+
 
+
*将固件和烧写工具分别解压,在Windows下插入SD卡(限4G及以上的卡),以管理员身份运行 win32diskimager 工具, 在win32diskimager工具的界面上, 选择你的SD卡盘符,选择你要烧写的系统固件,点击 Write 按钮烧写即可。
+
*当制作完成 SD 卡后,拔出 SD 卡插入 NanoPi M2A 的 BOOT 卡槽,上电启动(注意,这里需要 5V/3A 的供电),你可以看到红灯常亮以及蓝灯闪烁,这时你已经成功启动 NanoPi M2A。<br />
+
 
+
====在Linux Desktop下通过脚本制作====
+
* 1) 将microSD插入Ubuntu的电脑,用以下命令查看你的SD卡设备名
+
<syntaxhighlight lang="bash">
+
dmesg | tail
+
</syntaxhighlight>
+
当dmesg输出类拟信息 sdc: sdc1 sdc2时,则表示SD卡对应的设备名为 /dev/sdc,也通过用命令cat /proc/partitions来查看。
+
 
+
*2) 下载Linux下的制作脚本
+
<syntaxhighlight lang="bash">
+
git clone https://github.com/friendlyarm/sd-fuse_nanopi2.git
+
cd sd-fuse_nanopi2
+
</syntaxhighlight>
+
 
+
*3) 以下是制作启动Android的SD卡的方法
+
<syntaxhighlight lang="bash">
+
su
+
./fusing.sh /dev/sdx
+
</syntaxhighlight>
+
(注:/dev/sdx请替换为实际的SD卡设备文件名) <br />
+
制作包中未包含Android和Debian的烧写文件,第一次使用时会提示需要下载,输入Y下载,N或10秒未输入则取消。
+
 
+
*4) 以下是制作启动Debian的SD卡的方法
+
<syntaxhighlight lang="bash">
+
./fusing.sh /dev/sdx debian
+
</syntaxhighlight>
+
 
+
====NanoPi M2A 扩展TF卡分区====
+
* Debian/Ubuntu系统在启动的时候,会自动扩展SD卡分区,第一次开机时自动扩展分区和根文件系统。
+
* Android扩展分区,要在pc上执行下列操作:
+
<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>
+
(注:/dev/sdx请替换为实际的SD卡设备文件名)
+
 
+
====关于LCD/HDMI分辨率====
+
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 />
+
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-s5p4418/nanopi2/lcds.c , 然后重新编译内核并更新即可。<br />
+
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。
+
 
+
===在电脑上修改SD卡上的系统===
+
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 />
+
将制作好microSD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 />
+
1) 你想更改Kernel Command Line参数,则可以通过sd-fuse_nanopi2/tools目录下的fw_setenv工具来操作。<br />
+
查看当前的Command Line:
+
<syntaxhighlight lang="bash">
+
cd sd-fuse_nanopi2/tools
+
./fw_printenv /dev/sdc | grep bootargs
+
</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:
+
<syntaxhighlight lang="bash">
+
./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive
+
</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 />
+
 
+
2) 更新内核 <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 />
+
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 />
+
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 />
+
 
+
===运行Android或Debian===
+
* 将制作好SD卡插入NanoPi M2A,连接HDMI,最后接电源(5V 3A),NanoPi M2A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 />
+
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 />
+
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NanoPi M2A进行操作。<br />
+
*以下是串口的接法。接上串口,即可调试:
+
[[File:PSU-ONECOM02-M3.png|frameless|400px|PSU-ONECOM02-M3]]
+
* 如果提示输入密码,Debian的root用户的默认密码是两个字母fa。
+
 
+
===通过VNC和ssh登录Debian===
+
如果你是祼板运行系统(既没有连接LCD也没有连接HDMI),你可以使用手机或电脑到[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NanoPi M2A,默认密码为:fa123456 。<br />
+
以下是在iPhone上用VNC登录NanoPi M2A的画面:<br />
+
[[File:iphone6-vnc-nanopi2.png|frameless|400px|VNC to NanoPi2]]
+
<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 />
+
 
+
==Debian系统的使用==
+
===连接有线网络===
+
* NanoPi M2A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">
+
network={
+
        ssid="YourWiFiESSID"
+
        psk="YourWiFiPassword"
+
}
+
</syntaxhighlight>
+
其中,YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。<br />
+
保存退出后,执行以下命令即可连接WiFi: <br />
+
<syntaxhighlight lang="bash">
+
ifdown wlan0
+
ifup wlan0
+
</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 />
+
<syntaxhighlight lang="bash">
+
wpa_passphrase YourWiFiESSID
+
</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。
+
 
