如果我打算仅在基于 i.MX8M Plus Evk 的自定义板中使用以太网 fec,并且我更改了 uboot 设备树文件,如下所示。那是对的吗 ?
&fec {
pinctrl-names = "默认";
pinctrl-0 = <&pinctrl_fec>;
phy-mode = "rgmii-id";
phy-handle = <ðphy0>;
fsl,魔术包;
状态=“好的”;
mdio {
#address-cells = <1>;
#size-cells = <0>;
ethphy0: ethernet-phy@1 {
compa
tible = "ethernet-phy-ieee802.3-c22";
注册 = <1>;
eee-broken-1000t;
};
};
};
&iomuxc {
pinctrl-names = "default";
pinctrl_fec: fecgrp {
fsl,pins = <
