Demo of Flash security control for KV30

jimmyli — Mon, 13 Jan 2025 09:38:49 GMT

Hi NXP,

We have plan to control the security status of flash in KV30 by backdoor key technology, and have read the document AN4507 <Using the Kinetis Security and Flash Protection Features.pdf>.

Do you have some software DEMOs about backdoor key to enable or disable KV30 flash protection ?

Thanks very much.

Hello @jimmyli ,

Thanks for your post. Please refer to the below post:

How correct use of Backdoor Key in FRDM-KL82Z board - NXP Community

The KL82Z and KV30 are the same when it comes to controlling the flash security status. You can directly refer to this. If you encounter any problems, feel free to ask further questions.

BRs,

Celeste
