Secure boot/ erase using NCS SDK v1.6.x

[Smart.Enrg]

Hi,

I am looking for example/ sample implementation of secure boot/ erase using NCS SDK v1.6.x,
suitable for nRF52833.

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

Thanks for your timely attention and help.

Hi,

Please refer to the Secure bootloader chain documentation. In essence, there is a B0 / immutable bootloader which is the first stage and that never changes. This establishes the root of trust, and validates and boots the next stage bootloader, which is MCUboot.
