WSL2 for Firmware Development

This guide provides instructions for setting up an environment for developing, debugging, and programming embedded systems firmware in the Windows Subsystem for Linux (WSL2).

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

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?

Updating NVIDIA Jetson devices with Memfault OTA

NVIDIA offers one of the most comprehensive SDKs for developers of AI-heavy products. It includes a development kit that can emulate other devices in the lineup (Jetson AGX Orin DK), a simpler development kit for “entry-level” products (Jetson Orin Nano DK), a ton of exciting software libraries, AI models and even more examples of how to use them. It’s truly outstanding and out of the box shows up as a Ubuntu workstation which will feel very familiar.

However, it can be a bit daunting to figure out how to take this workstation experience and turn it into a headless unit that you can ship to customers far away and update remotely.

Rust on Yocto: A Seamless Integration

At Memfault, our love affair with Rust began in late 2022. What drew us to Rust? Well, the typical allure of a modern programming language: an impressive type-system, memory safety without the constant jitters, efficient concurrency management, a thriving package ecosystem, and overwhelming support from our engineering team. To put it simply, we’re smitten. Our journey with Rust has been nothing short of transformative, enabling rapid progress and leading us to conquer challenges we previously deemed … non-trivial.

Emulating a Raspberry Pi in QEMU

This article dives into QEMU, a popular open-source emulator, and how to use it to emulate a Raspberry Pi on your desktop. At the end of the article, we will put the whole environment in Docker, so you will be able to emulate a Raspberry Pi by just using a Docker container.

OTA for Embedded Linux Devices: A practical introduction

A core belief of Memfault is that we can ship faster when we have good infrastructure in place. An essential piece of this infrastructure is tools to send firmware updates over the air. It enables the team to ship more often and spend more time building features.

In this article, we look specifically at what is required to ship over-the-air firmware updates for Linux systems.

Integrating Memfault into an Embedded Linux Project

In this blog post, I will demonstrate how to integrate Memfault’s offering on a Raspberry Pi 3B+ running embedded Linux.
