Hi all,

We are trying to run UHD on Odroid XU4 which has Samsung Exynos 5244 (4xA15 
cores @ 2 GHz + 4xA7 cores @ 1.4 GHz with NEON support) and USB 3.0 onboard. 
UHD version is 003.010.002. We managed to build it (essentially just having 
added compiler flags to enable neon support), and it is able to run 
rx_samples_to_file at 20 MHz (w/o storing, since SD is not fast at all), but 
trying to run

rx_samples_to_file --rate 30e6 --freq 1e9 --null

I get permanent OOOOOOO series from the very capture start. Did anyone succeed 
to run the capture on XU4 at 30 MSps? With htop I can see that the example runs 
on lower 4 cores of XU4 which are low-rate A7 cores (it uses them at average 
50% though). Is it possible to force it to run on high-power cores?

I tried to put 4 lower cores offline, but then rx_samples_to_file freezes the 
whole system after printing "Waiting for "lo_locked": ++++++++++" (the 
following " locked." never gets printed, and all other remote connections to 
the system freeze; only power cycle helps).

What is the decent way to test usb3 input speed with such a setup?

Vladimir
