Host shared file system
First, the host needs to configure NFS and share the file system
Setting kernel parameters
The kernel parameters are set as follows:
console=ttySAC0 root=/dev/nfs nfsroot=172.20.11.88:/root/linux_kernel/rootfs ip=172.20.11.41:172.20.11.88:172.20.11.1:255.255.255.0:S3C2440A:eth0:off
Kernel parameter description
The meaning of its parameters are as follows:
nfsroot is the IP address of your development host.
After "ip=":
The first item (172.20.11.41) is the temporary IP of the target board (be careful not to conflict with other IPs in the LAN);
The second item (172.20.11.88) is the IP address of the development host.
The third item (172.20.11.1) is the setting of the gateway (GW) on the target board;
The fourth item (255.255.255.0) is the subnet mask;
The fifth item is the name of the development host (generally it doesn’t matter, you can fill it in casually)
eth0 is the name of the network card device.
Startup Results
You can see that the target board successfully mounts the file system from NFS.
