I found an example that says this issue occurs because of linker script issue. Is that true ? How can I edit script file to fix this issue?

[Vidar Berg]

The linker script is, or at least should be, auto-generated by uvision. Seems more likely to me that it may be related to the issue discussed in the most recent issue Hellesvik linked to above.

Please open the nrf_section.h header in your project explorer and check if the blocks enclosed by __CC_ARM appear greyed out or not.

I checked this file, gray parts are enclosed in CC-ARM micro

Thanks. Can you try one of the BLE examples from the nRF5 SDK and see if you get the same result? Also, is this demo project you are testing publically available? I can take a look if it is.

yes， this is my project as enclosed。 you can take look at itble_app_templete.rar
