[srslte-users] srsLTE on Ettus E310

[Ismael Gomez]

So you said that exactly the same software version and with the same
program arguments runs fine in a desktop PC but not in the E310. That must
be some timing issue or a bug that is only seen with the ARM compiler (e.g.
uninitialized variable).

The "O" messages indicate timing issues, but they don't seem to be a
problem if there are only 4 in 10 minutes and the pos=1545 is always the
same. That indicates that synchronization is correct.

Can you run make test and let me know if all tests are completed
successfully?

Thanks
