= '''Prepare source code pacakge'''=
----
== '''3.0.35 Version code'''==

=== u-boot Source code ===
Filename:u-boot-2009.08--svn*.tar.xz 

=== kernel Source code ===
Filename：linux-3.0.35--svn*.tar.xz 

=== Cross compilation tool===
Filename：gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12.tar.bz2 

= '''Configuration compilation environment'''=
----
== '''Prepare source code'''==

=== Prepare source code package===
1）Create working directory 
*Create ~/my-imx6 as working directory 
$ mkdir ~/my-imx6 
[[File: myimx6l3035_build_2.1.1.1.jpg]] 
*Create ~/my-imx6/02_source/imx_3.0.35_4.1.0 as source code directory. 
$ mkdir ~/my-imx6/02_source/imx_3.0.35_4.1.0 -p 
[[File: myimx6l3035_build_2.1.1.2.jpg]] 
*Create ~/my-imx6/03_tools as tool directory 
$ mkdir ~/my-imx6/03_tools -p 
[[File: myimx6l3035_build_2.1.1.3.jpg]] 

2）Copy source code package to the development host 
Do it in this step in your own way. 
''Tip：this step is to copy “02_source code”from network disk to “~/my-imx6/02_source/imx_3.0.35_4.1.0”in development host，and copy “03_tool/toolchain”to “~/my-imx6/03_tools”.''in development host. 

=== Decompress source code package===
1）Decompress u-boot source code and kernel source code. 
$ cd ~/my-imx6/02_source/imx_3.0.35_4.1.0 
$ tar xf u-boot-2009.08--svn*.tar.xz 
$ tar xf linux-3.0.35--svn*.tar.xz 
[[File: myimx6l3035_build_2.1.2.1.jpg]] 

2）Decompress cross compiler tool 
$ cd ~/my-imx6/03_tools/ 
$ tar jxf gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12.tar.bz2 
[[File: myimx6l3035_build_2.1.2.2.jpg]] 

== '''Development environment configuration'''==
=== Install package needed===
1）List of updated source 
$ sudo apt-get update 
[[File: myimx6l3035_build_2.2.1.1.jpg]] 
After update,it will look like below： 

[[File: myimx6l3035_build_2.2.1.2.jpg]] 

2）Install aptitude package management tool and ia32-lib. 
''Tips：if Linux of compiler host is 32bit，you can skip this step. 

*Install aptitude package management tool. 
[[File: myimx6l3035_build_2.2.1.3.jpg]] 
$ sudo apt-get –y install aptitude 

* Install ia32-libs with aptitude. 
$ sudo aptitude –y install ia32-libs 
''Tips：following is the screenshots with re-execution of installation command after installation of aptitude and ia32-libs is finished. 
[[File: myimx6l3035_build_2.2.1.4.jpg]] 

3）Install mkimage tool 
$ sudo apt-get -y install uboot-mkimage 
''Tips：following is the screenshots with re-execution of installation command after installation of mkimage tool is finished. 
[[File: myimx6l3035_build_2.2.1.5.jpg]] 

4）Install ncurses-dev 
Instruction：make menuconfig is dependent on it. 
$ sudo aptitude -y install ncurses-dev 

''Tips：following is the screenshots with re-execution of installation command after installation of ncurses-dev tool is finished. 
[[File: myimx6l3035_build_2.2.1.6.jpg]] 

=== Configure environment variables of MY-IMX6 compilation===
1）Write platform information to a new configured file. 
$ echo "export ARCH=arm" > ~/my-imx6/03_tools/myimx6_3035_build_env 

2）Write compiler tool chain path to configured file. 
* Enter cross compiler tool directory 
$ cd ~/my-imx6/03_tools/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/ 
* Write path to configured file. 
$ sed -i "\$a IMX6_GCC462_PATH=$PWD" ~/my-imx6/03_tools/myimx6_3035_build_env 
* Write cross compiler tool to configured file 
$ sed -i "\$a export CROSS_COMPILE=\$IMX6_GCC462_PATH/arm-none-linux-gnueabi-" ~/my-imx6/03_tools/myimx6_3035_build_env 

3）View configured file 
$ cat ~/my-imx6/03_tools/myimx6_3035_build_env 

4）Figures 
[[File: myimx6l3035_build_2.2.2.1.jpg]] 

Note：If an error occurs in any step, need to delect ~/my-imx6/03_tools/myimx6_3035_build_env ，and operate again all steps of this segment.

== '''Compilation'''==
* Execute compilation 
$ make 
''Tips：To speed up the compilation，add "-j4" after make.The Linux host used to compile is dual-core ,4 threads .So "-j" is followed by 4, which takes 4 threads to compile. The number behind "-j" is allocated based on system resources,but It should not exceed the maximum threads the host support. 
[[File: myimx6l3035_build_3.5.0.1.jpg]]
