[Yaffs] Về: A Three YEARs Problem!!!-----Can not see file a…

Hi,
You should look into the kernel source code to find the solution. For example, I am using linux kernel 2.6.29.3. Come to driver/mtd/nand/,
and read into nand_base.c. You see that:

static struct nand_ecclayout nand_oob_64 = {
     .eccbytes = 24,
     .eccpos = {
            40, 41, 42, 43, 44, 45, 46, 47,
            48, 49, 50, 51, 52, 53, 54, 55,
            56, 57, 58, 59, 60, 61, 62, 63},
     .oobfree = {
         {.offset = 2,
          .length = 38}}
};

Is that your NAND which has 64 bytes in OOB ? And you are using this definition for your NAND ?
If the offset = 2 then you can be use command "mkyaffs2image /tmp/test/ /tmp/yaffs2.img 2".
So offset = x, using:
mkyaffs2image /tmp/test/ /tmp/yaffs2.img x

Make clearly what is your definition of your NAND 's OBB.
Best, regard

>>Hi

>>Thank you for your reply.

>>I can new files and new folders in /mnt/nandyaffs2 after mount the nand.
>>But I can not nandwrite a yaffs2 imge into NAND and get only lost+found.
>>Why?
>>Confused!!!!!

>>My English is not good either, and thank you for your patience.
