Custom PCB nRF7002 on 5340

We have a new custom PCB that has been extensively reviewed that we believe is wire correctly.

The developer on the board uses Segger and wants to do some basic testing outside of installing nrfConnect and using Zephyr.  I saw a low level access to the 7002 in a library but don't see much documentation. 

Can anyone advise a simple test to prove that the 5340 and the 7002 are able to communicate on a new PCB?  

We do have zephyr running on our PCB, but looking for something lower level to do basic testing.

thanks in advance.
