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 recommand 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

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-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-core-qte-sd4g.img.zip and win32diskimager.rar files. Insert a TF card(at least 4G) 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:

PSU-ONECOM-NEO

  • It has two user names: root and fa and the password for both is "fa".
  • Update packages
sudo apt-get update

5.2 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.In this case you can try obtaining an IP by using the following command 

dhclient eth0

5.3 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。

5.4 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's experience

  • Solution 1: Extend your card's rootfs section under a host PC:
sudo umount /dev/sdx?
sudo parted /dev/sdx unit % resizepart 2 100 unit MB print
sudo resize2fs -f /dev/sdx2

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

  • Solution 2: Extend your card's rootfs section under NEO running UbuntuCore:
sudo fs_resize

Following the prompt type in "y" to start re-sizing the file system and a second "y" to reboot the NEO. After the NEO is rebooted check the new section by using the following command: 

df -h

5.5 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: 

ifconfig -a

Open the /etc/wpa_supplicant/wpa_supplicant.conf file 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 to connect to your WiFi router: 

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 and you will get a new password in the /etc/wpa_supplicant/wpa_supplicant.conf file. Now you can replace the existing password in the wlan0 file with the new one.

5.6 Check CPU's Working Temperature

You can use the following command to read H3's temperature and frequency 

cpu_freq

6 Make Your Own Ubuntu-Core with Qt-Embedded

Visit download link and go to the sources directory and download nanopi-H3-bsp.
Use the 7-zip utility to uncompress it and a lihee directory and an Android directory will be generated. 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.

6.1 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 un 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.

6.2 Package System Modules

./gen_script.sh nanopi-neo

This command 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.
The script.bin file is designed by Allwinner for its CPUs. For more details refer to script.bin.

6.3 Compile U-boot

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

After a u-boot executable is generated some extra patches need to be patched to it. Run "./build.sh pack" to patch this executable.
If you want to manually patch the executable refer to H3_Manual_build_howto and run the following commands to update the u-boot in the TF card: 

./fuse_uboot.sh /dev/sdx

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

6.4 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 uImage and its kernel modules will be generated under "linux-3.4/output".

6.5 Clean Source Code

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