Hi,

I am using Linux Kernel 2.6.10 and enabled the JFFS2 file system in the ker=
nel.
Flash has a partition ( 0xA0980000 ) which will be used for JFFS2 and
it's erased.

After booting the kernel,  when i try to mount the JFFS2 partition
from flash, it works fine and it's empty.

When i try to copy any data to mounted partition then it gives following er=
ror.

***************************************************************************=

Pl. note that Same Kernel Image and ramdisk works fine with Intel W18
(28F128W18) flash but doesn't work with Intel Strata L18 (28F256L18)
flash.

Can anyone tell me what could be the issue as both the flashes are CFI
compliant ?

Thanks in advance
Niraj
