Generate useful stack usage report with Zephyr/nRF Connect

[zhaw-moss]

Hi community

In order to set a reasonable CONFIG_MAIN_STACK_SIZE I'd like to have a stack usage report.

I've seen the option CONFIG_STACK_USAGE. This generates an additional file for every single function which is more or less usless for me (<function>.su).

Is there a good way to find out what stack size is needed instead of just trying?

Thanks!

Take a look at the Thread Analyzer section in the Zephyr documentation. It shows how you can see the stack size usage of each thread.

The Kconfigs CONFIG_STACK_SENTINEL and CONFIG_HW_STACK_PROTECTION are also useful

Best regards,
