Trace Facility

Hi, I would like to use the trace function but I have no idea how you can save it to a file… It’s a newbie question but I hope someone will shortly point out how that works. Thanks!

It really depends on the tools you are using.  For example, if you are running FreeRTOS.org on a PC then you can simply use printfs to dump the file.  If you are using something like IAR then you can view the buffer in the memory window, then right click and select save to file (details might be a bit wrong, but something like that) and it will be sucked out through the JTAG interface.

I don’t really know where to put the trace function so that everything runs properly. Should it be called before the scheduler is started? If the buffer is saved properly there should be no problem to save it as a binary file and use the tracecon.

If you are referring to the function that starts the trace then you need to place it at the point where you want the trace to commence.  The trace only runs once, until the buffer is full.

Yes, but is for example the point right before the scheduler is started OK? I mean in vMain before vStartScheduler. Because the buffer I give to it as parameter remains unchanged during runtime when it is situated there.

It works now, thanks very much!

I searched in to FreeRTOS FAQ that we to save a binary buffer file. But how to get that file from my RAM on the development board to my PC? Please suggest anybody geek there?
