发现一个问题，当运行void uffs_setup_storage(
    struct uffs_StorageAttrSt *attr,
    struct rt_mtd_nand_device * nand)
{
	rt_memset(attr, 0, sizeof(struct uffs_StorageAttrSt));

//	attr->total_blocks = nand->end_block - nand->start_block + 1;/* no use */
	attr->page_data_size = nand->page_size;		                 /* page data size */
	attr->pages_per_block = nand->block_size / nand->page_size ; /* pages per block */
	attr->spare_size = nand->oob_size;		  	                 /* page spare size */
	attr->block_status_offs = UFFS_BLOCK_MARK_SPARE_OFFSET;      /* block status offset is 5th byte in spare */
	attr->ecc_opt = RT_CONFIG_UFFS_ECC_MODE;                     /* ecc option */
	attr->ecc_size = RT_CONFIG_UFFS_ECC_SIZE;		  	         /* ecc size */
	attr->layout_opt = RT_CONFIG_UFFS_LAYOUT;                    /* let UFFS do the spare layout */

/* initialize  _uffs_data_layout and _uffs_ecc_layout */
	rt_memcpy(attr->_uffs_data_layout, k9fxg08_data_layout, UFFS_SPARE_LAYOUT_SIZE);
	rt_memcpy(attr->_uffs_ecc_layout, k9fxg08_ecc_layout, UFFS_SPARE_LAYOUT_SIZE);

attr->data_layout = attr->_uffs_data_layout;
	attr->ecc_layout = attr->_uffs_ecc_layout;
}函数的时候，当运行完rt_memset(attr, 0, sizeof(struct uffs_StorageAttrSt));后，struct rt_mtd_nand_device * nand指向的地址竟然变了，有谁知道原因吗？应该不是线程stack小的原因吧。
