Hey!
Found this demo pretty useful to help me play around with my ST B-L475E-IOT01A Discovery. The only issue I came across was that running the debug with the current platformio.ini example yields the following error for the SWO pin:
Also, note the deprecated warnings. I managed to fix these by using the syntax recommended in the official docs.
I changed the platformio.ini to comply with the recommended syntax and, at least on my end, I am not getting any errors or warnings. I can successfully observe the ITM trace via the
swo_parser.pyscript after starting the debug session with the correct trace clock value. Unfortunately, the SWO pin frequency is still required even though the docs mention that it can be omitted for the driver to pick up the frequency.The TPIU enable command also must follow the
itm ports on, otherwise the TRACE_IOEN will remain 0 and there will be no trace pins assigned.
