5.2.1.2 Tools (optional)

Visit download link to download tools (in the "05_Tools" directory).

5.2.2 Comparison of Linux-3.4 and Linux-4.14

• Our Linux-3.4 is provided by Allwinner. Allwinner has done a lot of customization work which on one hand contains many features and functions but on the other hand incurs overheat issues. If your application needs to use VPU or GPU you need to use the 3.4 kernel based ROM and use a heat sink together with your board.
• Our Linux-4.14 is based on the mainline kernel. We will keep this kernel with the latest one released by Linus Torvalds. This kernel is stable and doesn't generate heat that much. If your application doesn't need to use VPU or GPU we recommend you to use this kernel.
• For more details about the Linux-4.14 kernel refer to: Building U-boot and Linux for H5/H3/H2+

5.2.3 Android

5.2.3.1 Flash to TF

Note:before make a MicroSD card to an Android image card you need to format this card.

• On a Windows PC run the HDDLLF.4.40 utility as administrator. Insert a TF card(at least 8G) into this PC and format it. After formatting is done take out the TF card, insert it into the PC again and format it with Windows internal format utility to format it to FAT32. After this formatting is done take out the card.
• Extract the the Android image and PhoenixCard_V310.rar . Insert the TF card you made in the previous step into a Windows PC and run the PhoenixCard_V310 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.

(In the screenshot an Android image file for the NanoPi M1 Plus was selected. You need to select a correct image file for your board.)

• Insert this card into your board' BOOT slot and power on (with a 5V/2A power source). If the green LED is on and the blue LED is blinking this indicates your board has successfully booted.
  

6 Working with Debian

6.1 Ethernet Connection

• If the board is connected to a network via Ethernet before it is powered on, it will automatically obtain an IP after it is powered up.

6.2 Wireless Connection

Under Debian you can manage your network with NetworkManager.
After Debian boots click on the network icon on the bottom right of the task bar a NetworkManger menu will pop up and all the available networks will be listed. If there is an active wireless network you will see something similar to the following screenshot:

You can click on a WiFI AP and connect your board to it.
For more details refer to:NetworkManager.

For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:

Index	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
6	5G USB WiFi RTL8821CU
7	5G USB WiFi RTL8812AU

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

• Change to root

$ su root

• Check device list

$ nmcli dev

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

• Start WiFi

$ nmcli r wifi on

• Scan Surrounding WiFi Sources

$ nmcli dev wifi

• Connect to a WiFi Source

$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

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

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:

$ apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.

6.3 Install Debian Packages

We provide a Debian Jessie image. You can install Jessie's packages by commanding "apt-get". If this is your first installation you need to update the package list by running the following command

apt-get update

You can install your preferred packages. For example if you want to install an FTP server you can do this:

apt-get install vsftpd

Note: you can change your download server by editting "/etc/apt/sources.list". You can get a complete server list from [1]. You need to select the one with "armhf".

6.4 Set Audio Device

If your system has multiple audio devices such as HDMI-Audio, 3.5mm audio jack and I2S-Codec you can set system's default audio device by running the following commands.

• After your board is booted run the following commands to install alsa packages:

$ apt-get update
$ apt-get install libasound2
$ apt-get install alsa-base
$ apt-get install alsa-utils

• After installation is done you can list all the audio devices by running the following command. Here is a similar list you may see after you run the command:

$ aplay -l
card 0: HDMI
card 1: 3.5mm codec
card 2: I2S codec

"card 0" is HDMI-Audio, "card 1" is 3.5mm audio jack and "card 2" is I2S-Codec. You can set default audio device to HDMI-Audio by changing the "/etc/asound.conf" file as follows:

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

If you change "card 0" to "card 1" the 3.5mm audio jack will be set to the default device.
Copy a .wav file to your board and test it by running the following command:

$ aplay /root/Music/test.wav

You will hear sounds from system's default audio device.
If you are using H3/H5/H2+ series board with mainline kernel, the easier way is using npi-config。

6.5 Login via VNC and SSH

If your board is not connected to a display device you can login to your board from a mobile phone. You need to download and install a "VNC Viewer" from here on a mobile phone and login to the board via VNC at port 1. Its default password is "fa123456".
Here is a screenshot which shows how it looks like when users login to the board from an iPhone via VNC:

In our case our board's IP address is 192.168.1.230. You can login via SSH by running the following commands:

$ ssh root@192.168.1.230

The password is fa.

