1 Introduction

Overview
Front
Back
  • The NanoPi NEO Core2 as its name tells is an alternative NanoPi NEO2 that works like a CPU board with male pin-headers. It has the same form facotor as the NanoPi NEO2, same pin descriptions and works with all the OS images the NanoPi NEO2 supports. The connectors and ports on the NEO2 are populated to pin-headers on the NEO2 Core. In addition the NEO Core2 can have an optional onboard eMMC flash and ESD protection for connectors and ports. There features are highly preferred by industrial customers.
  • The NEO2 Core uses a popular Allwinner H5 SoC and has onboard 1G DDR3 RAM. FriendlyElec offers models with three eMMC options: 8GB(default)/16GB/32GB. FriendlyElec migrated UbuntuCore with mainline kernel 4.11 for it. It works with other OS such as Armbian as well. Compared to the NanoPi NEO2 the NanoPi NEO Core2 runs more reliably with much less overheat. It is a good platform for IoT applications, mornitoring systems, smart control systems, cluster computing and AI applications.
  • FriendlyElec develops a Mini Shield for NanoPi NEO Core/Core2 which has the same form factor as the RPi 3. When a NanoPi NEO Core2 is connected to this Mini Shield the whole assembled module can be well fit into a common RPi 3's case.

Note: this method applies to making a bootable TF card with Debian too.

4.3.3 Flash OS to eMMC

  • Extract the image file 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 flashing is done insert this TF card to your NanoPi NEO Core2 and connect the board to a 5V/2A power NEO Core2 will be automatically powered on. If the green LED is solid on and the blue LED is flashing it indicates the system is being booted.
  • Run the following commands in a terminal to flash OS to eMMC:
$ su root
$ eflasher

The password for "root" is "fa". Type a number and press "enter" to select an OS you want to flash and then type "yes" and press "enter" to start flashing:
eflasher-console
After it is done power off the board and take out the TF card. Power on the board again and your board will boot from eMMC.

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.

PSU-ONECOM-NEO-Core2
Or you can use a USB to serial board to debug the system. Here is a hardware setup:
USB2UART-NEO-Core2

Mini Shield for NanoPi NEO Core/Core2 和 Core2

  • Ubuntu-Core's User Accounts:

Non-root User: 

   User Name: pi
   Password: pi

root: 

   User Name: root
   Password: fa

Core2-login
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 Extend NEO Core2'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

5.3 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, hardware interface(Serial/I2C/SPI/PWM/I2S) and etc. Type the following command to run this utility. 

$ sudo npi-config

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

5.4 Ethernet Connection

If a NanoPi NEO Core2 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

5.5 Connect USB WiFi to NEO Core2

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/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 MI WiFi mt7601

If you NanoPi NEO Core2 is connected to a USB WiFi and is powered up you can log into NEO Core2 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

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

  • Check device list
$ sudo nmcli dev

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

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

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

5.6 SSH登录

Core2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Core2。假设通过路由器查看到Core2的IP地址为192.168.1.230，你可以在PC机上执行如下命令登录Core2: 

$ ssh root@192.168.1.230

密码为fa。

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Core2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

Core2只提供了音频硬件接口(2.54mm 4pin 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 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: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

全志H5和H3这两款CPU内部都自带了同一个codec设备，在主线内核中被命名为[H3 Audio Codec]。

播放音频： 

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

录制音频： 

$ arecord -f cd -d 5 test.wav

5.9 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

6 如何编译Ubuntu-Core with Qt-Embedded系统

6.1 使用开源社区主线BSP

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

6.2 使用全志原厂BSP

6.2.1 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。

6.2.2 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。

6.2.3 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。

6.2.4 编译U-boot

注意: 必须先完整地编译整个lichee目录后，才能进行单独编译U-boot的操作。 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

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。

6.2.5 编译Linux内核

注意: 必须先完整地编译整个lichee目录后，才能进行单独编译Linux内核的操作。 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。

6.2.6 清理lichee源码

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