Availabilty of trace data with ST-Link debug adapter

Laszlo Vagasi

Hi,

Does the ST-Link debug adapter support logging of trace data?
I'm using a Nucleo board and according to the schematic the SWO pin on the target MCU is connected to the debug adapter, but there is no Trace Data menu item under View/Trace.

In the documentation only the ULink adapter is mentioned to be used with trace data. I did not find any information whether this feature is supported by other adapters or not.
A feature matrix could be really helpful I think.

I think I have seen trace data with other adapters earlier. Like Freescales's Freadom board or NXP's LPCXpresso, but I have to check.

In case of the ST-Link adapter there is no option for SWJ in the settings window of the adapter. Might it be the problem? May I assume that only those adapters support this feature which has SWJ option?

Thanks and regards,
Laszlo

    Hi Reinhard,

    Thanks for your quick and kind reply.
    These documents you have referenced were really helpful.

    Now it seems that the trace feature somewhat works, but I can not find what I really want to use, the Instruction Trace window.

    I can not find any menu item to activate it. Could you please give me a hint what can be the reason for this?

    I have an MDK-ARM Professional license, so I hope the problem is not license related.
    This board has an STM32F303RE MCU with CM4F and ETM.

    Thanks fro your kind help in advance.

    Best regards,
    Laszlo
