  • [SOLVED] SystemView's bugs

    1.The TimeStamp have possible to overrange:
    Could you add these code to detect?
    SEGGER_SYSVIEW.C
    _TrySendOverflowPacket(void):
    U32 Delta;
    ......
    TimeStamp = SEGGER_SYSVIEW_GET_TIMESTAMP();
    +if(_SYSVIEW_Globals.LastTxTimeStamp > TimeStamp)
    +{
    + Delta = 0xffffffff - _SYSVIEW_Globals.LastTxTimeStamp + TimeStamp;
    +}
    +else
    +{
    + Delta = TimeStamp - _SYSVIEW_Globals.LastTxTimeStamp ;
    +}
    ......

    _SendPacket():
    ......
    TimeStamp = SEGGER_SYSVIEW_GET_TIMESTAMP();
    +if(_SYSVIEW_Globals.LastTxTimeStamp > TimeStamp)
    +{
    + Delta = 0xffffffff - _SYSVIEW_Globals.LastTxTimeStamp + TimeStamp;
    +}
    +else
    +{
    + Delta = TimeStamp - _SYSVIEW_Globals.LastTxTimeStamp ;
    +}
    ......

    2.When we set the SEGGER_SYSVIEW_POST_MORTEM_MODE = 1
    and then try to build.
    We will get the error:
    can't find the _HandleIncomingPacket();

    Could we fix it like these:
    SEGGER_SYSVIEW_IsStarted():
    +#if(SEGGER_SYSVIEW_POST_MORTEM_MODE != 1)
    if(SEGGER_RTT_HASDATA(CHANNEL_ID_DOWN))
    {
    ......
    }
    +#endif
  • Hello,

    Thank you for your inquiry.
    1: Will be fixed in a future SystemView source release.
    2: Is not reproducible with the currently available SystemView sources: segger.com/downloads/jlink/systemview_target_src
    Which version are you using?

    If the LGPL license will protect the sample.c and config.c under SystemView/Sample and SystemView/Config doc?
    You can find the licensing terms in the files headers.
