[复制链接]
准备源码(prepare source code)准备源码包 (prepare source code package)1)创建工作目录
create working directory
创建 ~/my-rk3288 作为工作目录
create ~/my-rk3288 as working directory
$ mkdir ~/my-rk3288
创建 ~/my-rk3288/02_source 作为源码目录
create ~/my-rk3288/02_source as source code directory
$ mkdir ~/my-rk3288/02_source
创建 ~/my-rk3288/03_tools 作为工具目录
create ~/my-rk3288/03_tools as tool directory
$ mkdir ~/my-rk3288/03_tools
2)复制源码包到开发主机中
copy source code package to the development host
这一步骤自己采取相应的方式进行。
do it in this step in your own way。
提示:这里将网盘中“02_源码”复制到Linux开发主机的“~/my-rk3288/02_source”,将网盘中“03_工具”复制到Linux开发主机的“~/my-rk3288/03_tools”,将网盘中“01_应用”复制到Linux开发主机的“~/my-rk3288/01_application”。
tip:this step is to copy “02_source code”from network disk to “~/my-rk3288/02_source”in development host, copy “03_tool”to “~/my-rk3288/03_tools, and copy “01_application”to “~/my-rk3288/01_application”。in development host
解压源码包 (decompress source code package)1)解压u-boot源码和内核源码
decompress u-boot source code and kernel source code
$ cd ~/my-rk3288/02_source
$ tar jxf rk32-myzr_uboot_2014.10_201803028.tar.bz2
$ tar jxf rk32-myzr_kernel_3.10_201803028.tar.bz2
2)解压交叉编译工具
decompress cross compiler tool
$ cd ~/my-rk3288/03_tools/
$ tar jxf gcc-arm-eabi-4.6.tar.bz2
开发环境配置(development environment configuration)安装需要的包 (install package needed)1)更新源列表
list of updated source
$ sudo apt-get update
更新完成后如下图所示:
after update,it will look like below:
2)安装aptitude包管理工具和ia32-libs
install aptitude package management tool 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 compiler host is 32bit,you can skip this step。
install aptitude package management tool
$ sudo apt-get –y install aptitude
install ia32-libs with aptitude
$ sudo aptitude –y install ia32-libs
提示:下图为安装过aptitude和ia32-libs后,再次执行安装命令的截图。
tips:following is the screenshots with re-execution of installation command after installation of aptitude and ia32-libs is finished。
3)安装mkimage工具
install mkimage tool
$ sudo apt-get -y install uboot-mkimage
提示:下图为安装过mkimage工具后,再次执行安装命令的截图。
tips:following is the screenshots with re-execution of installation command after installation of mkimage tool is finished。
4)安装ncurses-dev
install ncurses-dev
说明:make menuconfig对其具有依赖性质。
instruction:make menuconfig is dependent on it。
$ sudo aptitude -y install ncurses-dev
提示:下图为安装过ncurses-dev工具后,再次执行安装命令的截图。
tips:following is the screenshots with re-execution of installation command after installation of ncurses-dev tool is finished。
编译u-boot(compile u-boot) 进入u-boot源码目录(enter u-boot source code directory)$ cd ~/my-rk3288/02_source/rk32-myzr_uboot_2014.10/
使配置文件生效(validate configured file)execute source command
$ source ~/my-rk3288/03_tools/gcc-arm-eabi-4.6-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:
评估板主型号
(evaluation board main model) | CPU类型-内存容量
(CPU type-memory capacity) | 对应的u-boot配置
(corresponding u-boot configuration) | MY-RK3288-EK314 | RK3288(四核)- 2G
(RK3288(quad. core)- 2G) | rk3288_defconfig |
MY-RK3288-EK314-2G configuration example:
$ make rk3288_defconfig
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编译过程大概需要十几秒钟的时间。
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RK3288UbootLoader_V2.30.10.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-rk3288/02_source/rk32-myzr_kernel_3.10/
使配置文件生效(validate configured file)execute source command
$ source ~/my-rk3288/03_tools/gcc-arm-eabi-4.6-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-RK3288-EK314系列评估板使用的配置文件是rk3288-myzr-linux_defconfig

说明:截图中使用了8线程编译。
instruction:8 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/zImage is the target file through compilation,you can view the file information with ls command。
$ ls arch/arm/boot/zImage -la
编译模块(compile module)compile
$ make modules
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
打包linux-boot.img(pack linux-boot.img) 编译rockchip-mkbootimg(compile rockchip-mkbootimg)1) 创建应用程序目录
