How to check CPU Usage

leekate-b45752 — Fri, 09 Mar 2018 15:51:22 GMT

Hello,

In S32 DS for ARM, how can I check the CPU usage or calculate MIPS?

Also, is there any checking tool about the stack memory usage according to the functions in the SW?

Best regards,

Kate Lee

Hi Kate,

I assume you are using GCC in S32DS.

I found a nice article by Erich related to the static stack usage estimation using gcc tools:

If you are using FreeRTOS you can watch dynamic stack usage of each task in the Task List:

For the bareboard setup we don't offer any sophisticated tool for stack usage/CPU usage.
