You could use HDMI cable to connect your Orange Pi to HDMI TV or monitor.You could also use AV interface and audio interface to connect output video and audio to analog TV or display. c.Insert USB keyboard and mouse into the USB interface. d.It is the network port in the middle of 3USB interfaces, which you can access Orange Pi to the wired network. e.It is the power input interface on the right side for connecting a power adapter up to or bigger than 5V/2A. Avoid using smaller power GSM mobile phone charger, it is not able to output 2A even if it marked "5V/2A ". Note: Micro-USB（OTG）cannot use as power input which may cause the fail boot of the OrangePi. Only the power interface could input power. The Orange Pi will boot in a few minutes If the above steps are successful. There will be graphical interface in he monitor. It may take a long time to start the first time, please wait patiently. The next time will boot very fast. === '''Step 4: Turn off your Orange Pi Correctly''' === * You can use the shutdown button on the interface to safety close the Orange Pi.* You can also close the system by entering commands in the shell: '''sudo halt''' or '''sudo shutdown –h''' It will be safety to turn off the Orange Pi. If directly use the power button to shut down the system may damage the file system on TF Card. After the system is closed, the power can be cut off by more than 5 seconds’ press. === '''Other configuration''' === '''1)Connect to the wired network''' If the Orange Pi has connect to wire cable, then the system would obtain the IP address automatically. If there is no wire cable connecting, then the system would fail at obtaining IP address which could cause the booting delay. After connecting to wired network, it should be green LED lighting and yellow LED flashing. You need to make sure the image you wrote is correspondent since some boards are 100M Ethernet but some are 1000M Ethernet. 100M Ethernet is using internal phy, configuration just like the following: 2 indicates internal phy<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img26.png|600px|]]</div> 1000M Ethernet is using external phy<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img27.png|600px|]]</div> The above configuration has been configured, you could refer to it when using. '''2)Login via vnc and ssh''' If there is no condition for connecting HDMI, you could enter the system via vnc or ssh remote login. * Login via serial port and install ssh apt-get install ssh* Modify ssh configuration file /etc/ssh/sshd_config <div style="padding-left:200px;">[[文件:Orange-pi-pc2-img28.4 png|400px|]]</div> * Check the IP with ifconfig, login via ssh of root user <div style="padding-left:200px;">[[文件:Orange-pi-pc2-img29.png|600px|]]</div> '''3)HDMI or 3.5mm Sound Output''' a.The sound was default to output via HDMI on image, it could check and change via alsamixer. ls /etc/asound.conf card indicates card number, device indicates device number. aplay -l it could check the system to load the sound card number and details cat /proc/asound/cards it also could check the sound card and details It could be used after use alsamixer to change the sound card. alsactl store -f /var/lib/alsa/asound.state used for saving modified parameters b.It needs to modify configuration on file systemfor output on 3.5mm of/etc/asound.conf, modify card1 into card0, or use amixer to modify. The default one is configured, or you could use player on graphical interface to switch via sound channel selection. c.How to use mic sound recording arecord -d 5 -f cd -t wav 123.wav After recording, use the following to play aplay 123.wav === '''Universal Software Configuration''' === '''1)Default Account Changing''' The default log in account is orangepi. In order to secure, it is recommended to modify the default orangepi accounts to your own account, for example Zhangsan. Steps are as follows: a.Use root account to login Orange Pi(please note that do not login with the account of orangepi b.$ usermod -l zhangsan orangepi Change orangepi account into Zhangsan<div style="padding-left:100px;">[[文件:Orange-pi-pc2-img30.png|400px|]]</div>c.$ groupmod -n zhangsan orangepi Change group<div style="padding-left:100px;">[[文件:Orange-pi-pc2-img31.png|400px|]]</div>d.$ mv /home/ornagepi /home/zhangsan Change directory of original orangepi<div style="padding-left:80px;">[[文件:Orange-pi-pc2-img32.png|600px|]]</div>e.$ usermod -d /home/orangepi orangepi Set this directory to orangepi user's home directory<div style="padding-left:80px;">[[文件:Orange-pi-pc2-img33.png|600px|]]</div>f.$ cat /etc/passwd It should be shown as below:<div>[[文件:Orange-pi-pc2-img34.png|800px|]]</div>After the modification of the above iterms, it can be used the new account Zhangsan to land. '''2)U Disk Automatic Mounted Configuration''' a.sudo apt-get install usbmount b.sudo vim /etc/udev/rules.d/automount.rules ACTION=="add",KERNEL=="sdb*", RUN+="/usr/bin/pmount --sync--umask 000 %k" ACTION=="remove", KERNEL=="sdb*", RUN+="/usr/bin/pumount %k" ACTION=="add",KERNEL=="sdc*", RUN+="/usr/bin/pmount --sync--umask 000 %k" ACTION=="remove", KERNEL=="sdc*", RUN+="/usr/bin/pumount %k" c.udevadm control –reload-rules It could refer to this: http://unix.stackexchange.com/questions/134797/how-to-automatically-mou nt-an-usb-device-on-plugin-time-on-an-already-running-sy '''3)System Source Configuration''' Take Ubuntu as an example: a.Open the source file $ sudo vi /etc/apt/sources.list<div>[[文件:Orange-pi-pc2-img35.png|800px|]]

