The problem: no source available at 0x0, when debugging on nRF52

[Mian]

Hi,

I'm a beginner. I downloaded nRF5 IoT SDK, and tried to run and debug the application "publisher" on nRF52 platform. And each time, I got a message "no source available at 0x0". And here is the picture:

Could anyone please tell me how to fix this problem?

Thanks a lot.
