标题: omapl138Linux系统挂载ubifs经常报错
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( {8 \7 q; u# A! Z

是从nand启动还是SD卡启动的

你的程序是否用到EMIFA，跟nand可能会冲突的

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

' {4 }8 w% m, q0 j9 w+ b& g, GEMIFA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
