Using the Debugger
Using Breakpoints And Watchpoints
Setting Breakpoints on Addresses
You can set a breakpoint on a memory address. The address must contain an opcode
(instruction fetch code). If an instruction exists at one address and the data used by the
instruction exists on the next two bytes, you must set the breakpoint on the instruction
address. If you set the breakpoint on an address containing data, the debugger ignores the
breakpoint.
To set a breakpoint on an address:
1. Load the program to debug
a. If you launched the debugger from a project in the CodeWarrior IDE, the debugger
automatically loads the program ( .abs or .elf file)
b. If the debugger does not contain the application that you want to debug:
? From the debugger main menu, select File > Load Application
? Specify the location of the executable file ( .abs or .elf file)
? Click Open — debugger loads the application you specified
2. From debugger main menu, select Run
3. Select Control Points — Controlpoints Configuration dialog opens (Figure 5.6)
Figure 5.10 Control Points Dialog Box
4. Click on Breakpoints tab
5. In Address text box, type address that contains the opcode where you want to set the
breakpoint
