Hi All

this File system.

<*> CFI Flash device in physical memory map
â â

Earlier,i was facing same problem while mounting any MTD block then i
used the physical mapped flash map instead of the ixp_4xx map .
Now,I only able to mount but failed to unmount MTD device :P
Please help me out !
This is purely a JFFS2 problem and has nothing to do with RedBoot/eCos
- take it up with the folks that support JFFS2.
