求助，IMX6，接上MMPF0100的I2C后导致内核访问错误虚拟地址.....

小蒋-2041760 · 发表于 2016-2-16 10:16:45

公司自己设计的板子，参照的是SPF-27516_C4，芯片采用的是MCIMX6D6AVT10AC，从SD卡启动，U-Boot 2009.08，Linux version 3.0.35。不过遇到一个非常严重的问题，卡在这里很久了，一直找不到原因。
问题具体描述如下：
   现在一共调试了四块电路板，四块电路板电路均相同，情况分别如下：第①块电路板，PCB制板、焊接及供货与其他三块不同，且优于其他三块；其他三块电路板为同一个批次，都进行过高低温存储（高温50℃，低温-20℃，存储20小时）。
   第①块电路板，所有电压和功能正常，不赘述。
   第②块电路板，所有电压正常，开机后进入主界面后，左右滑动主界面，不会导致卡死，且从主界面上进入主界面上的应用时，一般不卡死，在应用程序界面时，出现过卡死情况（随机），一旦卡死就打印Unable to handle kernel NULL pointer dereference at virtual address ....之类的信息（打印信息附在最后面）。
   第③块电路板，所有电压正常，开机过程中随机卡死，卡死后打印信息基本同第②块，开机不卡死的话，进入桌面后，按电源键使其在休眠和唤醒状态中不停切换，必定卡死，卡死后打印Unable to handle kernel NULL pointer dereference at virtual address ....之类的信息。
   第④块电路板，所有电压正常，能正常开机，能在桌面点home键，能进入应用，WM8962工作正常，但也会出现卡死情况。打印Unable to handle kernel NULL pointer dereference at virtual address ....
现在做了以下调试：
   （1）检查核对过硬件电路，现目前未发现有焊接错误的地方。
   （2）检查过各主要时钟，几块板子的时钟基本一致。
   （3）取下过触摸屏、显示屏测试，基本可以排除是触摸屏、显示屏导致死机。
   （4）更换过DDR，并进行过DDR压力测试，压力测试通过。
   （5）更换过CPU，故障依然存在。
   （6）检查过网口，能够ping通。
   （7）更换过PMIC（MMPF0100F0EP）,问题依然存在。
现在掌握的最新调试结果是：断开PMIC（MMPF0100F0EP）的I2C后三块电路板均能稳定工作，不再出现卡死打印Unable to handle kernel NULL pointer dereference at virtual address ....之类的信息，但WM8962不能正常工作了，WM8962使用的是I2C1,PMIC使用的是I2C2。
希望得到解决的问题是：搞清IMX6与MMPF0100F0EP的工作原理（过程/关系），找到CPU因为访问错误虚拟地址而卡死的原因，以及为何断开PMIC的I2C后系统就能稳定工作了，但为何会导致WM8962不能正常工作。

关于问题的描述可能不够具体，待后续补充，如果有遇到这类问题的朋友，希望给出一些指导。
