Flash partitions

[Ludvik Kumin]

Hi!

I am  trying to get the mtd working on the custom-made board based 
on the SA1110. It contains two Intel StrataFlash chips 28F640J3A 
(8 MB each; the first is connected to the data lines D0 - D15, the second
to D16 - D31). I manage to read/ write the flash using "dd" 
(through the device file /dev/mtd5) and also to mount the
/dev/mtdblock5 (-t jffs) device and read/write to it. 

However, while booting the kernel (2.4.16) I get the message:

>---------------------------------------------------------------------------
----------------
physmap flash device: 1000000 at 0
Using buffer write method
mtd: Giving out device 0 to Physically mapped flash
SA1100 flash: probing 32-bit flash bus
Using buffer write method
No RedBoot partition table detected in SA1100 flash   <--------- !!!
Using static partition definition
Creating 5 MTD partitions on "SA1100 flash":
0x00000000-0x00040000 : "bootloader"
mtd: Giving out device 1 to bootloader
0x00040000-0x00080000 : "bootloader params"
mtd: Giving out device 2 to bootloader params
0x00080000-0x00180000 : "kernel"
mtd: Giving out device 3 to kernel
0x00180000-0x00800000 : "RAM disk"
mtd: Giving out device 4 to RAM disk
0x00800000-0x01000000 : "jffs"
mtd: Giving out device 5 to jffs

The partition table is not detected! The part of the ".config" file
related to "mtd" is:

Q:
Has anyone experienced the same problem? 
What could be the reason the partition table is not found?
Any help would be appreciated.
