Error during Debug in MPC5777C

sourabhjain · ‎11-13-2017

Hi i am trying to debug a code in MPC5777C so during debug the code stuck at particular line and showing an error like this

Program received signal SIGINT, Interrupt.
0x00c10010 in IVOR1_Vector ()
No source available for "IVOR1_Vector() at 0xc10010"

but when i comment the line where code stuck then the code debug properly and generate result

so can you please find what is this error for and why my code stuck ?

First of all focus on what is the source of IVOR1. (Critical or NMI interrupt?)

Do you have programed IVOR1 handler?

When you step assembly in the code do you see correct instruction execution?

here is my code at the end where i try to update duty cycle from 11% to 40% in this the line which is bold type where my code stuck and when i stop the debug then this type of error come given below.

Program received signal SIGINT, Interrupt.
0x00c10010 in IVOR1_Vector ()
No source available for "IVOR1_Vector() at 0xc10010"

if i comment the line in bold then the loop run fine and code execute successfully.

i also try to update etpu_set.h written below where i comment the additional zero which are shown here in bold letter because of this some times code run and sometimes do not.

Hi,

I am afraid that we need more details if you want us to help you.

Compiler? Debugger?

Is this your code? etc..

If you step it in debugger assembly do you see proper instruction execution? Are you core registers loaded correctly?

Give us more details then just your failing line.

Peter
