====关于LCD/HDMI分辨率====
+
====Extend NanoPi M3's TF Card Section====
系统启动时uboot会自动识别LCD,成功则会设置为该LCD的显示分辨率,失败则缺省会设置为HDMI 720P模式。<br />
+
* When Debian/Ubuntu is loaded the TF card's section will be automatically extended.
如果要修改LCD的显示分辨率,可以直接修改内核中的文件 arch/arm/plat-s5p6818/nanopi3/lcds.c , 然后重新编译内核并更新即可。<br />
+
* When Android is loaded you need to run the following commands on your host PC to extend your TF card's section:
对于HDMI的显示模式,Android则是会通过EDID获得HDMI设备如电视机所支持的显示模式,然后自动选择一个合适的分辨率。如果使用的是Debian,则缺省是720P,可通过修改内核配置来切换为1080P。
+
<syntaxhighlight lang="bash">
 +
sudo umount /dev/sdx?
 +
sudo parted /dev/sdx unit % resizepart 4 100 resizepart 7 100 unit MB print
 +
sudo resize2fs -f /dev/sdx7
 +
</syntaxhighlight>
 +
(Note: you need to replace "/dev/sdx" with the device name in your system)
  
===在电脑上修改SD卡上的系统===
+
====LCD/HDMI Resolution====
如果你想在运行系统之前,先对系统做一些修改,可以参看本节内容,否则可以跳过本节。<br />
+
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.<br/>
将制作好SD卡插入一台运行Linux的电脑,可以挂载SD卡上的boot和rootfs等分区,对分区内容进行修改,通过在以下情况下你需要进行这些操作:<br />
+
If you want to modify the LCD resolution you can modify file "arch/arm/plat-s5p6818/nanopi3/lcds.c" in the kernel and recompile it.<br/>
1) 你想更改Kernel Command Line参数,则可以通过sd-fuse_nanopi3/tools目录下的fw_setenv工具来操作。<br />
+
If your NanoPi M3 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 M3 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.<br/>
查看当前的Command Line:
+
 
 +
===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.<br/>
 +
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:<br />
 +
1) If you want to change your kernel command line parameters you can do it via the fw_setevn utility under "sd-fuse_s5p6818/tools".<br/>
 +
Check the current Command Line<br/>
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
cd sd-fuse_nanopi3/tools
+
cd sd-fuse_s5p6818/tools
 
./fw_printenv /dev/sdc | grep bootargs
 
./fw_printenv /dev/sdc | grep bootargs
 
</syntaxhighlight>
 
</syntaxhighlight>
目前的Android 5.1.1_r6启用了SELinux,缺省模式是enforcing,你可以通过Command Line来修改它,例如:
+
Android 5.1.1_r6 starts SELinux. By default it is enforcing. You can change it this way:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive
 
./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive
 
</syntaxhighlight>
 
</syntaxhighlight>
即可修改为permissive模式,其中上面的XXX需要替换成原来的bootargs值。<br />
+
This sets it to "permissive". The "XXX" stands for the original bootargs' value.<br />
  
2) 更新内核 <br />
+
2) Update Kernel<br />
新版本的uboot在启动时如果识别到LCD,将读取SD卡boot分区的uImage,否则将读取uImage.hdmi。<br />
+
Our customized uboot will check the LCD type when it boots.<br/>
对于Android来说是同一个文件,因此直接使用新编译的uImage来替换SD卡boot分区下的文件即可。<br />
+
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".<br/>
对于Debian来说,这2个文件是不相同的,使用新编译的支持LCD的uImage直接替换SD卡boot分区的文件,如果是支持HDMI的内核,则替换uImage.hdmi。<br />
+
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.<br/>
  
