porting from STM32L4 to nrf52840

Given the following overlay for my hardware I can get a the following messages on the USB com port: 

---- Opened the serial port COM11 ----
[00:00:00.332,672] <err> net_if: There is no network interface to work with!
*** Booting nRF Connect SDK v2.9.0-7787b2649840 ***

[00:00:00.333,068] <err> app_main: No network interface configure

Problem: The SPI does not seem to be engaged or the ADIN1110 has not been configured properly, no network interface. I will spend some time investigating the ADIN1110 configuration pins at the datasheet, as well as engaging the SPI some where to confirm my setup at the nRF52840 dongle level.

Question: Is there any glaring config, or overlay that has not been attended?

The proj.conf has been edited to engage the SPI as follows: 

Hi drollinger 

To avoid duplication, I'm closing this thread as there is another one open for the same query. Please follow up there if you have any questions.

Kind regards,

Given that I have been able to cobble together an SPI communication from the nrf52840 to the ADIN1110 I see the following results: SPI MOSI writes a buffer: 0x00, 0x80, 0x01, 0x00, 0x00,0x00, 0x00, 0x00(visualized with scope) and receives data a creates a buffer on MISO: 0x00, 0xFF, 0xFF, 0xFF, 0x00, 0x00, 0x00( visulaized with scope) with the following voltages on the ADIN1110 (multimeter): 

1 MOSI 0.00
2 MISO 0.00
3 0.00
4 0.00

Any help as to why I have not received a 0x283c91 would be greatly appreciated!
