Debug issue with SPU5746C MCU 176 pin

Hello NXP.

I have used a demo board to develop an application in MPU5746C-256 Pin MCU and I can successfuly debug my application.

Then I have ported my application project from 256 pin to 176 pin MCU and trying to debug it. But, I am not able to debug the application. It is haling at address "00000010:   se_illegal" and running  se_illegal instruction.

I have read the memory region of my application and it has loaded into the flash memory.

I need your help to sort this problem. I am sharing the logs which I have got from Console window.

Hi,

Are you able to figure out which line of code is causing application to jump at 0x0000_0010? There is probably an IVOR exception occured during code execution?

Are you able to reach main() function? If not then I'd recommend you to disable run on reset feature and check if startup code is executed correctly:

If the very first instruction causes the IVOR exception please check if MCU Reset Configuration Half Word + reset vector is correct and check ABS/FAB pins so the internel flash boot mode is enabled.

If it does not help could you send us more information e.g.:

The debugger screenshots that depict the error.

Describe the circumstances before the error occurs.

Are you using a custom board or NXP evaluation board?

This will help us to resolve this iisue much faster

Thanks!

Stan
