Hi
I have made an bootable USB via dd command from hd.img image for a 386
architecture.
The grub run, the kernel start to boot but when root file system has to be
mount on root I see a kernel panic.
I have put the right file system in the kernel (not module).
The last part of console output is :
sdb: sdb1
[ 3.016140] sd 33:0:0:0: [sdb] Attached SCSI removable disk
[ 11.119960] VFS: Cannot open root device "sdb1" or unknown-block(8,17):
error -2
[ 11.121978] Please append a correct "root=" boot option; here are the
available partitions:
[ 11.124194] 0800 524288 sda driver: sd
[ 11.125492] 0810 3910180 sdb driver: sd
[ 11.126782] 0811 298976 sdb1
00000000-0000-0000-0000-000000000000
[ 11.128686] Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(8,17)
[ 11.130895] Pid: 1, comm: swapper/0 Not tainted 3.5.7-Anto-Embedded #12
My impression is : kernel see the partition but can't read it.
The other strange thing is UUID number 00000000-0000-0000-0000-000000000000
but if I mount the usb key in a linux machine the number is right and not 0
The kernel command line is :
root=/dev/sdb1 console=ttyS1,115200 rootdelay=10
do you have same ideas
regards, Antonio Righettini
