Cellular Network Infrastructure » OsmoGSMTester

I started installing all required bits missing in the prod main unit.

I had to modify the jenkins job with the following, as the modems used there differ fromt the ones configured by default in the repository (the ones from R&D):

# TMP fix: prod main unit has sierra_2 and _3 instead of _1 and _2
sed -i "s#sierra_2#sierra_3#g" "$OSMO_GSM_TESTER_CONF/resources.conf" 
sed -i "s#sierra_1#sierra_2#g" "$OSMO_GSM_TESTER_CONF/resources.conf" 
sed -i "s#901700000009031#901700000015252#g" "$OSMO_GSM_TESTER_CONF/resources.conf" 
sed -i "s#901700000009029#901700000015253#g" "$OSMO_GSM_TESTER_CONF/resources.conf" 

I reach a point in which the sysmo tests are working, but the trx ones fail. For now I'll switch back to use the R&D one until can solve the following issues.

I followed the osmo-gsm-tester manual (http://ftp.osmocom.org/docs/latest/osmo-gsm-tester-manual.pdf) and the wiki page (https://osmocom.org/projects/osmotrx/wiki/OsmoTRX#UHD) to set up the UHD.
I had to use the repos mentioned there from jessie-backport to have the same versions of the libraries as I have in R&D (working env).

The device is recognized on the prod env (problematic env):

# uhd_find_devices
linux; GNU C++ version 4.9.2; Boost_105500; UHD_003.009.005-0-unknown

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
    type: b200
    name:
    serial: 306BD11
    product: B200

The only difference with R&D (working env), apart from serial, is the name, which is not set:

# uhd_find_devices
linux; GNU C++ version 4.9.2; Boost_105500; UHD_003.009.005-0-unknown

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
    type: b200
    name: MyB200
    serial: 30A9FFB
    product: B200

However, start of osmo-trx fails, both inside jenkins, and also if I run it with user root manually:

# LD_LIBRARY_PATH=$PWD/lib bin/osmo-trx -x -l DEBUG
linux; GNU C++ version 4.9.2; Boost_105500; UHD_003.009.005-0-unknown

PS: Adding Tom as watcher as he may have more knowledge on the insides and can provide a quick answer on what may be wrong.
