SGMII core configuration without MDIO

Jump to solution

To config a SGMII core running 100mbps, can I just use an_adv_config_vector[]15:0] to config that speed, without use the MDIO port as the attached ?

Hey @mengmcxl,

Yes, the MDIO Management Interface is optional. You can actually remove it by re-customizing the IP, then go the "Core Functionality" tab and uncheck "MDIO Management Interface".

Table 2-9 in PG047 shows how most of the registers can be written without MDIO, but it looks like you've already taken care of that.
