[Yaffs] yaffs seems do not work correctly

    Hello ,

    I am using an ARM machine with 2.4.18 kernel with a NAND 

    flash Samsung K9D1208V0M

    I configured the kernel for yaffs 

    I mounted this file system

    but if I create a file [ editing it by VI ] , the ls command don't
list it

    if I do a cat , the file is printed correctly

    At the next boot the file disappear

    Any help will appreciated
