Using ARM processor in f1 FPGA instance

Hi,

I have to connect my design with ARM processor and I have to create 2 AFIs with the same design. One is transmitter and another is receiver. But both have to be configured in a different way so that it will act as transmitter and receiver. But the thing is, register addresses of both transmitter and receiver are same since both AFIs have same offset address. Also, I want to do P2P transmission. How can I achieve this by configuring both registers with same addresses? Also is it possible to connect ARM to AWS Shell? And how to do P2P transmission? The example provided in github is little confusing.

Thank you.
