Quick-start Tutorial

6. Right-click to display the Source Variable Name menu, shown in Figure 4-10 on

page4-19.

7. Select Watch from the menu. This adds the chosen variable to the Watch pane and

displays the current value, if known.

8. Click the Go button on the toolbar to execute the image.

9. Click the Stop Execution button to stop the program before it finishes.

With the processor halted, monitor changes in the variables in the Watch pane.

Depending on where you halted execution, values that changed at the last pane

update are displayed in dark blue. Values that changed at a previous pane update

are displayed in light blue.

You can remove variables from the Watch pane. Highlight the entry and press

Delete. The values list is refreshed after the entry has been removed.

4.3.3 Using breakpoints

Breakpoints are specified locations where execution should stop. The breakpoint is

triggered either by:

• execution reaching the specified address

• data values at the specified location, in the current context, changing or becoming

equal to a particular value.

Breakpoints let you suspend program execution when the program accesses specific

memory locations, variables, or functions. You can define conditions that are tested or

qualify the breakpoint to define when execution stops. This section describes:

•Breakpoint types

•Actions and qualifiers on page4-23

•Managing breakpoints on page 4-25.

Breakpoint types

RealView Debugger enables you to use different types of breakpoint when you are

debugging your image. Breakpoint types are dependent on the hardware support

provided by your debug target:

Simple These breakpoints enable you to test address-specific data values. These

breakpoints can be either hardware or software breakpoints.

Simple breakpoints are supported by all ARM processors.
