MCUXpresso IDE V11.3.0 for 2021

I’m in the middle of the university exam season: means writing exams and do grading. The same time the new semester is approaching too and I need to prepare the new course material. For the classes using NXP parts I’m using the Eclipse based MCUXpresso IDE, and I just received the announcement that a new version V11.3.0 is available: time to check out what is new.

Eclipse Indexer Debug Tips

Eclipse includes a background parser called ‘Indexer’ which is used to assist the developer with various kind of information, for example jumping to a variable declaration or definition. Basically it is a parser running in the background collecting information about the sources and building up that ‘index’ data base.

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.

Configure hidden and internal Shortcuts in Eclipse

A very useful feature in Eclipse is Ctrl+Shift+L which lists all the available shortcuts:

Pressing Ctrl+Shift-L again will open up a dialog where I can configure them. But what if the shortcut or action is not listed there?

Getting Started with Microsoft Azure RTOS (aka ThreadX)

If you are a regular reader of my articles, you probably know that I’m using FreeRTOS in most of my applications, for obvious reasons. But clearly this is not the only RTOS out there. After Microsoft had acquired Express Logic back in April 2019 things kept quite for a while. To me the crown jewel of Express Logic is the ThreadX RTOS. But recently Microsoft is pushing more and more the ‘Azure Sphere’ and trying to monetize the ‘IoT’ (I apologize for mentioning that overused acronym) application space and providing it now free for devices from selected partners which includes NXP now.

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:

Power Measurement with the PEmicro Multilink Universal in Eclipse

Implementing low power in embedded applications implemented can be challenging. Measuring current consumption is a first step to see if the software changes indeed have an effect on the current consumed. The PEmicro Universal Multilink FX debug probe comes with a useful feature to provide power to the target and the same time to measure the current consumption and to show the current used in the Eclipse IDE:

Tweaking MCUXpresso IDE Black Theme

‘Dark’ or ‘Black’ themes are on vogue: some love it, some do not care. The good thing is that we all have a choice. Things are getting improved on the host OS (Windows/Linux) side, but the challenge is still on the application side, but things are getting better. This is true for the Eclipse based IDEs too, with the NXP MCUXpresso IDE V11.2.1 just recently released: it comes with improved Dark Theme support:
