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

USE_CETOOLS_IF_EXISTS

XDAIS_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

  File

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。
