There's the same behaviour on Gen5, e.g. CycloneV where we have the "EMAC splitter". Based on wether or not we have that splitter in DT, we override the INTF_SEL bits to set GMII as the MAC output, the splitter converting that to RGMII/SGMII. Is there something similar on this AgileX5 version by any chance, for which we could reuse the logic ? I know that on CycloneV you also need to adjust that GMII -> RGMII/SGMII splitter whenever the speed changes, is that different on agileX5 ? have you tested 10/100Mbps ? Thanks, Maxime
