At 11:30 – 12 pm, Prof. Robert Oshana with NXP Semiconductors, will give a presentation titled, “Practical Software Testing Techniques and Guidelines for Embedded Systems.” Embedded technology has revolutionized sectors of the industry in ways that were previously never thought possible. For this reason, product testing is becoming increasingly important. Ensuring that our embedded technology functions properly is a priority for most companies, regardless of where that technology happens to be located. In this presentation we will explore white box and black box techniques for testing embedded systems, talk about system and performance testing, and summarize some of the unique testing requirements and approaches for real-time embedded systems. Topics include static and dynamic analysis techniques, exploratory testing, equivalence partitioning and boundary value analysis, and hueristics based testing methods.

At 12:30-1 pm, Kate Stewart with the Linux Foundation will give a presentation titled, “Safety Certification and Open Source – Can They Work Together?” 

The last 20 years have seen a tremendous surge of new technologies and capabilities emerge from open source software. These open source building blocks have become increasingly attractive as the base for innovative new products. Safety critical applications are now using them as well, but we lack infrastructure to assess when this software is safe to use, that can keep up with the rate of change of open source development. Her talk will look at some of the challenges and approaches to building trust and confidence in open source used in safety critical software coming to new products. The approaches taken by 3 open source projects (Linux, Xen, Zephyr) will be discussed and contrasted.

At 12:30-1 pm, Pal Kastnes with Nordic Semiconductor, will give a presentation titled, “Bluetooth Security – A Technical Overview & Implementation Guide for Embedded Developers.” The Bluetooth specifications enable advanced security features to accommodate a wide variety of embedded applications and systems. This session will provide implementation guidelines to help embedded developers understand the range of security options available when developing with Bluetooth, as well as some best practices to follow when securing Bluetooth devices and solutions.

At 4-4:30 pm, Martin Woolley with Bluetooth SIG will give a presentation titled, “Bluetooth Location Services and High Accuracy Direction Finding.”Bluetooth can be used for many types of location service and it’s an area forecast to experience the biggest growth in the next few years, with 431 million location related devices shipping in 2023. In 2019, Bluetooth acquired a new capability which allows the direction of a signal to be accurately determined using one of two methods known as Angle of Arrival (AoA) or Angle of Departure (AoD). Come to this session and hear about this Bluetooth location services and the new direction finding feature, how it works and the uses it’s likely to be put to.

At 4-4:30 pm, Prof. Robert Oshana with NXP Semiconductors, will give a presentation titled, ” Guidelines, Tips and Tricks for Managing Open Source Software for Embedded Systems.” Open source software is ubiquitous in embedded computing. Whether you are using the Linux or Zephyr operating system, open source machine learning components, or any other form of community based software, its important to understand the basic guidelines and principles for developing and managing open source software. This presentation will use multiple actual industry examples to demonstrate practical tips and tricks for open source software development. Topics include developing an open source policy, understanding the basics of licensing open source software, how to update promptly, using a binary repo manager, how to particpate in the community and upstream software, how to use the proper build tools, tips for how and when to fork, and other practical examples. With the right framework and understanding, open source development for embedded systems can be more efficient, and less risky and error prone for the developer and the organization.
