BLE softdevice clock running slower

[siri sam]

Hi,

I'm working on a custom board with the nrf52840 engineering version n52840QIAABB with de SDK15. I've tried the exemple usbd_ble_uart from the SDK15 and it works well. I was able to find my device with Nrf connect and as a Port COM. When i have implemented the ble to my own firmware,  the devices was recognize by the computer but the bluetooth didn't work. On debug,everyting is initialized ans the soft is running. The LED on my board was blinking slower than it should be. It seems that the clock is running slower. It also appears that i cannot run the exemple anymore. The issue appends since i added the softdevice to my firmware.

Hello.

I don't think adding the softdevice to the firmware can damage the clocks on the chip.

Is it only the examples that are using the softdevice that aren't working?

Are the other examples, such as the ones found in SDK\examples\peripheral working properly?

 

Do you have a LFXTAL on your custom board? Or do you use the RC Oscillator?

 

Best regards,
