Explore Freedom of Choice with Debug Extensions for NXP and Cortex-Debug

I’m using different MCUS from NXP with VS Code, and for this I’m mostly using the NXP MCUXpresso extension for VS Code.

At the same time, I’m using the cortex-debug extension for other ARM Cortex-M based MCUs, for example the Raspberry Pi Pico series.

Does it makes sense to use cortex-debug for NXP devices, and what would be the benefit? More precise: can I use the NXP MCU-Link (LinkServer based) debug probes with cortex-debug, to debug another NXP MCU?

Using Tracealyzer for Embedded Systems Analysis

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.

Semihosting with LinkServer in VS Code

For an university research project, I need to write some console output and the same time write a file with data from the embedded board to the host. A logical choice for this is using semihosting.

Tutorial: Creating Self-Contained MCUXpresso SDK Projects

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.

Tutorial: Getting Started with MCUXpresso SDK – Tool Installation

The engineering and development landscape is constantly changing. This includes the embedded tooling and SDKs.

Back in the year 2017 I have used the version 2 (see Tutorial: Using Eclipse with NXP MCUXpresso SDK v2 and Processor Expert). Back then, it was Eclipse with make. Now we are in 2026 and things have changed to VS Code, cmake, ninja, python and west.

Luckily, although more and different tools are needed these days, the installation experience has improved significantly. It has shifted from installing multiple different tools to a streamlined installation process.

NXP LinkServer Now Supports ARM 64-bit for Enhanced Development

The latest release of the NXP LinkServer supports ARM 64bit (Debian) besides Windows, Linux and MacOS. With this, I can now develop on an NXP i.MX board. Plus, this enables an inexpensive way for automated on-target tests and CI/CD.

Navigating AI: Critical Thinking in the Age of LLMs

A few days ago, a reader of my blog sent me a message:

“Hi Erich, I am reading you since a lot of years. I think you are a pillar of my professional career. Thanks for this. Let me ask you now: what do you think about LLM and coding with LLM in embedded? My employer thinks it time to stop to hire people, because in 1/2 years everything will be substituted by AI. I am not on the same page. Are you using LLM for coding? What do you think about it? Thanks in advance.”

TL;DR: LLMs are changing and improving, making good engineering and education even more important. Studies show that AI can be useful, but productivity will not always increase. AI coding means more critical thinking and responsibility, not less. Engineering and education needs to adopt and change. This includes assessments and didactic, back to paper and defending the work. Learning how to learn is getting the critical skill in the age of AI.
