We are having T1022 processor customized board , the SERDES configuration used in the RCW is 0x40. The EC1 is connected to ethernet marvel switch (88E6320) port 5 with RGMII interface. Now we have initialised marvel switch port 5 with following configuration - speed 1G , full duplex autoneg off with forced link up. The processor is able to receive ICMP packets from switch but is not sending the ICMP reply. All delay combination of rgmii have been tried in device tree as well as in switch.
I am attaching device tree which i am using for the above purpose.
