  • How to prevent SystemViewer from crashing in high load situations?

    Hi,

    I have got FreeRTOS (v8.2.3), lwip (1.4.1), iperf and SystemViewer (v2.30) running on my STM32 target.

    as soon as I start a iperf session, SystemViewer stops recording. The target can handle further iperf sessions without problems.

    I have attached a record.

  • Hi,

    With high load situations a larger SystemView buffer is required.
    Setting SEGGER_SYSVIEW_RTT_BUFFER_SIZE to 4096 or 8192 should help.

    Does SystemViewer completely stop recording or does it not get any events anymore?

    Regards
    Johannes
