Android Compilation Environment Construction

Download SDK compression package

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

Create directory:
mkdir OrangePi_3G-IoT_Android4.4
Copy Volume Compression Packet to this directory:
cp -rf OrangePi_3G-IoT_Android4.4.tar.gz* OrangePi_3G-IoT_Android4.4/
Merge Compression Packet:
cat OrangePi_3G-IoT_Android4.4.tar.gz*>OrangePi_3G-IoT_Android4.4.tar.gz
Unzip:
tar xzvf OrangePi_3G-IoT_Android4.4.tar.gz

Construct Compilation Environment

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

• Install JDK

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

Command for installing:

sudo apt-get install openjdk-6-jdk
sudo apt-get install gcc-4.4

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
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

Full compilation
There are many compilation shell scripts for development.

Directory is: SDK/code/orangepi/scripts

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

auto.sh is automatically compilation script
clean.sh is automatically scavenging the compiled result script
tar_img.sh is packing script
One the directory of code/orangepi/scripts, we could execute automatically compilation script:

If the board is: 32g4g
$ ./auto.sh IoT03_mt6572_emmc_b1258_
32g4g_ry_smt_v1.1 v00 eng

If the board is: 4g2g
$ ./auto.sh IoT03L_mt6572_lca_b1258_
wg_4g2g_ry_smt_v1.1 v00 eng

The meaning of the parameter is:

1. $1 project_info [eg: IoT03L_mt6572
   _lca_b1258_wg_4g2g_ry_smt_v1.1]
   
2. $2 version_info [eg: v00 v01 ...]
   
3. $3 compile_mode [eng:user userdebug eng]
   

Module compilation
Usually use the following command to change Kernel file:
./mk -o=TARGET_BUILD_VARIANT=[user/userdebug/eng] projName n K && ./mk -o=TARGET_BUILD_VARIANT=[user/userdebug/eng] projName r bootimage

For example, if project is: hexing72_cwet_kk
./mk -o=TARGET_BUILD_VARIANT=eng hexing72_cwet_kk n k && ./mk -o=TARGET_BUILD_VARIANT=eng hexing72_cwet_kk r bootimage

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

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

After compilation, all the firmware will generate on the directory of:
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.

The previous "Android Firmware Burning" has introduced how to use the burning tool, so I won't go into details here, just open the burning tool directly.
a.We click on the far right of the Scatter-loading File column And select the path of Scatter File, as shown below.

b.Disconnect the board from the PC first, and click the Download button

c.Next, use a USB download cable to connect the host's USB to the machine's MircoUSB interface.

d.Only the lk and kernel were burned in the front. Since 3G-IoT-A only has 512M on-board storage, there is a problem of insufficient space, so you need to burn the rootfs to a TF card, and prepare a TF card with more than 8G and class10. After formatting. Burn roofs.img as follows

pv rootfs.img | sudo dd of=/dev/sdb bs=1M

sdb is the device file corresponding to the TF card
If it is a windows system, you can also use Win32DiskImager software to burn.

　Insert the tf card into the board, and it can start after power on. (Note that 3G-IoT-A and other two LED lights are on, then plug in the serial port, otherwise it will not start)

3G-IoT-B linux firmware burning

The board has 4G of onboard storage, so you can burn all the images directly to the onboard EMMC.
a.We click on the far right of the Scatter-loading File column
And select the path of Scatter File, as shown below

b . First disconnect the board from the PC and click the Download button

C. Next, use a USB download cable to connect the host's USB to the machine's MircoUSB interface. Burning completed

Start the system.
Connect the board to a 5V2A power adapter. Connect the serial port to see the system startup。

If the onboard space is not enough, you can burn the rootfs to the TF card. Proceed as follows.
Burn boot.img that supports mounting TF card rootfs
Click on the content in the box below

In the pop-up window, select boot_sd.img.

Download completed

Burn rootfs to TF card
Prepare a TF card above 8G and class10. After formatting. Burn roofs.img as follows

pv rootfs.img | sudo dd of=/dev/sdb bs=1M

sdb is the device file corresponding to the TF card
If it is a windows system, you can also use Win32DiskImager software to burn.

Start the system
Insert the tf card into the board and start it after power on.

Serial Debugging Tool

First need to prepare a USB to TTL serial cable, need to support 921600 baud rate
The debugging serial port of 3G-IoT is serial port 1, which has been led to 40pin, and the baud rate is 921600.
Connect the serial cable as shown below. The functions of the different color lines are as follows:

• Black——GND
• Green——RX
• White——TX

Usage based on Windows platform

In the process of using Orange Pi for project development, in order to get more debugging information, Orange Pi defaults support serial port information debugging. For developers, just prepare the materials mentioned above and can easily get serial debugging information. The serial port debugging tools used by different upper computers are similar, basically refer to the following ways to deploy. There are many tools for serial port debugging using the Windows platform. The commonly used tools are Putty. This section uses putty as an example for deployment.

• Install USB driver

Download the latest version of the driver PL2303_Prolific_DriverInstaller_v130.zip, download and extract.

Select application installation as an administrator

Waiting for installation and click.

• Download and install Putty

Putty can be downloaded from the address below, please choose the version that suits your development environment.

 https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Double-click the downloaded putty.exe to open putty. The software interface is shown below.

• Acquisition of device information

In Windows 7, we can check whether the serial port connection is normal and the serial port device No. through Device Manager. If the device is not recognized properly, please check if the driver is installed successfully. If there is a problem with the driver installation, try using the 360 Driver Master to scan the installation driver.

• Putty configuration

Set the serial port to the corresponding port number (COM4), turn off the flow control, and set the speed to 921600.

• Start debugging serial output

When the Orange Pi is powered on, putty will automatically print the serial port log information.

Usage based on Linux platform

There is a little difference using putty between Windows platform and Linux platform. The following mainly explains the differences. All operations are based on the Ubuntu 14.04 system.

• Install and start Putty

$ sudo apt-get install putty
$ sudo putty

• Configuration Putty

The serial port number can be viewed via ls /dev/ttyUSB*
The baud rate needs to be set to 921600
And turn off flow control

Other settings

Connect WIFI

To configure wireless, must know ssid and psk (account, password), enter the corresponding wlan*, ssid, psk
$ sudo vi /etc/network/interfaces
(add the following)
auto wlan0
iface wlan0 inet dhcp
wpa-ssid xxxx
wpa-psk xxxx
Then execute /etc/init.d/networking restart,wireless connected.

Usage of GPIO

Modify and Display of the GPIO Status Under ADB Mode

Get the Open/Close Status of GPIO : cat /sys/devices/virtual/misc/mtgpio/pin

Enter the command under ADB mode: cat /sys/devices/virtual/misc/mtgpio/pin , then it will show：

pin: [mode] [pull_sel] [din] [dout] [pull en] [dir] [ies] [smt]

0:11101010

1:01101010

、、、、、、

22:1-100-10-1-1

、、、、、、、

42：00000110


Corresponding meaning per row：

IO Number：mode，pull select，input value，output value，pull enable，direction，ies

Modify the Status of GPIO：

You could get the 40pin GPIO specifications from this manual or from schematic which have been uploaded to our official website: http://www.orangepi.org/downloadresources/. For example the 37th pin on 40pins is GPIO123,

echo -wdout123 1 > pin -This is Set the GPIO to output high level

echo -wdout123 0> pin -This is Set the GPIO to output high level
