Hi, I'm trying to compile the yaffs2 cvs tree for a linux 2.6.9 kernel on an arm xscale proc. I'm working with a big samsunng nand flash (256 MB, 2K page size). Up to now I can compile the obj file yaffs.o using the Makefile that comes from the cvs but when I try to compile the kernel module (yaffs.ko) within the kernel source tree (make modules) I get an unresolved symbol: *** Warning: "yaffs_InitialiseTags" [fs/yaffs2/yaffs.ko] undefined! I tryed to grep the function in the yaffs2 dir. but I've only found a dectaration in yaffs_guts.h but no definition. Am I doing something wrong? thanks. Giorgio, iw3gtf@arcor.de
