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

Maybe just a typo? I think it should be 'disc0' not 'disco0'

Hi Jose,
I didn't see that you configured the kernel to put the Xilinx system ace driver in?
It's under device drivers, block devices.
Thanks,
John
