Hi
I am installing the linux kernel 2.4.26 in the FPGA Virtex II Pro following the 
instruction of 
http://www.cs.washington.edu/research/lis/empart/xup_ppc_linux.shtml

I compiled the linux kernel successfully, after that I build the root file 
system using the BusyBox 1.1.0 infrastructure. I configured the busybox and the 
kernel with the cross compiler, finally I execute the mkrootfs.sh script and 
obtain the all files of fyle system, these files I copied to ext3 partition of 
CompacFlash when I probe operatión by the hyperTerminal (38400 bps) appears a 
error that say:

Serial driver version 5.05c (2001-07-08) with no serial options enabled
ttyS00 at 0xfdfff003 (irq = 30) is a 16550A
RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize
VFS: Cannot open root device "xsysace/disco0/part3" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00
 <0>Rebooting in 180 seconds.


I configured the linux kernel with:

Code maturity level options ---> 

            [*] Prompt for development and/or incomplete code/drivers 

File systems ---> 

    [*] /dev file system support (EXPERIMENTAL) 

     [*] Automatically mount at boot 

    [*] Virtual memory file system support (former shm fs) 

    [*] /proc file system support 

General Setup ---> 

    [*] Networking support 

    [*] Sysctl support 

    [*] System V IPC 



and edit the /etc/fstab 

tmpfs /dev/shm tmpfs nodev,nosuid,noexec 0 0 

proc /proc proc defaults 0 0

/dev/root / auto defaults,errors=remount-ro 0 0
