4 Get Started

4.1 Essentials You Need

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

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

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

4.3 Make an Installation TF Card

4.3.1 Get Image Files

Visit this link download link to download image files and the flashing utility:

Image Files
nanopi-neo-ubuntu-core-qte-sd4g.img.zip	UbuntuCore with Qt-Embedded Image File
Flash Utility:
win32diskimager.rar	Windows utility for flashing Debian image. Under Linux users can use "dd"

4.3.2 Make UbuntuCore with Qt Embedded Image Card

• Extract the nanopi-neo-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 flashing is done insert this TF card to your NanoPi NEO and connect the board to a 5V/2A power NEO will be automatically powered on. If the blue LED is flashing it indicates the system is being booted.

5 Work with Ubuntu-Core with Qt-Embedded

5.1 Run Ubuntu-Core with Qt-Embedded

• Insert a TF card with UbuntuCore image files into your NanoPi NEO, connect the board to a 5V/2A power source the board will be automatically powered on. If you can see the blue LED flashing it means your board is working and UbuntuCore is being loaded.
  
• 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 to a PC via the PSU-ONECOM and you can power on your NEO from either the PSU-ONECOM or the board's MicroUSB:

• 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:

5.3 Ethernet Connection

If the NanoPi NEO 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.

5.4 Login via SSH

The NanoPi NEO 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:

$ ssh root@192.168.1.230

The password is fa

5.5 Extend NEO'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

5.6 Connect USB WiFi to NEO

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 is connected to a USB WiFi and is powered up you can log into NEO 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: NetworkManager

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

The FA-CAM202 is a 2M-pixel USB camera module. Boot your NEO, connect NEO to the internet, log in the system as root, compile and run the mjpg-streamer utility:

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

The mjpg-streamer is an open source media server. After it is started successfully you will see the following messages:

 
 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

In our case our NEO'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:

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:

$ su root
$ 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

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.

5.8 Check CPU's Working Temperature

Open a terminal on your NanoPi NEO and you can type the following command to read H3's temperature and frequency:

$ cpu_freq

5.9 Check System Information with Rpi-Monitor

Our Ubuntu-Core contains the Rpi-Monitor utility with which users can check system information and status.
In our case our NEO's IP was 192.168.1.230 and we typed the following IP in a browser:

192.168.1.230:8888

We entered the following page:

Users can easily check these system information and status.

Please refer to WiringPi for NanoPi

7 Make Your Own Ubuntu-Core with Qt-Embedded

7.1 Preparations

Visit this link download link and enter the "sources/nanopi-H3-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 ./
android lichee

Or you can get it from our github:

$ git clone https://github.com/friendlyarm/h3_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.

7.2 Install Cross Compiler

• Visit this site download link, enter the "toolchain" directory, download the cross compiler "gcc-linaro-arm.tar.xz" and copy it to the "lichee/brandy/toochain/" directory.
  

If you want to compile your own programs you need to setup a development environment. For more details about this you can refer to section 8 "Setup Cross Compiler for User Space Programs".
(Allwinner's compiler doesn't work very well for some programs)

7.3 Compile lichee Source Code

Compilation of the H3'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 u-boot-tools

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

$ cd lichee
$ ./build.sh -p sun8iw7p1 -b nanopi-h3

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

7.4 Package System Modules

$ ./gen_script.sh -b nanopi-neo

The gen_script.sh script patches the U-boot with Allwinner features and copies the generated executables including u-boot and Linux kernel and configuration files to the "lichee/tools/pack/out/" directory and generates a script.bin file.

Type the following command to update the U-boot on the MicroSD card:

$ ./fuse_uboot.sh /dev/sdx

Note: you need to replace "/dev/sdx" with the device name in your system.
The boot.img and kernel modules are under the "linux-3.4/output" directory. You can copy the new boot.img file to your MicroSD card's boot section.

7.5 Compile U-boot

$ ./build.sh -p sun8iw7p1 -b nanopi-h3 -m uboot
$ ./gen_script.sh -b nanopi-neo

The gen_script.sh script patches the U-boot with Allwinner features. A U-boot without these features cannot work.
Type the following command to update the U-boot on the MicroSD card:

$ ./fuse_uboot.sh /dev/sdx

Note: you need to replace "/dev/sdx" with the device name in your system.

7.6 Compile Linux Kernel

If you want to compile the Linux kernel run the following command:

$ ./build.sh -p sun8iw7p1 -b nanopi-h3 -m kernel

After the compilation is done a boot.img and its kernel modules will be generated under "linux-3.4/output".

7.7 Clean Source Code

$ ./build.sh -p sun8iw7p1_linux -b nanopi-h3 -m clean

8 Setup Cross Compiler for User Space Programs

Download and extract cross compiler:

$ git clone https://github.com/friendlyarm/prebuilts.git
$ sudo mkdir -p /opt/FriendlyARM/toolchain
$ sudo tar xf prebuilts/gcc-x64/arm-cortexa9-linux-gnueabihf-4.9.3.tar.xz -C /opt/FriendlyARM/toolchain/

Add the compiler's path to the "PATH" variable by appending the following lines in the ~/.bashrc file:

export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH
export GCC_COLORS=auto

Run the ~/.bashrc script to make the changes in effect immediately in your working shell. Attention: there is a space after ".":

$ . ~/.bashrc

This is a 64-bit compiler and it cannot run on a 32-bit Linux. You can check whether or not your compiler is setup correctly by running the following commands:

$ arm-linux-gcc -v
Using built-in specs.
COLLECT_GCC=arm-linux-gcc
COLLECT_LTO_WRAPPER=/opt/FriendlyARM/toolchain/4.9.3/libexec/gcc/arm-cortexa9-linux-gnueabihf/4.9.3/lto-wrapper
Target: arm-cortexa9-linux-gnueabihf
Configured with: /work/toolchain/build/src/gcc-4.9.3/configure --build=x86_64-build_pc-linux-gnu
--host=x86_64-build_pc-linux-gnu --target=arm-cortexa9-linux-gnueabihf --prefix=/opt/FriendlyARM/toolchain/4.9.3
--with-sysroot=/opt/FriendlyARM/toolchain/4.9.3/arm-cortexa9-linux-gnueabihf/sys-root --enable-languages=c,c++
