sd_softdevice_enable loop

[Fabien Comte]

Hello,

I have a program that do an infinite loop in sd_softdevice_enable. How can i investigate ?

Loop is from 0x00009DEA to 0x00009DF2

Target is nRF52832 AA with nRF5_SDK_13.0.0_04a0bfd / s132_nrf52_4.0.2_softdevice.hex

Does your sparkfun board have an external 32k Hz crystal? Try the interal RC:

nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;

clock_lf_cfg.source = NRF_CLOCK_LF_SRC_RC;
clock_lf_cfg.rc_ctiv = 16;
clock_lf_cfg.rc_temp_ctiv = 2;

// Initialize SoftDevice.
SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);

I tried NRF_CLOCK_LFCLKSRC, was not OK No output on RTT...

Very strange, it works with Arduino on nRF52 (Sparkfun tutorial, SD132 2.0.1) !!!!!! It's probably a difference in SD132...

SD132 2.0.x works with SDK11... Just flash SD (using nRF Studio or other tools). You can find it in your SDK\components\softdevice\s132\hex Check compatibility matrix here

Hello, First thank you Sigurd and Luk3 for your help. About matrix i checked my nRF52 is a rev 1 so that should be right for both. I re soldered my nRF52. I still have issue with Crystal and RC clock with SDK (not with Arduino). I noticed that i have an hardfault on debugger (Ozone). How can i investigate ?