</div>

b.Edit source file

Replace the source file with your favorite source. Take an example of Ubuntu 16.04 on Zhonkeda source:

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

Note: xenial is the version of the code name in this source, if the other version of Ubuntu needs to replace the corresponding version code which can be found on the internet.

'''4)Remote desktop installation'''

There are a lot of software, such as VNG, XRDP, X2GO, etc. For X2GO, it has more functions, and desktop color restore is very good which does not need too much configuration. And XRDP is much more safety than VNC.

a.$sudo apt-get install tightvncserver Install VNC

<div>[[文件:Orange-pi-pc2-img36.png|400px|]]</div>

b.vncpassw Set the password: do not execute this command but executing vncserver directly. It will prompt you to enter the password twice, when prompted whether can be read only to select the N.

<div>[[文件:Orange-pi-pc2-img37.png|800px|]]</div>

c.Open one or more of desktops by vncserver or vncserver:1(vncserver:2)… you can also transfer more parameters through the full command as below:

vncserver :1 -geometry 1024x768 -depth 16 -pixelformat rgb565

(Note: If it prompted you that cannot find the file or other error when installing, please run sudo apt-get update to update the software source and try installing again.)

'''5)NAS and DLAN Configuration'''

a.NAS：

There are many files could be reference from Internet, for example: http://www.geekfan.net/5003/, it detailed descriptions on the operation and the mounted of U disk is very useful.

b.DLNA:

Mainly through the minidlna software to achieve the sharing of media resources within the LAN, such as sharing video, music, etc.. The installation steps are as follows:

i. sudo apt-get minidlna

ii. Execute the following command to modify the configuration file:

sudo nano /etc/minidlna.conf

Note: you can also use other text editor to modify.

iii. Add the following:

media_dir=A,/nas, path: /DLNA/Music

media_dir=V,/nas, path: /DLNA/Video

media_dir=P,/nas, path: DLNA/Picture

db_dir=/nas, path: /DLNA/log

db_dir=/nas, path: /DLNA/db

ctrl +o and enter, ctrl +x to save and exit.

iv. Established above folders respectively, noted that path consistency and assigned to read and write permissions. In order for convenient, it could be Chmod 755, such as sudo Chmod 755 /nas path /DLNA/Music

v. Re-start minidlna to take effect the configuration: /etc/init.d/minidlna restart.

Transmit the corresponding file on the computer to the corresponding folder through samba.

Note: It is recommended to download MoliPlayer on the mobile device. The effect is good and no blue light pressure on both Android and IOS.

'''6)Thunder remote download'''

a.Go to the Thunder routing forum to download the required installation package first. The link for stable version:

http://luyou.xunlei.com/thread-12545-1-1.html.

Download Xware1.0.31_cubieboard zip file.

