具体是这样的，用的是飞凌的开发板:
芯片 iMX6UL，
NAND flash 256M
DDR 256M
设备树 imx6ul-14x14-evk-gpmi-7.dtb 原有的u-boot+zImage+logo+dtbs+rootfs是没问题的，但是内核是3.14的。现在我想用4.1的内核来替换3.14的内核，
设备树没有变（因为开发板本身没变），
uboot没有变，
logo文件没有变，
文件系统没有变，
然后在4.1内核中编译yaffs2文件系统，然后通过 mfgtools工具烧录进去。
然后重新上电启动出现： devtmpfs: error mounting -2 这个错误。（在网上搜了好多资料，解决不了）详细打印信息如下：U-Boot 2015.04-g3989e3c (Dec 14 2017 - 19:04:37)