6.6 Connect to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera.
Refer to this link for more details on how to connect to a FA-CAM202: Connect NanoPi M1 to DVP Camera CAM500B
In Debian, click on "other"-->"xawtv" on the left bottom of the GUI and the USB Camera application will be started. After enter "welcome to xawtv！" click on "OK" to start exploring.

6.7 Use OpenCV to Access Camera

• The full name of "OpenCV" is Open Source Computer Vision Library and it is a cross platform vision library.
• Make sure your board is connected to the internet and an HDMI monitor, Boot Debian and login.
• Install OpenCV libraries:

$ apt-get update
$ apt-get install libcv-dev libopencv-dev

• Refer to the instructions in the previous sections to make sure the camera works
• Compile and run a code sample（Official Code Sample in C++ provided by the OpenCV organization):

$ cd /home/fa/Documents/opencv-demo
$ make
$ ./demo

6.8 Connect 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.
connect your H3 board to a CAM500B. Then boot OS, connect your board to a network, log into the board as root and run "mjpg-streamer":

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

The mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:

 
 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 the board'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:

The mjpg-streamer utility uses libjpeg to software-encode steam data. The Linux-4.x based ROM currently doesn't support hardware-encoding. If you use a Linux-3.x based ROM you can use the ffmpeg utility to hardware-encode stream data and this can greatly release CPU's resources and speed up encoding:

$ 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. Typing "q" stops video recording. After recording is stopped a test.mp4 file will be generated.

6.9 Check CPU's Working Temperature

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

cpu_freq

6.10 Test GPU

Note: this function is only supported in Allwinner Linux-3.4.y.
After OS loads please login from a terminal and run the following command:

glmark2-es2

6.11 Test VPU

Note: this function is only supported in Allwinner Linux-3.4.y
Visit this link download link to download files
After OS is loaded login from a terminal and run the following commands:

$ sudo apt-get install mpv
$ video_play mpv ./big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

In our test it could do hard coding and play 1080P video fluently.

7 Work with FriendlyCore

7.1 Introduction

FriendlyCore is a light Linux system without X-windows, based on ubuntu core, It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

• Change to root

$ su root

• Check device list

$ nmcli dev

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

• Start WiFi

$ nmcli r wifi on

• Scan Surrounding WiFi Sources

$ nmcli dev wifi

• Connect to a WiFi Source

$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

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

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:

$ apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.

7.8 Ethernet Connection

If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP refer to: Use NetworkManager to configure network settings。

7.9 WiringPi and Python Wrapper

• RPi.GPIO : NanoPi NEO/NEO2/Air GPIO Programming with Python

7.10 Custom welcome message

The welcome message is printed from the script in this directory：

/etc/update-motd.d/

For example, to change the FriendlyELEC LOGO, you can change the file /etc/update-motd.d/10-header. For example, to change the LOGO to HELLO, you can change the following line：

TERM=linux toilet -f standard -F metal $BOARD_VENDOR

To:

TERM=linux toilet -f standard -F metal HELLO

7.11 Modify timezone

For exampe, change to Shanghai timezone:

sudo rm /etc/localtime
sudo ln -ls /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

7.12 Set Audio Device

If your system has multiple audio devices such as HDMI-Audio, 3.5mm audio jack and I2S-Codec you can set system's default audio device by running the following commands.

