Have you tried a lower SPP (eg. 256)? AFAIR, I had trouble with higher SPP for some blocks. Otherwise, it seems similar to https://github.com/EttusResearch/uhd/issues/406 Regards -- Cédric Hannotier _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
