S32S Code Profiling timings

Hi,

We wanted to check if you have any code profile timings values for base drivers available? This is to do timing analysis. If Approximate estimations available also, kindly share .

Hi Neetigya,

We don't have specific code for measuring S32S247 driver timing. But it's not hard to do that for users.

When doing timing analysis, it's common to use a timer, like STM, to measure time. Compare the timer counter between the starting point and ending point.

This is the basic method for analyzing code efficiency, interrupt firing, core loading, etc.

There are timer examples in the S32S247 SDK package, you can port the code to where you want to do timing analysis.

Hi,

Thank you for the explanation. We don't have the micro controller with us yet. Is it possible to analyze without a target?

Hi,

It's possible to use an emulator to do that but I don't know if it's available for customers. Please reach out to the NXP contact (sales/FAE/disty) of your company for details.
