Apologies for a simple question here, I've followed the usage instructions and explored all option to resolve the issue but with no luck.
We are are having trouble in compiling the arm_fft_bin_example.ewp. There is linker error for the arm_cfft_init_1024_f32 function.
I have added below library -
C:\Program Files\IAR Systems\Embedded Workbench 9.2\arm\CMSIS\Lib\IAR\iar_cortexM4lf_math.a
I have added below path for header files -
..\IAR-CMSIS-DSP\CMSIS_5\CMSIS\Core\Include
..\IAR-CMSIS-DSP\CMSIS-DSP\Include
..\IAR-CMSIS-DSP\CMSIS-DSP\Include\dsp
Development environment
Are we missing any additional settings.
Additionally can anyone please confirm example is for 1024 samples but testInput_f32_10khz (test input data) is of 2048, it is always expected the data samples to be double of processing samples??

Can you share the specific linker error you are getting?
For the details, I am pretty sure @christophe0606 can provide answers.
Please take note that we splittet off CMSIS-DSP into its own repo a while ago. You find it's new home at https://github.com/ARM-software/CMSIS-DSP. The library became its own pack, so it might be much easier to update it independently from other software components, now.
@vipinthomas123 Note that the function arm_cfft_init_1024_f32 is recent. If you're using a too old CMSIS-DSP you won't get it. Please open a new github issue on the CMSIS-DSP repository
