Is CPSW dropping outgoing packages?

How could we be sure, that CPSW is forwarding packages from port0 to port2 like a hub?

Hi,

Where is the tcpdump being captured?

Please attach the results of ethtool -S eth1. This will show the TX packets at the MAC level or packets that were sent by the CPSW.

Best Regards,

Schuyler

Hi,

Thank you for the results of the ethtool command.

This line indicates the CPSW is sending packets:

Good Tx Frames: 155

The tcpdump is on the DUT, this means it will what was sent to the driver.

Looking through the DTS I see the CPSW has both ports initialized, are you seeing both interfaces with this command:

ifconfig -a

Could you please post the results of that command?

Best Regards,

Schuyler

Is this in DTS maybe better? We want to use only eth1.

&mac {
    status = "okay";
    slaves = <2>;
    active_slave =<1>;
    // phy-mode = "mii";
    //#address-cells = <1>;
    //#size-cells = <0>;
    pinctrl-names = "default";
    pinctrl-0 = <&mii2_pins>;
    dual_emac ;
    // fixed-link {
    //  speed = <100>;
    //  full-duplex;
    // };
};

&cpsw_emac1 {
    phy-mode = "mii";
    dual_emac_res_vlan = <3>;
    fixed-link {
        speed = <100>;
        full-duplex;
    };      
};

What could be better fixed-link or phy-handle?

&mac {
    status = "okay";
    slaves = <2>;
    active_slave =<1>;
    // phy-mode = "mii";
    //#address-cells = <1>;
    //#size-cells = <0>;
    pinctrl-names = "default";
    pinctrl-0 = <&mii2_pins>;
    dual_emac ;
    // fixed-link {
    //  speed = <100>;
    //  full-duplex;
    // };
};

&cpsw_emac1 {
    phy-mode = "mii";
    dual_emac_res_vlan = <3>;
    phy-handle <&eth_phy1>      
};

Do you have a reference or an example for eth_phy1?

Only receiving ARP works. Why only receiving and not sending?

Switched of VLAN. Ping works.
