  解決辦法：
    (1) nfs服務器是否啓動，mount是否正確
          /etc/init.d/nfs-kernel-server restart
          showmount -a 查看本機mount
    (2) tftp服務器是否啓動
         service xinetd restart
    (3) ip設置是否正確，網線接口是否正常
        printenv && ping serverip

  syslink: disagrees about version of symbol module_layout                        
  insmod: error inserting './kermod/syslink.ko': -1 Invalid module format

  Dev_pollOpen: Couldn't open /dev/syslinkipc_Osal: No such file or directory

  解決辦法：
      1 . check the Rules.make<../dvrrdk/DVRRDK_04.01.00.02/dvr_rdk/Rules.make>,

         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

       2.  make and install the  rdk
      do as DM81xx_DVR_RDK_Install_Guide.pdf
             do not forget any steps
