SerDes protocol 0x099 is used on our T1023 board.  the EC2(FMAN MAC3) is connect to boardcom switch 5389 directly, so there is no PHY or MIDO associated with EC2.


How can I config this interface in your u-boot function "board_eth_init" in "eth_t102xrdb.c" , currently I bypass the all setting functions for FM1_DTSEC3, so no phy addr or mdio is associated. But the I can not send anything via the EC2, ping cmd does not work.

1. fm_info_set_phy_address

2. fm_info_set_mdio 


=> ping
Using FM1@DTSEC3 device

ARP Retry count exceeded; starting again
ping failed; host is not alive




My phys on other ports of the BCM switch are already link up. 

Could you tell me what am I missing on setting FM1_DTSEC3?
