how do I eliminate auto breakpoints in interrupt functions?

checkers — Wed, 21 Nov 2012 19:28:32 GMT

I want to debug my code, not the interrupts. I set a breakpoint in the C code and press f5. The program executes to the breakpoint.

When I press f10 to step to the next C code statement, it jumps to the latest interrupt function and stops there. I cannot get to the next C statement.

Is there a setting somewhere to tell CW debugger to ignore the interrupts?

Hello

Which microcontroller are you targeting (HCS08, Coldfire, kinetis, ....)?

Which version of CodeWarrior are you using?

To retrieve that info:

- Start CodeWarrior

- Select Help -> About Freescale CodeWarrior or About CodeWarrior Development Studio

Thanks for the reply. I am new to CodeWarrior and don't really know how to find the answers on my own yet.

Hello

Per default when you are stepping the debugger will stop at the next instruction executed. If an interrupt arises, it will stop inside of the interrupt function.

You can disable that behavior in the following way:

Start the debugger the usual way
Select "Multilink/CyclonePro" > "Connect". The Connection dialog is opened.
Switch to the "Special Setup" tab
Check the box "Disable maskable ISR's when stepping"
Click OK to close the dialog.

Now PC should not enter interrupt function when you are stepping. Only non-maskable interrupts might interrupt the execution.
