  • [SOLVED] RTT data overlap

    Hello,

    I am trying to view my data output in RTT viewer. And after a fixed time interval, I have a data overlap in the viewer.

  • Hi,
    This looks like you are having overflows of the RTT buffer.
    This happens when the device is sending data faster than the J-Link can retrieve it and
    the following modes are selected by the MCU application:
    - SEGGER_RTT_MODE_NO_BLOCK_SKIP
    - SEGGER_RTT_MODE_NO_BLOCK_TRIM

    You can improve this situation by e.g. increase the target interface speed in the configuration dialog.
    If this does not help, and the application is not time critical, you can also change the mode to:
    SEGGER_RTT_MODE_BLOCK_IF_FIFO_FULL

    Could you please check if this improves things?

    BR
