Why did I cause S32K144 to die when I sent the command to FS6500's WD_ANSWER register via S32K144?

Why did I cause S32K144 to die when I sent the command to FS6500's WD_ANSWER register via S32K144?
This will not happen when I am sending instructions to other registers in FS6500.

Here's my code：

      DataSend[0] = 0x4D;
      DataSend[1] = 0xD3;
      master_state = LPSPI_DRV_MasterTransferBlocking(SEND, &DataSend[0], &masterDataReceive[0], BUFFER_SIZE, 1000);

Why does this happen?

Hi Jason,

Could you please post here your complete start-up SPI sequence? Have you tried using our recommended initialization sequence shown below?

Best regards,

Tomas
