-【迅为imx6q】开发板， 2G DDR

TF 16G SD卡，用于迅为imx6q SD 卡启动

RTL8211E

通过迅为imx6q 开发板原理图了解到，网卡 PHY 芯片是 RTL8211E，

在 u-boot .04 上，通过使能CONFIG_PHY_REALTEK配置，使能 RTL8211E 网络 PHY 芯片的支持，再配置设备树，增加PHY 复位延时，u-boot 下的网络就正常工作了。

这里有个选项：#define CONFIG_FEC_MXC_PHYADDR 0，也就是迅为imx6q 开发板上的 RTL8211E 网络 PHY 地址是 0。

适配方法

一、Linux 上开启 REALTEK

使用 menuconfig 图形配置，使能[*] Realtek devices

.config - Linux/arm 5.15.71 Kernel Configuration> Device Drivers > Network device support > Ethernet driver support> [*] Realtek devices<*>RealTek RTL-8139 C+ PCI Fast Ethernet Adapter support<*>RealTek RTL-8129/8130/8139 PCI Fast Ethernet Adapter support[ ] Use PIO instead of MMIO[ ] Support for uncommon RTL-8139 rev. K (automatic channel equalization) [ ] Support for older RTL-8129/8130 boards[ ] Use older RX-reset method<*>Realtek 8169/8168/8101/8125 ethernet support

RTL8211E与其他的 PHY 类似，所以可以同时使能其他的PHY 芯片的支持，当前 RTL8211E 还需要在设备树文件中定义一些参数。

二、修改设备树

设备树文件，可以自己复制一份

$ cp arch/arm/boot/dts/imx6q-sabresd.dts arch/arm/boot/dts/imx6q-topeet.dts

$ cp arch/arm/boot/dts/imx6qdl-sabresd.dtsi arch/arm/boot/dts/imx6qdl-topeet.dtsi

修改arch/arm/boot/dts/Makefile，增加生成imx6q-topeet.dtb

修改arch/arm/boot/dts/imx6qdl-topeet.dtsi，改动点有两处：

（1）是reg = <0>;，因为迅为imx6q 开发板 PHY 地址是 0（2）增加PHY 复位的延时reset-assert-us = <10000>;与reset-deassert-us = <150000>;

&fec {pinctrl-names = "default";pinctrl-0 = <&pinctrl_enet>;phy-mode = "rgmii-id";phy-handle = <&phy>;fsl,magic-packet;status = "okay";mdio {#address-cells = <1>;#size-cells = <0>;phy: ethernet-phy@0 {reg = <0>;qca,clk-out-frequency = <125000000>;reset-gpios = <&gpio1 25 GPIO_ACTIVE_LOW>;reset-assert-us = <10000>;reset-deassert-us = <150000>;};};};

调试经验

开始只改了 PHY 支持与增加 PHY 芯片的复位时间，发现工作不正常，提示信息如下

[ 1.826654] mdio_bus 2188000.ethernet-1: MDIO device at address 1 is missing.[ 1.834410] fec 2188000.ethernet eth0: registered PHC device 0

mdio_bus 2188000.ethernet-1: MDIO device at address 1 is missing.这个信息不能忽略，通过搜索Linux 内核代码，找到了这个信息的位置，初步认为是 PHY 地址有问题，通过增加LOG继续排查，发现从设备树读取的PHY 地址是 1，而 u-boot 下 PHY 地址设置的是 0。文件drivers/net/mdio/of_mdio.cof_mdiobus_register函数中

int of_mdiobus_register(struct mii_bus *mdio, struct device_node *np){struct device_node *child;bool scanphys = false;int addr, rc;if (!np)return mdiobus_register(mdio);/* Do not continue if the node is disabled */if (!of_device_is_available(np))return -ENODEV;/* Mask out all PHYs from auto probing. Instead the PHYs listed in* the device tree are populated after the bus has been registered */mdio->phy_mask = ~0;device_set_node(&mdio->dev, of_fwnode_handle(np));/* Get bus level PHY reset GPIO details */mdio->reset_delay_us = DEFAULT_GPIO_RESET_DELAY;of_property_read_u32(np, "reset-delay-us", &mdio->reset_delay_us);mdio->reset_post_delay_us = 0;of_property_read_u32(np, "reset-post-delay-us", &mdio->reset_post_delay_us);/* Register the MDIO bus */rc = mdiobus_register(mdio);if (rc)return rc;/* Loop over the child nodes and register a phy_device for each phy */for_each_available_child_of_node(np, child) {addr = of_mdio_parse_addr(&mdio->dev, child); /* #### 这里地址加了LOG，读取为 1 */if (addr < 0) {scanphys = true;continue;}if (of_mdiobus_child_is_phy(child))rc = of_mdiobus_register_phy(mdio, child, addr);elserc = of_mdiobus_register_device(mdio, child, addr);if (rc == -ENODEV) /* #### 这里应该是没有找到设备 */dev_err(&mdio->dev,"MDIO device at address %d is missing.\n",addr);else if (rc)goto unregister;}

解决方法就是修改设备树，把reg = <1>;改为reg = <0>;

其他修改

开发板的默认配置，编译烧写到 SD卡后，发现不断提示触摸屏读取错误，应该是触摸屏芯片驱动不匹配造成的，可以关闭触摸屏，后续在适配LCD 时一起适配好

烧写运行

这里使用 SD 卡启动，编译生成的产物为：

arch/arm/boot/zImagearch/arm/boot/dts/imx6q-topeet.dtb

烧写的方法，参考前面文章【迅为iMX6Q】开发板 Linux 5.15.71 SD卡启动，其实就是复制到 SD 卡的某个分区，然后设置 u-boot bootcmd，加载内核 zImage 与设备树 dtb 文件，然后 bootz 启动

/* 设置 bootargs，注意根文件系统放置的分区， mmcblk1p3， blk1 表示 sd 卡设备号 1， 3代表第三个分区 */setenv bootargs 'console=ttymxc0,115200 root=/dev/mmcblk1p3 rootwait rw'/* 设置 bootcmd ，注意linux zImage 与设备树 dtb 存放的分区 mmc 1:1 */setenv bootcmd 'ext4load mmc 1:1 0x18000000 imx6q-topeet.dtb; ext4load mmc 1:1 0x12000000 zImage; bootz 0x12000000 - 0x18000000'/* 保存 env */saveenv/* 重启 */reset

连接路由器

需要通过网线，连接到路由器，或者交叉网线连接到电脑

设置网络参数，网卡设备默认为eth0，使用 ifconfig 命令配置
