am335x的Kernel编译

1.清理内核命令

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- mrproper

(注意：此命令会删除.config文件)

或者

$cd
$make linux_clean

:此时为/home/qiuweibo/workspace/002.am335x/000.install/ti-sdk-am335x-evm-06.00.00.00

2.配置内核

2.1使用默认配置

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

  在arch/arm/configs查找

 Device                       SDK config                                      PSP config
AM335x/Beaglebone      tisdk_am335x-evm_defconfig           am335x_evm_defconfig
AM37x                         tisdk_am37x-evm_defconfig           omap3_evm_defconfig
AM3517                      tisdk_am3517-evm_defconfig           am3517_evm_defconfig
Beagleboard                tisdk_beagleboard_defconfig           omap3_beagle_defconfig
AM180x                     tisdk_am180x-evm_defconfig           da850_omapl138_defconfig

例如：

默认PSP配置

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_evm_defconfig

默认SDK配置

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig

2.2裁剪内核

可以使用menuconfig或xconfig两种命令配置

menuconfig: an ncurses based configuration utility xconfig: a Qt based graphical configuration utility.
NOTE
On some systems in order to use xconfig you may need to install the libqt3-mt-dev package. For example on Ubuntu
10.04 this can be done using the command sudo apt-get install libqt3-mt-dev

i例如：使用menuconfig命令
$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
使用xconfig命令
$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- xconfig

2.3编译内核

2.3.1编译内核文件

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage

文件生成在arch/arm/boot/下

2.3.2编译内核模块

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules

文件生成为.ko

2.4内核模块安装

$sudo make ARCH=arm INSTALL_MOD_PATH= modules_install

例如

For example if you are installing the modules to an NFS share located at /home/user/targetNFS you would do:
sudo make ARCH=arm INSTALL_MOD_PATH=/home/user/targetNFS modules_install