+
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:
+
<syntaxhighlight lang="bash">
+
su
+
turn-wifi-into-apmode no
+
</syntaxhighlight>
+
 
+
===配置Wi-Fi无线热点===
+
可以通过以下命令,将Wi-Fi切换至无线热点模式:<br />
+
<syntaxhighlight lang="bash">
+
turn-wifi-into-apmode yes
+
</syntaxhighlight>
+
按提示重启即可,默认的热点名称为 nanopi2-wifiap,密码为123456789。<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NanoPi M2A:
+
<syntaxhighlight lang="bash">
+
ssh root@192.168.8.1
+
</syntaxhighlight>
+
在提示输入密码时,输入预设的密码fa,即可登入。<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>
+
WiFi工作模式可通过以下命令查询:<br />
+
<syntaxhighlight lang="bash">
+
cat /sys/module/bcmdhd/parameters/op_mode
+
</syntaxhighlight>
+
输出为数字2则表示当前处于无线热点模式,要切换回普通的Station模式,输入如下命令:<br />
+
<syntaxhighlight lang="bash">
+
turn-wifi-into-apmode no
+
</syntaxhighlight>
+
 
+
===使用蓝牙传输文件===
+
以传输文件到手机为例进行说明,首先,将你的手机蓝牙设置为可侦测状态,然后执行以下命令开始蓝牙搜索:<br />
+
<syntaxhighlight lang="bash">
+
hcitool scan
+
</syntaxhighlight>
+
<br />
+
搜索到设备时,结果举例如下:<br />
+
Scanning ...<br />
+
38:BC:1A:B1:7E:DD      MEIZU MX4<br />
+
<br />
+
这表示搜索到一台名为MEIZU MX4的手机,我们记下手机名称前面的MAC地址,然后用sdptool命令查看该手机支持的蓝牙服务:<br />
+
<syntaxhighlight lang="bash">
+
sdptool browse 38:BC:1A:B1:7E:DD
+
</syntaxhighlight>
+
注:上述命令中的MAC地址请替换成手机实际的<br /><br />
+
这个命令会详细列出手机蓝牙所支持的协议,我们需要关心的是一个名为 OBEX Object Push 的文件传输服务,以MEIZU MX4手机为例,其显示结果如下所示:<br />
+
Service Name: OBEX Object Push<br />
+
Service RecHandle: 0x1000b<br />
+
Service Class ID List:<br />
+
"OBEX Object Push" (0x1105)<br />
+
Protocol Descriptor List:<br />
+
"L2CAP" (0x0100)<br />
+
"RFCOMM" (0x0003)<br />
+
Channel: 25<br />
+
"OBEX" (0x0008)<br />
+
Profile Descriptor List:<br />
+
"OBEX Object Push" (0x1105)<br />
+
Version: 0x0100<br />
+
<br />
+
从上面的信息可以看到,这个手机的OBEX Object Push服务的所用的频道是25, 我们需要将它传递给ussp-push命令,最后发起文件传输请求的命令如下:
+
<syntaxhighlight lang="bash">
+
ussp-push 38:BC:1A:B1:7E:DD@25 example.jpg example.jpg
+
</syntaxhighlight>
+
注:上述命令中的MAC地址、频道和文件名请替换成实际的<br /><br />
+
执行上述命令后,请留意手机屏幕,正常情况下手机会弹出配对和接收文件的提示,确定后就开始文件传輪了。<br />
+
<br />
+
蓝牙常见问题:<br />
+
1) 开发板上找不到蓝牙设备, 可尝试用以下命令开启蓝牙:<br />
+
<syntaxhighlight lang="bash">
+
rfkill unblock 0
+
</syntaxhighlight>
+
2) 提示找不到相关命令,可尝试用以下命令安装相关软件:<br />
+
<syntaxhighlight lang="bash">
+
apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push
+
</syntaxhighlight>
+
 
+
===安装Debian软件包===
+
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:
+
<syntaxhighlight lang="bash">
+
apt-get update
+
</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:
+
<syntaxhighlight lang="bash">
+
apt-get install vsftpd
+
</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。
+
 
