How to KV10Z Enable Security

zhitailiu — Thu, 23 Mar 2017 01:52:31 GMT

Hi,

Sorry for asking, first time using freescale/NXP products.

I know that FSEC [SEC] bits controls the security,

How shall I write it?

Is there an example code?

Something like declaring a constant array in that address?

Please tell me,

Thanks for reading!

Hi Zhitai Liu,

Thank you for your interest in NXP Kinetis product, I would like to provide service for you.

From the KV10Z reference manual, you can get that the FSEC is in the flash address 0x40c.

The FSEC bit meaning can be found in the register:

If you want to change the SEC bits, you can modify it in your code project.

Now, take MDK project as an example:

Change the FSEC is OK.

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Kerry
