  • MYIMX6EK200-6Q-1G配置示例:

MYIMX6EK200-6Q-1G configuration example:
$ make myimx6ek200-6q_defconfig

执行编译(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.

  • 编译完成

complete compilation
提示:u-boot编译过程大概需要一、两分钟时间。
Tips: u-boot compiling process may take one or two minutes。


目标文件(target file)
  • 编译文件

compile file
编译完成后通过ls命令即可看到编译得到的文件u-boot.imx
you can get the compiled file u-boot .imx with ls command after compilation.
$ ls

  • 目标文件

MY-IMX6系列评估板的u-boot配置对应的目标文件名见下表:

myimx6ek140p-6y-512m_defconfiguboot-myimx6ek140p-6y-512m.imx

我们需要将编译得到的u-boot.imx复制为我们的目标文件名。
We need to copy the compilied file u-boot.imx as our target file name.:
这里以MY-IMX6-EK200-6Q为例(把配置myimx6ek200-6q_defconfig编译生成的u-boot.imx复制为目标文件):
Copy the generated file u-boot.imx from the compilation of myimx6ek200-6q_defconfig as target file.):
$ cp u-boot.imx ~/my-imx6/04_image/image-linux-4115/uboot-myimx6ek200-6q.imx

编译内核(compile kernel)
准备编译(prepare compilation)复制源码包到开发主机中(copy source code package to development host)

将下载的“linux源码”复制到Linux开发主机的“~/my-imx6/02_source”。
copy “linux source code”downloaded to “~/my-imx6/02_source”of Linux development host。
这一步自己采取相应的方式完成。
complete this step by yourself in a proper way。


解压linux源码包(decompress linux source code package)

$ cd ~/my-imx6/02_source/
$ tar xf linux-4.1.15__svn189.tar.xz


内核编译配置(kernel compilation configuration)使编译配置文件生效(validate compilfer configuration file)

$ source ~/my-imx6/03_tools/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf-env


清除内核临时文件(remove kernel temporary file)
  • 进入linux源码目录

enter linux source code directory
$ cd ~/my-imx6/02_source/linux-4.1.15

  • 清除临时文件

remove temporary file
$ make distclean


内核配置(kernel configuration)
  • 内核配置文件

kernel configuration file

评估板型号
(evaluation board model)
配置文件
(configuration file)
MY-IMX6-EK200myimx6a9_defconfig
MY-IMX6-EK314
MY-IMX6-EK336
MY-IMX6-EK140myimx6a7_defconfig

$ make myimx6a9_defconfig
如果是编译 MY-IMX6-EK140 的内核,请使用 $ make myimx6a7_defconfig
if what compified is kernel of MY-IMX6-EK140,please use $ make myimx6a7_defconfig
这里以 myimx6a9_defconfig 为例。
take myimx6a9_defconfig as an example。


编译内核(compife kernel)
  • 执行编译

execute compilation
$ make zImage

  • 编译完成

complete compilation

  • 目标文件

target file
arch/arm/boot/zImage即为编译得到的内核文件,使用ls命令可查看文件信息。
arch/arm/boot/zImage is the kernel file compifed,you can check file information with ls command。
$ ls arch/arm/boot/zImage -la

注意:我们烧录及启动的内核文件名为“zImage-myimx6a9”或“zImage-myimx6a7”,所以我们需要把zImage复制为zImage-myimx6a9或zImage-myimx6a7。
Note: The kernel file name which is going to be programed and started is “zImage-myimx6” or “zImage-myimx6a7”, So we should copy zImage as zImage-myimx6a9 or zImage-myimx6a7
$ cp arch/arm/boot/zImage ~/my-imx6/04_image/image-linux-4115/zImage-myimx6a9 (A9)

$ cp arch/arm/boot/zImage ~/my-imx6/04_image/image-linux-4115/zImage-myimx6a7 (A7)

  • 以MY-IMX6-EK200-6Q-1G为例

take MY-IMX6-EK200-6Q-1G as example
$ make myimx6ek200-6q.dtb

  • 目标文件

target file
使用ls命令可查看编译得到的目标设备树文件信息:
You can browse the target device tree file information from compilation with ls command:
$ ls arch/arm/boot/dts/myimx6ek*.dtb

