  • After flash is done take out the MicroSD to eMMC adapter. Take the eMMC module off the adapter, insert this module to the board's eMMC slot and power up the board. If the PWR LED is solid on and the STAT LED is flashing it means your board has been successfully booted.
  • When both an SD card and an eMMC module are connected to a board the board will be booted from the SD card first and if that fails it will be booted from eMMC.

Work with FriendlyCore


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.

Besides the regular Ubuntu core's features our FriendlyCore has the following additional features:

  • it supports our LCDs with both capacitive touch and resistive touch(S700, X710, HD702, S430, HD101 and S70)
  • it supports WiFi
  • it supports Ethernet
  • it supports Bluetooth and has been installed with bluez utilities
  • it supports audio playing
  • it supports Qt5.9 EGLES and OpenGL ES1.1/2.0 (Only for S5P4418/S5P6818)

FriendlyCore's User Accounts

  • If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
  • 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 board to a PC via the PSU-ONECOM and you can power on your board from either the PSU-ONECOM or its MicroUSB:

For example, NanoPi-M1:
You can use a USB to Serial conversion board too.
Make sure you use a 5V/2A power to power your board from its MicroUSB port:
For example, NanoPi-M1:

  • FriendlyCore User Accounts:

Non-root User:

   User Name: pi
   Password: pi


   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

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:

Develop Qt Application

Please refer to: How to build Qt application

Setup Program to AutoRun

You can setup a program to autorun on system boot with npi-config:

sudo npi-config

Go to Boot Options -> Autologin -> Qt/Embedded, select Enable and reboot.

Extend TF Card's Section

When FriendlyCore 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


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

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:

  • 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 it 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" 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:

$ sudo apt-get install linux-firmware

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

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

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

Connect to DVP Camera CAM500B

For H3 based boards the CAM500B can work with both Linux-3.4 Kernel and Linux-4.14 Kernel.
For H5 based boards the CAM500B can work with 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 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
$ ./

You need to change the 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 CAM500B'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:

$ ./
 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 runs the following two commands:

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

Here are some details for mjpg_streamer's major options:
-i: input device. For example "" means it takes input from a camera;
-o: output device. For example "" 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 We typed 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.

Connect to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera. You can refer to <Connect DVP Camera (CAM500B) to Board> on how to connect a USB camera to a board.
You need to change the script and make sure it uses a correct /dev/videoX node. You can check your FA-CAM202's node by running the following commands:

$ apt-get install v4l-utils
$ v4l2-ctl -d /dev/video1 -D
Driver Info (not using libv4l2):
        Driver name   : uvcvideo
        Card type     : HC 3358+2100: HC 3358+2100
        Bus info      : usb-1c1b000.usb-1

Information above indicates that /dev/video1 is the device node of the FA-CAM 202.

Check CPU's Working Temperature with Commandline Utility

You can get CPU's working temperature by running the following command in a commandline utility:

$ cpu_freq
CPU0 online=1 temp=26581 governor=ondemand cur_freq=480000
CPU1 online=1 temp=26581 governor=ondemand cur_freq=480000
CPU2 online=1 temp=26581 governor=ondemand cur_freq=480000
CPU3 online=1 temp=26581 governor=ondemand cur_freq=480000

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 480MHz.

Test Watchdog

You can test watchdog by running the following commands:

$ cd /root/demo/watchdog/
$ gcc watchdog_demo.c -o watchdog_demo
$ ./watchdog_demo /dev/watchdog0 10
Set timeout: 10 seconds
Get timeout: 10 seconds
System will reboot in 10 second

System will reboot in 10 seconds.

Test Infrared Receiver

Note: this only applies to boards(such as NanoPi M1, NanoPi M1 Plus and etc) that have an infrared receiver. If you want to test boards(such as NanoPi NEO, NanoPi NEO Air and etc) that don't have an infrared receiver but have infrared pins you need to connect an infrared module to pin GPIOL11.
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).
1522404278.911267: event type EV_MSC(0x04): scancode = 0xe0e42
1522404278.911267: event type EV_SYN(0x00).

Access GPIO Pins/Wirings with WiringNP

The wiringPi library was initially developed by Gordon Henderson in C. It contains libraries to access GPIO, I2C, SPI, UART, PWM and etc. The wiringPi library contains various libraries, header files and a commandline utility:gpio. The gpio utility can be used to read and write GPIO pins.
FriendlyElec integrated this utility in FriendlyCore system allowing users to easily access GPIO pins. For more details refer to WiringNP WiringNP
