nRF54L15 - Secure boot implementation

[sravan.rikka]

Hi Team,

We have started our BLE development using nRF54L15 using SDK 3.1.0.

We have selected this MCU because it support all security features, we are going to start secure boot implementation.

Can you please provide detailed steps how to enable/implement the secure boot innRF54L15?

And any sample code is available, please share the path in which folder it is available in SDK 3.1.0, we will start development using sample code.

Regards,
