choukoumoun,
Please answer these questions before we could look into the issue:
I have a UMTRX my UHD/OPENBTS or UHD/OSMO-TRX same working fine but wen i start osmo-trx and openbts i have this error
Could you specify where did you get sources and which exact versions and commit numbers do you use?
Did you try to use osmo-trx with Osmocom software rather than with OpenBTS?
