Hi, My application is always stopping in

static void FaultISR(void)
{
//
// Enter an infinite loop.
//
while(1)
{
}

}

I am not getting who is interrupting. Can any one help to solve this

Then, it's your codes cause the issue. I suggest you add your codes piece by piece to verify which part causes the problem.

Hi Chen,
Please tell some alternative to solve this. This lis not returning also and even if I try comment while loop also its not coming out of loop.
At least can I know who all responsible for calling this handler

Hi Raghunandana,

This is a result of the hard fault handler (0x03 in VECPEND), you can check the HFAULTSTAT or other fault registers to see what event activate the ISR. More information is provided in the User's Guide and I recommend that you continue your debugging efforts.

Regards,
Ryan
