  • [ABANDONED] J-Link SWO Viewer will lost first few characters

    Hi there,

    I tried output some characters by calling ITM_SendChar(), however, the first few characters will be lost.
    I tried to monitor the SWO pin with oscilloscope, all of the characters be sent by ITM_SendChar() or printf() can be found in the SWO pin. However, looks like the J-Link SWO Viewer can’t receive and show the characters correctly

    Any comment will be appreciated.


    Thanks

  • Hi,


    can you provide us with a reproducer?
    Which target device do you use?
    Could you please provide us with the S/N of your J-Link?

    Best regards,
    Niklas
