ble_stack_init nrf_sdh

[Cy]

I am inquiring about a custom device that hangs in the ble_stack_init(); and the result is a fatal error.

The custom device has an nRF52832 

The SDK is the SDK14

The project is a basic UART over bluetooth

The project will run without the fatal error on a nRF52832 DK

I have turned on debugging and have been given three statements:

<info> app: here
0> <debug> nrf_sdh: State request: 0x00000000
0> <debug> nrf_sdh: Notify observer 0x0002B474 => ready
0> <debug> nrf_sdh: State change: 0x00000000
0> <error> app: Fatal

Any help provided would be appreciated.

So, I have 5 custom boards with the same components, and one board out of the 5 will connect to the nRF connect through a USB nRF52840 dongle. The board can use either configuration given in the SDK_config.h file. The other four boards fail either way. I have created the boards and therefore variability in the circuit could exist.
