【1】sd 卡分区： ti提供了自己的分区shell脚本create-sdcard.sh 脚本目录在：ti-sdk-am335x-evm-05.06.00.00/bin/
（1）插入sd卡（若是笔记本sd卡槽，不显示sd卡，可能是因为sd卡走的是PCI总线而不是usb，这时需要一个读卡器）
（2）执行sudo ./create-sdcard.sh
（3）弹出以下信息。按如下标示进行分区即可（红色为自己填写信息），此处分区分了两个，一个boot，一个rootfs ################################################################################
This script will create a bootable SD card from custom or pre-built binaries.
The script must be run with root permissions and from the bin directory of the SDK
Example: $ sudo ./create-sdcard.sh
Formatting can be skipped if the SD card is already formatted and partitioned properly.

################################################################################
Select 2 partitions if only need boot and rootfs (most users) Select 3 partitions if need SDK & CCS on SD card. This is usually used by device manufacturers with access to partition tarballs.

boot和rootfs分区自动挂载到/media/
【2】环境搭建，生成bootloader和编译内核
ti提供的资料中会有一个叫ti-sdk-am335x-evm-05.04.01.00-Linux-x86-Install文件，这个里面有必要的工具包（minicom，filesystem，nfs，tftp，uboot，load uboot script）
打开终端：
（1）./ti-sdk-am335x-evm-05.04.01.00-Linux-x86-Install 将会在主目录下生成名为ti-sdk-am335x-evm-05.04.01.00 cd ti-sdk-am335x-evm-05.04.01.00/ sudo ./setup.sh(注意：系统不是10.04，则vim /ti-sdk-am335x-evm-05.04.01.00/setup.sh,将第十四行用#屏蔽掉。#$cwd/bin/setup-host-check.sh)。 遇到选项回车默认即可。
（2）gedit ~/.bashrc 在打开的文件末尾添加如下：
export PATH=/home/share/ti-sdk-am335x-evm-05.04.01.00/linux-devkit/bin:$PATH
export ARCH=arm
export CROSS_COMPILE=arm-arago-linux-gnueabi-
保存退出 source ~/.bashrc(使其生效)
（3）编译u-boot cd ti-sdk-am335x-evm-05.04.01.00/board-support/u-boot-2011.09-psp04.06.00.07/ make o=am335x am335x_evm 在am335x中会生成第一级bootloader MLO和第二级bootloader u-boot.img
（4）编译内核 cd ti-sdk-am335x-evm-05.04.01.00/board-support/linux-3.2-psp04.06.00.07.sdk/
依次执行如下命令：
make mrproper
make tisk_am335x-evm_defconfig
make （生成uImage）
uImage 在arch/arm/boot/下生成了uImage(内核)
（5） 将MLO，u-boot.img,uImage拷贝到SD卡的boot分区 将targetNFS里的所有文件拷贝到rootfs分区
将sd卡插入开发板上电。