<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img38.png|800px|]]</div>

Note: If you want to try the latest version, you can download the latest test version: http://luyou.xunlei.com/thread-15167-1-1.htm.

b.Enter the directory after uploaded the unzip file to OrangePi. It is recommended to rename the file to xunlei

c.Installation method of version 1.0.31:

iv Run ./etm_monitor, there will be an activation code page like

version 1.0.32. And then binding on the Thunder remote page (above steps 4, 5). There might be one or two errors while running, ignore it (selection type of shell and generation of INI file).

v Setting start up

sudo nano /etc/rc.loacl

add the following contents before exit 0

cd /xx/xunlei

./etm_monitor &

ctrl +o and enter, ctrl +x to save and exit.

It could be remote downloading on computer, mobile phone or tablet by login yuancheng.xunlei.com

'''7)Modify the size of ext4 file system'''

After made the written image into SD card for booting, enter into rootfs partition’s expansion of file system. It could enhance the performance of SD card to avoid limited storage cause prblem.

* Method 1

Extend rootfs file partition of TF card on PC:

Select the specified disk, right click and select the corresponding disk, select "change size" and adjust it into your desired size, click "resize", close the dialog box and click "apply all operations", select the application to complete the expansion operation

* Method 2

Enter into the system and extend via shell Before partition

<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img43.png|400px|]]</div>

Eneter into system and expend via resize_rootfs.sh

<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img44.png|400px|]]</div>

Enter resize_rootfs.sh on command line, the system will expending automatically,

Reboot the system and use df -lh to check whether expending is successful

<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img45.png|400px|]]</div>

a.Expand file system

i. Boot to Linux, umount /dev/sdb1 and /dev/sdb2, if it prompts disk busy, then use fuser to clean the using disk(we will recommend using another Linux booting disk to lead the system).

ii. Use fdisk /dev/sdb to adjust the partition size, after into it, enter p, and keep in mind about the initial position of needed extending size partition.

iii. Enter d to delete the partition need to change the size(my file system is /dev/sdb2, which is the 2 partition ).

iv. Enter n to build a new partition, make sure the initial position is the same as you deleted, and enter the number as you desire.

v. Enter w to save the partition data.

vi. Use the following command to check the file system(make sure it is a right file system)

e2fsck -f /dev/sdb2

vii. Adjust the partition size

resize2fs /dev/sdb2

viii. It could mount a disk partition, you could check whether it has changed.

b.Shrink file system

i. Boot to Linux, umount /dev/sdb1 and /dev/sdb2, if it prompts disk busy, then use fuser to clean the using disk(we will recommend using another Linux booting disk to lead the system).

ii. Use the following command to check the file system(make sure it is a right file system)

e2fsck -f /dev/sdb2

iii. Modify the size of file system(Use resize2fs)

resize2fs /dev/sdb2 900M

The "s"after the number represents specifying the size of file system via the sectors(every sector calculated by 512 bite). You could also specify it into K(KB), M(MB), G(GB), etc.

iv. Use fdisk /dev/sdb to adjust the partition size, after into it, enter p, and keep in mind about the initial position of needed extending size partition. You need to first delete the partition then build a new one because the fdisk could not modify the size dynamic(you need to calculate the size, it have to enough to contain the file system adjusted in last step).

v. Enter d to delete the partition need to change the size(my file system is /dev/sdb2, which is the 2 partition ).

vi. Enter n to build a new partition, make sure the initial position is the same as you deleted, and enter the number as you desire. Besides, if it is bootable partition you want to change, note that need to keep the bootable mark in case cannot boot.

The above illustration is using fdisk and resize2fs to modify partition and file system, you could also use gparted. Gparted has graphical interface and it could help you to re-size file system at the same time of re-sizing partition. Goarted is much easier to use and reduce the change to make mistake. For now our offial Lubuntu and Raspbian could not use it.

