工具与软件：
您好、TI：
我们正在尝试 使用 AM62a3配置88E1512。 以下是我的设备树配置：
&cpsw3g {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_rgmii1_pins_default>;
};
&cpsw_port1 {
status = "okay";
phy-mode = "rgmii";
phy-handle = <&cpsw3g_phy0>;
mac-address = [00 00 00 00 00 00]; // newly added
phys = <&phy_gmii_sel 1>; // newly added
};
&cpsw3g_mdio {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_mdio1_pins_default>;
cpsw3g_phy0: ethernet-phy@0 {
reg = <0>;
ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
ti,min-output-impedance;
};
};
&main_pmx0 {
main_mdio1_pins_default: main-mdio1-pins-default {
pinctrl-single,pins = <
AM62AX_IOPAD(0x160, PIN_OUTPUT, 0) /* (V12) MDIO0_MDC */
AM62AX_IOPAD(0x15c, PIN_INPUT, 0) /* (V13) MDIO0_MDIO */
>;
};
main_rgmii1_pins_default: main-rgmii1-pins-default {
pinctrl-single,pins = <
AM62AX_IOPAD(0x14c, PIN_INPUT, 0) /* (AB16) RGMII1_RD0 */

AM62AX_IOPAD(0x154, PIN_INPUT, 0) /* (W15) RGMII1_RD2 */

AM62AX_IOPAD(0x13c, PIN_INPUT, 0) /* (Y16) RGMII1_TD2 */
AM62AX_IOPAD(0x140, PIN_INPUT, 0) /* (AA17) RGMII1_TD3 */
AM62AX_IOPAD(0x130, PIN_INPUT, 0) /* (AB17) RGMII1_TXC */
AM62AX_IOPAD(0x12c, PIN_INPUT, 0) /* (W16) RGMII1_TX_CTL */

};但无法检测到88e1512、也无法 ping 通。
