Please point me where I can see such code, or document/ resource that explains how I can do this.

In essence, there is a B0 / immutable bootloader which is the first stage and that never changes. This&nbsp;establishes the root of trust, and validates and boots the next stage bootloader, which is MCUboot.</p><div style="clear:both;"></div>
