+
===Ethernet Connection===
===连接有线网络===
+
If a NanoPi NEO2 is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it is powered up. If it is not connected via Ethernet or its DHCP is not activated obtaining an IP will fail and system will hang on for about 15 to 60 seconds.In this case you can try obtaining an IP by using the following command:
NanoPi NEO2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">
 
<syntaxhighlight lang="bash">
 
dhclient eth0
 
dhclient eth0
 
</syntaxhighlight>
 
</syntaxhighlight>
  
===SSH登录===
+
===Login via SSH===
NEO2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NEO2。假设通过路由器查看到NEO2的IP地址为192.168.1.230,你可以在PC机上执行如下命令登录NEO2:
+
The NanoPi NEO2 doesn't have a video output interface. You can log into the board via SSH. In our test the IP address detected by our router was 192.168.1.230 and we ran the following command to log into the NanoPi NEO2:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
ssh root@192.168.1.230
 
ssh root@192.168.1.230
 
</syntaxhighlight>
 
</syntaxhighlight>
密码为fa。
+
The password is fa
  
===扩展TF卡文件系统===
+
===Extend TF Card's rootfs Section===
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:
+
When you boot Debian/UbuntuCore for the first time with your image card your OS will automatically resize the file system and this process takes a relatively long time.After your OS is fully loaded you can check the file system's size by using the following command:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
df -h
 
df -h
 
</syntaxhighlight>
 
</syntaxhighlight>
  
===连接USB WiFi===
+
===Connect USB WiFi to NEO2===
系统默认已经支持市面上众多常见的USB WiFi,想知道你的USB WiFi是否可用只需将其接在NEO2上即可,已测试过的USB WiFi型号如下:

NanoPi NEO2 上电启动并插入上USB WiFi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USB WiFi,如果出现“wlan0”,则证明USB WiFi已被识别到:
+
If you NanoPi NEO2 is connected to a USB WiFi and is powered up you can log into NEO2 and run the following command to check if the USB WiFi is recognized. If "wlan0" is listed it indicates your USB WiFi has been recognized:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
sudo ifconfig -a
 
sudo ifconfig -a
 
</syntaxhighlight>
 
</syntaxhighlight>
  
用vi打开文件 /etc/wpa_supplicant/wpa_supplicant.conf: <br />
+
Open this file "/etc/wpa_supplicant/wpa_supplicant.conf": <br />
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
 
sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
 
</syntaxhighlight>
 
</syntaxhighlight>
  
在文件末尾填入路由器信息如下所示:
+
Open the /etc/wpa_supplicant/wpa_supplicant.conf file and append the following lines:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
network={
 
network={
Line 253: Line 249:
 
}
 
}
 
</syntaxhighlight>
 
</syntaxhighlight>
其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。<br />
+
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.<br/>
保存退出后,执行以下命令即可连接WiFi: <br />
+
Save, exit and run the following commands to connect to your WiFi router:  
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
$ sudo ifdown wlan0
 
$ sudo ifdown wlan0
 
$ sudo ifup wlan0
 
$ sudo ifup wlan0
 
</syntaxhighlight>
 
</syntaxhighlight>
 
+
If your WiFi password has special characters or you don't want your password saved as plain text you can use "wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:  
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">
 
<syntaxhighlight lang="bash">
 
$ sudo wpa_passphrase YourWiFiESSID
 
$ sudo wpa_passphrase YourWiFiESSID
 
</syntaxhighlight>
 
</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。
+
Following the prompt type in your password and you will get a new password in the /etc/wpa_supplicant/wpa_supplicant.conf file. Now you can replace the existing password in the wlan0 file with the new one.
  
===连接USB摄像头模块(FA-CAM202)使用===
+
===Connect NanoPi NEO2 to USB Camera(FA-CAM202)===
 
[[File:USB-Camera-NanoPi-NEO2.png|frameless|500px|USB camera]]<br/>
 
[[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)/zh|Matrix - USB_Camera(FA-CAM202)]]
+
The FA-CAM202 is a 2M-pixel USB camera module.
启动系统,连接网络,以root用户登录终端并编译运行mjpg-streamer:
+
Boot your NEO2, connect NEO2 to the internet, log in the system as root, compile and run the mjpg-streamer utility:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
cd /root/mjpg-streamer
 
cd /root/mjpg-streamer
 +
apt-get install libjpeg62-dev
 
make
 
make
 
./start.sh
 
./start.sh
 
</syntaxhighlight>
 
</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:
+
The mjpg-streamer is an open source media server. After it is started successfully you will see the following messages:
 
