I have eight-channel synchronized N210 system on ubuntu 11.04 with i7+8GB computer. I have updated system with latest versions of gnuradio and uhd software.
My flowgraph is an eight-channel multi-usrp source connected to eight data file sinks. I am receiving 200KSa/s from each channel to a RAM-drive (ramFS). The data acquisition is performed in multiple sessions controlled with start() and stop() flowgraph methods.
First recording is OK, there are no overruns. On each subsequent session, there is one or two packet overrun randomly on some channels. This is verified by difference in file size of recorded files. This is causing the data to loose synchronization. How can we correct this situation?
Any ideas here!!!
Thanks,
