编译U-boot和内核

前奏准备：

1.安装apt $ apt-get install openjdk-6-jdk

2.安装git $apt-get install git

3.$git init

安装marvell交叉编译gcc，设置环境变量

4.$ export PATH=/opt/arm-marvell-linux-gnueabi/bin:$PATH
$ export CROSS_COMPILE=arm-marvell-linux-gnueabi-
5.$ cd gplugd-uboot
$ make distclean
$ make gplugd_config
$ make all

6.$ ls u-boot*
u-boot
u-boot.bin
u-boot.map
u-boot.srec
where
• u-boot.bin is a raw binary image file
• u-boot is an image file in ELF binary format
• u-boot.srec is an image file in Motorola S-Record format

内核编译：

$ cd gplugd-linux-2.6

$ export PATH=/opt/arm-marvell-linux-gnueabi/bin:$PATH
$ export CROSS_COMPILE=arm-marvell-linux-gnueabi-

$ export ARCH=arm

Use the following commands to clean, configure, and build the Linux kernel:
$ make mrproper
$ make gplugd_defconfig
$ make all
To let make display more detailed messages during the build, add the “V=1” option to the make command as shown
below:
$ make V=1 all

If the build is successful, the resulting kernel image file, zImage, will be in arch/arm/boot subdirectory in the source file
tree:
$ ls arch/arm/boot/zImage
arch/arm/boot/zImage
