Start Debugging

µVision provides several ways to debug an application. For example, developers can:

• Select commands from the Debug Menu or the Debug Toolbar.
• Use the command Run to Cursor line from the Context Menu of the window Disassembly Window.
• Enter debugger commands in the Command Window.
• Execute Debug Functions from an initialization file.
• Use most editor features. For example, correct program errors or use the Edit - Find command.

Start the Debugger

• Load Application at Startup and Run to main() determine the debugger behaviour at startup. The options are configured in the dialog Options for Target — Debug.
• µVision saves and restores the screen layout of the last debugging session.

• The button Start/Stop Debug Session starts or closes a debugging session.
• The yellow arrow marks the next instruction or high-level statement ready to be executed.

Execute Commands

• Reset the CPU with the button Reset, the menu Debug – Reset CPU, or with the command RESET typed into the Command Window.
• Halt program execution with the button Stop, the menu Debug - Stop, or press Esc while in the Command Window. When program execution is stopped, µVision opens the Editor window displaying the source code.
• Continue program execution with the button Run, the menu Debug - Run, or type GO into the Command Line.

Single-Stepping Commands

• To execute one instruction use the button Step, the menu Debug - Step, or type TSTEP into the Command Window.
• To step over the program and over function calls use the button Step Over, the menu Debug - Step Over, or enter PSTEP in the Command Window.
• To step out of the current function use the button Step Out, the menu Debug - Step Out, or enter OSTEP in the Command Window.
