RT1176 cm7 rogram received signal SIGHUP, Hangup.

I'm debugging on a custom RT1176 board.
Debugging the SDK sample 'evkbmimxrt1170_iled_blinky_cm4' works without problems.
However, when I try to debug the SDK sample 'evkbmimxrt1170_iled_blinky_cm7',
the following message appears and it fails to run correctly:
------------------------------------------------------------
Program received signal SIGHUP, Hangup.
0x00254330 in ?? ()
warning: Could not fetch required XPSR content. Further unwinding is impossible.
------------------------------------------------------------
What is the difference between cm4 and cm7 that makes it work or not?
Any advice would be greatly appreciated.
