4 Get Started

4.1 Essentials You Need

Before play with your NanoPi 2 Fire please get the following items ready

NanoPi 2 Fire
microSD Card/TFCard: Class 10 or Above, minimum 8GB SDHC
microUSB power. A 5V/2A power is a must
HDMI monitor or LCD
USB keyboard and mouse
A Host running Ubuntu 14.04 64 bit system

4.2 TF Card We Tested

To make your NanoPi 2 Fire 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 TF128G MicroSDXC TF 128G Class10 48MB/S:

川宇 8G C10 High Speed class10 micro SD card：

4.3 Make an Installation MicroSD Card

4.3.1 Under Windows

Please get the following files from here:download link to download image files:

For LCD or HDMI output please use the following files:
nanopi2-debian-sd4g.img.zip	Debian image files
nanopi2-android-sd4g.img.zip	Android image files
Flash Utility:
win32diskimager.rar	Windows utility. Under Linux users can use "dd"

Please uncompress these files. Insert an SD card(at least 4G) to a Windows PC, run the win32diskimager utility as administrator，On the utility's main window select your SD card's drive and the image files and click on "write" to start flashing the SD card.
Please insert this card to your NanoPi 2 Fire and power on (with a 5V/2A power source). If the green LED is on and the blue LED is blinking this indicates your NanoPi 2 Fire is successfully booted.

4.3.2 Under Linux Desktop

1) Insert your microSD card to your host running Ubuntu and check your SD card's device name

dmesg | tail

Search the messages output by "dmesg" for similar words like "sdc: sdc1 sdc2". If you can find them it means your SD card is recognized as "/dev/sdc". Or you can check that by commanding "cat /proc/partitions".

2) Download Firmware Package

git clone https://github.com/friendlyarm/sd-fuse_nanopi2.git
cd sd-fuse_nanopi2

3) Flash Android Firmware to MicroSD Card

su
./fusing.sh /dev/sdx

(Note: you need to replace "/dev/sdx" with the device name in your system) When you do “git clone” you have to hit “Y” within 10 seconds after it prompts you to download image files otherwise you will miss the download.

4) Flash Debian Firmware to MicroSD Card

./fusing.sh /dev/sdx debian

4.3.3 Extend NanoPi 2's TF Card Section

4.3.3.1 For Debian

Please run the following commands on a PC host's terminal:

sudo umount /dev/sdx? 
sudo parted /dev/sdx unit % resizepart 2 100 unit MB print
sudo resize2fs -f /dev/sdx2

4.3.3.2 For Android

Please run the following commands on a PC host's terminal:

sudo umount /dev/sdx?
sudo parted /dev/sdx unit % resizepart 4 100 resizepart 7 100 unit MB print
sudo resize2fs -f /dev/sdx7

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

4.3.4 LCD/HDMI Resolution

When system boots our uboot will check whether it is connected to an LCD. If it recognizes an LCD it will configure its resolution. By default our uboot configures the display to HDMI 720P.
If you want to reset the LCD resolution you can modify file "arch/arm/plat-s5p4418/nanopi2/lcds.c" in the kernel and recompile it.
If your NanoPi 2 connects an HDMI monitor and it runs Android it will automatically set the resolution to an appropriate HDMI mode by checking "EDID". If your NanoPi 2 connects an HDMI monitor and it runs Debian by default it will set the resolution to HDMI 720P and in this case you can set it to 1080P by modifying your kernel's configuration.

4.4 Update Image Files in MicroSD Card From PC Host

If you want to make some changes to the image files in your MicroSD card please follow steps below otherwise you can skip this section.
Please insert your MicroSD card to a PC host running LINUX, mount the boot and rootfs sections of the SD card and follow the steps below:

1) If you want to change your kernel command line parameters you can do it via the fw_setevn utility under "sd-fuse_nanopi2/tools"
Check the current Command Line:

cd sd-fuse_nanopi2/tools
./fw_printenv /dev/sdc | grep bootargs

Android 5.1.1_r6 starts SELinux. By default it is enforcing. You can change it this way:

./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive

This will set it to "permissive". The "XXX" stands for the original bootargs' value.

2) Update Kernel
Our customized uboot will check the LCD type when it boots.For a non-Android OS If it recognizes an LCD connected to the NanoPi 2 Fire it will load "uImage" from "boot" otherwise it will load "uImage.hdmi"
However for Android these two files don't make any differences for whatever display device it detects. You can use your generated uImage to replace the existing one under "boot".
For Debian if your generated kernel is for LCD you need to replace the existing uImage or if your kernel is for HDMI you need to replace the existing uImage.hdmi .

4.5 Run Android or Debian

Insert a MicroSD card with Android image files to your NanoPi 2 Fire, connect the NanoPi 2 Fire to an HDMI monitor and a 5V/2A power source the NanoPi 2 Fire will be automatically powered on. If you can see the blue LED flashing it means your board is working and you will see Android loading on the HDMI monitor.

