  • [SOLVED] J-Trace debugging probe and trigger condition

    I want to catch a latency problem which sometimes appear on our development board. The bug shows a defect packet on the USB-Analyzer. The analyzer has an output pin which goes high in the case of the error.

    How is it possible to trigger a breakpoint from external source?

  • Hi,
    Thank you for your inquiry.

    Such a feature is not available yet and there are currently no plans to add it.
    I will add this to the feature request list but cannot provide any timeline for it.

    To achieve this, you would have to implement this yourself.
    It might be possible to do this via a J-Link Script but no guarantee.
    The required information can be found in the ARM documentation.
    Please understand that we cannot provide any support for this.

    Does this answer your question?

    Best regards,
    Fabian

  • No, this answer doesn't help.

    We found a solution: We use a pin on our board for INPUT the signal from the USB analyzer. The pin triggers an IRQ which sets a variable to high. This variable is watched with a "Data Trigger".
  • Hi,
    Good to hear that you found a solution.

    We will close this thread now.
