So I assume you modified LOGN in the fft_config.h file to map to the size you want, for example a 512x512 FFT would be LOGN = 9. Just so that this isn't just a compilation thing on the host side I would clean the host application then recompile it since makefiles are often not written to be dependent on include files changing. So it might be that the kernel is recompiled but the host code still thinks LOGN is set to 10 since it wasn't built with an updated macro definition.
