JFFS2 needs approx 72B of RAM per file


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
