===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:
+
===连接有线网络===
 +
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>
  
===Login via SSH===
+
===SSH登录===
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:
+
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:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
ssh root@192.168.1.230
 
ssh root@192.168.1.230
 
</syntaxhighlight>
 
</syntaxhighlight>
The password is fa
+
密码为fa。
  
===Extend TF Card's rootfs Section===
+
===扩展TF卡文件系统===
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:
+
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">
 
<syntaxhighlight lang="bash">

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:
+
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:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
sudo ifconfig -a
 
sudo ifconfig -a
 
</syntaxhighlight>
 
</syntaxhighlight>
  
Open this file "/etc/wpa_supplicant/wpa_supplicant.conf": <br />
+
用vi打开文件 /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>
  
Open the /etc/wpa_supplicant/wpa_supplicant.conf file and append the following lines:
+
在文件末尾填入路由器信息如下所示:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
network={
 
network={
Line 249: Line 253:
 
}
 
}
 
</syntaxhighlight>
 
</syntaxhighlight>
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.<br/>
+
其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。<br />
Save, exit and run the following commands to connect to your WiFi router:  
+
保存退出后,执行以下命令即可连接WiFi: <br />
 
<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>
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.
+
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。
  
===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/>
The FA-CAM202 is a 2M-pixel USB camera module.
+
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)]]
Boot your NEO2, connect NEO2 to the internet, log in the system as root, compile and run the mjpg-streamer utility:
+
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">
 
<syntaxhighlight lang="bash">
 
cd /root/mjpg-streamer
 
cd /root/mjpg-streamer
apt-get install libjpeg62-dev
 
 
make
 
make
 
./start.sh
 
./start.sh
 
</syntaxhighlight>
 
</syntaxhighlight>
The mjpg-streamer is an open source media server. After it is started successfully you will see the following messages:
+
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">

</syntaxhighlight>
 
</syntaxhighlight>
  
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>
+
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>

[[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.

npi-config


5.3 连接有线网络

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

dhclient eth0

5.4 SSH登录

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:

ssh root@192.168.1.230

密码为fa。

5.5 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:

df -h

5.6 连接USB WiFi

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:

序号 型号
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]

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:

sudo ifconfig -a

用vi打开文件 /etc/wpa_supplicant/wpa_supplicant.conf:

sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

在文件末尾填入路由器信息如下所示:

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

其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。
保存退出后,执行以下命令即可连接WiFi:

$ sudo ifdown wlan0
$ sudo ifup wlan0

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:

$ sudo wpa_passphrase YourWiFiESSID

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。

5.7 连接USB摄像头模块(FA-CAM202)使用

USB camera
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) 启动系统,连接网络,以root用户登录终端并编译运行mjpg-streamer:

cd /root/mjpg-streamer
make
./start.sh

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:

 
 i: Using V4L2 device.: /dev/video0
 i: Desired Resolution: 1280 x 720
 i: Frames Per Second.: 30
 i: Format............: YUV
 i: JPEG Quality......: 90
 o: www-folder-path...: ./www/
 o: HTTP TCP port.....: 8080
 o: username:password.: disabled
 o: commands..........: enabled

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:
mjpg-streamer-cam500a

5.8 播放和录制音频

NEO2只提供了音频硬件接口(2.0mm 5pin 排针),引脚的定义如下:

Pin# Name Description
1 MICIN1P Microphone Positive Input
2 MICIN1N Microphone Negative Input
3 LINEOUTR LINE-OUT Right Channel Output
4 GND
5 LINEOUTL LINE-OUT Left Channel Output

用户需自行转接音频设备,参考下图:
耳麦标注
只有在已外接音频设备的前提下,才可以进行下列步骤测试播放和录制音频。
查看系统里的声卡设备:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audiocodec [audiocodec], device 0: SUNXI-CODEC sun50iw2codec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

播放音频:

$ aplay /root/Music/test.wav -D plughw:0

录制音频:

$ arecord -f cd -d 5 test.wav


6 如何编译Ubuntu-Core with Qt-Embedded系统

6.1 准备工作

访问此处下载地址的sources/nanopi-h5-bsp目录,下载所有压缩文件,使用7-Zip工具解压后得到lichee目录,如下:

ls ./
lichee

也可以从github上克隆lichee源码:

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

注:lichee是全志为其CPU的板级支持包所起的项目名称,里面包含了U-boot,Linux等源码和众多的编译脚本。

6.2 安装交叉编译器

访问此处下载地址的toolchain目录,下载压缩包gcc-linaro-arm-4.6.3.tar.xz和gcc-linaro-aarch64.tar.xz。
其中gcc-linaro-arm-4.6.3.tar.xz用于编译U-boot,gcc-linaro-aarch64.tar.xz用于编译Linux内核。下载完成后,将它们拷贝到源码lichee/brandy/toochain/目录下即可。 后面编译U-boot或者Linux内核时,编译脚本会自动解压并使用这两个编译器进行编译。

6.3 编译lichee源码

编译全志 H5 的BSP源码包必须使用64bit的Linux PC系统,并安装下列软件包,下列操作均基于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

编译lichee源码包,执行命令:

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

该命令会一次性编译好U-boot、Linux内核和模块。
lichee目录里内置了交叉编译器,当进行源码编译时,会自动使用该内置的编译器,所以无需手动安装编译器。

下列命令可以更新TF卡上的U-boot:

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

/dev/sdx请替换为实际的TF卡设备文件名。
内核boot.img和驱动模块均位于linux-3.10/output目录下,将boot.img拷贝到TF卡的boot分区的根目录即可更新内核。

6.4 编译U-boot

如果你想单独编译U-boot,可以执行命令:

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

6.5 编译Linux内核

如果你想单独编译Linux内核,可以执行命令:

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

编译完成后内核boot.img和驱动模块均位于linux-3.10/output目录下,将boot.img拷贝到TF卡的boot分区的根目录即可。

6.6 清理lichee源码

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

7 使用主线U-boot和Linux内核(64位)

NanoPi NEO2现已支持使用64位Linux内核,并使用64位Ubuntu Core 16.04,关于H5芯片系列开发板使用主线U-boot和Linux的方法,请参考维基:Mainline U-boot & Linux
