Hi All, We successfully installed osmo-bsc, osmo-trx, and osmo-bts-trx in Ubuntu 16.04. All osmo elements were successfully run except for osmo-bts-trx. Upon running osmo-bts-trx while the osmo-trx and osmo-bsc is running, “Aborted (core dumped)” error is shown: ((*)) | / \ OsmoBTS <0017> control_if.c:788 CTRL at 127.0.0.1 4238 <0010> telnet_interface.c:102 telnet at 127.0.0.1 4241 <0012> input/ipaccess.c:884 enabling ipaccess BTS mode, OML connecting to 192.168.1.41:3002 <000b> trx_if.c:589 Open transceiver for phy0.0 <0012> input/ipa.c:129 connection done. <0012> input/ipaccess.c:705 received ID get <0001> oml.c:223 O&M Get Attributes [0], Manufacturer Dependent State is unsupported by TRX. <0001> oml.c:223 O&M Get Attributes [0], Manufacturer Dependent State is unsupported by TRX.

May we know what causes the core dumped? Is it a configuration issue in our side? Attached also are the pcap and config files used and taken during the testing. We used the latest git from "https://git.osmocom.org” for the installation. TIA Best Regard, Ron Menez ron.menez@entropysolution.com<mailto:ron.menez@entropysolution.com>
