elf2的ubuntu系统的wifi配网

ELF2开发板的ubuntu系统的ax200 wifi配网

图1 开发板实物图

首先需要你需要烧写ubuntu系统，可以按照前文的基本环境搭建配置，完成ubuntu系统的烧录，有两种方式：方式一是将buildroot系统的/usr/lib/modules下面文件夹复制到ubuntu系统对应目录；方式二是编译rootfs根文件系统烧录到开发板。博主采用的是方法一，方法二可以具体看官方文档。

博主采用的方法（推荐使用，如果只是为了联网）

所需要的文件链接：https://download.csdn.net/download/weixin_44404482/90639829
该链接文件包含5.10.209.tar.bz2和cmddemo_wifi.sh。
登录开发板（root用户密码是root，elf用户是elf），传输文件到开发板（如果您未搭建ssh环境可以参考基本环境搭建，通过ssh将文件传输到开发板，或者通过u盘）

博主是在电脑上解压后再压缩成zip，使用unzip命令进行解压，因为bz2格式开发板没有命令解压

root@elf2-desktop:/home/elf/Desktop# ls
5.10.209  5.10.209.tar.bz2  5.10.209.zip  all_modules.tar.gz  cmddemo_wifi.zip  sh_my
root@elf2-desktop:/home/elf/Desktop# ls
5.10.209  5.10.209.tar.bz2  5.10.209.zip  all_modules.tar.gz  cmddemo_wifi.zip  sh_my
root@elf2-desktop:/home/elf/Desktop# ls 5.10.209

碰到的很弟弟的问题：我理解是把5.10.209文件内容复制到/usr/lib/modules,然后重启reboot后，使用lsmod命令并没有加载驱动，所以是要把5.10.209文件内容包含文件夹复制到/usr/lib/modules，重启后，执行如下：

root@elf2-desktop:~# lsmod
Module                  Size  Used by
iwlmvm                331776  0
iwlwifi               286720  1 iwlmvm
btusb                  57344  0
btrtl                  24576  1 btusb
btbcm                  24576  1 btusb
btintel                28672  1 btusb

sh脚本的内容其实就是调用了nmtui的

#!/bin/bash

ssid=""
password=""

while getopts "s:p:" opt; do
  case $opt in
    s)
      ssid="$OPTARG"
      ;;
    p)
      password="$OPTARG"
      ;;
    \?)
      echo "eg: $0 -s SSID -p password"
      exit 1
      ;;
  esac
done

if [ -z "$ssid" ] || [ -z "$password" ]; then
  echo "SSID and password is need."
  exit 1
fi

nmcli dev wifi connect "$ssid" password "$password"

我们连接网络，使用nmtui命令，选择第二个，输入密码后

能够看到已经成功连接上网络了。（或者使用命令拨号命令 ./cmddemo_wifi.sh -s SSID -p password）
