  • [ABANDONED] JLink report unknown errors when tested with STM32L552E-EV and Ozone demo project

    Hello,

    I’m learning embedded development with a J-Trace Pro and an STM32L552E-EV board. After downloading the trace demo project from the segger wiki, I try to debug it with Segger Embedded Studio and Ozone.


    Here is the board information.
    st.com/en/evaluation-tools/stm32l552e-ev.html

    Here is the demo trace project wiki.
    wiki.segger.com/Tracing_on_ST_STM32L552

    The attach is how I connect J-Trace Pro with the board.

    However, when click the debug button, the panel shows the error information:

    Disabled output of control characters

    Could you please help to figure out the problem?

    Thanks.

  • Hi,
    Thank you for your inquiry.
    We are sorry for the delay in response. We have been very busy with some pressing projects the last couple of weeks.
    Such an issue is not known to us and we are not able to reproduce it:

    Setup:
    - Ubuntu 20.04
    - Ozone V3.20e
    - J-Trace PRO Cortex-M V2

    Could you please try the following:
    - Open the J-Link Commander (JLinkExe)
    - Connect to the device
    - Send the command "erase" (without quotations).
    Does this work as expected?
    Could you please send us a J-Link Log file of both sessions, Ozone and J-Link Commander?

    Best regards,
    Fabian
