Default ISR

[Nayan123]

Hii,

I am trying to run an simple led blinking program on FS32K144HAT0MLL Microcontroller which comes in S32 series.

But my application gets stuck in Default_ISR.

Previoulsy I was using FS32K144UAT0VLL, difference is the operating clock frequency and operating temperature range.

PFA of debug view.

Hi Nayan123,

Previous FS32K144UAT0VLL is 112MHz, and now FS32K144HAT0MLL is 80MHz. Did you change the clock frequency to 80MHz? 

According to debug window, seems that PINS_Init() caused hardfault Default_ISR. Before the codes access the PINS_Init related registers, did the clock gate enabled? for example: when you access PORT_PCRn check the CGC bit in PCC register.

Best Regards,
Robin

Hii Robin_Shen,

Thank you for reaching out.

The issue is resolved by changing the crystal oscillator. Its position was incorrect.
