TDA4VM: CPSW0 is unable to ping to the external network.

Hi,

As per above you are trying to bring up CPSW9G in Native Linux driver.

Can you please refer to FAQ[How to move to Native Linux driver for CPSW5G/CPSW9G].

It could be due to EthFw binary is mapped to MCU2_0 by default, you have to unlink ethfw image and add link other binary for example IPC echo test binary on MCU2_0. Refer to above FAQ how to change also refer the device tree file add following node when dorprocboot from u-boot is not set.

&main_r5fss0_core0 {
firmware-name = "pdk-ipc/ipc_echo_test_mcu2_0_release_strip.xer5f";
};

Best Regards,
Sudheer

Hi Sudheer

    Add this modification to the device tree, but still unable to ping the external network.

Hi,

Ping you are trying to do with IP 192.168.17.141 is on the same system from above ifconfig log.

Can you please connect the port intended to ping with external pc and check once. 

Also, I could see you have added pin mux only for rgmii3 and the ports you have enabled was port-1 and port-2 hiw you are getting linkup without proper pin muxing for the port-1, port-2.

My computer's IP：

eth0 can automatically obtain the IP, eth1/eth2 cannot obtain the IP.

eth0 can ping to connect to the external network. eth1/eth2 cannot ping to connect to the external network.

The PC cannot ping eth1/2.

Please help me investigate what caused it? Thank you.

Hi,

From Schematic it seems like you are using Port-3, Port-8. So, you need enable "cpsw0_port3 & cpsw0_port8".
Your Port configuration should be as follows.

&cpsw0_port1 {
    status = "disabled";
};

&cpsw0_port2 {
    status = "disabled";
};


&cpsw0_port3 {
    phy-handle = <&cpsw9g_phy0>;
    phy-mode = "rgmii-rxid";
    mac-address = [00 00 00 00 00 00];
    phys = <&cpsw0_phy_gmii_sel 3>;
};

&cpsw0_port4 {
    status = "disabled";
};


&cpsw0_port5 {
    status = "disabled";
};

&cpsw0_port6 {
    status = "disabled";
};

&cpsw0_port7 {
    status = "disabled";
};

&cpsw0_port8 {
    phy-handle = <&cpsw9g_phy1>;
    phy-mode = "rgmii-rxid";
    mac-address = [00 00 00 00 00 00];
    phys = <&cpsw0_phy_gmii_sel 8>;
};

Hi

After making these modifications, it is still not possible to ping the external network.

Please help me analyze it again, thank you.

Hi

   After adding a delay, it was resolved. thanks！
