Hi,
Yeah that was the problem. So now it boots all the way. I am not sure what this Simple Ramdisk-Image is composed of as I do not get to a promt. I get nothing on the terminal.

Shamile,
Do you have the proper fs (e.g. ext2, minix, or whatever your ramdisk is) support configured in the kernel? Looks like it finds the ramdisk but can't decipher contents.
HTH, Kyle.

Hi,
I am trying to get Linux to boot with U-boot using a
flash
based initrd image. I am using a Memec Virtex II Pro
board
which has a Powerpc 405 processor embedded in an FPGA.
I
have u-boot running. My flash is 8 Megs and is
organized as
follows:
0xFE000000 - U-boot 0xFE100000 - Linux u-boot kernel (vmlinux.PPCBoot)
created
using latest sources from ppckernel.org 0xFE200000 - Simple Ramdisk-Image
(simple-ramdisk.PPCBoot )
from DENX.de
The boot arguments I pass using u-boot are bootargs=console=ttyS0,115200 mem=32M root=/dev/ram rw
Some relevant kernel configuration parameters are
(using
xilinx_ml300 as base)
# Block devices CONFIG_BLK_DEV_RAM=y CONFIG_BLK_DEV_RAM_SIZE=4096 CONFIG_BLK_DEV_INITRD=y
# File systems CONFIG_TMPFS=y CONFIG_RAMFS=y
However when I use "bootm fe100000 fe200000" to boot
linux,
I get all the way to the end of the boot process at
which
point I get this message:
RAMDISK: Compressed image found at block 0 Freeing initrd memory: 554k freed Kernel panic: VFS: Unable to mount root fs on 01:00
Seems like it located the RAMDISK image but is not able
to
mount it. Any ideas on what is causing this to occur.
I did a backtrace using gdb over abatron and heres
what I
get (breakpoints don't seem to work for me though
although
I can get a stach trace) #0 0xc000678c in __delay () #1 0xc0014734 in panic (fmt=0x1cfde0 <Address 0x1cfde0
