OK, perfect, thanks Jonathon. I think I should be fine with 512, I just wanted
to make sure that I wasn't doing something crazy (I couldn't find this
limitation documented anywhere, but I am sure it is).

Hey Jason,
Yes 512 is the max SPP, due to the 4k max DMA transfer size. To support
larger FFTs, you could modify the FFT noc block to split up the frames
between multiple packets and issue an EOB on the last packet. I have tried
that in the past and had some success.

Is the max usable SPP size on the E310 capped at 512? In my flowgraph, I have
an RFNoC FFT block. I know that the SPP needs to be set to the size of the FFT
to make things happy and using 512 seems to work fine. As soon as I step up to
1024 I see a lot of errors:
