S32K 148 Bus error

I debug flash driver, and get a exception. After that the Trace 32 shows bus error, and can't reprogramm.

How to recover it?

Does this happen during the Startup, during the run time of the application or during a flash operation?

I would recommend implementing the HardFault_Handler() in the project, and debug it as it is shown here:

What kind of bus fault is it?

If a precise fault, what is the content of the BFAR register?

Thanks,
