Hi all,
I have problems in generating a bootable device (CF)
During the setup the CF is connected to the host via an USB adapter.
These are the steps I do:
# fdisk /dev/sdb
create a linux partition /dev/sdb1 and activate it
# mkfs.ext3 /dev/sdb1
# mount -t ext3 /dev/sdb1 /media/disk
# cd /media/disk
# tar
-xvf /home/paolo/oe/stuff/build/gpe-image/deploy/glibc/images/i586-generic/gpe-image-i586-generic.tar
and the filesystem is correctly on the CF
# cd boot
# mkdir grub
# cd grub
# < copy of grub files>
# grub ...
the menu.lst contains
title OpenEmbedded Linux (hda1)
root (hd0,0)
kernel /boot/bzImage-2.6.21 root=/dev/hda1 ro
quiet
The system boots, but when the filesystem is created, the kernel crashes
with the message:
VFS: Cannot open root device "(hd0,0)" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs or
unknown-block(0,0)
but I don't understand what I have to do...
Thanks in advance
Paolo
