5.3.2 Comparison of Linux-3.4.y and Linux-4.x.y

Our Linux-3.4.y is provided by Allwinner. Allwinner has done a lot of customization work which on one hand contains many features and functions but on the other hand incurs overheat issues;
Our Linux-4.x.y is updated very often. We will keep this kernel with the latest one released by Linus Torvalds. This kernel doesn't generate heat that much and if you don't need to use VPU or GPU you can try this kernel;

Here is a comparison table:

5.3.3 TF Card Systems

5.3.3.1 Make Debian/Ubuntu Image Card

Extract the nanopi-m1-plus_debian-jessie_3.4.y_YYYYMMDD.img.zip and win32diskimager.rar files. Insert a TF card(at least 8G) 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 Plus' 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 Plus has successfully booted.

5.3.3.2 Make Android Image Card

Note:before make a MicroSD card to an Android image card you need to format this card.

On a Windows PC run the HDDLLF.4.40 utility as administrator. Insert a TF card(at least 8G) 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.
Extract the the Android image file and PhoenixCard_V310.rar . 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 Plus' 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 Plus has successfully booted.

5.3.4 Flash image to eMMC with eflasher

Extract the nanopi-m1-plus_eflasher_3.4.y_YYYYMMDD.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 Plus' 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 Plus has successfully booted.
Connect the board to an HDMI monitor or an LCD and a USB mouse, and select an OS to start installation.

If no monitor is connected you can select an OS by running the following command:

$ eflasher

Type a number and enter to select an OS, then type "yes" and enter to start installation:

After installation is done shutdown the system, take out the TF card, power on your board again and it will boot from eMMC.

6 Work with Debian

6.1 Run Debian

Insert a TF card with Debian image into your NanoPi M1 Plus, connect the it to an HDMI monitor and a 5V/2A power it 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 your NanoPi M1 Plus 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 Plus to a PC via the PSU-ONECOM and you can power on your M1 Plus from either the PSU-ONECOM or its MicroUSB:

The password for both "root" and "fa" is "fa" under Debian. All the commands we tested in this section were executed under "root"
Update packages

$ apt-get update

6.2 Extend TF Card's rootfs Section

When you boot OS for the first time with your image card your OS will automatically resize the file system and this process takes a relatively long time.After your OS is fully loaded you can check the file system's size by using the following command:

$ df -h

6.3 Ethernet Connection

If the NanoPi M1 Plus 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. Run the following command to check its MAC address:

$ dhclient eth0

6.4 Wireless Connection

Open the file "/etc/wpa_supplicant/wpa_supplicant.conf" with vi or gedit and append the following lines:

network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}

The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.
Save, exit and run the following commands your board will be connected to your specified WiFi:

$ ifdown wlan0
$ ifup wlan0

If your WiFi password has special characters or you don't want your password saved as plain text you can use "wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:

$ wpa_passphrase YourWiFiESSID

Following the prompt type in your password. If you open the file "/etc/wpa_supplicant/wpa_supplicant.conf" you will find that your password has been updated and you can delete your clear-text password.

You can run the following commands to switch your board's AP6212 WiFi mode to AP :

$ turn-wifi-into-apmode yes
Enter wireless name [default: friendlyelec-wifiap]:
Enter password [default: 123456789]:
Configuration Saved!
 
Please connect your computer to the wireless network:
Wireless Name: friendlyelec-wifiap
     Password: 123456789
done.

Exit AP mode:

$ turn-wifi-into-apmode no

6.5 Login to OS via VNC and SSH

If your NanoPi M1 Plus is not connected to a display device you can login to your NanoPi M1 Plus from a mobile phone or PC. You need to download and install a "VNC Viewer" from here and login to the NanoPi M1 Plus via VNC at port 1. Its default password is "fa123456".
Here is a screenshot which shows how it looks like when users login to a NanoPi M1 Plus from an iPhone via VNC:

If you don't want connect your board to HDMI or a serial board you can log into your board via SSH. If your M1 Plus' IP address is 192.168.1.230 you can run the following command to log in:

$ ssh root@192.168.1.230

The password is fa.

6.6 HDMI Audio Output

Note:this function is only supported in Linux-3.4.7
Our system's default audio output is the 3.5mm audio jack. You can turn on the HDMI audio by editing 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.

6.7 Test GPU

Note:this function is only supported in Linux-3.4.7
Connect your board to an HDMI monitor and After OS is booted login and run the following command: After Debian loads please login from a terminal and run "glmark2-es2":

$ glmark2-es2

6.8 Test VPU

Note:this function is only supported in Linux-3.4.7
Visit this link download link to download the test files under the "test-video" directory
After OS is loaded login from a terminal and run the following commands:

$ apt-get install mpv
$ video_play mpv ./big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

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

6.9 Test USB WiFi

Our 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

If you NanoPi M1 Plus is connected to a USB WiFi and is powered up you can log into M1 Plus and run the following command to check if the USB WiFi is recognized. If "wlan" is listed it indicates your USB WiFi has been recognized:

$ ifconfig -a

We assume the USB WiFi's node is wlan1.
Open the /etc/wpa_supplicant/wpa_supplicant.conf file and append the following lines:

network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}

The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.

