Did something change with respect to daughter board addressing in UHD 3.11?
I have an X310 with LFTX and LFRX in motherboard slot A.
When I run benchmark_rate it core dumps as follows:
/*

If I specify tx_channels "1" it runs, lighting up the slot B TX/RX LED, or
course I have no boards installed there.
/*
[/usr/local/lib64/uhd/examples]$ ./benchmark_rate --args "addr=192.168.40.2"
--tx_rate=100E6 --tx_channels "1"
*/
If I specify tx_channels "0" it core dumps with the same std::out_of_range
Flow graphs that ran in UHD 3.10 with sub-device "A:AB" no longer run:
/*
[INFO] [CORES] Timer loopback test passed
terminate called after throwing an instance of 'std::out_of_range'
what(): map::at
*/
If I try benchmark_rate with another X310 with the UBX card in slot A, things
work fine. So maybe it's specific to the use of LF cards with UHD 3.11.
Thanks,
Lou