===运行Android或Debian===
+
===Run Android or Debian===
*将制作好SD卡插入NanoPC M3,连接HDMI,按住靠近网口的boot按键,最后接电源(5V 2A)拨动开关,NanoPC M3会从SD卡启动。你可以看到板上PWR灯常亮,LED1灯闪烁,这说明系统已经开始启动了,同时电视上也将能看到系统启动的画面。<br />
+
* Insert a MicroSD card with Android/Debian image files into your NanoPi M3, connect the NanoPi M3 to an HDMI monitor and a 5V/2A power source the NanoPi M3 will be automatically powered up. If you can see the PWR LED is on and LED1 is flashing it means your board is working and you will see Android/Debain loading on the HDMI monitor.<br/>
1)要在电视上进行操作,你需要连接USB鼠标和键盘;如果你选购了LCD配件,则可以直接使用LCD上面的触摸屏进行操作。<br />
+
1) If you connect the NanoPi M3 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.<br/>
2)如果您需要进行内核开发,你最好选购一个串口配件,连接了串口,则可以通过终端对NanoPC M3进行操作。<br />
+
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.<br/>
*以下是串口的接法。接上串口,即可调试:
+
* Here is a setup where we connect a NanoPi M3 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal:

*如果提示输入密码,Debian的root用户的默认密码是两个字母fa。
+
* Under Debian the password for "root" is "fa".
  
===通过VNC和ssh登录Debian===
+
==Working with Debian==
如果你是祼板运行系统(既没有连接LCD也没有连接HDMI),并且烧写了带 -wifiap.img 后辍的固件,你可以使用手机,或者有无线网卡的电脑连接到NanoPC M3开放的 nanopi2-wifiap 无线热点(默认密码是123456789),连接成功后,无论是手机还是电脑,你可以到[http://www.realvnc.com/download/ 这里]下载并安装一个名为VNC Viewer的软件,用VNC连接到NanoPC M3,NanoPC M3在使用VNC时的连接地址和端口为:192.168.8.1:5901,默认密码为:fa123456,以下是在iPhone上用VNC登录NanoPC-T2的画面:<br />

===Ethernet Connection===
[[File:iphone6-vnc-nanopi2.png|frameless|400px|VNC to NanoPi2]]
+
* If the NanoPi M3 is connected to a network via Ethernet before it is powered on, it will automatically obtain an IP after it is powered up.
<br />
+
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。<br />
+
<br />
+
为了保证ssh的流畅,我们用以下命令关闭wifi的省电模式:
+
<syntaxhighlight lang="bash">
+
iwconfig wlan0 power off
+
</syntaxhighlight>
+
  
==Debian系统的使用==
+
===Wireless Connection===
===连接有线网络===
+
Open the file "/etc/wpa_supplicant/wpa_supplicant.conf" with vi or gedit and append the following lines:
* NanoPC M3支持千兆网络,Debian或者Android系统在启动前,只要接上网线,系统启动后则会自动分配IP地址,不需要额外去配置。
+
 
+
===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:
+
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
network={
 
network={
Line 294: Line 293:

}
 
</syntaxhighlight>
 
</syntaxhighlight>
其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。<br />
+
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.<br/>
保存退出后,执行以下命令即可连接WiFi: <br />
+
Save, exit and run the following commands your board will be connected to your specified WiFi.<br/>
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
ifdown wlan0
 
ifdown wlan0
Line 301: Line 300:
 
</syntaxhighlight>
 
</syntaxhighlight>
  
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: <br />
+
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:<br />
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
wpa_passphrase YourWiFiESSID
 
wpa_passphrase YourWiFiESSID
 
</syntaxhighlight>
 
</syntaxhighlight>
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。
+
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.
  
如果你的WiFi当前处于无线热点模式,你需要先退出该模式方可连接到路由器,使用以下命令退出无线热点模式:
+
If the system's WiFi AP mode is on it cannot search and connect to a wireless router. You need to turn off the WiFi AP mode by following the instructions below:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">

You can follow the steps below to setup WiFi AP:<br />
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
turn-wifi-into-apmode yes
 
turn-wifi-into-apmode yes
 
</syntaxhighlight>
 
</syntaxhighlight>
按提示重启即可,默认的热点名称为 nanopi2-wifiap,密码为123456789。<br />
+
Reboot the system as prompted. By default the AP's name is "nanopi2-wifiap" and the password is 123456789.<br/>
 
<br />
 
<br />
现在,你可以在电脑上搜索并连接nanopi2-wifiap这个无线热点,连接成功后,可以通过ssh到192.168.8.1这个地址来登录NanoPC M3:
+
Now you are able to find the "nanopi2-wifiap" from a host PC and connect to it. If a connection is successful you will be able to SSH to this NanoPi M3 at "192.168.8.1":
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
ssh root@192.168.8.1
 
ssh root@192.168.8.1
 
</syntaxhighlight>
 
</syntaxhighlight>
在提示输入密码时,输入预设的密码fa,即可登入。<br />
+
The password for it is "fa".<br />
 
