Boot with NFS on MIPS32

[mikezh]

Hi All,

I have one MIPS32 embedded system with Linux Kernel 2.6.23.17. Right
now, I have problem to boot from NFS. The NFS server works fine. I am
able to mount the directory from anther Linux work station. I attach
the .config file, there maybe some config flags I forget to open.

Thanks for your help,

Mike


Here is the kernel command line:
===========================
Kernel command line: root=/dev/nfs rw
nfsroot=47.1.1.108:/localdisk/rootfs/
ip=47.1.1.2:47.1.1.1:255.255.255.0:Min-MIPS:eth0:off

Here is the error:
===========================
TCP cubic registered
NET: Registered protocol family 1
NET: Registered protocol family 10
lo: Disabled Privacy Extensions
IPv6 over IPv4 tunneling driver
sit0: Disabled Privacy Extensions
NET: Registered protocol family 17

Please append a correct "root=" boot option; here are the available partitions:

I believe you need to enable "Kernel level autoconfiguration" which is
under Networking->Networking support->Networking options->TCP/IP
networking (IP_PNP), and then you'll have a "Root file system on NFS"
option (ROOT_NFS) available under Network File Systems.
