Hi,

I have to ask a question to you. I'm developing applications for STM32 (GCC - J-Link).
When I go in debug view, is there a way to show global variables in real time, while the microcontroller is running? For me it's an essential thing.

Thanks a lot!

Best regards,
Giulio

In general, the debugger Variables view only shows variables in the top stack frame. You can add a global variable in the Expressions view.. Can be tedious if you want to see a lot of them. You can also hover over a variable to see its value.

AFAIK this is not supported with standard GDB, therefore not supported by CDT. Some vendors have extensions for this type of stuff. Have you tried to be in touch with your vendor? If it is supported in GDB, then it could be added to CDT, a bug report/feature request with details on how GDB supports it would be the way to start: https://bugs.eclipse.org/bugs/enter_bug.cgi?product=CDT

Hi I am also having trouble seeing live variables while debugging.
See the print screen attached.
When I hover I get the same info as I do with the editor.
I can place Breakpoints at will.
The expressions window shows ERROR: Target not available
I can see how to add a value to the (x)= variables window, the buttons are grayed.
I am programing a STM32L053 USB demo board and a STM32L051xx custom board.

I have a few other issues but this is my A1.
Thanks
Kev

The Expressions view shows this error when the target is not suspended, i.e. running. It will show the variables once the target is suspended and if the variables are in scope or global.
