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
- Login via Serial Port
When you do kernel development you'd better get a serial communication board. After you connect your board to a serial communication board you will be able to do development work from a commandline utility.
Here is a hardware setup:
After you connect your board to a serial communication board (e.g. FriendlyElec's serial communication board) you can power the whole system from either the DC port on the serial communication board or the MicroUSB port(if there is one) on your board:
or you can use a USB to serial board and power on the whole system at the MicroUSB port with a 5V/2A power.
By default you will login as root without a password. You can use "passwd" to set a password for root.
On first boot the system will automatically extend the file system on the TF card to the max capacity:
Please wait for this to be done.
- Login via SSH
- Login via Web
You can login OpenWrt via a LuCI Web page.
By default you will login as root without a password, just click on "Login" to login.
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 Check System Status
- Check CPU Temperature & Frequency via Commandline
$ 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
These messages mean that there are four CPU cores working online simultaneously. Each core's temperature is 26.5 degrees in Celsius, the scheduling policy is on-demand and the working frequency is 624MHz. You can set the frequency by running the following command:
$ 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.
- Check System Status on OpenWrt-LuCI Web Page
After open the OpenWrt-LuCI page, go to "Statistics ---> Graphs" and you will see various system statistics e.g.:
1) System Load:
2) RAM:
3) CPU Temperature:
All the statistics listed on the Statistics page are presented by the luci-app-statistics package which uses the Collectd utility to collect data and presents them with the RRDtool utility.
If you want to get more statistics you can install other collectd-mod-* packages.
All collectd-mod-* packages use the same configuration file: /etc/config/luci_statistics.

1.5 Check Network->Interfaces Configurations
- After open the OpenWrt-LuCI page, go to "Network" ---> "Interfaces" and you will see the current network's configurations:
- All the configurations listed on the Network->Interfaces page are stored in the "/etc/config/network" file.
1.6 USB WiFi
Currently the NanoPi NEO2 Black only works with a RTL8821CU USB WiFi dongle, plug and play. After this module is connected to the board it will by default work under AP mode and the hotspot's name is "rtl8821cu-mac address" and the password is "password";
1.7 Huawei's WiFi 2 mini(E8372H-155) Module
After this module is connected to the board it will be plug and play. The hotspot's name is "HUAWEI-8DA5". You can connect a device to the internet by connecting to this hotspot.
