Question Filesystem supported but MTD not mounted


Hello

I'm having the following issue on an appliance using uClinux and MTD to access a NAND flash memory: Although the kernel has Yaffs compiled and it seems able to access the NAND, it doesn't create devices (/dev/mtdblock? and /dev/mtd?):

Code:
root:~> dmesg
Linux version 2.6.19.3-ADI-2007R1.1-svn (root@ubuntu) (gcc version 4.1.1 (ADI 07R1)) #1 Thu Feb 10 15:37:08 CET 2011
Blackfin support (C) 2004-2007 Analog Devices, Inc.
Compiled for ADSP-BF532 Rev 0.5
...
yaffs Feb 10 2011 15:35:53 Installing.
...
uclinux[mtd]: RAM probe address=0x3b00000 size=0x400000
Creating 1 MTD partitions on "RAM":
0x00000000-0x00400000 : "ROMfs"
uclinux[mtd]: set ROMfs:EXT2  to be root filesystem
Generic platform RAM MTD, (c) 2004 Simtec Electronics
NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB 3,3V 8-bit)
Scanning device for bad blocks
Creating 2 MTD partitions on "NAND 256MiB 3,3V 8-bit":
0x00000000-0x00800000 : "linux kernel"
0x00800000-0x10000000 : "file system"
...
VFS: Mounted root (ext2 filesystem).
Does someone know what can prevent Linux from creating devices?

Thank you.

Question

Dont know if this will help, but...

Im working with a Debian version for a 'netbook' and, when I have it set up to use the USB-based flash RAM (which would normally show up as /dev/sda) as the filesystem, it will NOT show up mounted as mnt/sda. I CAN mount it to /mnt/sda1 if I choose, but then I have duplicate access to the / filesystem.

Perhaps the same situation is happening with yours?

Thanks for the tip. I ended up using a new, different Linux image that erased the NAND and the problem went away.
