  Please append a correct "root=" boot option; here are the available partitions:

 

  解决办法：

    (1) nfs服务器是否启动，mount是否正确

          /etc/init.d/nfs-kernel-server restart

          showmount -a 查看本机mount

    (2) tftp服务器是否启动

         service xinetd restart

    (3) ip设置是否正确，网线接口是否正常

        printenv && ping serverip

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

  Please ensure that SysLink's device driver module (syslink.ko) is installed   



  解决办法：

      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
