ARM Version 1.6

Quick-start Tutorial

Complex These breakpoints use advanced hardware support on your target

processor, or as implemented by your simulator software.

Check your hardware characteristics, and your vendor-supplied

documentation, to determine the level of support for complex

breakpoints.

RealView Debugger provides the Set Address/Data Break/Tracepoint dialog box that

enables you to specify your breakpoint details and to define how execution continues

after the breakpoint triggers. This is described in full in the chapter describing working

with breakpoints in RealView Debugger v1.6 User Guide.

Viewing your hardware characteristics

To see your hardware support for complex breakpoints select Debug→ Complex

Breakpoints → Show Break Capabilities of HW... from the default Code window

main menu. This displays an information box describing the support available for your

target processor.

Note

If you are using the default ARMulator to simulate an ARM processor, this does not

support the use of complex breakpoints.

Actions and qualifiers

Breakpoints are also classified depending on the action taken by RealView Debugger to

trigger the breakpoint:

Unconditional

The program stops if execution reaches the specified location.

Conditional The program stops if execution reaches the specified location and one or

more predefined conditions are met. The conditions that must be satisfied

can be defined based on data values or on counters.

Setting conditional breakpoints

Use the Set Address/Data Break/Tracepoint dialog box to set a simple, conditional

breakpoint:

1. Select File → Reload Image to Target to reload the image.

2. Select File→ Open... and open the source file

dhry_2.c

so that it is displayed in

the File Editor pane.

3. Scroll through the source file

dhry_2.c

and locate the line:
