persistence of files using jffs

When umount and then remount, any new files I copied are
not there.
Our system has 4 Intel Strataflash chips that are coupled pairs
to give us 32MB at 32bits data width. In the structure 'map_info',
I set the 'buswidth' field to 4.
The startup code uses the write32 functions, but when I mount
I noticed that write16 functions are being used. As well, in
the file cfi_cmdset_0001.c, only write16 functions are called.
Is this causing a problem for our system?
Thanks,
