Subject: NFTL device not found (boot floppies)
Date: Thu, 21 Aug 2003 20:06:56 -0400 [thread overview]
Message-ID: <000601c36841$4d06a570$3301a8c0@SIMOTORSPORTS> (raw)
I'm building a couple boot floppies for my target system - an Elan/586
based system with a 32MB DOC 2000. I built the kernel with MTD built in
(not modules) according to the faq. On bootup I get the following:
----
NFTL driver: nftlcore.c $Revision: 1.94 $, nftlmount.c $Revision: 1.34 $
DiskOnChip 2000 found at address 0xE0000 Flash chip found: Manufacturer
ID: EC, Chip ID: 75 (Samsung: NAND 32MiB 3,3V) 1 flash chips found.
Total DiskOnChip size: 32 MiB Could not find valid boot record
NFTL: could not mount device
----
Could this be because I'm using 2-floppy boot system with the /dev fs on
the second floppy (which hasn't been inserted yet)? After I insert it
and /dev is loaded, I try to do anything with /dev/nftla I get errors. I
made /dev/nftla and /dev/nftla1 using 'mknod /dev/nftla b 90 0' and
'mknod /dev/nftla b 90 1' on the 2nd boot disk.
% fdisk /dev/nftla
Unable to open /dev/nftla
% fdisk /dev/nftla1
Unable to open /dev/nftla1
I can see the MTD via /proc:
% cat /proc/mtd
dev: size erasesize name
mtd0: 02000000 00004000 "DiskOnChip 2000"
Any ideas?