<br />
 
<br />
为了保证ssh的流畅,我们用以下命令关闭wifi的省电模式:

From the above messages we could get the channel number 25 for the "OBEX Object Push" service. We input this number to the "ussp-push" by running the following command:
 +
<syntaxhighlight lang="bash">
 +
ussp-push 38:BC:1A:B1:7E:DD@25 example.jpg example.jpg
 +
</syntaxhighlight>
 +
Note: you need to use your device's name, its MAC address and channel number when you run these commands.<br /><br />
 +
Usually after the above commands are run a popup window will show on the phone that communicates with T2 and you can start file transfers.<br />
 +
<br />
 +
Common Issues:<br />
 +
1) If T2 cannot find a Bluetooth device you can try this command to restart its Bluetooth:<br />
 +
<syntaxhighlight lang="bash">
 +
rfkill unblock 0
 +
</syntaxhighlight>
 +
2) If any of these commands is not installed you can try this command to install it:<br />
 +
<syntaxhighlight lang="bash">
 +
apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push
 +
</syntaxhighlight>
  
===安装Debian软件包===
+
===Install Debian Packages===
我们提供的是标准的Debian jessie系统,你可以使用apt-get等命令来安装软件包,如果板子是首次运行,需要先用以下命令更新软件包列表:
+
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:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
apt-get update
 
apt-get update
 
</syntaxhighlight>
 
</syntaxhighlight>
然后就可以安装软件包了,例如要安装ftp服务器,使用以下命令:
+
You can install your preferred packages. For example if you want to install an FTP server you can do this:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
apt-get install vsftpd
 
apt-get install vsftpd
 
</syntaxhighlight>
 
</syntaxhighlight>
如果软件包下载速度不理想,你可以编辑 /etc/apt/sources.list 更换一个更快的源服务器,这个网址[http://www.debian.org/mirror/list]有一份完整的源镜像服务器列表,注意要选用一个带armhf架构的。
+
Note: you can change your download server by editting "/etc/apt/sources.list". You can get a complete server list from [http://www.debian.org/mirror/list]. You need to select the one with "armhf".
==如何编译系统==
+
 
 +
===Audio Output from HDMI or 3.5mm Jack under Debian===
 +
Our default Debian image for the NanoPi M3 doesn't support audio output. If you want to enable this function you need to install the alsa package.
 +
* Make sure your Debian OS is our latest version and your board has access to the internet;
 +
* Power up your board and run the following commands on your board's commandline utility to install the alsa package:
 +
<syntaxhighlight lang="bash">
 +
apt-get update
 +
apt-get install libasound2
 +
apt-get install alsa-base
 +
apt-get install alsa-utils
 +
</syntaxhighlight>
 +
* After the installation is done copy a ".wav" audio file to your NanoPi M3, connect your M3 to a earphone or speaker and try playing this audio file(By default Debian's audio output is from the 3.5mm audio jack):
 +
<syntaxhighlight lang="bash">
 +
aplay music.wav
 +
</syntaxhighlight>
 +
* By default Debian's audio output is from the 3.5mm audio jack. If you want audio output from the HDMI you need to change the setting by editing the "/etc/asound.conf" file:
 +
<syntaxhighlight lang="bash">
 +
pcm.!default {
 +
    type hw
 +
    card 1
 +
    device 0}
 +
 +
ctl.!default {
 +
    type hw
 +
    card 1}
 +
</syntaxhighlight>
 +
card 0 stands for the 3.5mm audio jack and card 1 stands for the HDMI audio. After you make your change reboot your board to make it effective.
 +
 
 +

====如何使用新编译的内核====
+
====User Your Generated Kernel====
* 更新SD卡上的内核
+
* Update the kernel file in SD card
如果您是使用SD卡启动Android,则在PC上复制为Android编译的uImage到SD卡的boot分区(即分区1,设备是/dev/sdX1)即可。<br />
+
If you use an SD card to boot Android you can copy your generated uImage file to your SD card's boot partition(e.g. section 1 /dev/sdX1).<br/>
如果您是使用SD卡启动Debian系统,则需要编译好用于HDMI的uImage后替换SD卡boot分区下的uImage.hdmi,然后编译用于LCD的uImage并替换SD卡boot分区下的uImage。
+
If you use an SD card to Debian and you generated a uImage for an HDMI monitor you can use that uImage to replace the uImage.hdmi file in the SD card's boot partition. If you use an SD card to Debian and you generated a uImage for an LCD you can use that uImage to replace the uImage file in the SD card's boot partition.
  
