Updating an embedded system reliably can be challenging. Often the devices are in the field in places where troubleshooting is painful if something goes wrong. Methods for failed update recovery are therefore often built into these systems. One of the most common strategies is what’s known as A/B partitioning, where the system is overprovisioned and […]

Modern vehicles use driver monitoring systems (DMS) and occupant monitoring systems (OMS) to improve safety and comfort. They were also a big topic at the latest In Cabin event in Barcelona. Let’s take a closer look at DMS and OMS and how they create new uses for automotive data. What are DMS and OMS? […]

If you’ve run the SMB protocol, my name may be familiar. Every Microsoft document you read, every announcement you saw, every feature you configured in the past decade, all came from yours truly – Ned Pyle. For twelve years at Microsoft, I was the Principal Program Manager and owner of one of the most-used data […]

Open-source file systems offer benefits such as cost savings and flexibility, but they may not always be the optimal choice for different environments like Linux, commercial RTOS (Real-Time Operating Systems), FreeRTOS etc. Key factors such as performance, power fail-safety, support, and system architecture should be carefully evaluated. Let’s go through some of the potential risks […]
Automotive cyberattacks have been on the rise with the increased connectivity of our vehicles. Avoid recalls that are both financially costly and damaging to your company image with a simple solution. Use MACsec to secure the data in transit in your automotive network. There’s a reason today’s car manufacturers talk about “software-defined vehicles” (SDVs). Modern […]

NAND flash bit errors are detected (and corrected) as part of the reading process. File system metadata and frequently accessed files are read often, but the rest of the data might languish and slowly corrupt over time. Infrequent reads during idle time go a long way in preventing data corruption. Let’s say you own a […]
Designing an embedded system can be complex, with many factors to consider when selecting the right software and hardware components. In fact, embedded systems tend to be more complicated and expensive than most programmers think. In this article, we focus on one critical aspect of this complex process: choosing the right networking stack. While it’s […]
Over the past few weeks, there has been extensive commentary on the Volkswagen and Rivian joint venture. Unfortunately, many of these discussions remain superficial, lacking a thorough “under the hood” analysis. Given the potential significant impact on the entire automotive ecosystem, a more detailed examination might reveal some very interesting additional aspects. Personally I find […]

Floppy disks don’t have a partition table, hard drives do. What about SD cards? USB sticks? Raw NAND flash media? For that matter, what is a partition table? I aim to deliver an explanation and answer those questions, as well as offer some other angles on the topic, too. Along the way, we cover updates […]