'''8)How to use gc2035 on Linux'''

a.Use find command to find the location of the following files, and load it according to the specified order

insmod videobuf-core.ko

insmod videobuf-dma-contig.ko

insmod uvcvideo.ko

insmod cci.ko

insmod vfe_os.ko

insmod vfe_subdev.ko

insmod gc2035.ko

insmod vfe_v4l2.ko

There should be generated video0 on /dev/ after loaded. After low-level driver install, then the Andoird could be used directory.

b. Use camera in Linux

i Load up driver

sudo modprobe gc2035

sudo modprobe vfe_v4l2

ii. Install motion

sudo apt-get install motion

iii. Modify configuration

sudo nano /etc/motion/motion.conf

stream_localhost off

iv. Create folder for images saving

mkdir ~/motion

v. Modify permission

chmod 777 motion

vi. Continue modifying configuration

sudo nano /etc/default/motion

start_motion_daemon=yes

vii. Boot the server

Sudo /etc/init.d/motion start

Enter the following in browser: localhost:8081

You could check image output from camera.

Besides, you could also refer to this link:

http://www.cnx-software.com/2015/09/26/how-to-use-orange-pi-camera-in-l inux-with-motion/

'''9)eth0 and wlan0 static mac address setting'''

a.If the system do not use systemd, you could modify rc.local directory and add the following:

$ vim /etc/rc.local

MAC=00:e0:4c:a1:2b:d4

ifconfig wlan0 down

ifconfig wlan0 hw ether $MAC

ifconfig wlan0 up

dhclient &

After rebooting, you could use ifconfig to check whether mac address has changed.

b.If the system used systemd, you also need to add the following besides the above steps:

$ cd /etc/systemd/system/

$ vim change_mac_address.service (You could name the server, format just like the following)

[unit]

Description=Change OrangePi Wifi mac address

[Service]

ExecStart=/etc/rc.local RemainAfterExit=yes

[Install]

sWantedBy=multi-user.target

$ systemctl enable change_mac_address.service

Modify mac address of eth0 is same as modifying wlan0’s, just need to replace wlan0 into eth0.

'''10)Orange Pi Android root'''

There is defaulted with root permission on Android pre-installed, but lacking authorization management software. The following is how to add authorization management software.

You need to have UsbModeSwitch.apk and UPDATE-SuperSU-v2.46.zip, install kingroot and make sure OTG on Orange Pi could connect to PC.

a.Open adb debug mode

Use U disk or card reader to install UsbModeSwitch.apk into Orange Pi OS and open it, tick "enable usb device mode" and use debug cable to connect OTG port and PC (make sure it is micro usb-cable in case other cables could not be recognized). Normally PC would search and install adb driver software automatically. If PC failed to install, you could install PC version’s Peasecod to install the driver software.

b.After connected Orange PI and PC, open command mode of PC, enter related command of adb(you need to install adb debug command, which Peasecod has adb command ). Here is the command:

adb remount

adb shell

windows(win+r) command line enter into command mode, then enter into kingroot directory and execute the following steps:

adb shell

root@rabbit-p1:/ # mkdir /tmp

root@rabbit-p1:/ # cd /system/bin

root@rabbit-p1:/ # mount -o remount, rw /system

root@rabbit-p1:/system/bin # ln -s busybox-smp unzip

Logout adb shell Mode

root@rabbit-p1:/exit (Or Ctrl + C)

Unzip UPDATE-SuperSU-v2.46.zip

You will obtain META-INF/com/google/android/update-binary and put it into specific catalog.

adb push /path/UPDATE-SuperSU-v2.46.zip /data/local/tmp path is file’s path

adb push /path/ update-binary /data/local/tmp

adb shell

root@rabbit-p1:/ #cd /data/local/tmp

root@rabbit-p1:/ #sh update-binary 0 1

/data/local/tmp/UPDATE-SuperSU-v2.46.zip

After executed scripts, enter reboot command and reboot it, you could use the device authorization management software normally.

After rebooted, there might be no super administrator icon, you need to delete the desk configuration file and reboot the board.

'''11)WiringPi installation and usage'''

a. Install WiringPi

i Install compilation tools for source code compilation

$ sudo apt-get install gcc g++ make

ii Compile GPIO driver of H5

git clone https://github.com/kazukioishi/WiringOP.git -b h5

cd WiringOP

chmod +x ./build
