linux-zero-5.2.y 启动后没有usb0

linux-xc · 2022-07-01 14:31:59

烧录网友提供的.dd镜像可以找到usb0设备，联网，但是自己重新编译的内核更换原来的内核后，就无法找到usb0了。

原镜像：lichee_zero-mindb_alpha.dd

下面是内核启动信息：

root@LicheePi:~# dmesg | grep Failed

dmesg打印表明无法加载autofs4、ipv6模块，应该是找不到usb0导致的

以下的ifconfig打印信息：

root@LicheePi:~# ifconfig -a
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

然后根据网上办法配置内核，仍无法找到 usb0

在内核编译阶段，通过编译模块/安装模块操作，成功在zero上打印出usb0

尝试 ifconfig usb0 192.168.2.140
成功设置ip，但无法ping通任何地址

尝试 dhclient usb0
终端阻塞，无法进行操作，只能退出

下面是dmseg

查到一种办法：设置网关
来源：https://blog.csdn.net/yanhe156/article/details/79664166

route add default gw 192.168.2.1

成功设置网关，但依然无法ping通

新现象，OTG所连USB转网口闪灯

找到办法了，完全查看内核配置的各个选项后，发现内核配置没有勾选USB的网络相关驱动。
不知道官方为什么没有默认选择这部分驱动？

因此，我直接将所有相关驱动都加载进去了
应该是某个驱动实现了，但暂时并不清楚，有待前辈指点。

具体方法，在内核源码目录输入 make ARCH=arm menuconfig

Device Drivers  --->  
    [*] Network device support  ---> 
         <*>   USB Network Adapters  --->
                子选项全部勾选,子选项的子选项默认即可

此外，还可以自行搜索以下配置打勾（根据自身需要打勾）（按键盘 / 键可以搜索）

DNS Resolver support

Generic failover module

Network block device support

USB CATC NetMate-based Ethernet device support

最后，开机自动联网，无需任何设置，打印如下：
