From ad5b10677c91494f87c363e9096b7a2e61e414f6 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Tue, 18 Oct 2016 16:26:11 -0700 Subject: b200: Make sure no GPS settings are applied when no gpsdo present. This changes the exception message thrown when gpsdo is selected as a clock source, but does not change the exception. Note that before, during its first run, the B2x0 would happily accept gpsdo as a clock source even when none was present. --- host/lib/usrp/b200/b200_impl.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'host/lib/usrp') diff --git a/host/lib/usrp/b200/b200_impl.cpp b/host/lib/usrp/b200/b200_impl.cpp index 33f0850eb..9bd2799c2 100644 --- a/host/lib/usrp/b200/b200_impl.cpp +++ b/host/lib/usrp/b200/b200_impl.cpp @@ -1041,8 +1041,11 @@ void b200_impl::update_clock_source(const std::string &source) } _adf4001_iface->set_lock_to_ext_ref(true); } - else if (_gps and source == "gpsdo") + else if (source == "gpsdo") { + if (not _gps or not _gps->gps_detected()) { + throw uhd::key_error("update_clock_source: gpsdo selected, but no gpsdo detected!"); + } if (_gpio_state.ref_sel != 1) { _gpio_state.ref_sel = 1; -- cgit v1.2.3
