安裝檔案 ezsdk_dm816x-evm_5_05_02_00_setuplinux
DM8168-EZSDK檔案結構如圖所示。
（圖檔來自： http://processors.wiki.ti.com/index.php/EZSDK_Directory_Structure） 運作ezsdk/setup.sh，繼續安裝配置： 安裝配置工具軟體包（tftp伺服器，nfs伺服器，minicom序列槽工具，uboot和核心編譯工具） 可參考： http://www.61ic.com/Article/DaVinci/TMS320DM81x/201112/39896.html
編譯SDK，安裝編譯後元件在$HOME/tarfetfs目錄下。
預設安裝情況下： 1.在主機用tftp來引導linux核心，linux核心預設在/tftpboot目錄下提取； 2.在主機用nfs來引導linux檔案系統，檔案系統預設安裝在$HOME/targetfs目錄下； 3.Minicom設定成和USB-UART（J6）通信。

-------------------------------------------------------------------------------- TISDK setup script
This script will set up your development host for sdkdevelopment. Parts of this script require administrator priviliges (sudoaccess). --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- Verifying Linux host distribution Ubuntu 10.04 LTS found successfully, continuing.. --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- This step will make sure you have the proper host supportpackages installed using the following command: sudoapt-get install xinetd tftpd nfs-kernel-serverminicom build-essential libncurses5-devuboot-mkimage autoconf automake
Note! This command requires you to have administratorpriviliges (sudo access) on your host. Press return to continue

-------------------------------------------------------------------------------- In which directory do you want to install the targetfilesystem?(if this directory does not exist it will becreated) Ensure that complete path is provided, otherwise NFS path inbootargs might be incomplete [ /home/eagle/targetfs ] --------------------------------------------------------------------------------
-------------------------------------------------------------------------------- This step will extract the target filesystem to/home/eagle/targetfs #根檔案系統的路徑：/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.
Note! This command requires you to have administratorpriviliges (sudo access) on your host. Press return to continue

-------------------------------------------------------------------------------- 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
[ 1 ]
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.
