Linker error - Segger embedded studio

[Niranjan Pandian]

I am getting the following errors.

Building ‘1’ from solution ‘1’ in configuration ‘Debug’
Generating linker script ‘1.ld’
Linking 1.elf
Output/1 Debug/Obj/ses_nRF_Startup.o: In function `InitializeUserMemorySections':
undefined reference to `__start_nrf_sections'
undefined reference to `__start_nrf_sections_run'
undefined reference to `__end_nrf_sections_run'
Build failed

I can find the references in - "ses_nRF_Startup.s" file. but couldnt find the declarations. 

Can someone help?

Hi,

It is probably that you have forgotten to include the path. Click on your project in the project explorer on the left. Then select Project(Tab on top) -> Edit Options -> Select Preprocessor tab(Remember to change the box on top from "Debug" to "Common"). Add the path of the file to User Include Directories field to include the device header files.

Have a look at the tutorial.

Thank you. But I have added the path of all the need libraries and drivers. In fact, I removed the Preprocessor directive "Initializeusersections" from the Edit options, The program works fine.

Can you suggest which file has the reference's mentioned?

None of them have the references mentioned, the post you've replied to has completely misunderstood the question. You need to read the post I pointed you to plus the post it links to. You need to set the sections up in the flash_placement.xml file and some other places.
