准备开发环境(prepare development environment)

更新主机的源列表(update source list of host)$ sudo apt-get update

更新完成后如下图所示：
it looks like below after the update

安装aptitude包管理工具和ia32-libs(install management tool of aptitude package 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 compilation host is 32bit,then you can skip this step
安装aptitude包管理工具(install management tool of aptitude package)$ sudo apt-get -y install aptitude

提示：上图为安装过aptitude后，再次执行安装命令的截图。
tips: the above image is the screenshots after re-execution of installation command when intallation of aptitude was completed

tips: the above image is the screenshots after re-execution of installation command when intallation of ncurses-dev was completed
安装配置交叉编译工具链(install and configure cross compiler tool chain)

安装Linux交叉编译工具链(install cross compilation tool chain)1）进入交叉编译工具链目录
enter cross compilation tool chain diretory
$ cd ~/my-imx28/03_tools/
2）复制Linux交叉编译工具到目录
copy Linux cross compilation tool to directory
将gcc-4.4.4-glibc-2.11.1-multilib-1.0.tar.bz2复制到“~/my-imx28/03_tools”，这一步自己采取相应的方式完成。
copy gcc-4.4.4-glibc-2.11.1-multilib-1.0.tar.bz2 to“~/my-imx28/03_tools”,this step should be done in your own way
3）解压Linux交叉编译工具
decompress Linux cross compilation tool
$ tar jxf gcc-4.4.4-glibc-2.11.1-multilib-1.0.tar.bz2

4）复制交叉编译工具配置文件
copy congigured file of cross compilation tool
将gcc-4.4.4-glibc-2.11.1-multilib-env复制到“~/my-imx28/03_tools”，这一步自己采取相应的方式完成。
copy gcc-4.4.4-glibc-2.11.1-multilib-env to“~/my-imx28/03_tools”,this step should be done in your own way
5）检查安装
check installation
$ source gcc-4.4.4-glibc-2.11.1-multilib-env
$ ${CROSS_COMPILE}gcc –v

U-Boot编译(U-Boot compilation)

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“u-boot源码”复制到Linux开发主机的“~/my-imx28/02_source”。
copy“u-boot source code”downloaded to “~/my-imx28/02_source”of Linux development host
这一步自己采取相应的方式完成。
this step should be done in your own way
解压u-boot源码包(decompress u-boot source code)$ cd ~/my-imx28/02_source/
$ tar jxf u-boot-2009.08.tar.bz2
$ tar jxf imx-bootlets-src-10.12.01.tar.bz2

编译(compile)使编译配置文件生效(validate configured file of compilation)$ source ~/my-imx28/03_tools/gcc-4.4.4-glibc-2.11.1-multilib-env

进入u-boot源码目录(enter u-boot source code directory)$ cd ~/my-imx28/02_source/u-boot-2009.08

清除u-boot临时文件(remove u-boot temporary file)$ make distclean

配置u-boot(configure)

评估板主型号 (evaluation board main model)	CPU类型-内存容量 (CPU type--momery capacity)	对应的u-boot配置 (corresponding configuration of u-boot)
MY-IMX28-EVK	MX283/7, 128M	mx28_evk_config

MY-IMX28-EVK配置示例：

example for configuration of MY-IMX28-EVK
$ make mx28_evk_config

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imx28_ivt_uboot.***

compile imx28_ivt_uboot.***
提示：imx28_ivt_uboot.***是烧写的镜像。
tips: imx28_ivt_uboot.*** is the image programmed
$ cp u-boot ../imx-bootlets-src-10.12.01
$ cd ../imx-bootlets-src-10.12.01/
$ sudo cp elfto*** /usr/bin/
$ ./build

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imx28_ivt_uboot.***
you can get the compiled file imx28_ivt_uboot.*** with ls command after compilation.
$ ls

$ tar jxf linux-2.6.35.3.tar.bz2

内核编译配置(configuration of kernel compilation)使编译配置文件生效(validate configured file of compilation)$ source ~/my-imx28/03_tools/gcc-4.4.4-glibc-2.11.1-multilib-env

