FreeRTOS 11 introduced symmetric multi-processing (SMP) support in the mainline kernel, meaning a single FreeRTOS kernel is managing multiple processor cores. This allows for high performance but also makes the runtime system more complex, meaning higher risk of issues and more difficult debugging. System tracing with Percepio Tracealyzer can offer an effective remedy by providing insight into the system execution.

While using a full-blown filesystem for storing your data in non-volatile memory is common practice, those filesystems are often too big, not to mention annoying to use, for the things I want to do. My solution? I’ve been hard at work creating the sequential-storage crate. In this blog post I’d like to go over what it is, why I created it and what it does.

IoT device management refers to processes or practices used to deploy, monitor and maintain IoT devices. As organizations scale up their IoT efforts, a solid device management approach is essential to running a secure, streamlined fleet of devices. The proliferation of connected devices worldwide (projected to reach 18.8 billion in 2024) means that IoT device management is growing more complex, a reality that has not gone unnoticed by bad actors.

Internet of Things (IoT) devices are everywhere you look. From the smartwatch on your wrist to the security cameras protecting your offices, connected IoT devices transmit all kinds of data. However, these compact devices are different from the other technologies your organization uses. Unlike traditional devices, IoT devices lack a standardized set of security capabilities, making them easier for attackers to exploit.

There have been significant improvements in Tracealyzer over the last years. If you haven’t tried it in a while—or if you’re just getting started—here are some tips and tricks that can be handy when analyzing your FreeRTOS applications. As you may know, the TraceRecorder library automatically records task scheduling and FreeRTOS API calls using the standard trace hooks in the FreeRTOS kernel.

In this very Memfault-centric post, I’ll be talking about how we shipped our SDK as an ESP-IDF component. This is a continuation of our efforts to make it easier to integrate Memfault into your projects, specifically targeting ESP32-based projects.

You hear us at Percepio talking about Observability a lot. For customers using our award-winning Tracealyzer tool, this might sound a bit strange – isn’t Tracealyzer about diagnostics, debugging and profiling? Mostly, yes, but let me share why we are putting so much emphasis on our Continuous Observability solutions.

Last week, a handful of Memfolks had the opportunity to travel to Austin to attend the first ever Embedded World North America1! Embedded World NA welcomed 3,500 visitors and 180 vendors across 3 days2. While it was surely a smaller showing than Nueremburg’s Embedded World, we still wanted to quickly touch on our takeaways from the event. In this post, we will cover what we learned from the first Embedded World North America.

Many companies that provide IoT or device management solutions need help building an in-house monitoring solution. Managing devices for your clients is challenging enough—building a monitoring system is not everyone's wheelhouse and takes time to set up. In this article, we will review some of the most common use cases for device management companies and discuss how these businesses can use MetricFire to save time and money on their monitoring.
