MCUXpresso debug session seems to 'timeout' if not started quickly

I've noticed that when I start a debug session, and it gets to main() and pauses as normal, if I don't start the run within a certain time frame, it seems to crash and I get this call stack:

McuEmbedWhiteChip JLink Release [GDB SEGGER Interface Debugging]	
		Thread #1 57005 (Suspended : Signal : SIGTRAP:Trace/breakpoint trap)	
	arm-none-eabi-gdb (	


I haven't timed this, but it seems to be within a minute or two.

Any ideas please?


  • Target RT1021
  • Debugger SEGGER J-Link Pro - with latest software/firmware
  • MCUXpresso IDE v11.8.1 [Build 1197] [2023-10-27]
  • Windows 11

Kind regards.

Thank you for contacting NXP support.

I appreciate the information, but before continuing the support can you please help me by updating the MCUXpresso version 11.9.0. Also if it is possible can you please help me y telling me if you are running an specific SDK or if this event happens on general.

In case this is a custom project please help me by testing with a hello_word example just to have another point to start.
