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: inte**ce eth0 not configured
ifdown: inte**ce 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_ENET2_TX_DATA1__GPIO2_IO12 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
>;
};
pinctrl_enet2: enet2grp {
fsl,pins = <
MX6UL_PAD_GPIO1_IO07__ENET2_MDC 0x1b0b0
MX6UL_PAD_GPIO1_IO06__ENET2_MDIO 0x1b0b0
MX6UL_PAD_ENET2_RX_EN__ENET2_RX_EN 0x1b0b0
MX6UL_PAD_ENET2_RX_ER__ENET2_RX_ER 0x1b0b0
MX6UL_PAD_ENET2_RX_DATA0__ENET2_RDATA00 0x1b0b0
MX6UL_PAD_ENET2_RX_DATA1__ENET2_RDATA01 0x1b0b0
MX6UL_PAD_ENET2_TX_EN__ENET2_TX_EN 0x1b0b0
MX6UL_PAD_ENET2_TX_DATA0__ENET2_TDATA00 0x1b0b0
MX6UL_PAD_ENET2_TX_DATA1__ENET2_TDATA01 0x1b0b0
MX6UL_PAD_ENET2_TX_CLK__ENET2_REF_CLK2 0x4001b031
6、保存并编译设备树,生成三个dtb文件:
root@ubuntu:/home/weitao/Downloads/linux-3.14.38# make dtbs
DTC arch/arm/boot/dts/imx6ul-14x14-evk-emmc-c2-7-1024x600.dtb
DTC arch/arm/boot/dts/imx6ul-14x14-evk-gpmi-c2-256m-7-1024x600.dtb
DTC arch/arm/boot/dts/imx6ul-14x14-evk-gpmi-c2-1g-7-1024x600.dtb
7,将dtb文件,拷贝至目录”G:\飞凌linux\OKMX6UL-C2(eMMC&Nand版)用户资料-20190709\Linux\工具\OTG\mfgtools\Profiles\Linux\OS Firmware\files\linux\dtb“
8,拨码开关8OFF,其他ON,重启核心板,使用mfgtools脚本更新程序
9、运行后,在超级终端中,可看到两个网口,但ping不通

10,若只配置网口1,网口2disable,网口1可正常使用。
11、自制的底板,网口PHYAD与资料的反过来了,自制底板的网口1的PHYAD0=0, PHYAD1=1,网口2PHYAD0=1, PHYAD1=0,的网口部分见附件:
12、PHYAD物理接线的改变,在设备树中分别修改MDIO如下,均不起作用
ethphy0: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
};
ethphy1: ethernet-phy@2 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <2>;
};
或者:
ethphy0: ethernet-phy@2 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <2>;
};
ethphy1: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
};
求助:请问,okmx6ul-c2,nand256m,如何配置双网口?在资料”OKMX6UL-C2(eMMC&Nand版)用户资料-20190709“中,未看到相关说明。
