Debugging
This chapter describes the debug modes of µVision and the user interface for testing applications.
Two debugging modes can be selected and configured in the dialog Options for Target — Debug:
- Use Simulator, configures the µVision Debugger as software-only product that simulates most features of a microcontroller. Developers can test and debug embedded applications before the hardware is ready. µVision simulates a wide variety of peripherals, including serial ports, external I/Os, and timers. Peripheral simulation capabilities vary depending on the device selected.
-
Use Target Debugger, like the ULINK ARM
Debugger, links µVision to a debugger adapter, which
interfaces the target system. The following debug devices are
supported:
- JTAG/SW/OCDS Adapter: which connects to on-chip debugging systems like the ARM Embedded ICE.
- Monitor: which can be integrated with user hardware or is available on many evaluation boards.
- Emulator: which connects to the MCU pins of the target hardware.
- In-System Debugger: which is part of the user application program and provides basic test functions.
Third-party tool developers can use the Keil Advanced GDI to interface µVision to their own hardware debuggers.
This chapter includes the sections:
- Using the Debugger is an introduction to simulation and program execution.
- Debug Windows and Dialogs describes the debugging features and interfaces.
- Expressions can be used in debug commands.
- Cortex-M Code and Data Trace commands, expressions, intrinsics, limitations, and use case descriptions for debugging with tracepoints.
- Tips and Tricks describe advanced techniques for a better understanding of the debugger capabilities.
