What is required for live expression support

Carl_G · ‎2025-04-08

I am trying to use live expression on an STM32G0 with an Stlink V3minnie. It's not allowing me to read any variable even once. I read that the variables need to be global. Is this true? Does this mean class variables also will not be supported but only static variables?

Thanks.

It does, indeed, say global variables:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

That worked. Even class static doesn't work but full static variables do.
