You can change the memory layout by adjusting linker settings. Exactly how you do that depends on the toolchain you use, see this blog post for more details: https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/adjustment-of-ram-and-flash-memory

How is he going to change the memory layout in example boot loader code?

Hi,

I think you should be OK with RAM. the bootloader runs as a standalone BLE application so it does not share RAM with the main app. However, we allocate 32K with flash by default requiring either the app or bootloader to be shrunk a bit. Also, you need to consider if you need to store app data (required if you support BLE bonding - min. 2 Flash pages).

Default bootloader memory layout: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_bootloader.html?cp=7_1_3_5_0_7#lib_bootloader_memory
