Hi,
  The mkfs.jffs2 has some options,  in which  -e option specifies the
erase block size, which  by default is 64KiB.
While making a jffs2 image of a directory (which has some files) of size
3848192 Bytes.

 ./mkfs.jffs2   -d directory   -o jffs2_img  -e  128KiB

With default option for erase block size ( 64KiB), the jffs2 image size
was :   1983612 Bytes. ( 1.89 MB)
 With   -e 128KiB
, the jffs2 image size was :    7687900 Bytes  (7.33 MB)
  With   -e  256KiB
, the jffs2 image size was :    4289164 Bytes   (4.09 MB)

Why is that the jffs2 image size is varying with the erase block size.?
 If i have an erase size of 256KiB(on flash), is it necessary that i
should build a jffs2 image with the -e 256KiB option.


regards
ashok
