Hi, sorry if it is double posted, but I don't see my original post sent through gmane. ------------------------------------- SW: YAFFS2 built into linux 2.6.10 with recent mtd snapshot HW: at91rm9200 with 256 MB Samsung NAND hardware/linux/mtd are likely ok since I can run with jffs2 for weeks. Flash was erased before mounting yaffs2. Problems: 1. umount fails with message: VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day... 2. some files disappear after re-mounting 3. (a lot of) segmentation faults 4. df shows garbage People, has anybody managed to run yaffs2 under linux 2.6.x? Are there any patches required against tarball from: http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/cvs_root.tar.gz?tarball=1 Sergei Sharonov ------------------------------------- # mount /mnt/flash/ yaffs: dev is 32505859 name is "(unavailable)" yaffs: Attempting MTD mount on 31.3, "(unavailable)" yaffs: yaffs_GutsInitialise() yaffs: yaffs_GutsInitialise() done. #
