Secured Open Source Embedded Software

Publications

Lorient, France – September 13rd 2021 – IoT.bzh, an open source software company for embedded & secured solutions, today announced the release of its first redpesk® OS version called « Arz 1.0 ».
A ready-to-start full feature community edition is available online with its documentation.

« Thanks to redpesk®, customers can now focus on their differentiating applications relying on an easy-to-use CI/CD Long Term Supported platform (+10 years) with best of modern IT features adapted to embedded’s constraints » said Fulup Le Foll, IoT.bzh CEO.

redpesk® Arz 1.0 includes the following key features :

  • A new application framework AFB-V4 engine compatible with AGL-V3 up to 10 times faster
  • A new security model that can understand Smack but also an early access version for SELinux
  • +2 500 pre-built ready-to-use binary packages

But also many others as:

  • Cross-compilation for X86 & ARM architectures
  • SDK enabling fast native iteration cycles for developers
  • Automatic testing facility for both real & virtual environments
  • Extended QA through scanning tools
  • Release management solution
  • Reporting interface
  • Reference implementation for Over-the-Air updates
  • Core optional platform services (health monitoring, identity management etc)

All these features are supported on multiple SoC architectures and reference boards: Renesas H3/M3 ULCB, Raspberry PI 4, UP board & virtual machine QEMU-x86_64

The modern, connected, embedded Linux IoT device is facing a fundamental problem: the more connected it gets, the more cybersecurity threats it faces. Data link reliability, especially in the marine case, also makes it hard to efficiently push sensor data to the cloud.

This talk shows how to implement a reliable sensor data path from a marine IoT device running the redpesk embedded distribution to the cloud. It starts with lessons learned from real-world use cases: sending data from thousands of sensors to a cloud backend served by a choppy connection. It then dives into the IoT.bzh microservice framework, its security model (based on SMACK and SELinux) and how we coupled it with RedisTimeSeries.

Those, in addition to an OpenID Connect service, allows to securely and selectively funnel data from that target to the cloud. The talk concludes with a proposal on how this open infrastructure can be used by the community at large.

Modern SoCs contain heterogeneous processor devices that can be used to execute specific tasks. While Linux often runs on Cortex Ax processors, it is possible to run Zephyr on smaller cores like Cortex M or R. That way it's possible to isolate critical functions from a Linux rich environment. Applications can be found for safety use cases, power management purposes (wake up word, wake on sensor), or isolating realtime tasks. This talk is about solutions we found at IoT.bzh to make both world cooperate: How to communicate thanks to the RPMSG framework and how to start this remote processor from Linux using the remoteproc subsystem.

This talk has been given for Live Embedded event 2021.

Modern SoCs contain heterogeneous processor devices that can be used to execute specific tasks. Renesas R-Car Gen 3 embeds a Cortex-R7 that can access any memory mapped devices.

Taking advantage of this processor allows to have critical applications that should bring the proof of their robustness (realtime, safety, power consumption..).

This talk start with a presentation about technical constraints about having a MCU running RTOS.

This talk also gives an introduction on how to manage this processor lifecycle from Linux side and how to communicate between both worlds (AGL and Zephyr).

This talk was presented at the AGL All Member Virtual Meeting 2021.
