Error occurred in 'hdlfft/HDL Streaming FFT'. Error reported by S-Function 'sdspfft2' in 'hdlfft/HDL Streaming FFT/FFTCore/SimulinkFFT': The input data type must be double precision, single precision, integer, or fixed point with power-of-two slope and zero bias.
How do I solve this problem? Thank you

The error message seems pretty clear: it's stating that the HDL Streaming FFT block requires one of a class of certain data types as input. What type are you feeding into the block, and is it one of the listed supported types?
* double
* single
* integer
* fixed point (slope/bias mode not supported)
