For example, ITM can be used to redirect printf output to a console view in the debugger. The Instrumentation Trace Macro cell ITM enables applications to write arbitrary data to the SWO pin, which can then be interpreted and visualized in the debugger in various ways. While this imposes minor limitations on what can be done, it is also true that SWV and ITM, used with care, are capable of providing very powerful debug information that in some cases are otherwise unobtainable information without very expensive debug hardware.
The reason is that Cortex-M microcontrollers are designed to meet aggressive cost targets. In addition, trace data makes its way to the SWO via internal buffers which are limited in depth.

It is possible in certain circumstances that all of the data may not be received by the front end debugging software on the PC.

As more types of trace data are enabled for transmission, the more trace packages are needed to be sent from the CPU to the PC debugger.
The developer can configure SWV in many different ways, to make it emit various combinations of information, e. Based on this trace data, modern debuggers can provide developers with a wealth of advanced debugger capabilities.

Serial Wire Viewer provides advanced system analysis and real-time tracing without the need to halt the processor to extract certain types of debug information. The SWD port itself does not provide for real-time tracing.
It replaces the JTAG connector with a 2-pin interface one clock pin and one bi-directional data pin. Their respective roles will be explained below. It also outlines how advanced debuggers can exploit the SWV and ITM technology to deliver powerful debug capabilities to developers.

This is made possible by the internal architecture of the devices, and does not require software support such as low priority daemons or monitor code that must linked with the application.

Serial Wire Viewer SWV provides real-time event and memory access tracing with little- or no processor overhead while the application executes at full speed. With SWV, it is now possible to have greater visibility into the dynamics of complex real-time embedded applications than ever before. This is the first blog post in the article series several more will come in the next couple of weeks. All files which you are "intended" to be able to modify such as main.While talking to our TrueSTUDIO customers, as well as many other Cortex-M developers, it has become clear to me that many developers are not aware of the powerful system analysis and debugging mechanisms available in Cortex-M devices.īy better utilizing the capabilities that are already in their possession, embedded developers could easily become a lot more efficient in their debugging efforts. This may sound tedious, but it also a way of making sure that you are in control of which changes are introduced into your project code rather than STM32CubeMX. If the version control system allows storing the metadata outside the project root folder this is an even better option. Important to consider is however that if the version control metadata is stored inside the project folder which would be the default with for example git, then the revision history is not backed-up and safe until you have pushed it to a remote - which as a minimum should be outside the project folder.
The obvious solution to back-up the project files and the code is of course to version control using some version control software. Eclipse plug-in version has the benefit of giving you one IDE with all tools integrated - this option appeal to some people.Īll-in-all our recommendation would be to use the stand-alone version. So which version should you use? This question does not have one simple answer. STM32CubeMX is a graphical tool that allows a very easy configuration of STM32 microcontrollers and the generation of the corresponding initialization C code through a step-by-step process.īut the tool helps you download the latest version automatically. This is simply put a zip-file that provides drivers, stacks and example project for a specific STM32 device series. The two most important components of the STM32 Ecosystem are. But first a table of content and some concept definition and orientation This ecosystem of tools is continuously growing and incorporating more tools, drivers, stacks and example projects. Do not miss the FAQ at the end which are the most common issues that first-time users run into. Where to start? There is plenty of information available on that topic on st.
