    下载编译linux源码

    (默认是zero-4.10.y分支):

    ~~ {.sourceCode .bash}
    git clone https://github.com/Lichee-Pi/linux.git
    cd linux
    make ARCH=arm licheepi_zero_defconfig
    make ARCH=arm menuconfig #add bluethooth, etc.
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules_install
    ~
    ~

    编译完成后,zImage在arch/arm/boot/下,驱动模块在out/下
