Prepare source codePrepare source code package

1) Create a working directorycreate working directory Create ~/my-imx6 as working directorycreate ~/my-imx6 as working directory

$ mkdir ~/my-imx6

Create ~/my-imx6/02_source/imx_3.0.35_4.1.0 as the source code directory 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

Create ~/my-imx6/03_tools as tool directory create ~/my-imx6/03_tools as tool directory

$ mkdir ~/my-imx6/03_tools -p

2）Copy source code package to the development host copy source code package to the development host do it in this step in your own way. Tip: here copy “02_source code” from network disk to “~/my-imx6/02_source/imx_3.0.35_4.1.0” of Linux development host, and copy “03_tools/toolchain” from network disk to “~/my-imx6/03_tools” of Linux development host. tip: this step is to copy “02_source code”from network disk to “~/my-imx6/02_source/imx_3.0.35_4.1.0” of Linux development host.0”in development host，and copy “03_tool/toolchain”to “~/my-imx6/03_tools”。in development host

解压源码包 (decompress source code package)

1）解压u-boot源码和内核源码
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

2）解压交叉编译工具
decompress cross compiler tool

$ cd ~/my-imx6/03_tools/
$ tar jxf gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12.tar.bz2

开发环境配置(development environment configuration)安装需要的包 (install package needed)

1）更新源列表
list of updated source

$ sudo apt-get update

更新完成后如下图所示：
after update,it will look like below：

2）安装aptitude包管理工具和ia32-libs
install aptitude package management tool and ia32-libs
提示：如果编译主机的Linux是32位的，可以跳过此步骤。
tips：if Linux of compiler host is 32bit，you can skip this step。

• 安装aptitude包管理工具
  

install aptitude package management tool

$ sudo apt-get –y install aptitude

• Install ia32-libs with aptitude

install ia32-libs with aptitude

$ sudo aptitude –y install ia32-libs Tip: The following figure is a screenshot of the installation command executed again after aptitude and ia32-libs have been installed. tips: following is the screenshots with re-execution of installation command after installation of aptitude and ia32-libs is finished.

3) Install mkimage tool install mkimage tool

$ sudo apt-get -y install uboot-mkimage Tips: The following is the screenshots with re-execution of installation command after installation of mkimage tool is finished. tips：following is the screenshots with re-execution of installation command after installation of mkimage tool is finished. 4）Install ncurses-dev install ncurses-dev Instruction: make menuconfig is dependent on it. 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。 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

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
  write path to configured file
  $ sed -i "\$a IMX6_GCC462_PATH=$PWD" ~/my-imx6/03_tools/myimx6_3035_build_env
  • Write cross-compilation tool to configuration file
  37)]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 the configuration file view configured file
  $ cat ~/my-imx6/03_tools/myimx6_3035_build_env
  4) Figures attached
  Note: if an error occurs in any step, you need to delete ~/my-imx6/03_tools/myimx6_3035_build_env ，and operate again all steps of this segment.

  Compile(compilation)
  • Execute compilation
  execute compilation
  $ make Tip: In order to increase the compilation speed, “-j4” is added after 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.

  Write application
  1) Create application directorycreate application directory
  $ mkdir ~/my-imx6/02_source/application/ -p $ cd ~/my-imx6/02_source/application/
  2) Write application (here take hello.c as example) write application (here take hello.c as example create hello.c and write following code and save:
  • include
    
  int main(int argc, char **argv)
  {
  　　　printf("Hello, MYZR!\n");
  　　　
  　　　return;
  }
  
  3) 查看代码

  编译应用程序 (compile application)
  2) 编译
  compile
  $ ${CROSS_COMPILE}gcc hello.c -o hello.out
  
  注意：上面的命令有包含“$”号，即“${CROSS_COMPILE}gcc”，是引用我们source时产生的环境变量。
  note：the above commands contain charater“$”，e.g“${CROSS_COMPILE}gcc”，which is the environment variable generated when referring to our source。
  
  
  3) 查看目标文件类型
  view type of target file
  $ file hello.out you can get the property of target file hello.out. The file system package is located in the mirror folder corresponding to the network disk. The file system package is located in the image file folder in the network disk. As to type of file system supported and way of download please refer to《MY-IMX6 buring guide》. 1）Create directory of file system and entercreate directory of file system and enter$ mkdir ~/my-imx6/04_rootfs/ -p $ cd ~/my-imx6/04_rootfs/
  2）Copy file system to ~/my-imx6/04_rootfs/directory copy file system to ~/my-imx6/04_rootfs/directory this step sbould be done in your own way 3）Decompress file system to specified directory $ mkdir rootfs $ sudo tar jxf rootfs-linux.tar.bz2 -C rootfs
  Add application to file system (add application to file system)
  $ cp ~/my-imx6/02_source/application/hello.out rootfs/app_test/
  5）Re-pakcage file system $ rm -rf rootfs-linux.tar.bz2 $ cd rootfs/ $ sudo tar cjf ../rootfs-linux.tar.bz2 *
  Add module to file system(add module to file system)
  Prepare .ko file of module needed,as to other operations please refer to“add application to file system”.
