  • [SOLVED] enabling tracing with JLink (not JTrace)

    Hello,

    I have the cortex-m trace ref. board and JLink EDU. I know I cant do tracing with JLink but I only want to see the signals (TCLK, TDx) on the oscilloscope. I am using the example project for the ref. board, but when I attach debugger, it says "ETM RAWTRACE is not supported by the connected emulator" and I believe (because I do not see anything on the oscilloscope) trace is not enabled. Is there a way to enable trace without a JTrace ?

    Best regards,

    Mete
  • Hello,

    Thank you for your inquiry.
    The J-Link does not have any pin tracing capabilities.
    For this a J-Trace PRO is required:
    segger.com/products/debug-probes/j-trace/

    If your target device features a trace buffer, a J-Link can be used for tracing.
    An overview of the different trace types can be found here:

    Best regards,
    Nino
