SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

Debugger keeps optimizing my code. How to avoid it

I set the Optimizer settings to -O0.

The debugger keeps optimizing my variables. I have a code like below

function example(.....) {

double time_taken;

clock_t start_time;
some arm functions...

clock_t end_time;
time_taken = end_time - start_time;
}

I have breakpoints at multiple locations within the function and debugger doesnt show me the values of the variables and keeps optimizing them out.

What is the solution to this.?

Hi,

You can add volatile attribute. It should avoid any kind of optimization.
