Hi there!

My timestamps are wrapping / overflowing and this confuses the SysView GUI:



I found the SystemView documentation note: "In case timestamp is not retrieved from cycle counter but from system timer, SEGGER_SYSVIEW_TickCnt must be incremented in the SysTick handler before any SYSVIEW event is generated."

I have tried to debug the SysView code to figure out what the problem is but so far the root cause has eluded me Would you mind explaining in more detail what the note in the documentation means? Any hints / tips on how to solve the problem would be much appreciated, thanks!

Full disclosure: I am trying to use Segger SysView with FreeRTOS v10.3.1 and applied the FreeRTOSV10_Core.patch by hand. I used the SEGGER_SYSVIEW_X_GetTimestamp() SysTick example code and increment the SEGGER_SYSVIEW_TickCnt variable at the start of xTaskIncrementTick() in FreeRTOS/Source/tasks.c


Thanks in advance,

Pieter

I moved the SEGGER_SYSVIEW_TickCnt variable incrementing code to the start of xPortSysTickHandler() in port.c and now my timestamping works
