dvr rdk v03.50.00.06 with 2GB DDR configuration

Can you disable call to System_disableTilerAllocator from the usecase file multich_vdec_vdis.c and check if you still see the crash.

When System_disableTilerAllocator is called, it creates a normal frame buffer heap over the tiler physical memory .This is because usecase doesn't use tiled memory so the memory allocated to tiled memory is reused for frame buffers. This requires the tiler physical memory to be mapped on VPSS M3 . In 2G build there are not enough pages  to map the tiler physical memory to VPSS M3 so it is incorrect to dsableTilerAllocator. The correct fix for this is:

/dvr_rdk/mcfw/src_bios6/links_m3vpss/system/systemLink_tsk_m3vpss.c

Int32 SystemLink_cmdHandler(SystemLink_Obj * pObj, UInt32 cmd, Void * pPrm)

         case SYSTEM_COMMON_CMD_TILER_DISABLE_ALLOCATOR:
        {
            #ifdef TI816X_2G_DDR
            Vps_printf("WARNING!!.Tiler Memory cannot be accessed by M3 in 2G build.Will not disable");
            #else
            status = Utils_tilerAllocatorDisable();
            #endif
            break;
        }
        case SYSTEM_COMMON_CMD_TILER_ENABLE_ALLOCATOR:
        {
            #ifdef TI816X_2G_DDR
            Vps_printf("WARNING!!.Tiler Memory cannot be accessed by M3 in 2G build.Will not enable");
            #else
            status = Utils_tilerAllocatorEnable();
            #endif
            break;
        }
