linux
1. Install nfs server
sudo apt-get install nfs-kernel-server
2. Modify the configuration file /etc/exports
vim /etc/exports
Add in the last line
/home/stu/nfs *(rw,sync,no_root_squash,no_subtree_check)
Where /home/stu/nfs is the directory you want to mount
3. Port Mapping
sudo service rpcbind restart
4. Restart
sudo service nfs-kernel-server restart
5. Testing
showmount -e
mini2440
mount -t nfs -o nolock 192.168.0.102:/home/stu/nfs /mnt
Use this command when you want to transfer larger files
mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.0.102:/home/stu/nfs /mnt
/mnt is the directory on mini2440
192.168.0.102 is the IP address of the Linux host
Before mounting, make sure the mini2440 development board can ping the Linux host
Linux's /home/stu/nfs will be mounted on mini2440's /mnt
2440 boots through the kernel in nfs
1. Reboot to enter the u-boot interface first
2. Set ipaddr and serverip
OpenJTAG> set ipaddr 192.168.1.17
OpenJTAG> set serverip 192.168.1.103
OpenJTAG> save
3. Ping the host to see if it works
OpenJTAG> ping 192.168.1.103
ERROR: resetting DM9000 -> not responding
dm9000 i/o: 0x20000000, id: 0x90000a46
DM9000: running in 16 bit mode
MAC: 08:00:3e:26:0a:5b
could not establish link
host 192.168.1.103 is alive
See alive is available
4. Start the kernel through nfs
nfs 32000000 192.168.1.103:/home/book/nfs/uImage_4_3;bootm 32000000