+
===Debian系统HDMI或者3.5mm音频设备输出声音===
+
NanoPi M2A Debian系统默认接HDMI或者3.5mm耳机座没有输出声音,因为系统缺省没安装声音部分的安装包。如希望HDMI或者3.5mm耳机座接音频设备输出声音,需要给系统安装上缺省的alsa包。
+
* 首先,保证你的板子刷的是最新Debian固件,并且能连外网;
+
* 启动板子后,执行以下步骤安装alsa包:
+
<syntaxhighlight lang="bash">
+
apt-get update
+
apt-get install libasound2
+
apt-get install alsa-base
+
apt-get install alsa-utils
+
</syntaxhighlight>
+
* 安装好需要的库后,拷贝一首 .wav 格式的音乐到NanoPi M2A上,NanoPi M2A接上耳机或扬声器,播放音乐( Debian系统默认从3.5mm耳机座输出声音):
+
<syntaxhighlight lang="bash">
+
aplay music.wav
+
</syntaxhighlight>
+
* 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:
+
<syntaxhighlight lang="bash">
+
pcm.!default {
+
    type hw
+
    card 1
+
    device 0}
+
+
ctl.!default {
+
    type hw
+
    card 1}
+
</syntaxhighlight>
+
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HDMI即可输出声音。
+
 
+
==如何编译系统==
+
 
+
===安装交叉编译器===
+
首先下载并解压编译器:
+
<syntaxhighlight lang="bash">
+
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/
+
</syntaxhighlight>
+
 
+
然后将编译器的路径加入到PATH中,用vi编辑vi ~/.bashrc,在末尾加入以下内容:
+
<syntaxhighlight lang="bash">
+
export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH
+
export GCC_COLORS=auto
+
</syntaxhighlight>
+
 
+
执行一下~/.bashrc脚本让设置立即在当前shell窗口中生效,注意"."后面有个空格:
+
<syntaxhighlight lang="bash">
+
. ~/.bashrc
+
</syntaxhighlight>
+
 
+
这个编译器是64位的,不能在32位的Linux系统上运行,安装完成后,你可以快速的验证是否安装成功:
+
<syntaxhighlight lang="bash">
+
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
+

+
...
+
Thread model: posix
+
gcc version 4.9.3 (ctng-1.21.0-229g-FA)
+
</syntaxhighlight>
+
 
+
===编译U-Boot===
+
下载U-Boot源代码并编译,注意分支是nanopi2-lollipop-mr1:
+
<syntaxhighlight lang="bash">
+
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-
+
</syntaxhighlight>
+
 
+
编译成功结束后您将获得u-boot.bin,您可以通过fastboot来更新正在运行的NanoPi M2A板上SD的U-Boot,方法如下:<br />
+
1) 在电脑上先用命令 sudo apt-get install android-tools-fastboot 安装 fastboot 工具;<br />
+
2) 用串口配件连接NanoPi M2A和电脑,在上电启动的2秒内,在串口终端上按下回车,进入 u-boot 的命令行模式;<br />
+
3) 在u-boot 命令行模式下输入命令 fastboot 回车,进入 fastboot 模式;<br />
+
4) 用microUSB线连接NanoPi M2A和电脑,在电脑上输入以下命令烧写u-boot.bin:<br />
+
<syntaxhighlight lang="bash">
+
fastboot flash bootloader u-boot.bin
+
</syntaxhighlight>
+
<br />
+
注意:您不能直接使用dd来更新SD卡,否则有可能会导致无法正常启动。<br />
+
 
+
===准备mkimage===
+
编译内核需要用到U-Boot中的工具mkimage,因此,在编译内核uImage前,您需要保证您的主机环境可以成功运行它。<br />
+
你可以直接使用命令 sudo apt-get install u-boot-tools 来安装,也可以自己编译并安装:
+
<syntaxhighlight lang="bash">
+
cd uboot_nanopi2
+
make CROSS_COMPILE=arm-linux- tools
+
sudo mkdir -p /usr/local/sbin && sudo cp -v tools/mkimage /usr/local/sbin
+
</syntaxhighlight>
+
 
