Error in porting DVSDK onto Devkit8000. Error his "insmod: cannot insert 'dsplinkk.ko': unknown symbol in module, or unknown parameter"

Hello Sanjeev Premi, let me explain the procedure i followed in breif.

We have purchased DEVKIT8000 borad from TIMLL, which use Omap3530 processor. They have just a provided DVSDK Demo version which has precomplied files in it.

We thought of porting TI DVSDK onto Devkit8000, so that we can use encoders. To port TI DVSDK onto Devkit8000, we need to generate MLO, u-boot.bin, and uImage for DEVKIT8000. When i searched how to generate and i got some patch files for Devkit8000, which has 2 patch files in it one to generate uboot.bin and another to generate uImage

http://code.google.com/p/devkit8000-unofficial-patches/downloads/list

Uboot patch file was for DVSDK-3.01 and uImage patch file was for DVSDK-3.00.

In DVSDK-3.00 there was no configuration file only for Devkit 8000 so again i downloaded DVSDK-3.01 and extracted the u-boot source code which has configuration file for devkit8000 and used it. I just used the MLO file which i got in DVSDK Demo version only

Steps i used to Rebuilt U-boot(from DVSDK 3.00)
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm devkit8000_config
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm
u-boot.bin was generated without any errors.

Steps i used to Rebuilt the Linux Kernel(from DVSDK 3.01)
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm omap3_devkit8000_defconfig
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm menuconfig
host $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm uImage modules
uImage was generated successfully without any errors.

Then steps i used to Rebuilt the DVSDK software for the target(from DVSDK 3.01)
host $ cd /home/<useracct>/dvsdk/dvsdk_3_00_02_44
host $ make check
host $ make info
host $ make clean
host $ make all

All files were generated without error.

Then copied MLO, u-boot.bin and uImage to one partition of the memory card and nfs to another partition of the memory card, Then finally i did
host $ make install.
It replaced some files in the memory card as follows

Question1: How to solve this DSP Link error?
Question2: In latest DVSDK i.e 4.01 version, there is no configuration file provided for Devkit8000 to generate uImage.
Question3: Is there any precompiled images for Devkit 8000 so that i can just use it for booting?
