CC1352P: How to migrate my application based on ti154stack to custom PHY?

Hi, TI.

My application is based on SimpleLink SDK V5.20 ti154stack sensor example as below

My rf stack is TI 15.4 Stack which is the default stack in the example as below

My application works fine and now, I want to test some other phys in syscfg as below

I tried to remove TI 15.4 Stack in syscfg, and add a Custom phy, then compile, of course there are some compile errors.

So I want to ask, If I want to test Custom phy in syscfg, do I need to develop a new application based on another example? 

If so, which example should I use?

If not, please confirm, I'll continue to debug on this project to test Custom phy.

Thank you.
