COrtex-M7 (IMXRT1171) crash

[Nexus76]

Hi, we have a strange behaviour with the firmware that running in SDRAM, so to understand what's the problem we made a firmware that running also on

i.MX RT1170 Evaluation Kit
MIMXRT1170-EVKB
the problem is that randomly the firmware goes to crash, in detail the micro reset it self, so we don't have any information by trace32, but if with the same firmware if I turn ON the M4 clock (I remebere the micro is IMXRT1171 without M4 ) the crash doesn't happen.

So the question is, there is a valid reason because M4 clock make a difference ?

Best regards
