硬件：I.MX6D 镁光的ddr3两片
软件：linux3.0.35 + QT5.4
跑了两天后出现如下问题，终端还在打印，不过是乱码，内核还没有死，好像是挂起来了，这个问题怎么定位，怎么查啊？

楼主你好，请问你这里u-boot起来以后，kernel启动参数有设置正确么?

我觉着跟u-boot和Kernel关系不大，你想中间没有断过电源而且一开始正常的显然和这两部分问题不大，我现在在想是不是你跑QT申请了内存没有释放？

如果是同一批板子，有的可以正常跑，有的不正常，操作都一样的话，那边就应该是硬件的问题。关于设计好的板子，查的话，一般就是核对原理图PCB是否有问题，查看PCB焊接是否OK，是否有虚焊，器件是否有选错，两外就是测量电源输出。希望如上回复对你有帮助。
