6 Work with FriendlyCore

6.1 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.

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

• it integrates Qt4.8;
• it integrates NetworkManager;
• it has bluez and Bluetooth related packages;
• it has alsa packages;
• it has npi-config;
• it has RPiGPIO, a Python GPIO module;
• it has some Python/C demo in /root/ directory;
• it enables 512M-swap partition;

6.2 System Login

• 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:
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:

• FriendlyCore 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

6.3 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:

6.4 Develop Qt Application

Please refer to: How to Build and Install Qt Application for FriendlyELEC Boards

6.5 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.

6.6 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

6.7 WiFi

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.

6.8 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。

6.9 WiringPi and Python Wrapper

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

6.10 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

6.11 Modify timezone

For exampe, change to Shanghai timezone:

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

6.12 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。

6.13 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 start.sh 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.

6.14 Check CPU's Working Temperature

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

$ 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.

6.15 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.

6.16 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).

7 Make Your Own FriendlyCore

7.1 Mainline U-boot & Linux(64 bit)

Now the NanoPi NEO2 can run a 64-bit Linux kernel with 64-bit Ubuntu Core 16.04. Here is a detailed reference on how to run mainline U-boot and Linux on H5: Mainline U-boot & Linux

7.2 Use Allwinner's BSP

7.2.1 Preparations

Visit this link download link and enter the "sources/nanopi-H5-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 ./
$ lichee

Or you can get it from our github:

$ git clone https://github.com/friendlyarm/h5_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.

7.2.2 Install Cross Compiler

Visit this site download link, enter the "toolchain" directory, download the cross compiler "gcc-linaro-arm-4.6.3.tar.xz" and "gcc-linaro-aarch64.tar.xz" and copy them to the "lichee/brandy/toochain/" directory.
"gcc-linaro-arm-4.6.3.tar.xz"is for compiling u-boot and "gcc-linaro-aarch64.tar.xz" is for compiling Linux kernel.

7.2.3 Compile lichee Source Code

Compilation of the H5'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-neo2 -p linux -t all

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

The following commands can be used to update the u-boot on an installation TF card:

$ cd lichee/fa_tools/
$ ./fuse.sh -d /dev/sdx -p linux -t u-boot

Note: you need to replace "/dev/sdx" with the device name in your system.
The boot.img and kernel modules are under the "linux-3.10/output" directory. You can copy the new boot.img file to your TF card's boot partition.

7.2.4 Compile U-boot

Note:you need to compile the whole lichee directory before you can compile U-boot individually.
You can run the following commands to compile u-boot individually:

$ cd lichee/fa_tools/
$ ./build.sh -b nanopi-neo2 -p linux -t u-boot

7.2.5 Compile Linux Kernel

Note:you need to compile the whole lichee directory before you can compile Linux kernel individually.
You can run the following commands to compile Linux kernel individually:

$ cd lichee/fa_tools/
$ ./build.sh -b nanopi-neo2 -p linux -t kernel

The boot.img and kernel modules are under the "linux-3.10/output" directory. You can copy the new boot.img file to your TF card's boot partition.

7.2.6 Clean Source Code

$ cd lichee/fa_tools/
$ ./build.sh -b nanopi-neo2 -p linux -t clean
