Subject: Moving from 2.2.18 + M-system proprietray code to 2.4.6 => does not work
Date: Thu, 12 Jul 2001 11:18:06 +0200 [thread overview]
Message-ID: <3B4D6B4E.2040303@crf.canon.fr> (raw)
I have been using a motherboard with a DOC 2000. I can boot from the
diskOnChip and see it as a disk device with a ext2 filesystem using
2.2.18 + Msystem patch + own cooked lilo patch...
Now I upgraded the system to a stock 2.4.6 kernel *with devfs enabled*
When I boot, I see the follwing message :
M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings, Inc.
DiskOnChip 2000 found at address 0xD8000
Flash chip found: Manufacturer ID: 98, Chip ID: 73 (Toshiba TH58V128DC)
2 flash chips found. Total DiskOnChip size: 32 MiB

nftla: p1
devfs: devfs_register(disc): NULL ops, got c02d8850 from major table
devfs: devfs_register(part1): NULL ops, got c02d8850 from major tableL
In /dev/nflt/disc0 I have two devices
/dev/nftl# ls
disc0
albator:/dev/nftl# cd disc0
albator:/dev/nftl/disc0# ls -l
total 0
brw------- 1 root root 93, 0 Jan 1 1970 disc
brw------- 1 root root 93, 1 Jan 1 1970 part1
No other things.
NB : /dev/discs/disc1# ls -l
total 0
brw------- 1 root root 93, 0 Jan 1 1970 disc
brw------- 1 root root 93, 1 Jan 1 1970 part1
But I can not mount the filesystem. The filesystem is valid as it works
with the 2.2.18 kernel...
Any idea?