* 更新eMMC上Android的内核
+
====Compile Kernel Modules====
如果只想单独更新eMMC上的内核来测试,则需要先正常启动板,然后mount eMMC的boot分区,使用新编译的uImage来替换原有文件,完成后reboot即可。<br />
+
Android contains kernel modules which are in the "/lib/modules" directory in the system section. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.<br/>
从eMMC启动时可通过以下方法来更新内核:<br />
+
Compile Original Kernel Modules:
1) 启动完成后,需要手动mount eMMC的boot分区(设备是/dev/mmcblk0p1), 可通过串口在板上操作:<br />
+
<syntaxhighlight lang="bash">
+
su
+
mount -t ext4 /dev/block/mmcblk0p1 /mnt/media_rw/sdcard1/
+
</syntaxhighlight>
+
2) 连接USB,在PC端Ubuntu下使用adb push命令复制新编译的uImage到已mount的boot分区下; <br />
+
<syntaxhighlight lang="bash">
+
adb push uImage /mnt/media_rw/sdcard1/
+
</syntaxhighlight>
+
3) 也可以将编译好的内核复制到SD卡或U盘,然后在板上复制到boot分区下; <br />
+
4) 更新完成后,输入 reboot 命令重启即可,注意不要直接断电或按Reset键,否则可能会损坏文件。 <br />
+
 
+
* 更新eMMC上Debian的内核
+
从eMMC启动时可通过以下方法来更新内核:<br />
+
1) 启动完成后,系统通常会自动mount eMMC的boot分区(设备是/dev/mmcblk0p1), 可输入命令mount来查看; <br />
+
2) 连接网络,使用scp/ftp等方式复制新编译的uImage并替换boot分区下的文件,如果是用于HDMI的内核,则替换uImage.hdmi; <br />
+
3) 也可以将编译好的内核复制到SD卡或U盘,然后在板止复制到boot分区下; <br />
+
4) 更新完成后,输入 reboot 命令重启即可,注意不要直接断电或按Reset键,否则可能会损坏文件. <br />
+
 
+
* 使用新的内核来生成boot.img
+
如果要生成直接烧写eMMC的文件,则需要使用新编译的内核来生成boot.img,然后复制到烧写用的SD卡即可直接烧写到eMMC. <br />
+
对于Android,将新的uImage复制Android源码的device/friendly-arm/nanopi3/boot/ 下,然后编译Android即可获得新的boot.img . <br />
+
对于Debian, 则需要使用按以下方法来生成boot.img : <br />
+
1) 下载debian_nanopi2
+
<syntaxhighlight lang="bash">
+
git clone https://github.com/friendlyarm/debian_nanopi2.git
+
</syntaxhighlight>
+
2) 复制用于HDMI的uImage到debian_nanopi2/boot/uImage.hdmi, 复制用于LCD的 uImage到debian_nanopi2/boot/uImage ; <br />
+
3) 生成Debian的 boot.img
+
<syntaxhighlight lang="bash">
+
cd debian_nanopi2
+
mkdir rootfs
+
./build.sh
+
</syntaxhighlight>
+
新的 boot.img 在 debian_nanopi2/sd-fuse_nanopi2/debian 下. <br />
+
其中命令"mkdir rootfs"只是创建一个空的目录使得build.sh可以运行,因此生成的其它文件比如rootfs.img不能使用。
+
 
