Hello,
I'm currently trying to analyze my FreeRTOS application with Percepios trace software. I'm using a TMS570 microcontroller. I get everything running and I get a nice trace using periodic tasks, but all the periods of the tasks are halved. As an example: If I have two tasks with the period of 10 ms and 250 ms, the Trace software shows a period of 5 ms and 125 ms.

I use the same way of setting the periods as in the demo code, that is:

#define SHORT_DELAY_MS( 10 / portTICK_RATE_MS )

Later, in the task, the delay is achieved with:

vTaskDelayUntil( &xNextWakeTime, SHORT_DELAY_MS );


I know that the trace port to TMS570 is unofficial, but I've looked into the port and I can't find anything wrong. Does anyone know what can be wrong, besides the trace port?

If all the times are recorded as being exactly half of the true value then I would guess that there is a mistake in the configuration somewhere, but I'm not sure where to look. Please contact Percepio support directly (go to percepio.com and follow the links for support).

Regards.

Yes, it seems like all the recored times are exactly half of the true value. I will contact them. Thanks for your reply!