• After your board is booted run the following commands to install alsa packages:

$ apt-get update
$ apt-get install libasound2
$ apt-get install alsa-base
$ apt-get install alsa-utils

• After installation is done you can list all the audio devices by running the following command. Here is a similar list you may see after you run the command:

$ aplay -l
card 0: HDMI
card 1: 3.5mm codec
card 2: I2S codec

"card 0" is HDMI-Audio, "card 1" is 3.5mm audio jack and "card 2" is I2S-Codec. You can set default audio device to HDMI-Audio by changing the "/etc/asound.conf" file as follows:

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

If you change "card 0" to "card 1" the 3.5mm audio jack will be set to the default device.
Copy a .wav file to your board and test it by running the following command:

$ aplay /root/Music/test.wav

You will hear sounds from system's default audio device.
If you are using H3/H5/H2+ series board with mainline kernel, the easier way is using npi-config。

7.13 Connect to DVP Camera CAM500B

For NanoPi-M1 the CAM500B can work with both Linux-3.4 Kernel and Linux-4.14 Kernel.
The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to Matrix - CAM500B.

connect your board to camera module. Then boot OS, connect your board to a network, log into the board as root and run "mjpg-streamer":

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

You need to change the start.sh script and make sure it uses a correct /dev/videoX node. You can check your camera's node by running the following commands:

$ apt-get install v4l-utils
$ v4l2-ctl -d /dev/video0 -D
Driver Info (not using libv4l2):
        Driver name   : sun6i-video
        Card type     : sun6i-csi
        Bus info      : platform:camera
        Driver version: 4.14.0
	...

The above messages indicate that "/dev/video0" is camera's device node.The mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:

 
$ ./start.sh

Here are some details for mjpg_streamer's major options:
-i: input device. For example "input_uvc.so" means it takes input from a camera;
-o: output device. For example "output_http.so" means the it transmits data via http;
-d: input device's subparameter. It defines a camera's device node;
-y: input device's subparameter. It defines a camera's data format: 1:yuyv, 2:yvyu, 3:uyvy 4:vyuy. If this option isn't defined MJPEG will be set as the data format;
-r: input device's subparameter. It defines a camera's resolution;
-f: input device's subparameter. It defines a camera's fps. But whether this fps is supported depends on its driver;
-q: input device's subparameter. It defines the quality of an image generated by libjpeg soft-encoding;
-n: input device's subparameter. It disables the dynctrls function;
-fb: input device's subparameter. It specifies whether an input image is displayed at "/dev/fbX";
-w: output device's subparameter. It defines a directory to hold web pages;

In our case the board'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:

The mjpg-streamer utility uses libjpeg to software-encode steam data. The Linux-4.14 based ROM currently doesn't support hardware-encoding. If you use a H3 boards with Linux-3.4 based ROM you can use the ffmpeg utility to hardware-encode stream data and this can greatly release CPU's resources and speed up encoding:

$ 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. Typing "q" stops video recording. After recording is stopped a test.mp4 file will be generated.

7.14 Connect to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera. Connect your board to camera module. Then boot OS, connect your board to a network, log into the board as root and run "mjpg-streamer":

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

You need to change the start.sh script and make sure it uses a correct /dev/videoX node. You can check your camera's node by running the following commands:

$ apt-get install v4l-utils
$ v4l2-ctl -d /dev/video0 -D
Driver Info (not using libv4l2):
        Driver name   : uvcvideo
        Card type     : HC 3358+2100: HC 3358+2100  / USB 2.0 Camera: USB 2.0 Camera
        Bus info      : usb-1c1b000.usb-1
	...

The above messages indicate that "/dev/video0" is camera's device node.The mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:

 
$ ./start.sh
 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

start.sh runs the following two commands:

export LD_LIBRARY_PATH="$(pwd)"
./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -y 1 -r 1280x720 -f 30 -q 90 -n -fb 0" -o "./output_http.so -w ./www"

Here are some details for mjpg_streamer's major options:
-i: input device. For example "input_uvc.so" means it takes input from a camera;
-o: output device. For example "output_http.so" means the it transmits data via http;
-d: input device's subparameter. It defines a camera's device node;
-y: input device's subparameter. It defines a camera's data format: 1:yuyv, 2:yvyu, 3:uyvy 4:vyuy. If this option isn't defined MJPEG will be set as the data format;
-r: input device's subparameter. It defines a camera's resolution;
-f: input device's subparameter. It defines a camera's fps. But whether this fps is supported depends on its driver;
-q: input device's subparameter. It defines the quality of an image generated by libjpeg soft-encoding;
-n: input device's subparameter. It disables the dynctrls function;
-fb: input device's subparameter. It specifies whether an input image is displayed at "/dev/fbX";
-w: output device's subparameter. It defines a directory to hold web pages;

