The speed only is 10Mbit/s of the SGMII on LS1023, the interface use SFP moudle. How to config the interface about the speed of SGMII. hardware design as follow diagram:

我司使用LS1023的serdes Line A和Line B接口，配置成SGMII, 外面直接接SFP模组，但是其速度只有10Mbit/s，请问题怎么去配置这个接口的速度，硬件设计示意图如下：

the configuration of serdes as follow figure:

serdes配置如下：

Hello 康 张,

SGMII : 1 lane @1.25Gbps or 3.125Gbps.

XFI : 1 lane @ 10.3125 Gbps

Please check whether configuring SRDS_PRTCL_S1 lane A as XFI.m9 connecting to 10G SFP module meets your requirement on LS1043 platform.

Please to SerDes1 Lane0 and Lane1 hardware design on LS1046ARDB from QorIQ® LS1046A Reference Design Board | NXP , SerDes1 Lane1 is configured as XFI connecting SFP module, SerDes1 Lane0 could be configured as SGMII connecting 2.5G PHY for RJ46 port.

Thanks,

Yiping
