Hi Folks, I know a few of you were having problems with certain gigabit ethernet cards. I've fixed a couple of what I think are relatively minor bugs in how we were setting up the usrp2's ethernet PHY chip to advertise our capabilities.
We now correctly advertise: That we ONLY do 1000BASE-T That we'd like to send PAUSE frames and will ignore any received PAUSE frames. The fix is in changeset [10634] in the trunk and I've uploaded a new firmware binary for those of you who might like to try it: http://gnuradio.org/releases/usrp2-bin/trunk/txrx_edk10.1_r10634.bin With this change, the green LED on the RJ45 connector will no longer light unless you're plugged into a device that can do gigabit ethernet. In addition, if you've got the debugging serial port hooked up, the firmware will report the kind of flow control that was ultimately negotiated. If says anything other than ethernet flow control: WE_TX it means that the device the usrp2 is hooked to wouldn't accept our request for asymmetric flow control, and that as a result any non-rate-limited transmission (e.g., usrp2_sigggen.py) is likely to fail miserably. We'll find a way to get this information back to the host app as part of the VRT work that will come sometime after we get 3.2 out the door.
