actually i have experience in BMD300(based on nrf52832)...on that both LFCLK RC oscillator and external LFCLK crystal oscillator works...first time here i tried with LFCLK Synthesized from HFCLK(NRF_CLOCK_LF_SRC_SYNTH)...
Have you set the correct PPM for your LFCLK crystal ? Could you double check that the crystal on your board is mounted correctly, i.e. not shifted by 90 degrees for example? Did you check if the crystal is within the specification? And double checked the value of the two capacitors?
Thanks for your suggestion , i resolder both nrf52 and crystals, now its working on both clock source NRF_CLOCK_LF_SRC_RC and NRF_CLOCK_LF_SRC_XTAL. But till now some phones like iphone 5s where not responding with my device...whether it depends on ppm / pcb antenna ???...these phones working fine with nrf52 dk and bmd300..
You are not able to find your device using e.g. nRF-Connect?
NOW IT'S WORKING .....THANKS FOR YOUR RESPONSE...YES IT'S SHOWS IN nRF-Connect....i thinks problem is in soldering issue..
