In my latest research project I’m using the NXP FRDM-MCXN947 board. As part of that project I have to collect and export application trace data for later analysis. In that project I’m using the the Tracealyzer product from Percepio.
In this article I describe different ways to export trace data from the embedded target: using generic GDB commands or with an trace exporter in VS Code.

For an university research project we are implementing a software simulator for the EZH (or SmartDMA) co-prozessor present on some NXP MCUs.
This article describes how to setup and build QEMU in a docker container, including debugging QEMU with VS Code.
Continue reading →Debugging a C/C++ application inside a Docker Container using VS Code is surprisingly easy.
This article shows the needed steps.
Continue reading →With the NXP MCU-Link Pro I can measure current and power/energy of an embedded target. In this article I describe how I can use and visualize that data in VS Code:
From my previous MetaClockClock project, I still had some hardware available. So I decided to build my largest build so far: to clocks with 78 clocks each.
In Tutorial: Getting Started with MCUXpresso SDK – Repositories with VS Code and Tutorial: Getting Started with MCUXpresso SDK – west I showed how to get the MCUXpresso SDK. In this article it is about tweaking and streamlining the project.
The result is a clean, portable and self-contained MCUXpresso SDK project.
Recently I have been asked “How can I debug a Linux application with VS Code?”. I’m covering that topic in my ‘Embedded Application Development Course on Linux”.
I realized, that I have never covered that topic in any of my blog articles. So here we go: I show how easy it is to use VS Code to debug a Linux application. You can use this for example with an Raspberry Pi. Or for example the NXP i.MX93 which I’m using in this article.
Continue reading →In “Tutorial: Getting Started with MCUXpresso SDK – west“, I demonstrated the ‘west’ tool’s usage. It helps in acquiring an SDK repository. Instead using the command line tool, I can use the NXP VS Code extension to do the same.
In my earlier tutorial I showed how to install the necessary SDK tools. In this article I’m going to install the SDK sources. For this I’m going to use west. This is a command-line ‘meta-repository’ tool.
