digitalen Signale schlussendlich analog auf die Übertragungsleitung umsetzt) über den Zustand der Leitung mitteilen kann.
LXA USB-T1L ❤️ Beagle Play: Exploring Single Wire Ethernet
It seems everybody is talking about Single Pair Ethernet (SPE) these days. So we want to follow the trend and do the same :-) SPE is a class of Ethernet transmission standards that uses just a single pair of twisted pair cable for data transmission. There are multiple SPE variants spanning maximum data rates from a hand full MBit/s to multiple GBit/s and cable lengths from a hand full of meters to kilometers. The most interesting ones from our embedded-centric point of view are 10Base-T1L (point-to-point, up to 1 km), 10Base-T1S (multidrop, approx. 10 m) and 100Base-T1 (point-to-point, 15 m). The new Beagle Play comes with a 10Base-T1L PHY. This makes it a great peer to experiment with our Linux Automation USB-T1L. In this post we will explore the possibilities of 10Base-T1L on a recent Linux system.
Talks, Workshops, Time at the Beach - Embedded Recipes 2025
I was part of a small delegation of Pengutronixians at the Embedded Recipes conference this year in Nice, France. We had a great time there, so let's take a look back at the great talks we have seen, the labgrid workshop we held and our time in Nice in general.
Labgrid Hands-On Training at Embedded Recipes 2025
We are happy to announce that we are hosting a one-day version of our hands-on labgrid training at the Embedded Recipes in Nice, France. The workshop takes place on day three of the Embedded Recipes (16.05.2025) and is part of the workshop track. The workshop is free of charge, but registration is required.
Pengutronix auf den Chemnitzer Linux Tagen 2025
Wir freuen uns, auch in diesem Jahr bei den Chemnitzer Linux Tagen dabei sein zu können. Wie jedes Jahr sind die CLT eine willkommene Gelegenheit, Freunde zu treffen und sich über Linux, Open Source und den Rest der Welt auszutauschen. Auch in diesem Jahr stellen wir uns mit einem eigenen Stand vor und freuen uns, vier Vorträge zum Vortragsprogramm beitragen zu können.
