Hi.
I've been developing with nRF54L15DK.
I added below in prj.conf.
Indeed, I could confirm CMSIS-DSP function normally running in main.c.
In my goal, I would like to use .a library file, which requires CMSIS-DSP .
In the MDK-Arm environment, its default configuration does not activate 128 points FFT.
I would like to refer below explanation and adopt its configuration.
then, I placed the library(.a) and header file(.h) as below.
.a : src/app/lib
.c,.h : src/app
then, I wrote in CMakeLists.txt
and, I added "include "arm_math.h"" in header file for linking.
but, it failed to build , mainly found 'undefined reference to "arm math function" '.
(below is part of build error)
It seemes for me to require the CMSIS-DSP function, but I already set in prj.conf
How should I solve this confliction?
Best regards.
