Intel Strataflash

[Stephane List <stephane.list@lilotux.net>]

Hi,

I'm using a 2.4.17 linux kernel for an embedded product.
On my card I've got 4 Intel Strataflash 16 bits / 16 Mbytes.

Flash 1 : 
-Chip Select : 0
-Data Bus connected on D0-D15 of my CPU

Flash 2 :
-Chip Select : 0
-Data Bus connected on D16-D31 of my CPU

Flash 3 and 4, same thing with Chip Select 1.


When I load the module I've got the following message :
"genprobe_new_chip called with unsupported buswidth 2"

Could you tell me if my .config is OK ?
Thanks

PS : I couldn't compile my kernel with the CVS code...

My .config has the following options :
#
# RAM/ROM/Flash chip drivers
#
CONFIG_MTD_CFI=m
# CONFIG_MTD_JEDECPROBE is not set
CONFIG_MTD_GEN_PROBE=m

#Because the data bus of the CPU is 4 bytes
