Hi,
I have the feeling the connection between osmo-trx and osmo-bts-trx is good. The problem is that your BTS<->BSC<->... is failing.
BTs shows these messages at startup because osmo-trx is not yet running: """"
osmo-bts-trx[23221]: <000b> trx_if.c:1174 phy0.0: Open transceiver osmo-bts-trx[23221]: <000b> trx_if.c:185 phy0.0: No satisfactory response from transceiver(CMD POWEROFF)
"""
Then at some point osmo-trx answers: """
ubuntu-HP-EliteBook-8470p osmo-trx-uhd[8282]: Thu Apr 9 11:22:24
2020 DTRXCTRL <0002> Transceiver.cpp:778 [tid=140554180474624][chan=0] command is 'POWEROFF'

2020 DTRXCTRL <0002> Transceiver.cpp:923 [tid=140554180474624][chan=0] response is 'RSP POWEROFF 0' """
But it's already too late, the BTS is already exiting due to some issue in Abis: """
