Using Tracealyzer in streaming mode with ST-Link V3

[paolog]

I'm currently testing Tracealyzer but I'm having problems in using it in streaming mode. I followed the indications in video "Visual trace diagnostics with STLINK-V3, Percepio Tracealyzer and DevAlert" (https://www.youtube.com/watch?v=rZlSuq7TySA) to setup ITM but it seems not to be working. SWV is enabled, clock is set as on target, "Shared ST_LINK" flag seems to have no effect, ITM Stimuls Port is set correclty.

- Tracealyzer 4.8
- STM32CubeIDE 1.15.1
- ST-Link V3 or ST-Link V3 Mini (same result)
- No RTOS (bare metal)
- Custom board

Once the system is set up according to the video, if I start debugging from STM32CubeIDE, starting tracing from Tracealyzer gives the error "Unable to select and reset device" (in the Tracealyzer setting window the ST-LinkID is recognized correclty). The SWV Trace Log window in STM32CubeIDE shows the activity.

If I start the trace from Tracealyzer I can't start debugging from STM32CubeIDE as it stops at the ST-Link firmware verification with the error "No ST-LINK detected".

Seems like it's not possible to access the ST-Link at the same time from the two systems.

Snapshot tracing is working instead.

Do someone has the same issue? How can it be solved?

Right, try to have two drivers in one car - same problem . :)

So use IDE/debug , OR Tracealyzer/whatever this is.

Hi @AScha.3 , thank you for your reply.

You're definitely right, watching the video more carefully I realized they show exclusive use, debugger or analyzer. :eyes:

Working as expected. :thumbs_up:
