Not that I know of, but assuming you can boot that working jffs2 image 
you can ask the Linux kernel what is the erase block size.

   target$ cat /proc/mtd
   dev:    size   erasesize  name
   mtd0: 00020000 00010000 "bootloader"
   mtd1: 00020000 00010000 "params"
   mtd2: 00400000 00010000 "kernel"
   mtd3: 00bc0000 00010000 "filesystem"

Note the "erasesize" column.

Hope this helps,
Gilad