+
====编译内核模块====
+
Android包含内核模块,位于system分区的 /lib/modules/ 下,如果您有新的内核模块或者内核配置有变化,则需要重新编译。 <br />
+
首先编译内核源代码中的模块:
+
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
cd linux-3.4.y
 
cd linux-3.4.y
 
make CROSS_COMPILE=arm-linux- modules
 
make CROSS_COMPILE=arm-linux- modules
 
</syntaxhighlight>
 
</syntaxhighlight>
另外有2个内核模块的源代码位于Android源代码中,可使用以下命令来编译:
+
Here we have two new modules and we can compile them by following the commands below:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
 
cd /opt/FriendlyARM/s5p6818/android
 
cd /opt/FriendlyARM/s5p6818/android
 
./vendor/friendly-arm/build/common/build-modules.sh
 
./vendor/friendly-arm/build/common/build-modules.sh
 
</syntaxhighlight>
 
</syntaxhighlight>
其中 “/opt/FriendlyARM/s5p6818/android” 是指Android源代码的TOP目录,使用参数“-h”可查看帮助。<br />
+
The "/opt/FriendlyARM/s5p6818/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".<br/>
编译成功结束后,会显示生成的内核模块。
+
After your compilation succeeds new modules will be generated.

* 烧写到eMMC
+
==Connect NanoPi M3 to External Modules==
成功编译Android后,可过2种方式烧写到eMMC,分别如下:<br />
+
===Connect NanoPi M3 to USB Camera(FA-CAM202)===
1) fastboot: 板子从eMMC启动后通过串口快速按任意键进入uboot命令行模式,输入命令fastboot即可启动此方式。<br />
+
* In this use case the NanoPi M3 runs Debian. If you connect your NanoPi M3 to our LCD or an HDMI monitor after Debain is fully loaded click on "other"-->"xawtv" on the left bottom of the GUI and the USB Camera application will be started. After enter "welcome to xawtv!" click on "OK" to start exploring.
连接USB线,然后PC端输入以下命令:
+
[[File:USB-camera-nanopiM3-Fire.png|frameless|500px|USB camera-Fire]]
 +
 
 +
===Connect NanoPi M3 to CMOS 5M-Pixel Camera===
 +
Check this link [http://wiki.friendlyelec.com/wiki/index.php/Matrix_-_CAM500B] for details about the camera CAM500B we tested in this case<br/>
 +
* In this use case the NanoPi M3 runs Android5.1. If you connect your NanoPi M3 to our LCD or an HDMI monitor after Android is fully loaded click on the "Camera" icon and the application will be started.
 +
[[File:CMOS-camera-nanopiM3.png|frameless|500px|CMOS camera-M3]]
 +
 
 +
*There is a camera utility "nanocams" in Debian/Ubuntu. You can preview and save 40 frames to an image file by running the following command
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
cd out/target/product/nanopi3
+
sudo nanocams -p 1 -n 40 -c 4 -o IMG001.jpg
sudo fastboot flash boot boot.img
+
sudo fastboot flash cache cache.img
+
sudo fastboot flash userdata userdata.img
+
sudo fastboot flash system system.img
+
sudo fastboot reboot
+
 
</syntaxhighlight>
 
</syntaxhighlight>
2) 使用SD卡烧写 <br />
+
For more details about the usage of the utility you can command "nanocams -h".
复制out/target/product/nanopi3下的boot.img, cache.img, userdata.img, system.img, partmap.txt到烧写用SD卡的images/android下,再次烧写即可。<br />
+
If you want to download the source code you can get it from our github:
 +
<syntaxhighlight lang="bash">
 +
git clone https://github.com/friendlyarm/nexell_linux_platform.git
 +
</syntaxhighlight>
 +
 
 +
===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.
 +
* When the NanoPi M3 runs Debian users can use OpenCV APIs to access a USB Camera device.<br>
 +
1. Here is a guideline on how to use OpenCV with C++ on the NanoPi M3:
 +
* Firstly you need to make sure your NanoPi M3 is connected to the internet.Login to your NanoPi M3 via a serial terminal or SSH. After login type in your username(root) and password(fa):
 +
* Run the following commands:
 +
<br>
 +
<syntaxhighlight lang="bash">
 +
apt-get update
 +
apt-get install libcv-dev libopencv-dev
 +
</syntaxhighlight>
 +
 
 +
2. Make sure your USB camera works with the NanoPi M3. You can test your camera with NanoPi M3's camera utility.<br>
 +
 
 +
3. Check your camera device:
 +
<syntaxhighlight lang="bash">
 +
ls /dev/video*
 +
</syntaxhighlight>
 +
* Note:in our test case video0 was the device name.
 +
 
