Hi im new to embedded system , I am using IAR compiler to work with ARM ST MCUS
And I want to use CMSIS DSP library which is a big library
The problem I faced is that when I use functions related to Fourier calculation, it gives an out of memory error while I used a small length for Fourier, but the compiler added the whole library to my project, There are notes that IAR stated that modules and variables that are not needed are not used.
And after a lot of searching and asking, ARM-software/CMSIS-DSP#91I found out that it is possible to define a series of rules for the compiler to use only the necessary parts that must be defined before the DSP library is compiled.

In the IAR compiler, CMSIS libraries are added with just one tick.
Now my question is, is it possible to add settings for this library?
And if possible, to which part should these commands be added, because iar has several options

project-->option-->compiler-->preprocess
project-->option-->compiler-->extra option -->command line
project-->option-->assembler-->preprocess
project-->option-->assembler-->extra option -->command line
project-->option-->linker-->define....
project-->option-->linker-->extra option -->command line
.
.
Is there a training video or ... available?

Hi,

I've run into a minor potential issue related to this nice tool.

Description of the possible issue
This issue affects EWlaunch v1.0.
If there is a project with a pre-existing $PROJ_FNAME$.custom_argvars file, EWlaunch is not touching it.
Then, when the EW version selection for the aforementioned project is performed, it does not become persistent across sessions.

Suggested fix
If the project already comes with the $PROJ_FNAME$.custom_argvars and has no EWlaunch information, append the necessary XML keys, in order to get persistence.
