MKE02Z64VQH2(ke02z) interfaced with AT24C32

[rajkanyasaha]

I am using MKE02Z64VQH2(ke02z) interfaced with AT24C32. When i run my code, control goes to PE_ISR(Cpu_Interrupt) function definition. I disable all the interrupt from processor expert and again tried to run my code still same thing is happening. How to resolve? And moreover there is no requirement of interrupt in my code too.

Core 'hard faults' are still an interrupt, and end up at that 'dead end' handler in default projects.  You PROBABLY need to enable some peripheral-clock for a subsystem you are trying to use.

I don't know why a 'decent' fault-handler isn't just 'part' of all basic projects --- these come up ALL the time, and without some tools can be 'very difficult' to find.  The information you need is 'on the stack', but have fun looking THERE!  I suggest the handler pointed to here:
