|}

====Boot OS from MicroSD Card====
=====Make Installation MicroSD Card=====
* Extract the nanopi-air-core-qte-sd4g.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 TF card's drive, the wanted image file and click on "write" to start flashing the SD card till it is done.
* Insert this card into your AIR's MicroSD card slot and power on (with a 5V/2A power source). If the green LED is on and blue LED is blinking this indicates your AIR has successfully booted.<br />
Note:you can make a Debian/Ubuntu image card in this way too.

====Flash image to eMMC====
* Extract the nanopi-air-eflasher-sd8g.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 AIR and power on (with a 5V/2A power source) the board. If the green LED is on and blue LED is blinking it indicates your eflasher has started installation.<br />
* Run the following command on a terminal:
<syntaxhighlight lang="bash">
eflasher
</syntaxhighlight>
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.

<!---
==eflasher Functions==
===System Login via Serial Port===
* 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 AIR to a PC via a serial cable you will see system messages output to the PC’s serial terminal:
[[File:PSU-ONECOM-AIR.jpg|frameless|400px|PSU-ONECOM-AIR]]
* The password for both "root" and "fa" is "fa"
* Update software packages
<syntaxhighlight lang="bash">
apt-get update
</syntaxhighlight>

===Extend TF Card's Section===
We strongly recommend you to do this right after you have made an installation TF card since this will greatly enhance your NEO Air's experience<br>
* Solution 1: Extend your card's rootfs section under a host PC:
<syntaxhighlight lang="bash">
sudo umount /dev/sdx?
sudo parted /dev/sdx unit % resizepart 2 100 unit MB print
sudo resize2fs -f /dev/sdx2
</syntaxhighlight>
Note: you need to replace "/dev/sdx" with the device name in your system.<br>

* Solution 2: Extend your card's rootfs section under NEO Air running UbuntuCore:
<syntaxhighlight lang="bash">
sudo fs_resize
</syntaxhighlight>
Following the prompt type in "y" to start re-sizing the file system and a second "y" to reboot the NEO Air. After the NEO Air is rebooted check the new section by using the following command:
<syntaxhighlight lang="bash">
df -h
</syntaxhighlight>

===WiFi Connection===
* An IPX Antenna is A MUST.
[[File:NanoPi NEO Air-IPX.png|frameless|400px|NanoPi NEO Air-IPX]]<br/>
Insert a TF card with eflasher to a PC running Ubuntu and make the following changes in the etc/wpa_supplicant/wpa_supplicant.conf file under the rootfs section:
<syntaxhighlight lang="bash">
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
        ssid="YOUR-WIFI-ESSID"
        psk="YOUR-WIFI-PASSWORD"
}
</syntaxhighlight>
Note: the "YOUR-WIFI-ESSID" and "YOUR-WIFI-PASSWORD" need to be replaced with your actual ESSID and password.<br>
Save, exit and insert the TF card to your AIR. After power on your AIR and the blue LED is blinking for one minute you will be able to check AIR's IP address.

===SSH Login===
The NanoPi NEO AIR has no display interface. If you don't have a serial communication board to connect your AIR to a PC you can log in your AIR via SSH. In our example the AIR's IP address was 192.168.1.230 and we logged in AIR by using the following command:
<syntaxhighlight lang="bash">
ssh root@192.168.1.230
</syntaxhighlight>
The password is fa。

===Flash Image to eMMC===
The eflasher utility has a Ubuntu-Core system. After you run eflasher you can flash Ubuntu-core to eMMC by using the following command:
<syntaxhighlight lang="bash">
flash_eMMC.sh -d /mnt/sdcard/Ubuntu-Core-qte/
</syntaxhighlight>
This command flashes the Ubuntu-Core image to eMMC, copies the wifi configuration file to eMMC and extends eMMC's file system.
After it is done you will see the following message:
<syntaxhighlight lang="bash">
INFO: flash system to eMMC success
</syntaxhighlight>
Power off the board,
--->

==Work with Ubuntu-Core==
===Run Ubuntu-Core===
* Insert a MicroSD card with Ubuntu-Core image into your NanoPi NEO Air, connect the NanoPi NEO Air to a 5V/2A power source the NanoPi NEO Air will be automatically powered on. If you can see the blue LED flashing it means your board is working.<br />
* 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.<br />
* Here is a setup where we connect a NanoPi NEO Air to a PC via the PSU-ONECOM and you can power on your Air from either the PSU-ONECOM or its MicroUSB:
[[File:PSU-ONECOM-AIR.jpg|frameless|400px|PSU-ONECOM-AIR]]
* The password for "root" is "fa".
* Update packages
<syntaxhighlight lang="bash">
sudo apt-get update
</syntaxhighlight>

===Extend TF Card's rootfs Section===
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:
<syntaxhighlight lang="bash">
df -h
</syntaxhighlight>

===Wireless Connection===
Note: An IPX antenna is A MUST.<br/>
[[File:NanoPi NEO Air-IPX.png|frameless|400px|NanoPi NEO Air-IPX]]

Open the file "/etc/wpa_supplicant/wpa_supplicant.conf" with vi or gedit and append the following lines:
<syntaxhighlight lang="bash">
network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}
</syntaxhighlight>
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.<br/>
Save, exit and run the following commands your board will be connected to your specified WiFi:<br />
<syntaxhighlight lang="bash">
ifdown wlan0
ifup wlan0
</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:<br/>
<syntaxhighlight lang="bash">
wpa_passphrase YourWiFiESSID
</syntaxhighlight>
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.
<!---
If the system's WiFi AP mode is on it cannot search and connect to a wireless router. You need to turn off the WiFi AP mode by following the instructions below: 
<syntaxhighlight lang="bash">
su
turn-wifi-into-apmode no
</syntaxhighlight>
--->

===Login via SSH===
The NanoPi NEO Air 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 Air:
<syntaxhighlight lang="bash">
ssh root@192.168.1.230
</syntaxhighlight>
The password is fa 

===Check CPU's Working Temperature===
Type the following command on a terminal to read H3's temperature and frequency:
<syntaxhighlight lang="bash">
cpu_freq
</syntaxhighlight>

===Check System Information with Rpi-Monitor===
Our Ubuntu-Core contains the Rpi-Monitor utility with which users can check system information and status.<br>
In our case our NEO Air's IP was 192.168.1.230 and we typed the following IP in a browser:
<syntaxhighlight lang="bash">
192.168.1.230:8888
</syntaxhighlight>
We entered the following page:<br>
[[File:rpi-monitor.png|frameless|500px|rpi-monitor]] <br>
Users can easily check these system information and status.

===Connect NanoPi NEO AIR to DVP Camera(CAM500B)===
The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to [[Matrix - CAM500B]].<br>
[[File:NanoPi-AIR-cam500b.jpg|frameless|500px|NanoPi-AIR-cam500b]] <br>
Boot your NanoPi NEO AIR, connect your NEO AIR to a network, log into the board as root and run "mjpg-streamer":
<syntaxhighlight lang="bash">
cd /root/mjpg-streamer
make
./start.sh
</syntaxhighlight>
The mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:
<syntaxhighlight lang="bash"> 
 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
</syntaxhighlight>

In our case the NEO AIR's IP address was 192.168.1.230. We typed 192.168.1.230:8080 in a browser and were able to view the images taken from the camera's. Here is what you would expect to observe:<br>
[[File:mjpg-streamer-cam500a.png|frameless|600px|mjpg-streamer-cam500a]] <br>
The mjpg-streamer soft-encodes data with libjpeg and you can hard-encode its data with ffmpeg which will greatly increase CPU's efficiency and speed up data encoding:
<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. Typing "q" stops video recording. After recording is stopped a test.mp4 file will be generated.

===Bluetooth===
Install Bluetooth packages:
<syntaxhighlight lang="bash">
apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push time bc
</syntaxhighlight>
In our test case we used a Samsung Galaxy A7 Android phone. Connect a wireless antenna to your Air and type the following command to search a surrounding Bluetooth device:
<syntaxhighlight lang="bash">
hcitool scan
</syntaxhighlight>
Our Samsung Samsung Galaxy A7 was detected and its MAC address was "50:C8:E5:A7:31:D2". We had a "test.jpg" file on our NEO Air and we sent it to A7 by running the following command:
<syntaxhighlight lang="bash">
bt_send_file.sh -a 50:C8:E5:A7:31:D2 -f test.jpg
</syntaxhighlight>
On the phone a popup window would show up. After we clicked to accept this file transfer would start. After this transfer was done we got the following messages:
<syntaxhighlight lang="bash">
name=test.jpg, size=2215936
Local device A1:A3:C1:79:66:6E
Remote device 50:C8:E5:A7:31:D2 (12)
Connection established
send 2164K finish, speed=5.6 K/s
</syntaxhighlight>
We found this file on the phone and the file transfer was successful.

==Make Your Own Ubuntu-Core with Qt-Embedded==
===Preparations===
Visit this link [https://www.mediafire.com/folder/sr5d0qpz774cs/NanoPi-NEO_Air 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 lihee directory and an Android directory will be generated.You can check that by running the following command:
<syntaxhighlight lang="bash">
ls ./
android lichee
</syntaxhighlight>

Or you can get it from our github:
<syntaxhighlight lang="bash">
git clone https://github.com/friendlyarm/h3_lichee.git lichee
</syntaxhighlight>
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.

===Install Cross Compiler===
Visit this site [https://www.mediafire.com/folder/sr5d0qpz774cs/NanoPi-NEO_Air download link], enter the "toolchain" directory, download the cross compiler "gcc-linaro-arm.tar.xz" and copy it to the "lichee/brandy/toochain/" directory.

===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:
<syntaxhighlight lang="bash">
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
</syntaxhighlight>

Enter the lichee directory and un the following command to compile the whole package:
<syntaxhighlight lang="bash">
cd lichee
./build.sh -p sun8iw7p1 -b nanopi-h3
</syntaxhighlight>
After this compilation succeeds a u-boot, Linux kernel and kernel modules will be generated.<br>
Note: the lichee directory contains a cross-compiler we have setup. When the build.sh script runs it will automatically call this cross-compiler.

===Package System Modules===
<syntaxhighlight lang="bash">
./gen_script.sh -b nanopi-neo
</syntaxhighlight>
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.<br>

Type the following command to update the U-boot on the MicroSD card:
<syntaxhighlight lang="bash">
./fuse_uboot.sh /dev/sdx
</syntaxhighlight>
Note: you need to replace "/dev/sdx" with the device name in your system.<br>
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.

===Compile U-boot===
You can compile u-boot individually by using the following command:
<syntaxhighlight lang="bash">
./build.sh -p sun8iw7p1 -b nanopi-h3 -m uboot
./gen_script.sh -b nanopi-neo
</syntaxhighlight>
The gen_script.sh script patches the U-boot with Allwinner features. A U-boot without these features cannot work.<br>
Type the following command to update the U-boot on the MicroSD card:
<syntaxhighlight lang="bash">
./fuse_uboot.sh /dev/sdx
</syntaxhighlight>
Note: you need to replace "/dev/sdx" with the device name in your system.

===Compile Linux Kernel===
If you want to compile the Linux kernel run the following command:
<syntaxhighlight lang="bash">
./build.sh -p sun8iw7p1 -b nanopi-h3 -m kernel
</syntaxhighlight>
After the compilation is done a uImage and its kernel modules will be generated under "linux-3.4/output".

===Clean Source Code===
<syntaxhighlight lang="bash">
./build.sh -p sun8iw7p1_linux -b nanopi-h3 -m clean
</syntaxhighlight>
