Hi Bob,
What USRP / DB are you using?

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.

Hey Jason,
In regards to your original post, I wonder if the issue is due to the split
stream block. Perhaps it has a bubble state and cannot keep up at full
rate. Have you tried moving the Keep One in N before the split stream?

In place of some repo with a git edit, I've copied the relevant changes
from git format-patch below (not sure if it will apply cleanly to the
current codebase, but the intent should be clear). As you can see it's
pretty much a one-liner that just removes the "print" part of the
UHD_SAFE_CALL.

OK, now I am really confused.
Part of my math issue seems to be that I set the "sample rate" in the RFNoC
radio to be my sample_rate because I knew I could ignore due to the lack of DDC
(it would then be set to the master clock rate).
When I run my flowgraph, I see that the master clock rate
I wouldn't mind seeing your solution to #2 as well. The messages certainly
make things look more ominous than they actually are.

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:
