Subject: mmap for JFFS2
Date: Mon, 30 Jul 2007 13:35:30 +0400 [thread overview]
Message-ID: <46ADB0E2.00996E.05372@e-post15> (raw)
Hi!
I use JFFS2 on NAND flash. Some apps require memory mapped file
opened with MAP_SHARED for read/write. But 'mmap' returns EINVAL,
since 'writepage'doesn't implemented for JFFS2 (even in 2.6.22 kernel).
It seems what I have to do it by myself. But I have some doubts.
Why it is not imlemented yet? What the troubles occur for JFFS2 developers?
Does anybody know some workarounds?
P.S. I can't change anything within given apps.
WBR, Alex Khristianovsky.
