FriendlyElec's OpenWrt uses the triggerhappy utility to configure buttons.

本OpenWrt系统使用软件包triggerhappy配置按键的功能，默认的配置为按下按键就会触发系统执行reboot操作。

The triggerhappy utility uses the "/etc/triggerhappy/triggers.d/example.conf" configuration file.

如果系统发生了异常需要重启，建议使用该按键触发软件reboot，这样可以有效地避免由于断电而造成的文件系统损坏的问题。<br>

triggerhappy对应的配置文件为/etc/triggerhappy/triggers.d/example.conf。

1 Work with OpenWrt

1.1 Introduction

OpenWrt is a highly extensible GNU/Linux distribution for embedded devices.Unlike many other distributions for routers, OpenWrt is built from the ground up to be a full-featured, easily modifiable operating system for embedded devices. In practice, this means that you can have all the features you need with none of the bloat, powered by a modern Linux kernel. For more details you can refer to:OpenWrt Website.

1.2 System Login

  • 串口登录

如果您需要进行内核开发，最好选购一个串口配件，连接了串口，则可以通过串口终端对开发板进行操作。
使用串口模块能有效地提升开发效率，以下是串口模块的连接方法：
接上串口后，您可以选择从串口模块的DC口或者从MicroUSB口 (如果有) 进行供电。

也可以使用USB转串口模块调试，请注意需要使用5V/2A电源给开发板MicroUSB供电。

默认会以 root 用户自动登录，并且没有设置root用户的密码，你可以使用 passwd 命令来设置 root 用户的密码。
op_login
第一次运行系统时，系统会自动拓展TF卡上文件系统分区到最大可用空间：
resize_rootfs_userdata
请耐心等待文件系统扩展完成。

  • SSH登录


  • Web登录

OpenWrt系统支持通过LuCI Web界面进行访问和配置。

默认用户名为root，无需密码，直接点击"Login"按键即可登录。

1.3 Manage Software Packages

OpenWrt has a package management utility: opkg. You can get its details by running the following command: 

$ opkg
Package Manipulation:
        update                  Update list of available packages
        upgrade <pkgs>          Upgrade packages
        install <pkgs>          Install package(s)
        configure <pkgs>        Configure unpacked package(s)
        remove <pkgs|regexp>    Remove package(s)
        flag <flag> <pkgs>      Flag package(s)
         <flag>=hold|noprune|user|ok|installed|unpacked (one per invocation)
 
Informational Commands:
        list                    List available packages
        list-installed          List installed packages
        list-upgradable         List installed and upgradable packages
        list-changed-conffiles  List user modified configuration files
        files <pkg>             List files belonging to <pkg>
        search <file|regexp>    List package providing <file>
        find <regexp>           List packages whose name or description matches <regexp>
        info [pkg|regexp]       Display all info for <pkg>
        status [pkg|regexp]     Display all status for <pkg>
        download <pkg>          Download <pkg> to current directory
...

These are just part of the manual. Here are some popular opkg commands.

  • Update Package List

Before you install a package you'd better update the package list: 

$ opkg update
  • Check Available Packages
$ opkg list

At the time of writing there are 3241 packages available.

  • Check Installed Packages:
$ opkg list-installed

At the time of writing 124 packages have been installed.

  • Install/Delete Packages:
$ opkg install <pkgs>
$ opkg remove <pkgs>
  • Check Files Contained in Installed Packages:
$ opkg files <pkg>
  • Install Chinese Language Package for LuCI
$ opkg install luci-i18n-base-zh-cn
  • Check Changed Files:
$ opkg list-changed-conffiles

1.4 查看系统状态

  • 命令行查看CPU温度和频率
$ cpu_freq 
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU1 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU2 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU3 online=1 temp=26548C governor=ondemand freq=624000KHz

上述信息表示当前有4个CPU核在线, 温度均约为26.5摄氏度, 运行的策略均为根据需求来决定运行频率, 当前的运行频率均为624MHz，设置频率的命令如下： 

$ cpu_freq -s 1008000
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU1 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU2 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU3 online=1 temp=36702C governor=userspace freq=1008000KHz

These messages mean four CPU cores are working online. Each core's temperature is 26.5 degrees. Each core's governor is on demand and the frequency is 480 MHz.

  • OpenWrt-LuCI Web界面查看系统状态

登录OpenWrt-LuCI界面后，点击顶部的 Statistics ---> Graphs，可以查看系统的各种软硬件状态信息(即statistics)，例如:
1) System Load:
statistics_system_load
2) RAM:
statistics_memory
3) CPU Temperature:
statistics_thermal
Statistics界面对应软件包luci-app-statistics，luci-app-statistics软件包用Collectd工具收集状态数据并且用RRDtool工具将数据渲染为图表。
你可以通过安装额外的collectd-mod-*软件包去使能更多的statistics. All collectd-mod-* packages use the same configuration file: /etc/config/luci_statistics.

1.5 查看Network->Interfaces的配置

  • 登录OpenWrt-LuCI界面后，点击顶部的 Network ---> Interfaces ，可以查看当前的网络设置:
  • Network->Interfaces界面的配置保存在/etc/config/network中。
