unable to get NAND oobinfo

["Rudi Engelbertink" <rudi@unsec.nl>]

Hi,

trying to get my nand driver (for compulab 586core board) on kernel 2.4.27
working, i ran into the following problem:
The driver is recognised and appears to work. That means I can read the mtdchar
device but whin I'm trying to format the device, I recieve the message
'flash_eraseall: /dev/mtd3: unable to get NAND oobinfo'
An strace replies with:
open("/dev/mtd3", O_RDWR)               = 3
ioctl(3, 0x80204d01, 0xbffffdf0)        = 0
ioctl(3, 0x80c84d0a, 0xbffffd20)        = -1 ENOTTY (Inappropriate ioctl for
device)
At that moment it does an ioctl(fd, MEMGETOOBSEL, &oobinfo) but it looks
like the device is not registered properly.

NAND device: Manufacture ID: 0xec, Chip ID: 0x76 (Samsung NAND 64MB 3,3V)

On the mailing list I found an email with the same question about this but no
answer.
Could you give me a hint about what is going wrong or a posible solution.

RGDS Rudi.
