with this tree and the brian branch I get:

root at armv5te:/home/hs/bmk/mtd-utils# ./flash_erase -j /dev/mtd7 0 0
flash_erase: error!: /dev/mtd7: unable to get NAND oobinfo
             error 22 (Invalid argument)
root at armv5te:/home/hs/bmk/mtd-utils#

:-(

As I see in mtd-util:flash_erase.c line 197:

if (ioctl(fd, MEMGETOOBSEL, &oobinfo) != 0)
              ^^^^^^^^^^^^
              this is the "old" style ... which fails ...

bye,
Heiko
