不对,我检查过了,这个是我误笔.实际我写对了，但是加载后还是提示

今天再重新十多次，
发现在压缩编译内核时提示下面错误，我已经下载了最新的yaffs2补丁，
但是依然如此：
-------------------------------------------------------------------------------------------------
fs/yaffs2/yaffs_guts.c:1577: warning: 'yaffs_DeleteWorker' defined but not used
fs/yaffs2/yaffs_guts.c:602: warning: 'yaffs_VerifyTnodeWorker' defined but not used
--------------------------------------------------------------------------------------------------------


我的内核boot是这样写的
noinitrd root=/dev/mtdblock3 init=/dev/linuxrc console=ttySAC0,115200

你不对的地方多了：
1. 内核实际用的是设备(31, 2)，也就是mtdblock2, 挂载rootfs, 这显然和你想要的mtdblock3不一样；
2. 内核没有尝试用yaffs2来挂载rootfs, 最有可能的错误是yaffs2没有被编译进你所用的内核镜像。

哦...我昨天一直以为root值应该文件系统..原来是内核..谢谢帮主带领出误区.
yaffs2我已经选上了.但是还是会提示错误.

版主...经过一段时间的研究...翻基础看..有点明白了.也成功了..

vivi            :             0x00000000      0x00040000      0

---------------------------------------------------------------------------------------
vivi 和 param分区两个合在一起写内核里..
-----------------------------------------------------------------------------------------
static struct mtd_partition smdk_default_nand_part[] = {
        [0] = {
                .name   = "vivi",
                .size   = 0x000000060000,
                .offset = 0x000000000000,
        },
        [2] = {
                .name   = "kernel",
                .offset = 0x000000060000,
                .size   =  0x000000260000,
        },
        [3] = {

                .offset = 0x000000260000,
                .size   = 0x000040260000,
        },
};
---------------------------------------------------------------
这样子写mtd分区竟然能行...而且还通过了..
这让我很不理解..

问题来了...不是说mtd分区信息不是应该和vivi一样么?
第二..parma分区有什么作用捏?
