             make sure:    ifeq ($(DVR_RDK_BOARD_TYPE ), )
                               DVR_RDK_BOARD_TYPE := DM816X_TI_EVM
                            endif

            DM816X_TI_EXM   is  my board_type

        and reset  dvr_rdk_BASE :  
             ifeq ($(OS),Linux)
                        dvr_rdk_BASE     := /home/erik/dvrrdk/DVRRDK_04.01.00.02
                        TI_SW_ROOT       := $(dvr_rdk_BASE)/ti_tools
                     endif

            dvr_rdk_BASE  is the  file path
