Unable to initialize BLE

[OlaHallstrom]

Hello,

Application crashes at "nrf_sdh_enable_request()" without returning any error code. Execution up to this seems fine and I get RTT debug prints. I have also tried some examples, ble_beacon for instance, and this works fine. The application has been converted from an IAR project working ok before, but that was with older SDK/softdevice (15.0.0).

SES 5.10

nRF52832_xxAA (custom hardware with external crystal)

SDK 17.0.0

S132

Where do I start investigating? What needs to be fulfilled for the application/softdevice interaction to work as expected?

Thanks

Sometimes an external 32kHz crystal oscillator doesn't; the starting point is to try without using that external crystal similar to this suggestion nrf_sdh_enable_request-doesn.t

Ok thanks, some clarification: I have a HFXO but no LFXO. I have tried several settings for the source of LFCLK, I guess in my case either internal RC or SYNTH would be doable. Neither of those settings works however. I have verified that my HFCLK is starting ok. Also the SDK examples run fine so the hardware should be ok.

Do you mean that it still crashes at nrf_sdh_enable_request?

Can you share your exact clock configuration?
