[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: sendmsg returned error 101

Here are some information about the host:
