TI中文支持网我用的是dm368
之前用的文件系统是jffs2格式的，现在想改成yaffs2格式的。原来想用uboot烧写，于是修改了uboot源码，但是下载不成功（我觉得是下载不成功），板子起不来，找不到文件系统。后改为用nandwrite写，是支持nandwrite的，现在的问题是写入jffs2的文件系统，板子可以起来，但是写yaffs2的文件系统，板子起不来。内核已经设置了支持yaffs2文件系统。
用的擦除及写入指令是：
flash_eraseall /dev/mtd3
nandwrite -p -s 0x20000 /dev/mtd3 rootfs.yaffs2
打印错误信息如下：

经过多次的擦除和写入后，发现flash的坏块比之前多了好多，在网上查了，按照网上的设置屏蔽掉//.ecc_mode = NAND_ECC_NONE,无果，后又还原，
static struct davinci_nand_pdata davinci_nand_data = {
.mask_chipsel = 0,
.parts = davinci_nand_partitions,
.nr_parts = ARRAY_SIZE(davinci_nand_partitions),
.ecc_mode = NAND_ECC_HW,
//.ecc_mode = NAND_ECC_NONE,
.options = NAND_USE_FLASH_BBT,
.ecc_bits = 4,
};
还请TI的工程师给些建议，卡在这一周了，方法试了很多，可能是有些地方没设置好，还请给些建议。谢谢！

分区是经过重新计算的，从打印看分区没错，