<syntaxhighlight lang="bash">  
 
<syntaxhighlight lang="bash">  
 
  i: Using V4L2 device.: /dev/video0
 
  i: Using V4L2 device.: /dev/video0
Line 288: Line 284:
 
</syntaxhighlight>
 
</syntaxhighlight>
  
假设NEO2的IP地址为192.168.1.123,在PC的浏览器中输入 192.168.1.123:8080 就能浏览摄像头采集的画面了,效果如下:<br>
+
In our case our NEO2's IP address was 192.168.1.123. We typed "192.168.1.123:8080" on a browser, entered and we got the following screenshot:<br>
 
[[File:mjpg-streamer-cam500a.png|frameless|400px|mjpg-streamer-cam500a]] <br>
 
[[File:mjpg-streamer-cam500a.png|frameless|400px|mjpg-streamer-cam500a]] <br>
 +
<!---
 +
The mjpg-streamer uses libjpeg to soft-encode camera's input data. You can use ffmpeg to hard-encode data which greatly increases system's efficiency:
 +
<syntaxhighlight lang="bash">
 +
ffmpeg -t 30 -f v4l2 -channel 0 -video_size 1280x720 -i /dev/video0 -pix_fmt nv12 -r 30 -b:v 64k -c:v cedrus264 test.mp4
 +
</syntaxhighlight>
 +
By default it records a 30-second video. When you type "q" it will stop recording and the recorded video will be saved as a test.mp4 file.
 +

For more details refer to pcb file in dxf format

4 Get Started

4.1 Essentials You Need

Before starting to use your NanoPi NEO2 get the following items ready

  • NanoPi NEO2
  • microSD Card/TFCard: Class 10 or Above, minimum 8GB SDHC
  • microUSB power. A 5V/2A power is a must
  • A Host computer running Ubuntu 14.04 64 bit system

4.2 TF Cards We Tested

To make your NanoPi NEO2 boot and run fast we highly recommend you use a Class10 8GB SDHC TF card or a better one. The following cards are what we used in all our test cases presented here:

  • SanDisk TF 8G Class10 Micro/SD TF card:

SanDisk MicroSD 8G

  • SanDisk TF128G MicroSDXC TF 128G Class10 48MB/S:

SanDisk MicroSD 128G

  • 川宇 8G C10 High Speed class10 micro SD card:

chuanyu MicroSD 8G

4.3 Make an Installation TF Card

4.3.1 Get Image File

Get the following files from download link to download image files (under the officail-ROMs directory) and the flashing utility(under the tools directory):

Image Files:
nanopi-neo2-ubuntu-core-qte-sd4g.img.zip Ubuntu-Core with Qt-Embedded Image File
Flash Utility:
win32diskimager.rar Windows utility. Under Linux users can use "dd"

4.3.2 Make Ubuntu-Core with Qt-Embedded Image Card

Extract the nanopi-neo2-ubuntu-core-qte-sd4g.img.zip and win32diskimager.rar files. Insert a TF card(at least 8G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your TF card's drive, the wanted image file and click on "write" to start flashing the TF card. After this writing process is done insert this card into your NanoPi NEO2's TF card slot and power on (with a 5V/2A power source). If the blue LED is blinking this indicates your NanoPi NEO2 has successfully booted.

5 Work with Ubuntu-Core with Qt-Embedded

5.1 Run Ubuntu-Core with Qt-Embedded

  • 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 NanoPi NEO2 to a PC via the PSU-ONECOM and you can power on your NEO2 from either the PSU-ONECOM or the board's MicroUSB:

