[[File:PSU-ONECOM-NEO-Plus2.jpg|frameless|400px|PSU-ONECOM-NEO_Plus2]]<br>
+
也可以使用USB转串口模块调试,请注意需要使用5V/2A电源从NanoPi NEO Plus2的MicroUSB口给NEO Plus2供电:<br>
+
[[File:USB2UART-NEO-Plus2.jpg|frameless|400px|USB2UART-NEO-Plus2]]
+
* Ubuntu-Core默认帐户:
+
普通用户:
+
    用户名: pi
+
    密码: pi
+
 
+
Root用户:
+
    用户名: root
+
    密码: fa
+
 
+
默认会以 pi 用户自动登录,你可以使用 sudo npi-config 命令取消自动登录。
+
 
+
* 更新软件包:
+
<syntaxhighlight lang="bash">
+
sudo apt-get update
+
</syntaxhighlight>
+
 
+
===使用npi-config配置系统===
+
npi-config是一个命令行下的系统配置工具,可以对系统进行一些初始化的配置,可配置的项目包括:用户密码、系统语言、时区、Hostname、SSH开关、自动登录选项等,在命令行执行以下命令即可进入:
+
<syntaxhighlight lang="bash">
+
sudo npi-config
+
</syntaxhighlight>
+
npi-config的显示界面如下所示:<br />
+
[[File:npi-config.jpg|frameless|500px|npi-config]]<br />
+
 
+
 
+
===连接有线网络===
+
NanoPi NEO Plus2在加电开机前如果已正确的连接网线,则系统启动时会自动获取IP地址,如果没有连接网线、没有DHCP服务或是其它网络问题,则会导致获取IP地址失败,同时系统启动会因此等待约15~60秒的时间。
+
手动获取IP地址
+
<syntaxhighlight lang="bash">
+
dhclient eth0
+
</syntaxhighlight>
+
 
+
===SSH登录===
+
NanoPi NEO Plus2没有任何图形界面输出的接口,如果你没有串口模块,可以通过SSH协议登录NanoPi NEO Plus2。假设通过路由器查看到NanoPi NEO Plus2的IP地址为192.168.1.230,你可以在PC机上执行如下命令登录NanoPi NEO Plus2:
+
<syntaxhighlight lang="bash">
+
ssh root@192.168.1.230
+
</syntaxhighlight>
+
密码为fa。
+
 
+
===扩展TF卡文件系统===
+
第一次启动系统时,系统会自动扩展文件系统分区,请耐心等待,TF卡的容量越大,需要等待的时间越长,进入系统后执行下列命令查看文件系统分区大小:
+
<syntaxhighlight lang="bash">
+
df -h
+
</syntaxhighlight>
+
 
+
===连接无线网络===
+
NanoPi NEO Plus使用无线网络或者蓝牙的时候,需要接上天线使用。以下是 NEO Plus2连接使用IPX天线的图片:
+
 
+
NanoPi NEO Plus2 上电启动后,通过串口登录到系统,敲入以下命令可以查看到系统是否识别到 WiFi,如果出现“wlan0”,则证明WiFi已被识别到:
+
<syntaxhighlight lang="bash">
+
sudo ifconfig -a
+
</syntaxhighlight>
+
 
+
用vi打开文件 /etc/wpa_supplicant/wpa_supplicant.conf: <br />
+
<syntaxhighlight lang="bash">
+
sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
+
</syntaxhighlight>
+
 
+
在文件末尾填入路由器信息如下所示:
+
<syntaxhighlight lang="bash">
+
network={
+
        ssid="YourWiFiESSID"
+
        psk="YourWiFiPassword"
+
}
+
</syntaxhighlight>
+
其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。<br />
+
保存退出后,执行以下命令即可连接WiFi: <br />
+
<syntaxhighlight lang="bash">
+
$ sudo ifdown wlan0
+
$ sudo ifup wlan0
+
</syntaxhighlight>
+
 
+
如果你的WiFi密码中有特殊字符,或者你不希望明文存放密码,你可以使用wpa_passphrase命令为WiFi密码生成一个密钥(psk),用密钥来代替密码 ,在命令行下,可输入以下命令生成密钥: <br />
+
<syntaxhighlight lang="bash">
+
$ sudo wpa_passphrase YourWiFiESSID
+
</syntaxhighlight>
+
在提示输入密码时,输入你的WiFi密码,再打开 /etc/wpa_supplicant/wpa_supplicant.conf 文件你会发现密钥已经被更新,你可以删除明文的密码了。
+
 
