Using Method

Prepare the Hardware and Software

Hardware Requirement:

• Orange Pi 4G-IoT Development Board
• A PC for compilation with following specs:

64bit CPU
Up to 16GB RAM
UP to 40GB spare disk space
Operation system should up to Ubuntu12.04, it would be better if it is Ubuntu16.04
You could refer to Google file for more details: https://source.android.com/source/building

Software Requirement:

• Orange Pi 4G-IoT SDK
• Orange Pi 4G-IoT Firmware
• Android-image-flash-tool

Power Methods

There are two methods for power supply:

• DC （5V 2A）in for power:
• Battery in for power:

Usually use 3.7V battery to solder on the back side of the development board.

Before Usage

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.

Android Compilation Environment Construction

Download SDK compression package

• Android 6.0

Download the compression packages, corresponding to OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.00, OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.01, OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.14, a total of 15 volume compression packages. After obtaining the volume compressed packages, place all the compressed packages in the same directory, such as

Create directory:
mkdir OrangePi_4G-IOT_Android6.0
Copy Volume Compression Packet:
cp -rf OrangePi_4G-IoT_Android6.0_V1.0.tar.gz.*
OrangePi_4G-IOT_Android6.0/
Merge Compression Packet:
cat OrangePi_4G-IoT_Android6.0_V1.0.tar.gz.* >
OrangePi_4G-IOT_Android6.0.tar.gz
Unzip:
tar xzvf OrangePi_4G-IOT_Android6.0.tar.gz

• Android 8.1

After downloaded compression package, you will have 11packages named x00, x01, x02, x03 ...x10.Put packages on the same directory like the following:

Create directory
mkdir OrangePi_4G-IOT_Android8.1
Copy compress package
cp -rf x00 x01 x02 ... x10
Merge compression package
cat x*>OrangePi_4G-IOT_Android8.1.tar.gz
Decompression
tar xzvf OrangePi_4G-IOT_Android8.tar.gz

Construct Compilation Environment

It could also refer to Google file: [http://source.android.com/source/initializing.html

http://source.android.com/source/initializing.html]

• Install JDK

Compilation of Android6.0 is based on JAVA7, it needs to first install OpenJDK before compilation.

Command for installing:

sudo apt-get install openjdk-7-jdk

Configure environment variable of JAVA, here is the path for installation:

/usr/lib/jvm/java-7-openjdk-amd64

It could configure on the terminal with the following command:

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

• Install Software Package

For Ubuntu12.04:

sudo apt-get update
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

For Ubuntu14.04：

sudo apt-get update
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

We could process to SDK compilation after finished the above.

Compilation of SDK Source Code

There are many compilation shell scripts for development.

• Android 6.0

The directory would be: SDK/code/orangepi/scripts

$ cd code/orangepi/scripts
$ ls
anr_LM.sh auto.sh clean.sh codegen.sh init_project.sh tar_img.sh

auto.sh is automatically compilation script
clean.sh automatically scavenging the compiled result script

On the directory of code/orangepi/scripts, execute the automatically compilation script:

$ ./auto.sh IoT_bd6737m_35g_b_m0_op_smt_hd720_pcb_v2 v00 eng

The meaning of the parameter is:

1. $1 project_info [eg: IoT_bd6737m_35g_b_m0_op_smt_hd720_pcb_v2]
   
2. $2 version_info [eg: v00 v01 ...]
   
3. $3 compile_mode [eng:user userdebug eng]

• Android 8.1

The directory would be: SDK/code/orangepi/scripts

$ cd code/orangepi/scripts
$ ls
anr_LM.sh auto.sh clean.sh codegen.sh init_project.sh tar_img.sh

auto.sh--scripts for automatic compilation
clean.sh--scripts for automatically cleaning the compiled result

On the directory of code/orangepi/scripts, execute automatic compilation scripts:

$ ./auto.sh IoT_k37mv1_bsp_ry_smt_hd720_pcb_v2 v00 eng

Definition of the three parameters:

1. $1 project_info [eg: IoT_k37mv1_bsp_ry_smt_hd720_pcb_v2]
   
2. $2 version_info [eg: v00 v01 ...]
   
3. $3 compile_mode [eng:user userdebug eng]
   

Execute command to compile:
source build/envsetup.sh
luncher >full_k37mv1_bsp-eng
make -j4

Module compilation
Here would take an example of only compilation launcer:
mm packages/apps/Launcher3/ or enter into directory of packages/apps/Launcher3/, execute mm
Please note that some modules depend on the relationship of package, you need to run mma.

Generated Firmware

• Android6.0

After compiled, the firmware will gather in the directory of: code/IoT_op_smt_hd720_pcb_v2, pack it and name it like the following: IoT_op_smt_hd720_pcb_v2_v00_eng_20180126140300.tar.gz

$ tree IoT_op_smt_hd720_pcb_v2 IoT_op_smt_hd720_pcb_v2
