    In /dvr_rdk/mcfw/interfaces/link_api/system_debug.h is

    #define SYSTEM_USE_TILER define enabled ?

    If it is not enabled, comment out call to SystemTiler_enableAllocator & SystemTiler_disbleAllocator function in /dvr_rdk/mcfw/src_linux/mcfw_api/usecases/multich_vdec_vdis.c

    If it is enabled and you are still seeing the issue exception indicates memory corruption issue. Are you always facing the issue or only sometimes ?

    Hi Badri Narayanan,

    The SYSTEM_USE_TILER is enabled define. The system can be stop well after I comment out call to SystemTiler_enableAllocator & SystemTiler_disbleAllocator function.

    I always facing this issue before I comment out function call.

    Thanks,

    Hi Badri Narayanan,

    The root cause of this issue is 814x don't support tiler enable? I still don't know the root cause.

    Thanks,

    Can you share multich_vdec_vdis.c in your codebase. Tiler enable is supported in 814x

    Hi Badri Narayanan,

    This issue can be reproduced at original rdk 3.0 source code, can you not reproduce? This issue happen at 8148 build, not 816x build.

    Thanks,

    Jacson

    Can you try modifying multich_vdec_vdis.c as below:

    #if (tilerEnable == FALSE)
        {
            /* Disable tiler allocator for this usecase
             * for that tiler memory can be reused for
             * non-tiled allocation
             */
            SystemTiler_enableAllocator();
        }
    #endif

    to

    if (tilerEnable == FALSE)
        {
            /* Disable tiler allocator for this usecase
             * for that tiler memory can be reused for
             * non-tiled allocation
             */
            SystemTiler_enableAllocator();
        }

    This should be done both for enable allocator and disable allocator.

    You will have to declare Bool tilerEnable in  MultiCh_deleteVdecVdis as below:

     

    Void MultiCh_deleteVdecVdis()

    {

       Bool tilerEnable;

    #if defined(TI_814X_BUILD) || defined(TI_8107_BUILD)
        tilerEnable  = FALSE;
    #else
        tilerEnable  = FALSE;
    #endif

    If this change resolve the issue  you are facing,then it is a bug that has been fixed in RDK 3.5 release
