VFS: Unable to mount root fs via NFS, trying floppy.

VFS: Cannot open root device "nfs" or unknown-block(2,0)

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

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

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

do not forget any steps