+
===连接USB摄像头模块(FA-CAM202)使用===
+
[[File:USB-Camera-NanoPi-NEO2.png|frameless|500px|USB camera]]<br/>
+
FA-CAM202是一款200万像素的USB摄像头模块,参考维基[[Matrix - USB_Camera(FA-CAM202)|Matrix - USB_Camera(FA-CAM202)]]
+
启动系统,连接网络,以root用户登录终端并编译运行mjpg-streamer:
+
<syntaxhighlight lang="bash">
+
cd /root/mjpg-streamer
+
make
+
./start.sh
+
</syntaxhighlight>
+
mjpg-streamer是一个开源的网络视频流服务器,在板子上成功运行mjpg-streamer后会打印下列信息:
+
<syntaxhighlight lang="bash">
+
i: Using V4L2 device.: /dev/video0
+
i: Desired Resolution: 1280 x 720
+
i: Frames Per Second.: 30
+
i: Format............: YUV

7 Work with FriendlyCore

7.1 Introduction

FriendlyCore is a light Linux system without X-windows, based on ubuntu core, It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

Besides the regular Ubuntu Core's features FriendlyCore has the following additional features:

  • it integrates Qt4.8;
  • it integrates NetworkManager;
  • it has bluez and Bluetooth related packages;
  • it has alsa packages;
  • it has npi-config;
  • it has RPiGPIO, a Python GPIO module;
  • it has some Python/C demo in /root/ directory;
  • it enables 512M-swap partition;

7.2 System Login

  • If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
  • If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will

allow you to operate the board via a serial terminal.Here is a setup where we connect a board to a PC via the PSU-ONECOM and you can power on your board from either the PSU-ONECOM or its MicroUSB: PSU-ONECOM-NEO-Plus2.jpg
You can use a USB to Serial conversion board too.
Make sure you use a 5V/2A power to power your board from its MicroUSB port:
USB2UART-NEO-Plus2.jpg

  • FriendlyCore User Accounts:

Non-root User:

   User Name: pi
   Password: pi

Root:

   User Name: root
   Password: fa

The system is automatically logged in as "pi". You can do "sudo npi-config" to disable auto login.

  • Update packages
$ sudo apt-get update

7.3 Configure System with npi-config

The npi-config is a commandline utility which can be used to initialize system configurations such as user password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following command to run this utility.

$ sudo npi-config

Here is how npi-config's GUI looks like:
npi-config

7.4 Develop Qt Application

Please refer to: How to Build and Install Qt Application for FriendlyELEC Boards

7.5 Setup Program to AutoRun

You can setup a program to autorun on system boot with npi-config:

sudo npi-config

Go to Boot Options -> Autologin -> Qt/Embedded, select Enable and reboot.

7.6 Extend TF Card's Section

When FriendlyCore is loaded the TF card's section will be automatically extended.You can check the section's size by running the following command:

$ df -h

7.7 Transfer files using Bluetooth

Take the example of transferring files to the mobile phone. First, set your mobile phone Bluetooth to detectable status, then execute the following command to start Bluetooth search.:

hcitool scan


Search results look like:

Scanning ...
    2C:8A:72:1D:46:02   HTC6525LVW

This means that a mobile phone named HTC6525LVW is searched. We write down the MAC address in front of the phone name, and then use the sdptool command to view the Bluetooth service supported by the phone:

sdptool browser 2C:8A:72:1D:46:02

Note: Please replace the MAC address in the above command with the actual Bluetooth MAC address of the mobile phone.
This command will detail the protocols supported by Bluetooth for mobile phones. What we need to care about is a file transfer service called OBEX Object Push. Take the HTC6525LVW mobile phone as an example. The results are as follows:

Service Name: OBEX Object Push
Service RecHandle: 0x1000b
Service Class ID List:
  "OBEX Object Push" (0x1105)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 12
  "OBEX" (0x0008)
Profile Descriptor List:
  "OBEX Object Push" (0x1105)
    Version: 0x0100

As can be seen from the above information, the channel used by the OBEX Object Push service of this mobile phone is 12, we need to pass it to the obexftp command, and finally the command to initiate the file transfer request is as follows:

obexftp --nopath --noconn --uuid none --bluetooth -b 2C:8A:72:1D:46:02 -B 12 -put example.jpg

Note: Please replace the MAC address, channel and file name in the above command with the actual one.

After executing the above commands, please pay attention to the screen of the mobile phone. The mobile phone will pop up a prompt for pairing and receiving files. After confirming, the file transfer will start.

Bluetooth FAQ:
1) Bluetooth device not found on the development board, try to open Bluetooth with the following command:

rfkill unblock 0

2) Prompt can not find the relevant command, you can try to install related software with the following command:

apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push

7.8 WiFi

For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:

Index Model
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601
6 5G USB WiFi RTL8821CU
7 5G USB WiFi RTL8812AU

You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:

  • Change to root
$ su root
  • Check device list
$ nmcli dev

Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.

