hello ,

some brief about my board it is nrf ble nrf52810 without crystal. 

i am using segger debugger.

while doing step by step execution it come till line sd_softdevice_enable (line number 214) and it get stuck

You can't enable BLE (softdevice) without a crystal it is required for timing.

Hi there,

The HFXO 32MHz crystal is required, but the LFXO 32 kHz crystal is optional.

Which crystal do you not have?

If you don't have the LFXO crystal, then you need to configure your project to use the internal RC oscillator instead.

i am using RC oscillator with below configuration 

#define NRF_SDH_CLOCK_LF_SRC 1
#define NRF_SDH_CLOCK_LF_RC_CTIV 0
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 0
#define NRF_SDH_CLOCK_LF_ACCURACY 7

Hi,

NRF_SDH_CLOCK_LF_SRC should be 0 to use internal RC oscillator.
