use GPSDO in my application. Since there is no GPS antenna with
GPSDO-kit, I bought a 'SMA male straight GPS antenna'. Everything went
well before I connect the GPS antenna to the GPSDO. For example, I can
receive GPS time using usrp->get_mboard_sensor("gps_time"). Other uhd
applications also work well.

the GPS time, I connected the GPS antenna to GPSDO. However, I got some
weird errors. I even got the same errors when I run 'uhd_usrp_probe'.
