I see that PF_14, PF_15 and PG_00 through PG_05 are available on the P5 connector. But, looking at the SC589-EZ schematics it would appear that PF_13 (ETH1_CRS) is necessary to connect to an RMII PHY. I have to wonder if this pin is actually connected to the P5 connector but with a different name?
To clarify my intentions... my hope is to enable an ethernet bridge function between ETH0 and ETH1. The idea is that 2 of the Audio Modules would be directly connected to each other via the ETH0 gigabit connection and actively transmitting audio over AVB between them. But I would also like to connect two outside devices that transmit minor tcp/ip data and enable them to communicate with each other as well as with the two Audio Modules. Is this kind of bridge possible?
