Cannot set breakpoint

UtopiaTim — Sun, 24 Feb 2008 05:53:13 GMT

Hi folks,

I have an initialization routine:

gselvp(0);

gsetvp(4,3,50,14);

gselfont(&mono5_8);

These are merely function calls into an LCD driver package. Each of the commands works well

in other parts of the program.

In the debugger, I can set a breakpoint on the 1st or the 2nd function call, but cannot on the 3rd.

From what I can see, the compiler has perhaps seen a previous combination of these two calls, and

will go to that combo, rather than the individual ones in my code.

Is there an option in the compiler to not do this? I'd like to do the debugging one function at a time.

When it's all done, I could turn off that switch & let it be more efficient.

Sometimes the 'help' it's giving is a bit troublesome.

Thanks,

Tim

Which compiler are you using? Which device are you targeting?

Guessing that you use a CW for HC08 or HC12, you can try to use
the options "-onf -onb=t -onbt".
There are also some "smart sliders" which set many options at once in the pref panel.

Hi Daniel,

Thanks for the reply.

Sorry, it is the 9S08JM60, and I'm using CW 6.1.

I'll look into the -onf & -onb options.

Which options in the pref panel should I be looking for?

I've noticed that the compiler will 'reuse' routines, rather than re-generate

them. I guess I want to turn off that, & just waste memory until I go through

the final debug.

Thanks,

Tim
