Subject: JFFS2 needs approx 72B of RAM per file
Date: Tue, 08 Apr 2008 01:14:19 +0200	[thread overview]
Message-ID: <47FAAACB.2060800@telenet.be> (raw)

Hello to ecos-discuss and especially linux-mtd,

Tests have revealed to me that jffs2 does not only need raw nodes in RAM 
(I use CYGNUM_FS_JFFS2_RAW_NODE_REF_CACHE_POOL_SIZE to have this 
statically), but also "eats RAM" per file in flash.
I want to remove this allocation, but I don't know if this is possible, 
what are the disadvantages....?
(my basic problem is that I have not enough RAM on my board, but it is 
too late to change HW for the running projects)

After reading some jffs2 documentation, I think that my problem is the 
inode cache?


Kind regards,
Juergen Lambrecht
