Is there any other option to see maximum stack usage of a program?</P> Mon, 18 Dec 2023 06:38:25 GMT https://community.nxp.com/t5/S32K/maximum-stack-usage/m-p/1776075#M29695 sanjay645 2023-12-18T06:38:25Z https://community.nxp.com/t5/S32K/maximum-stack-usage/m-p/1798625#M31269 <P>Hi,&nbsp;</P> <P>I'm not sure what's your compiler - for gcc you can use -fstack-usage option to get used stack for each function.