1) If you connect the NanoPi 2 Fire to an HDMI monitor you need to use a USB mouse and a USB keyboard to operate. If you connect it to an LCD with capacitive touch you can operate directly on the LCD. 2）If you want to do kernel development you'd better have a serial board which allows you to operate the board via a serial terminal.

Here is a case in which we connect a NanoPi 2 Fire to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal:
Under Debian the password for "root" is "fa".

4.6 Login Debian via VNC or SSH

If your NanoPi 2 Fire is not connected to a display device you can download and install a "VNC Viewer" on your PC or mobile phone and login the NanoPi 2 Fire via VNC. Its default password is "fa123456". Here is a screenshot which shows how it looks like when users login the NanoPi 2 Fire from an iPhone via VNC:

You can login via "SSH -l root 192.168.8.1" too and the default password for "root" is "fa".

5 Play with Debian

5.1 Ethernet Connection

If the NanoPi 2 Fire is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it is powered on. 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.

1) Setup MAC Address

The NanoPi 2 Fire by default doesn't have a valid MAC address. If the board connects a network successfully it will automatically generates a random MAC in "/etc/network/interfaces.d/eth0". Users can change it to a self-defined valid one:

vi /etc/network/interfaces.d/eth0

Here is the content of a sample configuration file:

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
hwaddress 76:92:d4:85:f3:0f

The "hwaddress" specifies the MAC address. Here the "76:92:d4:85:f3:0f" is a random MAC. We suggest users change it to a valid one
Note: when you reset the MAC please make sure your MAC meets IEEE's definition otherwise it will cause unexpected issues.
After you make your change, save, exit and reboot your board or run the following commands to restart the network:

systemctl restart networking

5.2 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 Make Your Own OS Image

6.1 Setup Development Environment

6.2 Install Cross Compiler

Please download the compiler package:

git clone https://github.com/friendlyarm/prebuilts.git
sudo mkdir -p /opt/FriendlyARM/toolchain
sudo tar xf prebuilts/gcc-x64/arm-cortexa9-linux-gnueabihf-4.9.3.tar.xz -C /opt/FriendlyARM/toolchain/

Then add the compiler's directory to "PATH" by appending the following lines in "~/.bashrc":

export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH
export GCC_COLORS=auto

Execute "~/.bashrc" to make the changes into effect. Please note that there is a space after ".":

. ~/.bashrc

This compiler is a 64-bit one therefore it cannot be run on a 32-bit LINUX. After the compiler is installed you can verify it by running the following commands:

arm-linux-gcc -v
Using built-in specs.
COLLECT_GCC=arm-linux-gcc
COLLECT_LTO_WRAPPER=/opt/FriendlyARM/toolchain/4.9.3/libexec/gcc/arm-cortexa9-linux-gnueabihf/4.9.3/lto-wrapper

...
Thread model: posix
gcc version 4.9.3 (ctng-1.21.0-229g-FA)

6.3 Compile U-Boot

Download the U-Boot source code and compile it. Please note the github's branch is nanopi2-lollipop-mr1:

git clone https://github.com/friendlyarm/uboot_nanopi2.git
cd uboot_nanopi2
git checkout nanopi2-lollipop-mr1
make s5p4418_nanopi2_config
make CROSS_COMPILE=arm-linux-

After your compilation succeeds a u-boot.bin will be generated. If you want to test it please flash it to your installation MicroSD card via fastboot. Here is how you can do it:
1) On your PC host please run "sudo apt-get install android-tools-fastboot" to install the fastboot utility
2) Connect your NanoPi 2 Fire to your PC host via a serial cable (e.g. PSU-ONECOME). Press the enter key within two seconds right after you power on your NanoPi 2 Fire and you will enter uboot's command line mode:
3) After type "fastboot" and press "enter" you will enter the fastboot mode:
4) Connect your NanoPi 2 Fire to this PC host via a microUSB cable and type the following command to flash the u-boot.bin:

fastboot flash bootloader u-boot.bin

Warning: you cannot update this MicroSD card by commanding "dd". This command which will cause trouble when booting the NanoPi 2 Fire.

6.4 Prepare mkimage

You need the mkimage utility to compile a U-Boot source code package. Please make sure this utility works well on your host before you start compiling a uImage.
You can install this utility by either commanding "sudo apt-get install u-boot-tools" or following the commands below:

cd uboot_nanopi2
make CROSS_COMPILE=arm-linux- tools
sudo mkdir -p /usr/local/sbin && sudo cp -v tools/mkimage /usr/local/sbin

6.5 Compile Linux kernel

6.5.1 Compile Kernel

Download Kernel Source Code

git clone https://github.com/friendlyarm/linux-3.4.y.git
cd linux-3.4.y
git checkout nanopi2-lollipop-mr1

The NanoPi 2 Fire's kernel source code lies in the "nanopi2-lollipop-mr1" branch.

