What can cause a S32K board to lock up

Hi

Since the development of S32K146 chip, it often leads to chip lock up. We have been familiar with some operations, but there will still be accidents. I would like to ask what circumstances or some misoperations will lead to chip lock up?

The known case is as follows:

  • Modify the content of the address 0x400-0x40F

  • Burn write power off, if in the Debug time carelessly caused the chip power off

In order to avoid the chip lock, I want to know if there are other operations that will cause the chip lock? And what should we do if we encounter the chip lock problem?

Thanks
