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

Hi

I am installing the linux kernel 2.4.26 in the FPGA = Virtex II Pro following the instruction of

 

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 operati=F3n 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 =3D 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=3D" 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=3Dremount-ro 0 0 =