 +
4. OpenCV's code sample(official code in C++) is under /home/fa/Documents/opencv-demo. Compile the code sample with the following commands:
 +
<syntaxhighlight lang="bash">
 +
cd /home/fa/Documents/opencv-demo
 +
make
 +
</syntaxhighlight>
 +
After it is compiled successfully a "demo" executable will be generated<br />
 +
 
 +
5. Connect NanoPi M3 to USB Keyboard & Run the Following Command:
 +
<syntaxhighlight lang="bash">
 +
./demo
 +
</syntaxhighlight>
 +
opencv is successfully started<br>
 +

4 Get Started

4.1 Essentials You Need

Before starting to use your NanoPi M3 get the following items ready

  • NanoPi M3
  • 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, mouse and possible a USB hub(or a TTL to serial board)
  • A host computer running Ubuntu 18.04 64 bit system

4.2 TF Cards We Tested

chuanyu microSD 8G

4.3 Make an Installation SD Card

4.3.1 Boot NanoPi M3 from SD Card

Get the following files from the download link to download necessary files:

  • Get a 4G SDHC card and backup its data if necessary.
Image Files:
s5p6818-debian-sd4g-20160426.img Debian image files
s5p6818-android-sd4g-20160426.img Android image files
s5p6818-ubuntu-core-qte-sd4g-20160426.img Ubuntu Core + QT 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 M3's boot slot, press and hold the boot key and power on (with a 5V/3A power source). If the green LED is on and the blue LED is blinking this indicates your NanoPi M3 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_s5p6818.git
cd sd-fuse_s5p6818
  • 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 M3'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-s5p6818/nanopi3/lcds.c" in the kernel and recompile it.
If your NanoPi M3 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 M3 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_s5p6818/tools".
Check the current Command Line

cd sd-fuse_s5p6818/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 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 M3, connect the NanoPi M3 to an HDMI monitor and a 5V/2A power source the NanoPi M3 will be automatically powered up. If you can see the PWR LED is on and LED1 is flashing it means your board is working and you will see Android/Debain loading on the HDMI monitor.

1) If you connect the NanoPi M3 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 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 M3 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal:

PSU-ONECOM02-M3

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

5 Working with Debian

5.1 Ethernet Connection

  • If the NanoPi M3 is connected to a network via Ethernet before it is powered on, it will automatically obtain an IP after it is powered up.

5.2 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.

If the system's WiFi AP mode is on it cannot search and connect to a wireless router. You need to turn off the WiFi AP mode by following the instructions below:

su
turn-wifi-into-apmode no

5.3 Setup Wi-Fi AP

You can follow the steps below to setup WiFi AP:

turn-wifi-into-apmode yes

Reboot the system as prompted. By default the AP's name is "nanopi2-wifiap" and the password is 123456789.

Now you are able to find the "nanopi2-wifiap" from a host PC and connect to it. If a connection is successful you will be able to SSH to this NanoPi M3 at "192.168.8.1":

ssh root@192.168.8.1

The password for it is "fa".

To make SSH session run faster turn off the WiFi's power saving mode by using the following command:

iwconfig wlan0 power off

You can check the WiFi mode via the following command:

cat /sys/module/bcmdhd/parameters/op_mode

If the result is "2" it means it is currently working as a WiFi AP.If you want to switch back to the Station mode you can do it this way:

turn-wifi-into-apmode no

5.4 Bluetooth

Here are the steps to transfer a file from T2 to a mobile phone. Run the following command to search a surrounding Bluetooth device:

hcitool scan


In our example a mobile phone was detected and the following messages were listed:
Scanning ...
38:BC:1A:B1:7E:DD MEIZU MX4

These messages indicated that a MEIZU MX4 mobile phone was detected. We then checked the Bluetooth services this phone supported with its MAC address presented in front of its device name

sdptool browse 38:BC:1A:B1:7E:DD

Note: you need to use your device's name and its MAC address when you run these commands.

The command listed all the services the phone supported. We needed the "OBEX Object Push" service which is for file transfers.
Service Name: OBEX Object Push
Service RecHandle: 0x1000b
Service Class ID List:
"OBEX Object Push" (0x1105)
Protocol Descriptor List:
"L2CAP" (0x0100)
"RFCOMM" (0x0003)
Channel: 25
"OBEX" (0x0008)
Profile Descriptor List:
"OBEX Object Push" (0x1105)
Version: 0x0100

From the above messages we could get the channel number 25 for the "OBEX Object Push" service. We input this number to the "ussp-push" by running the following command:

ussp-push 38:BC:1A:B1:7E:DD@25 example.jpg example.jpg

Note: you need to use your device's name, its MAC address and channel number when you run these commands.

