Why can the CGMS routines of nRF connect SDK run on the development board, but not on the circuit board designed by myself, even though the chips of both are exactly the same?

I'm still a beginner，I don't understand why the board I designed can't run the nRF connect SDK application, but the nRF5 SDK 17 application can run normally. I want to know what the difference is between the two? What kind of settings do I need to make? It's interesting that the development board can run these applications
