SGDMA vs. PERFORMANCE_COUNTER

My code implements SGDMA and FFT IP. It works. But, when I use PERFORMANCE_COUNTER to get some timing measurements, the output from my SGDMA/FFT comes with wrong results. It also happens if I use some "printf" in the code to display messages on the console. 

 

Is it a conflict with the interruptions? 

 

Thanks.
