Baremetal app time measurement using HWlib seems not accurate

Hi, I'm using the Intel HWlib for measuring some steps execution time on the Arrive V SoC HPS (Arm CPU). The problem is that I'm suspecting for getting unrealistic results. The code is as follo...

HI bsp_user


Is it possible if you could share with us the results that you got for the code you shared?


Just to confirm we are aligned, for steps 2.6 and step 3.4 we are expecting an elapsed time of 9 seconds and 90 seconds respectively?

Hi JingyangTeh,

I apologies, I didn't understand what you mean.

In my code I actually do something during step 1 (2.4) and step 2 (3.2). I didn't post here what I'm doing.

the results I get are actually in microseconds.

I just wanted to ask here if the measurement logic is correct since its my first time using HWlibs to perform some calculations execution time measurements.
