安装文件 ezsdk_dm816x-evm_5_05_02_00_setuplinux
DM8168-EZSDK文件结构如图所示。
（图片来自： http://processors.wiki.ti.com/index.php/EZSDK_Directory_Structure） 运行ezsdk/setup.sh，继续安装配置： 安装配置工具软件包（tftp服务器，nfs服务器，minicom串口工具，uboot和内核编译工具） 可参考： http://www.61ic.com/Article/DaVinci/TMS320DM81x/201112/39896.html
编译SDK，安装编译后组件在$HOME/tarfetfs目录下。
默认安装情况下： 1.在主机用tftp来引导linux内核，linux内核默认在/tftpboot目录下提取； 2.在主机用nfs来引导linux文件系统，文件系统默认安装在$HOME/targetfs目录下； 3.Minicom设置成和USB-UART（J6）通信。

-------------------------------------------------------------------------------- This step will extract the target filesystem to/home/eagle/targetfs #根文件系统的路径：/home/eagle/targetfs Note! This command requires you to have administratorpriviliges (sudo access) on your host. Press return to continue /home/eagle/targetfs already exists (r) rename existing filesystem (o) overwrite existingfilesystem (s) skip filesystem extraction [r] o Old /home/eagle/targetfs removed
Successfully extracted ezsdk-dm816x-evm-rootfs.tar.gz to/home/eagle/targetfs --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- This step will update the EXEC_DIR variables in the Rules.make file This will facilitate the SDK to install (with make install)rebuilt binaries in /home/eagle/targetfs/home/root/dm816x-evm
The files will be available from /home/root/dm816x-evm on thetarget.
This setting can be changed later by editing Rules.make andchanging the EXEC_DIR variable.
Press return to continueRules.make edited successfully.. --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- This step will export your target filesystem for NFSaccess.

-------------------------------------------------------------------------------- This step will set up minicom (serial communicationapplication) for SDK development
For boards that contain a USB-to-Serial converter on the board(BeagleBone), the port used for minicom will be automatically detected. Bydefault Ubuntu will not recognize this device. Setup will add will add a udevrule to /etc/udev/ so that from now on it will be recognized as soonas the board is plugged in.
For other boards, the serial will defualt to /dev/ttyS0.Please update based on your setup. --------------------------------------------------------------------------------
NOTE: For boards with a built-in USB to Serial adapter pleasepress ENTERat the prompt below. The correct port will bedetermined automatically at a later step. For all otherboards select theserial port that the board is connected to Which serial port do you want to use with minicom? [ /dev/ttyS0]
Configuration saved to /home/eagle/.minirc.dfl. You can changeit further from inside minicom, see the Software Development Guide for moreinformation. --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- This step will set up the u-boot variables for booting theEVM. Autodetected the following ip address of your host, correct itif necessary [ ]
Select Linux kernel location: 1: TFTP 2: SD card

Select root file system location: 1: NFS 2: SD card

-------------------------------------------------------------------------------- Would you like to create a minicom script with the aboveparameters (y/n)? [ y ]
Successfully wrote setup_uimage-tftp_fs-nfs.minicom
Would you like to run the setup script now (y/n)? Thisrequires you to connect the RS-232 cable between your host and EVM as well as yourethernet cable as described in the Quick Start Guide. Please ensure that SW4switch for NAND is in ON position.
Once answering 'y' on the prompt below you will have 300seconds to connect the board and power cycle it before the setup times out
After successfully executing this script, your EVM will be setup. You will be able to connect to it by executing 'minicom -w' or if youprefer a windows host you can set up Tera Term as explained in the SoftwareDeveloper's Guide. If you connect minicom or Tera Term and power cycle the boardLinux will boot.
