Hi Fabio,
assuming you have a linux-based computer you may set up nfs by performing the
following steps:
- On your Host
1. Install the nfs-(kernel)-server package of your Distribution.
2. Make sure nfsd and portmap are started, if necessary please start portmap
first
3. Create the directory /nfsroot
4. Edit /etc/exports:
/nfsroot *(no_root_squash,rw)
5. Restart nfs-server
6. Copy the files from the romfs/ directory of uClinux /nfsroot
7. Create the device-Inodes in /nfsroot/dev by
7. (a) copying all of your hosts' /dev into /nfsroot/dev .
7. (b) create all devices "in-place" by using the following command directly
within /nfsroot/dev
ls -1 @* | awk -F'[@,]' '{print "mknod " $2,$3,$4,$5}' | sh
- On your target
1. Enable IP-Autoconfiguration and NFS-Root in the Kernel-Options
2. Append to the kernel-commandline, subsituting $server_ip by your hosts
IP-Address and $client_ip by your Boards IP-Address:
rootfstype=nfs root=/dev/nfs nfsroot=$server_ip:/nfsroot
ip=$client_ip:$server_ip:$server_ip:$netmask:uclinux:eth0:dhcp
3. Boot your target: Hope you're done!
Hope this helped.
Best Regards,
Peter
