Hi,
I am using LPC54608J512BD208 microcontroller in a project. I want to use 32 bit fft functions available in CMSIS library but i am unable to compile the code after calling "arm_rfft_fast_init_f32()" function. I have referred to "Using CMSIS-DSP with MCUXpresso SDK and IDE " but still getting compilation error
"cannot find -llibarm_cortexM4lf_math lpcxpresso54608_hello_world C/C++ Problem"
I have given path of library file located in sdk. My sdk is in same workspace.
I have attached the code for reference. Please help in resolving this issue.
Thanks and best regards,
Prasanna

Please help in resolving the query.
Thanks and best regards,

In addition to the step fromUsing CMSIS-DSP with MCUXpresso SDK and IDE please add
#define __FPU_PRESENT 1 /**< Defines if an FPU is present or not */
in core_cm4.h,and in IDE perspective select the following settings:

Hi Soledad,
I have implemented all the steps mentioned in the link but still unable to compile.
I have uncompressed sdk and then i have given path of CMSIS folder and CMSIS library of SDK. Is that proper?
Please check the code attached for any clue.
Thanks and best regards,
