OK6410 starts automatically mounting the nfs file system

①Start and stop the nfs service of the ubuntu server through commands:

Run from the command line:

      /etc/init.d/nfs restart

Use this command to stop the nfs service:

      /etc/init.d/nfs stop

Check whether the nfs server is enabled:  

      service nfs status

Restart the corresponding 2 services:      

      service portmap restart 

      service nfs restart

Check the firewall to see if the nfs port is blocked

      service iptables stop

      service iptables status

②Set permissions for the Ubuntu directory to be mounted:

sudo vi /etc/exports

Add to:

/home/book/workspace/ok6410_project/fs_ok6410_yaffs2 *(insecure,rw,async,no_root_squash)

sudo chown book:book fs_ok6410_yaffs2/ -R

chmod 755 /home/book/workspace/ok6410_project/fs_ok6410_yaffs2

Try mounting yourself:

mount -t nfs -o nolock,vers=2 192.168.48.104:/home/book/workspace/ok6410_project/fs_ok6410_yaffs2 /mnt

mount -t nfs -o nolock 192.168.48.104:/home/book/workspace/ok6410_project/fs_ok6410_yaffs2 /mnt

③Set the development board IP parameters:

  vi /etc/init.d/rcS Make the following changes at the end of the file to allow the kernel to automatically configure network parameters and open the network card connection after startup:

  ifconfig eth0 192.168.16.16

  ifconfig eth0 up

④Modify u-boot startup parameters:

default value:

bootargs=root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc console=ttySAC0,115200

set bootargs root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc console=ttySAC0,115200

After changing to NFS startup:

seten bootargs noinitrd root=/dev/nfs nfsroot=192.168.48.104:/home/book/workspace/ok6410_project/fs_ok6410_yaffs2 ip=192.168.48.100:192.168.48.104:192.168.48.255:255.255.255.0::eth0:off init=/linuxrc console=ttySAC0,115200

save

⑤Restart the development board:

reset

reboot
