2678 Linux 编译手册

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-imx6/02_source”。
copy“u-boot 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u-boot源码包(decompress u-boot source code package)

$ cd ~/my-imx6/02_source/
$ tar xf u-boot-2015.04.tar.xz

编译(compilation)使编译配置文件生效(validate compiler configuration file)

$ source ~/my-imx6/03_tools/gcc-linaro-arm-linux-gnueabihf-492-env

进入u-boot源码目录(enter u-boot source code directory)

$ cd ~/my-imx6/02_source/u-boot-2015.04

清除u-boot临时文件 (remove u-boot temporary files)

$ make distclean

配置u-boot(configure u-boot)

评估板及对应的 u-boot 编译配置：

MYIMX6EK200-6Q-1G配置示例：

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