Append the following lines in the "/etc/network/interfaces" file:

allow-hotplug wlan1
iface wlan1 inet dhcp
        wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

By running the following commands you will be able to connect your board to a WiFi router:

$ ifdown wlan1
$ ifup wlan1

If your WiFi password has special characters or you don't want your password saved as plain text you can use "wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:

$ wpa_passphrase YourWiFiESSID

Following the prompt type in your password and you will get a new password in the /etc/wpa_supplicant/wpa_supplicant.conf file. Now you can replace the existing password in the wlan0 file with the new one.

6.10 Connect NanoPi M1 Plus to DVP Camera CAM500B

Note:this function is only supported in Linux-3.4.y
The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to Matrix - CAM500B.

Follow the hardware setup presented in the above picture to connect your NanoPi M1 Plus to a CAM500B. Then boot OS on your M1 Plus, connect your M1 Plus to a network, log into the board as root and run "mjpg-streamer":

$ cd /root/mjpg-streamer
$ make
$ ./start.sh

The mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:

 
 i: Using V4L2 device.: /dev/video0
 i: Desired Resolution: 1280 x 720
 i: Frames Per Second.: 30
 i: Format............: YUV
 i: JPEG Quality......: 90
 o: www-folder-path...: ./www/
 o: HTTP TCP port.....: 8080
 o: username:password.: disabled
 o: commands..........: enabled

In our case the M1 Plus' IP address was 192.168.1.230. We typed 192.168.1.230:8080 in a browser and were able to view the images taken from the camera's. Here is what you would expect to observe:

The mjpg-streamer soft-encodes data with libjpeg and you can hard-encode (note:this function is only supported in Linux-3.4.y) its data with ffmpeg which will greatly increase CPU's efficiency and speed up data encoding:

$ ffmpeg -t 30 -f v4l2 -channel 0 -video_size 1280x720 -i /dev/video0 -pix_fmt nv12 -r 30 \
        -b:v 64k -c:v cedrus264 test.mp4

By default it records a 30-second video. Typing "q" stops video recording. After recording is stopped a test.mp4 file will be generated.

6.11 Connect NanoPi M1 Plus to USB Camera(FA-CAM202)

The FA-CAM202 is a 200M USB camera.
In this use case the NanoPi M1 Plus runs Debian. Connect your NanoPi M1 Plus 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.

6.12 Use OpenCV to Access 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

Refer to the instructions in the previous sections to make sure the camera works
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:

6.13 Check CPU's Working Temperature

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

cpu_freq

6.14 Check System Information with Rpi-Monitor

Our Debian contains the Rpi-Monitor utility with which users can check system information and status.
In our case our NanoPi M1's IP was 192.168.1.230 and we typed the following IP in a browser:

192.168.1.230:8888

We were directed to the following page:

Users can easily check these system information and status.

7 Make Your Own Debian

7.1 Use Mainline BSP

The NanoPi M1 Plus has gotten support for kernel Linux-4.x.y with Ubuntu Core 16.04. For more details about how to use mainline u-boot and Linux-4.x.y refer to :Mainline U-boot & Linux

7.2 Use Allwinner's BSP

7.2.1 Preparations

Visit this link [1] and enter the "sources/nanopi-H3-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 ./
android lichee

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.

7.2.2 Install Cross Compiler

Visit this site download link, enter the "toolchain" directory, download the cross compiler "gcc-linaro-arm.tar.xz" and copy it to the "lichee/brandy/toochain/" directory.

7.2.3 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 run 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.

7.2.4 Package System Modules

./gen_script.sh -b nanopi-m1-plus

This command patches the uboot with Allwinner features and 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.

Run the following commands to update the uboot on your MicroSD card:

./fuse_uboot.sh /dev/sdx

Replace the "/dev/sdx" with the actual device name of your MicroSD card.
The boot.img and kernel modules are under the "linux-3.4/output" directory. You can copy the new boot.img file to your MicroSD card's boot section.

7.2.5 Compile U-boot

./build.sh -p sun8iw7p1 -b nanopi-h3 -m uboot
./gen_script.sh -b nanopi-m1-plus

The gen_script.sh script patches the U-boot with Allwinner features. A U-boot without these features cannot work.
Type the following command to update the U-boot on the MicroSD card:

./fuse_uboot.sh /dev/sdx

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

7.2.6 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 boot.img and its kernel modules will be generated under "linux-3.4/output".

7.2.7 Clean Source Code

./build.sh -p sun8iw7p1_linux -b nanopi-h3 -m clean
