Query regarding the sampling rate of BCU utility for power measurements on iMX93EVK board

[Vikas7Bal]

Hi,

I am trying to perform power measurements on the iMX93EVK board using the host based BCU utility.

I have observed that, the BCU sampling rate is fixed at 10 ms and from the BCU.pdf I came to know that "BCU operates at best sampling rate possible" and I couldn't find a way to configure the sampling rate.

So, is it possible to configure the sampling rate for BCU?

Also, in the nxp-imx/bcu git repo which is used to build the utility, I observed that, "MAX_NUMBER_OF_POWER" macro is being hardcoded to 100 which could probably be the reason for 10 ms sampling rate.

So is it possible to change it to higher values so that I can build the tool from the source code and achieve much finer sampling rate?

Hello @Vikas7Bal 

The sampling rate is hardcoded with many other code in BCU, modifing it in source code could cause other compatible issue. We don't recommend you modify it.
