Yeah. Custom boards usually don't have external crystal, so we need to use the internal clock with the setup you posted above. Happy to help ☺

It's working now!

The key point was:

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_SYNTH, \
.rc_ctiv = 0, \
.rc_temp_ctiv = 0, \
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

Now I have my custom board advertising.

Thank you, Tai, for your help,

David.