+
===编译Linux kernel===
+
====编译内核====
+
* 下载内核源代码
+
<syntaxhighlight lang="bash">
+
git clone https://github.com/friendlyarm/linux-3.4.y.git
+
cd linux-3.4.y
+
git checkout nanopi2-lollipop-mr1
+
</syntaxhighlight>
+
NanoPC-T2内核所属的分支是nanopi2-lollipop-mr1,在开始编译前先切换分支。
+
* 编译Android内核
+
<syntaxhighlight lang="bash">
+
make nanopi2_android_defconfig
+
touch .scmversion
+
make uImage
+
</syntaxhighlight>
+
* 编译Debian内核
+
<syntaxhighlight lang="bash">
+
make nanopi2_linux_defconfig
+
touch .scmversion
+
make uImage
+
</syntaxhighlight>
+
编译成功结束后,新生成的内核烧写文件为 arch/arm/boot/uImage,此内核支持LCD输出,用于替换掉SD卡boot分区下的uImage。<br />
+
如果要支持HDMI,则需要使用 nanopi2_linux_hdmi_defconfig, 具体如下:
+
<syntaxhighlight lang="bash">
+
make nanopi2_linux_hdmi_defconfig
+
touch .scmversion
+
make uImage
+
</syntaxhighlight>
+
使用新的uImage 替换SD卡boot分区下的uImage.hdmi 即可支持HDMI 720p,如果要支持1080p,则需要修改内核配置:
+
<syntaxhighlight lang="bash">
+
touch .scmversion
+
make nanopi2_linux_hdmi_defconfig
+
make menuconfig
+
  Device Drivers -->
+
    Graphics support -->
+

        (0)  Display In  [0=Display 0, 1=Display 1]
+
              Resolution (1920 * 1080p)  --->
+
make uImage
+
</syntaxhighlight>
+
* 编译Ubuntu Core内核
+
本部分的编译方法和编译Debian内核是相似的,只需要使用不同的2个内核配置即可。<br />
+
LCD 输出:
+
<syntaxhighlight lang="bash">
+
make nanopi2_core-qt_defconfig
+
</syntaxhighlight>
+
HDMI输出:
+
<syntaxhighlight lang="bash">
+
make nanopi2_core-qt_hdmi_defconfig
+
</syntaxhighlight>
+
选择自己需要的内核配置后,使用以下命令即可编译生成uImage。
+
<syntaxhighlight lang="bash">
+
touch .scmversion
+
make uImage
+
</syntaxhighlight>
+
 
+
====如何使用新编译的内核====
+
* 更新SD卡上的内核
+
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 />
+
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。
+
 
+
* 更新eMMC上Android的内核
+
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 />
+
从eMMC启动时可通过以下方法来更新内核:<br />
+
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/nanopi2/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">
+
cd linux-3.4.y
+
make CROSS_COMPILE=arm-linux- modules
+
</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:
+
<syntaxhighlight lang="bash">
+
cd /opt/FriendlyARM/s5p4418/android
+
./vendor/friendly-arm/build/common/build-modules.sh
+
</syntaxhighlight>
+
其中 “/opt/FriendlyARM/s5p4418/android” 是指Android源代码的TOP目录,使用参数“-h”可查看帮助。<br />
+
编译成功结束后,会显示生成的内核模块。
+
 
+
===编译Android===
+
我们提供了两个版本的Android,分别为Android4.4和Android5.1,这两个版本的Android源码编译方法一样。
+
* 搭建编译环境
+
搭建编译Android的环境建议使用64位的Ubuntu 14.04,安装需要的包即可。
+
<syntaxhighlight lang="bash">
+
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
+
</syntaxhighlight>
+
更多说明可查看 https://source.android.com/source/initializing.html 。
+
 
+
* 下载Android5.1源代码
+
Android源代码的下载需要使用repo,其安装和使用请查看 https://source.android.com/source/downloading.html 。
+
<syntaxhighlight lang="bash">
+
mkdir android && cd android
+
repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi2-lollipop-mr1
+
repo sync
+
</syntaxhighlight>
+
其中“android”是指工作目录。<br />
+
 
+
如果需要使用Android4.4源码的,则执行以下步骤
+
<syntaxhighlight lang="bash">
+
mkdir android && cd android
+
repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi2-kitkat
+
repo sync
+
</syntaxhighlight>
+
通过  -b  指定不同的分支即可
+
 
+
* 编译系统
+
<syntaxhighlight lang="bash">
+
source build/envsetup.sh
+
lunch aosp_nanopi2-userdebug
+
make -j8
+
</syntaxhighlight>
+
编译成功完成后,目录 out/target/product/nanopi2/ 下包含可用于烧写的image文件。
+
::{| class="wikitable"
+
|-
+
|filename    || partition || Description 
+
|-
+
|boot.img    || boot      || -
+
|-  
+
|cache.img    || cache    || -
+
|-  
+
|userdata.img || userdata  || -
+
|-  
+
|system.img  || system    || -
+
|-  
+
|partmap.txt  || -         || 分区描述文件
+
|-  
+
|}
+
 
+
* 烧写到SD卡
+
如果是采用SD卡启动Android,可复制编译生成的image文件到sd-fuse_nanopi2/android/ 下,使用脚本即可烧到到SD卡,具体请查看[[#在Linux Desktop下通过脚本制作]]。
+
 
+
* 烧写到eMMC
+
成功编译Android后,可过2种方式烧写到eMMC,分别如下:<br />
+
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 />
+
连接USB线,然后PC端输入以下命令:
+
<syntaxhighlight lang="bash">
+
cd out/target/product/nanopi2
+
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>
+
2) 使用SD卡烧写 <br />
+
复制out/target/product/nanopi2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 />
+

  • 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 board's boot slot, press and hold the boot key (only applies to a board with onboard eMMC) and power on (with a 5V/2A power source). If the PWR LED is on and LED1 is blinking this indicates your board has successfully booted.

