AD9371 TX1 and TX2 are not working

Dear Team ,

                we are working with AD9371 along with ZCU102 .The chip is getting initialised without any error .But Transmitter outputs are not coming . we tested it it by enabling the internal NCO also ,still it is not working . The same configuration files are working for another AD9371 eval board .What could be the reason for this .

Thanks and regards
