编译(compilation)execute compilation
$ make
提示：这里为了提高编译速度，在make后面加了“-j4”。这里编译的Linux主机是双核4线程的，所以“-j”后面用了4，也就是采用4线程编译。“-j”后面的数字可以根据系统资源分配，但是不应该超过编译主机最大支持的线程数。
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。
complete compilation
提示：u-boot编译过程大概需要几分钟时间。
tips：u-boot compilation process will take a few minustes or so。
目标文件(target file)编译完成后通过ls命令即可看到编译得到的目标文件u-boot.bin
you can get the compiled file u-boot.bin with ls command after compilation
$ ls
编译内核(compile kernel)
进入内核源码目录(enter kernel source directory)$ cd ~/my-imx6/02_source/imx_3.0.35_4.1.0/linux-3.0.35/

准备配置内核(prepare for kernel configuration)remove kernel configuration
$ make distclean
generated.config file
说明：MY-IMX6-EK200系列评估板及MY-IMX6-EK314系列评估板使用的配置文件是myimx6_defconfig
instructions：configuration files used for MY-IMX6-EK200 seires of evaluation board and MY-IMX6-EK314 series of evaluation board is myimx6_defconfig
$ make myimx6_defconfig
编译内核(compile kernel)compile uImage
$ make uImage
说明：截图中使用了4线程编译。
instruction：4 threads compilation is used in the screenshots。
complete compilation
target file
arch/arm/boot/uImage即为编译得到的目标文件，使用ls命令可查看文件信息。
arch/arm/boot/uImage is the target file through compilation，you can view the file information with ls command。
$ ls arch/arm/boot/uImage –la
编译模块(compile module)compile
$ make
说明：截图中使用了4线程编译。
instruction：4 threads compilation is used in the screenshots。
complete compilation
target file
编译完成后各模块的.ko文件位于代码所在的目录，通过find命令可以找出编译完成的模块，参考命令如下：
.ko file of each module is in the directory where code is located after compilation ，you can find the module compiled with find command after compilation,refering command as below：
$ find -name *.ko
Linux应用程序编译(Linux application compilation)
编写应用程序(write application)1) 创建应用程序目录
create application directory
$ mkdir ~/my-imx6/02_source/application/ -p
$ cd ~/my-imx6/02_source/application/
2) 编写应用程序（这里以hello.c为例）
write application（here take hello.c as example
创建 hello.c 文件写入以下代码并保存：
create hello.c and write following code and save：
int main(int argc, char **argv)
{
printf("Hello, MYZR!n");
return;
}
3) 查看代码
view code
$ cat hello.c

$ ${CROSS_COMPILE}gcc –v
提示：执行命令后可以看到终端显示出交叉编译工具的版本信息。如下图：
tips：you can see version information of cross compiler tool shown on terminal after execution of command.as below：
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
可以看到目标文件 hello.out 的属性。
you can get the property of target file hello.out。
文件系统(file system)
文件系统说明(file system instruction)文件系统包位于网盘对应的镜像文件夹中。支持的文件系统类型及下载方式可参照《MY-IMX6 烧录指导》。
file system package is located in 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》。
解压文件系统到编译主机(decompress file system to compiler host)1）创建文件系统的目录并进入
create directory of file system and enter
$ mkdir ~/my-imx6/04_rootfs/ -p
$ cd ~/my-imx6/04_rootfs/
2）将文件系统复制到~/my-imx6/04_rootfs/目录
copy file system to ~/my-imx6/04_rootfs/directory
这一步骤自己采取相应的方式进行
this step ***ould be done in your own way
3）解压文件系统到指定目录
decompress file system to specified directory
$ mkdir rootfs
$ sudo tar jxf rootfs-linux.tar.bz2 -C rootfs
添加应用到文件系统(add application to file system)$ cp ~/my-imx6/02_source/application/hello.out rootfs/app_test/
5）重新打包文件系统
re-pakcage file system
$ rm -rf rootfs-linux.tar.bz2
$ cd rootfs/
$ sudo tar cjf ../rootfs-linux.tar.bz2 *
添加模块到文件系统(add module to file system)准备需要模块的.ko文件，其它请参照“添加应用到文件系统”。
prepare .ko file of module needed,as to other operations please refer to“add application to file system”。
