ha, that's a bit surprising, as Debian usually keeps their "linux-tools"
package up to date, but for pretty new kernels, yes, might be necessary
to build it yourself.

Thank you Marcus and apologies for the late reply. As it turns out perf is
not included with Raspbian but can be compiled fairly easily:

Hi philip,
to identify such bottlenecks, it's often a nice clue to know which block
consumes the most CPU. I don't know it the Linux perf counters work well
on ARM (simply haven't tried), but if they do: There's a program called
perf. Usage in short
sudo sysctl kernel.perf_event_paranoid=-1
perf
Sean - OK, I understand what you mean now, thank you - the overflow is not
reported until the pressure hits the source block.
Cinaed - In this case it is not my flowgraph but gnss-sdr which I've run
successfully on several platforms. In this case it is running on a
Raspberry Pi 3. I anticipate hitt

It could also be an error in the plumbin
Hi Philip,
Check out line 188:
https://github.com/osmocom/gr-osmosdr/blob/master/lib/osmosdr/osmosdr_src_c.cc
It would appear that other driver writers have followed the lead of Ettus
and use the same letters to indicate the same error. I've only looked at
this code for an entire five minutes, b
Hi Sean,
I am not using UHD blocks, I am using osmocom source/sinks. I did not see
any warnings about changing buffer sizes.
Thank you,

Unless I'm mistaken, only the usrp sink/source blocks report overflow
(source) or underflow (sink). You can see this mentioned in
uhd/docs/general.dox (uhd github repo).
Did you listen to the warnings you get on startup about changing buffer
sizes with a series of commands requiring sudo? That hel
Folks,
Is there a way to diagnose which block first reports an overflow in a
flowgraph?
In my particular instance I am running a flowgraph which is overflowing
without pegging either RAM or CPU.
Thank you,
