I am using eCos (http://sources.redhat.com/ecos) on a ARM7 
microcontroller. Now I would like to add YAFFS support (direct 
access-mode) to eCos for using a filesystem on a 64MB NAND-flash (the 
JFFS2 is still not working correct with NAND-flashs under eCos).

Has someone any experience concerning this topic or something similar - 
or exist some more implementation instructions for YAFFS?
