4.3 Make an Installation TF Card

4.3.1 Download Image Files

Get the following files from here download link to download image files (under the "officail-ROMs" diirectory) and the flashing utility (under the "tools" diirectory):

Image Files
nanopi-m1-plus-debian-sd4g.img.zip Debian Image File
nanopi-m1-plus-ubuntu-core-qte-sd4g.img.zip Ubuntu core with Qt Embedded
nanopi-m1-eflasher-sd8g.img.zip eflasher which can be used to Flash image files to eMMC
nanopi-m1-plus-android.img.zip Android Image File
Flash Utility
win32diskimager.rar Windows utility. 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 TF Card Systems

4.3.2.1 Make Debian Image Card
  • Extract the nanopi-m1-plus-debian-sd4g.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.

Note:you can make a Ubuntu image card in this way too.

4.3.2.2 Make Android Image 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 nanopi-m1-plus-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 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.

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

4.3.3 Flash image to eMMC with eflasher

  • Extract the nanopi-m1-eflasher-sd8g.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.

eflasher
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.

5 Work with Debian

5.1 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:

PSU-ONECOM-NanoPI-M1-Plus

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

5.2 Extend TF Card's rootfs Section

When you boot Debian 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

5.3 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

  • Setup MAC Address

The NanoPi M1 Plus by default doesn't have a valid MAC address. If the board connects a network successfully it will automatically generate 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 连接无线网络

用vi或在图形界面下用gedit编辑文件 /etc/wpa_supplicant/wpa_supplicant.conf, 在文件末尾填入路由器信息如下所示： 

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

其中，YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。
保存退出后，执行以下命令即可连接WiFi: 

ifdown wlan0
ifup wlan0

如果你的WiFi密码中有特殊字符，或者你不希望明文存放密码，你可以使用wpa_passphrase命令为WiFi密码生成一个密钥(psk)，用密钥来代替密码 ，在命令行下，可输入以下命令生成密钥: 

wpa_passphrase YourWiFiESSID

在提示输入密码时，输入你的WiFi密码，再打开 /etc/wpa_supplicant/wpa_supplicant.conf 文件你会发现密钥已经被更新，你可以删除明文的密码了。

5.5 通过VNC和ssh登录Debian

如果你不想连接HDMI，可以使用手机或电脑到这里下载并安装一个名为VNC Viewer的软件，用VNC连接到M1+，默认的端口号为1，密码为：fa123456 。
以下是在iPhone上用VNC登录M1+的画面：
VNC to NanoPi2
你也可以通过 ssh -l root 192.168.8.1 命令在终端上登录，默认的root用户密码是 fa 。请将192.168.8.1替换为实际IP地址。

5.6 HDMI输出声音

Debian系统默认从3.5mm耳机座输出声音，想从HDMI输出需要修改文件系统上的配置文件/etc/asound.conf如下： 

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

card 0代表3.5mm耳机孔，card 1代表HDMI音频。设置完成后需要重启系统才能生效。

5.7 测试GPU

启动Debian系统，在HDMI界面下登录Debian，打开终端并运行命令： 

glmark2-es2

测试效果如下：
m1-gpu-glmark2

5.8 测试VPU

访问此处下载地址的test-video目录下载视频文件，启动Debian系统，在HDMI界面下登录Debian，打开终端并运行命令： 

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

经测试，可流畅硬解播放1080p视频。

5.9 连接USB WiFi

Debian系统已经支持市面上众多常见的USB WiFi，想知道你的USB WiFi是否可用只需将其接在M1+上即可，已测试过的USB WiFi型号如下：

序号 型号
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 小米WiFi mt7601

M1+ 上电启动连接上USB WiFi后，通过串口登录到系统，敲入以下命令可以查看到系统是否识别到USB WiFi，如果出现“wlan0”，则证明USB WiFi已被识别到： 

ifconfig -a

用vi或在图形界面下用gedit编辑文件 /etc/wpa_supplicant/wpa_supplicant.conf, 在文件末尾填入路由器信息如下所示： 

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

其中，YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。
保存退出后，执行以下命令即可连接WiFi: 

ifdown wlan0
ifup wlan0

如果你的WiFi密码中有特殊字符，或者你不希望明文存放密码，你可以使用wpa_passphrase命令为WiFi密码生成一个密钥(psk)，用密钥来代替密码 ，在命令行下，可输入以下命令生成密钥: 

wpa_passphrase YourWiFiESSID

在提示输入密码时，输入你的WiFi密码，再打开 /etc/wpa_supplicant/wpa_supplicant.conf 文件你会发现密钥已经被更新，你可以删除明文的密码了。

