For OMAP EVM Rev G with 256MB TI forgot to update the tcf file and stayed with the old one for 128MB.
It took me few days to find it since I didn't got any answer in this forum :-( ....

在DVEVM上，内存是256M，所以Codec中的例程都是按照256M内存进行配置的。而在，其他一些具体应用中，目标板的内存不一定为256M。所以，内存配置是Davinci开发板上一项重要的技术。解决：
1.先把内存调为128M
setenv bootargs mem=128M console=ttyS0,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait
savenv
2.更改loadmodules.sh
把
# 0x80000000 99 MB Linux
# 0x86300000 16 MB CMEM
# 0x87300000 13 MB CODEC SERVER
# Allocate 16MBB for CMEM
insmod cmemk.ko phys_start=0x86300000 phys_end=0x87300000 pools=1x5250000,1x1429
改为
# 0x80000000 128 MB Linux
# 0x86300000 16 MB CMEM
# 0x87300000 13 MB CODEC SERVER
# Allocate 16MBB for CMEM
insmod cmemk.ko phys_start=0x88000000 phys_end=0x89000000 pools=1x5250000,1x1429
3. ./loadmodules.sh

下载网址：
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_3_00/3_00_02_44/index_FDS.html
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
