No I have not 'butch' in an EEPROM and I have done nothing that could have
hosed the USRP. All I did is put two small leads on the mating connector to
input a signal. The only signals that I tried to input so far are from a
generator +/- 0.5 Vpp sine/square wave and about 5 feet long wires to try
and pickup a local FM. I have not tried to insert my actual signal yet.
In python interactive mode I have done the following:
Python >> u=usrp.source_c()
'RX d'board A:<none>'
'RB d'board B:<none>'
Python >> sbdev = (0, 0) #default subdev
Python >> u.subdev=usrp.selectected_subdev(u, sbdev)
Python >> u.subdev.side_and_name()
'A:<none>'
Python >>
Note that I did not get the warning message. Should I have gotten it? From
the last command it looks like the subdev is 'A:<none>', is this what it
should be if it defaults to Basic RX daughterboard?
