I am actually writing to RAM so that shouldn't be the problem. And yes, it also segfaults at lower sample rates (I tried multiple values down to 1) and with a small number of samples (also tried just 1 sample). It would seem that the very idea of reading from the device causes the segfault. cheers -- Stefan Ott Communication and Distributed Systems Institute of Computer Science and Applied Mathematics University of Bern _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