清除内核临时文件(remove kernel temporary file)

enter Linux source code directory
$ cd ~/my-imx28/02_source/linux-2.6.35.3

清除临时文件

remove temporary file
$ make distclean

内核配置(kernel configuration)$ cp .mx28_config .config

编译内核(compile kernel)

执行编译

execute compilation
$ make zImage -j4

编译完成

complete compilation

目标文件

target file
arch/arm/boot/uImage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/uImage is the kernel file compiled，you can check the file information with ls command
$ ls arch/arm/boot/uImage -la

编译模块 (compile module)

编译模块命令

command of module compilation
$ make modules

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

打包模块文件

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

应用程序编译(compile application)

Linux应用程序编译(compilation of Linux application)编写应用程序 (write application)

enter working directory
$ cd ~/my-imx28/01_application/

编写源代码

write source code
$ vim hello.c
写入以下代码并保存
write and save the following code

include

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

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 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
文件系统(file system)

文件系统rootfs.tar.bz2(file system rootfs.tar.bz2)用以下的方式增加自己的应用：（把MY-IMX28_Born_ToolProfilesMX28 Linux UpdateOS Firmwarefilesimage-linux-2635/rootfs.tar.bz2复制到“~/my-imx28/04_image/”目录下）。
add your own application in following ways:（ copy MY-IMX28_Born_ToolProfilesMX28 Linux UpdateOS Firmwarefilesimage-linux-2635/rootfs.tar.bz2 to the directory of “~/my-imx28/04_image/”）

文件系统rootfs.ubifs(file system rootfs.ubifs)复制mkfs.ubifs，ubinize到电脑的“/usr/bin”目录下（如果电脑有这两个应用就不需要复制了）；复制build_rootfs和ubinize.cfg到“~/my-imx28/04_image/”目录。
copy mkfs.ubifs，ubinize to“/usr/bin”directory of computer（copy is not needed if the computer has these two applications）；copy build_rootfs和ubinize.cfg to“~/my-imx28/04_image/”directory

烧写方式(way of programming)

至此，我们在“~/my-imx28/02_source/”得到了除文件系统以外的一套烧录文件。包括“imx28_ivt_uboot.***”、“uImage”、“rootfs.tar.bz2”。
so far，we get a set of programming files except file system from“~/my-imx28/02_source/”,including“imx28_ivt_uboot.***”、“uImage”、“rootfs.tar.bz2”
使用MFGTOOL烧写(program with MFGTOOL)把文件“imx28_ivt_uboot.***”、“uImage”、“rootfs.tar.bz2复制到“MY-IMX28_Born_ToolProfilesMX28 Linux UpdateOS Firmwarefilesimage-linux-2635”目录下。按住REC按键，插上MINI USB线和电源线，接着打开MfgTool.exe,点击“扫描设备”，检测到HID设备时，松开REC按键,如下所示：
copy “imx28_ivt_uboot.***”、“uImage”、“rootfs.tar.bz2 to the directory of “MY-IMX28_Born_ToolProfilesMX28 Linux UpdateOS Firmwarefilesimage-linux-2635”。hold REC key,plug in MINI USB line and power line,then open MfgTool.exe,click"scan device",release REC key when HID device is detected,as below:

点击菜单的“Options”，然后在选项“Profiles”选择“MY-IMX28-2.6.35 NAND with uboot”，接着点击“确定”，最后点击“开始”。
click"Options" in the menu,select “MY-IMX28-2.6.35 NAND with uboot”in the option “Profiles”,then click"Enter",finally click"start"

烧写成功后，点击“停止”就OK了。
when programming is succeeded,click"stop",to finish
注意：如果你用的文件系统是rootfs-qt.tar.bz2，请选择“QT-MY-IMX28-2.6.35 NAND with uboot”烧写镜像。
note: if the file system you are using is rootfs-qt.tar.bz2,please choose “QT-MY-IMX28-2.6.35 NAND with uboot”as programming image
