Program hangs on sd_softdevice_enable

Hi,

Im using Keil, S110 6.0.0 and a ble_app_hrs demo code.

I get a problem that the code hangs in sd_softdevice_enable. The board is a copy of the board from the dev kit with 16Mhz crystal. If i start HFCLK manually before SD starts - HFCLK is reported started, so there is no problem with the crystal. What else can the problem be?

Thanks!

Check your LFCLKSRC setting. Try the RC oscillator just to check (I've had boards produced with unreliable 32khz crystal connections.)

syntronics, you are absolutely right! i didnt have 32Khz installed at all and I didnt switch the source of LFCLK. Now I did switch it to internally generated and calibrated and SD initializes just fine. Unfortunately I still dont see BLE device. Any suggestions?
