IMX9352:M33 Core SCB->BFSR:IBUSERR fault: Instruction bus error on an instruction prefetch

[mdxy_2010]

Hi, Vendor

We are run  trustzone_examples on IMX9352 M33 core, But we get the following error:

Hello from secure world!
Entering normal world.
NON_SECURE_START: 0x0fff0000
TZM_JumpToNormalWorld:37 run here
TZM_JumpToNormalWorld:73 run here

Entering HardFault interrupt!
SCB->BFSR:IBUSERR fault: Instruction bus error on an instruction prefetch.
TRDC MBC slavemem:1 Violent access
domainId : 0
Address : 0x00000000
Error state : 0
Error attribute : 0
Error type : 0
Error port : 0

From above log, the program had run normal world code,but get Instruction bus error on an instruction prefetch：

It maybe the NON_SECURE_START memory region security config error? 

Can somebody give me some debug suggestion？

thanks a lot！

Demo program for trustzone_examples tested without issue. Please double check the procedures about how you have built the example, there are readme in these examples.
