Hi,

This is a very vague question. You haven't mentioned whether this is seen with bootloader (SBL vs SPL) or seen when you are running an application, or on what board this is?

Is this part of a board bringup?

Thanks.

Hi,

This is seen when running an application.

I'm doing a read and write stress test for MT35XU512ABA1. Write and read 256 bytes every 5 ms.

This problem often occurs, causing the program to crash and cannot be debugged.

Every time it crashes, the register value is as shown in the picture.

Thanks.
