Debug interface recommendations for Kinetis and LPC?

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!

Hi @richard37

Thank you for your post!

You may want to consider a SEGGER J-Link. It supports both Kinetis and LPC devices when used with MCUXpresso, and it is also natively supported by CodeWarrior 11.

This makes it a good alternative if you need a debug probe that can be used across both development environments and device families.
