There’s no way the fpga to ARM channel can support those data rates. Lower
your sample rate to 5msps and try again.

I was setting samp_rate to 1 msps and observed the same situation. In
addition, in the example fosphor samp_rate = 56 msps and no errors
occur.

If you replace the ZMQ blocks with NULL SINK blocks, do the overruns go
away?

Hi Ivan,
The Fosphor block averages and then significantly decimates the FFT output.
With the default settings, it has an output data rate comparable to a 500
kSPS stream. The Fosphor example is also only one channel.
I would suggest starting at a rate of 100 kSPS and increasing from there.
