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
