How to monitor CPU/Stack/Memory

leekate-b45752 · ‎11-09-2020

Hello,

How can I check the CPU load, Stack/Memory usage on S32DS for ARM v2.2 or v3.3?

If it could be measured quantitatively, CPU load especially, is it possible to monitor during debug mode?

Best regards,

Kate Lee

Hi Kate,

it depends on app running on MCU. If you are using for example FreeRTOS, for CPU load you can use Idle task hook. Also used stack memory is available.

If it is app without OS, I'm afraid that customer needs to write his own functions for CPU load monitoring and some kind of memory management. As far as I know, there is no HW support for that on S32K1xx (assuming that question is related to this MCU).
