I am having a similar problem. I used ethtool to disable the pause parameters for this interface; here is the output: sudo ethtool -a eth1 Pause parameters for eth1: Autonegotiate: off RX: off TX: off
But I still get this error when i run tx_samples: sudo ./tx_samples -e eth1 terminate called after throwing an instance of 'std::runtime_error' what(): Unable to retrieve daughterboard info Creating USRP2 Object.... Aborted I'm running the latest version of GNU Radio (freshly re-complied this morning, revision 10644) on Ubuntu 8.10. I have a USRP2 with the firmware and bit file that was complied on March 15th 2009 and the xcvr2450 daughterboard. Are there any other ideas as to what could cause this (or did I disable flow control pause wrong)? Thanks! Newman, Timothy wrote: > > I had a similar problem when I was using a PCIe express card.
