Hi all,
I'm having trouble running osmotrx with an Ettus B210. I'm not sure where
the issue is so figured I would ask here.
Running the binary for osmo-trx on Ubuntu 18.04, I see:
:~$ sudo osmo-trx
linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown
opening configuration table from path :memory:

Shutting down transceiver...
The output is similar with `sudo osmo-trx -a serial=31502DD`, and the
output of uhd_find_devices looks normal to me:
:~$ uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106501;
UHD_3.13.0.1-release
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
serial: 31502DD
name: MyB210
product: B210
type: b200
I get similar results with or without the suggested udev rules[1].
Looking at the osmo-trx source[2] I am confused why it would identify the
device and then fail the UHD make step. It seems like
`uhd::usrp::multi_usrp::make`
throws exceptions if the device is not found.
I've been stuck on this for a while and would appreciate any pointers or
ideas of what else to try. In case it helps I'll include the output of
uhd_usrp_probe.
Thanks,
