[Ltib] Linux 2.6.34 for FDI board and NFS issue

[Jorge A. Castro]

Greetings to all in LTIB mailing list!

For those who don't know, Linux 2.6.34 for the Future Design Inc board 
(or FDI board) with LPC3250 is available and also some upgrades to the 
2.6.27.8 according to http://www.lpclinux.com/Main/WebHome. Thanks to 
Kevin Well and the guys of LPCLinux.

Now I'm trying to implement the 2.6.34 version on my FDI3250. I 
configured it similar than the 2.6.27.8 version. It compiled ok, but I 
have problems when mounting the roofs by nfs. Seems that is mounted but 
I got something like:

rtc-lpc32xx rtc-lpc32xx: setting system clock to 1970-01-01 00:34:55 UTC 
(2095)
Sending DHCP requests .., OK
IP-Config: Got DHCP answer from 0.0.0.0, my address is 192.168.100.115
IP-Config: Complete:

host=192.168.100.115, domain=, nis-domain=(none),
bootserver=0.0.0.0, rootserver=192.168.100.84, rootpath=
Warning: unable to open an initial console.

nfs: server 192.168.100.84 OK
nfs: server 192.168.100.84 OK

And I never got access to the system. I expirience something like this 
in the past and I fixed with the configuration of bootargs in the u-boot 
with wsize=1500,rsize=1500 parameters to the nfs root, like:

bootargs=console=ttyTX0,115200n81 root=/dev/nfs 
nfsroot=192.168.100.84:/tftpboot/rootfs,wsize=1500,rsize=1500 rw noinitrd ip


Nevertheless, this is not working now. Kevin, or any one else, have any 
idea what can I be missing? I don't know if a need some especial 
configuration in the u-boot or in the LTIB. Any idea will be welcome, 
because I have spend a lot of time without success.

Thanks and best regards.


P.S.: Here I put the entire boot output and the u-boot parameters that I 
have set.
