[U-Boot-Users] nfs root issue

[Seingier François-Xavier]

hello,

now that u-boot works perfeclty alright on my EP405 board, I am testing some Linux features and am having problem with booting with a nfs root file system. I've googled around for hours now (and read the DULG manual too ;) and although this is not u-boot related, I guess some of you embedded guys may have encountered the same problem. If I use a ramdisk, I can mount the nfs partition (with -o nolock,nfsvers=2); so I'm running out of clues for now. The bootargs variable is set to: root=/dev/nfs IP=192.168.1.15:::::255.255.255.0::eth0 nfsroot=192.168.1.10:/opt/embedded/tools/ppc_4xx,v2 rw
Any hint would be greatly appreciated. (and forgive me for sending this message on the u-boot list Wolfgang, but other mailing lists did not point me to working clues)

During the boot process, I get:

Looking up port of RPC 100003/2 on 192.168.1.10
RPC: rpc_getport_external(192.168.1.10, 100003, 2, 17)
RPC: xprt_sendmsg(0) = -101

Indeed, this _is_ off topic here.

embedded guys may have encountered the same problem. If I use a ramdisk,
I can mount the nfs partition (with -o nolock,nfsvers=2); so I'm
root=/dev/nfs IP=192.168.1.15:::::255.255.255.0::eth0
nfsroot=192.168.1.10:/opt/embedded/tools/ppc_4xx,v2 rw
Any hint would be greatly appreciated. (and forgive me for sending this

Well, I think that the DULG shows this a bit differently, doesn't it?

Why are you writing "IP=" when all available documentation has "ip=" ?
Why are there so many colons in your argument?

Documentation/nfsroot.txt says:

ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>

Will you please compare this with your string?

Read: Network is unreachable

Blame it on yourself for being unable to copy and paste from the
available documentation.
