Hello,

[quote user=""]From where these files partitions.yml file and pm.config are getting the relevant addresses, offsets and size of mcuboot and app?[/quote]

From Partition Manager, which processes .dts files, CMake scripts, and optionally pm_static.yml. Since you are working with peripheral_lbs sample pm_static.yml is not present and partition manager determines the layout dynamically. Check https://github.com/nrfconnect/sdk-nrf/blob/v2.7-branch/cmake/partition_manager.cmake and https://github.com/nrfconnect/sdk-nrf/tree/v2.7-branch/subsys/partition_manager, see the device tree files which contains the flash memory definitions.

[quote user=""] I want to have and understanding of this process. The purpose is to know how to flash bootloader and app separately on relevant addresses.[/quote]

If you check the generated build/partition you could see that the bootloader (MCUBoot) and application have separate memory regions, you can flash them independently. MCUBoot starts at 0x00000 and occupies 0xC000, and the application starts at 0x0C200 and occupies 0x38E00.

[quote user=""]Where can I find documentation or literature explaining how to define and use macros in pm_static.yml for configuring flash partitions?[/quote]

See the section "Partition Manager" in the technical documentation. There, you can also find the section on configuring static partitions.

Kind Regards,

Abhijith
