1.boot
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
2.init & load
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
