I found what's wrong. Fix it and example now works on our board.

What's wrong:

When I set BOARD_CUSTOM define and edit board_custom.h for set correct defines for struct NRF_CLOCK_LFCLKSRC to NRF_CLOCK_RF_SRC_SYNTH. The function sdh_state_observer_notify() from nrf_sdh.c for determine clock source used defines from sdk_config.h. When I set correct clock source as NRF_CLOCK_RF_SRC_SYNTH inside sdk_config.h the example build and run success. I removed duplicate defines NRF_CLOCK_LFCLKSRC from board_custom.h.

Have you enabled monitor mode debugging? The step-by-step debugging may stop the softdevice and cause problem; I'm not well versed in that area so search for "monitor mode debugging" in this forum to get more info. Also take a look at the monitor mode debugging in the JLink reference menu (should be in your JLink folder).

Other HW. Other Schematic. May be need more additionaly changes. I try found solution.

I use debugger for run step by step. After Init functions programm run in loop forever. Where called two functions. One for check state, second is power_manage(). First cycle call power_manage() with exit, second cycle call power_manage but never exit from function.

Is it the beacon example and the only changes are for the LF setting? What do you mean by "second call power_manage()" i.e. where does this "second" come from?

I'll do it my tomorrow. Thanks for your fast answer.
I forgot wrote my SDK version. This is nRF5_SDK_14.2.0_17b948a

Yes, nothing.

Our custom board programmed via nRF52 DK. And test Beacon works at the same time on nRF52 DK. Via nRF Connect I see only DK board, not my.

And you could not "see" (with BLE sniffer or nRFconnect app) your custom board advertising after power up?

Can you confirm that you are changing to NRF_CLOCK_LF_SRC_SYNTH in NRF_SDH_CLOCK_LF_SRC?

That is:

#define NRF_SDH_CLOCK_LF_SRC 2

If that is not the problem, can you try to use the RC oscillator and see whether that works (only for debugging)?

#define NRF_SDH_CLOCK_LF_SRC 0
