=== '''Download Linux Source Code''' ===
<br>
You could download the source code from the official website: <br>
http://www.orangepi.online/downloadresources/
<div>[[文件:Orange-pi-pc2-img48.png|800px|]]</div>
<br>
Subsection and compress the file, then unzip it after finish downloaded:

<br>
buildroot: Project compilation script<br>
brandy: gcc-linaro, boot and uboot source code and open source cross compiler tool<br>
linux-3.10: Kernel source code <br>
tools: Tools of project compilation <br>
build.sh: compilation script<br>
<br>
=== '''Compile Project Source Code''' ===
<br>
You need to compile the entire project while it is your first time to use the source code. You can use the following commands in the /lichee directory to complete the project:<br>
* Enter into content of lichee, command<br>
$ ll -a<br>
Check if there is an executable permission on build.sh, if not, modify the permissions<br>
$ chmod 755 build.sh<br>
* If there is .buildconfig after commanded ll –a, delete it<br>
$ rm –rf .buildconfig
<div>[[文件:Orange-pi-pc2-img50.png|800px|]]</div>
<br>
* Use the following command to compile the entire project<br>
$ ./build.sh config
<div>[[文件:Orange-pi-pc2-img51.png|800px|]]</div>
<br>
At this point the system will prompt the choice of the chip, as shown below, for OrangePi, select sun50iw2p1<br>
At this point, the system will be prompted to select the platform, as shown below, for OrangePi, select Android<br>
At this point, the system will be prompted the choice of the board, as shown below, for the OrangePi, select dolphin-p1

<br>
Appear this interface indicates waiting for the compiler.
<div style="padding-left:200px;">[[文件:Orange-pi-pc2-img53.png|400px|]]</div>
<br>
Wait fifteen minutes or so, compile complete.

=== '''Update the Kernel Image File and Replace Library''' ===
<br>
* After compilation is finished, the following files will be generated in the directory：
libs： lichee/out/sun50iw2p1/android/common/lib/modules/3.10.65 Download image from official website：<br>
http://www.orangepi.online/downloadresources/
<div>[[文件:Orange-pi-pc2-img55.png|800px|]]</div>
<br>
* Write the image：<br>
$ sudo dd bs=4M if=*.img of=/dev/sdb<br>
<br>
<div>[[文件:Orange-pi-pc2-img56.png|800px|]]</div>
<br>
Pull out the card reader, and then insert it again.<br>
At this time, the SD card is inserted into PC, view the SD card mount point (if you don't know how to get a mount point for the SD card, please refer to the diagram below).
<div>[[文件:Orange-pi-pc2-img57.png|800px|]]</div>
<br>
The first boot partition
<div>[[文件:Orange-pi-pc2-img58.png|800px|]]</div>
<br>
The second rootfs partition
<div>[[文件:Orange-pi-pc2-img59.png|800px|]]</div>
<br>
Copy the kernel image file generated by the compiler to the first partition (boot partition)<br>
Copy the lib library which generated after compilation to the second partition (rootfs partition)<br>
'''We would suggest using compilation system on github of official website.'''

<br>
=== '''Install JDK''' ===
<br>
The following will be illustrating jdk1.6 installation, it would be same for jdk1.7 installation.
* Download and install JDK, you will obtain jdk-6u31-linux-x64.bin
* Modify the permission of jdk-6u31-linux-x64.bin, which has no prior permission
* $./jdk-6u31-linux-x64.bin <br>
It will generate a folder:
<div>[[文件:Orange-pi-pc2-img66.png|800px|]]</div>
