LS1012A-FRWY Ethernet not working at 1000Mb/s

[smh]

I have been working with the LS1012A-FRWY development board and I have been trying to connect two boards together via Ethernet. I have tried the connection using both a crossover cable and a normal cable. When the Ethernet ports are connected with a speed of 1000Mb/s, 50% of packets over the connection get dropped. When the speed is reduced to 100Mb/s, there is no packet loss.

However, when the boards are connected through an Ethernet Switch, they can successfully communicate at 1000Mb/s.

I have also tried switching between the eth0 and eth1 ports and both react the same way when connected directly to another board. They both work fine at 1000Mb/s when connecting to our LAN.

What could be the problem?

Thanks

There is active development work going on to correct this issue.  It is dependent on the device on the other side of the Ethernet cable, and does not show up in many of the combinations.  Connecting the FRWY board to other LS1012A based boards does not exhibit the issue.
