[srslte-users] USRP-2920

Hello, our team is trying to stand up SRSLTE on two USRP-2920s. The
documentation indicates that this hasn't been successfully tested on this
device but we would like to try.

To this point, we have been able to get the core, eNodeB, and UE to run.
To get the UE and eNodeB to start, we needed to change the clock to
external through the device arguments. We thought that if we supplied a
10MHz reference clock to the USRP that we could get the eNodeB to function
correctly.

Unfortunately, when the eNodeB finalizes startup we receive numerous 'LL's
which we assume are originating from UHD and the UE will not connect.

Does anyone have any recommendations on how to get around this?

Thanks much
Mike
