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-myimx6”，所以我们需要把zImage复制为zImage-myimx6。
Note: The kernel file name which is going to be programed and started is “zImage-myimx6”, So we should Copy zImage as zImage-myimx6
$ cp arch/arm/boot/zImage ~/my-imx6/04_image/image-linux-31452/zImage-myimx6

编译设备树(compife device tree)

评估板型号规格与设备树文件对应关系见下表：
The correspondence between the type of evaluation board and device tree is shown below：

评估板主型号 (development main model)	CPU类型-内存容量 (CPU type-memory capacity)	对应的设备树文件 (corresponding device tree file)
MY-IMX6-EK200	i.MX 6QuadPlus - 1G	myimx6ek200-6qp.dtb
	i.MX 6QuadPlus - 2G	myimx6ek200-6qp-2g.dtb
	i.MX6 Quad - 1G	myimx6ek200-6q.dtb
	i.MX6 Quad - 2G	myimx6ek200-6q-2g.dtb
	i.MX6 DualLite - 1G	myimx6ek200-6u.dtb
	i.MX 6Solo - 512M	myimx6ek200-6s.dtb
	i.MX 6Solo - 1G	myimx6ek200-6s-1g.dtb
MY-IMX6-EK314	i.MX 6QuadPlus - 1G	myimx6ek314-6qp.dtb
	i.MX 6QuadPlus - 2G	myimx6ek314-6qp-2g.dtb
	i.MX6 Quad - 1G	myimx6ek314-6q.dtb
	i.MX6 Quad - 2G	myimx6ek314-6q-2g.dtb
	i.MX6 DualLite - 1G	myimx6ek314-6u.dtb
MY-IMX6-EK336	i.MX 6QuadPlus - 1G	myimx6ek336-6qp.dtb
	i.MX 6QuadPlus - 2G	myimx6ek336-6qp-2g.dtb
	i.MX6 Quad - 1G	myimx6ek336-6q.dtb
	i.MX6 Quad - 2G	myimx6ek336-6q-2g.dtb
MY-IMX6-EK140	i.MX 6UltraLite-256M	myimx6ek140-6g.dtb
	i.MX 6UltraLite-512M	myimx6ek140-6g-512m.dtb
	i.MX 6UltraLite Full - 256M (2eth)	myimx6ek140p-6g.dtb
	i.MX 6UltraLite Full - 256M (8uart)	myimx6ek140p-6g-8uart.dtb
	i.MX 6UltraLite Full - 512M (2eth)	myimx6ek140p-6g-512m.dtb
	i.MX 6UltraLite Full - 512M (8uart)	myimx6ek140p-6g-512m-8uart.dtb

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-31452/

编译模块 (compife module)

编译模块命令

compile module command
$ make modules

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 *

Copy module package to image directory

评估板型号 (development board model)	目标模块包 (target module package)
MY-IMX6-EK200	kernel-modules-myimx6.tar.bz2
MY-IMX6-EK314
MY-IMX6-EK336
MY-IMX6-EK140	kernel-modules-myimx6g.tar.bz2

$ cp ../modules.tar.bz2 ~/my-imx6/04_image/image-linux-31452/kernel-modules-myimx6.tar.bz2
注意：如果是编译内核时配置文件使用的是 myimx6_defconfig，在这里要把 modules.tar.bz2 复制为 kernel-modules-myimx6.tar.bz2；如果是编译内核时配置文件使用的是 myimx6ul_defconfig，在这里要把 modules.tar.bz2 复制为 kernel-modules-myimx6g.tar.bz2
Note:when you compile the Kernel If the configuration file you use is myimx6_defconfig, here you should Copy modules.tar.bz2 as kernel-modules-myimx6.tar.bz2.If the configuration file is myimx6ul_defconfig，you should Copy modules.tar.bz2 as kernel-modules-myimx6g.tar.bz2.
