[Discuss-gnuradio] Possible WBX Board Failure

[devin kelly]

Hello, 

When using a particular WBX daughtercard I get this message from my script:

Current recv sock buff size: 60000000 bytes
mboard0 MIMO master

Warning:
    Unknown transceiver board ID combination...
    RX dboard ID: WBX (0x0053)
    TX dboard ID: Unknown (0xffff)
Traceback (most recent call last):
  File "usrp_spectrum_sense.py", line 366, in <module>
    tb = my_top_block()
  File "usrp_spectrum_sense.py", line 153, in __init__
    self.u.set_antenna(self.antenna)
  File "/usr/local/lib/python2.6/dist-packages/gnuradio/uhd/uhd_swig.py", line 1488, in set_antenna
    return _uhd_swig.uhd_usrp_source_sptr_set_antenna(self, *args, **kwargs)

  in virtual void unknown_rx::rx_set(const wax::obj&, const wax::obj&)
  at /opt/uhd/host/lib/usrp/dboard/db_unknown.cpp:176

The first two lines are normal... but the rest is not.  I've tried to use different machines, different USRP2s, different SD cards (all burned with the same firmware though) and I always get this message.  The only reason why I can think for this happening is a broken WBX board... Can anyone think of any other reason this?

For reference, the WBX serial number is 741, in case there is something wrong with that batch of WBXs.

Thanks for any help,
Devin
