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。

If the NanoPi NEO Plus2 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.

5 Get Started

5.1 Essentials You Need

Before starting to use your NanoPi NEO Plus2 get the following items ready:

  • NanoPi NEO Plus2
  • 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

5.2 TF Cards We Tested

To make your NanoPi NEO Plus2 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

5.3 Make an Installation TF Card

5.3.1 Get Image Files

Visit this link download link to download image files(under the "official-ROMs" directory) and the flashing utility(under the "tools" directory):

Image Files:
nanopi-neo-plus2_ubuntu-core-xenial_4.x.y_YYYYMMDD.img.zip Ubuntu-Core with Qt-Embedded image file, kernel:Linux-4.x
nanopi-neo-plus2_debian-nas-jessie_4.x.y_YYYYMMDD.img.zip NAS image file, kernel:Linux-4.x, for 1-bay NAS Dock
nanopi-neo-plus2_ubuntu-oled_4.x.y_YYYYMMDD.img.zip OLED image file, kernel:Linux-4.x, for NanoHat OLED
nanopi-neo-plus2_eflasher_4.x.y_YYYYMMDD.img.zip eflasher image file, kernel:Linux-4.x
Flash Utility:
win32diskimager.rar Windows utility for flashing Debian image. Under Linux users can use "dd"

5.3.2 Make Installation MicroSD Card

  • Extract the nanopi-neo-plus2_ubuntu-core-xenial_4.x.y_YYYYMMDD.img.zip and win32diskimager.rar. Insert a MicroSD card(at least 8G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your card's drive, the wanted image file and click on "write" to start flashing the card till it is done.
  • Insert this card into your NEO Plus2's MicroSD card slot and power on (with a 5V/2A power source). If the blue LED blinks this indicates your NEO Plus2 has successfully booted.

5.3.3 Flash Image to eMMC

  • Extract the nanopi-neo-plus2_eflasher_4.x.y_YYYYMMDD.img.zip package and win32diskimager.rar. Insert a MicroSD card(at least 8G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your SD card's drive, the wanted image file and click on "write" to start flashing the MicroSD card.
  • Insert this card into your NEO Plus2 and power on (with a 5V/2A power source) the board. If the green LED is on and blue LED is blinks it indicates your eflasher has started successfully.
  • Run the following command on a terminal:
$ eflasher

Select your wanted OS and type "yes" to start flashing. After it is done take off the card, reboot your board it will boot from eMMC.

6 Work with Ubuntu-Core with Qt-Embedded

6.1 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 NEO Plus2 to a PC via the PSU-ONECOM and you can power on your NEO Plus2 from either the PSU-ONECOM or its MicroUSB:

PSU-ONECOM-NEO_Plus2
You can use a USB to Serial conversion board too. Make sure you use a 5V/2A power to power your NEO Plus2 from its MicroUSB port:
USB2UART-NEO-Plus2

  • Default Login Account:

Regular User: 

   User Account: pi
   Password: pi

Root: 

   User Account: root
   Password: fa

By default pi logs in automatically. You can disable its auto-login by using "sudo npi-config".

  • Update Software Packages:
sudo apt-get update

6.2 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

6.3 Ethernet Connection

If the NanoPi NEO Plus2 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. Obtain an IP address 

dhclient eth0

6.4 Login via SSH

The NanoPi NEO Plus2 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 NEO Plus2: 

$ ssh root@192.168.1.230

The password is fa

6.5 Extend NEO Plus2's TF Card Section

When Ubuntu 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

6.6 Wireless Connection

Note: An IPX antenna is A MUST.
After your NanoPi NEO Plus2 is powered up you can log into NEO Plus2 and run the following command to check if a WiFi device is recognized. If "wlan0" is listed it indicates your WiFi has been recognized: 

sudo ifconfig -a

Open the file "/etc/wpa_supplicant/wpa_supplicant.conf" with vi or gedit 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 your board will be connected to your specified WiFi:

ifdown wlan0
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:

wpa_passphrase YourWiFiESSID

Following the prompt type in your password. If you open the file "/etc/wpa_supplicant/wpa_supplicant.conf" you will find that your password has been updated and you can delete your clear-text password.

6.7 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NEO Plus2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

6.8 播放和录制音频

NEO Plus2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 地
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

6.9 通过WiringNP测试GPIO

wiringPi库最早是由Gordon Henderson所编写并维护的一个用C语言写成的类库，除了GPIO库，还包括了I2C库、SPI库、UART库和软件PWM库等，由于wiringPi的API函数和arduino非常相似，这也使得它广受欢迎。 wiringPi库除了提供wiringPi类库及其头文件外，还提供了一个命令行工具gpio：可以用来设置和读写GPIO管脚，以方便在Shell脚本中控制GPIO管脚。
Ubuntu-Core系统中集成了这个工具以便客户测试GPIO管脚。详细信息请参看 WiringNP

7 如何编译Ubuntu-Core with Qt-Embedded系统

7.1 使用开源社区主线BSP

NEO Plus2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-4.x.y的方法，请参考维基：Mainline U-boot & Linux
