AM3352 Custom Board with dual ethernet

Hi,

Do you have the following node in your am335x-evmsk.dts:
&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
dual_emac = <1>;
};

Also can you try the ifconfig -a command?
Can you try adding auto eth1 in /etc/network/interfaces ?

Best Regards,
Yordan

Thank you you reply Yordan.

Sorry, yesterday I enabled the dual_emac = <1>; but I think I put the wrong dtb in the boot partition.

Now I can see the eth1. Unfortunately the eth1 even if visible still does not work, I can do "ifup eth1", I can assign a static IP (on a different network than eth0) but I cannot ping any host. Maybe some kernel patch is required for the LAN8710A?

This is the ifconfig -a:

and here my /etc/network/interfaces

For the DTS I take from evm:

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

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

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

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

The ethtool shows:
