CW 10.3 - Step over does a step into?

bobc — Tue, 15 Jan 2013 14:05:01 GMT

Hi there,

Using Cw 10.3 on a DSC target with Multilink Universal. If I click "Step over" it actually does "Step into". Is this a bug or am I doing something wrong?

Regards

Hello,

could it be that you have many (too many for the hardware) breakpoints set? In that case you might not have enough breakpoints left for doing a step over.

Regards

Hi,

I also have seen this behavior: for me the maximum breakpoint number is 6, is there a way to increase it?

Many thanks

Teckna

The limit is in the microcontroller (number of hardware breakpoints).

You get a higher limit if you debug/run your software in RAM.

See Software and Hardware Breakpoints | MCU on Eclipse

It doesn't work even if I have no breakpoints set. Sometimes it does work, but I haven't figured out under what circumstances.

For now, I have gone back to CW 7.3 with USB TAP which is slow but reliable.

Just another thought: do you have software analysis/trace enabled in the debugger settings? That would consume on-chip debug ressources as well.

It is possible that the optimizer in lined the code, so you really can't step over it.
