Hi @Sunny ,

Can you please share the details of your compiler and IDE version which you are using.

We have provided an example to configure depth of recursive function in compiler:
Compiler: arm-none-eabi-gcc
IDE : Moduls tool box 2.3

Please open Makefile in your project directory and modify these values.

CONFIG=Custom

CXXFLAGS= --param ipa-cp-max-recursive-depth = 20

Please refer to below link for more compiler options:
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html

Configuring depth of recursive function without compiler option:

You can increment a variable for each recursive call to determine the depth and can exit the recursion once it reaches depth of recursive call.

Example: 

int recursive(int i)
{
if(i==0  || count ==20)
return i;

count++;
recursive(i-1);

}

Thanks,
Krupashankar
