Is there an driver example for the Edgelock Secure Subsystem (ELS) on the MCXN947?

ClarkS — Sat, 26 Jul 2025 16:52:37 GMT

I have searched the driver_examples in SDK_25_03_00 and do not find an example for using the ELS. Will one be available soon?

Hello @ClarkS ，

Thanks for your post. We already have the ELS demos in SDK, please refer to the attached picture.

I’m still not sure where these examples are located, but I’ll find them and probably learn about how your SDKs are organized in the process. Thank you!

Hello , you can find our SDK here: Select Board | MCUXpresso SDK Builder

Which IDE are you using? We support below Toolchain/IDE:

It's not clear to me how to configure the SDK Builder but based on my understanding of it, the ELS examples are apparently available for the MCUXpresso IDE and not for the VSCode Extension. Am I correct? Why is that?

Hello, @ClarkS

The SDK builder is where you can download the SDK. ELS examples also exist in the VSCode Extension.

I think I’m beginning to understand the SDK Builder. This time I picked so crypto related middleware, VSCode, macOS and got SDK_25.06.00_MCXN947

When we select several items in the filter, am I correct that it’s not building and sdk with only those items. Instead it’s only going to select a prebuilt SDK that has at least those items plus you get whatever more is in it. On the other hand I’ve seen if you select certain things, it may only offer an older SDK, but then it shows you what you could remove to get the newest SDK. Pretty nice.

I'm still confused on filtering on middleware vs examples. If I filter on ELS middleware only, the SDK will also probably contain examples. Correct?

Or if I filter on the ELS examples, it will certainly contain the middleware, and it will contain all the examples, even it it only lets me select one example. Correct?

it only lets me pick one ELS example but I assume that’s because when you select one you automatically get them all.

Is there any instructions on using the SDK Builder!

Thank you for your help!

Hello @ClarkS ,

Normally, when downloading the SDK, I will directly select all the middleware.
Of course, if you only need the ELS demo, you can also select only "ELS" in the middleware section.

Regarding the use of SDK Builder, the attachments in the following link may be helpful to you.
