How to enable Tracing in STM32Cube

[Iknig.1]

Hello,

I am trying to get tracing working and when i start the debugger this window pops up saying "Tracing is not supported".

Any one have any idea what it means as i can't find any reference to it.

I have a STM32F411CEU6, watched many how videos and configured everything.

I have STLINKV3MINI with latest update, Cube is Version 1.6.

Turned on all the features I need to but Tracing I guess won't run as somewhere/how i have not enabled something.

I have added SWO wire to the the B3 pin/STLINKV3MINI and can see it streaming data on my scope

Any ideas please as i have spent five days trying to get this to work =)

Many thanks in advance imk

Not sure what exactly you want to trace, but check out the SWV Views and app note AN4989 "STM32 microcontroller debug toolbox" to get an idea what's possible.

Hello KnarfB and many thanks for the reply.

I am trying to do a "SWV Data Trace Timeline Graph " tracing of a variable in the main loop.

Same as in this ST video https://www.youtube.com/watch?v=eumKLXNlM0U.

But in five days of trying i have been unable to get the graphic or data traces to show and results.

The Live Expression of the variables works as expected, but nothing from the SWV trace.

I think i have found a bug in this Three Week old 1.6 version of Cube or STLINKV3 both of which are new.

As all the video of previous versions with STLINKV2 seem to work.

So not sure what to do, maybe order up a STLINKV2 and install STM32CubeIDE 1.51

Have you got it working and what hard/software versions please?

Many thanks Ian

Hi,

I checked my setup today with STM32CubeIDE Version: 1.6.0 Build: 9614_20210223_1703 (UTC) and two Nucleo boards: F446RE (ST-LINKV2) G431RE (ST-LINKV3). No external ST-LINK though.

No issues, both worked as expected. The TrueStudio video is more detailed and applies to CubeIDE as well: https://youtu.be/XhBiDykSS4I. Double check that the core clock in Debug Configuration and SWV Views match. You may also try with low(er) SWO clock to rule out electrical issues.

STM32CubeProgrammer also supports SWV ITM_SendChar (printf redirection) and you might use that as a somehow independend check.

Hello KnarfB and many thanks for the reply,

Noted that it works for you and i am most grateful as this is some assurance that it does work in 1.6 so maybe my STLINKV3 (I don't think so)

However I have posted this to another forum and someone on that forum has downloaded my project and found that it does NOT work in V1.6

However when they create a project themselves the trace function works in v1.6.

Hence there is something wrong with my project, the problem is what.

I have already watched the video you sent me (many thanks) and about another dozen videos and have regenerated this project COUNTLESS times.

So i am wondering if multiple regeneration have messed up the project.

BTW what should i be setting up in .IOC SYS Mode and Configuration please as i get a red bar warning.

Again many thanks for the help imk

Hello KnarfB and many thanks for the help.

So someone on another forum has tried my project and got it to start tracing by changing the port to 61235

So i have changed my port to 61235 and it works 🙂

However look at the output from the Debug session startup, it has both 61234 and 61235 port startup requests.

Many thanks Ian

Hi Ian,

glad you found it.

The red bar warning only means that you cannot activate that feature (wakeup-pin) because the resources are already allocated elsewhere. Hovering with the mouse over the bar should reveal a more detailed explanation.
