From 41f732a4c8bb9df116a01958f0914708475097df Mon Sep 17 00:00:00 2001 From: Sugandha Gupta Date: Tue, 5 Mar 2019 11:37:13 -0800 Subject: ad9361: Fix return values for tune and set_clock_rate This fixes a potential mismatch between the returned frequency and clock rate and the actual value. The new function get_clock_rate is need for async call to set_clock_rate in E3xx devices --- host/lib/usrp/common/ad9361_driver/ad9361_device.cpp | 11 ++++++++--- host/lib/usrp/common/ad9361_driver/ad9361_device.h | 3 +++ 2 files changed, 11 insertions(+), 3 deletions(-) (limited to 'host') diff --git a/host/lib/usrp/common/ad9361_driver/ad9361_device.cpp b/host/lib/usrp/common/ad9361_driver/ad9361_device.cpp index 16bcadd2d..f0e10871e 100644 --- a/host/lib/usrp/common/ad9361_driver/ad9361_device.cpp +++ b/host/lib/usrp/common/ad9361_driver/ad9361_device.cpp @@ -1911,10 +1911,15 @@ double ad9361_device_t::set_clock_rate(const double req_rate) break; }; - return rate; + return get_clock_rate(); } - +/* This function returns the RX / TX rate between AD9361 and the FPGA. + */ +double ad9361_device_t::get_clock_rate() +{ + return _baseband_bw; +} /* Set which of the four TX / RX chains provided by AD9361 are active. * * AD9361 provides two sets of chains, Side A and Side B.