Usually after the above commands are run a popup window will show on the phone that communicates with T2 and you can start file transfers.

Common Issues:
1) If T2 cannot find a Bluetooth device you can try this command to restart its Bluetooth:

rfkill unblock 0

2) If any of these commands is not installed you can try this command to install it:

apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push

5.5 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".

5.6 Audio Output from HDMI or 3.5mm Jack under Debian

Our default Debian image for the NanoPi M3 doesn't support audio output. If you want to enable this function you need to install the alsa package.

  •  Make sure your Debian OS is our latest version and your board has access to the internet;
  •  Power up your board and run the following commands on your board's commandline utility to install the alsa package:
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 M3, connect your M3 to a earphone or speaker and try playing this audio file(By default Debian's audio output is from the 3.5mm audio jack):
aplay music.wav
  • By default Debian's audio output is from the 3.5mm audio jack. If you want audio output from the HDMI you need to change the setting by editing the "/etc/asound.conf" file:
pcm.!default {
    type hw
    card 1
    device 0}
 
ctl.!default {
    type hw
    card 1}

card 0 stands for the 3.5mm audio jack and card 1 stands for the HDMI audio. After you make your change reboot your board to make it effective.

6 Make Your Own OS Image

6.1 Install Cross Compiler

Download the compiler package:

git clone https://github.com/friendlyarm/prebuilts.git -b master --depth 1
cd prebuilts/gcc-x64
cat toolchain-4.9.3-armhf.tar.gz* | sudo tar xz -C /

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 take 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 machine. 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
Target: arm-cortexa9-linux-gnueabihf
Configured with: /work/toolchain/build/src/gcc-4.9.3/configure --build=x86_64-build_pc-linux-gnu
--host=x86_64-build_pc-linux-gnu --target=arm-cortexa9-linux-gnueabihf --prefix=/opt/FriendlyARM/toolchain/4.9.3
--with-sysroot=/opt/FriendlyARM/toolchain/4.9.3/arm-cortexa9-linux-gnueabihf/sys-root --enable-languages=c,c++
--with-arch=armv7-a --with-tune=cortex-a9 --with-fpu=vfpv3 --with-float=hard
...
Thread model: posix
gcc version 4.9.3 (ctng-1.21.0-229g-FA)

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 s5p6818_nanopi3_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 SD card via fastboot. Here is how you can do it:
1) On your host PC run "sudo apt-get install android-tools-fastboot" to install the fastboot utility;
2) Connect your NanoPi M3 to your host PC via a serial cable (e.g. PSU-ONECOME). Press the enter key within two seconds right after you power on your NanoPi M3 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 M3 to this host PC via a microUSB cable and type in the following command to flash u-boot.bin;

fastboot flash bootloader u-boot.bin


Warning: you cannot update this SD card by commanding "dd". This command will cause trouble when booting the NanoPi M3.

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

6.4 Compile Linux Kernel

6.4.1 Compile Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux-3.4.y.git
cd linux-3.4.y
git checkout nanopi2-lollipop-mr1

The NanoPi M3's kernel source code lies in the "nanopi2-lollipop-mr1" branch

  • Compile Android Kernel
make nanopi3_android_defconfig
touch .scmversion
make uImage
  • Compile Debian Kernel
make nanopi3_linux_defconfig
touch .scmversion
make uImage

After your compilation succeeds a uImage will be generated in the "arch/arm/boot/uImage" directory. This kernel is for HDMI 720P. You can use it to replace the existing uImage.hdmi.
If you want to generate a kernel for HDMI 1080P you can do it this way:

touch .scmversion
make nanopi3_linux_defconfig
make menuconfig
  Device Drivers -->
    Graphics support -->
      Nexell Graphics -->
        [ ] LCD
        [*] HDMI
        (0)   Display In  [0=Display 0, 1=Display 1]
              Resolution (1920 * 1080p)  --->
make uImage

After your compilation succeeds a uImage will be generated for HDMI 1080P. You can use it to replace the existing uImage.

