Part Number: AM3354

Hi,

Main chip : AM3354BZCZ100

Network chip : KSZ9031RNXCC

SDK： RT-3.3 Device Tree ： am335x-boneblack.dtb

There is a problem: ifconfig or udhcpc-i eth0 can not get the network address.

The hardware connection is as follows:

The device tree is as follows:

&cpsw_emac1 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "mii";
status = "okay";
};

&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
status = "okay";
};

&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;
status = "okay";
};

Kernel printing information is as follows:

Can you post the full bootlog and the dts file, which you're using?
Also please share which SDK is this?

Hi,

Can you try enabling the dual emac:
&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
status = "okay";
+ dual_emac;
};
&cpsw_emac1 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "mii";
status = "okay";
+ dual_emac_res_vlan = <2>;
};

Best Regards,
Yordan

Hi Yordan，

Thank you for your reply .

I enabling the dual emac.

Device tree according to the above configuration.

But eth0 eth1 still has no network address. As shown in the following figure：

Hi,

Try the following:
&mac {
+ slaves = <1>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
status = "okay";
};

This way you tell the cpsw driver that you have a slave connected, so it configures that slave.

Hi,

Thank you for your reply .

Add to slaves = <1>;

Unable to obtain network address.

Plug in the net, not display link is up.

Where do you need to modify it ?

Hi,

Which linux sdk is this?

Try enabling both eamc0 and emac1 and use dual_emac. You can take the am335x-evmsk.dts as a reference:
&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
dual_emac = <1>;
status = "okay";
};

&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;
status = "okay";
};

&cpsw_emac0 {
phy_id = <&davinci_mdio>, <0>;
phy-mode = "rgmii-txid";
dual_emac_res_vlan = <1>;
};

&cpsw_emac1 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "rgmii-txid";
dual_emac_res_vlan = <2>;
};

Best Regards,
Yordan

Hi,

Can you try:
ifconfig eth1 up
ifconfig eth1 <ip address>

What is the output? How is your network configured? By default the ethernet interface is configured as dhcp, so you should have a dhcp server that assigns the IP addresses in your local network.

Yordan
