JFFS2 compresses the data. I get about 2:1 comression with ARM executable
cdde; it looks like you got a little more, maybe because the content is
more predictable, e.g. contains some text. Don't expect it to be effective
on already compressed files, e.g. MP3, JPEG, AVI.
Now if I could only put JFFS3 on a 1 GB removeable MMC card, bypassing the
(on-chip?) disc emulation layer... Sigh. This is on a Nokia 770.