In our case the board'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:

7.15 Check CPU's Working Temperature

You can get CPU's working temperature by running the following command:

$ cpu_freq 
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU1 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU2 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU3 online=1 temp=26548C governor=ondemand freq=624000KHz

This message means there are currently four CPUs working. All of their working temperature is 26.5 degree in Celsius and each one's clock is 624MHz.
Set CPU frequency:

$ cpu_freq -s 1008000
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU1 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU2 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU3 online=1 temp=36702C governor=userspace freq=1008000KHz

7.16 Test Infrared Receiver

Note: Please Check your board if IR receiver exist.
By default the infrared function is disabled you can enable it by using the npi-config utility:

$ npi-config
    6 Advanced Options     Configure advanced settings
        A8 IR              Enable/Disable IR
            ir Enable/Disable ir[enabled]

Reboot your system and test its infrared function by running the following commands:

$ apt-get install ir-keytable
$ echo "+rc-5 +nec +rc-6 +jvc +sony +rc-5-sz +sanyo +sharp +mce_kbd +xmp" > /sys/class/rc/rc0/protocols   # Enable infrared
$ ir-keytable -t
Testing events. Please, press CTRL-C to abort.

"ir-keytable -t" is used to check whether the receiver receives infrared signals. You can use a remote control to send infrared signals to the receiver. If it works you will see similar messages as follows:

1522404275.767215: event type EV_MSC(0x04): scancode = 0xe0e43
1522404275.767215: event type EV_SYN(0x00).

8 Work with OpenWrt

8.1 Introduction

OpenWrt is a highly extensible GNU/Linux distribution for embedded devices.Unlike many other distributions for routers, OpenWrt is built from the ground up to be a full-featured, easily modifiable operating system for embedded devices. In practice, this means that you can have all the features you need with none of the bloat, powered by a modern Linux kernel. For more details you can refer to:OpenWrt Website.

8.2 System Login

• Login via Serial Port

When you do kernel development you'd better get a serial communication board. After you connect your board to a serial communication board you will be able to do development work from a commandline utility.
Here is a hardware setup:
After you connect your board to a serial communication board (e.g. FriendlyElec's serial communication board) you can power the whole system from either the DC port on the serial communication board or the MicroUSB port(if there is one) on your board:

or you can use a USB to serial board and power on the whole system at the MicroUSB port with a 5V/2A power:

By default you will login as root without a password. You can use "passwd" to set a password for root.

On first boot the system will automatically extend the file system on the TF card to the max capacity:

Please wait for this to be done.

• Login via SSH

In FriendlyElec's OpenWrt system the Ethernet(eth0) is configured as WAN.
Before power on your board make sure your board is connected to a master router's LAN with an Ethernet cable and the eth0 will be assigned an IP address by DHCP.
For example, if your eth0 is assigned an IP address 192.168.1.163 you can login with SSH by running the following command:

$ ssh root@192.168.1.163

You can login without a password.

• Login via Web

You can login OpenWrt via a LuCI Web page.
After you go through all the steps in <Login via SSH> and get an IP address e.g. 192.168.1.163 for the Ethernet connection, type this IP address in a browser's address bar and you will be able to login OpenWrt-LuCI:

By default you will login as root without a password, just click on "Login" to login.

8.3 Manage Software Packages

OpenWrt has a package management utility: opkg. You can get its details by running the following command:

$ opkg
Package Manipulation:
        update                  Update list of available packages
        upgrade <pkgs>          Upgrade packages
        install <pkgs>          Install package(s)
        configure <pkgs>        Configure unpacked package(s)
        remove <pkgs|regexp>    Remove package(s)
        flag <flag> <pkgs>      Flag package(s)
         <flag>=hold|noprune|user|ok|installed|unpacked (one per invocation)
 
Informational Commands:
        list                    List available packages
        list-installed          List installed packages
        list-upgradable         List installed and upgradable packages
        list-changed-conffiles  List user modified configuration files
        files <pkg>             List files belonging to <pkg>
        search <file|regexp>    List package providing <file>
        find <regexp>           List packages whose name or description matches <regexp>
        info [pkg|regexp]       Display all info for <pkg>
        status [pkg|regexp]     Display all status for <pkg>
        download <pkg>          Download <pkg> to current directory
...

