I am trying to do a very simple task but yet I am completely lost. I have a zedboard and I am able to program both ARM cores as well as the PL portion. That's working fine.
What I need is to enable the trace in one of the cores and see what happens to my software. That should be very simple, right? Notice that I am not trying to actually debug, I am just trying to make sure trace data is collected.
How should I proceed? Can I 'drive' the coresight functionalities in a zedboard design? How?
Hi snpagliarini,
Have you taken a look at our "Debugging ARM Processor Systems" course on our Training and Videos page?

You should be able to enable Coresight functionality on the PS, however I think you are asking about how to retrieve the trace buffer data out of the Embedded Trace Buffer. AFAIK, this is not something that is currently supported by Xilinx SDK but it is currently supported by the ARM DS-5 and DSTREAM tools. Take a look at this ARM diagram to see the relationship between all of these components.
By using DSTREAM with DS-5, you can gain access to the ETB through the APB Debug Bus. The ARM tools know how to accomplish this accessing these interfaces through the ARM DSP of the Cortex-A9 MPCore complex on Zynq.
