Konsulko connects RDP with Wayland, Weston & Yocto at FOSDEM

Taking place February 4 & 5, 2023 in the beautiful city of Brussels (Belgium), FOSDEM is a two-day event organized by volunteers to promote the widespread use of free and open source software.

This year, Konsulko Group senior software engineer Leon Anavi will present Ups and Downs with Remote Desktop Protocol (RDP) on Wayland, Weston and the Yocto Project.

Leon’s tutorial provides the exact steps to build-from-scratch core-image-weston, setup RDP and remotely access the embedded device using wlfreerdp (for Wayland) or xfreerdp (for X11) from a personal computer with Linux in the same network. Examples will be based on the kirkstone long-term support release of Yocto Project.

Leon will also discuss the advantages and the disadvantages of RDP as well as some troubleshooting guidelines.

If you are attending FOSDEM, be sure to to catch this lightning talk at the Embedded, Mobile and Automotive devroom on Saturday.

Konsulko Group brings security focus to ELCE Dublin

At the Embedded Linux Conference in Dublin, Ireland, September 13-16, 2022, Konsulko Group’s Tim Orling will present “Tales from the Crypt: Implementing Secure Boot and Disk Encryption on Tegra Platforms.” Learn about the challenges and successes implementing effective security on Nvidia’s Tegra.

Secure Boot challenges

“Secure boot” needs different implementations on different platforms. For Tegra platforms, secure boot involves a one-time only burning of keys into the on-device fuses. Tim will share a reliable approach to confidently secure boot into the vendor’s Ubuntu-based OS before creating a Yocto Project-built OS.

Disk encryption with LUKS and dm-crypt

Extending this approach to disk encryption – testing the vendor’s OS before moving on to creating our own, Tim attempted to stay as close to the vendor’s tools (luks-srv and luks-srv-app) and design as possible, to try to “future proof” the implementation for newer releases of Linux for Tegra.

Extending for Over-the-Air updates

A/B flashing for OTA updates (e.g. rauc or mender) added additional challenges, generalizing the approach for the meta-tegra community. The end solution must address the bootloader, initramfs, kernel command line, /etc/crypttab, /etc/fstab and more. Add in the complexity of the partition table layout and flashing tools for Tegra platform, and it can be a wild ride.

Dublin and ELCE

The city of Dublin, Ireland has a storied history of literature, music and beverage. In September, Dublin will play host to the Embedded Linux Conference, Europe (ELCE), part of the Linux Foundation’s Open Source Summit.

Launched in 2005, Embedded Linux Conference is for companies and developers using Linux in embedded products. It gathers the technical experts working on embedded systems and applications for education and collaboration, paving the way for transformation in these important and far reaching areas.

Software Update Mechanisms

On Wednesday, June 22 at 2:35pm CDT (Texas time), Leon Anavi will present How to Choose a Software Update Mechanism for Embedded Linux Devices.

This talk will look at the advantages and disadvantages of widely-used industry approaches: A/B updates with dual redundant scheme, delta updates, container-based updates and combined strategies. Open source technologies such as Mender, RAUC and libostree-based solutions implement these strategies and provide tools to manage updates of multiple devices. Leon will discuss how to choose an appropriate open source solution to implement for a specific project.

Edge Computing with RISC-V and Linux

On Thursday, June 23 at 2:55pm CDT, Vitaly Vul and Maria Vul will present Edge Computing with RISC-V Platforms Running XIP Linux.

XIP stands for eXecute In Place, allowing code to be executed directly from flash without copying the code to RAM first, making it possible to run Linux on such RISC-V devices as Kendryte K210, which has only 8 MB of SRAM, not only for demonstration purposes but for real applications as well. This talk will cover running edge computing specifically on K210 under Linux with XIP enabled.

Part of Open Source Summit North America

These and many other excellent presentations at ELC are part of the Linux Foundation’s Open Source Summit. We hope you will join us in June.

At Yocto Project Summit: A/B Linux updates with RAUC

Konsulko Group Senior Software Engineer Leon Anavi will be speaking about A/B Linux updates with RAUC and meta-rauc-community: now and in the future at the Yocto Project Virtual Summit on December 1, 2021 at 12:20 (UTC).

