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

是从nand启动的。运行一段时间就会出现上述的现象。

你的程序是否用到EMIFA，跟nand可能会冲突的

: V- X" T6 y  H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

% T% }  k/ {/ p/ j) s( p# ~% UEMIFA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