4.3 Flash image to eMMC with eflasher

  • Download eflasher image file

An image file's name is as : s5p4418-eflasher-OSNAME-YYYYMMDD.img.zip
The "OSNAME" is the name of an OS e.g. android, friendlycore and etc;
This image file is used for making an installation SD card and it contains a Ubuntu core system and a utility EFlasher;
Download s5p4418-eflasher-OSNAME-YYYYMMDD.img.zip to a host PC and get a windows utility win32diskimager.rar as well;

  • Make Installation SD Card with eflasher

Extract the package with a 7z utility and you will get a file with an extension ".img". Insert an SDHC card(minimum 8G or above) to a PC running Windows, run the Win32DiskImager utility as administrator, click on "Image File" to select your wanted file, select your SD card and click on "Write" to start flashing the Image to your SD card;
If your PC runs Linux you can command "dd" to extract the package and get an ".img" file and write it to your SD card;

  • Operate in GUI Window: Flash OS to eMMC

Insert your SD card to NanoPi-M2A, connect an HDMI monitor or LCD to your board, press and hold the "boot" key beside the Ethernet port, power on the board you will see a pop-up window asking you to select an OS for installation. Select your wanted OS and start installation.

  • Operate in Commandline Utility: Flash OS to eMMC

Insert an installation SD card to NanoPi-M2A, log into or SSH to your board and run the following command to start EFlasher:

sudo eflasher

4.3.1 Make Installation Card under Linux Desktop

  • 1) Insert your SD card into a host computer 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 has been recognized as "/dev/sdc". Or you can check that by commanding "cat /proc/partitions"

  • 2) Downlaod Linux script

git clone https://github.com/friendlyarm/sd-fuse_s5p4418.git
cd sd-fuse_s5p4418

  • 3) Here is how to make a Lubuntu desktop SD card
sudo ./fusing.sh /dev/sdx lubuntu

(Note: you need to replace "/dev/sdx" with the device name in your system)
When you run the script for the first time it will prompt you to download an image you have to hit “Y” within 10 seconds otherwise you will miss the download

  • 4) Run this command to make a complete image file:
sudo ./mkimage.sh lubuntu

More content please refre: Assembling the SD card image yourself

4.4 Extend SD Card Section

  • When Debian/Ubuntu is loaded the SD 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 SD 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)

4.5 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-M2A is connected to 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-M2A is connected to an HDMI monitor and it runs Debian by default it will set the resolution to the HDMI 720P configuration. If you want to modify the HDMI resolution to 1080P modify your kernel's configuration as explained above.

4.6 Update SD Card's boot parameters From PC Host

Insert your SD card into a host PC running Linux, if you want to change your kernel command line parameters you can do it via the fw_setevn utility.
Check the current Command Line:

git clone https://github.com/friendlyarm/sd-fuse_s5p4418.git
cd sd-fuse_s5p4418/tools
./fw_printenv /dev/sdx | grep bootargs

For example, to disable android SELinux, You can change it this way:

./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive

The "XXX" stands for the original bootargs' value.

4.7 Run Android or Linux (TODO)

  • 将制作好SD卡插入NanoPi-M2A,连接HDMI,按住靠近网口的boot按键,最后接电源(5V 2A)拨动开关,NanoPi-M2A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。
  • 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。

5 Work with FriendlyCore

5.1 Introduction

FriendlyCore is a light Linux system without X-windows, based on ubuntu core, It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

Besides the regular Ubuntu core's features our FriendlyCore has the following additional features:

  • it supports our LCDs with both capacitive touch and resistive touch(S700, X710, HD702, S430, HD101 and S70)
  • it supports WiFi
  • it supports Ethernet
  • it supports Bluetooth and has been installed with bluez utilities
  • it supports audio playing
  • it supports Qt 5.10.0 EGLES and OpenGL ES1.1/2.0 (Only for S5P4418/S5P6818)

5.2 System Login

  • If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
  • If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will

For example, NanoPi-M1:
PSU-ONECOM-M1.jpg
You can use a USB to Serial conversion board too.
Make sure you use a 5V/2A power to power your board from its MicroUSB port:
For example, NanoPi-NEO2:
USB2UART-NEO2.jpg

  • FriendlyCore User Accounts:

Non-root User:

   User Name: pi
   Password: pi

Root:

   User Name: root
   Password: fa

The system is automatically logged in as "pi". You can do "sudo npi-config" to disable auto login.