About the presentation

RAUC is a safe and secure open source software solution for A/B updates of embedded Linux devices. It supports the Yocto Project and OpenEmbedded, Buildroot and PTXdist. Upgrades are performed through RAUC bundles which can be installed either through the network or the old-fashioned way with a USB stick.

In 2020, the layer meta-rauc-community was created to provide examples of how to integrate the lightweight update client RAUC on various machines. Leon will talk about the evolution of meta-rauc-community and provide guidelines for porting to new machines using Yocto and OpenEmbedded BSP layers.

About the Summit

The Yocto Project Summit is a 3-day virtual technical conference for engineers, open source technologists, students and academia in the OSS space. The classes will be presented in Zoom. It will be highly interactive, with chat sessions, side rooms, teaching assistants, and hands-on exercises with live class accounts. Registration is $40 for the entire conference.

Konsulko Group engineers to speak at ELC Seattle

Embedded Linux Conference, September 27- 30, 2021

Hyatt Regency Seattle | Seattle, Washington + Virtual

For over 15 years, Embedded Linux Conference (ELC) has been the premier, vendor-neutral technical conference for companies and developers using Linux in embedded products. Recent ELCs have expanded the scope to include both the user-space developers building applications on embedded Linux as well as the architects and developers working to deliver smart connected products and industrial IoT solutions.

At the upcoming Embedded Linux Conference, September 27- 30, 2021 at the Hyatt Regency Seattle (with a virtual option available), Konsulko Group engineers will give detailed technical talks on building RISC-V Linux systems, and Linux A/B upgrades.

Building a Low-key XIP-enabled RISC-V Linux System

Tuesday, September 28 • 4:00pm – 4:50pm

Principal Software Engineer (and GM Konsulko AB) Vitaly Vul (aka, Vitaly Wool) will discuss new hardware designs based on RISC-V, an open standard instruction set architecture. In modern times, RISC-V SoCs quite often have QSPI flash onboard which makes them perfect candidates to use XIP (eXecute In Place) technology to execute directly from flash without copying the code to RAM first. That allows to optimize memory footprint very tightly and thus opens up to really low-power IoT Linux appliances. Vitaly will present a demo how to run a mainline kernel configured for XIP on a RISC-V board, and discuss extending XIP support for RISC-V to 32-bit and MMU-less systems for low-key battery-powered RISC-V systems with RAM shortage.

Practical Experience with Linux A/B Upgrades

Wednesday, September 29 • 1:30pm – 2:20pm

Senior Software Engineer Leon Anavi will discuss deploying software upgrades to fleets of embedded Linux IoT devices, using A/B redundant systems with two identical partitions using popular open source solutions (like Mender or RAUC). Although they provide great features out of the box there are still plenty of technical obstacles to overcome for real-world use cases. In this presentation, we will walk through practical experiences using both Mender and RAUC with Yocto Project and OpenEmbedded. Leon will discuss BSP integration and porting efforts for new devices, bootloader requirements and configurations, tips and tricks for ARM and x86-64 systems, read-only file systems, partition layouts, storing persistent data during upgrades, managing single-file artifacts, simultaneous setup with Docker and other containers.

Join us in Seattle or virtually for this always informative, educational and fun conference for commercial and community embedded Linux developers.

“Surfing on an Interactive Kiosk” at Yocto Project Summit

The Yocto Project and OpenEmbedded are often used for building custom GNU/Linux distributions for powering interactive kiosk and displaying HTML5 content. Surf is a simple minimalist web browser based on WebKit2/GTK+ with interface that does not include any graphical control elements.

In his presentation, Surfing on a Interactive Kiosk, Konsulko Group’s Leon Anavi will describe the exact steps to build a minimal GNU/Linux distribution with systemd, X11, openbox window manager and the Surf web browser.

Yocto Project Virtual Summit, May 25-26, 2021, is both a workshop for engineers building customized Linux distributions and applications, and an open forum where maintainers, trainers and users present papers on how the project is evolving. The highly interactive classes will be presented in Zoom, with chat sessions, side rooms, teaching assistants, and hands-on exercises with live class accounts.
