Start debugging using the menu Debug — Start/Stop Debug Session. Depending on the options set in the dialog Options for Target — Debug, the µVision Debugger loads the application program and executes the startup code.
µVision restores the screen layout of the last debugging session. If program execution stops, µVision opens an Editor window with the source code or shows the CPU instruction in the Disassembly window. Most editor features are available in debug mode. For example, developers can use the Find command and can correct program errors.
The next executable statement is marked with a yellow arrow in the Editor and Disassembly window.
The debug mode differs from the edit mode in the following aspects:
- Debug Menu and Commands are available.
- Peripherals Menu is available.
- View Menu items are added.
- Debug Windows and Dialogs can be used.
- The project structure or tool parameters cannot be modified. All build commands are disabled.
