case about nRF5340 memory layout

Hello, 

Could you please elaborate on what exactly you are looking for? 

Have a look at the memory chapter from Network Core and memory chapter from Application Core in the nRF5340. 
Edit: Also, there is a chapter in the Product Overview

Kind regards,

Hi Øyvind,

1. In nRF52 series chips, user available Flash and RAM need to deduct MBR Soft Device and bootloader

2. In nRF5340, how much space and RAM are occupied by MBR Bootloader and SoftDevice?

Thank you for all your assistance.
Kind regards,

This was the case for the nRF52 series, where i.e. the SoftDevice had a static flash/RAM usage. 

In the nRF Connect SDK (NCS), which must be used for the nRF5340, this is not the case. In NCS the flash and RAM usage are more variable. When building an NCS project, you will see the flash and RAM usage at the end of the build e.g.

Memory region         Used Size  Region Size  %age Used
           FLASH:      116756 B         1 MB     11.13%
            SRAM:       32306 B       448 KB      7.04%
        IDT_LIST:          0 GB         2 KB      0.00%
