器件型号：AM4378

更新 SDK (和内核)版本后、我们正在努力使以太网接口正常工作。

我随函附上以下文件的原文和新版本：

设备树
内核日志
内核.config

按照 https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1052711/am4378-linux-5-10-ethernet-no-longer-works?tisearch=e2e-sitesearch&keymatch=davinci_mdio_sw#中的示例、在 devicetree 中、我已更改

&mac {
	slaves = <1>;
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&mii1_pins_default>;
	pinctrl-1 = <&mii1_pins_sleep>;
	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 = "mii";
};

输入

&mac_sw {
	slaves = <1>;
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&mii1_pins_default>;
	pinctrl-1 = <&mii1_pins_sleep>;
	status = "okay";
};

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

	ethphy0: ethernet-phy@0 {
		reg = <0>;
	};
};

&cpsw_port1 {
	phy-handle = <&ethphy0>;
	phy-mode = "mii";
	ti,dual-emac-pvid = <1>;
};

但接口未出现。

有什么想法吗？

谢谢大家、此致
Peter
