Cann't run the BLE code

[Alice]

Hi

I met a problem when I use my new board,I found that the example in the peripheral folder in SDK can run correctlly,but the the example in the ble_peripheral folder cann't work.Afterwards，I found that it is because the ble_stack_init() function.Pls see the attachment.(/attachment/fdae08a039f8b65fb17766e1a4d96923) The SDK I use is 8.0,S110_V8.0,and the chip is nRF51822 QFAC A 1506.I know the problem is not software problem.Also,I have checked the 16M crystal,which is 20ppm.

Anyone could tell me what reason may be?Thank you very much.

Do you have a 32kHz crystal on the board? If not, are you changing the ble init to use a synthesized 32kHz source?

Yes,I have a 32kHz crystal on the board.I also try to use NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION,but the problem still cann't be solved.
