MicroZED profiling

jesusmgonzalez

Hi,

I'm trying to profile my ARM application, and I think almost everything is fine (number of call functions),
except number of samples and corresponding time, that are both equal to zero. Do I have to modify my code,
or Vivado's design, in order to achieve time measurements?

I followed both UG1165 and Adam Taylor's wonderful guide.

My  board is microZED 7z010, and my current Vivado version is 2015.2.

Thanks in advance!

    Hi,

    I finally obtained some samples and measurement times, but with no sense for me. For instance, in the attached image it can be seen how scu_timer_init is sampled several times (it means system can't initialize this timer for an specific sample time), but when I set up sample times above 10.000 Hz, it begins giving me information only for Xilinx functions called in the code. I wrote a dummy heavy function, and 0 ns was reported as execution time (not possible).
