No, I misunderstood it. I've changed the nrf_bootloader.c file and now I can able to debug.

Thank you.

No, not in your application. It is part of the bootloader.

Just to check: you are using the nRF5 SDK secure bootloader, right? Or did I misunderstand? If I misunderstood this, then perhaps you can elaborate a bit more, and start from the beginning?

Hi Einar,

nrf_bootloader.c file is not included in my application. Do I need to add it to my application?

Hi,

The nRF5 SDK bootloader will do a CRC check of the application, and only start it if the application is valid. So in order to make the application start (also when debugging) you need to generate and flash a valid bootloader settings page. That quickly becomes tedious during development, so I suggest you slightly modify the bootloader while developing, so that app_is_valid() in components\libraries\bootloader\nrf_bootloader.c always returns true. That way the bootloader will start the app regardless of the content of the bootloader settings page. And with that, you can program and debug the application from Segger Embedded Studio without any problems.
