英码SBC3730 DM3730linux内核的配置和编译

1、首先设置好环境变量，命令为：

 export PATH= /usr/local/arm/arm-2009q1/bin:$PATH 

查看环境变量命令为：

echo $PATH

输出编译器的路径

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/arm-2009q1/bin:/usr/local/arm/arm-2009q1/bin

可输入arm-none-linux-gnueabi-gcc -v，若能看到版本号则证明安装成功。

2、内核编译

进入内核压缩包所在的文件夹，解压源码包

sudo tar jxvf linux-03.00.01.06.tar.bz2 

cd linux-03.00.01.06进入源码目录

修改Makefile文件

export KBUILD_BUILDHOST := $(SUBARCH)ARCH?= armCROSS_COMPILE?=

清除原配置：

make ARCH=arm distclean

载入设置好的配置文件： 

make ARCH=arm omap3_stalker_defconfig

编译内核： 

输入命令make ARCH=arm出现下面错误

  CHK     include/linux/version.hmake[1]: `include/asm-arm/mach-types.h' is up to date.  CHK     include/linux/utsrelease.h  SYMLINK include/asm -> include/asm-arm  CC      kernel/bounds.scc1: error: unrecognized command line option "-mlittle-endian"cc1: error: unrecognized command line option "-mabi=aapcs-linux"cc1: error: unrecognized command line option "-mno-thumb-interwork"kernel/bounds.c:1: error: bad value (armv5t) for -march= switchkernel/bounds.c:1: error: bad value (armv5t) for -mtune= switchmake[1]: *** [kernel/bounds.s] Error 1make: *** [prepare0] Error 2

输入命令 make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm 出现下面错误

make: /usr/local/arm/arm-2009q1/bin/arm-none-linux-guneabi-gcc: Command not foundscripts/kconfig/conf -s arch/arm/Kconfigmake: /usr/local/arm/arm-2009q1/bin/arm-none-linux-guneabi-gcc: Command not found  CHK     include/linux/version.h  UPD     include/linux/version.h  Generating include/asm-arm/mach-types.h  CHK     include/linux/utsrelease.h  UPD     include/linux/utsrelease.h  SYMLINK include/asm -> include/asm-arm  CC      kernel/bounds.s/bin/sh: 1: /usr/local/arm/arm-2009q1/bin/arm-none-linux-guneabi-gcc: not foundmake[1]: *** [kernel/bounds.s] Error 127make: *** [prepare0] Error 2

最后使用命令make CROSS_COMPILE=arm-none-linux-gnueabi-编译成功

3、输出uImage文件

make CROSS_COMPILE=arm-none-linux-gnueabi- uImage

编译完成输出一下信息，uImage在源码目录的arch/arm/boot/里面
