Hi,
We are using T1024 SoC for our custom board development. The Lane A (SD1_RX0_P, SD1_RX0_N,SD1_TX0_P,SD1_TX0_N) of SerDes is configured in 10G XFI mode with RCW configuration [RCW[128:136] = 0x95]. This SerDes LANE has been connected with a 10G SerDes port of an Ethernet switch.
Our requirement is to establish a fixed link (Link Up) between the SerDes interface of T1024 and Ethernet-Switch.
1. In the switch side, the SerDes 10 is configured in 10G XFI mode and the link is forced up. Similarly, how to force the 10G MAC Link (fm1-mac1) for the T1024 SerDes. Kindly provide your suggestions.
There is no PHY between SerDes of T1024 and switch.
Thanks,
S.Abinesh.
Hi,
Please find the below attached image showing the interface between T1024 and Ethernet Switch.
Observation:
The interface "fm1-mac1" is linked up using "ifconfig fm1-mac1 <ipaddr>". Then, we try to ping the switch via this interface and the "tcp-dump command" (running in T1024) shows the ARP packet sending out from this interface. But, in the SWITCH side (in SerDes 10), the RX counter is not incremented.
It is observed that, the the Tx packet counter (0xFE4E0200 + 0xC4) in T1024 MAC1 is not increment and it remains 0.
Following DTS change has been added to enable fixed link in 10G MAC,
fm1mac1: ethernet@e0000 {
phy-connection-type = "xgmii";
fixed-link = <1 1 10000 0 0>;
rcpm-wakeup = <&rcpm 0x80000000>;
};
Following DTS entry that has been removed,
xmdio0: mdio@fd000 {
xg_aqr105_phy3: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c45";
interrupts = <0 1 0 0>;
reg = <0x1>;
};
sg_2500_aqr105_phy4: ethernet-phy@2 {
compatible = "ethernet-phy-ieee802.3-c45";
interrupts = <0 1 0 0>;
reg = <0x2>;
};
};
The register dump of T1024 SerDes Lane A in U-boot shows that, it is configured in XFI mode and connected with MAC1 interface. Please let us know, what could be issue with the MAC in sending this packets? Link is down?.
