Hi,
I'm trying to synchronize two N200s in phases with both of them having
GPSDO inside. I followedthe instructions on ettus for synchronizing channel
phase. However, I got error message as follows,
UHD source block got error code 0x2gr_block_executor: source <gr_block gr uhd
usrp source (19)> produced no output. We're marking it DONE.UHD source block
got error code 0x2gr_block_executor: source <gr_block gr uhd usrp source (18)>
produced no output. We're marking it DONE.
and here's part of my code:bool start(void){ #ifdef
GR_UHD_USE_STREAM_API _rx_stream = _dev->get_rx_stream(_stream_args);
_samps_per_packet = _rx_stream->get_max_num_samps(); #endif
//setup a stream command that starts streaming slightly in the future
static const double reasonable_delay = 0.5; //order of magnitude over RTT
uhd::stream_cmd_t
stream_cmd(uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_DONE);
stream_cmd.num_samps = 200000; stream_cmd.stream_now = false;
stream_cmd.time_spec = uhd::time_spec_t(reasonable_delay);
_dev->issue_stream_cmd(stream_cmd); _tag_now = true; return true;
}
Thanks for any help in advance.
Best regards,
Oliver _______________________________________________
