After the release of the NXP MCU-Link debug probe, there have been hints in the Eclipse based MCUXpresso IDE that there must be another one coming. And indeed: another and more powerful debug probe is now available: the MCU-Link Pro. It is not only a debug probe but a power/energy measurement tool too, including an extra LPC804 mikrocontroller which can be used for all kind of things, like automation or scripting.
One of the most frustrating part developing embedded applications is if the debug connection fails somehow: with all the different factors like operating system, virtual machines, USB ports and hubs, debug probe and firmware a ‘connection failed’ is my nightmare. And this is probably the most frustrating parts for my students (and myself!)
The Teensy boards are great, but as they are they are not really useful for real development, as they lack proper SWD debugging. In “Modifying the Teensy 3.5 and 3.6 for ARM SWD Debugging” I have found a way to get SWD debugging working, at that time with Kinetis Design Studio and the Segger J-Link. This article is about how debug the Teensy with free MCUXpresso IDE and the $20 NXP LPC-Link2 debug probe:
