Debug interface recommendations for Kinetis and LPC?

somaikoha — Mon, 18 May 2026 06:58:55 GMT

I do most of my development on the Kinetis series, and potentially some LPC parts in the near future. I've got a drawer full of debug interfaces from P&E Micro, including a Cyclone ACP that I use most.

I sometimes find myself switching from the $600 Cyclone to the $20 LPC-Link2 because the Cyclone has so many weird problems with MCUXpresso. Honestly the LPC-Link2 does most of what I need, it's just a bit slow.

Should I be looking at Segger interfaces? Can someone recommend a reliable, reasonably fast interface that's well-supported in MCUXpresso (and hopefully CodeWarrior 11 as well) that doesn't cause crashes all of the time, or fail to halt a running target? Trace support would be nice.

Thanks!

Hello @somaikoha ,

Thanks for your post. For MCUXpresso, the LPC-Link is actually a good option, it has excellent compatibility and is quite inexpensive. However, it doesn’t appear to be supported by CodeWarrior. For instance, CodeWarrior v11.1 only supports the debuggers listed below.

Eclipse IDE for Microcontrollerss | NXP Semiconductors

Given that, you might want to consider getting a Segger J-Link.

Hope it helps.
