I am using the kernel of dvesdk package, and have files under fs/yaffs2/ directory
and my .config file as bellow: CONFIG_YAFFS_FS=y CONFIG_YAFFS_YAFFS1=y #CONFIG_YAFFS_DOES_ECC is not set CONFIG_YAFFS_YAFFS2=y CONFIG_YAFFS_DISABLE_CHUNK_ERASED_CHECK=y CONFIG_YAFFS_SHORT_NAMES_IN_RAM=y is it not be build into the kernel?

Unmount the filesystem and do flash_eraseall /dev/mtd5 mount -t yaffs2 /dev/mtdblock5 /mnt/fonts I do not believe yaffs2 support is in any kernels yet, so you need to patch your kernel, or build the module out-of-tree. > 2009-11-02 > ------------------------------------------------------------------------ > e-eo > ------------------------------------------------------------------------ > *发件人：* Brian G Rhodes > *发送时间：* 2009-11-01 17:40:07 > *收件人：* e-eo > *抄送：* davinci-linux-open-source > *主题：* Re: About big file on jffs2 filesystem > e-eo wrote: > > hi, all, > > Reboot the system when operating the big file on jffs2 filesystem > > based nandflash. this operation allways lead the file system CRC wrong > > when mounting.
