How to view VECTPC on Kinetis MKL17Z256VLH4?

pcpro178 — Tue, 05 Jun 2018 14:15:21 GMT

I'm trying to debug a hard fault on a MKL17Z256VLH4, and I'm not able to see VECTPC in the register view in Kinetis. I've implemented the code in this app note in hopes of drilling down to where my hard fault is getting triggered.

Can anyone confirm if these register addresses (taken from the app note) are going to be correct for the ARM Cortex-M0+?

// Configurable Fault Status Register
// Consists of MMSR, BFSR and UFSR
_CFSR = (*((volatile unsigned long *)(0xE000ED28))) ;
// Hard Fault Status Register
_HFSR = (*((volatile unsigned long *)(0xE000ED2C))) ;
// Debug Fault Status Register
_DFSR = (*((volatile unsigned long *)(0xE000ED30))) ;
// Auxiliary Fault Status Register
_AFSR = (*((volatile unsigned long *)(0xE000ED3C))) ;
// Read the Fault Address Registers. These may not contain valid values.
// Check BFARVALID/MMARVALID to see if they are valid values
// MemManage Fault Address Register
_MMAR = (*((volatile unsigned long *)(0xE000ED34))) ;
// Bus Fault Address Register
_BFAR = (*((volatile unsigned long *)(0xE000ED38))) ;

I would recommend our expert Derek's document << "Tracking down Hard Faults" >> about Kinetis product hard fault diagnostic.

Wish it helps.

Have a great day,
Mike
