Because the SWO trace output clock is derived from the CPU clock, the Init function needs that clock plus which SWO port number to be initialized. My recommendation is to initialize it from the application. 💡 An example project with all the sources is available on GitHub: Įxternal tools (like the Segger RTT viewer) can set up the SWO in the hardware.

In order to write debug message over SWO to the host, a small piece of code is needed. J-link-edu-connected-to-trace-port Source Code to Send Debug Messages over SWO Trace Pin SWO is part of the ARM CoreSight Debug block which usually is part of Cortex-M3, M4 and M7: There would be another encoding (Manchester encoded) which is not covered here. And this is what I’m going to show in this article. One of the most common usage is the first one: using SWO to print debug messages from the target in UART style.

Variable or memory cell change over time.

What kind of data is sent is up to the application, and there is only very little CPU processing or code needed. Up to 32 packet types (or stimulus) can be used. You can think of SWO as a kind of UART TX pin using a special format to send out data packets. SEGGER Embedded Studio Cross-platform IDE for managing, building, testing, and deploying embedded applications ST Partner Program Overview Product Details Associated ST Products Served Countries Embedded Studio is a complete, all-in-one solution for managing, building, testing, and deploying your embedded applications. Technically SWO is a single trace pin which is used to stream out data packets with a certain clock rate, derived from the CPU core clock. ARM SWOīut there is yet another thing: ARM SWO trace port as defined by ARM for Cortex-M. But works only with Segger debugging probes. There is Segger RTT which is small, fast and best of all does not need any special pins. There is USB CDC, but this requires a USB connector, a USB stack and a microcontroller capable of USB. There is semihosting, but this is very slow, depends on the debugger and toolchain/library used plus is a wast of FLASH and RAM so I don’t recommend using semihosting at all. However, on many boards the UART’s are used by the application. They accelerate the development of microcontroller- and microprocessor-based projects.As the standard text and command line interface to my target boards I’m using a normal UART/SCI. STM32CubeProgrammer provides an easy-to-use and efficient environment for reading, writing and verifying device memory through both the debug interface (JTAG and SWD) and the bootloader interface (UART and USB).Įnhanced STM32Cube tools simplify setting up MPU and MCU projects and configuring the on-chip resources. In addition to specialized versions, the versatile STM32CubeMonitor tool helps to visualize the application behavior on host devices in various form factors such as PCs, tablets, or smartphones with remote data acquisition.

STM32CubeMonitor data visualization tools enable to monitor and diagnose STM32 applications at runtime. Based on open-source solutions like Eclipse or the GNU C/C++ toolchain, this IDE includes compilation reporting features and advanced debug features. It also integrates additional features present in other tools from the ecosystem, such as the HW and SW initialization and code generation from STM32CubeMX. STM32CubeIDE is an Integrated Development Environment. This easy-to-use graphical user interface generates the initialization C-code for Cortex-M cores and generates the Linux Device Tree for Cortex-A cores. STM32CubeMX is a graphical tool used to configure any STM32 device.

Traditional integrated development environments (IDEs) with C/C++ compilers and debuggers from major 3rd-party suppliers (free versions with up to 64 Kbytes of code are available) as well as the embedded software libraries required to configure and initialize the MCU or MPU and monitor its behavior in run time. Our STM32 family of 32-bit Arm ® Cortex ® core-based microcontrollers and microprocessors are supported by a comprehensive set of software tools.
