    Hi Srilakshmi

    You need to follow the procedure mentioned in the user guide DM816x_C6A816x_AM389x_VPSS_Video_Driver_User_Guide_PSP_04.00.00.xx.pdf present at /$HOME/board-support/docs.

    Please follow the section “Build Linux VPSS, Fbdev and V4L2 Display Drivers”

    make ARCH=arm CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabiti8168_evm_defconfig

    $ make ARCH=arm CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- uImage

    $ make ARCH=arm CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- menuconfig

    -

    -

    make ARCH=arm CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- modules

    Above steps will create the modules ti81xxvo.ko.Copy the module to file system after that you can insert the module.

     Thanks and regards
