在不断地增加。优秀的示波器产品除了具备高采样率、高带宽、高捕获率等特性，
良好的显示界面和用户体验也成为重要决定的因素，另外，还需要兼容更多的外
围通讯接口，以增强自身的扩展性和数据共享能力。目前，传统的国产示波器大
多采用DSP 作为处理器，这样做可以具有很高的运行速度，在数据实时处理方面

Put a condensed acronym table here. That is one that addresses acronyms that this Chapter uses. This means you should add/remove from the Table below.
The following acronyms are used throughout this chapter.
Texas Instruments Code Composer Studio
Texas Instruments Chip Support Library
Double Data Rate
Dynamic Host Configuration Protocol
Digital Signal Processor
Enhanced Direct Memory Access
Texas Instruments Inter-Processor Communication Development Kit
Joint Test Action Group
Texas Instruments Multi-Core Software Development Kit
Texas Instruments Programmers Development Kit
Eclipse Real-Time Software Components
Texas Instruments
Universal Asynchronous Receiver/Transmitter
Universal Serial Bus
We use the abbreviation TMS when referring to a specific TI device (processor) and the abbreviation TMD when referring to a specific platform that the processor is on. For example, TMS320C6740 refers to the C6740 DSP processor and TMDSEVML138 refers to the actual hardware EVM that the processor is on.
           CCS latest version can be installed. For the details refer the following link
CCS  comes with the different tools as BIOS/CGT etc.
For example - CCSv5 - Version: 5.3.0.0;  comes with bios_6_34_02_18 , xdctools_3_24_05_48
and C6000 Code Generation Tools 6.1.13
Untar the arago toolchain for ARMv5te (ARM9) (link to it is in the MCSDK release notes) to a Linux host PC. Add {tool chain install location}/arago-2011.09/armv5te/bin to the exported environment variable 'PATH'. ( refer Getting started Guide for downloading the toolchain)
For Installing the MCSDK refer the Getting started Guide
This section describes how to boot up U-Boot using CCS and is useful when the U-Boot image is not programmed on the SPI NOR flash.
             This section describes how to load the U-boot on EVM.        
refer the link :
The U-Boot comes with a set of default environment variables. Using those variables simplify several ways to boot kernel. Use the following command to set the default environment variables:
&env default -f –a
U-Boot supports three ways to boot kernel and is configured through 'boot' env variable. For each of this method, the boot env variable value to be used is provided in parenthesis.
tftp kernel and initrd ramfs (ramfs);
tftp kernel and use nfs mounted filesystem (net);
using ubifs (ubi);
You would need to add a few more variable specific to you setup:
serverip - IP address of your tftp server
tftp_root - Relative path from tftp server root directory where the image files are stored
boot - one of three ways to boot kernel (ramfs, net, ubi)
nfs_root - root directory exported by the NFS server (where the rootfs tar file was untarred)
Other defaults may be changed as needed. By default, these are set to use the image names from the Release. However for Preempt RT Full images, change the following env variables (applicable only for tftp boot of Linux and DTB):-
&setenv name_kern
&setenv name_fdt
Once u-boot is flashed to NAND ,change the switch settings to boot from NAND , for details of switch settings refer
Once switch settings are proper and EVM is powered up, once can see the u-boot prompt at Tera term/Hyperterminal on windows and Minicom/serial port on Linux
Mount the NFS file system and use the same for booting. You can use tftp server to load kernel, device tree and boot monitor. So, you would need to set the same “serverip” variable as described below. In addition to them set the “nfs_root” environment variable, which should refer to root directory of your target file system. The default environment variables assume that the target file system is on the same server as tftp server.
When the EVM is connected to linux host machine, you can use the scripts provided with the mcsdk release to make the u-boot environment up.
This is set-up as part of setup.sh script . The u-boot specific script is mcsdk_&version&/bin/setup-uboot-env.sh
Once this script is run successfuly u-boot environment will be set fine
When the EVM is connected to windows host machine, tftp server is running on windows/linux, nfs server is running on linux, following commands will help to boot the evm.  Copy the built kernel image to windows system and share this folder at tftp server, and set this windows system ip as server ip on the target
&setenv serverip 192.168.1.10
&setenv bootfile uImage-omapl138-lcdk.bin
&setenv bootargs 'mem=56M console=ttyS2, root=/dev/nfs nfsroot=$nfs_serverip:filesystem_full_path,nolock ip=dhcp'
&bootcmd 'bootm'
( sample bootargs after placing all the variable values
setenv bootargs 'mem=56M console=ttyS2, root=/dev/nfs
nfsroot=172.24.191.34:/home/x0089162/MCSDK/05-09-2013/filesystem/tisdk-rootfs-image-omapl138-lcdk,nolock ip=dhcp' )
Note :  if you don't already have NFS server setup on your Ubuntu PC, please see 
Once booting completes, you can login to the EVM as 'root' with no password
A sample log is shown below for reference
