Xilinx BSP for linux 2.6

[Ming Liu]

Dear Ameet,
It Works now! By creating these character and block devices in /dev, the 
system go further now. But another problem appears. That is, there is no 
login prompt shown in hyper terminal. The information is listed as:

[    1.745076] loop: loaded (max 8 devices)
[    1.793385]  xsa: xsa1 xsa2 xsa3
[    1.839258] mice: PS/2 mouse device common for all mice
[    1.925011] VFS: Mounted root (ext2 filesystem) readonly.
[    1.990035] Freeing unused kernel memory: 76k init

Welcome to ML403 powerpc linux 2.6.16-rc5, E.I.S. edition

Starting system...
mounting /proc: done.
Mounting '/' read-write: mount: Cannot read /etc/mtab: No such file or 
directory

done.
brining up loopback interface: ifconfig: socket: Function not implemented
done.
Mounting /tmp: done.
Starting syslogd: done.
Starting klogd: syslogd: Couldn't get file descriptor for socket /dev/log: 
Funct
ion not implemented
done.
Starting inetd: done.
System started.

My inittab files looks like:
::sysinit:/etc/init.d/rcS
#::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/sbin/getty 9600 tts/0

Any suggestion about this problem? Thanks in advance.

Regards
Ming