  • Start WiFi
$ nmcli r wifi on
  • Scan Surrounding WiFi Sources
$ nmcli dev wifi
  • Connect to a WiFi Source
$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.

For more details about NetworkManager refer to this link: Use NetworkManager to configure network settings

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:

$ apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.

7.9 Setup Wi-Fi Hotspot

Run the following command to enter AP mode:

$ su root
$ turn-wifi-into-apmode yes

You will be prompted to type your WiFi hotspot's name and password and then proceed with default prompts.

TERM=linux toilet -f standard -F metal HELLO

7.14 Modify timezone

For exampe, change to Shanghai timezone:

sudo rm /etc/localtime
sudo ln -ls /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

7.15 Set Audio Device

If your system has multiple audio devices such as HDMI-Audio, 3.5mm audio jack and I2S-Codec you can set system's default audio device by running the following commands.

  • After your board is booted run the following commands to install alsa packages:
$ apt-get update
$ apt-get install libasound2
$ apt-get install alsa-base
$ apt-get install alsa-utils
  • After installation is done you can list all the audio devices by running the following command. Here is a similar list you may see after you run the command:
$ aplay -l
card 0: HDMI
card 1: 3.5mm codec
card 2: I2S codec

"card 0" is HDMI-Audio, "card 1" is 3.5mm audio jack and "card 2" is I2S-Codec. You can set default audio device to HDMI-Audio by changing the "/etc/asound.conf" file as follows:

pcm.!default {
    type hw
    card 0
    device 0
}
 
ctl.!default {
    type hw
    card 0
}

If you change "card 0" to "card 1" the 3.5mm audio jack will be set to the default device.
Copy a .wav file to your board and test it by running the following command:

$ aplay /root/Music/test.wav

You will hear sounds from system's default audio device.
If you are using H3/H5/H2+ series board with mainline kernel, the easier way is using npi-config



7.16 Connect to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera. You can refer to <Connect DVP Camera (CAM500B) to Board> on how to connect a USB camera to a board.
You need to change the start.sh script and make sure it uses a correct /dev/videoX node. You can check your FA-CAM202's node by running the following commands:

$ apt-get install v4l-utils
$ v4l2-ctl -d /dev/video1 -D
Driver Info (not using libv4l2):
        Driver name   : uvcvideo

8 Work with OpenWrt

8.1 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.

8.2 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:
PSU-ONECOM-NEO-Plus2.jpg

or you can use a USB to serial board and power on the whole system at the MicroUSB port with a 5V/2A power:
USB2UART-NEO-Plus2.jpg

By default you will login as root without a password. You can use "passwd" to set a password for root.
op_login
On first boot the system will automatically extend the file system on the TF card to the max capacity:
resize_rootfs_userdata
Please wait for this to be done.

  • Login via SSH

In FriendlyElec's OpenWrt system the Ethernet(eth0) is configured as WAN.
Before power on your board make sure your board is connected to a master router's LAN with an Ethernet cable and the eth0 will be assigned an IP address by DHCP.
For example, if your eth0 is assigned an IP address 192.168.1.163 you can login with SSH by running the following command:

$ ssh root@192.168.1.163

You can login without a password.

  • Login via Web

You can login OpenWrt via a LuCI Web page.
After you go through all the steps in <Login via SSH> and get an IP address e.g. 192.168.1.163 for the Ethernet connection, type this IP address in a browser's address bar and you will be able to login OpenWrt-LuCI:
R1-OpenWrt-LuCI
By default you will login as root without a password, just click on "Login" to login.

8.3 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

8.4 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

        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:
statistics_system_load
2) RAM:
statistics_memory
3) CPU Temperature:
statistics_thermal
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.

8.5 Check Network->Interfaces Configurations

  • After open the OpenWrt-LuCI page, go to "Network" ---> "Interfaces" and you will see the current network's configurations:

op_interface_eth0_br

  • All the configurations listed on the Network->Interfaces page are stored in the "/etc/config/network" file.

8.6 Check Netwrok->Wireless Configurations

  • After open the OpenWrt-LuCI page, go to Network ---> Wireless and you will see the WiFi hotspot's configurations:

op_wireless
A default WiFi AP's hotspot name looks like "OpenWrt-10:d0:7a:de:3d:92". It doesn't have a password. You can connect your smart phone to it and browse the internet.

  • All the configurations listed on the Network->Wireless page are stored in the "/etc/config/wireless" file.
