Hello All, I downloaded the newest CVS tarball through webcvs and used it in Linux 2.6.14 on ARM 9 cpu. On the 2K page Nand flash, after mount this nand flash as a Yaffs2 file system, I can copy files to it. However, After umount and remout this nand flash, all files I copied are missing! How to narrow down this problem? Thanks! Tyler Li
