* Function prepares SWO on MCU for output data to debugger If you want disable debug mode (when in completely production mode), you can do it with define in defines.h file: They will be in your code, but will not affect to size/speed of your code. If you enable this define and set debug to 0, then all functions becomes defines with empty content and compiler will just throw them out. Second option, is to set one define I’ve made in library. One option will be to everywhere in your project delete lines when you display something to SWO. But then, you want to completely disable this debugging mode. If you select: START -> Device and Printer You must see something like below.

The PC see the NUCLEO-F401RE as a Virtual COM Port. When you are in debug mode and want to display some data, you can do with print function in my library. A minimum debug using pc.printf Up to now is not present a serious debug tool in Mbed, the only possibility that you have is to use the pc.printf orprintf that send a message (text, variable, etc) via USB port to the PC. On initialize, SWO peripheral is enabled on pin PB3. Program will be in real time speed and you will watch your data on SWO pin in Keil uVisionĬlock for programming, necessary if you want to program/debug MCUĭata input and output, necessary if you want to program/debug MCUĭata pin from MCU for trace view (Serial Wire Viewer), optional and recommended To start program in real time, press F5.Make sure, you have enabled option “Debug information” under “Options for Target” -> “Output”.Go to application, compile it and press “Start/Stop Debug Session” (Red button).In “Trace” tab make sure you have settings the same as on picture below.Click on “Settings”, new window will open.

Use STM32 ST-Link Utility to update to newest version.Select your debugger, if you are working with STM32F4-Discovery, select ST-Link.Open “Options for Target” -> “Debug” tab.There are also a wide range of development environments including IAR EWARM, Keil MDK-ARM, mbed and GCC/LLVM-based IDEs. First is that you need to specify real CPU clock so trace will be synchronous (like baudrate in USART). Nucleo boards allow anyone to try out new ideas and to quickly create prototypes and integrate an ST-Link debugger/programmer, so there is no need for a separate probe. To get this to work, you have to make sure for some things. In production (non debug) mode, SWV will not work. This feature is enabled only when MCU is in debug mode. If you are using external programmer/debugger (Keil ULINK2, Keil ULINK Pro, Segger J-Link, etc), then you should check if they have SWO option, but every serious debugger should have this! Some boards (like F429-Discovery) needs solder bridge if you want to enable connection. ST-Link on STM32 boards has this input, if SWO from MCU is connected to ST-Link by default, check schematics.

This is called SWV (Serial Wire Viewer) using SWO ( Serial Wire Output) output.

Full SWD also enables you to output something from MCU which debugging. For programming, only clock and data lines are required. All STM32 boards, which have ST-Link on board, uses this option. STM32F4 has SWD ( Serial Wire Debug) option for programming/debugging. This can be used instead of one USART available in STM32F4 to display data to user when something is going wrong and you want use debug.

USB VBUS or external source(3.All Cortex-M4 devices have feature to output different data for debugging.

The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as direct access to mbed online resources. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features.
