Sequential-storage － Efficiently Store Data in Flash

14 Nov 2024 by Dion Dokter

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.

Publishing the Memfault SDK as an ESP-IDF Component

24 Oct 2024 by Noah Pendleton

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.

Comparing Firmware Development Environments — Linux, Windows, WSL2, and VMWare

10 Oct 2024 by JP Hutchins

About a year and a half ago, I decided to take a different approach to setting up a Zephyr environment for a new project at Intercreate. Instead of using my trusty VMWare Workstation Linux VM, I opted for WSL2. I was curious to find out: Would hardware pass-through for debugging work reliably? Would all of the tooling dependencies be supported? What about build system performance?

How Memory Usage Patterns Can Derail Real-time Performance

29 Aug 2024 by Bert Schiettecatte

In this article, we will learn how memory usage patterns can affect the real-time performance of an embedded application, drawing from a recent experience tracing an audio DSP application running on an embedded Linux platform. First, I will introduce the product in question and the real-time audio software I developed for it. Then, I’ll describe the issues I encountered with audio callbacks and the strategy I followed to determine the cause of the issues, ending with my solution and lessons learned.
