You can use it to build…<br>

*A A computer*A A wireless server*~~Games~~Games*~~Music~~ Music and sounds*~~HD~~ HD video*A A speaker*~~Android~~Android*~~Scratch~~Scratch

Pretty much anything else, because Orange Pi 3G-IOT is open source.<br>

<br>

=== '''Prepare the Hardware and Software''' ===

<br>

Hardware Requirement:<br>

* Orange Pi 3G-IoT Development Board

* A PC for compilation with following specs:<br>

64bit CPU<br>

Up to 16GB RAM<br>

UP to 40GB spare disk space<br>

Operation system should up to Ubuntu12.04, it would be better if it is Ubuntu16.04

</p>

You could refer to Google file for more details:    https://source.android.com/source/building<br>

<br>

Software Requirement:<br>

* Orange Pi 3G-IoT SDK

* Orange Pi 3G-IoT Firmware

* Android-image-flash-tool

<br>

=== '''Power Methods''' ===

<br>

There are two methods for power supply:<br>

* Micro USB（5V 2A）in for power:

* Battery in for power:

Usually use 4.2V battery to solder on the back side of the development board.<br>

<br>

=== '''Before Usage''' ===

<br>

After receiving the product, please put the antennas of the product from the position of Pic 1 to the position of Pic 2 (or to the outside of the board), which can not be attached to the board so as not to affect the signal.<br>

== '''Android Compilation Environment Construction''' ==

<br>

=== '''Download SDK compression package''' ===

<br>

Orange Pi offers different versions of SDK initial compression packages to facilitate customer rapid development.<br>

Download the compression packages, corresponding to OrangePi_3G-IoT_Android4.4.tar.gz00, OrangePi_3G-IoT_Android4.4.tar.gz01, ...OrangePi_3G-IoT_Android4.4.tar.gz00, a total of eight volume compression packages. After obtaining the volume compressed packages, place all the compressed packages in the same directory, such as<br>

<br>

<span style="font-weight:600;">Create directory:</span><br>

mkdir OrangePi_3G-IOT_Android4.4<br>

<span style="font-weight:600;">Copy Volume Compression Packet to this directory:</span><br>

cp -rf OrangePi_3G-IoT_Android4.4.tar.gz* OrangePi_3G-IOT_Android4.4/ <br>

<span style="font-weight:600;">Merge Compression Packet:</span><br>

cat OrangePi_3G-IoT_Android4.4.tar.gz*>OrangePi_3G-IOT_Android4.4.tar.gz <br>

<span style="font-weight:600;">Unzip:</span><br>

tar xzvf OrangePi_3G-IOT_Android4.4.tar.gz

</div>

<br>

=== '''Construct Compilation Environment''' ===

<br>

It could also refer to Google file: <span style="color:#808080;">http://source.android.com/source/initializing.html</span>

* '''Install JDK'''

Compilation of Android4.4 is base on JAVA6, it needs to first install OpenJDK, gcc4.4 before compilation.<br>

<br>

Command for installing:

sudo apt-get install openjdk-6-jdk <br>

sudo apt-get install gcc-4.4

</div>

<br>

If the installation path is /usr/lib/jvm/jdk1.6.0_31 when configure environment variable of JAVA, then execute the the following command on terminal to configure the data.

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_31<br>

export PATH=$JAVA_HOME/bin:$PATH<br>

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

</div>

=== '''Install Software Package''' ===

For Ubuntu12.04:

sudo apt-get update<br>

sudo apt-get install git-core gnupg flex bison ccache gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind libc6-dev lib32ncurses5-dev x11proto-core-dev

libx11-dev lib32readline-gplv2-dev lib32z1-dev libgl1-mesa-dev gcc-4.4 g++-4.4 g++-4.4-multilib g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc wine

</div>

<br>

For Ubuntu14.04:

sudo apt-get update<br>

sudo apt-get install git-core gnupg flex bison ccache gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind libc6-dev lib32ncurses5-dev x11proto-core-dev

libx11-dev lib32readline-gplv2-dev lib32z1-dev libgl1-mesa-dev g++-multilib g++-4.8-multilib mingw32 tofrodos python-markdown

libxml2-utils xsltproc libc6-dev-i386 lib32z1 lib32ncurses5 lib32bz2-1.0 lib32readline-gplv2-dev wine

</div>

We could process to SDK compilation after finished the above.<br>

<br>

=== '''Compilation of SDK Source Code''' ===

<br>

'''Full compilation'''

<br>

There are many compilation shell scripts for development. <br>

<br>

Directory is: SDK/code/orangepi/scripts

$ cd code/orangepi/scripts<br>

$ ls<br>

anr_kk.sh auto.sh clean.sh init_project.sh tar_img.sh

</div>

auto.sh is automatically compilation script<br>

clean.sh is automatically scavenging the compiled result script <br>

tar_img.sh is packing script<br>

One the directory of code/orangepi/scripts, we could execute automatically compilation script:

If the board is: 32g4g<br>

$ ./auto.sh IoT03_mt6572_emmc_b1258_32g4g_ry_smt_v1.1 v00 eng<br>

<br>

If the board is: 4g2g<br>

$ ./auto.sh IoT03L_mt6572_lca_b1258_wg_4g2g_ry_smt_v1.1 v00 eng

</div>

The meaning of the parameter is:<br>

#$1 project_info [eg: IoT03L_mt6572_lca_b1258_wg_4g2g_ry_smt_v1.1] <br>

#$2 version_info [eg: v00 v01 ...]<br>

#$3 compile_mode [eng:user userdebug eng]<br>

<br>

'''Module compilation'''

<br>

Usually use the following command to change Kernel file:<br>

./mk -o=TARGET_BUILD_VARIANT=[user/userdebug/eng] projName n K && ./mk -o=TARGET_BUILD_VARIANT=[user/userdebug/eng] projName r bootimage<br>

<br>

For example, if project is: hexing72_cwet_kk<br>

./mk -o=TARGET_BUILD_VARIANT=eng hexing72_cwet_kk n k && ./mk -o=TARGET_BUILD_VARIANT=eng hexing72_cwet_kk r bootimage<br>

<br>

You could refer to MT6592_Driver_All_In_One_Part.pdf (after unzip SDK you will have this file) for modification of driver compilation.

== '''Android Firmware Flashing''' ==

<br>

Relevant keys and connectors for firmware flashing of 3G-IOT:

<div style="padding-left:200px;">[[文件:Orange-pi-3g-iot-img6.png|800px|]]</div>

After compilation, all the firmware will generate on the directory of:<br>

code/IoT03_b1258_32g4g_ry_smt_v1.1 or code/IoT03L_b1258_wg_4g2g_ry_smt_v1.1 , and packed into compression file as the name of IoT03L_b1258_wg_4g2g_ry_smt_v1.1_20180403182516_v00_eng.zip.

<br>

After the above steps, you could refer to the previous section to flash image.<br>

<br>

Or you could use the image we have compiled and pack: http://www.orangepi.online/downloadresources/ Unzip Android4.4 image via the following command:

$ rar x IoT03L_b1258_wg_4g2g_ry_smt_v1.1.rar

</div>

You could get the list of firmware after ran the above command, or you could also compile by yourself with reference of previous section.<br>

<br>

'''Supporting OS of PC:'''

* Windows 10

* Windows 7 (32/64bit)

* Windows 8 (32/64bit)

<br>

=== '''Flash Tool Introduction''' ===

<br>
