What I was meaning was not to try stuff like "SGMII", but try the _other_ three flavours of RGMII. In other words: rgmii rgmii-txid rgmii-rxid If u-boot works, and it's using RGMII, then it's definitely one of the four flavours of RGMII interface. No need to post the failures of the testing to the forums - just say here whether any of those result in packet flow or not. Nothing else should change - the only difference between these modes are the timings of the RGMII interface, and having the wrong mode is the most common reason for RGMII not working. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