These are just part of the manual. Here are some popular opkg commands.

• Update Package List

Before you install a package you'd better update the package list:

$ opkg update

• Check Available Packages

$ opkg list

At the time of writing there are 3241 packages available.

• Check Installed Packages:

$ opkg list-installed

At the time of writing 124 packages have been installed.

• Install/Delete Packages:

$ opkg install <pkgs>
$ opkg remove <pkgs>

• Check Files Contained in Installed Packages:

$ opkg files <pkg>

• Install Chinese Language Package for LuCI

$ opkg install luci-i18n-base-zh-cn

• Check Changed Files:

$ opkg list-changed-conffiles

  • openwrt opkg

8.4 Check System Status

• Check CPU Temperature & Frequency via Commandline

$ cpu_freq 
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU1 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU2 online=1 temp=26548C governor=ondemand freq=624000KHz
        CPU3 online=1 temp=26548C governor=ondemand freq=624000KHz

These messages mean that there are four CPU cores working online simultaneously. Each core's temperature is 26.5 degrees in Celsius, the scheduling policy is on-demand and the working frequency is 624MHz. You can set the frequency by running the following command:

$ cpu_freq -s 1008000
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU1 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU2 online=1 temp=36702C governor=userspace freq=1008000KHz
        CPU3 online=1 temp=36702C governor=userspace freq=1008000KHz

These messages mean four CPU cores are working online. Each core's temperature is 26.5 degrees. Each core's governor is on demand and the frequency is 480 MHz.

• Check System Status on OpenWrt-LuCI Web Page

After open the OpenWrt-LuCI page, go to "Statistics ---> Graphs" and you will see various system statistics e.g.:
1) System Load:

2) RAM:

3) CPU Temperature:

All the statistics listed on the Statistics page are presented by the luci-app-statistics package which uses the Collectd utility to collect data and presents them with the RRDtool utility.
If you want to get more statistics you can install other collectd-mod-* packages. All collectd-mod-* packages use the same configuration file: /etc/config/luci_statistics.

• Reference Links:
  • openwrt luci_app_statistics
  • openwrt statistics.chart.public
  • openwrt statistic.custom

8.5 Check Network->Interfaces Configurations

• After open the OpenWrt-LuCI page, go to "Network" ---> "Interfaces" and you will see the current network's configurations:
  

• All the configurations listed on the Network->Interfaces page are stored in the "/etc/config/network" file.
  

8.6 USB WiFi

Currently the NanoPi NEO2 Black only works with a RTL8821CU USB WiFi dongle, plug and play. After this module is connected to the board it will by default work under AP mode and the hotspot's name is "rtl8821cu-mac address" and the password is "password";

8.7 Huawei's WiFi 2 mini(E8372H-155) Module

After this module is connected to the board it will be plug and play. The hotspot's name is "HUAWEI-8DA5". You can connect a device to the internet by connecting to this hotspot.

9 Make Your Own Linux System

9.1 Make Image Based on Linux-4.14 BSP

The NanoPi M1 supports the Linux-4.14 kernel which is mainly maintained and supported by open source communities. FriendlyElec ported this kernel to the NanoPi M1.
Here is a reference link to more details about how to make image files for Allwinner H3 based on mainline U-boot and Linux-4.14:Building U-boot and Linux for H5/H3/H2+

9.2 Make Image Based on Linux-3.4 BSP

The Linux3.4 BSP is provided by Allwinner. FriendlyElec ported this to the NanoPi M1.

9.2.1 Preparations

Get lichee source:

$ git clone https://github.com/friendlyarm/h3_lichee.git lichee --depth 1

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.

9.2.2 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.

9.2.3 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

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

$ cd lichee/fa_tools
$ ./build.sh -b nanopi-m1 -p linux -t all

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 you compile the source code it will automatically call this cross-compiler.
