Peripheral LBS not advertising with custom PCB (NCS V2.9.0)

[calibrexnick]

As the title suggests, I am trying to run the peripheral LBS example on my custom PCB to test BLE before continuing with my application. I'm using NCS V2.9.0.

I have created a custom kConfig file enabling the internal RC clock at 500ppm (I do not have an external lfclk).
I also have a simple device tree overlay. Both are specified in the build config, the firmware builds and flashes successfully but I do not see the device advertising.

Things I've tried: 

- Different RC PPMs
- Testing on DK (works as expected)
- Changing GPIO in the overlay

Things I'm considering:
- Swap out the load caps on the 32M xtal
- Strip out the button and LED altogether

Any help is greatly appreciated. Schematic attached.

Hi,

Have you checked the log, so that you see if there are any errors or if it seems like everythign stared successfully? If not, we need to look into the errors you see from the log. If all look sgood there, there could be an issue with the HFXO. Either wrong load cap value (causing a frequency offset), or another typical issue is that the crystal may be rotated 90 degrees (then it will not start at all).

Einar, following up here to close this out: I discovered that the load caps were not grounded . Attaching them to ground resulted in the device working as designed. Thanks for your help, time to go spin a new board!
