Dear all, I cross-compiled a small C++ application that records some IQ samples and runs stand-alone on the X410. I want to use a sampling rate from 7.68e6 up to 15.36e6 samples per second. The IQ samples are written into the /run directory. Unfortunately I often get overflows, so that the system is not running stable. The amount of overflows increases if I increase the sampling rate.
I also see overflows, when I run the example benchmark, e. g. like this: /usr/lib/uhd/examples/benchmark_rate --rx_rate 15.36e6 --rx_delay 2 --priority high --rx_spb 64 I tried to play around with rx_spb from 64 to 4096, since I thought that the buffer size would make a difference. But they all showed the same behavior (sometimes overflows, sometimes not). Within htop I cannot see any other CPU consuming services. I was wondering if the processor is to weak to run stand-alone at these data rates. Since I also wanted to run additional decoding on low Modulation and Coding schemes on the processor this might be a problem for me. Could you please give me some information if the x410 should be able to run the benchmark at such a sampling rate stand-alone? For that specific case I unfortunately cannot find and results. Many thanks again and best regards! Jonas