复制设备树文件到镜像目录
Copy device tree file to image directory
$ cp arch/arm/boot/dts/myimx6ek*.dtb ~/my-imx6/04_image/image-linux-4115/

编译模块 (compife module)
  • 编译模块命令

compile module command
$ make modules

  • 安装模块到指定目录

Install module to the specified directory
$ make modules_install INSTALL_MOD_PATH=./modules

  • 打包模块文件

package the module file
$ cd modules
$ tar cjf ../modules.tar.bz2 *

  • 复制模块包到镜像目录

Copy module package to image directory

评估板型号
(development board model)
目标模块包

$ cp ../modules.tar.bz2 ~/my-imx6/04_image/image-linux-4115/kernel-modules-myimx6a9.tar.bz2
注意:如果是编译内核时配置文件使用的是 myimx6a9_defconfig,在这里要把 modules.tar.bz2 复制为 kernel-modules-myimx6a9.tar.bz2;如果是编译内核时配置文件使用的是 myimx6a7_defconfig,在这里要把 modules.tar.bz2 复制为 kernel-modules-myimx6a7.tar.bz2
Note:when you compile the Kernel If the configuration file you use is myimx6a9_defconfig, here you should Copy modules.tar.bz2 as kernel-modules-myimx6a9.tar.bz2.If the configuration file is myimx6a7_defconfig,you should Copy modules.tar.bz2 as kernel-modules-myimx6a7.tar.bz2.


应用程序编译(application compilation)
Linux应用程序编译(Linux application compilation)编写应用程序(write an application)
  • 创建应用程序的源码目录和Linux-4.1.15的可执行程序目录

Create application source code directory and Linux-4.1.15 executable program directory
$ mkdir ~/my-demo/source_code -p

$ mkdir ~/my-demo/bin-l4115 -p

  • 编写源代码

write source code
$ cd ~/my-demo/source_code
$ vi hello.c

写入以下代码并保存
write following code and save
#include

int main(int argc, char **argv)
{
  printf("Hello, MYZR!n");

  return;
}

  • 查看代码

view code

$ cat hello.c

编译应用程序(compife application)
  • 配置环境变量

Configure environment variables
$ source ~/my-imx6/03_tools/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf-env

  • 编译

compife
$ ${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 command contains “$”,which is “${CROSS_COMPILE}gcc”. It is the environment variable generated when referring to our source.。

  • 目标文件

target file
$ file hello.out

可以看到目标文件 hello.out 的属性。
you can see the property of target file hello.out。


保存目标可执行文件(save target executable file)

$ mv hello.out ~/my-demo/bin-l31452/


应用程序打包(package application)说明(instruction)

烧录工具支持烧录“my-demo.tar.xz”的文件包到评估板。所以在这里我们把我们需要的应用程序打包为“my-demo.tar.xz”。至于“my-demo.tar.xz”会被烧录到哪个位置,请看《烧录手册》
Programming tool supports to program “my-demo.tar.xz” file package to evaluation board.So We package applications We need as “my-demo.tar.xz”.while where “my-demo.tar.xz” will be programmed ,refer to 《programming manual》


打包应用程序(package application)

1)打包
package
这里我们将整个my-demo目录打包。
Here We package the whole my-demo directory。
$ cd ~
$ tar cjf my-demo.tar.bz2 my-demo

2)复制应用程序包为目标烧录文件
Copy application package as target programming file
$ cp my-demo.tar.bz2 ~/my-imx6/04_image/image-linux-31452/


目标烧录文件(target programming file)

至此,我们在“~/my-imx6/04_image/image-linux-31452/”得到了除文件系统以外的一套烧录文件。包括“uboot*.imx”、“myimx6*.dtb”、“zImage-myimx6”、“kernel-modules.tar.bz2”、“my-demo.tar.bz2”。
So far,we get a set of programming file except file system from“~/my-imx6/04_image/image-linux-31452/”。including“uboot*.imx”、“myimx6*.dtb”、“zImage-myimx6”、“kernel-modules.tar.bz2”、“my-demo.tar.bz2”。
现在可以参照《烧录手册》烧录我们自己编译出来的image了。
Now we can program the image we compiled by ourselves referring to 《programming manual》.
