As a starter try simple flows : "in_port=A, out_port=B", "in_port=B,out_port=A", so that you don't have to worry about ARPs. Try this for your single-switch setup, and two-switches. Make sure there is no controller connected, otherwise there might be conflicts between your flows and what the controller tries to do.
