标注红色字体的正是出现问题的部分，启动信息如上所示。
解决办法：
重新配置内核，取消下面三个选项（红色部分）。
在Make menuconfig时:
Device Drivers ->
Memory Technology Devices (MTD) ->
不要选择下面这三个选项
<>FTL (Flash Translation Layer) support
<> NFTL (NAND Flash Translation Layer) support
<>INFTL (Inverse NAND Flash Translation Layer) support
然后保存配置并重新编译即可。修改之后的的内核启动信息如下：