  • Update packages
$ sudo apt-get update

5.3 Configure System with npi-config

The npi-config is a commandline utility which can be used to initialize system configurations such as user password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following command to run this utility.

$ sudo npi-config

Here is how npi-config's GUI looks like:
npi-config

5.4 Develop Qt Application

Please refer to: How to Build and Install Qt Application for FriendlyELEC Boards

5.5 Setup Program to AutoRun

hcitool scan


Search results look like:

Scanning ...
    2C:8A:72:1D:46:02   HTC6525LVW

This means that a mobile phone named HTC6525LVW is searched. We write down the MAC address in front of the phone name, and then use the sdptool command to view the Bluetooth service supported by the phone:

sdptool browser 2C:8A:72:1D:46:02

Note: Please replace the MAC address in the above command with the actual Bluetooth MAC address of the mobile phone.
This command will detail the protocols supported by Bluetooth for mobile phones. What we need to care about is a file transfer service called OBEX Object Push. Take the HTC6525LVW mobile phone as an example. The results are as follows:

Service Name: OBEX Object Push
Service RecHandle: 0x1000b
Service Class ID List:
  "OBEX Object Push" (0x1105)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 12
  "OBEX" (0x0008)
Profile Descriptor List:
  "OBEX Object Push" (0x1105)
    Version: 0x0100

As can be seen from the above information, the channel used by the OBEX Object Push service of this mobile phone is 12, we need to pass it to the obexftp command, and finally the command to initiate the file transfer request is as follows:

obexftp --nopath --noconn --uuid none --bluetooth -b 2C:8A:72:1D:46:02 -B 12 -put example.jpg

Note: Please replace the MAC address, channel and file name in the above command with the actual one.

After executing the above commands, please pay attention to the screen of the mobile phone. The mobile phone will pop up a prompt for pairing and receiving files. After confirming, the file transfer will start.

Bluetooth FAQ:
1) Bluetooth device not found on the development board, try to open Bluetooth with the following command:

rfkill unblock 0

2) Prompt can not find the relevant command, you can try to install related software with the following command:

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

5.8 WiFi

For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:

Index Model
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601
6 5G USB WiFi RTL8821CU
7 5G USB WiFi RTL8812AU

You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:

  • Change to root
$ su root
  • Check device list
$ nmcli dev

Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.

  • Start WiFi
$ nmcli r wifi on
  • Scan Surrounding WiFi Sources
$ nmcli dev wifi
  • Connect to a WiFi Source
$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.

For more details about NetworkManager refer to this link: Use NetworkManager to configure network settings

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:

$ apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.


5.9 Ethernet Connection

If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP refer to: Use NetworkManager to configure network settings


5.10 Custom welcome message

The welcome message is printed from the script in this directory:

/etc/update-motd.d/

For example, to change the FriendlyELEC LOGO, you can change the file /etc/update-motd.d/10-header. For example, to change the LOGO to HELLO, you can change the following line:

TERM=linux toilet -f standard -F metal $BOARD_VENDOR

To:

TERM=linux toilet -f standard -F metal HELLO

5.11 Modify timezone

For exampe, change to Shanghai timezone:

sudo rm /etc/localtime
sudo ln -ls /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

5.12 Select the system default audio device

You can set the system default audio device by following the steps below.
Use the following command to view all the sound card devices in the system (Note: different development boards will have different results):

5.17 Power Off and Schedule Power On

“PMU Power Management” feature helps us to auto power on the board at a specific time, it is implemented by an MCU, support software power-off, and RTC alarm power-up functions.

Here’s a simple guide:
Turn on automatically after 100 seconds. (Time must be greater than 60 seconds.):

$ sudo echo 100 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

After setting up the automatic boot, turn off board with the 'poweroff’ command:

$ sudo poweroff

Cancel automatic boot:

$ sudo echo 0 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

Query the current settings, in the front is current time, followed by the time of automatic booting: If no automatic boot is set, it will display "disabled”.

$ sudo cat /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm


Note that some older versions of hardware may not support this feature, if you don't see this file node in your system:
/sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm
your board may be it does not support this feature.

