Problem in Release Mode

[Streamer]

I am using the STM32F302R8Tx microcontroller. I usually work in debug mode. One day, I decided to use release mode and faced a problem. I looked for a solution and then tried several methods sequentially.

1)I had tried optimizasyon

2)include my driver layer

I didn't get result.  Can you help for this problem?

I didn’t get any false evaluation in Debug mode

Mydriver  folder isn't marked as souce folder. 

Notice this folder icon looks different to SRC folder

Project setting -> C/C++ general -> Path and symbols  -> goto Source folder tab  add your folder

Simple solution: dont use "release mode" !

Detailed ...: "debug" and "release" are just names for two group of settings; 

- you can set same settings in both, then no difference - and useless to use both;

- you can set different settings, maybe have different optimizer setting, etc. , but then you get different code.

So up to user (you) , to use it not at all, or if you do: know, what you doing and why.

Why i never use it : i want to be 100% sure, the program i make and debug is exactly whats running then permanently .

This is vary bad advice.  Debug and release have different purposes, very importat for proper software development.

So please explain: what different settings you use and why is it useful for "proper" software development.

If you call mi to board i will explain,

Debug from realease  can be diffet only with thiks:

1. optimization level (usually Og for debug, Os for realease

2. release do not need debug symbols - that are stipted etc, 

3. Debug can have enabled some additional code (debug console etc.) (inluded additional library)

Problematic is only haw it is configured, If you change something in project (build setting etc) all options must be changed in all configurations.

(usually IDE gives that possibility, but in eclipse works not to good) try it. choose "all configuration", but it easily users forgot to change this what causes to different settings.

That why i prefer to use own makefiles,  

Then in development process i do not need to change any build setting,  this prevent me form additional regretion tests, 

A took over many projects from peaple that don't use release configurations,  this projects are nightmares do develop.
