write yaffs2 image to nand for dm365
我们知道， dm365的rbl 对 nand flash的支持比较特别，和uboot以及内核的不相同，需要打补丁，因此导致写oob的fs需要特别的操作，
特别是针对硬件开启ecc的内核和uboot（本人就是）
起初，不管怎么改nandwrite 和mkyaffs2image（这个东东很难下载到！！本人实在是无奈，从官网下载到了，和邮件列表上回复的时间一致的版本，方便打补丁嘛）
分析oob
通过挂载yaffs2，拷贝写文件：

对比分析：OOB 0-1 未使用（为FF）
OOB
OOB
OOB 0-5 未使用（为FF）
OOB 中未使用部分 2+6 = 8bytes，使用部分 24 - 8 = 16 bytes
(参见dm365 中ecc的部分分析)
分析工具mkyaffs2image：
mkyaffs2image.c中写oob部分：
typedef struct {
yaffs_PackedTags2TagsPart t;
yaffs_ECCOther ecc;
}yaffs_PackedTags2;
typedef struct {
unsigned sequenceNumber;
unsigned objectId;
unsigned chunkId;
unsigned byteCount;
} yaffs_PackedTags2TagsPart;
yaffs_PackedTags2TagsPart 大小为 4×4=16 bytes
yaffs_ECCOther 不需要写入，因为内核自己做 hw ecc（硬件ECC）.
和上面一致.修改部分：下载，打补丁，用法。
（注意http://www.aleph1.co.uk/gitweb?p=yaffs2.git;a=shortlog;pg=5这里的shortlog 需要接近于补丁的时间：
Author: Vu Tran
Date: 2007-09-12 22:00 +800
To: yaffs
Subject: [Yaffs] Fix for mkyaffs2image utility
Date: 2007-09-12 22:00 +800
To: yaffs
Subject: [Yaffs] Fix for mkyaffs2image utility
见此处，选中，某个时间段，点击snapshot即可。由于我们只只适用里面的utils，因此版本估计影响不大）
打过补丁后，另外需要修改（应该不修改也没关系？）
memcpy(&(oobData[oob_tags_pos]),&pt,sizeof(yaffs_PackedTags2));
为
memcpy(&(oobData[oob_tags_pos]),&pt, 16);//注意我们只写16字节。
注意此补丁的作者（见patch address url） 建议使用下面的参数 来烧写img
./nandwrite -a -o -q /dev/mtd6 img/config.img
编译mtd-utils
此工具真的很难整。。
下载需要的依赖
zlib-1.2.5.tar.gz lzo-2.03.tar.gz uuid-1.6.2.tar.gz
解压
cd /opt/utils/uuid-1.6.2
./configure --host=arm-linux prefix=/opt/utils/uuid-1.6.2/build CC=arm-none-linux-gnueabi-gcc ac_cv_va_copy=no
make && make install
cd /opt/utils/lzo-2.03
CC=arm-none-linux-gnueabi-gcc ./configure --host=arm-linux --prefix=/opt/utils/lzo-2.03/build
make && make install
cd zlib-1.2.5
prefix=./build CC=arm-none-linux-gnueabi-gcc ./configure
make && make install
注解 makefile中的 BINS += mkfs.ubifs/mkfs.ubifs ，不然这个工具编译报错（主要是有2个函数调用链接报错）。。如果有人知道怎么修改。。请告知。
修改Makefile ,在 VERSION = 1.4.5下面（开头）添加
#################
#mike add for ti 3515
CROSS := arm-none-linux-gnueabi-
#bug !
BUILDDIR := $(CURDIR)
ZLIB_DIR := /opt/utils/zlib-1.2.5/build
LZO_DIR := /opt/utils/lzo-2.03/build
UUID_DIR := /opt/utils/uuid-1.6.2/build
DESTDIR := /opt/utils/mtd-utils/build
#addend
修改
LDLIBS += -L$(ZLIB_DIR)/lib -L$(LZO_DIR)/lib -L$(UUID_DIR)/lib
添加库路径
然后编译
cd /opt/utils/mtd-utils
make WITHOUT_XATTR=1
如出错，请修改Makefile以链接进正确的库
最后拷贝nandwrite nanddump mtd_debug 和
libuuid.so libuuid.so.16 libuuid.so.16.0.22
到目标板，添加库路径
export LD_LIBRARY_PATH=/home/workspace/mtd-utils/lib:$LD_LIBRARY_PATH
即可运行这些工具。
针对DM365的补丁
继续修改（上述补丁只适合于未打补丁的内核，不针对打过补丁的内核(使用于dm365)）：
注解关于 MEMSETOOBSEL 、 MEMGETOOBSEL 的ioctl 调用
（不适用于新版本内核。或者说在本人系统上会报错 。。。本人内核版本2.6.32.17）
修改写OOB部分的代码：注解部分
if (!noecc) {
int i, start, len;
int tags_pos = 0;
/*
* We use autoplacement and have the oobinfo with the autoplacement
* information from the kernel available
*
* Modified to support out of order oobfree segments,
* such as the layout used by diskonchip.c
*/
// if (!oobinfochanged && (old_oobinfo.useecc == MTD_NANDECC_AUTOPLACE)) {
// for (i = 0; old_oobinfo.oobfree[i][1]; i++) {
// /* Set the reserved bytes to 0xff */
// start = old_oobinfo.oobfree[i][0];
// len = old_oobinfo.oobfree[i][1];
// if (rawoob)
// memcpy(oobbuf + start,
// oobreadbuf + start, len);
// else
// memcpy(oobbuf + start,
// oobreadbuf + tags_pos, len);
// tags_pos += len;
// }
// } else {
// /* Set at least the ecc byte positions to 0xff */
// start = old_oobinfo.eccbytes;
// len = mtd.oob_size - start;
// memcpy(oobbuf + start,
// oobreadbuf + start,
// len);
// }
///新添加部分，见前面的分析
memcpy(oobbuf + 2, oobreadbuf, 4);
memcpy(oobbuf + 16, oobreadbuf+4, 6);
memcpy(oobbuf + 32, oobreadbuf+10, 6);
}
yaffs oob 也要修改
static struct nand_oobinfo yaffs_oobinfo = {
.useecc = MTD_NANDECC_PLACE,
// .eccbytes = 6,
// .eccpos = { 8, 9, 10, 13, 14, 15}
.eccbytes = 40,
.eccpos = {6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
22, 23, 24, 25, 26, 27, 28, 29, 30, 31,
38, 39, 40, 41, 42, 43, 44, 45, 46, 47,
54, 55, 56, 57, 58, 59, 60, 61, 62, 63,
},
};
main 函数的oob也要修改
int main(int argc, char * const argv[])
{
//...
struct nand_oobinfo old_oobinfo =
{
.oobfree = {{2, 4}, {16, 6}, {32, 6}, {48, 6}},
};

真对上述修改，写入命令变为：
mkyaffs2image DIR app.img
flash_eraseall /dev/mtd5
./nandwriteyaffs -o /dev/mtd5 img/app.img
经过多次修改，下面的二进制都静态链接到.a库而不需要拷贝.so了。。。
nanddump mtd_debug nandwrite
终于完善了。
