In the left-hand margin of each editor tab you can find a marker bar that displays view markers associated with specific lines in the source code.

To set a breakpoint, double-click in the marker bar at the position where you want to set the breakpoint. To delete a breakpoint, double-click on the breakpoint marker.

Action context menu options

Right-click in the marker bar, or the line number column if visible, to display the action context menu for the Arm assembler editor. The options available include:

DS-5 Breakpoints menu

The following breakpoint options are available:

Toggle Breakpoint: Adds or removes a breakpoint.
Toggle Hardware Breakpoint: Sets or removes a hardware breakpoint.
Resolve Breakpoint: Resolves a pending breakpoint.
Disable Breakpoint, Enable Breakpoint: Disables or enables the selected breakpoint.
Toggle Trace Start Point: Sets or removes a trace start point.
Toggle Trace Stop Point: Sets or removes a trace stop point.
Toggle Trace Trigger Point: Starts a trace trigger point at the selected address.
Breakpoint Properties...: Displays the Breakpoint Properties dialog box for the selected breakpoint. This enables you to control breakpoint activation.

Default Breakpoint Type

The following breakpoint options are available:

DS-5 C/C++ Breakpoint: Select to use the DS-5 Debug perspective breakpoint scheme. This is the default for the DS-5 Debug perspective.

Note

The Default Breakpoint Type selected causes the top-level Toggle Breakpoint menu in this context menu and the double-click action in the left-hand ruler to toggle either CDT Breakpoints or DS-5 Breakpoints. This menu is also available from the Run menu in the main menu bar at the top of the C/C++, Debug, and DS-5 Debug perspectives.

The menu options under DS-5 Breakpoints do not honor this setting and always refer to DS-5 Breakpoints.
