[参考译文] DP83869HM：无法在网络上建立通信。

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1606969/dp83869hm-unable-to-establish-communications-onto-network

器件型号： DP83869HM
主题： DP83869 中讨论的其他器件

我有一个与 DP83869 光纤连接的定制 PCB、无法在网络上建立任何通信。 我随附了原理图的屏幕截图。 以及器件树段。

sfp0: sfp {
		compatible = "sff,sfp";
		maximum-power-milliwatt = <2000>;
		i2c-bus = <&i2c3>;
};

&fec {
	status="okay";
	phy-handle = <&ethphy1>;
	phy-mode = "rgmii-id";
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&pinctrl_fec>;
	pinctrl-1 = <&pinctrl_fec_sleep>;

	eth2_mdio: mdio {
		#address-cells = <1>;
		#size-cells = <0>;
		ethphy1: ethernet-phy@0 {
			compatible = "ethernet-phy-ieee802.3-c22","ethernet-phy-id2000.a0f1";
			device_type = "ethernet-phy";
			// interrupts not being processed correctly. using polling mode for now
			// interrupt-parent = <&gpio4>;
			// interrupts = <18 IRQ_TYPE_LEVEL_LOW>;
			reg = <0>;
			sfp = <&sfp0>;
			ti,op-mode = <DP83869_RGMII_1000_BASE>;
		};
	};
};

我的系统能够识别 PHY 并识别载波：  

ethtool 输出：  

`IP A`输出

`ifconfig eth0`的输出
