59. Putting firmware on the device: a Zephyr+Yocto+Mender hike

Mr Josef Holzmayr

14/09/2022, 10:00

One of the biggest real-life challenges for embedded developers is putting the various bits and pieces of technology together to form an actual product. Usually, each component offers good documentation and resources to get started, but documentation examples that encompass bigger, interconnected parts of a pipeline are often hard to come by.

In this presentation, we will start by building...

212. Open source FPGA NVMe accelerator platform for BPF driven ML processing with Linux/Zephyr

Karol Gugala (Antmicro)

14/09/2022, 10:25

The talk will describe an open source NVMe development platform developed by Western Digital and Antmicro for server-based AI applications. The system combines an FPGA SoC with programmable logic and an AMP CPU, running Zephyr on the Corex-R cores handling NVMe transactions and Linux on Cortex-A in an openAMP setup.

The system utilizes Zephyr RTOS to perform time critical tasks including...

240. Abusing zephyr and meta-zephyr

Eilís Ní Fhlannagáin (Oniro Project)

14/09/2022, 10:55

This talk will talk about the work done to switch from cmake to west in meta-zephyr and how I leveraged this work to do bad things with zephyr and meta-zephyr to generate Yocto Project machine definitions for meta-zephyr. We'll discuss why these patches are not zephyr upstreamable and why autogenerated machine definitions are not included in meta-zephyr.

244. libgpiod V2: New Major Release with a Ton of New Features

Bartosz Golaszewski (BayLibre)

The linux GPIO subsystem exposes a character device to the user-space that provides a certain level of control over GPIO lines. A companion C library (along with command-line tools and language bindings) is provided for easier access to the kernel interface. The character device interface has been rebuilt last year with a number of new ioctl()s and data structures that improve the user...

96. Linux IEEE 802.15.4 MLME improvements

Miquèl Raynal

14/09/2022, 12:05

As of today, Linux has relatively poor support for 802.15.4 MLME operations such as scanning and beaconning. These operations are at the base of beacon enabled PAN (Personal Area Networks) where devices can dynamically discover each other, associate to a PAN and maintain it as the devices move relatively to each other.

While some embedded RTOS like Zephyr already have a quite featureful...

246. All types of wireless in Linux are terrible and why the vendors should feel bad

Peter Robinson (Red Hat)

14/09/2022, 12:35

The wireless experience in Linux is terrible, whether it be 802.11, bluetooth or one of the other random standards we support? Why is it so bad? One word... Vendors! Vendors do the bare minimum, regress for "stable" users, either rarely or never update or even ship appropriate firmware and expect us to just accept it! This is the perspective of a linux-firmware maintainer for a distribution...

243. Libre Silicon in IoT

Michael Welling

14/09/2022, 13:00

Few have achieved what many would have thought impossible; bringing together a distributed community of engineers, then designing, prototyping, and fabricating a custom RISC-V SoC. The project was largely a success - in the first revision no less!

Designated PyFive, the intent was a libre silicon MCU capable of easily running Micropython and CircuitPython. It was designed and tested from...
