Dear Senlent,

Thank you for your reply.

At the time of emulator access [PE microlink] Is it possible to add access rights with a security code?

PE microink editor [codewarrior] feature to add security key, which will compare with MCU key. if those keys match then access will be granted.

please let me know if the above scenario can be possible?

Thanks,

Pratyay

I haven't tried your usage, I'm not familiar with these tools, maybe you can try it, but it will probably make your chip permanently encrypted.

I think it should not be possible(not very sure)，you can take a look at the AN4507 to know more

Using Kinetis Security and Flash Protection Features:

BR!
