Hi,

I need some help about JFFS2 and MMU.

I have a writtable JFFS2 partition on a NAND flash. I find that mounting the
JFFS2 partition is very slow (about 5 minutes for a partition of 8MB having 133
files) compare with running under Linux.
The MMU is not enabled, neither the DCache.

Should I enable MMU and DCache ? How can I do that ? I've checked the source
code on Linux, and it seems very complex.

I'm working on a ARM 926 ejs core and I'm using UBoot V1.1.6.

Thanks for your help,

Yves
