Almost 700 people registered for the first-ever Zephyr Developer Summit, which took place virtually on June 8-10, to learn more about the RTOS. We had 3 tracks, 5 mini-conferences, 28 sessions and 51 speakers who presented engaging technical content, best practices, use cases and more. We’ll be adding event videos each week to the Zephyr Youtube Channel. Stay tuned here for more videos.

Today, we’re featuring a few of the Safety presentations at Zephyr Developer Summit including the “Safety Mini-Conference” and “Quality vs Safety in ISO 26262.”

Conduct FMEA in the safety analysis of Zephyr – Enjia Mai, Intel 

Safety Analysis is one of the critical parts of Functional Safety Certification to ensure safety-critical functions and functional threats analyzed for correct behaviors per safety requirements. This video is to introduce Failure Mode Effect Analysis (FMEA), which is being applied to Zephyr OS safety analysis. FMEA is one of several effective software architecture safety analysis methods for examining different levels of software architecture to ensure the currently designed software architecture can cope with the threats of hardware and software issues. In the presentation, an example will be used to illustrate the 6-step process of FMEA implementations which include: ensure and define the scope/architecture and component analysis/identity potential failure mode/identity potential consequences/identity possible causes and add control measures/update documents and requirements. Last but not least, the impacts and challenges with FMEA analysis will be discussed in the presentation.

The Status of Zephyr with respect to MISRA Compliance – Roberto Bagnara, BUGSENG and University of Parma

In this presentation, we introduce the MISRA C coding standard and its role in the development of hight-integrity systems. We will then illustrate the findings of an independent assessment of Zephyr with respect to MISRA compliance. We will highlight some of the challenges that have to be faced in order to achieve MISRA compliance for projects based on Zephyr.  We will conclude with a gap analysis based on MISRA Compliance:2020, offering insight (and soliciting discussion) on possible courses of action to ensure Zephyr meets the language-subsetting requirements of users operating in safety-critical domains.

BOF: Path to safety certification for Zephyr – Amber Hibberd, Intel 


Quality vs Safety in ISO 26262 – Peter Bring, UL

This presentation looks at the different development stages described in ISO 26262 (the automotive safety standard) and resolves the underlying quality expectations for each and distinguishes those from the safety expectations.  As Zephyr works towards safety certifications and the formal capture of the requirements, these are important considerations to keep in mind as that process continues.

If you have questions or would like to chat with any of our Zephyr speakers, ambassadors or members of the Technical Steering Committee (TSC), please join us on the Zephyr Slack.
