[LS1046] 10G ethernet packet error issue

charleshuang — Thu, 18 Jul 2024 01:11:33 GMT

Hi NXP team,

Our client feedbacks an issue where "Rx Error Packets" appear when testing the LS1046 with the AQR113 10G module.

The client's setup is as follows picture, and the issue can be reproduced regardless of whether the bandwidth is 10G or 1G. Please provide some suggestions to help us solve this issue. Thank you ~

And we have observed a phenomenon where, in a 10G environment, the port fm1-mac1 cannot display the connection speed using ethtool.
We are not sure if these two issues are related.

BR.

In the dts of ls1046ardb, fm1-mac10 is defined as fixed-link to support SFP+ module.

ethernet@f2000 { /* 10GEC2 */
fixed-link = <0 1 1000 0 0>;
phy-connection-type = "xgmii";
};

On your target board, you are using AQR113 10G external PHY, please define the Ethernet port similar as ethernet@f0000.

Please modify "reg = <0x0>" with the MDIO PHY address of AQR113 PHY.

In addition, please enable AQR113 PHY driver in Linux Kernel configuration file.

ethernet@f2000 { /* 10GEC1 */
phy-handle = <&aqr113_phy>;
phy-connection-type = "xgmii";
};

mdio@fd000 {
aqr106_phy: ethernet-phy@0 {
compatible = "ethernet-phy-ieee802.3-c45";
reg = <0x0>;
};
};
