In addition to ETM instruction trace of the M3/4, the M7 does offer ETM data trace. Does the M7 implement this feature? Which debuggers and trace probes do support this feature?

    can you confirm that the STM32-F7 implements data trace?

    Debugging capability purely depends on the cortex core. So I'd advise you to check out this page:

    Debugging capability purely depends on the cortex core.

    Well, as I recall, portions of the ITM, ETM and DWT are optional components in the M3/M4, so not an unreasonable question. I'd assume it has full debug/trace capabilities based on ST's prior history.

    ''Cortex®-M7 Trace Macrocell™''

    Trace tends to be rather costly, and has very narrow application.

    Now that I recall, you are right, clive1.

    Sorry for causing confusion...

    Could someone from ST please confirm if data trace is implemented or not?

    Pushed to moderation, you should seek these types of answers through regular support channels, including local ST Reps, FAE's, etc.

    Ok, but can you be a bit more specific about the exact options and capabilities chosen/implemented on ST's silicon?

    It's like saying it has an ''FPU'', if you read

    http://www.arm.com/products/processors/cortex-m/cortex-m7-processor.php

    you'd assume it supported 64-bit doubles.

    ARM Hasn't publicly posted ''

    ARM® Cortex®-M7 Technical Reference Manual (ARM DD I0489)

    '' and ST hasn't posted a Programming Manual, so precise data is hardly thick on the ground.
