Michael Benedict michael at usehover.comHi all,
I'm trying to get OsmoTRX working with a B210 on Ubuntu 18.04. I
recently posted to the USRP Users list but haven't had success yet, so
posting here.
Since the message below I've tried both the osmo-trx and osmo-trx-uhd
binaries with several example config files on github. My next step
will be to compile from source and try to debug the "UHD make" issue,
but these binaries have worked for others so I hope I'm just missing
something.
Sincere thanks for any info. I'm new to this area but very excited to
learn more.

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

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,
