RE: v3.4.0 samples, specifically MCUboot+sysbuild+ns-variant+dts-style partitioning example

Thank you.

Do you think it would also be possible to get a sample that uses NSIB as immutable bootloader and MCUBoot as upgradable bootloader? According to recommended secure setup.

Also, will this/these samples be included in an upcoming SDK release?

Hello,

I put together a sample based on the peripheral_lbs sample with the configurations you requested, as there aren't currently any DFU samples in the SDK that support the NS variant. Please see attached. Notice the memory_map.dtsi file in the project root, which I included in the mcuboot and application's DT overlays to override the default partition layout. Also, this sample has not been thoroughly tested or reviewed by others, but I did some basic testing on my desk to verify that DFU and the PSA Crypto support required for Bluetooth pairing worked.
