标题: SOS,从NAND启动，uboot加载linux 内核报 bad data crc错
使用创龙核心板加自制的底板，总线上挂接16C554串口芯片，突然出现从nand启动后u-boot加载linux内核时报 bad datacrc错误，掉电重启后可以正常3 @. E2 t( |' t4 `3 f

进系统但是SSH应用程序报ubifs读node错误，这种现象会不会是u-boot的bug, 日志文件如下:

16C554串口芯片是连接在emifa总线，nand flash也是连接emifa总线，有可能被影响了。

' P* F8 C5 x! w: t, F2 Z会是数据线影响，还是片选之间干扰，16c554 是一上电就复位的。

有没有可能EMIF哪个寄存器设置不妥当产生这种影响。

可以参考创龙的多串口模块TL16CP754，就是通过emifa扩展串口，相应的驱动源码，例程都是提供的。

( N- B, P) r( ^( |3 r. F: Y* A+ J" C! KEMIF相关配置应该是没问题的，spansion的片子在延长总线时序，增加时钟之后，UBIFS逻辑坏块试了1000次反复满规格擦写不会出现，但是某些核心板还是会出现重启后内核bad crc，一般是在更改系统里文件并reboot之后出现，这时在u-boot中reset,又正常了，但是还是会出现在" j0 z6 t; c! f. d
