ARM Developer Studio step over : problem

Hello

I have a problem with ARM DS 2021.2 Linux version: when I do a step over instruction in my C code, I want to immediately go to the next C program line, but in ARM DS, the step over always goes int the assembly code for 3/4 steps before going to the next C line.

How can I solve this problem ? Is this an issue with some debugger parameter ?

Best Regards

Frederic
