4 Get Started

4.1 Essentials You Need

Before starting to use your NanoPi M2 get the following items ready

  • NanoPi M2
  • 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 computer running Ubuntu 14.04 64 bit system

4.2 TF Cards We Tested

To make your NanoPi M2 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 MicroSD 8G

  • SanDisk TF128G MicroSDXC TF 128G Class10 48MB/S:

SanDisk MicroSD 128G

  • 川宇 8G C10 High Speed class10 micro SD card:

chuanyu MicroSD 8G

4.3 Make an Installation MicroSD Card

4.3.1 Under Windows

Get the following files from here:[https://www.mediafire.com/folder/ilkcy37otd7il/S5P4418 to download image files.

For LCD or HDMI output use the following files:
nanopi2-debian-sd4g.img.zip Debian image files (there are two Debian files)
nanopi2-android-sd4g.img.zip Android image files
Flash Utility:
win32diskimager.rar Windows utility. Under Linux users can use "dd"
  • Uncompress these files. Insert an SD card(at least 4G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your SD card's drive, the wanted image file and click on "write" to start flashing the SD card.
  • Insert this card into your NanoPi M2 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 M2 has successfully booted.

4.3.2 Under Linux Desktop

  • 1) Insert your microSD card into 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 Flashing Script
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 M2'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 the system boots our uboot will check whether it is connected to an LCD or to an HDMI monitor. If it recognizes an LCD it will configure its resolution. Our uboot defaults to the HDMI 720P configuration.
If you want to modify the LCD resolution you can modify file "arch/arm/plat-s5p4418/nanopi2/lcds.c" in the kernel and recompile it.
If your NanoPi M2 is connected an HDMI monitor and it runs Android it will automatically set the resolution to an appropriate HDMI mode by checking the "EDID". If your NanoPi M2 is connected an HDMI monitor and it runs Debian by default it will set the resolution to HDMI 720P. If you want to modify the resolution to 1080P modify your kernel's configuration as explained above.

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 follow steps below otherwise you can skip this section.
Insert your MicroSD card into 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 sets 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 M2 it will load "uImage" from "boot" otherwise it will load "uImage.hdmi".
For Android it doesn't make any difference which display device is detected. You can use your generated uImage to replace the existing one under "boot".
For Debian if your generated kernel is for an 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/Debian image files into your NanoPi M2, connect the NanoPi M2 to an HDMI monitor and a 5V/2A power source the NanoPi M2 will be automatically powered up. If you can see the blue LED flashing it means your board is working and you will see Android/Debain loading on the HDMI monitor.

1）If you connect the NanoPi M2 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 comms board which will allow you to operate the board via a serial terminal.

  • Here is a setup where we connect a NanoPi M2 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal:

PSU-ONECOM-M2

  • Under Debian the password for "root" is "fa".

4.6 Login Debian via VNC or SSH

If your NanoPi M2 is not connected to a display device you can download and install a "VNC Viewer" on your PC or a mobile phone and login to the NanoPi M2 via VNC. Its default password is "fa123456".
Here is a screenshot which shows how it looks like when users login the NanoPi M2 from an iPhone via VNC:
VNC to NanoPi2
You can login via "SSH -l root 192.168.8.1" too and the default password for "root" is "fa"

5 Working with Debian

5.1 Ethernet Connection

If the NanoPi M2 is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it has powered up. 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 M2 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 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".

5.3 HDMI Audio Output/3.5mm Audio Jack Output Under Debian

By default our Debian system's HDMI output doesn't have audio output. To enable the HDMI audio output you need to install the alsa packages
Firstly, make sure your board runs our latest Debian image and is connected to the internet:
After your board is powered up run the following commands: 

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

After the installation is done copy a ".wav" audio file to your NanoPi M2, connect your NanoPi M2 to an HDMI monitor and play it by using the following command: 

aplay music.wav

Our Debian system's default audio output is the 3.5mm audio jack. You can turn on the HDMI audio by editting the /etc/asound.conf file: 

pcm.!default {
    type hw
    card 1
    device 0
}
 
ctl.!default {
    type hw
    card 1
}

card 0 points to the 3.5mm audio jack and card 1 points to the HDMI audio. You need to save your changes and reboot your system to make your changes take effect.

6 Make Your Own OS Image

6.1 Setup Development Environment

Install Cross Compiler: 

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. Note that there is a space after the first ".": 

. ~/.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

6.2 Compile U-Boot

Download the U-Boot source code and compile it. Note that 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 flash it to your installation MicroSD card via fastboot. Here is how you can do it:
1) On your PC host run "sudo apt-get install android-tools-fastboot" to install the fastboot utility;
2) Connect your NanoPi M2 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 M2 and you will enter uboot's command line mode;
3) After type in "fastboot" and press "enter" you will enter the fastboot mode;
4) Connect your NanoPi M2 to this PC host via a microUSB cable and type in 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 will cause trouble when booting the NanoPi M2.

6.3 Prepare mkimage

You need the mkimage utility to compile a U-Boot source code package. 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