PSU-ONECOM-NEO2

  • Ubuntu-Core's 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

5.2 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

5.3 Ethernet Connection

If a NanoPi NEO2 is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it is powered up. If it is not connected via Ethernet or its DHCP is not activated obtaining an IP will fail and system will hang on for about 15 to 60 seconds.In this case you can try obtaining an IP by using the following command:

dhclient eth0

5.4 Login via SSH

The NanoPi NEO2 doesn't have a video output interface. You can log into the board via SSH. In our test the IP address detected by our router was 192.168.1.230 and we ran the following command to log into the NanoPi NEO2:

ssh root@192.168.1.230

5.5 Extend TF Card's rootfs Section

When you boot Debian/UbuntuCore for the first time with your image card your OS will automatically resize the file system and this process takes a relatively long time.After your OS is fully loaded you can check the file system's size by using the following command:

df -h

5.6 Connect USB WiFi to NEO2

Our system has support for popular USB WiFi drivers. Many USB WiFi modules are plug and play with our system. Here is a list of models we tested;

Number Model
1 RTL8188CUS 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 NetGear, Inc. WG111v3 54 Mbps Wireless [realtek RTL8187B]

If you NanoPi NEO2 is connected to a USB WiFi and is powered up you can log into NEO2 and run the following command to check if the USB WiFi is recognized. If "wlan0" is listed it indicates your USB WiFi has been recognized:

sudo ifconfig -a

Open this file "/etc/wpa_supplicant/wpa_supplicant.conf":

sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

Open the /etc/wpa_supplicant/wpa_supplicant.conf file and append the following lines:

network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}

The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.
Save, exit and run the following commands to connect to your WiFi router:

$ sudo ifdown wlan0
$ sudo ifup wlan0

If your WiFi password has special characters or you don't want your password saved as plain text you can use "wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:

$ sudo wpa_passphrase YourWiFiESSID

Following the prompt type in your password and you will get a new password in the /etc/wpa_supplicant/wpa_supplicant.conf file. Now you can replace the existing password in the wlan0 file with the new one.

5.7 Connect NanoPi NEO2 to USB Camera(FA-CAM202)

6 Make Your Own Ubuntu-Core with Qt-Embedded

6.1 Preparations

Visit this link download link and enter the "sources/nanopi-H5-bsp" directory and download all the source code.Use the 7-zip utility to extract it and a lichee directory and an Android directory will be generated.You can check that by running the following command:

ls ./
lichee

Or you can get it from our github:

git clone https://github.com/friendlyarm/h5_lichee.git lichee

Note: "lichee" is the project name named by Allwinner for its CPU's source code which contains the source code of U-boot, Linux kernel and various scripts.

6.2 Install Cross Compiler

Visit this site download link, enter the "toolchain" directory, download the cross compiler "gcc-linaro-arm-4.6.3.tar.xz" and "gcc-linaro-aarch64.tar.xz" and copy them to the "lichee/brandy/toochain/" directory.
"gcc-linaro-arm-4.6.3.tar.xz"is for compiling u-boot and "gcc-linaro-aarch64.tar.xz" is for compiling Linux kernel.

6.3 Compile lichee Source Code

Compilation of the H5's BSP source code must be done under a PC running a 64-bit Linux.The following cases were tested on Ubuntu-14.04 LTS-64bit:

sudo apt-get install gawk git gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
libgl1-mesa-dev g++-multilib mingw32 tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386

Enter the lichee directory and run the following command to compile the whole package:

cd lichee/fa_tools
./build.sh -b nanopi-neo2 -p linux -t all

After this compilation succeeds a u-boot, Linux kernel and kernel modules will be generated.
Note: the lichee directory contains cross-compilers we have setup. When the build.sh script runs it will automatically call these cross-compilers.

The following commands can be used to update the u-boot on an installation TF card:

cd lichee/fa_tools/
./fuse.sh -d /dev/sdx -p linux -t u-boot

Note: you need to replace "/dev/sdx" with the device name in your system.
The boot.img and kernel modules are under the "linux-3.10/output" directory. You can copy the new boot.img file to your TF card's boot section.

6.4 Compile U-boot

You can run the following commands to compile u-boot individually:

cd lichee/fa_tools/
./build.sh -b nanopi-neo2 -p linux -t u-boot

6.5 Compile Linux Kernel

You can run the following commands to compile Linux kernel individually:

cd lichee/fa_tools/
./build.sh -b nanopi-neo2 -p linux -t kernel

The boot.img and kernel modules are under the "linux-3.10/output" directory. You can copy the new boot.img file to your TF card's boot section.

6.6 Clean Source Code

cd lichee/fa_tools/
./build.sh -b nanopi-neo2 -p linux -t clean
