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？

这是现在nor启动一上电的信息

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