6.5 Optimizing HDMI Performance on Android 7

6.5.1 Note

By default, the driver initializes two framebuffers, one for the primary LCD display and the other for HDMI. If your project specifically requires the use of HDMI and not the LCD, you can follow the steps outlined in this chapter to make modifications. After making these changes, HDMI will be configured as the primary display, resulting in the initialization of only one framebuffer. This optimization conserves resources and leads to corresponding improvements in UI performance and boot speed.
The content of this chapter is applicable exclusively to S5P6818 running Android 7. For S5P4418, the modification process is similar, with adjustments needed in the corresponding files.

6.5.2 Modify the kernel

You need to modify the kernel Device Tree Source (DTS) to disable the dp_drm_lvds node, as shown below:

--- a/arch/arm64/boot/dts/nexell/s5p6818-nanopi3-common.dtsi

                clock-frequency = <50000000>;

After compilation, you will obtain a new arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb file.
During the testing phase, you can directly update it to the board using adb with the following command:

adb root; adb wait-for-device; adb shell mkdir /storage/sdcard1/; adb
shell mount -t ext4 /dev/block/mmcblk0p1 /storage/sdcard1/
adb push arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb /storage/sdcard1/

For a complete firmware update, you will need to replace the files in the device/friendlyelec/nanopi3/boot directory of the Android 7 source code.

6.5.3 Modify env.conf

To modify the device/friendlyelec/nanopi3/boot/env.conf file and add a line

lcdtype     HDMI1080P60

This mode needs to match the mode detected by Android 7 after startup; otherwise, it may result in a prolonged black screen state or even no display output. In such cases, you may need to manually set it in the U-Boot command-line environment:

setenv lcdtype HDMI1080P60; saveenv; reset

6.5.4 Modify system.prop

To modify the device/friendlyelec/nanopi3/system.prop file in Android 7

ro.sf.lcd_density=240

Alternatively, you can adjust the system property or experiment with different values that you deem more appropriate. You can also use the following command to change the display density under the serial or adb environment and observe if the effect is suitable:

adb shell wm density 240

6.5.5 Compiling Android

Follow the instructions in the wiki to compile Android 7 and conduct testing. If you encounter any exceptions, please carefully review the preceding steps.

8 Make Your Own OS Image

8.1 Install Cross Compiler

8.1.1 Install arm-linux-gcc 4.9.3

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

8.2 Compile Linux kernel for FriendlyCore/Lubuntu/EFlasher

8.2.1 Compile Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
cd linux

The NanoPi-M2A's kernel source code is in the "nanopi2-v4.4.y" branch.You need to switch to this branch.

  • Compile Ubuntu Kernel
touch .scmversion
make ARCH=arm nanopi2_linux_defconfig
make ARCH=arm

After your compilation succeeds an "arch/arm/boot/zImage" will be generated and a DTB file(s5p4418-nanopi2-rev*.dtb) will be generated in the "arch/arm/boot/dts/" directory. You can use them to replace the existing zImage and DTB files in the boot partition of your bootable SD card.

8.2.2 Use Your Generated Kernel

  • Update kernel in SD card

If you use an SD card to boot Ubuntu you can copy your generated zImage and DTB files to your SD card's boot partition(e.g. partition 1 /dev/sdX1).

  • Update kernel in eMMC

If you boot your board from eMMC you can update your kernel file by following the steps below:
1) Usually after OS is loaded eMMC's boot partition (in our example eMMC's device name was /dev/mmcblk0p1) will be automatically mounted and you can verify that by running "mount"
2) Connect your board to a host PC running Ubuntu and copy the zImage and DTB files to eMMC's boot partition
3) Or you can copy your generated kernel file to an external storage card(e.g. an SD card or a USB drive), connect the storage card to your board the move the file from the card to eMMC's boot partition
4) After update is done type "reboot" to reboot your board. Note: don't just directly disconnect your board from its power source or press the reset button to reboot the board. These actions will damage your kernel file

  • Generate Your boot.img

Refer to this repo: https://github.com/friendlyarm/sd-fuse_s5p4418

8.3 Compile Linux kernel for Android7

The Android 7.1.2 source code already contains the pre-compiled kernel. If you need to customize it, you can compile the kernel according to the following guide.

git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
cd linux
touch .scmversion
make ARCH=arm nanopi2_nougat_defconfig
make ARCH=arm

The newly generated kernel is arch/arm/boot/zImage,The new DTB file is also included under the directory arch/arm/boot/dts/.(s5p4418-nanopi2-rev*.dtb).
If you only want to debug the kernel, you can quickly update it with adb:

adb root; adb shell mkdir /storage/sdcard1/; adb shell mount -t ext4 /dev/block/mmcblk0p1 /storage/sdcard1/;
adb push arch/arm/boot/zImage arch/arm/boot/dts/s5p4418-nanopi2-rev*.dtb /storage/sdcard1/

If you want to generate boot.img for burning, you can copy the kernel zImage and DTB files to the Android7 source code directory: device/friendlyelec/nanopi2/boot, then recompile Android7.

