K64 ivINT Hard Fault

[vnguyen]

Hi everyone,

Once in a while my program would crash and end up in the below function that belongs to the "Vectors.c" file.  Under what situation would cause a program to crash and trigger it to go to the below function.

PE_ISR(Unhandled_ivINT_Hard_Fault);
PE_ISR(Unhandled_ivINT_Hard_Fault)
{
   PE_DEBUGHALT();
}

Hi Vu Nguyen ，

  What's the kinets chip you are using? Tell me the chip partnumber.

  What's the IDE you are using?

  We highly suggest you use the SDK with the newest MCUXPresso IDE, or IAR, MDK. PE in the old IDE will be not supported now.

Kerry

Hi Kerry,

I'm using KDS version 3.2.0. The chip part number is MK64FN1M0VLL12.

Hi Vu Nguyen,

  What's the detail code you have added to cause the hardfault problems.

  As I know, if you access the module register which doesn't enable the module clock will cause the hardfault problems.

  You also can refer to the link which you already mentioned to check more details:
