操作如下，问题依旧：
1，升级norflash的uboot
2，格式化nandflash
3，按照说明升级uboot,**,kernel,filesystem，升级filesystem打印如下：

下面是格式化时候的打印：
NAND scrub: device 0 whole chip
Warning: scrub option will erase all factory set bad blocks!
      There is no reliable way to recover them.
      Use this command only for testing purposes if you
      are sure of what you are doing!

Really scrub this NAND flash? <y/N> : y
