The latest NXP MCUXpresso VS Code extension and LinkServer software included a small but very helpful feature for me: the ability to identify a connected probe with a blinky:

NXP LinkServer Adds Standalone Power & Energy Measurement
NXP has released a new LinkServer v26.9.130. And it comes with a major new feature: it now includes power and energy measurement:
Additionally, it has a command line interface for this, making it ideal for AI agent usage or for automated tests in a CI/CD environment.

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?
Debug C/C++ Apps in Docker with VS Code: A Step-by-Step Guide
Debugging a C/C++ application inside a Docker Container using VS Code is surprisingly easy.
This article shows the needed steps.

I’m getting my head more and more around CMake and its features. After having so many issues with VS Code dealing with CMake Kits, I have found feature in CMake which really is a game changer for me: CMake Presets.
New SEGGER J-Link-OB LPC4322-based Firmware with Target Power
Sometimes I have a wish. Not every time it gets fulfilled. But this time I’m lucky and happy developer. A few days ago I wrote about the LPC4322-based SEGGER OB (on-board) J-Link firmware. It works great, but the board requires another USB cable to power the target board.
Rolf Segger contacted me, and a few days later I had a J-Link firmware with a ‘power-on’ feature:
That way, only one USB cable is needed. All what you need to do is to update the firmware.

One major concern of embedded system development is performance. Microcontroller have more MHz than in the past, but embedded applications are all about timing and real-time aspects.
The challenge is: how to get data off the target in realtime? SWO can help with this….

If a Cortex microcontroller is unresponsive to a debug connection for various reasons, then this trick might help to recover that device for you. All you need is a debug probe from PEMICRO and a utility.
OpenOCD with MCU-Link
The NXP MCU-Link is a powerful $10 debug probe for ARM Cortex-M devices and works with the NXP LinkServer for debugging. The LinkServer does not an implement a gdb server, so it limits its usage e.g. for scripting or command line debugging. But as MCU-Link is also a CMSIS-DAP compatible debug probe, I can use it with OpenOCD which is open source and implements a GDB server. This article shows how I can use it with the MCU-Link.

Debugging Bootloader and Application with one Debug Session
If having a boot loader running on a micro-controller, it is very useful if both the boot loader and the loaded application can be debugged together:
