Add them on the live expressions tab. It's buggy on restarts, you usually have to re-enter them when you re-run, but it works.

    Thank you for the answer.

    I didn't understand the meaning of this.

    Excuse me. How should I set it up?

    The "Live Expressions" tab is two tabs to the right of the "Expressions" tab on your last screenshot.

    I think it's mean.

    Is it right??

    But It isn't real time variables...

    It has a fixed value.

    I toggled it every second by program.

    Works for me. Make sure your variable exists and the compiler isn't optimizing it out.

    I used ST-LINK/V2.

    Target mcu is STM32G030C8T.​

    ​

    VDD

    GND

    SWCLK

    SWDIO

    Debug Setting.

    I programmed the variable to increase by 1 every second.

    However, after changing from the initial value 0 to 1, nothing has changed.

    Maybe the G0 doesn't support live expressions. I don't have a board to test it with. Not sure.
