ML403 2.6 kernel, root file system on NFS, stops after freeing unused kernel memory

[Mohammad Sadegh Sadri]

dear grant

As i said i'm using ELDK 4.0 root file system via NFS

ML403 gets IP address from DHCP , mounts the root file system via NFS and then simply stops printing messages on the screen. The board is alive because it answers ping requests.

-- VFS: Mounted root file system (nfs filesystem)
-- Freeing unused kernel memory :108k init
( No more messages after here , hyperterminal does not show anything more )

I have chosen my root file system to be /home/sadri/hld/eldk/ppc_4xx 
(/home/sadri/hdl/eldk is eldk installation folder )

/eldk/ppc_4xx/dev contains the following node:

crw-rw-rw- 1 root root 5, 1 May 16 09:08 console

and the last line for /etc/inittab is :

# Run gettys in standard runlevels
3:2345:respawn:/sbin/mingetty --noclear console

in addition I passed the init=/bin/sh parameter to the kernel with no success. 

the link is auto negotiated at 100MBPS

I'm using OPB UART 16550. 

I studied the ports by Mirek23 carefully and I know that his problem has been the definition of SDRAM size in xparameters.h , but this is not my problem. I checked that for EDK 9 it is correct.

what is your idea?

thanks
mohammad sadegh.
