Hi     

I am using the demo of S32k144 about backdoor, but I found that the address 0x40c in the SREC file I generated was 0xBF, but it changed to 0xBE after burning to MCU, the MCU I used was S32K118, the demo content has been transplanted, but it does not seem to be unlocked. It has been unsecure. Can you provide some support?

In winidea, you need to configure the following two things to modify the security zone correctly. However, the security zone may be permanently locked after modification.
