When experiencing a hardfault when debugging with LPCXpresso, looking at vectpc would give you useful hints on what had happened. Screenshot below is from a hardfault in LPCXpresso

In MCUXpresso this information does not apare:

How do I find the same information in MCUXpresso?

We'll be implementing a fix for issue with the (LinkServer-specific) "vectpc" functionality in the next IDE release.

In the meantime, and also if you try using a different probe type, then this blog article may be of interest...

Debugging ARM Cortex-M Hard Faults with GDB Custom Command | MCU on Eclipse 

Basically this mimics exactly what the IDE is doing with "vectpc".

Any luck in finding the problem? Additional information would be very helpful in hardfault tracking, and moving whole project to legacy IDE does not seem reasonable....
