Hi:

We're trying to substitute a Numonyx Axcell M29EW (32M) Flash flash part for a Spansion S29GL chip. We seem to be having
 some difficulty trying to partition the new flash using the flashctl utility. Here is the commands (and corresponding 
output) we execute:

# devf-generic -i0 -s 0xFC000000,32M -r -u2 -b5 -L5 -t1 -v&
[1] 135179
Released Flash Library - BX630_193_release
Build: Jul  5 2005 17:06:35
devf: fs0 socket generic
devf: chip total      = 1
# devf: bus width       = 2
devf: chip interleave = 1
devf: fs0 array CFI U: 100 S: 020000
devf: fs0p0 raw U: 100

#
# flashctl -p /dev/fs0 -o 10M -l 21M -e -vvvvvv
Erasing device /dev/fs0
offset = a00000,limit = 1f00000
intel_read_status: 25 program vpp error
intel_read_status: 25 program vpp error
intel_read_status: 25 program vpp error

intel_read_status: 25 program vpp error
DCMD_F3S_ERASE failed (errno 5)
flashctl: erase failed
devf: fs0p0 raw U: 100

Anyone have any idea what might be the cause of the failure? 
The above commands do work with the Spansion part. There is a migration guide for this swap and they do mention some 
differences in the Autoselect information that has to be accounted for in software. It's not clear to me how to get this
 information to the driver though. Or maybe we need a new driver?

thanks
