Re: [Ltib] RE: Linux 2.6.34 for FDI board and NFS issue

[Jorge A. Castro]

Hi to all,

Kevin: I create the device in the root fs. I added a line in the device_table.txt file, which is in the ./ltib/bin . Even though, I still get the message "Warning: unable to open an initial console." (I verified that the dev node was create in ./ltib/rootfs/dev)

Mike and Daniel: You were right! The ethaddr is needed in the u-boot bootargs configuration. I confirm that looking more in the mailing list archives

I'm going to explain, more or less, the steps I did in order to have linux 2.6.34 running on my FDI3250 board with NFS root fs.

1. Set the u-boot parameters, like:
    baudrate=115200
    ethaddr=00:1a:f1:00:00:00
    bootcmd=tftpboot; bootm
    bootfile=uImage
    loadaddr=0x80100000
    bootdelay=2
    serverip=192.168.100.84
    ipaddr=192.168.100.85
    gatewayip=192.168.100.50
    netmask=255.255.255.0
    root=/dev/nfs

    To set the bootargs, I did it following some explained by Henry in http://lists.gnu.org/archive/html/ltib/2010-07/msg00035.html. So I did

    setenv build_param 'setenv bootargs console=ttyTX0,115200n81 root=/dev/nfs rw nfsroot=192.168.100.84:/home/jcastro                    
    /ltib/rootfs,wsize=1500,rsize=1500 ip=192.168.100.85 ethaddr=${ethaddr} init=/sbin/init'

    and then
   
    run build_param
    saveenv

2. The NFS server in the host machine is set in the /etc/exports like

    /home/jcastro/ltib/rootfs 192.168.100.*(rw,no_root_squash,no_subtree_check,async)

3. And of course, set all needed in the LTIB configuration to have the root filesystem in NFS

All set as above is what allow me have the board running the 2.6.34.

Thanks to all for their answers, I hope this will help those who will implement this distribution in their FDI3250 boards. I paste here my boot output.

Hi Jorge,

Mike's suggestion is correct. The LPC32xx ethernet driver needs ethaddr from the bootargs. For Linux-2.6.27.8, the 'ethaddr' is stored in SPI EEPROM. For Linux-2.6.34, the 'ethaddr' is stored in u-boot environment.

>From your boot log, it seems like the 'ethaddr' is not set properly:
---------------------------------------------------
Kernel command line: console=ttyTX0,115200n8 root=/dev/nfs rw 
nfsroot=192.168.100.84:/tftpboot/rootfs,wsize=1500,rsize=1500 ethadd
r=${ethaddr} ip=dhcp init=/sbin/init

Kevin:

I have been told by others on this list that for 2.6.34 the bootargs
need an additional argument, ethaddr.  For example:

bootargs=console=ttyS0,115200n81 root=/dev/mtdblock4 rw
rootfstype=jffs2 ip=dhcp init=/sbin/init ethaddr="xx:xx:xx:xx:xx:xx"

Where xx:xx:xx:xx:xx:xx in the Ethernet MAC or hardware address, not
the IP address.
