九鼎创展s5p4418开发板-Android4.4-内核编译脚本分析

内核的编译脚本如下：

build_kernel()

{

         #Compiler kernel

         cd${BS_DIR_KERNEL} || return 1            //进入内核目录

         make${BS_CONFIG_KERNEL} ARCH=arm CROSS_COMPILE=${BS_CROSS_TOOLCHAIN_KERNEL} ||return 1    //配置内核

         make-j${threads} ARCH=arm CROSS_COMPILE=${BS_CROSS_TOOLCHAIN_KERNEL} uImage ||return 1           //编译内核

 

         #Copy uImage to release directory

         cp-v ${BS_DIR_KERNEL}/arch/arm/boot/uImage ${BS_DIR_RELEASE}    //将生成的内核镜像uImage拷到out/release 目录

 

         echo"^_^ kernel path: ${BS_DIR_RELEASE}/uImage"             //打印成功信息

        

         #generate boot.img

         cd${BS_DIR_TOP} || return 1                   //回到根目录

         echo'boot.img ->' ${BS_DIR_RELEASE}

         #Make boot.img with ext4 format, 64MB

         cp-v ${BS_DIR_RELEASE}/uImage ${BS_DIR_TARGET
