Hello,
I am learning to create library in segger. I am using segger example https://wiki.segger.com/How_to_create_a_library_project_and_use_it_in_executable_project
I have created a small library project in the blinky sdk example. SDK version 15.2. Using that project .a file created. The same file was included in the blinky example. made the function extern in the main.c. Tried compiling the project I received below error of VFC.
Building ‘blinky_pca10040_s132’ from solution ‘blinky_pca10040_s132’ in configuration ‘Debug’

Is my way of adding library file is correct? do I need to make some changes in linker? if so kindly suggests how?
