3.      安装
1.      安装TI DVSDK：dvsdk_setuplinux_3_00_02_44.bin
目录：/omap3530/dvsdk
安装之后会生成dvsdk_3_00_02_24文件夹，下面包含很多文件夹，包含几乎整个davinci架构的代码。

2.      安装其他组件
bios_setuplinux_5_33_06.bin
cs1omap3530_setuplinux_1_00_01-44.bin
xdctools_setuplinux_3_15_01_59.bin
OMAP35x-PSP-SDK-setuplinux-02.01.03.11.bin
目录：/omap3530/dvsdk/dvsdk_3_00_02_24

3.      安装Linux下DSP的交叉编译工具链: TI-C6x-CGT-v6.0.16.1.bin
目录：/omap3530/TI/

4.      安装ARM交叉编译工具链：arm-2008q1-126-arm-none-linux-gnueabi.bin
目录：/omap3530/CodeSourcery/arm-2008q1
并设置环境变量：
export PATH=/omap3530/CodeSourcery/arm-2008q1:$PATH
（如果想要每次开机启动环境变量都生效，请将上句加入/etc/profile文件的末尾）
4.      配置
1.      /omap3530/dvsdk/ dvsdk_3_00_02_44/Rule.make
将其中的变量路径按实际安装情况修改，例如：
# Define target platform.
PLATFORM=omap3530

# The installation directory of the DVSDK.
DVSDK_INSTALL_DIR=/omap3530/dvsdk/dvsdk_3_00_02_44

# For backwards compatibility
DVEVM_INSTALL_DIR=$(DVSDK_INSTALL_DIR)

# Where DSP/BIOS is installed.
BIOS_INSTALL_DIR=$(DVSDK_INSTALL_DIR)/bios_5_33_00_06

2．/omap3530/dvsdk/dvsdk_3_01_00_04/codec_engine_2_25_00_01/examples/xdcpath.mak
1)        设置平台、系统和程序类型
DEVICES  := OMAP3530
GPPOS := LINUX_GCC
PROGRAMS := APP_CLIENT DSP_SERVER

2)        设置变量安装路径
# (Mandatory) Specify where various components are installed.
CE_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/codec_engine_2_24
XDC_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/xdctools_3_15_01_59
BIOS_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/bios_5_33_06
DSPLINK_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/dsplink_1_61_03/packages

USE_CETOOLS_IF_EXISTS := 1
XDAIS_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/xdais_6_24
FC_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/framework_components_2_24
CMEM_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/linuxutils_2_24_02

WINCEUTILS_INSTALL_DIR:=
/omap3530/dvsdk/dvsdk_3_00_02_44/winceutils_1_00
BIOSUTILS_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/biosutils_1_01_00
EDMA3_LLD_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/edma3_lld_01_10_00_01
LPM_INSTALL_DIR :=
/omap3530/dvsdk/dvsdk_3_00_02_44/local_power_manager_1_24

CGTOOLS_V5T := /omap3530/CodeSourcery/arm-2008q1
CC_V5T := bin/arm-none-linux-gnueabi-gcc
CGTARGET := gnu.targets.arm.GCArmv5T

CGTOOLS_C64P := /omap3530/dvsdk/TI/cg6x_6_0_16
#CC_C64P      := bin/cl6x

在文件末尾加上XDC_PATH的补充，否则编译会报错！！！
# XDC_PATH is complete. Any other components you could add as
XDC_PATH := $(XDC_PATH);$(LPM_INSTALL_DIR)/packages
(can't locate the package 'ti.bios.power' along the path:...)

5.      编译
1.        进入目录CE例程目录
#cd /omap3530/dvsdk/dvsdk_3_00_02_44/codec_engine_2_24/examples/ti/sdo/ce/examples/
可以看到主要的关键的三个目录，apps,codecs,servers，分别放着应用程序代码，算法代码，算法服务器代码。

2.        编译server，选择all_codecs
#cd servers/all_codecs
#make clean
#make
编译完后会在bin/ti_platforms_evm3530/ 下生成来两个.x64P程序:
all_pm.x64P  all.x64P。
（如果编译出错，大多数是前面配置Rule.make,和xdcpaht.mak出错，可以根据错误提示更改过来）

3.        编译应用app，选择video_copy
#cd apps/video_copy
#make clean
#make   
编译完后会在在bin/ti_platforms_evm3530/ 下生成来一个.xv5T程序：
app_remote.xv5T
这是应用在arm端，算法在dsp端的程序。

6.      执行
1.        将下列文件拷贝到开发板同一目录下，例如/home/root
算法服务器：all.64P
应用程序：app_remote.xv5T
内核驱动：cmemk.ko, dsplinkk.ko, lpm_omap3530.ko
内核加载脚本：loadmodules.sh unloadmodules.sh

2.        加载内核驱动
#./ loadmodules.sh
CMEMK module: built on Apr 21 2010 at 00:22:22
Reference Linux version 2.6.29
File /omap3530/dvsdk/dvsdk_3_00_02_44/linuxutils_2_24_02/packages/ti/sdo/linux

DSPLINK Module (1.61.03) created on Date: Apr 21 2010 Time: 03:48:32
如果出错，可能是驱动版本和当前内核版本不匹配，需要重新编译驱动，并重新编译server和app。

3.        执行应用程序
