V3S-Zero 网络篇章 Linux5.2
板子上的网口可不能白占着空间
进入主题
开启网口需要 修改Uboot Kernel 文件系统 缺一不可
5.2的内核对NET网络已经支持 所以修改较少
以下是基于TF卡试验的(同等也可以修改在Flash版本中)
Uboot
下载主线的Uboot源码
v3s-current
https://github.com/Lichee-Pi/u-boot.git
修改如下
修改include/configs/sun8i.h
/*
* Include common sunxi configuration where most the settings are
*/
/*一定要放下面*/
#include 修改Dts文件
sun8i-v3s.dtsi 修改如下
soc {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges;
/*添加syscon*/
syscon: syscon@01c00000 {
compatible = "allwinner,sun8i-h3-syscon","syscon";
reg = <0x01c00000 0x34>;
};
mmc0: mmc@01c0f000 {
compatible = "allwinner,sun7i-a20-mmc";
reg = <0x01c0f000 0x1000>;
clocks = <&ccu CLK_BUS_MMC0>,
<&ccu CLK_MMC0>,
<&ccu CLK_MMC0_OUTPUT>,
<&ccu CLK_MMC0_SAMPLE>;
clock-names = "ahb",
"mmc",
"output",
"sample";
resets = <&ccu RST_BUS_MMC0>;
reset-names = "ahb";
interrupts = <GIC_SPI 60 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
#address-cells = <1>;
#size-cells = <0>;
};
pio: pinctrl@01c20800 {
compatible = "allwinner,sun8i-v3s-pinctrl";
reg = <0x01c20800 0x400>;
interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ccu CLK_BUS_PIO>, <&osc24M>, <&osc32k>;
clock-names = "apb", "hosc", "losc";
gpio-controller;
#gpio-cells = <3>;
interrupt-controller;
#interrupt-cells = <3>;
/*Pin添加RMII的描述*/
emac_rgmii_pins: emac0@0 {
allwinner,pins = "PD0", "PD1", "PD2", "PD3",
"PD4", "PD5", "PD7",
"PD8", "PD9", "PD10",
"PD12", "PD13", "PD15",
"PD16", "PD17";
allwinner,function = "emac";
allwinner,drive = <SUN4I_PINCTRL_40_MA>;
allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;
};
uart0_pins_a: uart0@0 {
pins = "PB8", "PB9";
function = "uart0";
bias-pull-up;
};
gic: interrupt-controller@01c81000 {
compatible = "arm,cortex-a7-gic", "arm,cortex-a15-gic";
reg = <0x01c81000 0x1000>,
<0x01c82000 0x1000>,
<0x01c84000 0x2000>,
<0x01c86000 0x2000>;
interrupt-controller;
#interrupt-cells = <3>;
interrupts = <GIC_PPI 9 (GIC_CPU_MASK_SIMPLE(4) | IRQ_TYPE_LEVEL_HIGH)>;
};
/*添加EMAC描述*/
emac: ethernet@1c30000 {
compatible = "allwinner,sun8i-h3-emac";
reg = <0x01c30000 0x104>, <0x01c00030 0x4>;
reg-names = "emac", "syscon";
interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
resets = <&ccu RST_BUS_EMAC>, <&ccu RST_BUS_EPHY>;
reset-names = "ahb", "ephy";
clocks = <&ccu CLK_BUS_EMAC>, <&ccu CLK_BUS_EPHY>;
clock-names = "ahb", "ephy";
#address-cells = <1>;
#size-cells = <0>;
status = "disabled";
};
};
sun8i-v3s-licheepi-zero.dts 修改如下
model = "Lichee Pi Zero";
compatible = "licheepi,licheepi-zero", "allwinner,sun8i-v3s";
aliases {
serial0 = &uart0;
ethernet0 = &emac;
spi0 = &spi0;
};
chosen {
stdout-path = "serial0:115200n8";
};
添加emac
&emac {
phy = <&phy0>;
phy-mode = "mii";
allwinner,use-internal-phy;
allwinner,leds-active-low;
status = "okay";
phy0: ethernet-phy@0 {
reg = <1>;
};
};
Uboot设备树修改如上即可
进入Uboot的menuconfig
修改
Kernel
修改 设备树文件
sun8i-v3s-licheepi-zero.dts
aliases {
serial0 = &uart0;
ethernet0 = &emac;
};
&emac {
phy-handle = <&int_mii_phy>;
phy-mode = "mii";
allwinner,leds-active-low;
status = "okay";
};
menuconfig 修改
文件系统
文件系统制作（Buildroot） 可以参考
https://blog.csdn.net/weixin_44205779/article/details/107330375
制作好的文件系统 需要修改Net相关描述
/etc/network/interfaces 下
添加
auto eth0
iface eth0 inet static
address 192.168.11.188
netmask 255.255.255.0
gateway 192.168.11.1
对应的PC主机
我用的Windows
需要关闭防火墙 或者改出入站规则
不然ping 不上
改完之后的效果如下：
后面就可以愉快的使用网络了
