This sets a simple breakpoint marked by a red disc in the margin.

If you want to set a breakpoint on a symbol, right-click on the symbol to display the context menu, shown in Figure 5.3, and select Set Break On.

If you want to set a breakpoint on a multi-statement line, for example on the for... loop, right-click on the statement to display the context menu shown in Figure 5.3, and select Set Break on Statement.

Setting a breakpoint updates the Break/Tracepoints pane, if it is visible, and the Output pane shows the breakpoint command, for example:

bi \DHRY_1\ #146:3

Setting breakpoints in source-level view inserts a software instruction breakpoint by default. This is set using a BREAKINSTRUCTION command. RealView Debugger attempts to set a software breakpoint where the code is not in ROM.

If your code is in ROM, RealView Debugger sets a hardware breakpoint where one is available. An error message is displayed if no such breakpoint is available.

See Using the Break/Tracepoints pane for details on viewing breakpoints in the Break/Tracepoints pane.
