I am installing the linux kernel 2.4.26 = in the FPGA=20 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=20 that I build the root file system using the BusyBox 1.1.0 = infrastructure. I=20 configured the busybox and the kernel with the cross compiler, = finally I=20 execute the mkrootfs.sh script and obtain the all files of=20 fyle system, these files I copied to ext3 partition of CompacFlash = when I=20 probe operati=F3n by the hyperTerminal (38400 bps) appears a = error that=20 say:

Serial driver version 5.05c = (2001-07-08) with no=20 serial options enabled
ttyS00 at 0xfdfff003 (irq =3D 30) is a = 16550A
RAMDISK=20 driver initialized: 16 RAM disks of 4096K size 1024 blocksize
VFS: = Cannot=20 open root device "xsysace/disco0/part3" or 00:00
Please append a = correct=20 "root=3D" boot option
Kernel panic: VFS: Unable to mount root fs on=20 00:00
<0>Rebooting in 180 seconds.

I configured the linux kernel = with:

Code maturity level options --->

= [*]=20 Prompt for development and/or incomplete code/drivers

File systems --->

[*] /dev file system support = (EXPERIMENTAL)=20

[*] Automatically mount at = boot=20

[*] Virtual memory file system = support (former=20 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=3Dremount-ro 0 0=20
