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

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。

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。
作者: teddy    时间: 2015-7-27 15:10
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。