6.4.2 User Your Generated Kernel

  • Update the kernel file in SD card

If you use an SD card to boot Android you can copy your generated uImage file to your SD card's boot partition(e.g. section 1 /dev/sdX1).
If you use an SD card to Debian and you generated a uImage for an HDMI monitor you can use that uImage to replace the uImage.hdmi file in the SD card's boot partition. If you use an SD card to Debian and you generated a uImage for an LCD you can use that uImage to replace the uImage file in the SD card's boot partition.

6.4.3 Compile Kernel Modules

Android contains kernel modules which are in the "/lib/modules" directory in the system section. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.
Compile Original Kernel Modules:

cd linux-3.4.y
make CROSS_COMPILE=arm-linux- modules

Here we have two new modules and we can compile them by following the commands below:

cd /opt/FriendlyARM/s5p6818/android
./vendor/friendly-arm/build/common/build-modules.sh

The "/opt/FriendlyARM/s5p6818/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".
After your compilation succeeds new modules will be generated.

6.5 Compile Android

  • Install Cross Compiler

Install 64 bit Ubuntu 16.04 on your host PC.

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex libncurses5-dev zlib1g-dev gawk minicom

For more details refer to https://source.android.com/source/initializing.html

  • Download Source Code

You need to use repo to get the Android source code. Refer to https://source.android.com/source/downloading.html

mkdir android && cd android
repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi3-lollipop-mr1
repo sync

The "android" directory is the working directory.

  • Compile System Package
source build/envsetup.sh
lunch aosp_nanopi3-userdebug
make -j8

After your compilation succeeds an image will be generated in the "out/target/product/nanopi3/" directory.

filename partition Description
boot.img boot -
cache.img cache -
userdata.img userdata -
system.img system -
partmap.txt - partition file
  • Flash Image to SD Card

If you want to boot your board from an SD card you need to copy your generated image file to the "sd-fuse_s5p6818/android/" directory and flash it to your SD card with our script. For more details refer to #Under Linux Desktop.

7 Connect NanoPi M3 to External Modules

7.1 Connect NanoPi M3 to USB Camera(FA-CAM202)

  • In this use case the NanoPi M3 runs Debian. If you connect your NanoPi M3 to our LCD or an HDMI monitor after Debain is fully loaded click on "other"-->"xawtv" on the left bottom of the GUI and the USB Camera application will be started. After enter "welcome to xawtv!" click on "OK" to start exploring.

USB camera-Fire

7.2 Connect NanoPi M3 to CMOS 5M-Pixel Camera

Check this link [2] for details about the camera CAM500B we tested in this case

  • In this use case the NanoPi M3 runs Android5.1. If you connect your NanoPi M3 to our LCD or an HDMI monitor after Android is fully loaded click on the "Camera" icon and the application will be started.

CMOS camera-M3

  • There is a camera utility "nanocams" in Debian/Ubuntu. You can preview and save 40 frames to an image file by running the following command
sudo nanocams -p 1 -n 40 -c 4 -o IMG001.jpg

For more details about the usage of the utility you can command "nanocams -h". If you want to download the source code you can get it from our github:

git clone https://github.com/friendlyarm/nexell_linux_platform.git

7.3 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.
  • When the NanoPi M3 runs Debian users can use OpenCV APIs to access a USB Camera device.

1. Here is a guideline on how to use OpenCV with C++ on the NanoPi M3:

  • Firstly you need to make sure your NanoPi M3 is connected to the internet.Login to your NanoPi M3 via a serial terminal or SSH. After login type in your username(root) and password(fa):
  • Run the following commands:


apt-get update
apt-get install libcv-dev libopencv-dev

2. Make sure your USB camera works with the NanoPi M3. You can test your camera with NanoPi M3's camera utility.

3. Check your camera device:

ls /dev/video*
  • Note:in our test case video0 was the device name.

4. OpenCV's code sample(official code in C++) is under /home/fa/Documents/opencv-demo. Compile the code sample with the following commands:

cd /home/fa/Documents/opencv-demo
make

After it is compiled successfully a "demo" executable will be generated

5. Connect NanoPi M3 to USB Keyboard & Run the Following Command:

./demo

opencv is successfully started
OpenCV-M3
