live expressions bug

ali rostami · ‎2024-03-06

I use STM32CubeIDE version 1.14.1. When I'm in debug mode, the Values in the "Live Expressions" window are weird and wrong.

However, I found out that after editing and putting a random value in one of the fields, it will be fixed.

ASAP, huh? Is there a timeline associated with that, or does ASAP mean the same as "whenever we get to it, which may not be ever"?

Live Expressions have literally never worked well. Would love to see it fixed.

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.

Same problem still ongoing, is there any sloution? Without debuger all data is fine for exampl e with communication on ethernet at real world. But when i try to observe the data from live expressions, almost all data wrong. Sometimes it turn true but not always.

I noticed the same problem with IDE 1.19.0 and with a STM32H750XBH6, if I switched to a STM32H753 and it didn't happen, back to the first micro and it did. Only way to fix it is mess with one of the variables and it seems to fix things.

It's so weird when it happens, it's like the live expressions is reading a memory location that's 1 byte shifted.
