这些是编译时出现的警告提示。不知道这个跟这个unknown nand有木有关系呢？

复制代码
  1.         tmp = id_data[1];                /* Device ID */
  2.         for (j = 0; nand_flash_ids[j].name != NULL; j++) {
  3.             if (tmp == nand_flash_ids[j].id) {
  4.                 type = &nand_flash_ids[j];
  5.                 break;
  6.             }
  7.         }
  9.         if (!type) {
  10.             printk(KERN_ERR "Unknown NAND Device.\n");
  11.             goto exit_error;
  12.         }

很明显，这是因为从NAND Flash上读到的ID值(tmp)在代码里预置的ID值表(nand_flash_ids[j].id)里匹配不到造成的错误。你试过把tmp和nand_flash_ids[j].id打印出来看看吗？
"If you have an apple and I have an apple and we exchange apples, then you and I will
still each have one apple. But if you have an idea and I have an idea and we exchange
these ideas, then each of us will have two ideas."

错误提示一样吗、
因为我的板子在是友善的基础上进行了修改，不能用友善的启动代码，我的uboot移植都无法驱动K9GBG08U0A所以 也就没有做linux的移植