8.4 Compile U-Boot for Android7/FriendlyCore/Lubuntu/EFlasher

Download the U-Boot source code and compile it. Note that the github's branch is nanopi2-v2016.01:

git clone https://github.com/friendlyarm/u-boot.git 
cd u-boot
git checkout nanopi2-v2016.01
make s5p4418_nanopi2_defconfig
make CROSS_COMPILE=arm-linux-

After your compilation succeeds a bootloader.img will be generated. If you want to test it flash it to your installation SD card to replace an existing U-Boot v2016.01 file via fastboot, sd-fuse_s5p4418 or eflasher ROM.
For Android7: Copy bootloader.img to Android7 source directory device/friendlyelec/nanopi2/boot, then recompile Android7.
Note: you cannot use mixed U-Boot files. For example you cannot use fastboot to update an existing U-Boot V2014.07 and you cannot use bootloader.img to replace an existing u-boot.bin

8.5 Compile Android 7.1.2

8.5.1 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 curl libncurses5-dev libssl-dev zlib1g-dev gawk minicom
sudo apt-get install openjdk-8-jdk
sudo apt-get install exfat-fuse exfat-utils device-tree-compiler liblz4-tool

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

8.5.2 Download Android7 Source Code

There are two ways to download the source code:

  • repo archive file on netdisk

Netdisk URL: Click here
File location on netdisk:sources/s5pxx18-android-7.git-YYYYMMDD.tar (YYYYMMDD means the date of packaging)
After extracting the repo package from the network disk, you need to execute the sync.sh script, which will pull the latest code from gitlab:

tar xvf /path/to/netdisk/sources/s5pxx18-android-7.git-YYYYMMDD.tar
cd s5pxx18-android-7
./sync.sh
  • git clone from gitlab

NanoPi-M2A source code is maintained in gitlab, You can download it by running the following command:

  • If your NanoPi-M2A runs Android5.1 and it is connected to our LCD or an HDMI monitor after Android is fully loaded click on the "Camera" icon and the application will be started. You can take pictures or record videos

CMOS camera

  • Under Debian a camera utility "nanocams" is available for previewing 40 frames and picture taking. You can try it by following the commands below
sudo nanocams -p 1 -n 40 -c 4 -o IMG001.jpg

For more details about the usage of the nanocams run "nanocams -h". You can get its source code from our git hub:

git clone https://github.com/friendlyarm/nexell_linux_platform.git
  • Under FriendlyCore (kernel 4.4), You can try it by following the commands below:

Enter the following command to preview the video:

gst-launch-1.0 -e v4l2src device=/dev/video6 ! video/x-raw,format=I420,framerate=30/1,width=1280,height=720 ! nxvideosink

Enter the following command to start recording (VPU hardware encoding):

gst-launch-1.0 -e v4l2src device=/dev/video6 ! video/x-raw,format=I420,framerate=30/1,width=1280,height=720 ! tee name=t t. \
 ! queue ! nxvideosink t. ! queue ! nxvideoenc bitrate=12000000 ! mp4mux ! \
 filesink location=result_720.mp4

11.3 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-M2A 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-M2A:

  • Firstly you need to make sure your NanoPi-M2A is connected to the internet.Login to your NanoPi-M2A 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-M2A. You can test your camera with NanoPi-M2A'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-M2A to USB Keyboard & Run the Following Command:

./demo

opencv is successfully started

11.4 Connect NanoPi-M2A to Matrix GPS Module

  • The Matrix-GPS module is a small GPS module with high performance. It can be used in navigation devices, four-axle drones and etc.
  • The Matrix-GPS module uses serial communication. When the NanoPi-M2A is connected to the Matrix GPS module, after the NanoPi-M2A is powered up type in the following command in a terminal or click on the xgps icon it will be started.
$su - fa -c "DISPLAY=:0 xgps 127.0.0.1:9999"
  • Or on the Debian GUI start the LXTerminal, type in "xgps" and enter it will be started too.
