为什么我在uboot下格式化nand flash后选择从nor flash启动会出错？

我试着在uboot下面格式化nand flash,之后我选择从nor flash启动。就出现如下错误

NAND read: device 0 offset 0x60000, size 0x200000

reading NAND page at offset 0x60000 failed
Could not read entire image due to bad blocks
2097152 bytes read: ERROR
## Booting image at 30007fc0 ...
Bad Magic Number


然后直接进入menu选择，好像不能自动引导内核了，我重新刷整个系统。刷成功之后启动还是这样，这是为什么？

我之前就是format nand flash了，从0到0x04000000,然后从nor flash启动也不行了，而后利用nor里面的uboot烧写了重新烧写了整个系统，还是这样，，我不太清楚这个fformat nand flash是什么用途，不是擦除我指定的地址的东西吗？

我自己弄好了，应该就是nand flash有坏块导致的，我把nand flash先nand srcub一下，然后把里面kernel分区erase，在重新烧写kernel image就可以启动了。谢谢了
