Hello, If I erase a yaffs partition using linux 2.4.19 with yaffs1 and then put some files on it, those files don't show up when I boot into Linux 2.6.22 (using yaffs2). If I create the files under 2.6.22, they show up when I boot either Linux 2.4.19 or 2.6.22. Anyone have any ideas about this problem? Any help greatly appreciated. Rick Here are my Linux 2.6.22 specifics: yaffs2 version: yaffs2-ian-20070523.tgz NAND chip (512/16): Flash chip found: Manufacturer ID: 0x98, Chip ID: 0x75 (Toshiba TC58256FT/DC) 1 flash chips found.
