请问okmx6ul-c2与nand256m是如何配置双网口的

问答对人有帮助，内容完整，我也想知道答案 0 核心板：okmx6ul-c2，内存nand256m。内核：linux.3.14.38 配置双网口时，报错如下： ifdown: intece eth0 not configured ifdown: intece eth1 not configured [ 16.598548] fec 20b4000.ethernet eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=20b4000.ethernet:01, irq=-1) [ 16.648665] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 16.838556] fec 2188000.ethernet eth1: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=20b4000.ethernet:02, irq=-1) [ 16.888678] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready 操作过程如下： 1、修改设备树文件“vi ./arch/arm/boot/dts/imx6ul-14x14-evk-emmc-c2-7-1024x600.dts” 2、修改内容，屏蔽fec1中的mdio： &fec1 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_enet1>; phy-mode = "rmii"; phy-handle = <ðphy0>; status = "okay"; /* mdio { #address-cells = <1>; #size-cells = <0>; ethphy0: ethernet-phy@1 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <1>; }; ethphy1: ethernet-phy@2 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <2>; }; }; / }; 3、在fec2写mdio： &fec2 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_enet2>; phy-mode = "rmii"; phy-handle = <ðphy1>; status = "okay"; mdio { #address-cells = <1>; #size-cells = <0>; ethphy0: ethernet-phy@2 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <2>; }; ethphy1: ethernet-phy@1 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <1>; }; }; }; 4、修改引脚复用，屏蔽网口2GPIO imx6ul-evk { pinctrl_hog_1: hoggrp-1 { fsl,pins = < MX6UL_PAD_LCD_RESET__WDOG1_WDOG_ANY 0x30b0 MX6UL_PAD_UART1_RTS_B__GPIO1_IO19 0x17059 / SD1 CD / MX6UL_PAD_GPIO1_IO05__USDHC1_VSELECT 0x17059 / SD1 VSELECT / MX6UL_PAD_GPIO1_IO09__GPIO1_IO09 0x17059 / SD1 RESET */ MX6UL_PAD_UART1_CTS_B__GPIO1_IO18 0x3008 //MX6UL_PAD_UART2_TX_DATA__GPIO1_IO20 0x3008 //MX6UL_PAD_UART2_RX_DATA__GPIO1_IO21 0x3008 MX6UL_PAD_UART2_CTS_B__GPIO1_IO22 0x3008 MX6UL_PAD_UART2_RTS_B__GPIO1_IO23 0x3008 //MX6UL_PAD_UART3_TX_DATA__GPIO1_IO24 0x3008 //MX6UL_PAD_UART3_RX_DATA__GPIO1_IO25 0x3008 MX6UL_PAD_UART3_CTS_B__GPIO1_IO26 0x3008 MX6UL_PAD_UART3_RTS_B__GPIO1_IO27 0x3008 //MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x3008 //MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x3008 //MX6UL_PAD_UART5_TX_DATA__GPIO1_IO30 0x3008 //MX6UL_PAD_UART5_RX_DATA__GPIO1_IO31 0x3008 //MX6UL_PAD_ENET2_RX_DATA1__GPIO2_IO09 0x3008 //MX6UL_PAD_ENET2_RX_EN__GPIO2_IO10 0x3008 //MX6UL_PAD_ENET2_TX_DATA0__GPIO2_IO11 0x3008 //MX6UL_PAD_ENET2_TX_DATA1__GPIO2_IO12 0x3008 //MX6UL_PAD_ENET2_TX_EN__GPIO2_IO13 0x3008 //MX6UL_PAD_ENET2_TX_CLK__GPIO2_IO14 0x3008 //MX6UL_PAD_ENET2_RX_ER__GPIO2_IO15 0x3008 MX6UL_PAD_LCD_DATA16__GPIO3_IO21 0x3008 MX6UL_PAD_LCD_DATA17__GPIO3_IO22 0x3008 5、屏蔽网口1MDIO，使能网口2MDIO pinctrl_enet1: enet1grp { fsl,pins = < //MX6UL_PAD_GPIO1_IO07__ENET1_MDC 0x1b0b0 //MX6UL_PAD_GPIO1_IO06__ENET1_MDIO 0x1b0b0 MX6UL_PAD_ENET1_RX_EN__ENET1_RX_EN 0x1b0b0 MX6UL_PAD_ENET1_RX_ER__ENET1_RX_ER 0x1b0b0 MX6UL_PAD_ENET1_RX_DATA0__ENET1_RDATA00 0x1b0b0 MX6UL_PAD_ENET1_RX_DATA1__ENET1_RDATA01 0x1b0b0 MX6UL_PAD_ENET1_TX_EN__ENET1_TX_EN 0x1b0b0 MX6UL_PAD_ENET1_TX_DATA0__ENET1_TDATA00 0x1b0b0 MX6UL_PAD_ENET1_TX_DATA1__ENET1_TDATA01 0x1b0b0 MX6UL_PAD_ENET1_TX_CLK__ENET1_REF_CLK1 0x4001b031 >;
