How many breakpoints can I place?

[etolocka]

Hi

I´m using CW 5.1 with S08GT60.

I place a breakpoint in two different C instructions. The program stops in the first, then I press F5 but the second breakpoint is ignored. Why? I have only one hardware breakpoint available?

Thankfully,
Ernesto.

Hello

Basically number of breakpoints available depends on the number of hardware breakpoint available on the chip.

In case there is not enough resource (HW breakpoints registers) available to set all breakpoint, the debugger would report that right away. It will not ignore the breakpoint. It will just tell you there are

too many breakpoints defined in the application.

Are you sure there is code generated for the second location where you tried to set a Breakpoint?

To check that:

  - Start the IDE

  - Set your breakpoints as usual

  - Select Source -> Marks

There will be marks in the Source window, at each location where a breakpoint can be set.

Is there a mark in front of the instruction where you try to set the breakpoint?

Are you sure the instruction is executed?

Thank you for your response, CrasyCat

GT60 has only one HW breakpoint, plus two comparators (triggers A and B)  in the DBG module.

Yes, "marks" are activated and every instruction I tried to place the breakpoint has the red mark.

Another test I made: I placed in the code the following:

Breakpoint 1
Breakpoint 2
Trigger A
Breakpoint 3
Trigger B

(the instructions are not contiguous)

Program stops in Breakpoint 1, Trigger A and B. The other breakpoints are ignored.

I understand that I can place only one breakpoint because the microcontroller has only one HW breakpoint, but, why I do not receive any warning message from the debugger when I place additional breakpoints?

Thankfully,
Ernesto.
