nRf5 Taiyo Yuden configuration with Segger and j-lin

[FrankX2138]

I have a Taiyo Yuden Evaluation board , with EBSHJNZXZ completed with Segger and j - link , when load the project in board, not have any error debug, the sketch is load successfully  , but when connect with iPhone device in nRF Toolbox is impossible scanner board , is always  invisible . This happens with any example of softdevice

where am I wrong? How can I solve the problem

Hi!

Are you sure that your board is advertising?

Did you remember to flash the softdevice to your board?

Best regards.

I'm new to nrf52 and segger j-link, but of course I flashed the project on the board.
I think the problem is in the setting at 32Khz,

the solution proposed in (

https://github.com/TaiyoYudenUSA/Bluetooth-5-Throughput-Demo

) not work

the solution proposed in manual tail yodel not work

Important notes

32kHz Clock

This module does not installed 32.768kHz crystal. In case of operating without external crystal, please use following example code in order to enable internal 32.768kHz RC oscillator (32k RCOSC).

nrf_clock_lf_cfg_t clock_lf_cfg;
clock_lf_cfg.rc_ctiv = 16;
clock_lf_cfg.rc_temp_ctiv = 2;
clock_lf_cfg.source = NRF_CLOCK_LF_SRC_RC;
clock_lf_cfg.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_250_PPM; SOFTDEVICE_HANDLER_APPSH_INIT(&clock_lf_cfg, true);

)

there are errors, much probalie due to software update by softdevice
