We are starting to develop on a custom board running an NRF5340; when we try even something very simple like the iBeacon demo, we are unable to start bluetooth. Below are the output messages from the console:

Starting iBeacon Demo
[00:00:01.001,220] <err> bt_hci_driver: Endpoint binding failed with -11
[00:00:01.001,251] <err> bt_hci_core: HCI driver open failed (-11)
Bluetooth init failed (err -11)
I think the issue might be clock related - we dont have an external LFXO, only the high frequency Xtal on XC1 and XC2. The other code (SPI, GPIO) all seem to work.
Here is our prj.conf file if that helps:

I can include the entire Build folder if you would like.
I am programming through VSCode, and can confirm there is _something_ in the network core.
We are using SDK 2.5 if that helps somehow.
Thank you for your time and assistance!
