Hi, I am working on implementing the FFT megacore in my project and I am seeing a problem with the source_error. Here is the info on my FFT:
Here are my problem:
I assert sink_sop, sink_valid, I start transferring data to the FFT and then 8192 clock cycles later (8192 because that is my transform length) I assert the sink_eop.
One clock later, the source_eop got assert and I am getting source_error message 10(Missing EOP) and one clock later source_error message 01 (Missing SOP).
So my question is, what am I doing wrong?

You are probably 1 cycle too late on your EOP signal. Try moving it ahead by one clock and see if it works.
