Dual Gigabit Ethernet or only Single Gigabit plus Single Fast Ethernet?


Reading through the Errata of AM5728 at http://www.ti.com/lit/er/sprz429j/sprz429j.pdf section i880:

“RGMII2 (rgmii1_* signals) Switching Characteristics only support 10/100 Mbps operation”

Does that mean that Gigabit is only supported on one of the two ports? If yes: Will this be fixed in a newer silicon?

I did some experiments with iperf and got speeds way above 100Mbps TCP. Maybe I just connected to the true Gigabit port.



Based on the current design, they are both working at 1G. TI will not guarantee that it will work at 1G.
