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 recommend 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 Fire's TF Card Section
- When Debian/Ubuntu is loaded the TF card's section will be automatically extended.
- When Android is loaded you need to run the following commands on your host PC to extend your TF card's section:
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:
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:
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 . 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 ".":
