使配置文件生效(validate configured file)
execute source command $ source ~/my-imx6/03_tools/myimx6_3035_build_env
view compiler configuration $ echo $ARCH $ echo $CROSS_COMPILE 提示:可看到ARCH和CROSS_COMPILE被设置 tips:you can see that ARCH和CROSS_COMPILE is configured
verify cross compiler tool configuration $${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: 清除u-boot配置(remove u-boot configuration) $ make distclean u-boot配置(u-boot configuration)
evaluation board and its corresponding u-boot compiler configuration:
MYIMX6EK200-6Qxx-1G configuration example: $ make myimx6ek200_6q_config 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/ 使配置文件生效(validate configured file)
execute source command $ source ~/my-imx6/03_tools/myimx6_3035_build_env
view compiler configuration $ echo $ARCH $ echo $CROSS_COMPILE 提示:可看到ARCH和CROSS_COMPILE被设置 tips:you can see that ARCH和CROSS_COMPILE is configured
verify cross compiler tool configuration $ ${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: 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 使编译配置文件生效(validate compiler configured file)
execute source command $ source ~/my-imx6/03_tools/myimx6_3035_build_env
view compiler configuration $ echo $ARCH $ echo $CROSS_COMPILE 提示:可看到ARCH和CROSS_COMPILE被设置 tips:you can see that ARCH和CROSS_COMPILE is configured
verify cross compiler tool configuration $ ${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”。 |
