omapl138Linux系统挂载ubifs经常报错

piliyouke

在使用TL138开发板，进行Linux程序测试时，经常会出现ubifs文件系统挂载失败：打印如下信息：这个时候板子再重启下有时候又好了。感觉文件系统不稳定。请问下是什么问题

你的程序是否用到EMIFA，跟nand可能会冲突的

& P' E" l7 F9 U: _5 b4 wEMIFA是硬件上的定性的东西，这个冲突我觉得CPU硬件应该会自己去解决处理。感觉不是这个冲突的问题

9 |3 E% G/ P" F程序上是用到了EMIFA，上面挂载了外扩网口还有ADC呀。但是这个总线不可能不挂接外设呀。应该有方法去避免这种冲突吧

% z. w! C& t) u4 L6 O是从nand启动还是SD卡启动的

5 S0 L  w) r4 X+ J3 ^0 I是从nand启动的。运行一段时间就会出现上述的现象。

是从nand启动还是SD卡启动的
