4.3 Make an Installation TF Card

4.3.1 Get Image Files

Visit this link download link to download image files and the flashing utility:

Image Files
nanopi-m1-debian-sd4g.img.zip Debian Image File
nanopi-m1-android.img.zip Android Image File
Flash Utility:
win32diskimager.rar Windows utility for flashing Debian image. Under Linux users can use "dd"
PhoenixCard_V310.rar Windows utility for flashing Android image. Attention: the "dd" command under Linux doesn't work for flashing Android image
HDDLLF.4.40.exe Windows utility for formatting a TF card

4.3.2 Make Debian Image Card

  • Uncompress the nanopi-m1-debian-sd4g.img.zip and win32diskimager.rar files. Insert a TF card(at least 4G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your TF card's drive, the wanted image file and click on "write" to start flashing the TF card.
  • Insert this card into your NanoPi M1's BOOT slot 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 M1 has successfully booted.


4.3.3 Make Android Image Card

  • On a Windows PC run the HDDLLF.4.40 utility as administrator. Insert a TF card(at least 4G) into this PC and format it. After formatting is done take out the TF card, insert it into the PC again and format it with Windows internal format utility to format it to FAT32. After this formatting is done take out the card.
  • Uncompress the nanopi-m1-android.img.zip and PhoenixCard_V310.rar files. Insert the TF card you made in the previous step into a Windows PC and run the PhoenixCard_V310 utility as administrator. On the utility's main window select your TF card's drive, the wanted image file and click on "write" to start flashing the TF card.
  • Insert this card into your NanoPi M1's BOOT slot 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 M1 has successfully booted.

Note: you must format your TF card before you start making it an Android image card.

5 Working with Debian

5.1 Run Debian

  • Insert a TF card with Debian image files into your NanoPi M1, connect the NanoPi M1 to an HDMI monitor and a 5V/2A power source the NanoPi M1 will be automatically powered on. If you can see the blue LED flashing it means your board is working and you will see Debain being loaded on the HDMI monitor.

1）If you connect the NanoPi M1 to an HDMI monitor you need to use a USB mouse and a USB keyboard to operate.
2) 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 NanoPi M1 to a PC via the PSU-ONECOM and you can power on your M1 from either the PSU-ONECOM or M1's MicroUSB:

PSU-ONECOM-M1

  • The password for "root" is "fa".
  • Update packages
sudo apt-get update

5.2 Extend TF Card's rootfs Section

We strongly recommend you to do this right after you have made an installation TF card since this will greatly enhance your M1's experience.
Insert your TF card into a host PC and run the following commands on your PC's terminal: 

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

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

  • If you want to resize the rootfs section of the TF card run the following commands on the NanoPi M1's Debian terminal:
sudo fs_resize

Following the prompt type in "y" to start re-sizing the file system and a second "y" to reboot the M1. After the M1 is rebooted check the new section by using the following command： 

df -h

5.3 Ethernet Connection

If the NanoPi M1 is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it is 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

  • Setup MAC Address

The NanoPi M1 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

5.4 Login to Debian via VNC and SSH

If your NanoPi M1 is not connected to a display device you can login to your NanoPi M1 from a mobile phone. You need to download and install a "VNC Viewer" from here on a mobile phone and login to the NanoPi M1 via VNC at port 1. Its default password is "fa123456".
Here is a screenshot which shows how it looks like when users login to the NanoPi M1 from an iPhone via VNC:
VNC to NanoPi2
You can login via "SSH -l root 192.168.8.1" and the default password for "root" is "fa". You need to replace "192.168.8.1" with your actual IP address.

5.5 HDMI Resolution

Our Debian system's HDMI resolution is set by a script.bin file in the root directory of the installation TF card's boot section. By default the resolution is 1080P60. There are multiple script.bin files under that directory for different resolutions. For example if you want to modify the resolution to 720P60 you can use the script-720p-60.bin file to replace the existing one by using the following command: 

# in TF card boot partition
cp script/script-720p-60.bin ./script.bin

5.6 HDMI Audio Output

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.

5.7 Test GPU

After Debian loads please login from a terminal and run "glmark2-es2": 

glmark2-es2

m1-gpu-glmark2

5.8 Test VPU

Visit this link download link to download files
After Debian is loaded login from a terminal and run "mplayer": 

mplayer -vo vdpau -vc ffmpeg12vdpau,ffh264vdpau, ./big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

In our test it could do hard coding and play 1080P video fluently.

5.9 Test USB WiFi

Our Debian system has support for popular USB WiFi drivers. Many USB WiFi modules are plug and play with our system. Here is a list of models we tested;

Number Model
1 RTL8188CUS 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601

After you connect your USB WiFi to the M1, if it cannot find an AP, remove it, reconnect it and click on "refresh" on the wicd network manager to try again. If your USB WiFi model is not in the list refer to Matrix_-_USB_WiFi on how to proceed.

5.10 Connect NanoPi M1 to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera.
In this use case the NanoPi M1 runs Debian. Connect your NanoPi M1 to an HDMI monitor. After Debain is fully loaded open a terminal and run the following command: 

xawtv 0

You will be able to preview with your camera Note: "0" in our case stands for the camera's device name "/dev/video0". You need to use your camera's index in this command.

5.11 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.
  • Make sure your NanoPi M1 is connected to the internet and an HDMI monitor. Boot Debian on the NanoPi M1 and login
  • Install OpenCV libraries:
apt-get update
apt-get install libcv-dev libopencv-dev
  • Connect a USB camera to the NanoPi M1 and run the following command:
xawtv 0
  • Compile and run a code sample（Official Code Sample in C++ provided by the OpenCV organization):
cd /home/fa/Documents/opencv-demo
make
./demo

Here is what you expect to observe:
OpenCV-M1

5.12 Check CPU's Working Temperature

You can use the following command to read H3's temperature and frequency 

cpu_freq

6 Make Your Own Debian

Visit this link [1] and enter the sources directory to download the nanopi-H3-bsp source code.Use the 7-zip utility to uncompress it and a lihee directory and an Android directory will be generated. Or you can get it from our github: 

git clone https://github.com/friendlyarm/h3_lichee.git lichee

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.

6.1 Compile lichee Source Code

Compilation of the H3'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 un the following command to compile the whole package: 

cd lichee
./build.sh -p sun8iw7p1 -b nanopi-h3

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

6.2 Package System Modules

./build.sh pack

This command copies the generated executables including u-boot and Linux kernel and configuration files to the "lichee/tools/pack/out/" directory and generates a script.bin.
The script.bin file is designed by Allwinner for its CPUs. For more details refer to script.bin。

6.3 Compile U-boot

./build.sh -p sun8iw7p1 -b nanopi-h3 -m uboot

After a u-boot executable is generated some extra patches need to be patched to it. Run "./gen_script.sh" to patch this executable.
If you want to manually patch the executable refer to H3_Manual_build_howto and run the following commands to update the u-boot in the TF card: 

./fuse_uboot.sh /dev/sdx

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

6.4 Compile Linux Kernel

If you want to compile the Linux kernel run the following command: 

./build.sh -p sun8iw7p1 -b nanopi-h3 -m kernel

After the compilation is done a uImage and its kernel modules will be generated under "linux-3.4/output".

6.5 Clean Source Code

./build.sh -p sun8iw7p1 -b nanopi-h3 -m clean