Compile Android Kernel

make nanopi2_android_defconfig
touch .scmversion
make uImage

Compile Debian Kernel

make nanopi2_linux_defconfig
touch .scmversion
make uImage

After your compilation succeeds a uImage will be generated in the "arch/arm/boot/uImage" directory. This kernel is for HDMI. You can use it to replace the existing uImage.hdmi
If you want to generate a kernel for LCD you can do it this way:

touch .scmversion
make nanopi2_linux_defconfig
make menuconfig
  Device Drivers -->
    Graphics support -->
      Nexell Graphics -->
        [*] LCD
        [ ] HDMI
make uImage

After your compilation succeeds a uImage will be generated for LCD. You can use it to replace the existing uImage.

6.5.2 Compile Kernel Modules

Android contains kernel modules which are in the "/lib/modules" directory in the system section. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.
Compile Original Kernel Modules:

cd linux-3.4.y
make CROSS_COMPILE=arm-eabi- modules

Here we have two new modules and we can compile them by following the commands below:

cd /opt/FriendlyARM/s5p4418/android
./vendor/friendly-arm/build/common/build-modules.sh

The "/opt/FriendlyARM/s5p4418/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".
After your compilation succeeds new modules will be generated

6.6 Compile Android

Install Cross Compiler

We recommend installing 64 bit Ubuntu 14.04 on your PC host.

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex libncurses5-dev zlib1g-dev gawk minicom

For more details please refer to https://source.android.com/source/initializing.html 。

Download Source Code

You need to use repo to get the Android source code. Please refer to https://source.android.com/source/downloading.html 。

mkdir android && cd android
repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi2-lollipop-mr1
repo sync

The "android" directory is the working directory.

Compile System Package

source build/envsetup.sh
lunch aosp_nanopi2-userdebug
make -j8

After your compilation succeeds an image will be generated in the "out/target/product/nanopi2/" directory.

7 Connect NanoPi 2 Fire to External Modules

7.1 Connect NanoPi 2 Fire to USB Camera(FA-CAM202)

In this usecase the NanoPi 2 Fire runs Debian. If you connect your NanoPi 2 Fire to our LCD after Debain is fully loaded please click on "other"-->"xawtv9" on the left bottom of the GUI and the USB Camera application will be started. After enter "welcome to xawtv！" please click on "OK" to start exploring.

7.2 Connect NanoPi 2 Fire to CMOS 5M-Pixel Camera

In this usecase the NanoPi 2 Fire runs Android5.1. If you connect your NanoPi 2 Fire to our LCD after Debain is fully loaded please click on the "Camera" icon the application will be started.

7.3 Use OpenCV to Access USB Camera

The full name of "OpenCV" is Open Source Computer Vision Library and it is a cross platform vision library.
When the NanoPi 2 Fire runs Debian users can use OpenCV APIs to access a USB Camera device

Here is a guideline on how to use OpenCV with C++ on the NanoPi 2 Fire
1. Preparations

---Firstly you need to make sure your NanoPi 2 Fire is connected to the internet. 
   Login your NanoPi 2 Fire via a serial terminal or SSH. After login please type your username(root) and password(fa):
---Run the following commands:

#apt-get update
 (The OS images we provide for the NanoPi 2 Fire by default have the vi utility. However we suggest you install the vim utility)
#apt-get install vim
#apt-get install libcv-dev libopencv-dev

2. Make sure your USB camera works with the NanoPi 2 Fire. You can test your camera with NanoPi 2 Fire's camera utility.

3. Check your camera device:

#ls /dev/video + "Tab" key (This lists available USB camera devices. In our test case video9 was available and video0 to video8 were occupied)

4. OpenCV's code sample:

#cd /home/fa
#vim test.cpp

#include "opencv2/opencv.hpp"
 
using namespace cv;
 
int main(int, char**)
{
    VideoCapture cap(0); // open the default camera
    if(!cap.isOpened())  // check if we succeeded
        return -1;
 
    Mat edges;
    namedWindow("edges",1);
    for(;;)
    {
        Mat frame;
        cap >> frame; // get a new frame from camera
        cvtColor(frame, edges, CV_BGR2GRAY);
        GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5);
        Canny(edges, edges, 0, 30, 3);
        imshow("edges", edges);
        if(waitKey(30) >= 0) break;
    }
    // the camera will be deinitialized automatically in VideoCapture destructor
    return 0;
}

Compile the code sample:

#g++ test.cpp -o test -lopencv_core -lopencv_highgui -lopencv_imgproc

If it is compiled successfully a "test" executable will be generated:
5. Note: the NanoPi 2 Fire has nine video devices. However this OpenCV's code sample defines a maximum of 8 cameras can be accessed therefore one video needs to be removed. Here we removed video0

#rm /dev/video0
#mv /dev/video9 /dev/video0

6. Connect NanoPi 2 Fire to USB Keyboard & Run the Following Command:

#./test

This is what you expect to observe:
