CMSIS_DSP_401 fails to compile

Hi,

I'm using mbed to develop an application on the STMF32F429ZI Discovery Board. I need to use the DSP that is a feature of this chip but whenever I include the DSP library and attempt to compile my project, it fails to build the DSP library.

Warning: Argument of type "arm_cfft_radix4_instance_q15 *" is incompatible with parameter of type "uint32_t" in "CMSIS_DSP_401/TransformFunctions/arm_dct4_init_q15.c", Line: 4276, Col: 32

Error: Too many arguments in function call in "CMSIS_DSP_401/TransformFunctions/arm_dct4_init_q15.c", Line: 4276, Col: 52

Any help would be appreciated. I want to create a few FIR filters using the instructions I found on this site.

Tom

Hi I am also facing the same problem. Did you figure it out?

No I did not.. it was unable to use the DSP library with mBed. Since I needed high-speed A/D (2 Msps) I ended up using STMCubeMX and GCC/ARM to build my project.