5.10 连接DVP摄像头模块(CAM500B)

CAM500B是一款500万像素摄像头模块，以DVP并行信号输出，详细信息请参考Matirx-CAM500B。
NanoPi-M1-Plus-cam500a
根据上图连接M1+和CAM500B，然后上电启动Debian系统，连接网络，以root用户登录终端并编译运行mjpg-streamer: 

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

mjpg-streamer是一个开源的网络视频流服务器，在板子上成功运行mjpg-streamer后会打印下列信息:

 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

假设M1+的IP地址为192.168.1.230，在PC的浏览器中输入 192.168.1.230:8080 就能浏览摄像头采集的画面了，效果如下:
mjpg-streamer-cam500a
mjpg-streamer是用libjpeg对摄像头数据进行软编码，你可以使用ffmpeg对摄像头数据进行硬编码，这样能大大降低CPU的占用率并提高编码速度: 

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

默认会录制30秒的视频，输入q能终止录制。录制完成后会在当前目录生成一个名为test.mp4的视频文件，可将其拷贝到PC上进行播放验证。

5.11 连接USB摄像头模块(FA-CAM202)

FA-CAM202是一款200万像素的USB摄像头模块。
启动Debian系统，在HDMI界面下登录Debian，打开终端并运行命令： 

xawtv 0

可以在HDMI界面下正常看到摄像头的预览内容。 注：这里的"0"指的是接进板子的摄像头为/dev/video0设备，请根据实际情况填写video索引号。

5.12 连接摄像头测试OpenCV

OpenCV的全称是Open Source Computer Vision Library，是一个跨平台的计算机视觉库。
执行以下步骤测试OpenCV：

6 如何编译Debian系统

6.1 准备工作

访问此处下载地址的sources/nanopi-h3-bsp目录，下载所有压缩文件，使用7-Zip工具解压后得到lichee目录和android目录，请务必保证这2个目录位于同一个目录中，如下： 

ls ./
android lichee

也可以从github上克隆lichee源码： 

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

注：lichee是全志为其CPU的板级支持包所起的项目名称，里面包含了U-boot，Linux等源码和众多的编译脚本。

6.2 安装交叉编译器

访问此处下载地址的toolchain目录，下载交叉编译器gcc-linaro-arm.tar.xz，将该压缩包放置在lichee/brandy/toochain/目录下即可，无需解压。

6.3 编译lichee源码

编译全志 H3 的BSP源码包必须使用64bit的Linux PC系统，并安装下列软件包，下列操作均基于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

为Debian系统编译lichee源码包，进入lichee目录，执行命令： 

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

该命令会为Debian系统一次性编译好U-boot、Linux内核和模块。
lichee目录里内置了交叉编译器，当使用build.sh脚本进行源码编译时，会自动使用该内置的编译器，所以无需手动安装编译器。

6.4 打包系统组件

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

该命令会为U-boot打上全志系列CPU的硬件板级配置补丁，然后所有编译生成的可执行文件(包括U-boot、Linux内核)拷贝到lichee/tools/pack/out/目录以便进行统一管理。

下列命令可以更新TF卡上的U-boot： 

./fuse_uboot.sh /dev/sdx

/dev/sdx请替换为实际的TF卡设备文件名。
内核boot.img和驱动模块均位于linux-3.4/output目录下，将boot.img拷贝到TF卡的boot分区的根目录即可更新内核。

6.5 编译U-boot

如果你想单独编译U-boot，可以执行命令： 

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

gen_script.sh脚本会为U-boot打上全志系列CPU的硬件板级配置补丁，只有打过补丁文件的U-boot才能烧写到TF卡中正常运行。 执行下列命令更新TF卡上的U-boot： 

./fuse_uboot.sh /dev/sdx

/dev/sdx请替换为实际的TF卡设备文件名。

6.6 编译Linux内核

如果你想单独编译Linux内核，可以执行命令： 

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

编译完成后内核boot.img和驱动模块均位于linux-3.4/output目录下，将boot.img拷贝到TF卡的boot分区的根目录即可。
