Introduction

Overview
Front
Back
  • The NanoPi NEO Core(abbreviated as "NEO Core") is an alternative NanoPi NEO that works like a CPU board with male pin-headers. It has the same form factor as the NanoPi NEO and same pin descriptions. The connectors and ports are populated to pin-headers on the NEO Core. The NanoPi NEO Core has ESD protection for its MicroUSB port and TF card slot. In addition the NEO Core can have an optional onboard eMMC flash which is preferred by industrial customers.
  • The NEO Core uses a popular Allwinner H3 SoC and has onboard 256M/512M DDR3 RAM. FriendlyElec offers models with three eMMC options: 8GB/16GB/32GB and one that doesn't have eMMC at all.
  • FriendlyElec migrated UbuntuCore with mainline kernel 4.11 for it.
  • FriendlyElec develops a Mini Shield for NanoPi NEO Core/Core2 which has the same form factor as the RPi 3. When a NanoPi NEO Core is connected to this Mini Shield the whole assembled module can be well fit into a common RPi 3's case.

  • microSD Card/TF Card: Class 10 or Above, minimum 8GB SDHC
  • microUSB power. A 5V/2A power is a must
  • A Host computer running Ubuntu 16.04 64 bit system

TF Cards We Tested

To make your NanoPi NEO Core 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

Make Bootable TF Card

Make UbuntuCore with Qt Embedded Image Card
  • 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 Core and connect the board to a 5V/2A power NEO Core 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.

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

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 Core and connect the board to a 5V/2A power NEO Core 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.


Mini Shield for NanoPi NEO Core/Core2

Here is a setup where we connect a NanoPi NEO Core to a Mini Shield for NanoPi NEO Core/Core2. Here is an introduction to Mini Shield for NanoPi NEO Core/Core2 Mini Shield
: Mini Shield for NanoPi NEO Core/Core2

FriendlyCore的使用

介绍

FriendlyCore,是一个没有X-windows环境,基于Ubuntu core构建的系统,使用Qt-Embedded作为图形界面的轻量级系统,兼容Ubuntu系统软件源,非常适合于企业用户用作产品的基础OS。

本系统除了保留Ubuntu Core的特性以外,还包括以下特性:

  • 支持电容和电阻触摸屏 (型号:S700, X710, S70, HD702, S430, HD101, S70等友善推出的LCD屏)
  • 支持WiFi连接
  • 支持以太网连接
  • 支持蓝牙,已预装bluez等相关软件包
  • 支持音频播放
  • 支持Qt5.9 EGLES和OpenGL ES1.1/2.0 (限S5P4418/S5P6818平台)

运行FriendlyCore

  • 要在电视上进行操作,你需要连接USB鼠标和键盘。
  • 如果您需要进行内核开发,你最好选购一个串口配件,连接了串口,则可以通过串口终端对开发板进行操作。

以下是串口配件的接法,接上串口,即可调试。
接上串口后,你可以选择从串口模块的DC口或者从MicroUSB口 (如果有) 进行供电:
PSU-ONECOM-NEO-Core.jpg
也可以使用USB转串口模块调试,请注意需要使用5V/2A电源给开发板MicroUSB供电:
USB2UART-NEO-Core.jpg

  • FriendlyCore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:
$ sudo apt-get update

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:

$ sudo npi-config

npi-config的显示界面如下所示:
npi-config

扩展TF卡文件系统

第一次启动FriendlyCore系统时,系统会自动扩展文件系统分区,请耐心等待,TF卡/eMMC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

连接WiFi

FriendlyCore 使用 NetworkManager 工具来管理网络,其在命令行下对应的命令是 nmcli,要连接WiFi,相关的命令如下:

  • 查看网络设备列表
$ sudo nmcli dev

注意,如果列出的设备状态是 unmanaged 的,说明网络设备不受NetworkManager管理,你需要清空 /etc/network/interfaces下的网络设置,然后重启.

  • 开启WiFi
$ sudo nmcli r wifi on
  • 扫描附近的 WiFi 热点
$ sudo nmcli dev wifi
  • 连接到指定的 WiFi 热点
$ sudo nmcli dev wifi connect "SSID" password "PASSWORD"

请将 SSID和 PASSWORD 替换成实际的 WiFi名称和密码。
连接成功后,下次开机,WiFi 也会自动连接。

更详细的NetworkManager使用指南可参考这篇文章: Use NetworkManager to configure network settings

  • 使用USB WiFi

系统已经支持市面上众多常见的USB WiFi,已测试过的USB WiFi型号如下:

序号 型号
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 小米WiFi mt7601

连接以太网

默认插上网线开机,会自动连接并通过DHCP获取IP地址,如需要配置静态IP地址,请参考 NetworkManager 的相关文档: Use NetworkManager to configure network settings

使用蓝牙

如果你的开发板板载有蓝牙模块,可输入以下命令搜索周边的蓝牙设备:

hcitool scan

使用hciconfig命令来了解接口的状态。


播放音频

在串口终端执行以下aplay命令播放一段音频:

aplay -t raw -c 2 -f S16_LE -r 44100 /root/test.pcm

HDMI输出声音

系统默认从3.5mm耳机座输出声音,想从HDMI输出需要修改文件系统上的配置文件/etc/asound.conf如下:

pcm.!default {
    type hw
    card 1
    device 0
}
 
ctl.!default {
    type hw
    card 1
}

card 0代表3.5mm耳机孔,card 1代表HDMI音频。设置完成后需要重启系统才能生效。

连接USB摄像头模块(FA-CAM202)

FA-CAM202是一款200万像素的USB摄像头模块。
连接测试USB摄像头的方法请参考:连接DVP摄像头模块(CAM500B)

开发自已的Qt应用

请参考 How to build Qt application

开机自动运行Qt示例程序

使用npi-config工具进行开启:

sudo npi-config

进入Boot Options -> Autologin -> Qt/Embedded,选择Enable然后重启即可。

运行Qt示例程序

执行以下命令:

$ sudo /opt/QtE-Demo/run.sh

运行结果如下,这是一个开源的QtDemo:
K2-QtE

连接DVP摄像头模块(CAM500B)

注:该功能仅支持使用Linux-3.4.y的系统固件。
CAM500B是一款500万像素摄像头模块,以DVP并行信号输出,详细信息请参考Matirx-CAM500B
连接开发板和CAM500B,然后上电启动系统,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

假设开发板的IP地址为192.168.1.230,在PC的浏览器中输入 192.168.1.230:8080 就能浏览摄像头采集的画面了,效果如下:
mjpg-streamer-cam500a
mjpg-streamer是用libjpeg对摄像头数据进行软编码,你可以使用ffmpeg对摄像头数据进行硬编码,这样能大大降低CPU的占用率并提高编码速度:

$ 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

默认会录制30秒的视频,输入q能终止录制。录制完成后会在当前目录生成一个名为test.mp4的视频文件,可将其拷贝到PC上进行播放验证。

命令行查看CPU工作温度

在串口终端执行如下命令,可以快速地获取CPU的当前温度和运行频率等信息:

$ cpu_freq

通过Rpi-Monitor查看系统状态

系统里已经集成了Rpi-Monitor,该服务允许用户在通过浏览器查看开发板系统状态。
假设开发板的IP地址为192.168.1.230,在PC的浏览器中输入下述地址:

192.168.1.230:8888

可以进入如下页面:
rpi-monitor
用户可以非常方便地查看到系统负载、CPU的频率和温度、可用内存、SD卡容量等信息。

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。
我们在FriendlyCore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
