Does JFFS2 compress data in flash?
When I check the available space in Flash
df
Filesystem 1k-blocks Used Available Use%
Mounted on/dev/mtdblock1 32000 5772 26228
18% /
But when I erase a file that is 702k big I get:
df
Filesystem 1k-blocks Used Available Use%
Mounted on/dev/mtdblock1 32000 5648 26352
18% /
Which means that 124k have been freed.
I think there is a compression algorythm involved...?
Thanks a lot
