I cant see the trace in STM32

Hi,

I would like to trace the variable through SWV data trace, trace log and also I want to get the data to plot via SWV Data Trace Timeline Graph. Eventhough when I make the required setup as below, I cant get the expected trace data, could you pls help me resolve ?

 

  1. Enable serial wire viewer through debugger

  2. Add the data into data trace

3. When I resume debugging I get the following values in SWV Data Trace, SWV Trace Log and SWV Data Trace Timeline Graph respectively

I would expect to see i incrementing from 1 to max value of uint16_t that is 65535.

Thanks Rim. I am using STM32 CUBE IDE 1.14.1, my board is STMF407VG-DISC1.

I cant see the same result as yours.

First of all, I am expecting to see in watch window that is under SWV Data Trace, the value of i to increment starting from 1 to 65535. This is not the case for me. Below is the case for me.

demir_0-1713808270760.png

 

Second of all, I have no idea at all what the cycles and time is for under history(i) window. When I try to scroll cursor up, the cursor automatically pulled downwards, so I cant see the first value in the history.

I also dont understand why values in history is not incremented by 1, there is difference between values by 47 or 48. I cant understand the logic behind.

Finally, the SWV Data Trace Timeline graph. Below is what I see. I dont understand what this means actually..

Could you please comment ?

Hello @demir  and welcome to the community,


Could you please specify the mcu and CubeIDE version you are using?
I couldn't reproduce the problem with CubeIDE 1.15.0, the variable 'i' is traced with a max value of 65535.

Would make sure the SWO/PB3 is physically connected. Check if there is a Solder Bridge and it is made.

Frequency of the core in actuality, and that believed by the debugger must match.
